The adoption of the regulations for the unitary patent and unified patent court has been hailed as an historic achievement and the target implementation date for the unitary patent and unified patent court was originally scheduled for April 2014, though late 2015/2016 now looks more likely. Unitary patents will be treated as a single patent in potentially 24 or 25 (out of 28) EU member states and will not require separate validation and translation in each of those member states. The aim of the unitary patent system is to make Europe more attractive for investors and to bring Europe more into line with patent systems in Asia and the US.
This page comprises a collection of our posts on the subject of the unitary patent package (unitary patent and unified patent court). The posts in the “All Posts” section are provided in date order (most recent first). A selection of these posts are also grouped into a “Reference Posts” section and these represent our overview of the proposed system as we understand it so far.
