Aiwa Co Ltd. v. Aivva Enterprises Private Limited & Ors.

In the crowded marketplace of consumer electronics, brand recognition is everything. When a legacy brand like Aiwa has spent decades building trust with consumers, any attempt to ride on its coattails through a confusingly similar name is a high-stakes gamble. This case before the Delhi High Court is a textbook example of how courts protect established brands from copycats, even when the defendant tries to hide behind procedural technicalities. For founders and IP professionals, the lesson is clear: a well-known trademark is a powerful shield, and courts will not let clever spelling tricks defeat it.

Aiwa Co Ltd., the plaintiff, is the owner of the well-known trademark 'AIWA', a name long associated with consumer electronics and audio equipment. The defendants, Aivva Enterprises Private Limited and others, adopted and used the mark 'AIVVA' for their own goods. Aiwa approached the Delhi High Court alleging that the defendants' mark was visually and phonetically deceptively similar to its own, amounting to trademark infringement and passing off. The matter reached the court on 5 January 2023, where Aiwa sought urgent relief to stop the defendants from continuing to use the offending mark.

Aiwa argued that 'AIVVA' was so visually and phonetically similar to 'AIWA' that it was bound to cause confusion among consumers, who would likely believe the defendants' products originated from or were affiliated with Aiwa. Given Aiwa's status as a well-known mark, the plaintiff contended that any such confusion would cause irreparable harm to its reputation and goodwill. On the other side, the defendants attempted to deflect the infringement claim by raising procedural defenses. They argued that Aiwa had prior knowledge of their use of the mark and had failed to disclose certain facts when seeking the injunction. The defendants essentially tried to argue that the plaintiff's hands were not clean and that the court should not grant relief on equitable grounds.

The Delhi High Court was unmoved by the defendants' procedural arguments. The court found that Aiwa had successfully established a prima facie case of both trademark infringement and passing off. The visual and phonetic similarity between 'AIWA' and 'AIVVA' was enough to convince the court that consumer confusion was not just possible but likely. Critically, the court held that the balance of convenience clearly favored Aiwa, and that irreparable harm would result if the defendants were allowed to continue using the confusingly similar mark. The existing ex parte ad interim injunction in favor of Aiwa was confirmed, meaning the defendants had to stop using the 'AIVVA' mark until the final trial resolved the matter.

For founders and IP professionals, this case delivers a sharp reminder: when you are dealing with a well-known trademark, procedural defenses like delayed notice or alleged non-disclosure by the plaintiff rarely save you. Courts prioritize the prevention of consumer confusion and the protection of established brand equity above all else. If you are building a brand, do your homework before choosing a name, especially in crowded markets like electronics. And if you are defending a well-known mark, take heart: a strong prima facie case of infringement and passing off, combined with evidence of irreparable harm, will almost always tip the balance of convenience in your favor.
