Koreans dominate next generation DMB patent applications
According to an analysis published on October 14th by the Korea Intellectual Property Office of patent applications (492 cases) filed in Korea, the United States, EU and Japan from January, 1993 to October, 2009, Korean companies and Korean institutions have dominated the patent applications related to next generation terrestrial Digital Multimedia Broadcasting. DMB allows watchers to view highdefinition TV broadcasting on a wide screen and to search for information about the scene as it is being broadcast.
Of the 492 patent applications in the four aforementioned countries, 219 cases (44.5%) were filed in Korea. In comparison, 176 cases (35.7%) were filed in Japan, 62 cases (12.6%) in the United States and 35 cases (7.1%) in Europe.
Domestic residents accounted for 93.2% of the cases filed in Korea. Among the related patent applications filed at EPO and USPTO, Korean companies and Korean institutions accounted for 51.4% and 33.9%, respectively, revealing that Korean companies are securing many related foreign patent applications in addition to dominating their own territory.
Korean companies have aggressively entered the field with the goal of taking the lead in the mobile phone market in the era of Smartphone.
“Next generation DMB service has not been commercialized yet so we haven’t reached the patent infringement dispute stage,” said an official at KIPO’s Digital Broadcasting Examination division. “But once this service is available on a wide scale, patent infringement disputes will be common.” He added that applicants should review and carry forward the standards, research, and patent applications simultaneously, and they should try to secure related foreign patent rights.
