David Parsons v Convatec Limited

David Parsons v Convatec Limited

In employee compensation claims under s.40(1) of the Patents Act 1977, the invention need not be identified by a mechanistic claim-by-claim approach. Instead, the invention must be objectively identified by reference to the patent specification, including at least the description and at least one representative claim, with a clear link to the patent(s) relied on. The pleadings must enable the parties and the Court to understand the invention for which compensation is sought, but need not atomise every claim. Dr Parsons' current pleadings are insufficient and must be amended accordingly.

Procedural Posture

Employee Compensation Under Patents Act (uk) / Pre Case Management Conference (directions on Pleadings)

  1. 1 How should an 'invention' be identified and pleaded in employee compensation claims under s.40(1) of the Patents Act 1977?
  2. 2 Is a claim-by-claim approach required for such identification, or is a broader approach permissible?
  3. 3 Are the current pleadings sufficient to allow the case to proceed?

Ratio Decidendi

In employee compensation claims under s.40(1) of the Patents Act 1977, the invention need not be identified by a mechanistic claim-by-claim approach. Instead, the invention must be objectively identified by reference to the patent specification, including at least the description and at least one representative claim, with a clear link to the patent(s) relied on. The pleadings must enable the parties and the Court to understand the invention for which compensation is sought, but need not atomise every claim. Dr Parsons' current pleadings are insufficient and must be amended accordingly.
