The Open Group own both the UNIX trademark and the POSIX spec. They used to demand a lot of money for copies of the spec, but you can get it online for free nowadays ( https://www2.opengroup.org/ogsys/catalog/G101 https://www2.opengroup.org/ogsys/catalog/G101 is a good place to start). They put copyright notices on the spec, but (at least until this ruling) that was widely believed to only apply to the description of what functions needed to do, and not to the function declarations.
- stormbrew 12y agoIs it clear that The Open Group or IEEE actually have a clear right to claim copyright of the POSIX api given this ruling? Were they assigned or licensed that copyright by AT&T or any of its successors? It seems likely enough that in the 80s this was not seen as necessary, and the old guard of UNIX implementers were still being quite belligerent towards each other at the time, afaik.
- maxlybbert 12y agoI believe the Open Group was assigned whatever copyright AT&T had when the Open Group was created.
