Infringement



Infringement is the unauthorized making, using, or selling for practical use or for profit an invention covered by a patent. Effective 1996, GATT also made the offer to sell a patented invention without the permission of the patentee a direct infringement violation.



Although no infringement can occur before a patent is issued, infringement can occur even if the infringer does not have any actual knowledge of the existence of a patent. A direct infringer is one who makes, uses, or sells the patented invention without permission from the patentee. An indirect infringer is one who actively encourages another to make, use, or sell a patented invention without permission. A contributory infringer is one who knowingly sells or supplies a part or component of the patented invention to another, unless the component is a staple article of commerce and is suitable for a substantial noninfringing use.

The definition of an infringement, provided in 35 U.S.C.A. § 271, has been greatly expanded in the late 1980s and 1990s. For example, it is an infringement to apply for federal FOOD AND DRUG ADMINISTRATION approval of a patented drug if the purpose is to obtain approval to manufacture, use, or sell the drug before its patent expires. It is also an infringement to provide a substantial portion of the components of a patented invention to someone outside of the United States so that the components can be assembled outside of the reaches of U.S. patent law. Similarly, it is an infringement to import into the United States a product made by a process covered by a U.S. patent although it was produced outside the United States.
