MPEP § 902.03(e)
The automated search tool on examiners’ desktop computers is the Patents End-to-End (PE2E) Search tool (SEARCH). PE2E SEARCH provides examiners with access to the: (A) full text of U.S. published applications since 2001; (B) full text of U.S. patents granted since 1970; and (C) optically scanned full text of U.S. patents granted 1920-1970. Additionally, PE2E SEARCH provides current classification information and images for all U.S. published applications and patents. Images are available for foreign patent documents, and English language abstracts are available for many foreign patent documents published since 1978 using PE2E SEARCH. Specific instructions for gaining access to the various documents can be found on the PE2E SEARCH webpage on the intranet, available on examiners’ desktop computers.
The Patent Public Search tool (PPUBS) is available at www.uspto.gov/PatentPublicSearch.
