Rematec brought an infringement action against Europe Forestry B.V. regarding its wood/biomass shredder patent EP 2 548 648. The Mannheim Local Division found the patent invalid for lack of inventive step over D3 (which prompted the skilled person to address cutting element orientation) combined with D9 (which showed 45-degree oblique ribs in fibrous wood grinding), and revoked it across 13 UPC member states. The infringement action was dismissed as a consequence and Rematec was ordered to bear 75% of costs.
EP 2 548 648 lacks inventive step over D3 combined with D9 for the shredder tooth/cutting element orientation feature (Merkmal 1m)
RespondentLegal basis: Art. 56 EPCNote: The Mannheim Local Division found that D3 taught the skilled person that the choice and arrangement of tearing/cutting elements must be coordinated, prompting the skilled person to consult D9, which showed oblique ribs at approximately 45 degrees to the circumferential direction of the rotor in fibrous wood material grinding, corresponding to feature 1m.
Patent EP 2 548 648 is valid and infringement claims should be upheld
ClaimantLegal basis: Art. 56 EPCReason: The patent was found invalid for lack of inventive step and revoked in its entirety; infringement action was dismissed as a consequence.

- D9 (unspecified publication, fibrous wood material grinding with oblique ribs/strips)Obviousness combination
The court analysed feature 1m of EP 2 548 648 (mill for comminuting material, particularly biomass/wood), which concerns the angular arrangement of tearing and/or cutting elements at the inner wall of the grinding chamber relative to the circumferential direction of the rotor. The court found that D9 discloses oblique strips/ribs at approximately 45 degrees in a fibrous wood material grinder, corresponding to feature 1m.
