The second possibility instead of avoiding the patent is to get a license for the patent. This is not necessarily an option. The patent holder does not have to offer you a license, it is not required. 10 Years ago, the league for programming freedom got a letter asking for help from somebody whose family business was making gambling machinery for casinos and they used computers back then. He received a threat from another company that said we have the patents. You are not allowed to make these things. Shut down.
