U.S. Patents. This file, produced by Derwent, Inc., covers U.S. patents from 1971 to the present. The database iacludes all bibliographic and front page information and the text of all claims. (Prom 1971 to 1974 the claims from many patents were not available from the United States Patent and Trademark Office (USPTO) source tapes, and therefore are not iacluded.) The complete cl aim text can be searched from 1971 but can be ptinted only from 1982. Tides and patentee names are present ia their original form, aeither expanded nor standardized. There is no enhanced iadexiag. Examiner citations are directly searchable, and USPTO classification is updated when the tapes are received from the Patent Office. [Pg.125]

Country codes in brackets are obsolete ICIREPAT codes. Country codes in parentheses were used by Derwent PubHcations Ltd. prior to the adoption of International Standards Organization (ISO) country codes. The obsolete codes remain on printed records, but have been replaced by current codes in on-line DATABASES. Eor Japanese patents, Derwent replaced the second character of the country code with the first digit of the pubHcation year prior to 1992 this variant of the company code is stiU found in on-line databases and printed pubHcations. [Pg.51]

Derwent Information Ltd. Derwent Information Ltd., previously known as Derwent PubHcations Ltd., changed its name in the 1990s to reflect more accurately the fact that its products go far beyond traditional pubHcations.
