They're referred to in the industry as patent trolls.

I think patent trolls are abusing the system.

The cause of the lawsuit is not that we are patent trolls. The cause of the lawsuit is that these defendants used our patented technology to make over $1.5 billion in revenue.

Aside from the mythology involved, one way to look at the troll situation is that you have 'bad patent trolls,' on the one hand, and 'bad patent thieves,' on the other.

Trolls suck.

Certainly it constitutes bad news when the people who agree with you are buggier than batshit.
