The only official disclosure of the Propeller firmware has been the ROM source code for which Parallax Inc holds the copyright.
What are the copyright implications (if any) for third party tools that compile/assemble for the byte code interpreter?

The interpreter will just run the byte codes it sees. How those byte codes are realized is an open discussion at this point.

Parallax doesn't own the copyright on the byte codes. They have the copyright on the bootloader and the interpreter which are programs and can be copyrighted. The byte code functionality was a trade secret of Parallax's and it was independently decoded and described by individuals working with publicly available information, namely the compiled output of the Propeller Tool (another trade secret program) when fed programs written by these individuals.
Thanks Mike!

If there is any rights to the bytecode (I am not a lawyer) and your use is for the benefit of Parallax I don't believe there will be any problems. I would presume this includes the Gear simulator, as this still benefits Parallax.
However, if you wanted to use them in another processor, then maybe there would be implications to this.
