John Mezzalingua Associates, Inc. d/b/a PPC

I'll research this company before writing the profile.

Let me verify the corporate history and the tracked case.

Company overview. John Mezzalingua Associates, Inc., doing business as PPC (also styled PPC, Inc.), was a privately held, family-owned manufacturer of coaxial cable connectivity products headquartered in East Syracuse, New York (DeWitt/Liverpool area). Sources place its founding around 1940–1947; "PPC" originally stood for Production Products Company. In December 2012 the business was renamed PPC Broadband, Inc. and acquired by Belden Inc. (NYSE: BDC) for $515.7 million. Belden's announcement reported PPC 2012 revenues of roughly $238 million; local press reported about 774 employees at the time. Belden remains the parent. Note: a separate company, John Mezzalingua Associates, LLC d/b/a JMA Wireless, was founded in 2012 after the PPC sale and is a different entity from the litigation party here.

Products / operations. PPC designed and manufactured connectors and connectivity hardware for broadband, satellite, and wireless service providers — F-type connectors (including the Snap-N-Seal and EXO lines), drop and hardline connectors, splitters, taps, traps, filters, drop amplifiers, grounding hardware, fiber house boxes, and cable-preparation tools. It held a large patent portfolio (hundreds of patents, per 2012 press) centered on coaxial connector design, including its SignalTight continuity technology.

Patent-litigation posture. Operating company, not an NPE. Its sole tracked case is as plaintiff — John Mezzalingua Associates, Inc. d/b/a PPC v. Thomas & Betts Corporation, filed November 9, 2010 in the Eastern District of Texas — asserting its own coaxial-connector patent. Stanford's NPE Litigation Database classifies the asserter as a "Product company." With one plaintiff-side case and no defendant-side cases tracked, this is a manufacturer enforcing its own portfolio, and the E.D. Tex. filing fits a plaintiff-friendly venue.

Context. The 2010 case was one chapter in a long-running dispute with rival connector maker Thomas & Betts. Earlier iterations included S.D. Florida litigation (01-CV-6752; affirmed by the Federal Circuit in 2003), an ITC Section 337 investigation, and a related 2011 action in the Western District of New York. SEC filings also record 2001–2003 suits against Antec/ARRIS.
