Announcement on Korean TMS receiving the patent infringement lawsuit of optical glue from Mitsubishi of Japan

Korea TMS Co., Ltd. (hereinafter referred to as "our company") received the reasons for the patent infringement lawsuit from Japan Mitsubishi Chemical Co., Ltd. (hereinafter referred to as "Mitsubishi") on December 8, 2021. For this, our company explained to the customer as follows:
Recently, the disputed products advocated by Mitsubishi: tm-qn-7 Ttc-sol 7175 (Series) and T-5 (only limited to LCD OCA used on some flat panel displays, not related to OLED OCA). The dispute claimed by Mitsubishi is based on Patent No. 1773756 (transparent double-sided tape and application equipment for image display equipment, application date: December 27, 2012); patent No. 1975353 (patent division of 1773756); patent No. 22333056 (patent division of No. 1975353). Mitsubishi claims that the main controversial point is the adhesive sheet of the image display device with the middle layer and the outermost layer. The patent legal department judges that the patent related to the technology has been registered by our company as early as 2008, while Mitsubishi company first registered in 2012, which was later than the patent authorization of our company. On the contrary, Mitsubishi company has a great possibility of patent infringement. For the adhesive sheet The percentage of gel content ranges from 10% to 70% (After Cure). The patent law department determines that the gel fraction is characteristic evaluation value and is not suitable for the patent content of a specific product.
In fact, the disputed products advocated by Mitsubishi have competed with our company in the display industry market for 8 ~ 9 years. Now filing a patent lawsuit is a deception to exert pressure on our customers. The patents owned by our company are applied for and registered 4 years earlier than the patents claimed by Mitsubishi.
Our patent: double sided adhesive tape for multilayer structure optics and its manufacturing method, the application date is December 9, 2008. For the patent infringement lawsuit, it is decided to file an invalid lawsuit with the patent legal department and an infringement lawsuit against our priority patent. The dispute is a part of LCD products and has nothing to do with OLED OCA.
The dispute was a patent infringement lawsuit filed by Mitsubishi Corporation, a large Japanese enterprise, regardless of its brand image, after 8 years of competition with our company in the market. On the contrary, it proved the excellence of our products from the technical level.
At present, for all customer companies whose TMS is in the process of supply, development and operation, our company will carry out as usual. We guarantee that no matter what the outcome of the lawsuit is, the client company will never suffer direct or indirect losses.
Our company makes continuous efforts to make optical adhesive products leading in technology and reaching the best.
As indicated by the year of patent registration, we are proud to say that we have the earliest OCA research and development technology for more than 15 years and commercialize it.
We respect and welcome the continuous efforts of competing companies and bona fide technology competition. However, for any reason, we will investigate and deal with the acts that try to damage our patented technology and company image in accordance with the law. We will take corresponding measures to prove that our results are not fiction and prove their value. Moreover, for the fact that the patent was registered 4 years earlier than the competitor, we will file a lawsuit and claim damages for the three patent infringements of Mitsubishi.
Unfortunately, such incidents have worried all customers, but please wait and see.
In the future, our company will always adhere to the enterprise development policy of "high quality, high efficiency, integrity and pragmatism", and is willing to win the trust and satisfaction of all customers with leading technology, high-quality products and all-round service!
It is hereby announced!
All members of TMS
