USPatents files

Other Individual Country Databases and Auxiliary Files. The USPatents files on ORBIT, supphed by Derwent, are similar ia their contents to the CLAIMS-Bibliographic files, including all the front page information and the full claims language. These files do not iaclude the two-dimensional stmctures provided by IFI, nor do they have IFI s standardization of assignee names. Citation searching is available at a cost considerably less than that for the portion of the CLAIMS-Citation file that covers the same period. 

Besides the worldwide WPI database, Derwent provides on the ORBIT system the USPatents database, a bibhographic file of patent front page and cl aim information for U.S. patents since 1971. Derwent also produces a biotechnology database, GENESEQ, that indexes sequence stmetures of proteins or nucleic acids disclosed specifically or genetically in patents. This database is searchable with special sequence software on the InteUiGenetics system, and is a new addition to STN s database catalog.
