What is IDS, and its requirements when applying for a U.S. patent?

An Information Disclosure Statement (IDS) is a formal submission to the U.S. Patent and Trademark Office (USPTO) that lists prior art or other information known to the applicant that may be relevant to patentability. Filing an IDS fulfills the applicant’s duty of candor and good faith to the USPTO under 37 C.F.R. § 1.56.
