The plaintiff sued the defendant for patent infringement regarding its auto-injector patent.
The defendant counterclaimed for a declaration of invalidity.
The Federal Court found that the asserted claims were invalid for overbreadth, as they failed to include essential elements of the invention.
Certain claims were also found to be anticipated by prior art or obvious.
Furthermore, the Court concluded that even if the claims were valid, the defendant's device did not infringe them.
The action was dismissed, and the counterclaim for invalidity was allowed.
