Not always. There could be patent applications that have been out before 
you posted. But what you want is not to be on the defensive side only. If 
a company comes and attacks you over a patent they own, you pull out all 
your patents and look to see if the company that is attacking you is using 
anything you own.

As I said, the more patents that the Open Source community owns the 
better. The Open Invention Network is posed to counter attack any company 
that tries to attack a free software group. It is not just to counter with 
prior art, but also threaten the company that is attacking.
