We directly represent clients before the UK Intellectual Property Office, the European Patent Office, and the World Intellectual Property Office.

Four specialisms, one multidisciplinary team

Our patent specialists are authorities in four fields: Biotechnology & Pharmaceuticals, Chemistry, Designs & Engineering, and Electronics & Computing. There’s considerable overlap between the groups, so if your case covers several areas, we can assemble a team with expertise in every one.

We also have an SPC & Regulatory Group to offer advice on Supplementary Protection Certificates and related areas of the law.

Protection and strategy

We can advise on topics including:

  • Protecting new inventions and processes
  • Creating and implementing global and national patent-filing strategies
  • Preparing and prosecuting applications to grant
  • Managing patent portfolios and controlling costs to get maximum results from a limited IP budget

Competitor activities

We can help you stay ahead of your competitors, including:

  • Monitoring third-party patent filings
  • Advising on infringement and validity
  • Managing disputes, including European Patent Office oppositions and litigation in general

Oppositions & Appeals

There’s a reason many world-class companies have made us their first choice for patent cases in Europe. Our attorneys are well-known for their copious experience and unparalleled success rates, making them formidable opponents.

European patent opposition cases can stretch across thirty or more territories, requiring up-to-date knowledge of a huge amount of complex and constantly-changing technical and legal issues. This is when you need a team with a proven track record to construct your written case and drive arguments home.

We’ve successfully attacked and defended some of Europe’s most valuable patents across a huge range of technological areas. At any given time, we’re handling more than 250 cases, often co-ordinating our European opposition approach with litigation strategies in other jurisdictions to obtain the most beneficial result for our clients.

Only a very small percentage of patent attorneys have qualified as litigators in the UK – we think it speaks volumes that five of them work for Potter Clarkson. In addition, Potter Clarkson partner, Timothy Powell, has also qualified as a patent attorney advocate of which there are only about six in the UK and the whole of Europe. Of these, Timothy is only one of two who are also trade mark attorney litigators and trade mark attorney advocates.
