Last September, shortly before trial, inventor-controlled Sentient Sensors, LLC and Cypress Semiconductor settled a single-patent case between them. The plaintiff has now picked its litigation campaign back up, suing Xilinx (1:22-cv-00173) over the same patent, also in the District of Delaware, again targeting the provision of certain field-programmable gate array (FGPA) systems-on-chip (SoCs) and related products. District Judge Maryellen Noreika repeatedly noted the effort expended on adjudicating the Cypress dispute, dispensing with Cypress motions for reargument of a post-Markman claim construction issue and for summary judgment of noninfringement, leaving for pretrial proceedings the question of whether to resolve late-breaking disputes over the proper construction of “embedded” within the patent’s claims.
In March 2018, inventor-controlled Sentient Sensors, LLC began litigating a single patent generally related to a controller “that can freely be reprogrammed in the field to work with various inputs and outputs” and that “is similar to a ‘system-on-a-chip’…but…transcends the functional capability of a single integrated circuit”. The plaintiff accused Microchip (Microsemi) of infringement in an Eastern District of Texas case that ended roughly one year later, in April 2019. Now, Sentient Sensors has tagged Cypress Semiconductor (1:19-cv-01868) in the District of Delaware, accusing the defendant of infringing the same patent through the provision of its “Programmable System on a Chip (“PSoC®”) lines of system-on-a-chip (SoC) products including the PSoC 3, PSoC 4, PSoC 5, and PSoC 6 product lines”.
Sentient Sensors, LLC, an inventor-controlled New Mexico plaintiff, has filed its first lawsuit, accusing Microsemi (2:18-cv-00121) of infringement through the provision of its SmartFusion and SmartFusion2 system-on-a-chip (SoC) product lines. The complaint asserts a single patent described in court documents as generally related to a controller “that can freely be reprogrammed in the field to work with various inputs and outputs” and that “is similar to a ‘system-on-a-chip’…but…transcends the functional capability of a single integrated circuit”. This campaign is the second over the same patent, after Blemel Technologies LLC, a New York entity affiliated with General Patent Corporation (GPC), asserted it against National Instruments in a 2015 suit.
