That was a concept patent.
When did it get fleshed out and produced? Who helped.
The foundational patent for the modern transistor was filed in the U.S. in early 1948 and officially granted on October 3, 1950 to Bell Labs scientists John Bardeen, Walter Brattain, and William Shockley.Here is a quick timeline of the transistor's patent and development history:December 1947: The very first working transistor (the point-contact transistor) was successfully built and tested at Bell Laboratories.February 26, 1948: The first patent applications for the point-contact transistor were filed.June 26, 1948: William Shockley filed the original patent for the improved "junction transistor", which was later issued as US Patent #2,569,347 on September 25, 1951.October 3, 1950: The U.S. Patent Office officially issued the earliest patents for the Bardeen, Brattain, and Shockley transistor designs.
