Roughly one month after launching its first litigation campaign, Endpoint IP LLC affiliate Aido LLC has initiated a second, this time suing ON Semiconductor (1:19-cv-01110) and STMicroelectronics (1:19-cv-01111) over a patent generally related to pulse width modulated (PWM) amplifiers. The new complaints target provision of certain switch amplifiers, including the NCP2820 Series 2.65 W Filterless Class-D Audio Power Amplifier and TDA7491HV, respectively. Like the video processing patents that Aido asserted against Panasonic last month, the patent asserted here was received as part of a set of December 2018 assignments from Intellectual Ventures LLC (IV) that saw nearly 20 assets transferred to Aido.

Texas monetization firm Endpoint IP LLC has just kicked off two new litigation campaigns. On May 16, the firm’s affiliate Aido LLC sued Panasonic (1:19-cv-00916) over the infringement of two video processing patents that the plaintiff acquired in December from an affiliate of Intellectual Ventures LLC (IV)—two months after Aido’s sister NPE, Aido Mobility LLC, sued Bank of America over another set of former IV patents. Aido’s new litigation was filed the same day as another Endpoint affiliate, Tactus Technologies LLC, launched a campaign of its own, targeting the Pattern Lock feature offered by Android mobile devices from LG Electronics (3:19-cv-01182) and ZTE (3:19-cv-01184).

This year has so far seen monetization firm IPValuation Partners LLC (d/b/a IPVal) open up just one new campaign, via its PC Coma LLC affiliate, which this past week sued Acer, ASUSTek, HP, and Lenovo over a patent broadly concerning temperature control in a portal computer. IPVal has several other active campaigns, however, a number of them asserting patents received from Intellectual Ventures LLC (IV). Meanwhile, Endpoint IP LLC, which was launched last summer by an IPVal cofounder, looks poised to kick off multiple new litigation campaigns—perhaps also involving IV divestitures.

Intellectual Ventures LLC (IV) finished Q4 with at least two more divestitures to NPEs, according to recently released USPTO records. The assignments, which involved two relatively new players in the patent marketplace, included assets originating with Cypress Semiconductor, Duke University, Enhanced Memory Systems, Integrated Device Technology (IDT), or SK Hynix, among others.
