In the court case between M$ and Lindows over the use of the term Lindows, M$ loses the first round:

The Register: Window v. Lindows - round one to underdog

The ruling raises some interesting questions for M$ in general:

...the Court finds that Lindows.com has met its burden of proof in rebutting the validity of the Windows trademark... Microsoft counters Lindows.com's evidence of genericness with only sparse support for its claim that Windows falls into a protectable category. Microsoft supplies minimal affirmative evidence to support its claim that Windows is non-generic
from page 20 of the ruling ...

It's nice to see some objective rulings ...
