Something else that comes to mind involves the PC BIOS.

Years ago some companies decided to create BIOS emulators.
Phoenix for instance.

When hiring engineers to create the BIOS code, the candidate engineers
had to be interviewed by attorneys to ensure that the engineers were
'virgin', that is, they had never had any involvement with IBM BIOS,
and had in fact never even seen the code.

Producing a BIOS that emulated IBM's was legal under these conditions,
as they were not reverse engineering the code, but producing new code
that emulated the behavior of the IBM BIOS.
