Classification 256/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.

Classification search is narrowed by text. Language can be noisy so a classification search works best for this class. The novelty is often how the rails connect to the post. Drawings are key. Text search alone can be useful when a type of welding or material is claimed. Forward and backward citation searching is useful for this class.
BRS Search/USOCR Database
EAST Coverage: 1920 - 1970, Full Text: 1920 - 1970
WEST Coverage: 1920 - 1970, Full Text: 1920 - 1970
Full text of U.S. patent grants.

PGPUBS
EAST Coverage: 2001 - present, Full Text: 2001 - present

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.

Derwent World Patents Index, Classification and Text Search
EAST Coverage: 1963 - present, Full Text: - N/A
WEST Coverage: 1963 - present, Full Text: - N/A
English abstracts database of patent documents from more than 40 patent-issuing authorities.

Searched using IPC codes.
EPO Abstracts, Text and Classification Search
EAST Coverage: 1978 - present, Full Text: - N/A
WEST Coverage: 1978 - present, Full Text: - N/A
English abstracts database of patents and published applications from EPO, WO/PCT, United Kingdom, France, Germany, and Switzerland. USPC searching is limited to documents added to the database from 1978 to September 30, 1995.

EPO patent documents in a USPC or an IPC classification are viewed for relevance to the patent application being searched. This resource provides relevant foreign art, and is searched using IPC codes.
JPO Abstracts, Text and Classification Search
EAST Coverage: 1976 - present, Full Text: - N/A
WEST Coverage: 1976 - present, Full Text: - N/A
English abstracts database of Japanese published unexamined applications. USPC searching is limited to documents added to the database from 1978 to September 30, 1995.

JPO patent documents in a USPC or an IPC classification are viewed for relevance to the patent application being searched. Searched using IPC codes.

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.
