Since patents are generally very vague in order to encompass as much as possible of a given market, the significant changes would have to create a whole new product and thus a whole new patent. You would be still able to use the old expired patent to your hearts content. If they could have done it, they would have. A few publications did some stories on RSA - mainly Bidzos - and where he was planning to take the company once their nest egg expired. Anyhow, according to RSA[1] they were issued the patent on September 29, 1983. However, according to the IBM[2] and USPTO server they are listing the issue date as September 20, 1983. Using the USPTO and IBM servers as a reference, the patent officially expires on September 20, 2000.
