Calcutta High Court · 64194527

Aroa Biosurgery Limited challenged an order by the Controller General of Patents which dismissed its patent application for 'Tissue Scaffolds Derived From Forestomach Extracellular Matrix.'

The Calcutta High Court found that the impugned order lacked reasons and violated principles of natural justice.

Upl Ltd v.The Controller Of Patents Designs And Trademark

Calcutta High Court · 197814319

Upl Ltd challenged the rejection of its patent application concerning a novel agrochemical fungicide combination. The core dispute centered on whether adding a multi-site fungicide to existing SDHI combinations provided a synergistic and unexpected technical advantage, or if it was merely an obvious aggregation of known substances.

Calcutta High Court · 106547680

ITC Limited appealed the rejection of its patent application for a novel chemical-based nicotine aerosol delivery device. The Controller had rejected the application, citing public health concerns related to nicotine and referencing various statutes. ITC argued that since the device operates purely through a chemical reaction without electrical components, it should not be classified as an ENDS or e-cigarette. The Calcutta High Court ultimately ruled in favor of ITC Limited, emphasizing international IP principles (TRIPS and Paris Convention) which mandate that patentability cannot be denied merely because commercial exploitation is restricted by domestic law.
