Patent Litigation

1 specialist practice area in Patent Litigation

The CMS patent litigation team deals with all types of patent disputes including:

  • patent infringement 
  • patent validity 
  • patent ownership
  • SPC entitlement
  • FRAND licence negotiation
  • interpretation of IP licences. 

By virtue of our experience, the patent litigation team is adept at designing multi-jurisdictional enforcement/product market entry strategies for clients. The CMS team well recognises that litigation matters need to be judged as any other asset held by a client company. The commercial rationale underpinning any particular strategy must serve to further the business needs of the company, but also be kept under review. For life sciences companies the team’s ability to coordinate and run patent litigation in parallel with product-related regulatory exclusivity litigation further distinguishes us from our peers and maximises the likelihood of clients obtaining positive results from either procedure.

In addition to patents, our litigation team advises on trade marks and unfair competition, domain names, copyright, design, know-how and other confidential information and database rights.

    "An “extraordinary” team of litigators, which can “step back and point companies and inventors in the right direction rather than getting lost in the detail”. "
