The first U.S. patent was granted in 1790 to Samuel Hopkins of Philadelphia for “making pot and pearl ashes”-a cleaning formula used in soapmaking.
The USPTO furthers effective IP protection for U.S. innovators and entrepreneurs worldwide by working with other agencies to secure strong IP provisions in free trade and other international agreements. It also provides training, education, and capacity building programs designed to foster respect for IP and encourage the development of strong IP enforcement regimes by U.S. trading partners.
The USPTO has evolved into a unique government agency. In 1991 – under the Omnibus Budget Reconciliation Act (OBRA) of 1990 – the USPTO became fully supported by user fees to fund its operations. In 1999, the American Inventors Protection Act established the USPTO as an agency with performance-based attributes; for example, a clear mission statement, measurable services and a performance measurement system, and predictable sources of funding.
The USPTO is more than an approval system – it houses one of the largest repositories of scientific and technical knowledge in the world. It is an organization dedicated to the promotion and progress of science and the useful arts, to bolstering the strength and vitality of the U.S. economy by protecting new ideas and investments in innovation and creativity.
The construction of the campus in Alexandria, Va., was completed in 2005. As one of the largest federal facilities in the country, the USPTO campus consists of five main buildings arranged in a U-shaped pattern with a complementary open-ended U-shaped courtyard in the center. The five main buildings--Remsen, Jefferson, Madison, Knox, and Randolph–are named for men who played important roles in establishing America’s intellectual property protection system. James Madison is generally credited with writing Article 1, Section 8, of the Constitution, which provides the basis for this country’s intellectual property protection system. Thomas Jefferson as Secretary of State, Henry Knox as Secretary of War, and William Randolph as Attorney General comprised the first patent board. They met every Saturday to review applications and issue patents. Henry Remsen was the first clerk of the patent board.
The two million square feet campus houses about 9,000 highly skilled and professional employees and the agency’s museum.
The U.S. Patent and Trademark Office Museum is the agency’s opportunity to showcase how the U.S. patent and trademark systems protect and encourage innovation and the men and women whose creativity has helped foster a strong and prosperous America.

The USPTO Museum features an interactive exhibit area, theatre and store.
The museum currently hosts several interactive exhibits, including the “Art of Invention – Invention of Art,” which features 70 works of art that emerged from inventions, patents and trademarks. The inventors and artists represented in this exhibit produced artistic treasures that also serve a practical purpose.
The museum’s latest addition, a novel high tech “Portrait Gallery” features digital electronic portraits of U.S. Presidents Thomas Jefferson and James Madison; the famous inventor Thomas Edison; National Inventors Hall of Fame Inductees Helen Free, who developed home testing for diabetes, and Steve Wozniak, the inventor and co-founder of Apple Computer; and USPTO Director Jon Dudas.
Through its exhibits, visitors enjoy the ingenuity of mankind and become aware of the vital role that intellectual property plays in every aspect of our lives. The museum and gift shop were developed and are maintained by the National Inventors Hall of Fame Foundation, Inc.
The museum is located in the atrium of the Madison Building, 600 Dulany Street, Alexandria, Va., and is open Monday-Friday, 9:00 a.m. - 5:00 p.m., Saturday, noon - 5:00 p.m., closed on Sundays and federal holidays. Admission is free.
