The base ideas of a home video game console were developed by Ralph H. Baer while working at Sanders Associates, where in 1966 he began work on what ultimately became his "Brown Box" prototype. After securing approval of a proposal for his idea from his superiors, Baer worked with Sanders engineers Bill Harrison and Bill Rusch to execute its design while keeping it within a low cost target. By 1967, the optimized design was ready to be shopped to other manufacturers as Sanders was not in that market area. To protect the idea, Sanders applied for and received three patents in Baer's, Harrison's, and Rusch's names, covering their "television gaming apparatus"; this included the 1974 reissued U.S. Patent RE28,507 for a "television gaming apparatus", U.S. Patent 3,659,285 for a "television gaming apparatus and method", and U.S. Patent 3,728,480 for a "television gaming and training apparatus". Sanders eventually licensed the technology and the patents to Magnavox, which used it to make the Magnavox Odyssey, released in 1972. In 1974, Magnavox sued several companies creating and distributing table-tennis arcade games including Atari and Midway. This case was ultimately decided in Magnavox's favor in early 1977. Atari settled before the final judgement and agreed to pay Magnavox for a perpetual license to the three patents and other technology sharing agreements.
