Patent Law Research Guide. This guide focuses on one area of intellectual property law, patent law, and provides an introduction to key resources for conducting patent law research at Georgetown.
A patent means a property right granted by a government agency. A land patent is an official recognition of a claim to a defined piece of real estate. An invention patent is an official recognition of a claim to an invention. It does NOT grant any inherent rights: it grants the right to exclude OTHERS from making, using, selling or importing the claimed invention for the duration of the patent validity. If the patent uses inventions that are claimed by others, the later patent holder must still obtain a license to make, use, sell or import that portion of the patented invention that is still under valid patents owned by others.
