The common wisdom at Burroughs when I worked there in the 80s was that back in the 60s and 70s, Burroughs often invented something, then 5 years later IBM would "invent" it, and then the industry press would start talking about what a good idea it was. I still have next to my desk a small sign I salvaged from the computer room in the Burroughs Pasadena Development Center when it was being shut down, which reads "Each person having access to this room is cautioned not to discuss the machines or work done here with unauthorized employees or persons outside the company. Premature disclosure of new inventions might void our patent rights here or throughout the world." (signed by the then-president of Burroughs, R. W. Macdonald) I saved it because the irony amused me at the time.
