I assume that this is a perfectly fine situation with the FSF.

For copyright, if you don't prosecute violations promptly, then you
lose the right to prosecute that violation at all. (I believe the
technical term for this is "laches", and it applies to just about any
Selective copyright enforcement is perfectly fine; it's just that if
you fail to enforce against John Doe, you might lose the right to
enforce against him at all. But it's perfectly fine to prosecute John
Doe but not Mary Roe, and you have complete discretion.
For patents, it's even more liberal: laches never applies to patent
violations. So even if you let John Smith get away with it for five
years, you can still come and sue later. There's an explicit
provision in law against any kind of "squatters' rights" in the case
of patents, alas.
