Judgment : Ashim Kumar Banerjee, J. FACTS From the pleadings and rival contentions the admitted position that we arrive at, would be, as stated hereinafter. Kent R-O systems Limited the appellant, would claim to be well known in the field of water purifier. They are engaged in manufacture of water purifier as per the design duly registered and certified by the appropriate authority. The Patent Office of the Government of India would certify the design that we find from the photograph and the equipment produced in Court. The certificate would appear at pages 26-32 of the paper book. The respondents would claim to be also dealing with the business of water purifier. They would buy components as well as case from the market and assemble it in their workshop that they would mark in the name of Aryan Appliances. The subject controversy would relate to the case used by Aryan Appliances that is almost identical with that of Kent R-O systems Limited. The appellant Kent R-O systems Limited would claim, they are registered in class 23-01 whereas Aryan Appliances would also claim, they are permitted user of the case from A.N. Polymer Pvt. Ltd. the registered mark holder under the same class. They would rely upon the patent certificate of A.N. Polymer Pvt. Ltd. appearing at pages 46-52 coupled with a letter of Authority from A.N. Polymer Pvt. Ltd. dated October 06, 2013, copy of which was produced in Court during hearing. We are told, Kent R-O Systems Limited filed the suit against Aryan Appliances, they would claim, they did not know about the A.N. Polymer Pvt. Ltd.. Hence, they could not make them party, however, despite having knowledge Kent R-O Systems Limited up till date did not make any application for amendment bringing A.N. Polymer Pvt. Ltd. into controversy. Kent R-O Systems Limited also did not file any application for cancellation of the registration of A.N. Polymer Pvt. Ltd.. They would insist upon an order of injunction restraining Aryan Appliances in using the design and marketing or selling similar product. Learned Judge did not feel inclined hence, this appeal. [JUDGMENT AND ORDER IMPUGNED Learned Judge passed the order impugned on October 9, 2013 by vacating the earlier interim order passed ex-parte and gave directions for filing of affidavits.

[JUDGMENT AND ORDER IMPUGNED Learned Judge passed the order impugned on October 9, 2013 by vacating the earlier interim order passed ex-parte and gave directions for filing of affidavits. We are told, the application is still pending and awaiting its logical conclusion. RIVAL CONTENTIONS Mr. Rudraman Bhattacharya, learned counsel would base his argument wholly relying on a Full Bench decision of the Delhi High Court in the case of Micolube India Limited Vs. Rakesh Kumar & Ors. reported in 2013 (55) Patent and Trade Mark Cases Page-1 wherein the judgment per majority held, the suit for infringement of a design would also lie against another registered holder. The relevant paragraph is quoted below: “i) A plaintiff could institute a suit for infringement of a design against a defendant, who was also a holder of a registered design. The expression “any person” found in Section 22 of the Designs Act would not exclude a subsequent registrantas, according to us, no such words of limitation are found in said Section. ii) The plaintiff would be entitled to institute an action of passing off in respect of a design used by him as a trade mark provided the action contains the necessary ingredients to maintain such a proceeding. The argument that such a suit could be instituted only after the expiry of the statutory period provided under Section 11 of the Designs Act, does not find favour with us.

(ii) (a) In this context we must note the argument of Ms. Singh, learned amicus, that passing off action may perhaps be maintainable provided the mark has attained secondary meaning. (ii) (a) In this context we must note the argument of Ms. Singh, learned amicus, that passing off action may perhaps be maintainable provided the mark has attained secondary meaning. In our opinion, the issue before us is limited to whether a remedy by way of passing off action would be available qua a registered design used as a trademark by th
