In this case, TCL Europe SAS (Claimant) filed a revocation action against Corning Incorporated (Defendant) regarding European Patent EP 3 296 274, titled 'Fining of Boroalumino Silicate Glasses.' The case was heard by the Central Division (Section Munich) of the UPC. TCL argued that the patent lacked novelty, inventive step, and adequate disclosure, among other points. TCL sought to revoke the patent entirely in France and Germany and have Corning pay legal costs. Conversely, Corning sought dismissal of the action and maintenance of the patent.

The court found in favor of Corning, dismissing the revocation action. It determined that the patent was sufficiently disclosed, novel, and inventive. No counterclaim was filed.
