Digital Check Corp.

Digital Check Corp. (commonly "Digital Check") is a privately held US company headquartered at 630 Dundee Rd., Northbrook, Illinois. It traces its origins to 1959, when founder Thomas P. Anderson Sr. started the business as Microseal Corporation; the current corporation was incorporated in Delaware in 1987, and Thomas P. Anderson Jr. serves as Chairman & CEO. It is not publicly traded and has no disclosed outside parent. Size figures from third-party aggregators vary widely and are unverified: employee estimates range from roughly 90–250, and revenue estimates from about $17M to $50M (Owler, SignalHire, Craft.co, Kona Equity). The company reports manufacturing at a California facility.

Products and operations. Digital Check describes itself as a manufacturer of desktop/distributed-capture check scanners for bank teller, branch, remote deposit capture and lockbox applications. Its main scanner lines are TellerScan, CheXpress and SmartSource (the SmartSource brand was acquired from Burroughs, Inc. in 2016). Beyond hardware, it sells image-enhancement and deposit-processing software and peripherals (receipt printers, endorsers, supplies). It is a parent company of subsidiaries in adjacent imaging and payments businesses, including nextScan (microfilm/microfiche conversion scanners, acquired 2015), ST Imaging (digital microfilm readers), Benchmark Technology Group / Benchmark Solutions (acquired January 2021), and Avivatech, a cash-and-check automation software unit formed from Digital Check's and Benchmark's software groups.

Patent-litigation posture. Digital Check appears in the tracked data only as a defendant (0 plaintiff cases, 1 defendant case), consistent with an operating company defending against third-party assertions rather than asserting its own patents. It has no tracked history of filing patent suits.

Notable case. The single tracked matter is Cedar Lane Technologies Inc. v. Digital Check Corp., filed in the District of Delaware (1:22-cv-01629; Judge Richard G. Andrews). Cedar Lane Technologies is widely characterized as a Canadian-based non-practicing entity that acquired patents (reportedly including Intellectual Ventures assets) and has filed hundreds of suits, predominantly in W.D. Tex. and D. Del.; the Korean IP Office's NPE study lists Cedar Lane as an NPE. The asserted imaging-array/JPEG-compression patents (US 6,972,790; US 8,537,242; US 6,473,527) are directed at Digital Check's core check-imaging technology. Per docket reporting, the case ended in a consent judgment with Cedar Lane's claims dismissed with prejudice and Digital Check's counterclaims dismissed without prejudice; no merits ruling issued.
