Search By U.S. Patent or Published Application Number?
TOPIC:In this example you are searching the U.S. patent number 20040001239 in CLAIMS®/U.S.
Patents (File 340). In the CLAIMS database the patents are merged into one record so it is easy to see the published application number and granted patent number. Note: You can also search U.S. Patents Fulltext (File 654) for the fulltext of the published application.
- U.S. patents are assigned numbers based on a continuing series of up to seven digits (e.g. US 5,947,706). To search for a U.S. patent number, enter the two-letter country code, a space, and the patent number with no commas. Prior to November 29, 2000, a U.S. patent application was not published until it was issued as a granted patent.
Example: S PN=US 5947706
- After passage of the American Inventors Protection Act of 1999, the US Patent and Trademark Office was required to begin publishing patent applications filed on or after November 29, 2000. In most cases, publication occurs after the expiration of an 18-month period following the earliest effective filing date or priority date claimed by an application. U.S. published applications are also sometimes referred to as Pre-grant Published Applications or "PGPs" (e.g. US 20040001239). To search for a U.S. published application, enter the two-letter country code, a space and the four-digit year designation followed by the seven-digit publication number retaining all leading zeros.
Example: S PN=US 20040001239
