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.

All patent documents in a classification are viewed by USPC for relevance to the patent application being searched. Classification search combined with key/specific terms, such as MPEG2, MPEG4, MPEGI layer3 (mp3), in the technical content of the application. Text searching is mainly used for inventors and relevant dates.

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.

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.
