Increase in Patent applications on stent for expanding blood vessel


 


As the number of death from disease on the brain and heart blood vessel increases topping the list of deaths from workrelated diseases in 2008, much attention has been drawn to the technology of curing the disease, which is reflected in the trend of patent applications on the stent which is a device for treating the brain and heart blood vessel disease by expanding blood vessel.


 


According to the KIPO (commissioner Suwon Lee), total 268 patent applications on stent has been filed from 2000 to 2009, increasing from 16 filings in 2000 to over 40 filings every year since 2007.  Since 2005, especially, the filings by domestic applicants have been increasing making up 90% of the applications last year.


 


Among the domestic filings, companies filed 95 cases(77.2%) followed by universities with 14 filings(11.4%), individuals with 10 filings (8.1%) and governmentinvested research institutes with 4 filings (3.3%).


 


Especially notable is the sharp increase with 10 filings last year by the industry and university collaboration group which started from 2006.  This seems to be the results of government investment on the related technologies in response to the surge in the death from disease on the brain and heart blood vessel.


 


On December, 2008, the government decided to invest 22.5 billion won in the research of the brain and heart blood vessel disease, and the fusion research institute of brain and heart blood vessel disease of Yonsei University is developing ‘next generation stent’ supported by the government.


 


Following the trend, the KIPO has sent a patent strategy expert of R&D patent center to the fusion research institute of brain and heart blood vessel disease of Yonsei University, thereby supporting building patent portfolios through IPcentered R&D cooperation strategies.  Through the KIPO’s business, it is expected that strong patent portfolios including core and source patents are expected to be built on the area of brain and heart blood vessel disease.
