United States Patent & Trademark Office (USPTO)

The United States Patent & Trademark Office (USPTO) provides resources for the searching of patents and trademarks. It also offers various “how to” links and additional tutorials helpful in locating patents or determining if you have a patentable idea. USPTO website is limited to United States patents only.

Search Engines:

Background Information and Support Tools:

Google Patent Search

Google Patent search includes patents from various countries, including scanned versions of older patents and links to the major patent offices.

Search tip: Google does not share what is or is not included in the search tool, nor the delay in which patents will appear in the tool. Thus, the tool is good for quick searches or exploration. Details searches should be conducted at one of the major country search tools.
