Cree LED, a brand of Penguin Solutions, filed a patent‑infringement lawsuit on November 12 2025 in the U.S. District Court for the Northern District of Illinois against Promier Products (d/b/a LitezAll) and Tractor Supply Co. The suit alleges that the defendants are infringing six patents covering portable lighting technology, including U.S. Patents 9070850, 9754926, 10439112, 11791442, D790486, and D892066.
The filing is part of Penguin Solutions’ aggressive intellectual‑property enforcement strategy. The company has a 35‑year track record of innovation and has previously sued ADJ Products in December 2024 and NanoLumens in July 2025 for similar patent violations. By targeting the Optimized LED segment—where portable lighting accounts for a growing share of revenue—Penguin Solutions is protecting a key growth area of its business.
By seeking injunctive relief and damages, Penguin Solutions aims to prevent competitors from using its patented designs in portable lighting products, which could otherwise erode its market share and revenue. The lawsuit also serves to deter future infringement and reinforce the company’s valuation of its IP portfolio, potentially influencing investor perception of long‑term growth prospects.
A spokesperson for Cree LED said the company remains confident that the patents are valid and that the defendants have been using the technology without authorization. The company emphasized that the action is a necessary step to safeguard its innovations and maintain its competitive edge in the rapidly evolving LED market.
The portable lighting market is highly fragmented, with numerous small manufacturers competing on price and feature differentiation. By asserting its patents, Penguin Solutions seeks to consolidate its position and limit the ability of lower‑cost competitors to replicate its technology, thereby protecting its premium product lines.
The filing marks a significant legal milestone for Penguin Solutions and could have material effects on its revenue streams and competitive positioning. Investors and industry observers will watch the court’s decision and any subsequent settlement or damages award for signals about the strength of the company’s IP portfolio and its impact on the broader LED lighting sector.
