What do you think that Plato or Socrates would have though of this? I would never attend a class conducted by someone who had decided that ideas were his, and his alone.
Do I think that it's right to be able to copyright a plan, or an object? Absolutely. But an idea? An undefinable, ethereal image of a dream! How can one learn and grow if all ideas are owned?
Just another step in the ever-advancing corporatism of the modern world.
