A patent owner may enforce the right to exclude others from making, using, or selling the patent invention in an action for patent infringement. Anyone who, without the owner's consent, makes, uses, or sells in the United States any product, process, apparatus or composition that is legally protected by at least one claim in the owner's patent is liable for direct infringement of the patent.
A person may directly infringe a patent without knowing of the patent or intending to infringe it. Good faith is not a defense to a claim of direct infringement. 35 U.S.C.
