JNTC Concludes Patent Dispute with 'Final Victory' After 3 Years

JNTC, a leading company in 3D cover glass, officially announced on the 26th that it has finally won the Supreme Court case against UTI Co., Ltd. in a patent lawsuit.

A JNTC representative stated, “Taking the patent lawsuit with UTI as an opportunity, we will continue to actively respond legally without any concession against indiscriminate patent lawsuits in the future.”

In February 2021, UTI, a camera window manufacturer, filed a criminal complaint and separately filed a patent infringement lawsuit with the Patent Trial and Appeal Board against JNTC, claiming that “the shape of the side and the side reinforcement analysis results of its camera window product are similar.”

The company said, “From the beginning, although our camera window product’s process and core technology were completely different, the opposing party claimed production suspension, damages, and product disposal against us. The related legal responses took over three years, causing not only financial damage but also forced disclosure of our proprietary process technology, which led to reverse technology leakage damage.”

In fact, JNTC won all three criminal trials (Special Judicial Police, Daejeon District Prosecutors’ Office, Daejeon High Prosecutors’ Office) with a verdict of ‘no charges.’ Furthermore, despite winning all rulings related to the patent infringement lawsuit filed by the opposing company at the Patent Trial and Appeal Board and the Patent Court, the lawsuit was prolonged due to UTI’s appeal to the Supreme Court. The three-year patent lawsuit was finally concluded with JNTC’s final victory at the Supreme Court on the 14th.

Additionally, the company filed a lawsuit to invalidate UTI’s patent registration, citing issues with the core technology related to the patent. JNTC won the first trial at the Patent Trial and Appeal Board, but the second trial at the Patent Court accepted partial amendments to UTI’s patent content and upheld the patent. The Supreme Court also upheld this second trial ruling, meaning “the competitor was ultimately able to maintain only its patent rights after a long litigation period.”

JNTC’s Chief Executive Officer in charge of business, Jang Yongseong, said, “Recently, through differentiated process technologies such as AF (anti-fingerprint) coating technology and AG (anti-glare) etching technology optimized for large-area curved glass, we are accelerating the development of innovative and unique new cover glass products.” He added, “We are seeking even more remarkable growth by reestablishing our position as a global leader in cover glass.”
