> I thought you were going to say Informix... Ah yes.. The story about Informix was that IBM negotiated for x-licensing, but Informix decided they didn't need to. So IBM sued and Informix counter-sued (of course)... the rest is known. Patents are like nukes, lots of sabre-rattling. Usage is last choice. Problem is that there are also a lots of duds because the patent lawyers haven't got a clue, so most anything gets patented unchecked. But testing the validity of a patent is expensive and dangerous (if upheld). That's why they have these funny stacks of claims: Claim 1: This patent covers teh meaning of life. ...
Claim 99: This patent covers something noone cares about.

A carefully laid out minefield ...

Cheers
