- Very few inventions in any field are solely the work of the inventor. An
- inventor builds upon past design and practice, adds something he came up
- with himself, and produces something novel. He can then patent the part he
- came up with, and anything that incorporates that component is subject to
- the patent.

-
- Other people writing about an invention after the fact doesn't affect the
- validity of the patent. Would these articles have been written at all if
- R, S, and A hadn't published the design of their encryption system in the
- first place? Patents exist to encourage publication, which then encourages
- others to comment and build upon the invention.

-
- Some people believe that patents in general are morally wrong, because they
- legally permit a patentholder to prevent an inventor from using the fruits
- of his labor. Independent invention is not a valid excuse for infringing a
- patent.
