The real problem is that patents are worthless. The reason they are worthless is that the Patent Office stopped requiring working models in the 1970s--claiming they had no more warehouse space to house the models.

With the working-model requirement gone, it is easy to patent violations of Newton's Laws of motion, etc. Heck, they may even allow violations of the Laws of Thermodyanmics.

U.S. Patents are trash because the 'examiners' can be easily hoodwinked. Sometimes I think none of them took Physics 101...
