I'll verify the company's profile with web searches.
Let me dig into the more recent Pantech patent-assertion activity and corporate status.
One more check on the entity's current status and the related patent-assertion entity.
Pantech Wireless, Inc.
Company overview. Pantech Wireless, Inc. ("PWI") was the North American subsidiary of Korea's Pantech Group, formed in 2002 and headquartered at 5607 Glenridge Drive, Atlanta, Georgia (with earlier U.S. operations in San Jose, California, and a 2008 move to Atlanta). It is private, wholly owned by Pantech Co., Ltd. (Seoul, founded 1991), historically Korea's third-largest handset maker after Samsung and LG. PWI-specific headcount is not published; the parent reported roughly 2,500–3,500 employees group-wide around 2011. The parent's status changed materially: Pantech entered Korean court receivership in August 2014, was acquired in 2015 by a Solid/Optis consortium, sold to KNA Holdings in 2017, and in 2020 transferred its patents and brand rights to IdeaHub, which established a licensing-focused successor ("Pantech Corporation"). PWI's own current operating status could not be verified.
Products / operations. PWI researched, marketed and developed wireless handsets for North American carriers — AT&T, Verizon, Sprint, Virgin Mobile, Alltel, Helio, Disney Mobile and Rogers. Devices included quick-messaging/feature phones (C300, C3b, Breeze, Laser, Pursuit, Ease), QWERTY messaging handsets (duo, Matrix/Matrix Pro, Slate), Android smartphones (Crossover, Pocket), and the Disney Mobile DM-P100/DM-P205. Wikipedia also lists tablets and USB modems. This was a genuine device-design business, not a licensing shell.
Patent-litigation posture. In the tracked data PWI appears only as a defendant (0 as plaintiff, 2 as defendant) — an operating company defending against patent assertions, not an asserter. Both tracked matters arise from a single NPE campaign.
Notable cases. Triune Star, Inc. v. The Walt Disney Company et al. (C.D. Ill., Peoria, filed Sept. 28, 2007) accused PWI, Pantech Co. and Pantech & Curitel, alongside Disney, WDIG Mobile and LG, of infringing U.S. Patent 6,124,521 ("Telecommunications Locating System," miniature infrared camera). The court granted summary judgment of non-infringement and Rule 11 sanctions in November 2008; the 2009 Federal Circuit entry is the caption order in Triune Star's appeal (No. 2009-1371). Separately, a distinctly named entity, "Pantech Wireless, LLC," has appeared since 2021 as a plaintiff asserting acquired InterDigital-origin LTE/5G patents in the Eastern District of Texas — that is not the entity in the tracked cases.
