Mitsubishi Chemical Corporation (MCC) has filed a lawsuit with the Seoul Central District Court in South Korea against TMS Co. Ltd. related to Optical Clear Adhesive Sheet (OCA). 

 

MCC is seeking an injunction and compensation for damages associated with manufacturing and sales of direct bonding material for smartphones and tablets in South Korea of TMS’s OCA (TM-QN series products, TTC series products, and T5 series products), which MCC ruled as being manufactured and sold by TMS under the MCC patents concerned.

 

The lawsuit seeks an injunction and compensation for damages associated with the manufacture and sale, etc. in South Korea of TMS’s OCA (TM-QN series products, TTC series products, and T5 series products), which MCC ruled as being manufactured and sold by TMS under the MCC patents concerned.

  

The OCA manufactured and sold by MCC has been widely supported and evaluated by panel manufacturers as the industry's first post-UV-cured OCA, obtained by improving customer yield through the realization of excellent difference absorption, cutting processability and foam resistance.

 

The post-UV-cured OCA is a proprietary technology MCC has been developing for many years ahead of other companies. MCC has actively invested in and developed businesses to ensure that customers can use it with peace of mind and has also made proactive efforts to protect and utilize its intellectual property rights.

 

The purpose of this lawsuit is to protect important intellectual property rights that MCC has actively invested in and developed. We believe that this will contribute to the sound development and maintenance of order in the optical materials industry.
