Kao Corporation v. The Controller Of Patents & Anr.

Eris Lifesciences LimitedvsController Of Patents & Anr.

This judgment addresses applications filed by Respondent No.2 (Patentee) seeking dismissal of revocation petitions on the grounds of being time-barred. The court held that since no specific limitation is prescribed for revocation under Section 64, a three-year limitation period cannot be read into the provision. Furthermore, interim stay applications were dismissed as the patent was already granted and injunctions had been granted elsewhere.

M/S.Sakthi Sai Safety Glass India & Sakthi Sai Glass Traders (Appellants)vsCompagnie De Saint-Gobain & Saint-Gobain India Private Limited (Respondents/Plaintiffs)

The Madras High Court dismissed appeals challenging an interim injunction granted to Saint-Gobain against Sakthi Sai Safety Glass India. The court found that the appellants, despite their contract with Saint-Gobain expiring, were infringing the 'Saint-Gobain' trademark by using it in connection with toughened glass products. Given the prima facie evidence of consumer confusion and dilution, the balance of convenience favored the trademark owner, upholding the injunction while allowing the main suit to proceed.

Baxalta IncorporatedvsThe Controller Of Patents

Baxalta Incorporated appealed a decision by the Assistant Controller of Patents which refused their application for "FACTOR VIII POLYMER CONJUGATES" due to lack of novelty and inventive steps in product claims. The appellant sought leave to submit an auxiliary claim set restricting the scope to method claims. The High Court allowed this submission, setting aside the impugned order and remanding the matter for fresh consideration.

Yashoda Hospital And Research Center LimitedvsYashoda Super Specialty Hospital And Anr

The Delhi High Court allowed a review petition filed by Yashoda Hospital And Research Center Limited against an order from the Intellectual Property Appellate Board (IPAB). The IPAB had previously allowed a rectification petition, effectively invalidating the petitioner's registered trademark. The court found that the original order violated the principles of natural justice because service of notice was not properly effected on the petitioner. Consequently, the High Court quashed the impugned order and directed that the rectification petition be heard afresh before the Intellectual Property Division (IPD) of the Court.

Madhu Food ProductsvsSurya Processed Food Pvt. Ltd.

The Delhi High Court dismissed the appeal filed by Madhu Food Products, upholding the Commercial Court's initial order favoring Surya Processed Food Pvt. Ltd. The dispute centered on alleged trademark infringement and passing off concerning food products under the marks 'HUNK' and 'HUNT'. The court found prima facie evidence that the appellant copied the respondent's distinctive trade dress and packaging, concluding that the use of 'HUNT' was intended to take advantage of the respondent's established goodwill. This judgment reinforces the importance of protecting brand identity through both trademark registration and distinct visual presentation.
