It is not uncommon to have a product that is both covered by a patent and potentially infringing of another’s patent. A classic example is to think of two patent holders, one who owns the patent for a stool and another who owns the patent to a chair. In this hypothetical situation, the “chair” is just a back support attached to a stool. The person wanting to sell the chair might have a patent covering his or her improvement to the stool, but that person would need a license to the stool patent if he or she wanted to sell chairs on the market.
