The patent wars rage on. Eolas, a company that before won US$585 million from Microsoft in 2003 in a suit that challenged the use of ActiveX and AJAX, is now after twenty-three separate companies allegedly because their precious patent was spoiled by all of them.

Incorrect. You are thinking about Trademarks. Patents do not have to be enforced to remain enforceable. That's where the term "submarine patent" comes from - someone patents something, then waits and does nothing while companies implement products using the patented idea. When it becomes big enough, THEN they surface and sue everybody.
Some companies have even gone so far as to pretend that it's okay to use their patents, then turn around and sue over them once they become popular. "
Incorrect on your part. There is a time limit for how long someone with a patent can wait before enforcing it. This is where the submarine patents come in - the patent holder waits until nearly the last minute then provides notice of court filings.
You are correct that Trademarks hold the same; as do copyrights. Though the terms vary for each.
In all cases the clock starts at the time the 'owner' becomes aware of the infringement (copyright/patent) or unapproved use (Trademark).
