SIMO Holdings Inc. v. Hong Kong uCloudlink Network Technology, Ltd., No. 19-2411 (Fed. Cir. 2021)Annotate this Case
SIMO’s patent deals with roaming charges on cellular networks and describes apparatuses and methods that allow individuals to reduce roaming charges on cellular networks when traveling outside their home territory. SIMO sued uCloudlink)for infringement, alleging that four uCloudlink products came within claim 8 of the patent. The district court granted SIMO summary judgment, concluding that claim 8 does not require a “non-local calls database.” and entered a final judgment of $8,230,654 for SIMO.
The Federal Circuit reversed, rejecting the district court’s claim construction and holding that claim 8 requires two or more nonlocal calls databases. A “plurality of memory, processors, programs, communication circuitry, authentication data stored on a subscribed identify module (SIM) card and/or in memory and non-local calls database” requires “a plurality of” each component in the list, including “non-local calls database.” In responding to uCloudlink’s summary-judgment motion, SIMO did not identify a triable issue on the factual question of whether, as uCloudlink asserted, the accused products lack a nonlocal calls database; uCloudlink is entitled to summary judgment of noninfringement.
