Chapter 2000: Duty of Disclosure

This chapter deals with the duties of disclosure. Each inventor and every other individual who is substantially involved in the preparation or prosecution of the application has a duty of disclosure. These duties consist of candor, good faith and the duty to disclose all relevant materials to the PTO.
The test may have a question or two related to the duty of disclosure. Know that once an applicant states that a reference is prior art, it can never be taken back. Another point to remember is that the applicant, registered practitioner and assignees will have a duty to disclose materials relevant to the invented subject matter even after the patent has been allowed and issued.
