Abstract
In a knowledge-based economy, innovation resulting from R & D activities and subsequent management of their legal safety are of particular importance. Incorrect patent law can lead to abuse in the area of innovation security on a large scale through the activities of the NPE organization (patent trolls). This phenomenon is particularly noticeable in the US while in the EU it is at a negligible level.
The aim of the article is to demonstrate and prove by using comparative literature and documents analysis of US and EU, that inappropriate law leads to violations of innovation safety through the unhampered activity of patent trolls, while a change of the law to more restrictive law is a right step to reduce the patent trolling. On the other hand, the author proves that in an area with a less liberal definition of patentability, there are no many violations of innovation safety through patent trolling.
