The following is a guest post from Schwegman Lundberg & Woessner’s associate Ricardo Moran.
The issues on appeal were whether Travel Caddy, Inc. had committed inequitable conduct for: (i) not disclosing the existence of the litigation on U.S. Patent No. 6,823,992 (“the ‘992 patent”) during the prosecution of the application that matured into U.S. Patent No. 6,991,104 (“the ‘104 patent”; the ‘104 patent is a CON of the ‘992 patent; the ‘104 patent was filed shortly before the ‘992 patent issued); and paying small entity fees, even though Travel Caddy was not entitled to claim small entity status. (PDFs of both patents are available at the end of this post.)
Non-disclosure of the ‘992 patent litigation
To establish unenforceability based on inequitable conduct in the U.S. Patent and Trademark Office (PTO), it must be shown that (i) information material to patentability was withheld from the PTO, or material misinformation was provided to the PTO, with (ii) the intent to deceive or mislead the patent examiner into granting the patent. Therasense, Inc. v. Becton, Dickinson & Co., 649 F.3d 1276, 1290-92 (Fed. Cir. 2011) (en banc). Withholding of material information and intent to deceive or mislead must be established by clear and convincing evidence. Id. at 1287 (citing Star Scientific, Inc. v. R.J. Reynolds Tobacco Co., 537 F.3d 1357, 1365 (Fed. Cir. 2008)).
