Company patents
JOLED INC.
JOLED INC.'s patent strategy reveals a surprising and significant decline across nearly its entire portfolio, with core areas like Organic Electronics (OLED) and Display Drivers, representing 33.3% and 31.0% of its patents respectively, experiencing consecutive 50.0% and 100.0% year-over-year declines in 2025. This indicates a dramatic shift away from patenting in its historical display technology strengths, with many categories, including Integrated Circuit Layout & Arrangement and Specialty Semiconductor Devices (Legacy), seeing a complete cessation of patenting activity by 2025.
