VARTA Microbattery GmbH v. Audio Partnership LLC

Roughly two weeks after VARTA Microbattery directly sued Samsung over its provision of Galaxy 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.
