16 . It is not necessary that in order to constitute infringement, the impugned trademark should be an absolute replica of the registered trademark of the plaintiff . When the mark of the defendant is not identical to the mark of the plaintiff, it would be necessary for the plaintiff to establish that the mark being used by the defendant resembles his mark to such an extent that it is likely to deceive or cause confusion and that the user of the impugned trademark is in relation to the goods in respect of which the plaintiff has obtained registration in his favour. It will be sufficient if the plaintiff is able to show that the trademark adopted by the defendant resembles its trademark in a substantial degree, on account of extensive use of the main features found in his trademark. In fact, any intelligent person, seeking to encash upon the goodwill and reputation of a well-established trademark, would make some minor changes here and there so as to claim in the event of a suit or other proceeding, being initiated against him that the trademark being used by him, does not constitute infringement of the trademark, ownership of which vests in some other person. But, such rather minor variations or distinguishing features would not deprive the plaintiff of injunction in case resemblance in the two trademarks is found to be substantial, to the extent that the impugned trademark is found to be similar to the registered trademark of the plaintiff. But, such malpractices are not acceptable and such a use cannot be permitted since this is actuated by a dishonest intention to take pecuniary advantage of the goodwill and brand image which the registered mark enjoys, it is also likely to create at least initial confusion in the mind of a consumer with average intelligence and imperfect recollection. It may also result in giving an unfair advantage to the infringer by creating an initial interest in the customer, who on account of such deceptive use of the registered trademark may end up buying the product of the infringer, though after knowing, either on account of difference in packaging etc. or on account of use of prefixes or suffixes that the product which he is buying is not the product of the plaintiff, but is the product of the defendant.
