OPTICAL: SYSTEMS AND ELEMENTS
U. S. PATENT RESOURCES
As general guidance, a complete search of U. S. patents in this art area will include the following:
- 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
- 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.
This resource can be used for class/subclass, text, inventor, and assignee searching. Queries may include classification parameters combined with other terms. Depending on the specific subjects covered in the patent application, the search may include related US subclasses within and outside of Class 359. See the Class Definition. This resource frequently provides highly relevant information from US patents.
BRS Search/USOCR Database

- WEST Coverage: 1920 - 1970, Full Text: 1920 - 1970
Full text of U.S. patent grants.
This resource can be used for class/subclass, text, inventor, and assignee searching. Queries may include classification parameters combined with other terms. Depending on the specific subjects covered in the patent application, the search may include related US subclasses within and outside of Class 359. See the Class Definition. This resource provides relevant information from older US patents when it is appropriate to search pre-1971 art using search terms in addition to classification.
PGPUBS
- EAST Coverage: 2001 - present, Full Text: 2001 - present
- 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. Depending on the specific subjects covered in the patent application, the search may include related US subclasses within and outside of Class 359. See the Class Definition. 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.

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.
