The United States Patent and Trademark Office (PTO or USPTO) is an agency in the United States Department of Commerce that issues patents to inventors and businesses for their inventions, and trademark registration for product and intellectual property identification.

The USPTO is based in Alexandria, Virginia, after a 2006 move from the Crystal City area of neighboring Arlington, Virginia. The offices under Patents and the Chief Information Officer that remained just outside the southern end of Crystal City completed moving to Randolph Square, a brand-new building in Shirlington Village, on April 27, 2009.

The head of the USPTO is Teresa Stanek Rea, who began serving as Acting Director[1] following the resignation of Director David J. Kappos, effective February 1, 2013.

The USPTO cooperates with the European Patent Office (EPO) and the Japan Patent Office (JPO) as one of the Trilateral Patent Offices. The USPTO is also a Receiving Office, an International Searching Authority and an International Preliminary Examination Authority for international patent applications filed in accordance with the Patent Cooperation Treaty.


The legal basis for the United States patent system is Article 1, Section 8 of the United States Constitution, wherein the powers of Congress are defined. It states, in part:

"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;"

The mission of the PTO is

  • promoting "industrial and technological progress in the United States and strengthen the national economy" by:
  • administering the laws relating to patents and trademarks;
  • advising the Secretary of Commerce, the President of the United States, and the administration on patent, trademark, and copyright protection; and
  • providing advice on the trade-related aspects of intellectual property.


The USPTO is headquartered at the Alexandria Campus, consisting of 11 buildings in a city-like development surrounded by ground floor retail and high rise residential buildings between the METRO stations of King Street station and Eisenhower Avenue station where the actual Alexandria Campus is located between Duke Street (on the North) to Eisenhower Avenue (on the South), and between John Carlyle Street (on the East) to Elizabeth Lane (on the West) in Alexandria, Virginia.[2] [3] [4] An additional building in Arlington, Virginia, was opened in 2009.

The USPTO was expected by 2014 to open its first ever satellite offices in Detroit, Dallas, Denver, and Silicon Valley to reduce backlog and reflect regional industrial strengths.[5] The first satellite office opened in Detroit on July 13, 2012.[6][7][8][9][10] The 2013 sequestration has put the satellite office for Silicon Valley, which is home to the nation's top patent-producing cities, on hold indefinitely.[11]

As of September 30, 2009, the end of the U.S. government's fiscal year, the PTO had 9,716 employees, nearly all of whom are based at its five-building headquarters complex in Alexandria. Of those, 6,242 were patent examiners (almost all of whom were assigned to examine utility patents; only 99 were assigned to examine design patents) and 388 were trademark examining attorneys; the rest are support staff.[12] While the agency has noticeably grown in recent years, the rate of growth was far slower in fiscal 2009 than in the recent past; this is borne out by data from fiscal 2005 to the present:[12]

At end of FY Employees Patent examiners Trademark examining attorneys
2009 9,716 6,242 388
2008 9,518 6,055 398
2007 8,913 5,477 404
2006 8,189 4,883 413
2005 7,363 4,258 357

Patent examiners make up the bulk of the employees at USPTO. They are generally newly graduated scientists and engineers, recruited from various universities around the nation. They hold degrees in various scientific disciplines, but who do not necessarily hold law degrees. Unlike patent examiners, trademark examiners must be licensed attorneys. All examiners work under a strict, "count"-based production system.[13] For every application, "counts" are earned by composing, filing, and mailing a first Office action on the merits, and upon disposal of an application.

The Commissioner for Patents oversees three main bodies, headed by former Deputy Commissioner for Patent Operations, currently[14] Peggy Focarino, the Deputy Commissioner for Patent Examination Policy, currently Andrew Hirshfeld as Acting Deputy, and finally the Commissioner for Patent Resources and Planning, which is currently vacant.[15] The Patent Operations of the office is divided into nine different technology centers that deal with various arts.[16]

Prior to 2012, decisions of patent examiners may be appealed to the Board of Patent Appeals and Interferences, an administrative law body of the USPTO. Decisions of the BPAI could further be appealed to the United States Court of Appeals for the Federal Circuit, or a civil suit may be brought against the Commissioner of Patents in the United States District Court for the Eastern District of Virginia.[17] The United States Supreme Court may ultimately decide on a patent case. Similarly, decisions of trademark examiners may be appealed to the Trademark Trial and Appeal Board, with subsequent appeals directed to the Federal Circuit, or a civil action may also be brought.

Under the America Invents Act, the BPAI was converted to the Patent and Trademark Appeals Board or "PTAB".[18]

In recent years, the USPTO has seen increasing delays between when a patent application is filed and when it issues. To address its workload challenges, the USPTO has undertaken an aggressive program of hiring and recruitment. The USPTO hired 1,193 new patent examiners in Fiscal Year 2006 (year ending September 30, 2006),[19] 1,215 new examiners in fiscal 2007,[20] and 1,211 in fiscal year 2008.[21] The USPTO expected to continue hiring patent examiners at a rate of approximately 1,200 per year through 2012; however, due to a slowdown in new application filings since the onset of the late-2000s economic crisis,[22] and projections of substantial declines in maintenance fees in coming years,[23] the agency imposed a hiring freeze in early March 2009.[24]

In 2006, USPTO instituted a new training program for patent examiners called the "Patent Training Academy." It is an eight-month program designed to teach new patent examiners the fundamentals of patent law, practice and examination procedure in a college-style environment.[25] Because of the impending USPTO budget crisis previously alluded to, it had been rumored that the Academy would be closed by the end of 2009.[23] Focarino, then Acting Commissioner for Patents, denied in a May 2009 interview that the Academy was being shut down, but stated that it would be cut back because the hiring goal for new examiners in fiscal 2009 was reduced to 600.[26] Ultimately, 588 new patent examiners were hired in fiscal year 2009.[27]

Fee diversion

For many years, Congress has "diverted" about 10% of the fees that the USPTO collected into the general treasury of the United States. In effect, this took money collected from the patent system to use for the general budget. This fee diversion has been generally opposed by patent practitioners (e.g., patent attorneys and patent agents), inventors, the USPTO,[28] as well as former federal judge Paul R. Michel.[29] These stakeholders would rather use the funds to improve the patent office and patent system, such as by implementing the USPTO's 21st Century Strategic Plan.[30] The last six annual budgets of the George W. Bush administration did not propose to divert any USPTO fees, and the first budget of the Barack Obama administration continues this practice; however, stakeholders continue to press for a permanent end to fee diversion.[31]


  • On July 31, 1790, the first U.S. patent was issued to Samuel Hopkins for an improvement "in the making of Pot ash and Pearl ash by a new Apparatus and Process." This patent was signed by then President George Washington.
  • The X-Patents (the first 10,280 issued between 1790 and 1836) were destroyed by a fire; fewer than 3,000 of those have been recovered and re-issued with numbers that include an "X". The X generally appears at the end of the numbers hand-written on full-page patent images; however, in patent collections and for search purposes, the X is considered to be the patent type – analogous to the "D" of design patents – and appears at the beginning of the number. The X distinguishes the patents from those issued after the fire, which began again with patent number 1.
  • Each year, the PTO issues over 150,000 patents to companies and individuals worldwide. As of December 2011, the PTO has granted 8,743,423 patents and has received 16,020,302 applications.[32]


The USPTO examines applications for trademark registration. If approved, the trademarks are registered on either the Principal Register or the Supplemental Register, depending upon whether the mark meets the appropriate distinctiveness criteria. However, this function is declining in popularity as trademark applicants move to cheaper, more straightforward state-by-state registrations.[33][34]


The PTO only allows certain qualified persons to practice before the PTO. Practice includes filing of patent applications on behalf of inventors, prosecuting patent applications on behalf of inventors, and participating in administrative appeals and other proceedings before the PTO examiners and boards. The PTO sets its own standards for who may practice and requires that any person who practices become registered. A patent agent is a person who has passed the USPTO registration examination (the "patent bar") but has not passed any state bar exam to become a licensed attorney; a patent attorney is a person who has passed both a state bar and the patent bar and is in good standing as an attorney.[35] A patent agent can only act in a representative capacity in patent matters presented to the USPTO, and may not represent a patent holder or applicant in a court of law. To be eligible for taking the patent bar exam, a candidate must possess a degree in "engineering or physical science or the equivalent of such a degree".[35]

The United States allows any citizen from any country to sit for the patent bar (if he/she has the requisite technical background).[36] Only Canada has a reciprocity agreement with the United States that confers upon a patent agent similar rights.[37]

An unrepresented inventor may file a patent application and prosecute it on his or her own behalf (pro se). If it appears to a patent examiner that an inventor filing a pro se application is not familiar with the proper procedures of the Patent Office, the examiner may suggest that the filing party obtain representation by a registered patent attorney or patent agent.[38] The patent examiner cannot recommend a specific attorney or agent, but the Patent Office does post a list of those who are registered.[39]

While the inventor of a relatively simple-to-describe invention may well be able to produce an adequate specification and detailed drawings, there remains language complexity in what is claimed, either in the particular claim language of a utility application, or in the manner in which drawings are presented in a design application. There is also skill required when searching for prior art that is used to support the application and to prevent applying for a patent for something that may be unpatentable. A patent examiner will make special efforts to help pro se inventors understand the process but the failure to adequately understand or respond to an Office action from the USPTO can endanger the inventor's rights, and may lead to abandonment of the application.

Electronic filing system

The USPTO accepts patent applications filed in electronic form. Inventors or their patent agents/attorneys can file applications as Adobe PDF documents. Filing fees can be paid by credit card or by a USPTO "deposit account".

Patent search tools

The USPTO web site provides free electronic copies of issued patents and patent applications as multiple-page TIFF (graphic) documents. The site also provides Boolean search and analysis tools.[40]

The USPTO's free distribution service only distributes the patent documents as a set of TIFF files.[41] Numerous free and commercial services provide patent documents in other formats, such as Adobe PDF and CPC.


The USPTO has been criticized for granting patents for impossible or absurd, already known, or arguably obvious inventions.[42]

Slow patent examination and backlog

The USPTO has been criticized for taking an inordinate amount of time in examining patent applications. This is particularly true in the fast growing area[dated info] of business method patents. As of 2005, patent examiners in the business method area were still examining patent applications filed in 2001.

The delay was attributed by spokesmen for the Patent Office to a combination of a sudden increase in business method patent filings after the 1998 Amazon one click patent") in the business method area.

Effective in August 2006, the USPTO introduced an accelerated patent examination procedure in an effort to allow inventors a speedy evaluation of an application with a final disposition within twelve months. The procedure requires additional information to be submitted with the application and also includes an interview with the examiner.[59] The first accelerated patent was granted on March 15, 2007 with a 6-month issuance time.[60]

As of the end of 2008, there were 1,208,076 patent applications pending at the Patent Office. At the end of 1997, the number of pending applications pending was 275,295. Therefore, over those eleven years there was a 439% increase in the number of pending applications.[61]

December 2012 data showed that there was 597,579 unexamined patent application backlog.[62] During the 4 years since 2009, more than 50% reduction was achieved. First action pendency was reported as 19.2 months.
