Christy, Inc. v. United States, No. 19-1738 (Fed. Cir. 2020)Annotate this Case
Christy applied for a patent on its “ambient air backflushed filter vacuum” invention. The patent claiming that invention issued in 2006. Christy paid the patent's $1,000 issuance fee and the $490 3.5-year, $1,800 7.5-year, and $3,700 11.5-year maintenance fees. Christy and its licensee sued competitors for patent infringement. One competitor filed petitions for inter partes review (IPR). The Federal Circuit affirmed the Patent Trial and Appeal Board’s invalidity decision. Aggrieved by the cancellation of 18 claims of the patent, Christy filed a class-action suit, seeking compensation from the government, with a Fifth Amendment takings claim and, alternatively, an illegal exaction claim, seeking compensation amounting to the issuance and maintenance fees, Christy’s investments made in the technologies, and attorney fees spent in defending the IPR.
The Federal Circuit affirmed the dismissal of the suit. The cancellation of patent claims in an IPR does not amount to a compensable taking. Christy’s argument regarding the fees fails because the law requires payment of the fees without regard to any later result of post-issuance proceedings, 35 U.S.C. 41, 151. Christy identifies no statute, regulation, or constitutional provision compelling the fees’ refund if claims are later canceled in post-issuance proceedings. Without showing how the PTO’s actions contravened the Constitution, a statute, or a regulation, Christy cannot state an illegal exaction claim.
