Section 21 provides that “any person” may give a Notice of Opposition to the registration of a trade mark whether he has or has not any commercial or personal interest in the matter. The person need not be a prior registered trade mark owner. He can be a customer, a purchaser or member of the public likely to use the goods. The question of bona fides of the opponent does not arise. The opponent is considered to represent not only his own interest but also to some substantial extent, that of the public. Under Section 3(42) of the General Clauses Act, 1897 the word “person” shall include any company or association or body of individuals, whether incorporated or not”. Thus, an un-registered firm or association is a person for the purpose of Section 21 of the Act (See Indian Association of Thermometry Vs. Hicks Thermometers (1981) PTC 121 at 127). However, the expression “any person” does not include a fictitious person or a ghost [(See Rajinder Vs. Devdarshan (1986) PTC 30 at page 35).] In an opposition proceedings, it is more important to consider the matter from the point of view of the public than from the point of view of two parties to the proceedings and, therefore, merits or demerits of the opponent are irrelevant [(See Eno Vs. Dunn & Company (1890) 7 RPC 311)]. The Tribunal will take cognizance of any facts that would render registration improper.
