Patent Law Basics

By David R. McKinney and Edwin S. Wall

Every attorney ought to understand some of the basics of patent law. Only registered patent attorneys may file and prosecute patent applications on behalf of clients with the Patent and Trademark Office (PTO). Nevertheless, as a non-patent attorney, basic knowledge of patent law will be helpful to your clients. This article presents some basic principles of U.S. patent law and provides useful guidance for attorneys

What is a Patent?

Patents are intangible personal property that provide a collection of exclusive rights. These include the right to exclude all others, for a specified term of years, from making, using, or selling in the U.S., or importing into the U.S. for sale, the invention claimed in an issued patent.(fn1) Like other types of property, patents can be bought, sold, licensed for others' use, and used as collateral for debts.

The patent system is intended to promote innovation by granting a limited period of exclusive rights in an

invention in exchange for full public disclosure.

Patentable Subject Matter

When seeking a U.S. patent, the first hurdle is to present patentable subject matter. The patent statutes allow patent protection for any "new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof . . . "(fn4) This broad language...
