A hand writing the word “SYNERGY” above the equation “1 + 1 > 2” in red marker, illustrating the concept that combined elements can produce a greater effect than their individual contributions.

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.

The court examined whether such an amendment could be permitted at the appellate stage under Section 59 of the Patents Act.

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.

Ideas Fly, Adoption Walks: Why New Technology Still Takes Its Own Sweet Time

WIPO’s World Intellectual Property Report 2026 makes one point painfully clear: ideas move fast, but adoption still depends on unglamorous complements like skills, infrastructure, and maintenance. India’s examples show why diffusion is an execution game, not a press-release game.

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.
