UVM Libraries Research Guides: Patents and Trademarks: Patents

A patent is a legal right to exclude others from the commercial exploitation of a novel, useful, and non-obvious invention.

Patents are granted by a government agency (in the United States, the US Patent and Trademark Office) for a limited term, in exchange for the public disclosure of the invention and its workings.

Patent databases

Most patent information is openly available online. Patent databases and search engines vary by breadth of contents, national or international coverage, basic interfaces and advanced search tools.

USPTO Patent Public Search
Patent Public Search is the USPTO's primary patents database, containing (a) US patent grants from 1790 to the most recent weekly issue date, and (b) published applications since 2001. Searching applications is important because of the "first to file" principle.
Google Patents
Includes patents and applications from USPTO and more than 100 other jurisdictions. See Google Patents vs USPTO below for more details.

Google Patents or USPTO?

Google Patents and the USPTO's Public Patent Search have different advantages. Use both to ensure a comprehensive search strategy.

Google Patents	USPTO
All patent documents, except recent months	All patent documents, updated weekly
USPTO and 100+ other jurisdictions	USPTO patents only
Also contains non-patent literature (technical documents and books indexed in Google Scholar and Google Books)	Only patents
Simple interface designed for quick review of matches	Complex interface designed for precise searching
Searches full documents 1790-present	Searches full documents 1970-present; searches patent numbers, dates, and classifications 1790-present; searches inventor names 1920-present
Searches images with Optical Character Recognition	Searches text 1970-present (more reliable); searches with OCR 1790-1970
Default order of results is relevancy	Default order of results is reverse-chronological
Supports citation analysis across worldwide patents and other prior art	Supports citation analysis across US patents

How to search

1. Search by classification.
The most effective way to search for patents for a specific area of technology is to identify the most relevant classes and subclasses in the Cooperative Patent Classification (CPC) scheme.

a. Search for keywords in patent texts and identify the most common classes/subclasses. Do this by (1) searching Google Patents and reviewing the statistics under "Top 1000 results by filing date" > CPCs; or (2) using Espacenet's CPC-browser.

b. Search for keywords in class/subclass titles and definitions. Do this with the USPTO's Classification Text Search.

c. Search by keyword in a patents database, find relevant patents, then review their classes and subclasses. In Google Patents, look for "Classifications". See "Useful links" for a link to the USPTO's comprehensive list of field codes.

d. Browse the CPC scheme.

2. Search by field.
Patent fields include inventor, assignee (owner), and patent number. Field searching is most useful for finding a known patent.

3. Search by keyword.
An increasing proportion of patents are available online with full text, making keyword more effective. But keyword searches may retrieve an overwhelming number of results or may fail to reflect the technical language used in patent writing. Use keyword searching as a step to identify classes and subclasses; and to supplement classification searching.
