Biographical / Historical:
S. Newman Darby is recognized as the first person in the United States to conceive of connecting a hand-held sail rig fastened with a universal joint to a floating platform for recreational use. He called it sail boarding in 1965, when he published his designs in Popular Science Monthly magazine. Although he and his brothers Ronald and Kenneth began manufacturing the boards through their company Darby Industries, they never applied for a patent.
S. Newman Darby (1928-2016) was born in West Pittston, Pennsylvania. He graduated from West Pittston High School in 1946. A sign painter and artist, like his father Sidney Darby, he studied drafting at the Pennsylvania State University extension school where he took chemistry, business, art, and photography courses for one year. His first invention, the Darby Dory, a folding rowboat dates from 1953. The sailboard developed out of Darby's experiments with a personal pontoon catamaran, each hull being big enough for one foot and designed to be operated with a hand-held sail and no rudder. By 1964 he had designed a universal joint that connected a mast to a flat bottom sailing scow. This board had a centerboard, tail fin and kite shaped free sail. Early tests were conducted on Trailwood Lake and the Susquehanna River, near West Pittston.
Today sail boarding is known as windsurfing. It adopted its name from Windsurfer International, a company Hoyle Schweitzer and Jim Drake established on the basis of a patent granted to them in 1970 for a "wind-propelled apparatus." In all essential qualities, their claims duplicated Newman Darby's earlier work.
After Schweitzer bought out Drake's share in 1973, he energetically promoted the sport and licensed manufacturing rights to more than 20 companies around the world. Schweitzer forcefully prosecuted patent infringements he perceived among windsurfer manufacturers and he threatened to sue the 1984 Olympic Committee should it authorize a board produced by a manufacturer not licensed by Windsurfer International.
Although he was aware of the growth of the sport and the profits flowing into Windsurfer International through its licensing activities, Darby was unable to mount a legal challenge to Schweitzer. His priority in the invention of the sport was overlooked and almost forgotten.
In the late 1970's, Mistral, a Swiss manufacturer sued by Windsurfer International in Germany, located Darby and presented his "prior art" as a defense. In the early 1980's, courts in the United States were asked to rule on the validity of the Windsurfer International patent. Newman Darby's prior art was at the center of the controversies. The court voided Windsurfer's original patent and Schweitzer was forced to apply for a reissue based on severely limited claims. He lost the use of "windsurfer" as a trademark. Schweitzer retained the reissued patent through further challenges until it expired in 1987. The example of Newman Darby has become a textbook case of the importance of thorough searches for "prior art" for patent attorneys.
Following completion of the patent litigation Darby designed original sail rigs for Mistral in Europe and Horizon in the United States. In 1982 Newman entered into a new partnership with his brothers Ronald and Kenneth and formed NRK, Inc., to design and manufacture windsurfing boards, training devices and to produce written and video documentaries of his contributions to the history of the sport.
Naomi Albrecht Darby, Newman's wife, sewed the first sails for the boards and participated in their testing and marketing. She documented Darby's inventions through the years in photographs and moving images. Over the years, Darby has worked on numerous inventions--most of them related to wind propulsion. Like many independent inventors, Newman Darby conceives of his ideas, executes all of the mechanical plans, builds his own prototypes and tests them. Darby continues to research improvements in windsurfing and to teach courses in boat building and design.

Biographical / Historical:
Lisa Lindahl was frustrated by the inadequacy of her everyday bra when she began jogging in the early 1970s. When her sister, Victoria Woodrow began jogging she met with the same issues and called Lisa to ask what she did about it. Commiserating over their problems, Victoria asked, "What do you do about all the breast movement? It's so uncomfortable." And Lisa said, "I don't know. It really is uncomfortable." Victoria said, "Why isn't there a jock strap for women?" Lisa laughed back and said, "Yeah, same idea, different part of the anatomy. Wouldn't that be great?" The sisters hung up laughing and Lisa sat down and opened up a spiral notebook to record her thoughts and design criteria for this "jock bra." "Here's a bra made just for jogging. What would it do?" And Lindahl wrote, "Okay, the straps would not fall off my shoulders and there wouldn't be any hardware to dig in and it would be comfortable and maybe even breathable, and it would stop my breasts from bouncing."
Lindahl engaged her childhood friend Polly Palmer Smith in her effort to solve the bra problem. They found no suitable products in retail stores, but were inspired by Lisa's husband, Al Lindahl, who took a jock strap and pulled it over his head and down over his chest and said, "Hey ladies, here's your jock bra." Lisa said, "I had to get into the act, so I jumped up and said, "Let me try it. Let me try." And I pulled his jock strap up and over my head and pulled the pouch over my breast and the waistband of the jockstrap went around my rib and I kind of jumped up on bed and I said, "Polly, Polly, look at this, look at this." They went to multiple stores and inquired but could not find a bra that fit their needs--a bra that kept the breasts pressed flat against the chest and eliminated motion. They also wanted something without seams and hooks, wire or other metal elements. Lindahl, along with Polly Palmer Smith, a childhood friend from New Jersey, sewed a pair of jockstraps together creating a few prototypes.
Smith introduced Lindahl to Hinda Schreiber, a fellow costume designer and classmate at New York University. Schreiber worked as an assistant to Smith at the Champlain Shakespeare Festival held at the University of Vermont in the summer of 1977. With interest in and enthusiasm for the idea of creating more jogbras, Schreiber joined Lindahl and Smith. They called their product the "jockbra" but later changed it to "Jogbra," figuring that the word "jock" might be a turn-off for some women. On November 20, 1979, US Patent 4,174,717 for an athletic brassiere was issued to the three co-inventors. Subsequent US patents include:
Eugenie Z. Lindahl, Hinda S. Schreiber, and Polly P. Smith, Des. 259,370 for a brassiere, 1981; and US 4,311,150 for an athletic brassiere, 1982.
Eugenie Z. Lindahl and Hinda Schreiber, Des. 260,445 for an athletic shirt, 1981 and Des. 301,518 for a brassiere, 1989.
LaJean Lawson and Hinda Miller, US 6,083,080 for a protective brassiere with local energy absorption, 2000.
Lesli R. Bell and Eugenie Z. Lindahl, US 6,860,789 for a compression garment, 2005.
Lindahl started the company Jogbra, Inc. in 1977 and then re-named it SLS, Inc. (for Smith, Lindahl, Schreiber) in early 1978. As President of the company, Lindahl issued equal shares to herself, Smith and Schreiber. The name changed again to Jogbra Inc., for a brief time, before finally becoming JBI, Inc. in the early 1980s. Marketing their new product (with start-up capital lent by Miller's father, Bruce L. Schreiber) was a challenge. According to Lindahl, buyers for sporting goods stores were "squeamish" about displaying bras, which did not look like lingerie, but an athletic garment. Stores that did feature the jogbra were pleased by how well it sold. Miller placed strong emphasis on the point of purchase advertising and packaging. The jogbra line of products expanded to include a women's and men's sport brief, the Thermobra and Thermobrief. Soon, a number of other manufacturers, including Vanity Fair, Olga, and Warner, were entering the sports bra market.
Hinda Schreiber Miller (April 18, 1950-) was born in Montreal, Quebec, Canada. She graduated from the Parsons School of Design (B.F.A., 1972) and from New York University (M.F.A., 1976). A costume designer by training, Miller taught costume design at the University of South Carolina. Miller later became a Vermont state senator (2002-2013) representing the Chittenden District which includes all of Chittenden County. Miller ran unsuccessfully for mayor of Burlington, Vermont in 2006. She is presently president of DeForest Concepts, a consulting firm specializing in small business and the promotion of women entrepreneurs. Miller is married to Dr. Joel Miller and has two children.
Polly Palmer Smith (November 10, 1949-) was raised in Montclair, New Jersey. She graduated from the Moore College of Art & Design with a (B.F.A., 1971) and New York University (M.F.A., 1975). She joined the Jim Henson Company in 1978 where she worked as a costume designer for twenty-five years. Smith worked on films such as the Dark Crystal, The Muppets Take Manhattan, and Labyrinth. Some of her television work includes Fraggle Rock and Muppet Treasure Island. Smith received Emmy nominations for her designs for The Jim Henson Hour (1988) and Muppets Tonight (1996) and she received seven Emmy awards for her designs on Sesame Street. Smith also co-designed costumes for the television series The StoryTeller (1986-1988) which won a British Academy of Film and Television Arts (BAFTA) award for Best Costumes in 1989.
Historical:
The introduction of the sports bra made greater sports participation possible for many American women. Many women were reluctant to engage in sports such as running, basketball, and tennis because of the embarrassment and discomfort associated with excessive breast motion. The passage of Title IX (1972) and James Fixx's popular 1977 book, The Complete Book of Running, contributed to the increased popularity of sports for women. This increase in women's sports exposed the inadequacies of conventional brassieres for athletic use: weight shifts from bouncing caused straps on ordinary brassieres to slip around or off the shoulder; excessive motion caused friction and chafed skin; and hooks or other metallic elements tended to poke into the skin; and excessive bouncing caused soreness.

Biographical / Historical:
Started in 1898 in Brockton, Massachusetts by Walter Thomas Stall and Charles Dean, the Stall and Dean Company is one of the oldest sporting goods manufacturers in America. Their first catalog offered baseball and basketball uniforms, and footballs and football helmets. The business rapidly expanded, and within a few years, they were producing athletic shoes for numerous sports: caps, bats, balls, mitts and fielding gloves for baseball; boxing gloves; tennis rackets; nets for tennis and volleyball; and supporters and protective equipment. Eventually, Mr. Stall bought out Mr. Dean's share of the business, but the company name has remained Stall and Dean.
Stall and Dean was the first American company to manufacture hockey jerseys and equipment, outfitting the original six member teams of the National Hockey League. Many Hall of Fame athletes from many sports wore Stall and Dean uniforms, including Bobby Orr and Ted Williams, and their catalogs contained endorsements from many famous players, including Ty Cobb. They manufactured uniforms and equipment for high schools and colleges as well as for the pros. With the "Safeslide" flannel baseball uniform being just one of their innovations, they adapted to the changing times and changes in style and materials in sports apparel, and these changes are well documented in the company's catalogs. In a 1975 article in the Brockton Enterprise, Richard Stall, Jr., the third generation owner of the company, extolled the virtues of polyester double knit fabrics, saying "...they look marvelous and they have replaced flannels." While the company adapted to stylistic changes, it has remained in its original factory and still produces uniforms on some of the same turn-of-the-century sewing machines it purchased new. In a 1998 article in Yankee magazine, an employee named Kevin Gosciak referred to Stall and Dean as "a museum of American manufacturing."

Howard Head was born July 31, 1914 in Philadelphia, Pennsylvania. He attended William Penn Charter and graduated from Harvard in 1936 with a degree in engineering. From 1939 to1947, Head worked for Glenn L. Martin Company as a riveter and engineer. He left Martin and founded the Head Ski Company in Timonium, MD in 1948. The former aircraft engineer, developed, designed, manufactured, and marketed the first metal laminate skis in 1950 called the "Head Standard" which revolutionized the ski industry. These skis were made of two layers of aluminum bonded around a core of plywood at very high pressure; the outer layer was made of plastic. By 1952, Head introduced skis with edges made of tempered steel. His skis were lighter and faster than wood and earned the nickname "cheaters" by the industry. In 1969, Head introduced a fiberglass/metal ski, but this ski combined with a diversified product line of javelin and aluminum tennis rackets could not strengthen his company nor stop a takeover by AMF in 1970. In 1968, Head formed a tennis division of Head Sports Inc., to develop a metal tennis racket which he introduced at the U.S. Open in 1969. After Head sold his interests in Head Sports Inc., he became chairman of the board for Prince Manufacturing Inc., in 1971. He decided to enlarge the width and length of the traditional tennis racket, more than doubling its "sweet spot." He developed and patented a line of new aluminum rackets and introduced the "Prince Advantage" in 1976. The Prince racket company was sold to Cheesebrough Ponds in 1982. Head, who died in 1991, revolutionized both the ski and tennis industries.

Biographical / Historical:
Sherman Poppen (1930-2019) was born in Muskegon, Michigan. He graduated from Northwestern University in 1952 and served in the United States Navy as a supply office at sea from 1952-1956. He owned an industrial business, Lake Welding Supply Company, which sold gases and welding supplies in Muskegon, Michigan.
On December 25, 1965, Poppen created the snurfer, a predecessor of the snowboard, by binding two children's skis together. His wife, Nancy, was pregnant with their third child and his two restless daughters, Wendy and Laurie, wanted to play on Christmas day. Poppen entertained them by playing outside in the snow. The girls' desire to stand up while riding on a sled and Poppen's vision of snow drifts as waves collided, and the idea for the snurfer was born. Nancy coined "snurf" by combining the words snow and surf. Neighborhood children soon began asking for snurfers of their own. Poppen decided to patent his creation (US Patent #: 3,378,274 --Surf-Type Snow Ski) and trademarked the words snurf and snurfer (US Trademark #: 1,518,101). It was also patented in Canada (Patent #: 819,596). In 1966, he licensed the product to the Brunswick Corporation and worked with them to create a board from the laminated wood used for bowling alley gutters. Brunswick manufactured the snurfer and sold it as a novelty item, not sports equipment, and it gained popularity. From 1968 through the late 1970s, snurfer racing competitions were held in Muskegon at Blockhouse Hill. In 1972, Brunswick discontinued production of the snurfer, but JEM Corporation continued manufacture until the early 1980s. By 1977, Jake Burton Carpenter, an avid competitive snurfer, began developing an improved model without a rope handle and with the addition of rigid bindings for ski boots to the board. As more resorts began allowing snowboards on their ski lifts, the popularity of the snurfer waned.
Poppen took up snowboarding at the age of 67. He received recognition from the snowboarding community as the grandfather of the sport and was inducted into the Snowboarding Hall of Fame in Banff, Canada in 1995 and the Muskegon Area Sports Hall of Fame in 2001.

Arthur Ehrat invented and patented a breakaway basketball rim, fashioning his prototypes from bolts, metal braces and one key part: a piece of the heavy-duty coil spring on a John Deere cultivator. His invention helped to revolutionize the way basketball is played because players could slam dunk the ball with fewer injuries and without bending the rims or breaking backboards. This collection includes correspondence, legal documents --such as patent papers, litigation files and licensing agreements --photographs and sketches that relate to the basketball invention, as well as materials regarding his two field spreader patents and other invention ideas.
Scope and Contents:
The collection is divided into five series and consists of approximately seven cubic feet.
This collection includes correspondence and legal documents--such as patent papers, litigation files and licensing agreements--that relate to Arthur Ehrat's basketball goal, as well as materials regarding his field spreader patents and other invention ideas. The bulk of the collection is made up of attorney correspondence, patent infringement documents, and patent licensing documents. The collection also contains handwritten notes by Arthur Ehrat and his attorneys, sketches of his inventions, an oral history interview, and photographs.
Attorney McPherson Moore sent many of the legal documents and correspondence to Ehrat. These documents were assembled by the law firms for which Moore worked. The original order has been preserved.
The correspondence consists of letters from attorney McPherson Moore to Ehrat and from Moore or his associates to other attorneys regarding litigation, pending licensing agreements, and other actions. The correspondence contains handwritten notes, promotional materials for sporting goods companies, drafts of legal documents, copies of patents and other enclosures. The majority of the correspondence is copies.
Correspondence found throughout the collection is key to understanding the legal documents because it provides insight into the legal negotiations behind the settlement and licensing process, and the diligence necessary to protect a viable patent from infringement. Correspondence should be read in conjunction with litigation and licensing documents to gain a better sense of the negotiations between attorneys and how and why the legal documents were created.
Throughout this collection, reference is made to legal terms, including pleadings, production documents, discovery, patent infringement, file histories, and Bates numbers. Series 3, Civil Action and Settlement Records has numerous sets of pleadings, which are the legal documents filed in a lawsuit. These documents encompass complaints, petitions, answers, motions, declarations, and memoranda.
The discovery process is the effort of one party to a lawsuit to get information from the other party prior to a trial. This is done through depositions, requests for or production of documents, and interrogatories (written questions to the other party).6
Bates numbers --named after the Bates Automatic Numbering Machine patented in the late 1800s --are used to identify documents with a unique number. The parties to a lawsuit use these numbers to keep papers in order when they are sent to the other party during discovery. This collection contains sets of production documents stamped with Bates numbers. (See Series 3, Subseries 8: Ehrat v. Icon, Proform and K's Merchandise, 1984-1996)7
Patent infringement is "the manufacture and/or use of an invention or improvement for which someone else owns a patent issued by the government, without obtaining permission of the owner of the patent by contract, license or waiver."8
A patent file history (also called a file wrapper) is a folder maintained by the United States Patent and Trademark Office. It contains all of the correspondence and documents from a patent application.9 See Series 2, Subseries 2 for the file history of Ehrat's United States Patent No. 4,365,802.
Series 1: Background Materials, 1968-2005, 2011
This series, which is further divided into three subseries, comprises oral history interviews, early sketches of Ehrat's basketball goal, articles about slam dunking, Ehrat's breakaway rim, correspondence and notes, income and expense records (including legal expenses), photographs and facsimiles of photographs, and invoices from the components Ehrat purchased when he created prototypes. One receipt documents the heater Bob Copelin purchased for his new shed in 1975, around the time Ehrat began inventing. This was significant when Ehrat was trying to prove to the United States Patent Office that he had his idea before Frederick Tyner.
Subseries 1: Ehrat History, 1968-2005
Correspondence in this subseries includes a handwritten list of possible names for the basketball rim, one which Ehrat titled, "The Rebounder Has Been Tested." The correspondence also contains copies of letters sent to the United States Patent Office intended to prove that Ehrat's rim was unique; a letter from National Basketball Association saying that, after testing, it is going to use Kenneth Mahoney's (Toss Back) rim instead of Ehrat's; letters from basketball halls of fame; and copies of e-mail from the Smithsonian. This subseries has an original sketch of Ehrat's basketball goal with annotations. Also included is a 1 D2" VHS tape of Ehrat explaining the components he used to fashion his first breakaway rim prototypes and a news segment in which Ehrat was interviewed about his invention at the Chicago Board of Trade. The audio and video recordings contain some repetition of information.
Subseries 2: Photographs and Clippings, 1973-2005
Color photocopies of photographs depicting early rims; a birthday gathering for Ehrat's father, William Ehrat, circa 1974-1975 (used to help prove that he was working on the rim before Frederick Tyner); Ehrat giving a rim to Virden High School; Ehrat with sportscaster Dick Vitale; and a studio shot of his daughters, Rose, Jo, Sharon, Jane, and Linda.
Three photographs in this subseries show prototype rims with coil springs. Ehrat holds up one of these photographs in the video history, but he does not discuss the photographs' origin. There are no markings of any kind on the photographs.
Subseries 2 also contains field photographs taken by John Fleckner, National Museum of American History staff, in May 2005. Field photographs include: the grain elevator Ehrat managed; rim prototypes; and a donated rim hanging on the gym wall at Virden High School.
Articles in this subseries are from the Virden Recorder, The State Journal-Register, Chicago Tribune, The Wall Street Journal, and Kentucky Living. The topics covered include collapsible rims and breakaway rims; Ehrat and his invention; and the Smithsonian Institution's interest in the breakaway rim. Also included is a clipping from Farmers Elevator Co.'s meeting minutes from December 15, 1973, in which the board voted to relinquish rights to any patent or product created by Ehrat.
Subseries 3: Oral History Interview, 2005
A May, 2005, interview of Ehrat by John Fleckner at Ehrat's home in Virden, IL. Ehrat discusses his background, attorney Ralph Staubly, basketball rims he built, and a slam dunk contest that his nephew Randy Albrecht helped organize in the early 1980s at St. Louis Community College. Subseries 3 also contains Digital video disks (DVD) in which Ehrat discusses the documents he sent to the Archives Center, National Museum of American History. There is some repetition of topics discussed in the audio and video recordings.
Series 2: Patent Records for Basketball Rim, 1865-1984 (bulk 1970s-1984)
This series, divided into four subseries, contains copies of patents used as research or as prior art for Ehrat's patent application, a file history of the patent, correspondence/notes from Ehrat and his attorneys, and legal papers sent from Ehrat's first attorney, Ralph Staubly, to McPherson Moore.
Subseries 1: Ehrat and Dittrich Patents, 1979-1984
Copies of Ehrat's United States Patent No. 4,365,802, deformation-preventing swingable mount for basketball goals and William Dittrich's two patents, United States Patent No. 4,151,989, basketball practice device and United States Patent No. 4,465,277, basketball goal structure.
Subseries 2: Research and File History, 1865-1984
The complete patent file history consists of a list of actions taken (rejections, appeals, civil action filed) on the patent application for United States Patent No. 4,365,802. Pages 19-23 are copies of letters sent to United States Patent Office to establish the rim's unique qualities after the examiner's interference search found Frederick Tyner's patent (United States Patent No. 4,111, 420, Energy-absorbing basketball goal/backboard unit) and ruled Ehrat's invention was too similar.
Subseries 3: Correspondence and Notes, 1976-1984
Two sets of letters from acquaintances. The first set, 1977-1978, was sent to the United States Patent Office and provide a sense of the invention's unique quality. The second set, 1983-1984, consists of letters written by Ehrat's friends and was used in Basketball Products International and Ehrat v. Mt. Vernon School District and Porter (Series 3, Subseries 1) to establish that Ehrat had his breakaway rim idea before Frederick Tyner. A letter in the correspondence folder for this litigation, dated February 23, 1984, mentions that copies of these letters were sent to Basketball Products International. Also in this subseries is a transcript of a phone conversation between Ehrat and attorney McPherson Moore about when Ehrat had the idea for a breakaway rim and who knew about it.
Subseries 4: Files from Ehrat's First Attorney, Ralph Staubly, 1976-1982
Includes the file about Ehrat sent from Ralph Staubly to McPherson Moore when Ehrat changed legal representation in 1983. The folder contains originals, copies, and drafts of documents sent to the United States Patent Office, some with annotations. Also included is a high school basketball rulebook, 1977-1978, and the notes Ralph Staubly used to write an affidavit for Ehrat's patent application in which Ehrat swears he invented before Frederick Tyner.
Series 3: Civil Action and Settlement Records, 1984-1996
This series is divided into eight subseries. It contains full and partial sets of case pleadings, with pleadings indices, from eight court cases, attorney correspondence and notes, depositions of Ehrat and Frederick Tyner, case judgments, and signed settlements.
In 1984, Ehrat and Basketball Products International were plaintiffs or defendants together in five civil action lawsuits that involved sporting goods companies, including Porter Equipment Company, Gared Company, and Toss Back. These lawsuits and their correspondence should be consulted in conjunction with one another.
Subseries 1: Basketball Products International and Ehrat v. Mt. Vernon School District and Porter, 1984
Civil action, February 1984-June 1984: The complaint alleges patent infringement by sporting goods company Porter for manufacturing products embodying the invention, and infringement by Mt. Vernon School District (WA) for purchasing Porter basketball goals. Action dismissed June 11, 1984. This subseries contains the subpoena and deposition of Frederick Tyner regarding United States Patent No. 4,111, 420, Energy-absorbing basketball goal/backboard unit. It also contains plaintiff's exhibits, numbered 1-31, which include Tyner's notes, documents, and facsimiles of photographs related to his patented basketball goal.
Subseries 2: Porter Equipment Company v. Basketball Products International and Ehrat, 1984
Civil action, April 1984-June 1984: The complaint alleges that Ehrat's and Basketball Products International's patents are invalid and unenforceable and that Porter and Mt. Vernon School District did not infringe. Porter calls for dismissal or transfer of the case. The pleadings index for Vol. 1 has a note at the bottom that says "Start Vol. 2," but Vol. 2 is not in the collection.
Subseries 3: Gared Company v. Basketball Products International and Ehrat, 1984-1988
Civil action, March 1984-October 1984: This action is in response to letters sent by attorney McPherson Moore threatening a lawsuit if Gared Company does not cease manufacture of infringing goals. Gared Company files a complaint for declaratory judgment, calling the patent invalid and alleging unfair competition. A stipulated dismissal of complaint was signed by Moore and Ralph Kalish, Gared Company's legal counsel. Declaratory judgment is the judgment of a court which determines the rights of parties without ordering anything be done or awarding damages.
Of note in this subseries is the deposition of Ehrat regarding his involvement with Gared Company and the city of St. Louis, where the company is based. Gared Company's counsel, Ralph Kalish, asks Ehrat questions about his nephew, Randy Albrecht. Ehrat purchased 12 rims from Gared Company, on the advice of his nephew, for the purpose of building and testing his releasable basketball goals. Kalish tries to assess whether there was a profit motive and how Gared Company's goals factored into that.
Subseries 4: Basketball Products International and Ehrat v. Gared Company, 1984
Civil action, April 1984-June 1984: Complaint filed against Gared Company and Athletic Supply (which purchased Gared Company goals) for patent infringement. The case was dismissed.
Subseries 5: Basketball Products International and Ehrat v. Toss Back
Civil action, May 1984-June 1984: Complaint filed against Toss Back and the cities of Seattle and Tacoma (which purchased Toss Back basketball goals) for patent infringement. There is no evidence of a settlement or of court action. Toss Back signed a licensing agreement with Ehrat in 1985 (See Series 4, Licensing Agreements).
Subseries 6: Ehrat v. Gared Company and Nixdorff-Krein Industries, 1982-1990 (bulk 1987-1990)
Civil action, 1988-1990: Complaint filed against sports equipment company Gared and its parent company, Nixdorff-Krein Industries, for patent infringement. Request for passing case for settlement filed by Ehrat's attorney, McPherson Moore, and granted by the court. The signed settlement is in this subseries. This subseries has file histories of Gared Company patents. A file history (or file wrapper) is a folder kept at the United States Patent and Trademark Office that has all of the correspondence and documents from a patent application
Subseries 7: Ehrat v. Diversified Products, 1989-1994
Civil action, 1993: A complaint was filed against Diversified Products after a series of letters calling for the company to cease manufacture and sales of infringing basketball goals went unheeded. The parties were granted a consent judgment to settle out of court. The signed settlement is in this subseries.
Subseries 8: Ehrat v. Icon Health & Fitness Inc., Pro Form Fitness Products Inc., and K's Merchandise Mart, 1984-1996 (bulk 1994-1996)
The Icon Health & Fitness Inc. (hereinafter Icon) pleadings consist of two volumes, Vols. 2 and 3. Vol. 1 is missing. There is a draft of the first page of Ehrat's complaint against Icon in Box 9, Folder 3. A consent judgment was entered, and the parties settled out of court. The signed settlement is in this subseries.
There are two categories of production documents in this subseries, those for the plaintiff (three folders) and those for the defendant (seven folders), that have Bates numbers affixed to or printed on the bottom of the pages. Bates numbers are used to identify documents with a unique number. The parties to a lawsuit use these numbers to keep papers in order when they are sent to the other party during discovery.
The plaintiff's production documents include Bates numbers 1-205. Numbers 1-105 contain Ehrat's patent file history; numbers 107-205 are copies of Ehrat's licensing agreements through 1993.
In the defendant's production documents, one folder has Bates # I10001 and other numbered pages that are not in a particular order. Bates numbers I10068- I10882 include the file history for United States Patent No. 4,365,802, deformation-preventing swingable mount for basketball goals; correspondence among defendant's attorneys; copies of patents; and copies of licensing agreements through 1993.
Series 4: Licensing Agreements, 1982-2000 (bulk 1980s-1990s)
This series is divided into twenty-six subseries and encompasses materials pertaining to Ehrat's relationships with numerous companies that manufacture or sell sports equipment. These materials include correspondence and notes, licensing agreements and drafts of agreements, Dun and Bradstreet financial reports, catalogs, pamphlets, and other promotional materials. Ehrat and attorney McPherson Moore used the promotional materials to determine whether the companies were marketing or selling basketball goals that infringed on Ehrat's patent, then contacted the companies about licensing Ehrat's patent. With the exception of Subseries 1: Correspondence and Subseries 6: William Dittrich Patents, each subseries represents a different company.
To better understand Ehrat's relationships with these companies, researchers should consult Subseries 1: Correspondence, as well as the correspondence within specific subseries, in conjunction with licensing agreements and other documents in this series.
There are thirteen signed licensing agreements in this series, some of which bear original signatures. Ehrat's first licensee was with Basketball Products International, which signed an exclusive agreement in 1983. In November, 1984, after five civil action lawsuits in which Ehrat and Basketball Products International were either co-plaintiffs or co-defendants, the company signed a nonexclusive licensing agreement. Drafts of the agreements exist for some companies, but there is no evidence that the agreements were signed. In some cases, correspondence indicates which companies were not interested in entering into an agreement.
Ehrat's licensees include Huffy (signed May 1988); Basketball Products International, exclusive license (signed July 1983), nonexclusive license (signed November 1984); Toss Back (signed January 1985); Porter Equipment Company (signed 1985 and 1989); RDH Enterprises/Schutt (signed August 1991); Industrial Machine Specialties/Bison (signed January 1987); Lifetime Products (signed March 1989); Fisher-Price (owned by Quaker Oats, signed April 1988); Indian Industries/Harvard Sports (signed June 1991); McCullough (signed April 1990); and Sure Shot (signed March 1991).
Companies in this series without signed licensing agreements include Medart; Blazon-Flexible Flyer; Spang/Today's Kids; Sports and Leisure/Ideas That Sell; Wilson Sporting Goods; Hutch Sporting Goods; Aalco; Bergfeld Recreation; Future Pro; MacGregor; Pro-Bound; Architectural Design Products; and Hyland Engineering.
Settlements and licensing agreements that Ehrat signed with Gared Company, Diversified Products, and Icon appear only in Series 3, Civil Action and Settlement Records.
Subseries 6, William Dittrich Patents, contains correspondence and documents relating to the patent and royalty agreement Dittrich made with Ehrat in 1987. Dittrich had two basketball-related patents but had difficulty getting companies to license with him because there was confusion about his patents and those of Ehrat and Frederick Tyner. Dittrich contacted Ehrat's attorney, McPherson Moore, and they worked out an agreement. Ehrat acquired Dittrich's patents and they joined forces to attract licensing agreements and to split royalties and litigation settlements. Subseries 6 also has the transcript of a 1986 phone conference between William Dittrich and McPherson Moore regarding a possible joint agreement with Ehrat and the patent file history for United States Patent No. 4,151,989, basketball practice device. There is no file history for Dittrich's other patent, United States Patent No. 4,465,277, basketball goal structure, but there are pieces of the file history in this subseries. Subseries 6 also includes drafts and signed patent assignment papers and a signed licensing agreement between Ehrat and Dittrich, 1987.
Subseries 9, Lifetime Products, consists of itemized lists of attorney's fees from McPherson Moore for November 30, 1987, to February 28, 1989. The fees are for research, phone calls, photocopies, correspondence, and litigation documents for Ehrat v. Gared Company. The companies listed in these papers include Gared Company, Lifetime, Huffy, Fisher-Price, Sports and Leisure, Today's Kids, Toss Back, and Blazon.
Subseries 16, McCullough contains a Dunk-Kit (see Box 18), which Ehrat purchased in 1989. The Dunk-Kit is a set of springs and bolts that turn a set basketball goal into a breakaway goal. According to attorney McPherson Moore, the springs and bolts constituted an infringement of Ehrat's patent. McCullough disagreed with this assessment but eventually agreed to a monetary settlement.
Series 5: Field Spreader Patents and Other Ideas, 1977-2003
Subseries 1: Field Spreader Patents, 1977-2003
This subseries contains copies of Ehrat's two field spreader patents: United States Patent No. 4,358,054, field-sprayer tank-vehicle having means for on-site metering and mixing of soil-treating chemicals and United States Patent No. 4,588,127, material-spreading field vehicle having means for on-site metering and mixing of soil-treating chemicals. It also contains magazines, articles, and pamphlets on agricultural equipment and litigation documents between SoilTeq and Ag-Chem.
Subseries 2: Other Ideas, 1971-1998
In the late 1980s and early 1990s, Ehrat came up with ideas for other inventions, but none of them were patentable. This subseries has original sketches for "electric clippers with box for holding clippings;" a beverage can with multiple containers; and an "automobile refreshment temperature control." Included in the folders are letters that outline the ideas behind the inventions and the reasons they were not patented. Also included are copies of patents that relate to Ehrat's ideas.
Series 6: Toby Dittrich Files, 1889-1997
This series, which is further divided into five subseries, contains administrative records, prior art, patent records, correspondence, litigation materials, financial records, marketing and sales materials, photographs, and newspaper clippings from William A. (Toby) Dittrich. Dittrich invented the "Dunk King" break-away basketball rim in the mid 1970s while he was a physics professor at Pacific Lutheran University in Washington State. Dittrich patented and marketed his rim with mixed success before selling the rights to his patents to Arthur Ehrat in the mid 1980s. The two agreed to market and license their products independently, and cooperatively share royalties and settlements from patent infringement cases.

Biographical / Historical:
Arthur Henry Ehrat was born December 20, 1924. He grew up on a farm near Shobonier, IL, east of St. Louis. Ehrat had four sisters and a brother: Dorothea, Ruth, Bernice, Grace and Walter. Growing up on a farm during the Great Depression, Ehrat learned farming skills, including milking, baling, and operating heavy equipment such as threshing machines. After graduating from Vandalia High School he moved to Wheaton, IL, to work on a farm. From the latter part of 1945 until 1947, Ehrat was an Army medic, stationed in Fort Sheridan, IL; Camp Atterbury, IN; Fort Meade, MD; and Manila, Philippines. After his Army service, Ehrat moved back to Illinois and spent a few years farming with his brother.
In the early 1950s Ehrat lived with his sister Bernice and her family in Minneapolis while attending a two-year course at Minneapolis Business College. Upon completion of the course, he returned to Virden, IL and worked at a grain elevator. Ehrat met Mary Mardell Worth in Virden. They were married June 27, 1954, and had five daughters: Rose, Jo, Sharon, Jane and Linda. Ehrat managed the grain elevator at Farmers Elevator Co. in Lowder, IL for nearly 30 years.
In the mid-1970s, Ehrat's nephew, Randy Albrecht, a coach at St. Louis University, mentioned that basketball players were slamming the basketball ball through the rim and hurting themselves, as well as bending or breaking the rims, which were affixed directly to the backboard. The bent rims had to be straightened, causing a delay of game. While Ehrat never had a strong interest in the game of basketball, Albrecht suggested his uncle, who was known as a tinkerer, come up with a safer basketball rim. The conversation sparked a few ideas. Ehrat bought a flimsy $20 basketball rim and began building a prototype.
Basketball fans during the 1940s and 1950s didn't see many slam dunks. Despite the leaping ability of stars Bob Kurland, George Mikan, and James Clifford Pollard, aka "the Kangaroo Kid," the dunk shot was considered showboating and was often done only in practice. Basketball players, whose average size was smaller in the mid-20th century, viewed the dunk as a low-percentage shot compared with the ubiquitous jump-shot.
In 1967, the National Collegiate Athletic Association (NCAA) outlawed dunking. A few years later, Julius "Dr. J" Erving, who played professionally for the American Basketball Association's Virginia Squires, re-ignited excitement about basketball with his high-flying slams. In the first half of 1976, a few months before Ehrat first applied for a patent, the dunk was reinstated in college basketball.
At the professional level, flamboyant hoops star Darryl "Dr. Dunk" Dawkins shattered some glass backboards in the late 1970s and early 1980s, which prompted the National Basketball Association (NBA) to ban the shattering of backboards and make collapsible rims mandatory. The NBA's call for collapsible rims, along with the NCAA's reinstatement of the dunk, opened the door for innovations in basketball rims.
Collapsible rims, which folded down when pressure was applied to them, were the precursor to breakaway rims and had to be manually put back in place. Ehrat created a safer basketball rim that automatically snapped back after a slam dunk.
Ehrat's first rim, used a door spring. It was bolted to two plates, one that remained fastened while the other flexed down under pressure. The hinge was not strong enough, so he focused on creating a detent. A detent is a device that holds one mechanical part in relation to another so the device can be released when force is applied. If someone slam dunks a basketball and pulls on the rim, a detent would allow the rim to flex downward with minimal pressure on the backboard. Ehrat fitted some heavy-duty magnets between metal plates on the rim, but this did not work as he envisioned.
The turning point came when Ehrat decided to use a spring mechanism. Drawing upon his agricultural background, he pulled a spring from a John Deere cultivator, cutting it to fit the basketball rim. The thick, sturdy coil was able to withstand more than a hundred pounds of pressure before yielding downward and would push the rim back into place. In addition to the spring, he tested ball bearings, bolts, and corner braces before finding the right combination that would hold at least 150 pounds of pressure.
Once he had viable prototypes, Ehrat tested their durability. He sent one to Virden High School and enlisted Randy Albrecht, to test the other prototypes. Albrecht used his connections as a basketball coach at St. Louis Community College at Meramec to have prototypes installed at the schools where he worked. The rims were sent to other high schools and colleges by Ehrat. For more information on where the prototypes went, see his deposition in Series 3, Subseries 3. Ehrat estimated in his deposition that he built approximately 36-40 prototype rims.
It took six years, from July 1976 to December 1982, for Ehrat to receive the patent on his basketball goal (United States Patent No. 4,365,802, Deformation-preventing swingable mount for basketball goals). His application was rejected twice, with patent examiner Paul Shapiro noting that Frederick C. Tyner held a patent for a similar basketball goal (United States Patent No. 4,111, 420, energy-absorbing basketball goal/backboard unit).
Ehrat and his attorney, Ralph Staubly, pursued an appeal of the rejection. Staubly, a retired patent examiner had moved to Springfield, IL, in the 1970s to open a private practice. A major part of the appeal involved notarized letters from acquaintances who said that Ehrat's invention was unique and would be an asset to the sport of basketball. He also proved, through copies of canceled checks and a rough sketch of his invention, that he was working on his breakaway basketball goal in 1975 before Frederick Tyner conceived of his. In a 1984 deposition (Series 3, Subseries 1), Tyner placed the date of his invention near the last week of March or first week of April 1976, not long after he heard that the NCAA had reinstated dunking.
Ehrat won the appeal, effectively rendering the Tyner patent invalid. After Staubly fell ill and moved to Texas, and in early 1983, Ehrat found a new patent attorney,McPherson Moore of the St. Louis firm Rogers, Eilers and Howell, who became Ehrat's main legal counsel for approximately 20 years.
In February, 1983, two months after Ehrat received his patent, his attorney McPherson Moore sent certified letters to more than 60 sporting goods companies to announce the patent. The letters were sent to alert companies of possible infringement and to garner interest in licensing agreements.
During the basketball goal patent's 17-year lifespan, Ehrat obtained a dozen companies as licensees. Only Fisher-Price and Schutt Manufacturing signed without much difficulty. Ehrat worked to get the other companies licensed, in some cases filing patent infringement lawsuits or threatening to file them. Ehrat's first licensing agreement, signed in 1983, was with Basketball Products International.
Ehrat was involved in eight civil action lawsuits, five of which took place in 1984, when he had to prove for a second time that he had his idea for a breakaway goal before Tyner. Ehrat also defended his patent against other, similar patents issued to sporting goods companies in the early 1980s. Kenneth Mahoney of Toss Back, Charles Engle of Gared Company, and the Porter Equipment Co. all received patents for basketball goal devices, citing Ehrat's patent as prior art. Ehrat was involved in lawsuits with all three companies.
In 1986, Ehrat and attorney McPherson Moore were contacted by William "Toby" Dittrich, who held two patents --United States Patent No. 4,151,989, basketball practice device and United States Patent No. 4,465,277, basketball goal structure. Dittrich was having difficulty licensing his patents to companies because of the confusion over Ehrat's and Tyner's patents. Dittrich assigned his patents to Ehrat in 1987 and they signed a joint licensing agreement to split royalties and settlement money.
In addition to his basketball goal patent, Ehrat also holds two patents for agricultural inventions: United States Patent No. 4,358,054, field-sprayer tank-vehicle having means for on-site metering and mixing of soil-treating chemicals; and United States Patent No. 4,588,127, material-spreading field vehicle having means for on-site metering and mixing of soil-treating chemicals.
Arthur Ehrat died on July 9, 2015.
