TRW Automotive Holdings Corp. (TRW Automotive / TRW) — Full legal name TRW Automotive Holdings Corp.; commonly "TRW Automotive." Founded in 2002 when Northrop Grumman acquired TRW Inc. and sold its automotive division to The Blackstone Group, which took the unit public (NYSE: TRW). Headquarters: Livonia, Michigan. It was a public company until German supplier ZF Friedrichshafen AG agreed in September 2014 to buy it for roughly $13.5 billion including debt; the deal closed in May 2015, the entity was renamed ZF TRW Automotive Holdings Corp., and it was folded into ZF as its Active & Passive Safety Technology division by 2016. Public filings and company releases put it at roughly 66,000 employees in ~26 countries with FY2014 sales near $17.4 billion (FY2012 revenue $16.4 billion).
Products / operations. TRW was an automotive OEM and aftermarket supplier — not an NPE. It was best known as one of the world's largest safety-system suppliers, with product lines spanning occupant safety systems (airbags, inflators, seatbelts, steering wheels), active safety and electronics (radar and camera driver-assist, crash sensors, electronic control units), braking systems, steering, suspension, and aftermarket replacement parts. Reported customers included Volkswagen (its largest), Ford, and General Motors.
Patent-litigation posture. The tracked data show 0 cases as plaintiff and 1 as defendant, consistent with an operating company defending, not asserting. The sole tracked suit is Automotive Technologies International, Inc. v. Siemens VDO Automotive Corp. et al., filed 2006-12-27 in the Eastern District of Michigan (Southern Division, Judge Robert H. Cleland), where TRW Automotive Inc. was named among the parts suppliers, alongside Bosch, Delphi and Siemens. Michigan is not a plaintiff-friendly patent venue; ATI filed parallel automotive-sensor campaigns elsewhere, including Delaware.
Context. Plaintiff ATI (Automotive Technologies International, Inc., of Denville, New Jersey, associated with inventor David S. Breed) is widely characterized as a patent-holding/licensing entity; its patents were later assigned to Acacia Research subsidiary American Vehicular Sciences, per RPX. In a related ATI appeal, the Federal Circuit in 2007 upheld Judge Cleland's ruling that an ATI side-impact sensor patent was invalid and unenforceable. This profile does not address the merits of the tracked case.
