IANAL, but to me it sounds like patent trolls can now patent stuff other people invent, then sue the inventor.

"The measure would switch the United States from the "first-to-invent" system to the "first-inventor-to-file" system for patent applications."

The stuffs an inventor created would become prior arts. Patent trolls filing after seeing the invention would get its patent invalidated.

This doesn't change much with respect to prior art afaik.
