Two Piscos, One Bar: Delhi High Court Division Bench Confirms Dual GI Identity for Peru and Chile

Two bottles and two glasses of Pisco labeled "Peruvian Pisco" and "Chilean Pisco" are displayed on a table set against a scenic vineyard backdrop at sunset, symbolizing the geographical indication dispute between Peru and Chile.

What began as a routine GI application in 2005 ended twenty years later with Delhi High Court’s Division Bench settling one of Indian IP law’s most contested geographical indication disputes. Can Peru hold “PISCO” exclusively – or must two countries share a five-letter word?

KENT can’t do it! Court proves it’s not a big FAN of Kent’s Brand Stretch, backs prior use

In the case of Kent Ro Systems Limited v. Kent Cables Private Limited, two businesses using the same mark KENT clashed over who could sell fans under that mark. One side relied on its strong reputation in water purifiers and home appliances. The other relied on earlier adoption of KENT for electrical goods and evidence of fan sales over several years. The Division Bench upheld the interim restraint against Kent RO and left the final rights to be decided at trial.

No double riding! Court clarifies on patent revocation plea in case involving Philips

In the case of Versuni Holding B.V. Trading as Preethi v. Maya Appliances Private Limited, the patent holder had already sued for infringement before the Delhi High Court. The alleged infringer then filed a written statement there seeking invalidity and revocation of the patent, but also filed a separate revocation petition before the Madras High Court. The Madras High Court dismissed that separate revocation petition and accepted the objection to its maintainability.

In the case of Volkswagen AG v. The Registrar of Trade Marks and Anr., Volkswagen opposed Maruti Suzuki’s application for TRANSFORMOTION in Class 12 on the ground that it was too close to Volkswagen’s earlier mark 4MOTION. The court examined the marks in the setting in which they were used, noted that one was tied to a vehicle technology and the other to an advertising campaign, and concluded that the two marks did not create deceptive similarity.

Mere Admixture or True Innovation? Crystal Crop’s Herbicidal Composition Fails the Synergy Test

The Delhi High Court has reaffirmed a simple patent lesson: mixing known compounds will not do unless the mix delivers something unexpectedly better. In Crystal Crop, the claimed herbicidal composition failed that test.

In the case of Daikin Industries Ltd. v. Assistant Controller of Patents and Designs, the Indian Patent Office refused Daikin’s patent application relating to a shell and plate heat exchanger on the ground of lack of novelty over a prior art document. During the appeal before the High Court, Daikin sought permission to amend claim 1 by incorporating additional limitations already disclosed in the specification. The court examined whether such an amendment could be permitted at the appellate stage under Section 59 of the Patents Act.

Can Anyone Own the “Forest”? Delhi High Court Applies Anti Dissection Rule in Forest Essentials case

The Delhi High Court recently refused to grant an interim injunction in the dispute between Forest Essentials and Baby Forest Ayurveda. The court held that “BABY FOREST” was not deceptively similar to “FOREST ESSENTIALS,” and that the word **“FOREST,” being a dictionary word, could not be monopolised without strong evidence of secondary meaning. Applying the anti dissection rule, the court concluded that the marks must be assessed as a whole and declined to interfere with the Single Judge’s refusal of interim relief.

In the case of Energeo Works India Private Limited v. Assistant Controller of Patents, the Patent Office refused a patent application relating to an air cooling system that used a mist of water to pre cool ambient air entering an air cooled chiller assembly. The refusal was based on lack of inventive step in view of two prior art documents and common general knowledge. The applicant challenged the refusal on the ground that the order was unreasoned and that the Controller had not applied the correct legal test for obviousness.

Wanted Dead or Alive: Delhi High Court Holds Patent Revocation Survives Expiry and Section 107 Defence

In the case of Boehringer Ingelheim Pharma GmbH & Co. KG v. Controller of Patents & Anr., the Delhi High Court addressed two important questions under the Patents Act: whether a revocation petition survives patent expiry, and whether it can continue after a Section 107 invalidity defence is raised in an infringement suit. The dispute arose from parallel revocation and infringement proceedings relating to Patent IN 243301 covering Linagliptin. The court held that revocation under Section 64 remains maintainable despite patent expiry and is not barred by a Section 107 defence.
