According to the complaint, LEDs in backlit mobile phones sold by Conrad are infringing Seoul’s patent for LED light extraction technology. The patent covers fundamental LED chip fabrication technology to extract light efficiently, significantly enhancing brightness. Conrad is currently selling hundreds of different models of Korean, U.S. and China mobile phones.
Seoul has already warned LED backlight unit suppliers of global mobile phones to cease using products suspected of infringement. Seoul investigates mobile phones incorporating such products and will consider whatever legal enforcement is necessary if such infringement continues unabated.
Seoul has established significant LED backlight patents applicable to TVs and mobile phones for enhancing brightness, color qualities, and power consumption reduction of LEDs. In recent litigations, Seoul has asserted 68 of its patents, including five patent litigations involving LED TVs utilizing backlight technology, including against Philips TV products.
“Sensor Electronic Technology, Inc., a subsidiary of Seoul, has also patented fundamental technology for controlling multiple colors to enhance the color quality of mobile phone flash lights,” added Sam Ryu, Seoul’s Vice President of IT business. “We believe that most premium mobile phones are using this technology without authorization. This is a problem that Seoul and its related companies will seek to resolve, because if LED companies do business fairly, it is virtually impossible to produce LEDs that are applied to mobile phones without utilizing these patents.”

4Moving Biotech Enrolls First Patient in Phase 2a Trial of 4P004, a Potential First-in-Class GLP-1 Therapy for Knee Osteoarthritis16.7.2025 08:00:00 EEST | Press release
4Moving Biotech (4MB), a spin-off of 4P-Pharma dedicated to developing first-in-class treatments that modify the natural course of knee osteoarthritis (OA), today announced that the first patient has been enrolled in Phase 2a clinical trial, INFLAM MOTION. The study will evaluate 4P004, an intra-articular GLP-1 analog, as a potential first-in-class therapeutic candidate for knee osteoarthritis. INFLAM MOTION is a multicenter, randomized, double-blind, placebo-controlled Phase 2a trial planned to be conducted across Europe, the United States, and Canada. A total of 129 patients worldwide diagnosed with knee OA will be enrolled to evaluate, for the first time in humans, the efficacy of 4P004. “Enrolling our first patient is a pivotal step toward rewriting the treatment paradigm for knee osteoarthritis,” said Professor Francis Berenbaum, MD, PhD, Chief Medical Officer at 4Moving Biotech. “Almost 600 million people live with OA, yet no disease-modifying therapy has been done to patients.
