Hi Ruud,

Thanks for your very interesting report.

The term "intellectual property" is usually used to refer to copyrights,
trademarks and patents.  Let's see: copyright covers only the expression of
creative works.  I don't think that the interface pinouts can be covered by
copyright.  Trademarks could apply, e.g., your can't sell a product called
"Commodore 64 hardware interface" without having permission from the trademark
owner.  But the name IDE64 should be okay.  Finally, yes, the interfaces could
be covered on patents.  If any were filed, they would have been filed in the
very early 1980s at latest, and thus the expiration time of 17 or 20 years must
have already passed.

Of course, the new C64 (built inside a joystick) can be a different matter,
if its circuit board design is covered by a patent.

It should be noted that Commodore didn't own the rights to most games.
But Ironstone probably has agreements with other copyright holders, including
at least the current owners of Epyx copyrights, if a previous announcement
I read about a re-release of Summer Games, Winter Games etc. is correct.
