1 case as defendant.
Dai Nippon Printing Co., Ltd. (DNP) is a Japanese diversified printing and materials manufacturer headquartered at 1-1-1 Ichigaya-Kagacho, Shinjuku-ku, Tokyo. It traces its founding to 1876 and was incorporated in 1894. DNP is publicly listed on the Tokyo Stock Exchange (ticker 7912) and trades over-the-counter in the US as an ADR (DNPLY). For the fiscal year ended March 2025 it reported consolidated revenue of roughly ¥1.46 trillion (about US$9.5–9.6 billion) and approximately 36,900 consolidated employees, per its corporate overview and FT/Forbes company profiles.
Operations. DNP operates three reporting segments: Smart Communication (about 49% of sales), spanning commercial and publication printing, e-books, BPO, identity/security cards, XR and thermal-transfer media; Life & Healthcare (about 34%), covering lithium-ion battery pouches, mobility interior/exterior decorative materials, pharmaceutical manufacturing, medical and food packaging; and Electronics (about 17%), covering semiconductor and display photomasks, OLED metal masks, optical films for displays, and related precision components. The company also operates a beverage business through Hokkaido Coca-Cola Bottling.
Litigation posture. DNP is an operating company with one tracked US patent case, in which it is the defendant (0 as plaintiff). This is a defensive posture against a non-practicing entity, not a two-way litigant. The single suit was filed in the plaintiff-friendly W.D. Tex., before Judge Alan Albright.
Notable case. Cedar Lane Technologies Inc. v. Dai Nippon Printing Co., Ltd., No. 6:21-cv-00597 (W.D. Tex., filed June 11, 2021). Cedar Lane is a Canadian NPE founded in 2019 that acquired patents originating with Intellectual Ventures/AVInnov and has filed hundreds of suits, principally in W.D. Tex. and D. Del., asserting image-processing and communications patents (e.g., US 6,473,527; US 6,972,790). Cedar Lane voluntarily dismissed the DNP action with prejudice on November 29, 2021. No merits findings are reflected in the tracked record.
