The Court of Appeal overturned the Patents Court decision to strike out Glaxo Group’s (GSK’s) claim for an Arrow declaration in proceedings concerning a number of patents relating to dry powder inhaler formulations used in the treatment of respiratory diseases. The Court of Appeal held that GSK’s claim for an Arrow declaration was sufficiently realistic to be allowed to proceed to trial.
