MPEP Search Help

Enter a Google™-style query and select Google Search. The search is limited to the MPEP pages on the USPTO website.

Select I’m Feeling Lucky to jump directly to the first hit. Use this when searching for a specific MPEP section by number.

Search cautions:

▶ Search includes 35 U.S.C. and 37 C.F.R. as they are printed in the Appendix to the current MPEP, so any search results within the laws or rules may be out of date.

▶ The current MPEP does not incorporate any law, rule, or practice changes announced in Official Gazette notices or the Federal Register after the effective date of the current MPEP.

Full-text Help

Enter a query that conforms to:

Then, select Patent to search the patent database, PGPub to search the Pre-Grant Publication database, or Both to search both databases.

▶  To conduct a search in both databases, the query must conform to both the Patent Advanced Search and the Pre-Grant Publication Manual Search formats. They are similar, but the only search fields that can be used are:

  • TTL/ Title
  • ABST/ Abstract
  • IN/, IC/, IS/, ICN/ Inventor Name, City, State, and Country
  • AN/, AC/, AS/, ACN/ Assignee Name, City, State, and Country
  • ACLM/ Claim(s)
  • GOVT/ Government Interest
  • SPEC/ Description/Specification
  • CCL/ Current US Classification
  • ICL/ International Classification
  • APT/ Application Type
  • APN/ Application Serial Number
  • APD/ Application Date
  • RLAP/ Related US App. Data
  • PRIR/ Foreign Priority
  • PCT/ PCT Information

Number Help

Enter Patent and/or Pre-Grant Publication numbers or search queries separated by spaces.

Examples:

  • Utility patent: 6,912,416 (7 digits)
  • Pre-Grant Publication: 2006/0287614 (4-digit year + ‘/’ + 7 digits)
  • Design patent: D509,901 (‘D’ + 6 digits)
  • Plant patent: PP15,187 (‘PP’ + 5 digits)
  • Reissue patent: RE38,543 (‘RE’ + 5 digits)
  • Defensive Publication: T109,201 (‘T’ + 6 digits)
  • Statutory Invention Registration: H001,523 (‘H’ + 6 digits)
  • Pre-1836 patents: X000,001 (‘X’ + 6 digits)

▶ Commas, slashes, hyphens, leading zeros, the “US” designation, and kind codes may be included or omitted. So the query US6,780,617-B2 is equivalent to the query 6780617.

Link Help

Enter Patent and/or Pre-Grant Publication numbers (no search queries) separated by spaces. Each number is linked directly to the corresponding patent or publication in a new window. This system bypasses the USPTO search system, so it's especially useful when the search system is overloaded.

Assignment Help

Select a query type:

  • Patent or PGPub Number
  • Reel/Frame
  • Assignor or Assignee Name

Then enter a query.

▶ For a “Patent or PGPub Number” query: Enter a seven-digit U.S. Patent Number or an eleven-digit U.S. Pre-Grant Application Publication Number. Examples are given in the Patent/PGPub Number help.

▶ For a “Reel/Frame” query: Enter a six-digit reel number, a ‘/’ symbol, and a four-digit frame number. Leading zeros may be omitted.

▶ For an “Assignor or Assignee Name” query: Enter a name (at least two characters) to search. To search for an individual's name, enter it in the form of Lastname, Firstname.

PAIR Search Help

“Public PAIR” is a service provided by the U.S. Patent and Trademark Office that allows the public to access bibliographic and file-history information for any U.S. patent, U.S. patent application publication (PGPub), or U.S. patent application that is open to the public.

▶ To access Public PAIR, enter Patent numbers, Application serial numbers, and/or Pre-Grant publication numbers separated by spaces. Each PAIR entry will open in a separate window.

Each number in the query should be one of the following:

  • A seven-digit U.S. Patent Number. Examples are given in the Patent/PGPub Number help.
  • An eight-digit U.S. Patent Application Serial Number. The eight-digit number is formed from the two-digit series code followed by the six-digit serial number. Omit all punctuation. For example, to access U.S. Patent Application Serial No. 09/782,732, enter “09782732” and submit.
  • An eleven-digit U.S. Pre-Grant Application Publication Number. The eleven-digit publication number is formed from the four-digit year of publication followed by the seven-digit publication number. Omit all punctuation. For example, to access U.S. Patent Application Publication No. US 2002/0086417 A1, enter “20020086417” and submit.

▶ Commas, slashes, hyphens, leading zeros, the “US” designation, and kind codes may be included or omitted. So the query US6,780,716-B2 is equivalent to the query 6780617.
