It is becoming increasingly important that the correct representation is selected for defending or pursuing oppositions. At D Young & Co we are well placed to provide you with that representation.


The European Patent Convention (EPC) provides an opposition procedure which allows for the validity of granted European patents to be challenged centrally. For businesses concerned about third party patent rights, the procedure offers a cost effective tool for contesting problematic patents. However, an opposition must be filed at the European Patent Office (EPO) within nine months of the grant of the patent in question and therefore it is important that businesses keep an eye on the patenting activities of at least their main competitors.

D Young & Co patent attorneys are experienced advocates before the EPO Opposition Divisions and Boards of Appeal. We regularly practice across all technological areas both for established clients and on an ad hoc basis for new and returning clients who entrust us with matters of particular importance to them.

We have particular expertise and a good success rate in both defending commercially important patents and clearing the way of third party patents so our clients can continue their commercial activities without fear of infringement.

Trade Marks

Our trade mark advisers are experienced and successful in handling all aspects of trade mark opposition, invalidation and revocation proceedings both before the UK Intellectual Property Office (UKIPO) and the European Union Intellectual Property Office (EUIPO).  We can also co-ordinate actions on a worldwide basis through our network of trusted overseas associates. 

We pride ourselves on our ability to take a proactive, tactical and business-minded approach to such contentious matters to achieve the best possible outcome for our clients, both legally and commercially.
