Whole hosts of people who specialize in various fields go on to law school and become patent lawyers or judges, and with all the applications and lawsuits, they're needed. However, it's a field that most of us know every little about, though we should. For instance, living organisms and cell lines have been patented.
In "Intellectual Property: Silly or Sinister," David Levine writes about the absurd level to which patent production has sunk. Then again, Levine says the system itself is and always was "abusive by its very nature."
I'd like to know what everyone thinks of Levine's article. In the meantime, I've got to get going on an invention that no one else has thought of, something better than a warp drive.
