Siebert Financial Corp.

I'll research this company before writing the profile.

Let me verify the plaintiff, Cedar Lane Technologies, and confirm details.

Company overview. Siebert Financial Corp. (NASDAQ: SIEB) is a publicly traded financial-services holding company headquartered at 653 Collins Avenue, Miami Beach, Florida. The enterprise traces its origins to 1934, when Muriel Siebert founded what became Muriel Siebert & Co.; it listed publicly in 1980, and Siebert was the first woman to own a NYSE seat. The Gebbia family controls roughly 42% of common stock. It is a small-cap: about 166 full-time employees, FY2025 revenue of roughly $94.2 million (up ~12% year over year) and net income of about $5.1 million, with market capitalization near $90–100 million as of late 2026 (company 10-K; FT/MarketScreener profiles).

Products / services. Siebert operates two reportable segments. Financial Services — the large majority of revenue — covers retail discount brokerage, investment advisory and wealth management, insurance products, securities lending (stock borrow/loan), market making and principal trading, investment banking and capital markets, and equity compensation-plan administration, run through subsidiaries including Muriel Siebert & Co., Siebert AdvisorNXT, Park Wilshire Companies, RISE Financial Services, Siebert Technologies, and StockCross Digital Solutions. A newer Media, Sports and Entertainment segment (Gebbia Media) covers music production, catalog acquisition, talent management, and sports representation, following the acquisition of Big Machine Rock assets.

Patent-litigation posture. Siebert is an operating company being attacked, not an aggressor. The authoritative case data shows one tracked suit, with Siebert as defendant and zero as plaintiff. The plaintiff, Cedar Lane Technologies Inc., is a Canadian entity that Stanford's NPE litigation database and Unified Patents both classify as a non-practicing patent assertion entity (NPE/PAE) that acquires rather than practices patents.

Notable case. Cedar Lane Technologies Inc. v. Siebert Financial Corp., No. 1:26-cv-00299 (S.D.N.Y., filed Jan. 13, 2026), asserted U.S. Patent 8,577,782 B2, "Trading with conditional offers for semi-anonymous participants" — a financial-trading-method patent aimed squarely at Siebert's brokerage operations. Cedar Lane is a prolific serial filer; IAM and Docket Navigator report it as among the top NPE filers, with hundreds of suits and a settlement rate above 96%, typically concentrated in the Western/Eastern Districts of Texas, though this action was filed in the Southern District of New York. Public litigation records (Patsnap) indicate the case was dismissed with prejudice in April 2026.
