29.4.2022 03:00:00 EEST | Business Wire | Press release
Seoul Semiconductor Co., Ltd. (“Seoul”), a leading global innovator of LED products and technology, announced that, in April 2022, it has launched patent infringement lawsuits against Ace Hardware, a global retail company, in the U.S., and, in Europe, against a distributor of Conrad Electronic’s sales platform.

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.

Finsei Selects Thredd to Power New Debit Offering20.10.2026 10:00:00 EEST | Press release
Thredd, the AI-first issuer processing platform, today announced a new partnership with Finsei, a London-based payments company, to power the processing infrastructure behind Finsei’s new Mastercard debit offering. The partnership reflects a shared focus on simplifying an increasingly complex payments environment. Businesses operating across markets often rely on multiple providers to manage accounts, payments, foreign exchange, cards and expenses. Finsei is designed to bring those capabilities together, while Thredd provides the underlying payment technology and infrastructure needed to deliver a secure, digital-first debit experience at scale. At launch, physical and virtual cards will be available, followed by both Apple Pay and Google Pay. “Businesses increasingly expect their financial tools to work together rather than operate as a collection of disconnected services,” said Jim McCarthy, CEO of Thredd. “Finsei is building around that expectation, bringing payments, currency manag
BRG Survey Finds 71% of Competition Lawyers Say Global Antitrust Policies Grew More Fragmented over Past Year20.10.2026 10:00:00 EEST | Press release
Global antitrust enforcement is pulling apart along national lines, with 71% of senior competition attorneys reporting that policy became more fragmented across jurisdictions over the past 12 months, according to BRG’s inaugural Global Antitrust & Competition Report. Nearly four in five (78%) also cite cross-border antitrust requirements as a significant or recurring challenge. The report draws on a survey of 155 senior antitrust and competition attorneys across the U.S., Europe and Asia-Pacific (APAC) and in-depth interviews with 18 leading lawyers. It also finds that about 60% of respondents expect antitrust enforcement to expand in scope and intensity over the next 12 months. “Domestic politics and geopolitical considerations increasingly influence the application of competition law across jurisdictions”, said David Parker, a managing director at BRG. “As a result, deal timelines and risk assessments often now have to be built jurisdiction by jurisdiction, from the earliest stage of
Murata Develops World’s Smallest 008004-inch Size (0.25mm × 0.125mm) NTC Thermistor for Space-Constrained Temperature Sensing20.10.2026 05:00:00 EEST | Press release
Murata Manufacturing Co., Ltd. (TOKYO: 6981) (ISIN: JP3914400001) announces the development of the world’s smallest* 008004-inch size (0.25mm × 0.125mm) NTC thermistor, the NCU01 series. Compared with Murata’s previous smallest 01005-inch size (0.4mm × 0.2mm) product, the new series reduces mounting area by approximately 60% while achieving equivalent temperature-sensing performance, with resistance tolerance of ±1% and B-constant tolerance of ±1%. Its ultra-compact size enables temperature sensing to be positioned in increasingly restricted spaces and closer to heat-generating components, supporting more accurate and responsive thermal monitoring in smartphones, wearable devices, and other densely integrated electronic devices.
