Many technologies have both patented parts and trade secret parts. Often,
companies will maintain information that is in patent applications as trade
secret until they are granted. I guess I should say _if_ they are granted!
After a patent is granted, it is usually a good idea to also maintain some
trade secrets in your products -- since trade secrets never "expire," unlike
patents. If the patent isn't granted, you still have the option of treating
the contents as an intellectual property under trade secret protection.
