Patent Law

At the intersection of law and technology, patent law is an exciting and rapidly growing practice area. A patent is an intellectual property right granted to an inventor “to exclude others from making, using, offering for sale, or selling the invention throughout the United States or importing the invention into the United States” for a limited time in exchange for public disclosure of the invention. The purpose of a patent is to promote innovation through economic incentive, and patent law serves to protect such incentive.


  • The Constitutional authority of patents comes from Article 1, § 8, Clause 8 of the United States Constitution:
    • "The Congress shall have Power To . . . promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries;"
  • Title 35 of United States Code is the primary legislative source of authority. This statute establishes the United States Patent and Trademark Office and sets out the basic stautory authority governing patents.
  • The United States Patent and Trademark Office is the government agency responsible for issuing patents. Its rules are embodied in 37 CFR and the Manual of Patent Examination and Procedure.
  • Federal Courts have developed a large body of judicial authority that governs patents.

United States Patent and Trademark Office

The USPTO is the government agency responsible for patents. Located in Alexandria, VA, the USPTO issues patents and creates rules governing them. USPTO employees responsible for issuing patents are called patent examiners. Patent agents and attorneys work closely with examiners to secure the inventor's intellectual property rights. Albert Einstein was a patent examiner in the Swiss patent office. A patent agent is someone who has passed the Patent Bar and is competent to file patent applications for others. A law school degree is not necessary to become a patent agent. However, many patent agents are also attorneys, and one must be an attorney to litigate a patent case before a court.

International Patents

A United States patent only provides protection for activities within the United States.  Generally, to obtain international protection for an invention, an inventor must seek a patent in the appropriate governing body in each country in which he or she wishes to enforce intellectual property rights. However, a number of international bodies and treaties provide avenues that allow one to obtain protection in multiple countries for a single patent.

Law Firms and Employment

With a great increase in patents filed and litigated each year, patent law is a rapidly growing practice area. Many general practice firms have intellectual property divisions in addition to real estate, tax, or any other practice area. Other law firms specialize in a particular practice area, such as intellectual property and are known as boutiques. As of 2012, the top 10 firms by number of patent agents and attorneys are:

Aside from law firms, patent attorneys and agents also work as corporate counsel, patent examiners, and in many other fields.
