Pfizer Inc. v.Incepta Pharmaceuticals Limited
The court confirmed an ex-parte ad-interim injunction granted earlier, restricting defendants from dealing in infringing products related to Patents No. 243571 and 250050, as other patents had expired. The court also directed service of notice for discovery regarding the origin and import of impugned products and allowed amendments to the plaint.
E.R.Squibb & Sons Llc and Ono Pharmaceutical Co. Ltd. v.Union of India, The Controller of Patents & Designs, Zydus Healthcare Limited
The petitioners, international pharmaceutical companies, challenged the recommendations of the Opposition Board regarding their granted patent (IN340060). They argued that the board improperly considered a rejoinder filed by the opponent and failed to consider additional evidence submitted by the petitioners. The court found that the Controller's failure to pass orders on procedural applications led to an incomplete scrutiny, thus vitiating the recommendations.
Pawan Kumar Goel v.Dr. Dhan Singh & Anr.
The plaintiff filed a suit claiming infringement of Patent 369150, which covers a novel process for extracting Alpha Yohimbine. The plaintiff sought an interim injunction to stop the defendants from using or manufacturing the subject compound.

Bayer Pharm Aktiengesellschaft v.The Controller General Of Patents And Designs
Bayer appealed the refusal of its patent application (No. 5818/DELNP/2006), which was rejected on grounds that the composition did not meet criteria under Sections 3(e) and 3(i) of the Patents Act, 1970. The High Court found that the Controller failed to adhere to principles of natural justice by not clearly communicating all objections in the hearing notice, and ruled that the claimed composition was patentable.
Novartis Ag & Anr. v.Medisave Formulations India Llp
The Delhi High Court granted interim relief in the trademark infringement suit filed by Novartis against Medisave Formulations. Recognizing the urgent nature of the case, the court exempted the plaintiffs from standard procedural requirements like advance service and pre-institution mediation. Crucially, the court appointed a Local Commissioner to conduct a search at the defendant's premises, seize infringing products bearing the mark 'ZYMADA', and inspect relevant financial documents, finding prima facie evidence of deceptive similarity between the marks and packaging.
Eli Lilly And Company Private Limited v.Eskayef Pharmaceuticals Limited
Plaintiffs, Eli Lilly And Company, filed a suit alleging infringement of their Indian Patent No. IN 297760 (covering Abemaciclib) by the Impugned Drug 'Abeclib', manufactured by Defendant No. 1. The court prima facie found that 'Abeclib' infringes the patent and granted an interim injunction.
Wyeth Llc v.The Controllers Of Patents
Wyeth LLC appealed an impugned order regarding its patent application. The core dispute revolves around amendments made by the appellant from a PCT application (claiming a 'regimen') to subsequent national phase applications (claiming a 'combination' and 'pharmaceutical pack'). Wyeth argues these amendments were within the scope of Section 59 of the Patents Act, 1970.
Pfizer Inc. v.Beacon Pharmaceuticals Limited

Bdr Pharmaceuticals International Pvt Ltd v.Kudos Pharmaceuticals Limited & Anr
This order addresses an interim injunction application filed by Kudos Pharmaceuticals Limited (Plaintiff) against Bdr Pharmaceuticals International Pvt Ltd (Defendant). The court noted that the suit patent IN'720 was nearing its expiration date. The parties debated whether to proceed with the hearing given the imminent expiry and broader legal questions regarding patent coverage versus disclosure.
Kudos Pharmaceuticals Limited v.Natco Pharma Limited
This order addresses an application seeking five corrections to a previous judgment dated March 1, 2024. The plaintiffs sought corrections primarily regarding the timeline of Natco's revocation filing relative to Kudos' infringement suit, and technical errors in referencing patent numbers and claim descriptions.
Merck Sharp & Dohme Corp. v.Ranvir Kumar Bindeshwari Singh
The plaintiffs filed a suit for patent infringement regarding Sitagliptin (Patent No. 209816). An ex-parte ad interim injunction was previously granted restraining the defendants from dealing in infringing products. The court noted that the patent has since lapsed, making the injunction infructuous, but allowed the plaintiffs to seek relief of costs and damages.
Micro Labs Limited v.The Controller Of Patents
Micro Labs Limited filed this Commercial Suit seeking the revocation of Indian Patent No. 243301 and an injunction against Boehringer Ingelheim Pharma GMBH Co. KG. The court noted that the same parties were involved in related proceedings before the Delhi High Court. Consequently, the application to withdraw the suit was allowed.
Rexcin Pharmaceuticals Private Limited v.The Registrar of Trade Marks
The Madras High Court intervened in a protracted dispute involving the renewal of the trademark 'GENTALENE.' The petitioner sought relief against the Registrar, who had refused renewal citing statutory limitation. The court found that the Trade Marks Registry's own extreme delay—taking over 32 years to issue the registration certificate despite multiple assignments and opposition dismissals—rendered its insistence on strict adherence to limitation rules unjust. Consequently, the High Court directed the Registry to accept the renewal application, effectively overriding the procedural lapse caused by administrative inaction.
Erytech Pharma v.The Assistant Controller of Patents and Designs
Erytech Pharma filed a Transfer Civil Miscellaneous Appeal (Patents) challenging the Assistant Controller's decision regarding Indian Patent Application No. 661/CHENP/2010. The appellant subsequently sought and was granted leave to withdraw the appeal.

The Delhi High Court registered the commercial suit filed by Glaxo Group Limited against Mohd. Nazim And Anr., concerning alleged trademark infringement of 'AUGMENTIN' by the use of 'ZENMENTIN' for similar pharmaceutical products. The court allowed several procedural applications, including exemption from pre-institution mediation and granting permission to submit sealed documents related to sales figures. Crucially, the court directed that notice be issued to the defendants regarding the injunction application (I.A. 5188/2024), setting the stage for a full trial on the infringement claim.
Vertex Pharmaceuticals Incorporated v.Controller General Of Patents, Design, Trademark And Geographical Indications & Ors.
The petitioner challenged the acceptance of a pre-grant opposition by the Patent Office despite an internal decision to proceed with the patent grant. The court addressed procedural issues related to the timing of the decision versus the filing of the opposition, referencing Section 43 of the Patents Act.

Kudos Pharmaceuticals, the registered proprietor of Patent IN 228720 for 'Phthalazinone derivative' (Olaparib), filed a suit against Natco Pharma Limited alleging infringement due to Natco manufacturing and selling its generic version under the brand name BRACANAT.

Duke University v.Deputy Controller of Patents & Design
Duke University appealed the rejection of its patent application for 'LASOFOXIFENE TREATMENT OF ER+ BREAST CANCER' by the Deputy Controller.

Alkem Laboratories Limited v.Orchid Healthcare (A Division Of)
The Madras High Court allowed Alkem Laboratories Limited's appeal against the Trade Mark Registry's decision to register 'TAXTAM'. The court found that despite the registry listing several differences (such as product type or price), the marks 'TAXIM' and 'TAXTAM' were phonetically and visually deceptively similar. Citing established legal precedent, the High Court set aside the impugned order and directed the rectification of the Trademark Register to protect Alkem's prior rights.
Ovid Therapeutics, Inc. v.Assistant Controller Of Patents And Designs
Ovid Therapeutics appealed a refusal order issued by the Assistant Controller of Patents and Designs regarding its patent application for 'Methods of Increasing Tonic Inhibition and Treating Secondary Insomnia'. The initial rejection cited multiple grounds, including non-patentability (Section 3(i) and 3(e)), lack of inventive step, and insufficient disclosure. Ovid Therapeutics argued that their composition offered a synergistic effect and provided novel dosage information not present in the prior art. This appeal challenges the Controller's decision to refuse patent protection for the pharmaceutical methods.
Ipca Laboratories Limited v.Amandeep Singh Vohra & Anr.
The Delhi High Court allowed a petition filed by Ipca Laboratories Limited seeking the cancellation of the trademark 'IPKA HEALTHCARE.' This decision was based on a consent decree previously passed by the Bombay High Court, where Respondent No. 1 agreed to remove the impugned mark. The court formally cancelled the registration, reinforcing the principle that prior litigation settlements can drive IP rectification.
M/S. Apex Laboratories Pvt. Ltd. v.M/S. Elder Projects Limited
Apex Laboratories Pvt. Ltd filed a suit against Elder Projects Limited alleging trademark and copyright infringement concerning the use of deceptively similar marks like ZINCODER for pharmaceutical products. The plaintiff sought permanent injunctions, destruction of infringing materials, and damages. However, the parties successfully reached an amicable resolution through mediation.
Vifor International Ltd & Anr. v.MSN Laboratories Pvt Ltd & Anr., Corona Remedies Pvt Ltd, Dr Reddys Laboratories Ltd
Vifor International Ltd challenged an interim injunction order that restricted its patent claims by interpreting product-by-process claims as limited only to the specific manufacturing process. The Delhi High Court addressed this significant issue, clarifying that the scope of a patent claim cannot be unduly narrowed merely because it is described using a 'product-by-process' format. The court emphasized that claim construction must define the full scope of protection granted by the patent, allowing the suit proceedings to continue based on this clarified legal position.
