- Patent and Trademark Researchers Have Instant Access to the World's Largest In-House Inventory

Thomson Scientific, part of The Thomson Corporation (NYSE: TOC; TSX: TOC) and leading provider of information solutions to the worldwide research and business communities, today announced that research professionals can now order file histories directly through patent and trademark databases on Dialog(R), 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. Thomson Scientific is the world's largest provider of file histories, with an extensive in-house inventory. Its coverage of international file histories spans over 40 languages and countries.

"Providing access to file histories through Dialog enhances the productivity of intellectual property researchers by giving them streamlined access to the resources they need," said David Brown, Executive Vice President, Thomson Scientific, Corporate Markets. "This is another example of how we are leveraging our capabilities to deliver comprehensive patent solutions to our customers."

Thomson File Histories are available from the following Dialog databases: Patents -- CLAIMS(R)/Current Patent Legal Status (File 123) -- CLAIMS(R)/U.S. Patents (File 340) -- Chinese Patent Abstracts in English (File 344) -- Derwent Patents Citation Index (File 342) -- Derwent World Patents Index (for users in Japan) (File 352) -- Derwent World Patents Index First View(SM) (File 331) -- Derwent World Patents Index(R) (File 351) -- Derwent World Patents Index(R) (File 350) -- Eli EnCompassPat(TM) (File 353) -- European Patents Fulltext (File 348) -- French Patents (File 371) -- German Patents Fulltext (File 324) -- IMS Patent Focus (File 447, 947) -- INPADOC/Family and Legal Status (File 345) -- JAPIO - Patent Abstracts of Japan (File 347) -- LitAlert(R) (File 670) -- U.S. Patents Fulltext (1971-1975) (File 652) -- U.S. Patents Fulltext (1976-present) (File 654) -- WIPO/PCT Patents Fulltext (File 349) Trademark -- TRADEMARKSCAN(R) - U.S. Federal (File 226)
