Classification 257/1.000 - 798.000 >> view this class definition

U. S. PATENT RESOURCES

As general guidance, a complete search of U. S. patents in this art area will include the following:

1. A classified search of the original classification class and subclass for the subject matter and the other highly relevant art areas in the US patent documents
2. A text search of the US patent documents; patents, PG PUB, and OCR databases:
• Broad text search for the general inventive concept(s), not limited by classification
• Narrow text search for the specific claimed invention
• Boolean text search employing the relevant inventive terms

The resources listed below are internal USPTO search tools. However, the information that they cover is available either commercially, on the USPTO web site, or in the Public Search Facility on the USPTO Headquarters campus and the Patent and Trademark Depository Libraries.

EAST/WEST

EAST Coverage: 1971 - present, Full Text: 1971 - present

WEST Coverage: 1971 - present, Full Text: 1971 - present

Full text patent and inventor searching.

EAST or WEST can be used for class/subclass, text, inventor, and assignee searching. Queries may include classification parameters combined with other terms. This resource frequently provides highly relevant information from US patents.

WEST Coverage: 2001 - present, Full Text: 2001 - present

U.S. published applications.

This resource can be used for class/subclass, text, inventor, and assignee searching. Queries may include classification parameters combined with other terms. This resource frequently provides highly relevant information from published US applications.

FOREIGN PATENT RESOURCES

Searched separately from the U.S. Patent Search. These databases consist of abstract documents. Text searching abstracts requires the use of different search logic e.g. the use of broad Boolean and/or operators instead of narrow proximity operators.

Derwent World Patents Index and the contents of the EPO Abstracts and JPO Abstracts are available commercially.

This resource provides relevant information on JP published unexamined applications.

NON-PATENT LITERATURE RESOURCES

The resources listed are those that USPTO staff have found consistently yield the most relevant search results. Commercial databases available through a single vendor can generally be searched simultaneously, although it is preferable to search full text and bibliographic databases in separate groupings. In addition to the use of subscription databases and public Internet sites, it is recommended that books, manuals, standards and specifications be considered in the search for prior art.
