Seoul Semiconductor Co., Ltd.

In the two cases, which are pending in the U.S. District Court for the Eastern District of Virginia and the German District Court of Düsseldorf, Seoul asserted infringement of its patents by Philips brand TVs, filament LED bulbs, and premium lighting products. Seoul also sought a recall of infringing products as well as the destruction of those products in the German case.
In these lawsuits, Seoul’s patents cover phosphor technology for high-quality color gamut and WICOP technology.
Seoul has developed its phosphor technology together with a Japanese company (“M”) over 15 years and has succeeded in producing LED lights that are the closest spectrum to natural light. Based on the quality of these lights, which is recognized in the industry, Seoul’s phosphor technology can be found in premium lighting products requiring more than CRI (color rendering index) 90, as well as display products.
WICOP is a revolutionary patented technology that is compactly designed without wire bonding or packaging, thus enabling LEDs to be mounted directly in a PCB assembly. WICOP technology has been adopted in over 100 car models, which is approximately 10% of the global automobile market. It is also widely used in about 20% of the global TV market as of 2020.
Seoul has already successfully obtained permanent injunctions against various infringing products several times in Europe and the U.S. In September 2020, the German District Court of Düsseldorf issued permanent injunctions, an order of recall and destruction against filament LED bulbs manufactured by a Phillips brand affiliate. In 2019 and 2021, the U.S. District Court for the Central District of California and the New Jersey District Court issued permanent injunctions against the sales of a Philips TV product and 13 automotive lighting brand LED products respectively.
“While global companies emphasize corporate responsibility, such as ESG, many companies still use copycat products that stole others’ hard-earned technology in order to gain short-term profits,” said Myeong-Ki Hong, CEO of Seoul. “It is a pity that there are unethical companies that seek profits at the expense of others’ sweat and tears,” he added.

TestMu AI Adds Evidence Packs to Kane CLI, Turning Every AI Test Run into One Portable, Shareable File7.10.2026 17:29:00 EEST | Press release
TestMu AI (formerly LambdaTest), the Full Stack Agentic AI Quality Engineering platform, announced evidence packs for Kane CLI, its terminal-first tool for natural language browser and mobile app testing. Every Kane CLI run now produces one sealed .evidence file that holds the complete record of what the AI agent was asked to do, what it did at each step, and what happened. Kane CLI launched in April 2026, giving developers and AI coding agents a way to run tests on real browsers and mobile apps from the terminal, in plain English, with a clear pass-or-fail verdict. Since launch, it has added AI-powered test case generation and the Assurance Lifecycle, which ties tests back to requirement documents. Evidence packs are the next step: a full record of every run. As AI agents write and run more tests, engineering teams need a clear answer to a simple question: what exactly did the agent do, and why did the run pass or fail? That proof is often spread across screenshots, log folders, and d
Medisca and EUROAPI Form Strategic Partnership to Strengthen API Access for Pharmaceutical Compounding7.10.2026 17:07:00 EEST | Press release
Medisca and EUROAPI have formed a strategic partnership focused on expanding API access for pharmaceutical compounding, creating differentiated access in North America and establishing a broader framework for international growth and peptide collaboration.

The partnership with EUROAPI advances that approach. Under the new strategic partnership, Medisca becomes EUROAPI’s first strategic distribution partner focused on bringing its European-manufactured APIs to the North American compounding market. The collaboration includes exclusive supply arrangements for selected APIs and creates a framework to expand the offering ove
iQmetrix Launches Vendor Managed Inventory Integration with Valor Communication7.10.2026 17:00:00 EEST | Press release
iQmetrix, the global provider of Intelligent Commerce Operating Systems for telecom, is launching a Vendor Managed Inventory integration with Valor Communication, a factory-direct wireless accessory manufacturer and distributor serving carriers, retailers, and dealers since 1997.

The integration will be available to retailers across the iQmetrix client base. The addition of Valor Communication marks another step in the rapid expansion of the iQmetrix Partner Ecosystem, bringing clients a growing network of integrated partners that work natively inside the platform they already run their business on.
