Announcement

On February 1, 2022, the United States Patent and Trademark Office (USPTO) released their new search interface, Patent Public Search, which provides full-text searching for all US patents since 1976 as well as by patent number back to 1790, published patent applications since March 1, 2001, and scanned patents (OCR). Patent Public Search will replace the internal tools that are used by USPTO patent examiners.
