Резюме
The goal of the current study is to analyze the patent protection
status of medical products included in the therapeutic class аngiotensin II receptor
antagonists or sartans. The analysis covered the period 1995-2008. A three – step
internet patent database search methodology was applied in searching EPO, Orange
book and Patent watch. Applications were systematised per IPC code, territory,
manufacturer and date of patent issuing. The patent activity depends on
the time of expiration of the main patent. The highest number of patents granted
for IPC class A61K is due to the fact that this class is related with the therapeutic
possibility of the formulations. Per territory protection activity is similar in regard to
the prefered countries and follows the market dynamics. For some of the products
additional factors might play an important role. Our study shows that a variety of
factors are infl uencing the patent protection policy, such as the time of discovery,
product application, disease priority, technologies etc. It appears that the therapeutic
competition is more important than the generic one related to establishment of
patent profi le of particular INN. This is in contrast with the beliefs that the patent
protection policy affects mainly generic companies.
