S. Michael Bender (“Bender”) appeals from a final decision by the United States District Court for the District of Columbia that granted summary judgment upholding a disciplinary action taken by the director of the United States Patent and Trademark Office (the “PTO” or “agency”) to exclude Bender from practicing before the PTO. Bender v. Dudas, No. 04-CV-1301 (D.D.C. Jan. 13, 2006) (“SJ Order”). Because the PTO’s findings were supported by substantial evidence, and because the disciplinary action was not arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with the law, we affirm.
