Case Note & Summary
The appellant, CTR Manufacturing Industries Limited, filed a suit for patent infringement against the respondents, Sergi Transformer Explosion Prevention Technologies Limited and others, alleging that the defendants' fire system infringed its patent granted under Section 43(1) of the Patents Act, 1970. The plaintiff sought an interim injunction to restrain the defendants from manufacturing and selling the alleged infringing product. The learned Single Judge dismissed the notice of motion, and the plaintiff appealed. The High Court, after hearing the parties, held that the plaintiff failed to make out a prima facie case for grant of injunction. The court noted that the plaintiff's patent was granted in 2006, while the defendant No.1's patent was granted in 2002, and the products were different. The balance of convenience was in favor of the defendants, as the plaintiff did not demonstrate irreparable injury. The appeals were dismissed, and the interim orders were vacated.
Headnote
A) Patent Law - Interlocutory Injunction - Prima Facie Case - Section 43(1) Patents Act, 1970 - The plaintiff sought injunction alleging infringement of its patent for fire systems. The court held that the plaintiff failed to establish a prima facie case of infringement as the patents of plaintiff and defendant No.1 were different and the plaintiff's patent was not shown to be valid or infringed. The balance of convenience was in favor of the defendant. (Paras 2-5)
B) Patent Law - Balance of Convenience - Interlocutory Injunction - The court found that the balance of convenience did not favor the plaintiff because the defendant had been manufacturing and selling its product since 2002, and the plaintiff's patent was granted later in 2006. Irreparable injury was not established. (Paras 4-6)

Nature of Litigation
Civil suit for patent infringement with application for interim injunction.
Remedy Sought
The plaintiff sought an interim injunction restraining the defendants from manufacturing and selling fire systems allegedly infringing the plaintiff's patent.
Filing Reason
The plaintiff alleged that the defendants' fire system infringed its patent granted under the Patents Act, 1970.
Previous Decisions
The learned Single Judge dismissed the notice of motion for interim injunction on 17th January, 2012 and 15th November, 2011.
Issues
Whether the plaintiff has a prima facie case for grant of interim injunction in a patent infringement suit.
Whether the balance of convenience lies in favor of the plaintiff or the defendant.
Submissions/Arguments
The plaintiff argued that its patent was valid and infringed by the defendants.
The defendants contended that their patent was prior and different, and the plaintiff failed to establish infringement.
Ratio Decidendi
A plaintiff seeking an interim injunction in a patent infringement suit must establish a prima facie case of infringement and that the balance of convenience is in its favor. Mere grant of a patent does not automatically entitle the plaintiff to an injunction; the court must assess the validity and scope of the patent and the likelihood of infringement.
Judgment Excerpts
The plaintiff claims that its patent and defendant No.1’s patent is different.
The plaintiff failed to make out a prima facie case for grant of injunction.
