Court of Appeal decision (English) on the appeal in the counterclaim for revocation and the related infringement action concerning Seoul Viosys's EP (LED patent, EP 698). The CoA found added matter in claim 1 of the patent (content extended beyond the earlier application as filed, particularly regarding embodiments with a single mesa). Claims 1, 4, 5, 6 and 9 revoked. Infringement action dismissed. Viosys ordered to pay expert's costs for both appeal and first instance proceedings. Key headnotes: court may raise added matter of its own motion; translation of international application governs content; patentee must demonstrate inaccuracy of its own translation.
