Note: The USPTO has no jurisdiction over questions of infringement and the enforcement of patents.

The work of examining applications for patents is divided among a number of examining technology centers (TC), each TC having jurisdiction over certain assigned fields of technology. Each TC is headed by group directors and staffed by examiners and support staff. The examiners review applications for patents and determine whether patents can be granted. An appeal can be taken to the Board of Patent Appeals and Interferences from their decisions refusing to grant a patent, and a review by the Director of the USPTO may be had on other matters by petition. The examiners also identify applications that claim the same invention and may initiate proceedings, known as interferences, to determine who was the first inventor.

In addition to the examining TCs, other offices perform various services, such as receiving and distributing mail, receiving new applications, handling sales of printed copies of patents, making copies of records, inspecting drawings, and recording assignments. At present, the USPTO has over 6,500 employees, of whom about half are examiners and others with technical and legal training. Patent applications are received at the rate of over 350,000 per year. The Office receives over five million pieces of mail each year.

Protecting New Ideas and Encouraging Innovation

The strength and vitality of the U.S. economy depends directly on effective mechanisms that protect new ideas and investments in innovation and creativity. The continued demand for patents and trademarks underscores the ingenuity of American inventors and entrepreneurs. The USPTO is at the cutting edge of the Nation’s technological progress and achievement.
