Rockwool International A/S v Knauf Insulation Ltd

Rockwool International A/S v Knauf Insulation Ltd

The appeal was dismissed because the Hearing Officer correctly found that the patents as amended were inventive over the prior art, that the amendments did not add matter, and that the plausibility and sufficiency objections were not properly pleaded, particularised, or supported by evidence. The differences between the patents and the prior art were not obvious to the person skilled in the art, and the amendments were not obviously defective.
