Patent Anecdotes and Other Stories

Why the original Bell Labs/Shottky transistor patent application, though worthy of a Nobel prize, was rejected over this early patent with Canadian priority.

As it turns out, Lilienfeld, though an unknown Silesian immigrant, had been a student of Arnold Sommerfeld before he settled in Massachusetts.

Shottky and his team at Bell Labs did go on to get a patent for the transistor, but with reduced claim scope.

Albert Einstein (a former Swiss patent examiner) prosecuted this U.S. patent, directed to an ammonia refrigerator, pro se. He and Leo Szilard were co-inventors.
