legitimate patent dispute could constitute an abuse of dominance. The Opposite Parties have engaged in co-marketing agreements with certain companies for their 'Linagliptin' based drug and thus have not foreclosed the market. With respect to the allegation pertaining to evergreening concerning the Second Patent, it has been submitted that OP-1 filed an international patent application for this patent in 2003 before it was approved in 2010 and the Patents Act, 1970 was amended to curb evergreening. It has been submitted that the Controller of Patents would have considered these amendments when granting the Second Patent. Therefore, the validity of the Second Patent is acknowledged in several countries, including India and Canada. It has been further submitted that an ad interim injunction was granted vide order dated 25.02.2022 against the Informant and made absolute vide order dated 21.04.2022 by the Hon’ble Himachal Pradesh High Court in CS (COMM) No. 3 of 2022 which further strengthens the fact the Second Patent is valid. Neither the Informant nor any third party filed any pre grant or post grant opposition against the Second Patent which establishes the novelty, inventive step, quality and strength of the Second Patent. It has also been submitted that the revocation petition, as discussed above, was filed by the Informant against the Second Patent, in close proximity to undermine the suit for permanent prohibitory injunction filed by the Opposite Parties.
