Sarepta Therapeutics, Inc. et al. v.Genzyme Corporation et al.
Sarepta Therapeutics has filed an IPR petition challenging Genzyme’s ’894 patent covering analytical ultracentrifugation methods for AAV vectors. The petitioner asserts that the claims are obvious in view of long‑standing literature (de la Maza) and the Le Bec patent, combined with Sommer and Cole. The petition seeks institution and cancellation of claims 1‑7 and 10‑30.
Eoptolink Technology USA Inc. et al. v.Applied Optoelectronics, Inc.

Sarepta Therapeutics, Inc. et al. v.Genzyme Corporation et al.

Suinno Mobile & AI Technologies Licensing Oy v.Microsoft Corporation
Suinno sought suspensive effect under R. 223 RoP to prevent enforcement of a cost decision (R. 151 RoP) issued by the Central Division (Paris Seat) ordering it to pay €350,000.00 in costs to Microsoft following a default judgment dismissing Suinno's infringement action concerning EP 2 671 173. The Court of Appeal held that while the application was admissible, Suinno failed to demonstrate exceptional circumstances justifying suspensive effect, as it had not shown the cost decision was manifestly erroneous. The application for suspensive effect was rejected.
Ascendis Pharma A/S et al. v.BioMarin Pharmaceutical Inc.
Ascendis Pharma has filed a PGR petition seeking cancellation of BioMarin’s U.S. Patent 12,331,106 covering CNP‑variant treatments for achondroplasia. The petition alleges obviousness, anticipation, lack of enablement, and an improper dependent claim. The Board must decide whether to institute the review.
Google LLC v.Sonos, Inc.
Google has filed an IPR petition seeking to invalidate Sonos’s multi‑speaker audio patent, arguing that the claims are obvious over existing Bluetooth speaker technologies. The petition requests institution of the review and cancellation of all challenged claims.
Rajani Products v.Madhukar Varandani, Proprietor Of M/S Naturalindia Oils And Proteins & Anr.
Rajani Products filed a petition seeking the removal of a specific Copyright registration (A-128046/2019) held by Madhukar Varandani. The petitioner, engaged in manufacturing edible oils, claimed that their own artistic works and labels, featuring the SWASTIK device, were prior and original. They argued that the impugned work was a substantial reproduction of their protected designs. After comparing the two artistic works, the court found that the Impugned Artistic Work lacked originality and substantially imitated the Petitioner's registered works.
Trident Limited v.Controller Of Patents
Trident Limited appealed a decision by the Controller of Patents that refused grant for its patent application concerning 'Air Rich Yarn and Fabric and its Method of Manufacturing'. The Appellant argued that the refusal, based on lack of inventive step, was flawed because the cited prior art did not disclose the critical feature: uniformly distributed pores across the radial cross-section of the yarn. The Delhi High Court found infirmities in the Impugned Order, particularly regarding the interpretation of novelty and obviousness against the specific claims. Consequently, the High Court set aside the refusal order and remanded the matter for fresh consideration by a different Controller.
Medilabo Rfp Inc v.The Controller Of Patents
Medilabo Rfp Inc appealed the refusal of its patent application for a prophylactic drug composition intended for neurodegenerative diseases. The core dispute centered on whether the claims, which described a chemical composition, could be rejected under Section 3(i) (lack of inventive step/patentability criteria) because they were used for treatment. The High Court found that the Controller failed to address all objections and misinterpreted the scope of the product claim versus its therapeutic application. Consequently, the appeal was successful, leading to the setting aside of the refusal order and remanding the case for fresh consideration.
Amylin Pharmaceuticals, Llc And Anr v.Assistant Controller Of Patents And Designs
Amylin Pharmaceuticals appealed the Assistant Controller's rejection of its patent application for 'RELEASE FORMULATIONS USING NON-AQUEOUS CARRIERS'. The appeal challenged the finding that the invention lacked inventive step and fell under Section 3(d).
F. Hoffmann-La Roche Ag v.Zydus Lifesciences Limited
The Plaintiffs sought exemption from mandatory pre-litigation mediation. The Court disposed of this application as infructuous and noted that the current suit involves the same Suit Patent as another pending infringement suit (CS(COMM) 567/2024). Consequently, both suits were listed together for further proceedings.
Sterlite Technologies Limited v.Aberdare Technologies Private Limited
The plaintiff filed a suit seeking permanent injunction and damages for infringement of two patents related to optical fiber production. The defendants filed a counterclaim seeking revocation of these same patents. Both parties subsequently entered into a settlement agreement.
Lmw Limited v.Marzoli Machines Textile S. R. L & Anr.
Lmw Limited filed a petition before the Delhi High Court seeking the revocation of Indian Patent number IN 496349. The court issued notice and directed both parties to file necessary pleadings, setting future dates for listing.
M/S Veerji Restaurant Private Limited v.Mohini Chaddha Trading As Veerj Ji Malai Chaap Wale & Ors.
The Delhi High Court addressed several applications in the trademark dispute, notably vacating an earlier ad-interim ex-parte injunction order against Defendant No. 2. The court found that the plaintiff had obtained the injunction by presenting inaccurate facts regarding the termination of a franchise agreement. Furthermore, the disputes between the original parties (Plaintiff and Defendant No. 2) were referred to arbitration. Separately, the Court allowed additional documents for evidence while permitting Defendants No. 3 and 4 to join proceedings after recalling an ex-parte order.
Ashim Kumar Ghosh v.The Registrar Of Trade Marks
The Delhi High Court allowed an appeal filed by Ashim Kumar Ghosh against the Registrar of Trade Marks' refusal to register the mark 'SoEasy'. The core issue was whether the mark, used for instructional and teaching material, possessed sufficient distinctiveness. The court ruled that 'SoEasy' is a suggestive mark—requiring consumers to use imagination and thought to connect it to educational products—and therefore qualifies for protection under the Trade Marks Act. Consequently, the Registrar was directed to proceed with the registration of the mark.
Fdc Limited v.Healing Pharma India Private Limited
Fdc Limited filed a suit against Healing Pharma India Private Limited alleging multiple infringements related to its pharmaceutical products. The Delhi High Court issued an order addressing procedural aspects, including granting exemptions from pre-institution mediation and allowing the filing of additional documents. Crucially, the court also addressed interim relief, restraining the defendant from manufacturing or marketing products confusingly similar to Fdc's registered trademarks (ZIFI) and copyrighted trade dress (ELECTRAL).
Dharma Production Private Limited v.Bhallaram Choudhary
The Rajasthan High Court addressed an appeal filed by Dharma Production Private Limited seeking a stay on an injunction preventing the release of their movie, 'Jigra,' due to alleged trademark violation. The court initially found that prima facie, naming a movie does not constitute trademark infringement when the appellant is not trading in goods or services under that name. However, given that the film had already been released, the High Court ultimately disposed of the appeal while directing the Trial Court to proceed with the temporary injunction application and the main suit strictly according to law.
Amazon.com Services LLC v.Smart Speaker LLC
Amazon has filed an IPR petition challenging Smart Speaker's ’590 patent covering smart‑meter appliances. The petition alleges obviousness over multiple prior‑art references for all 62 claims. The Board has not yet ruled on the petition.

The order, issued by Judge-rapporteur András Kupecz following an interim conference on 21 November 2025, sets the value of the case at EUR 1,000,000, grants the Defendant time to clarify its requests, and confirms the date of the oral hearing for 15 January 2026 in Munich.
