Texas NPE Dynavair LLC has launched litigation for the first time, asserting a single patent (6,271,645) against a dozen defendants, including AMS, Atmel, Cobham Advanced Electronic Solutions, Eaton, Intersil, Linear Technology, Microchip Technology, NXP Semiconductors (Freescale), OKW Electronics, Samsung, SII Semiconductor, and TI. The ‘645 patent generally relates to balancing energy levels between batteries within a pack. The complaints target the defendants’ cell balancing circuit products, particularly (although not exclusively) for implementation among multiple Li-ion batteries.

Over the past two months, four NPEs with apparent connections to patent monetization firm IP Edge LLC have collectively filed nearly 50 patent infringement suits against operating companies.

Active defendants in these campaigns range from networking companies (Allied Telesis, Sophos) to retailers (1-800-Flowers, Staples), from electronics companies (Hisense, TCL) to wireless carriers (AT&T, T-Mobile).

In the first half of May 2015, RPX saw 15 patent transfers recorded with the USPTO.
