Roughly two weeks after VARTA Microbattery directly sued Samsung over its provision ofGalaxy Buds earphones, the subsidiary of Germany’s VARTA AG has hit Amazon (2:10-cv-00052), Audio Partnership (d/b/a Cambridge Audio) (1:20-cv-01568), Best Buy (2:10-cv-00054), Costco (2:10-cv-00051), and PEAG (d/b/a JLab Audio) (2:20-cv-00071), targeting the defendants over the provision or sale of wireless earphones (including those provided by Samsung or JLab Audio) that incorporate microbatteries sourced from either China’s EVE Energy or MIC-Power. In addition to Best Buy, the Audio Partnership and PEAG complaints add a fourth single-cell battery patent to the three asserted in each of the Eastern District of Texas suits filed so far.
VARTA Microbattery, a subsidiary of Germany's VARTA AG, has filed suit against the American division of Korea's Samsung (2:20-cv-00029) over three patents generally related to single cell batteries. The plaintiff targets Samsung’s provision of Galaxy Buds earphones using, for example, ICR 1254 batteries allegedly sourced from EVE Energy, a Chinese company described on its translated website as “focus[ing] on lithium battery innovation and manufacture”. VARTA Microbattery’s infringement allegations focus on those ICR 1254 batteries.
