Showing 91–119ITC Limited v.The Controller of Patents Designs and Trademark

The Controller had rejected the invention on grounds that its use could cause serious prejudice to human health or public order. ITC argued that the rejection was arbitrary, lacked reasoned basis, and violated principles of natural justice due to the introduction of unsupplied documents. The Calcutta High Court set aside the impugned order, remanding the matter back to the Controller for a fresh decision after ensuring all parties are heard.

The petitioner demonstrated long-standing use and exclusive association with their distinctive packaging designs for tea. The court found that the respondent's design was deceptively similar, noting only cosmetic changes while retaining the core features and color scheme. Consequently, the registration of the impugned artistic work was directed to be expunged.

The core dispute centered on whether the amendment—specifically changing the claim from a method to a system—was permissible under the law. The Calcutta High Court found serious infirmities in the Controller's order, noting that it failed to properly assess if the amendments broadened the scope beyond the original specification. Consequently, the court set aside the rejection and remanded the matter for fresh adjudication on the merits.

Consequently, the court allowed the application seeking revocation of dispensation.

The plaintiff alleged trademark and copyright infringement against Anita Anu for using the deceptively similar mark 'Poly Punkaj'.

Pankaj Plastic Industries Private Limited v.Anita Anu
This case involved a dispute over trademarks and copyright infringement concerning plastic products marketed under 'Pankaj Flex' by the plaintiff.

The court scrutinized the nine-month delay between the alleged date of knowledge (January 2024) and the filing of the suit (September 2024).

This case before the Calcutta High Court concerned an application by Pankaj Plastic Industries Private Limited seeking to revoke a dispensation granted under Section 12A of the Commercial Courts Act, 2015. The plaintiff alleged trademark and copyright infringement by the defendant using the mark 'Poly Punkaj'. However, the court found that the plaintiff failed to provide adequate justification for the nine-month delay between becoming aware of the issue (January 2024) and filing the suit (September 2024). Citing precedents, the judge held that without a clear explanation for the delay, the urgency was artificially created, leading to the revocation of the dispensation.
Upl Ltd v.The Controller Of Patents Designs And Trademark
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. The Calcutta High Court found that the original order lacked proper analysis of the experimental data supporting synergy and noted procedural lapses by the Controller in failing to issue a Second Examination Report (SER). Consequently, the court set aside the rejection order and remanded the matter for fresh consideration.
ITC Limited v.The Controller of Patents, Designs & Trademark
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.

The Calcutta High Court ultimately set aside the impugned order, finding the sole ground for rejection untenable, and remanded the matter to a new Hearing Officer.
