If they actually have a strong case it will be highly unlikely 
that you have arrived at it independently. Of course, all you 
have to do is to remove the code and FSF will be happy. So if you 
let it go all the way to the court you can only blame yourself 
for being pedantic.

FSF will only sue over a strong case that carries political 
weight. A loss in court is a PR disaster for FSF.

Iff you use it as a means for production. There is nothing 
illegal about implementing patented techniques in source code 
(i.e. describing them) and distributing it.

If that is the case then there will be prior art that predates 
the patent.

It should help you, not hurt you, if you learnt about a technique 
from a widespread codebase from an organization that is known for 
avoiding patents. If anything that proves that you didn't pick it 
up from the filed patent and was in good faith?

If the case came to light (e.g. you knew about it) and you didn't 
vet your own codebase then you will be to blame no matter where 
you got it from? But FSF would make sure they remove patented 
techniques from GCC so that scenario would be very unlikely.

In other words, you are more likely to be hit by a bus when 
crossing the street. I find this kind of anxiety hysterical to be 
honest. The only thing I get out of this is that companies 
shouldn't admit to using open source codebases.

Of course, one reason for avoiding reading other people's source 
code is that you have a client that makes it a requirement.
