If you do trademark or patent something it helps if you open a company with that name too.
For example start a company called Parodee Videos and trademark it. You can then start sueing people who use the word Parody Video in their video titles, as it sounds like Parodee. Heck you don't even have to sue, if you stick to Youtube because it's a super easy target for IP trolling, all you have to do is claim ownership and monetize it. I think as a right holder you can choose if it gets taken down or if it stays, but you monetize it.
Actually this is sounding like a good idea, scratch that... let me go register my company...I THOUGHT OF IT FIRST!
You can also just patent trivial stuff that people did not think of patenting. Drones are all the rage right now, so patent the concept of counter spinning propellers, because most quad copters have props that turn in an opposite direction as the other. I think it helps stabilize it. I doubt any of the major drone makers have thought of patenting that, because it's just so trivial. you can also patent shapes, a lot of drones seem to have the same look as the Phantom. So patent that shape. It worked for Apple. (rounded corners)
You need lot of money to get started though. Patents arn't cheap. So you either take a loan and risk that it does not work, or you get some rich investors involved.
The more I think about it, the more I think we actually need more IP trolls. If there is enough of them maybe the government will actually do something about it and revamp the system when it starts to affect even big corporations.
