You'll find infos about the XOR patent and several other patents at
http://www.ipcreators.org/Heckel/ACM%20Paper/acmpaper.htm.

Many more links on XOR you can find on the www.google.com search engine
(just enter "XOR patent")

Kind regards
Ingo

Hi,

someone holds a patent on XOR on graphics.

So you couldn't draw a selection frame with your mouse in Gimp
without violating this patent. You would have to "enjoy" flickering like
Sinclar ZX81 or enter the corner coordinates via keyboard.

I would like to accentuate that Open Source is innovative officially:

See http://www.rtlinux.org/rtlinux.new/documents/faq.html
http://www.linuxdevices.com/news/NS5405878763.html
http://slashdot.org/articles/00/02/10/1048214.shtml

Excerpt:

"The basic mechanism that makes RTLinux work is protected under
U.S. Patent 5,995,745 and is freely licensed to RTLinux users for
commercial and non-commercial purposes as described below."

Regards,
Ingo
