We act in all matters relating to patent prosecution, maintenance and enforcement. We prepare, file and prosecute patent applications in the UK and European Patent Offices. We arrange for the filing of non-UK national patent applications through local attorneys in all significant countries in the world and oversee the prosecution of the patent applications to grant. We act in patent infringement negotiations and litigation, whether for patent proprietors or defendants. We also provide patent clearance advice and/or prior art searches. We recognise the importance of the global marketplace and therefore maintain a relationship with local counsel throughout the world. We have particularly close links with local attorneys in all of the major world economies. All of our patent attorneys specialise in one or more of the usual technical fields of chemistry, biotechnology, engineering and physics, and all have particular specialist expertise within those fields.
