DYNAMIC OPTICAL INFORMATION STORAGE OR RETRIVEAL

Classification 720/all - subclasses >> 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.

All patent documents in a classification are viewed by USPC for relevance to the patent application being searched. Classification search is most productive where the subject matter relates to visible structural details of an optical disc drive or storage medium details. A text search should be performed to supplement the classification search, where the broad concepts/environment are searched by text rather than by subclasses and then combined with the text search of the inventive concepts. Text searching is most productive where the subject matter relates to non-visual characteristics, such as particular values, materials, and terminology. Inclusive and intelligent use of truncation, synonyms, and proximity is vital. Classification search should be combined with a text search where the relevant subclasses have large numbers of patents and where classification search is most productive. The text search should include only such terms as are necessary to bring the number of patents down to a reasonable number for viewing. Classification search should be combined with text search where the broad concepts/environment are found in particular subclasses and the specific inventive concepts are not easily visually represented. These inventive concepts for example may relate to optical component non-visual characteristics, particular storage medium materials or particular terminology.

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.
