INVT SPE LLC v. International Trade Commission, No. 20-1903 (Fed. Cir. 2022)Annotate this Case
INVT alleged that the importation and sale of personal devices, such as smartphones, smartwatches, and tablets, infringed INVT's patents. An ALJ determined that the accused devices did not infringe claims 3 and 4 of the 590 patent and claims 1 and 2 of the 439 patent and that INVT had failed to meet the technical prong of the domestic industry requirement as to those claims.
The International Trade Commission affirmed the finding of no 19 U.S.C. 1337 (section 337) violation. The Federal Circuit affirmed the determination with respect to the 439 patent because INVT failed to show infringement and the existence of a domestic industry. The 439 patent relates to wireless communication systems, specifically an improvement to adaptive modulation and coding, which is a technique used to transmit signals in an orthogonal frequency division multiplexing system. The asserted 439 claims are drawn to “capability” but for infringement purposes, a computer-implemented claim drawn to a functional capability requires some showing that the accused computer-implemented device is programmed or otherwise configured, without modification, to perform the claimed function when in operation. INVT failed to establish that the accused devices, when put into operation, will ever perform the particular functions recited in the asserted claims. The determination with respect to the 590 patent is moot based on the patent’s March 2022 expiration.
