Hi,
The peril of patents on software...

"A company called Lagos Analysis Corporation has sent out a press
release announcing a patent infringement lawsuit against the One
Laptop Per Child project. "The patent infringement lawsuit was filed
on November 22nd, 2007 as a result of OLPC's willful infringement of
LANCOR's Nigeria Registered Design Patent #RD8489 and illegal reverse
engineering of its keyboard driver source codes for use in the XO
Laptops." The patent text is hard to find, but it seems to relate to
the design of keyboards which facilitate the typing of text in
multiple languages."
