Vifor International Ltd v. MSN Laboratories Pvt Ltd

89506967

Vifor International Ltd challenged an interim injunction order that restricted its patent claims to only the manufacturing process. The Delhi High Court addressed the critical issue of product-by-process claims, emphasizing that the scope of a patent monopoly cannot be limited solely by the process used to obtain the product. The court clarified that claim construction must define the full scope of the invention as disclosed in the complete specification, allowing for broader protection than merely the method.
