Detailed Summary
When a groundbreaking pharmaceutical patent is copied by competitors, who has the standing to fight back in court? The patent holder? Or can someone else step into the ring? This case answers a critical question for the IP world: whether an exclusive licensee — a company that holds the rights to use, make, and sell a patented invention without owning the patent itself — has the power to launch a legal battle against infringers. For founders and IP professionals, the answer carries enormous strategic weight.
The plaintiffs in this dispute were the exclusive licensees of the patent holder for Indian Patent No. 232231, a patent covering Canagliflozin, a significant pharmaceutical compound. The defendants, including Clevus, were allegedly manufacturing and offering Canagliflozin tablets in the market under brand names such as Adkana. The plaintiffs claimed this amounted to infringement of the patent they were exclusively licensed to exploit. Faced with what they viewed as unauthorized competition riding on the back of their licensed innovation, the plaintiffs approached the court seeking relief.
The plaintiffs argued that as exclusive licensees, they had the legal standing and the commercial interest to bring a suit against the alleged infringers. They contended that the defendants were manufacturing and selling a product that fell squarely within the scope of Indian Patent No. 232231, thereby violating the exclusive rights granted to them. The defendants, on the other hand, challenged the very foundation of the suit — questioning whether an exclusive licensee, rather than the patent holder, could maintain an infringement action at all. This raised the central legal friction: does the law permit someone other than the patent owner to enforce patent rights?
The court found that a prima facie case existed in favor of the plaintiffs. The decisive legal reasoning rested on Section 109 of the Indian Patents Act, 1970, which empowers an exclusive licensee to file and maintain a suit against patent infringement. By citing this provision, the court confirmed that exclusive licensees are not merely passive beneficiaries of a patent — they are active enforcers of the rights attached to it. The outcome was an interim order in favor of the plaintiffs, pausing the alleged infringing activity while the matter proceeded further.
For founders, startup leaders, and IP professionals, this case delivers a clear and actionable lesson: if your business model relies on holding an exclusive license to a patent, you are not powerless against copycats. Under Section 109 of the Indian Patents Act, 1970, you have the legal standing to file and maintain an infringement suit on your own. This means exclusive licensing arrangements are not just commercial deals — they come with enforceable legal teeth. When structuring IP agreements, ensure your license grants exclusivity, and understand that this exclusivity translates directly into the right to defend the patent in court.
