U.S. Patent and Trademark Office Web Patent Databases. The Patent and Trademark Office (PTO) [72] offers free World Wide Web access, http // www.uspto.gov/main/patents.htm, to a bibliographic patent database that uses the most current patent classification system, this may not match the classification data that appears on the printed patent, and to a full-text patent database that uses the classification data that appear on the printed patent, this may not match the current classification data. The databases start with January 1, 1976, patents. The full text of a patent includes all bibliographical data (e.g., inventor s name, the patent s title, the assignee s name, etc.) and the abstract, full description of the invention, and the claims. All the words in the text of the patent are searchable. If the patent number is known, the patent, regardless of year, can be ordered from the PTO. Automated searching of 1971 to date patents is available at some of the Patent and Trademark Depository Libraries. Prior to 1971 searching can be done at the PTO facilities or at the Patent and Trademark Depository Libraries. Commercial patent search services are also available.

A speciality offered by the World Patents Index is the Company Code. Derwent provides all big patent assignees (circa 21,000 companies) with a four-number code, which remains the same even after a change of name. Derwent calls them Standard Companies. Even smaller companies are awarded a code, but they have to share it with others and is not suitable for searching. A list of codes, following the abbreviations as well as the corporate and institute names, is contained in the manual World Patents Index Patentee Codes. Patentees in pre-1970 documents are searchable exclusively by means of this code.
