I didn't think that it mattered if there was prior artwork which was only known to a few people. If this were the case, most patents could be contested because most inventions are "re-invented" by several people and only one or a few ultimately decice to pursue it and get a patent. Interestingly enough, I do know that it is possible for two patents to overlap and therefore, unless the two patent owners work together, neither can produce their idea.
