Plaintiff
4 cases as plaintiff.
Company overview. Rembrandt Wireless Technologies, LP is a privately held patent-holding entity and an affiliate of Rembrandt IP Management, LLC, a Bala Cynwyd, Pennsylvania-based patent monetization fund founded in 2004 by Dr. Paul Schneck. Rembrandt IP Management describes itself as a committed-capital fund that acquires or partners on patents and enforces them against large companies; Forbes reported in 2008 that it had raised roughly $150 million for that purpose. Rembrandt Wireless appears to have no independent staff or revenue of its own, and no reliable public employee or revenue figures exist for the entity. Court filings place it in Bala Cynwyd; a 2011 patent assignment lists an Arlington, Virginia address.
Products / services / operations. It has none. Rembrandt Wireless is a non-practicing entity (NPE/PAE) — a shell licensor created specifically to hold a wireless-communications patent family and litigate it. Its patents, U.S. 8,023,580 and 8,457,228, claim devices that switch between different modulation families (e.g., FSK and QAM/PSK) in a master/slave wireless link; Rembrandt asserted them against Bluetooth Enhanced Data Rate (EDR) implementations. The portfolio traces to inventor Gordon Bremer, with priority to a December 5, 1997 provisional, and passed through Summit Technology Systems, LP to Rembrandt Wireless in 2011. Both patents expired December 4, 2018.
Patent-litigation posture. Purely one-directional: 4 tracked cases as plaintiff, 0 as defendant — the classic NPE signature. Two suits (Samsung, 2013; Apple, 2019) were filed in the Eastern District of Texas, Marshall Division, a historically plaintiff-friendly venue; the 2019 Broadcom and Qualcomm suits were filed in the Central District of California, where those defendants are based, after Apple sought transfer of its Texas case.
Notable cases. A Marshall jury found Samsung infringed and awarded $15.7 million in February 2015; the Federal Circuit upheld liability (853 F.3d 1370) but vacated the damages award on patent-marking grounds. Samsung settled in 2018; Apple's case settled after Apple filed four IPRs, and Qualcomm's IPRs were denied institution. Other Rembrandt IP Management affiliates (Rembrandt Technologies, Rembrandt Social Media, Rembrandt Vision Technologies, Rembrandt Data Storage) have run separate campaigns; RPX reports a roughly $51 million attorney-fee award against Rembrandt affiliates in related litigation.
