I have zero tolerance for infringers and have made enough for a couple of nice cars (at least) from pursuing infringers. But you MUST have a knowledgable and experienced attorney handle the entire thing and a good, honest lawyer will tell you if you have a case or or not. He'll also tell you, as a defendant, when you must fold. Fortunately, I've never been a defendant and have never folded as a plaintiff.
There is one caveat to add, however. Unless I'm mistaken, there is language in the statute that if you are aware of an infringement and don't pursue it, you are essentially abandoning the property. That certainly doesn't apply in the sited article (am I misinformed.
Pursuit also becomes more of an issue when you're dealing with infringements overseas, where the costs can be prohibitive and the return not worth the effort. All that said, recordings of performers, as well as recordings lifted from CDs or DVDs, etc., are
much easier to pursue than an "it sounds like music I wrote" kind of action.
I'm glad they nailed this guy.
