The Delhi High Court has issued an injunction restraining Alchem International Pvt. Ltd. from infringing upon the trademark of Alkem Laboratories Ltd. The court's decision addresses the concept of acquiescence in trademark disputes, emphasizing that mere knowledge of a competing mark does not preclude legal action if the competing mark's use is not substantial enough to cause confusion or harm to the original trademark holder's business interests.
Alkem Laboratories, a company established in 1973, has been using its trademark continuously since its inception. The company became aware of Alchem International in 2005. At that time, Alchem was primarily engaged in the bulk drug and active pharmaceutical ingredient (API) sector and was not directly competing with Alkem in the retail market. It was only in 2018 that Alchem expanded its business activities to include retail products, which posed a potential threat to Alkem's business interests.
Alchem contended that Alkem's delay in initiating legal proceedings amounted to acquiescence, arguing that the suit was barred by limitation due to the long period of inaction. However, the court disagreed with this assertion. Justice Amit Bansal noted that Alkem could not be said to have "slept over its rights" because, until 2018, Alchem's business operations did not pose a significant threat to Alkem's interests. The court observed that Alkem's awareness of Alchem's existence did not necessitate immediate legal action, especially when Alchem's activities were limited and did not directly compete with Alkem's market presence.
The court further clarified that the concept of acquiescence does not apply merely because a trademark holder is aware of another party's use of a similar mark. Acquiescence involves a deliberate decision to tolerate another's use of a mark, leading the other party to believe that the original trademark holder has waived their rights. In this case, the court found no evidence that Alkem had knowingly allowed Alchem to use a similar mark to its detriment.
In granting the injunction, the court emphasized the importance of protecting the interests of trademark holders against infringement that could mislead consumers and harm the original brand's reputation. The decision underscores the judiciary's role in balancing the rights of trademark owners with the need to prevent unjust enrichment by parties who adopt marks that are confusingly similar to established trademarks.
This ruling serves as a significant reminder that trademark holders should actively protect their intellectual property rights and that delays in taking legal action may not always result in the loss of those rights, particularly when the competing mark's use has not been substantial enough to cause confusion or harm. The court's explanation of acquiescence provides clarity on how courts assess claims of passive tolerance in trademark disputes, reinforcing the principle that inaction must be intentional and prejudicial to the rights of the original trademark holder.
