CHEMISTRY OF INORGANIC COMPOUNDS

Classification 423/326.000 - 334.000 >> 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.

WEST Coverage: 1971 - present, Full Text: 1971 - present

Full text patent and inventor searching.

EAST or WEST is used for full text and class/subclass searching. All patent documents in a classification are viewed for relevance to the patent application being searched. Queries may include classification parameters when combined with other terms to be searched in the technical content of the application.

The Patent Application Locating and Monitoring (PALM) system is a large database system that maintains records for each patent application. PALM is designed to provide on-line access to information on all pending applications, as well as most recently patented and abandoned files. Useful for inventor name searches, for finding related and copending applications, and for looking up continuation data.

USPTO search system for U.S. patents.

PLUS (Patent Linguistics Utility System) is a USPTO search system for US patents that produces a list of the most closely related patents to the application searched. The system provides a list of classes/subclasses where the suggested patents are classified.

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.
