Sevcon Ltd v Lucas CAV Ltd: HL 1986

A claim was brought for the infringement of a patent. It was brought after the specification had been published, but before the patent had been sealed.
Held: Time might run from a date before the plaintiff was entitled to sue. The cause of action for infringement accrued at the date of the infringement even if that was before the date of sealing but the claim could not be enforced until the procedural requirement of sealing was met.
Lord McKay of Clashfern said: ‘If he were to institute proceedings for infringement before the patent for the invention was sealed, the procedural requirements of the proviso would not be satisfied but a statement of claim could not be struck out as disclosing no cause of action although it might be liable to be struck out as an abuse of the process of the court.’
