Information solutions provider Thomson Scientific, part of Thomson Corporation, US, has announced that research professionals can now order file histories directly through patent and trademark databases on Dialog, giving researchers the complete information on a patent or trademark in one place.
File histories are up-to-date accounts of the prosecution history for published or granted patent cases and trademarks. Also called 'file wrappers,' file histories provide the full history of a patent including all documentation of the correspondence between the examiner at the patent office and the applicant or their representatives.
Each electronic patent file history automatically includes a family report with a complete INPADOC family list for the source document. For each family member, patent researchers will see U.S. litigation information; U.S. post-issuance assignment data; U.S. post-issuance data, including assignment data; maintenance fee status; and legal status. International file histories span over 40 countries, providing a comprehensive look at the whole history of an invention.
