CLAIMS®/Current Patent Legal Status, provided by IFI Patent Intelligence, contains post-issuance legal status information for U.S. patents. The information is obtained from the U,S. Patent & Trademark Office and from the USPTO Official Gazette. Coverage includes: certificates of correction, reassignment, reexamination requests and certificates, extensions, expirations, reinstatements, reissue requests, adverse decisions on interference actions, and disclaimer/ dedication data.
Certficate of Correction: Minor corrections that do not necessitate republication of the patent document are reported in certificate(s) of correction.
Reassignment: Ownership rights to a patent may be transferred from the original or current assignee to another company or individual. Reassignment actions are usually recorded with the U.S. Patent & Trademark Office.
Extensions: In special cases, such as pharmaceutical patents, the normal term for a patent may be extended if the time needed for federal approval of a product has effectively shortened the normal patent protection time period.
Expirations: A patent expires early when the normal maintenance fees are not paid to the U.S. Patent and Trademark Office. (This database does not cover patents that have expired at the end of their normal 17/20-year life.)
Reinstatement: Expired patents may be reinstated if late payment of the maintenance fees is accepted.
Requests for Reexamination and Reexamined Patents: If substantial new questions are raised regarding the patentability of a patent's claims, a request for reexamination can be filed with the U.S. Patent and Trademark Office. The database includes notices of requests for reexamination as well as the reexamination results.
Reissue Requests: Patents may be reissued if the changes are substantial enough to necessitate republication rather than issuance of correction notices. Reissue requests are recorded in File 123, but reissue patent records can be found in File 340.
Adverse Decisions: Interference actions resulting in adverse decisions will adversely affect patent owners' rights to the patent.
Disclaimers and Dedications; Patent owners may disclaim their rights to part or all of their patent, placing it in the public domain.
All records contain the orginal patent assignee, patent number, and publication date. Reassignment data consists of the former assignee (i.e., assignor), new assignee, reassignment action (e.g., full interest, quarter interest, etc.), date of reassignment, reel and frame number of the USPTO microfilm record, and the correspondence address. Other post-issuance status information typically contains the date of the legal action, the date it was recorded in the Official Gazette and any additional applicable information such as request number, descriptive text, etc. Reexamination records also contain the text of any modified claims.
This database includes all U.S. patents for which post-issuance legal status changes described above have been reported.
