[luau] NEWS: Can Microsoft Patents Stop Open Source File-Sharing?

[W. Wayne Liauh]

Nowadays, patent claims are very narrowly construed.  Furthermore, that 
fact that you have a patent doesn't necessarily mean that it is 
enforceable or even valid.  Current stats are more than fifty percent of 
the issued patents are held invalid by the court.

Several years ago, I had a chance to review Microsoft's patent 
portfolio.  Most of them were very weak and I don't think they can stand 
in court.
