Comedian Jang Dong-min said he developed a one-touch label removal technology and registered patented products in nine countries around the world.

MBC 'Save Me!, which aired on the 11th! Holmes' (hereinafter 'Homes') depicts Jang Dong-min, Park Na-rae, and Yang Se-chan leaving for Seocho-dong, Seocho-gu, Seoul, the largest legal concentration area in Korea.

First, the three looked at the luxury villas around Seocho-dong. Looking at Jang Dong-min, Yang Se-chan mentioned the situation of developing a technology that removes label paper with one touch and even registering a patent. With this idea, Jang Dong-min applied for a congratulatory permit in 2021 and completed formal registration the following year.




Chang Dong-min was shy, saying, `Oh, my God. Would you like a drink?," he said, and suddenly took out a drink. Then "I patented it. If you open the lid, the label paper will detach", he said, introducing the one-touch label removal that he patented.

"It's a very good patent, but did you put a drink in someone else's refrigerator to show that?" Kim Sook said, smiling. Yang Se-hyung said "This idea is really good. If the world uses this, doesn't your brother have the patent?" and Jang Dong-min was surprised, saying, "'It has been patented in nine countries around the world.'"

In addition, regarding the process of issuing a patent, Jang Dong-min said, `First, you must apply to the Korean Intellectual Property Office. You also have to pay. You have to pay 46,000 won for application, 143,000 won for examination, and 45,000 won per year for three years after registration. Foreign patents must be paid at least millions of won" he explained.
