Revision of the Duty To Disclose Information in Patent Applications and Reexamination Proceedings

概要

The United States Patent and Trademark Office (Office or PTO) is proposing revisions to the materiality standard for the duty to disclose information in patent applications and reexamination proceedings (duty of disclosure) in light of a 2011 decision by the U.S. Court of Appeals for the Federal Circuit (Federal Circuit). The Office previously issued a notice of proposed rulemaking on July 21, 2011, and due to the passage of time since the comment period closed in 2011, the Office considers it appropriate to seek additional comments from our stakeholders before issuing a final rulemaking. In the current notice of proposed rulemaking, the Office is seeking public comments on the rules of practice, as revised in response to the comments received from our stakeholders.
