patent attorneyA Patent Attorney must register with the United States Patent and Trademark Office. The USPTO registers both attorneys at law as well as persons who are not lawyers. The former are referred to as “copyright, patent, and trademark attorneys” and the latter as “patent agents.”

A patent for an invention is the grant of a property right to the inventor, issued by the United States Patent and Trademark Office. Generally, the term of a new patent is 20 years from the date on which the application for the patent was filed in the United States or, in special cases, from the date an earlier related application was filed, subject to the payment of maintenance fees.

The right conferred by the patent grant is, in the language of the statute and of the grant itself, “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States or “importing” the invention into the United States.

A trademark is a word, name, symbol, or device that is used in trade with goods to indicate the source of the goods and to distinguish them from the goods of others. A servicemark is the same as a trademark except that it identifies and distinguishes the source of a service rather than a product. The terms “trademark” and “mark” are commonly used to refer to both trademarks and servicemarks.

Trademark rights may be used to prevent others from using a confusingly similar mark, but not to prevent others from making the same goods or from selling the same goods or services under a clearly different mark.

A copyright lawyer works to protect “original works of authorship” including literary, dramatic, musical, artistic, and certain other intellectual works, both published and unpublished. A patent attorney is concerned primarily with inventions.
