This is not correct. If someone invents the bottomless soap dish and patents it, then anyone who makes, uses, or sells bottomless soap dishes is liable for infringement. On the other hand, if someone invents a new way of curing rubber and patents it, then there's no way to infringe the invention by making or selling it. You can make rubber, and you can make cured rubber, but how do you make the *process* of curing rubber? That doesn't make sense. The only way to infringe a method patent is to use the method. ---Dan
