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.

All patent documents in a classification are viewed by USPC for relevance to the patent application being searched. Classification searching is best for applications in which a camera location is easily discernable from figures or drawings. Projection televisions and housing areas are also usually described with reference to the figures. Other areas such as remote control, where button configuration or control function as well as tuners for the order of structural components, are best searched this way. Areas where text searching is very useful are the comb-filtering area, since the terms are specific to television, and the chromakeying area, since this art may also fall outside Class 348.
BRS Search/USOCR Database
EAST Coverage: 1920 - 1970, Full Text: 1920 - 1970

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.

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.
