Yes.
Another example is the LOGO language as implemented on Plus/4. The manual states:
"LOGO Programming Language (C) MIT. 6502 implementation (C) Terrapin. Plus/4 version by (a list of Commodore and Terrapin employees)."
In this case, Massachusetts Institute of Technology students developed LOGO, then they moved on to form Terrapin. Terrapin can claim copyright of LOGO on systems that they wrote after they left MIT, but the actual language (keywords, structure) is still owned by MIT. Commodore licensed LOGO for their 6502-based machines and had the right to modify as necessary to work on current and future machines.
(The LOGO Plus/4 manual mistakenly states that the LOGO Language disk cannot be CATALOGued, when in fact the 64 version came on diskette, the Plus/4 version on ROM cartridge. The Plus/4 manual is simply the 64 version manual and a simple search-and-replace done to change 64 to Plus/4.)
