They have pathented the usage of certain mathematical operation to implement a communication system. That is, anybody is free to use modular arithmetic in general, but usage of modular arithmetic for encrypted and/or authenticated communication is patented. > Has this patent yet been challenged in court? It seems Nope. RSA/PKP has filed a suit once or twice, but that matter was always settled outside the court. > to me that it would be like trying to patent the Pythagorean > Theorem. You are free to patent anything, if you succeed to convince the patent office experts that this is something new.
