YUMINST wins the patent infringement lawsuit for the original patent for the leak detection sensor!

* YUMINST will respond aggressively for punitive damages compensation.


YUMINST (CEO Kim Dong-hwan) announced on the 24th that YUMINST won a patent infringement lawsuit against Auto Sensor Korea and J-Tech, manufacturers and sellers of counterfeit products that used YUMINST's original patent technology without permission.

In the lawsuit, YUMINST, the patent holder, sued Auto Sensor Korea and J-Tech in the Seoul District Court on May 6, 2015, in a dispute over patent infringement. The companies were found to be guilty of patent infringement in the first trial. Appealing the ruling, the companies went to the second trial court, the Patent Court, on September 20, 2017, but received the same guilty verdict in the infringement decision. They then appealed to the Supreme Court on October 2, 2018, but their appeal was dismissed on January 17, 2019.


A YUMINST company representative in charge of R&D said, "The technology at issue in this patent infringement lawsuit is a technology for an outdoor waterproof leak detection sensor. It does not react to water but selectively reacts only to chemical solutions. It uses a reactive membrane structure that detects leakage and is one of the original technologies developed by YUMINST’s R&D department,” he explained.


Meanwhile, Auto Sensor Korea and J-Tech, which infringed on YUMINST's patented technology, appear to have deposited hundreds of millions of won in damages cited by the court, taking into account the damages suffered by the patent holder by the trial court's ruling, and did not proceed with the hearing ordered by the Supreme Court. As the patent infringement is confirmed by the dismissal decision, YUMINST, the patent holder, must be compensated an amount including interest after the infringement decision.


CEO Kim Dong-hwan of YUMINST said, "Since the company was founded in 2004, we have developed technology related to leak detectors, the first in Korea, and have registered 130 intellectual property rights both domestically and overseas. "This has taken a huge toll on our company," he said.


"With this victory in the patent infringement lawsuit, we will hold strong legal responsibility against companies that infringe patent rights, and in particular, punitive damages will be imposed for infringing." He said, “By utilizing the compensation system to compensate for enormous damages (three times the amount of damages), our country will secure national competitiveness by creating a society where patent rights are recognized and protected.”


Meanwhile, Korea’s leak detection sensor market has been dominated by Japan's Omron, France's TTK, and America's Tyco Termal. Based on printed electronic technology using new sensor materials and conductive ink independently developed by YUMINST in 2007, various new flexible water leakage sensors, liquid sensors and chemical detection sensors were developed. They overcome the shortcomings of existing cable-type sensors and provide a domestic alternative to imported sensors.


In particular, YUMINST's flexible leak detection sensor is a special sensor film that can be custom-made and detected according to each hazardous chemical substance in addition to having superior printed electronic technology and flexible sensors.


It has been introduced in various papers and academic conferences at home and abroad, including the American Institute of Electrical and Electronics Engineers (IEEE) journal, and will not only provide patented new technology but also have high academic and economic value, helping to promote sensor technology in line with government policy and bring technological innovation to the chemical industry.
