Delphi Corporation (formerly Delphi Automotive Systems Corporation, renamed March 2002) was a Troy, Michigan–based automotive supplier. Incorporated in Delaware in late 1998, it was spun off from General Motors via a February 1999 IPO and full share distribution on May 28, 1999, and traded on the NYSE as DPH. It was the largest U.S. auto parts supplier — roughly 169,000 employees worldwide at the end of 2007 (about 28,000 in the U.S.) and net sales near $29 billion in 2000. It filed Chapter 11 on October 8, 2005, and emerged October 6, 2009 as the privately held Delphi Holdings, owned by creditors led by Elliott Management and Silver Point Capital; the legacy entity was renamed DPH Holdings Corporation. The successor business later became Delphi Automotive PLC (2011 IPO), which split in December 2017 into Aptiv PLC (APTV) and Delphi Technologies (acquired by BorgWarner in 2020).
Products/operations: vehicle electronics, transportation components, integrated systems and modules — electrical/electronic distribution, powertrain and engine management, thermal/HVAC, safety systems (airbags, occupant detection, steering, brakes), interiors and closures, and aftermarket parts — sold to most global OEMs, with GM the largest customer. It divested non-core lines during bankruptcy (steering to GM; interiors/closures to Renco; other assets to third parties).
Litigation posture: operating company defending, not asserting. The database shows one case and zero plaintiff appearances: Automotive Technologies International, Inc. v. Delphi Corporation et al., filed 2008-03-11 in the U.S. District Court for the Eastern District of Michigan, Southern Division (No. 08-cv-11048) — Delphi's home district, not a plaintiff-friendly venue such as E.D. Texas. ATI is a patent asserter tied to inventor David S. Breed, whose portfolio was later assigned to American Vehicular Sciences LLC, an Acacia-backed NPE; Stanford's NPE database labels ATI an "individual-inventor-started" asserter.
Context: the case targeted Delphi's occupant-detection ("PODS") airbag products. In related E.D. Mich. litigation, Judge Robert Cleland invalidated ATI's '253 side-impact sensor patent for lack of enablement (affirmed by the Federal Circuit, September 2007); in the tracked action, the court later granted summary judgment of invalidity/obviousness on several ATI patents (including the '945, '516 and '080 patents).
