Parsons v Convatec Ltd [2024] EWHC 2111 (Pat) (12 August 2024)

In employee compensation claims under s.40(1) of the Patents Act 1977, the invention must be objectively identified by reference to the patent specification, including at least the description and at least one representative claim, but a claim-by-claim approach is not required. Pleadings must clearly link the invention to the relevant patent(s) to enable the parties and the court to understand the case, but need not atomise every claim. Both parties are required to amend their pleadings accordingly to allow the case to proceed efficiently.
