I'll research this company before writing the profile.
SmartPhone Technologies LLC is a patent-holding and licensing entity, not an operating company. Its corporate disclosure statements filed in litigation identify Acacia Research Corporation (Nasdaq: ACTG) as its parent and Acacia Patent Acquisition LLC ("APAC") as an affiliate. APAC held an exclusive license (dated July 31, 2009) to smartphone patents owned by Japan's ACCESS Co., Ltd., and on December 14, 2009, APAC assigned its rights in those patents to SmartPhone Technologies. The exact date of the LLC's formation is not verified in public sources; 2009 is the earliest documented activity. Parent Acacia is a New York–headquartered, publicly traded acquirer of IP and businesses (roughly 986 employees company-wide per Yahoo Finance/PitchBook, market cap around $0.4–0.5B as of 2026).
SmartPhone Technologies has no products, revenue operations, or employees disclosed publicly. Its sole function is monetizing an acquired patent portfolio covering smartphone and handheld-computer features — device discovery over Bluetooth, alternate network link fallback, low-bandwidth communications, touchscreen command entry, and PDA calendar management. The patents originated with ACCESS, Palm, PalmSource, Bell Communications Research (Bellcore), and Geoworks. The portfolio was licensed to Microsoft (October 2010, reported as 74 patents) and to Samsung (March 2011).
The case data reflects a classic assertion posture: 11 suits as plaintiff versus 1 as defendant. The single defendant-side appearance is Futurewei Technologies, Inc. et al. v. Acacia Research Corp. et al. (C.D. Cal., Judge Guilford), the declaratory-judgment action Huawei filed the day after SmartPhone sued it; it reached the Federal Circuit as Futurewei Technologies, Inc. v. Acacia Research Corp., 737 F.3d 704 (Fed. Cir. 2013), which affirmed dismissal on first-to-file grounds. Nearly all plaintiff suits were filed in the Eastern District of Texas, Tyler Division, a venue long favored by patent plaintiffs.
Prominent tracked suits include SmartPhone Technologies LLC v. Research In Motion (2010), v. HTC (2010), v. Amazon.com (2011, targeting the Kindle Fire), v. Dell (2012, multiple), v. Huawei (2012), v. ZTE (2012), and v. LG Electronics (2013). Acacia 8-K filings disclose settlements with Huawei and ZTE in mid-2014; the Huawei case, per Jones Day, settled on the eve of trial after claims on five of eight patents were dismissed. Acacia/ACCESS also reportedly asserted the same portfolio against Apple and carriers in Texas filings.
