Examiners Must Comply with Confidentiality When Searching Internet
Note:
Examiners must ensure all internet searches comply with confidentiality requirements, especially when visiting social media sites for public information.

The Internet is generally a public forum and most communications made over the Internet are neither confidential nor secure. All use of the Internet by examiners must be conducted in a manner that ensures compliance with confidentiality requirements in the statutes, including 35 U.S.C. § 122, and regulations. As part of an Internet search, examiners may visit social media websites that provide for public interactions, but are not authorized to participate on these websites or otherwise solicit assistance with patent examination even for published applications. For example, an examiner is not authorized to request users of a website to provide additional information not found on the website, elaborate further on information already posted on the website, or post new information on the website. Additionally, any Internet searching that is conducted is to be limited to searching for the information necessary for examination of the application or proceeding, such as the state of the art or the presence or absence of technical features in the prior art.

Patent Examiner Search Strategies Required
Note:
Patent Examiners and STIC staff must formulate individual search strategies when using the Internet to search for patent application information that has not been published.

The responsibility for formulating individual search strategies lies with individual Patent Examiners, Scientific and Technical Information Center (STIC) staff, and anyone charged with protecting proprietary application data. When the Internet is used to search, browse, or retrieve information relating to a patent application which has not been published, other than a reissue application or reexamination proceeding, Patent Organization users MUST restrict search queries to the general state of the art unless the Office has established a secure link over the Internet with a specific vendor to maintain the confidentiality of the unpublished patent application. Non-secure Internet search, browse, or retrieval activities that could disclose proprietary information directed to a specific application which has not been published, other than a reissue application or reexamination proceeding, are NOT permitted.
