Madras High Court Upholds Trademark Rights in "RB" Case, Sets Aside Defamation Damages

Injunctive relief granted to Rubinetterie Bresciane Bonomi SpA; defamation claims by Lehry Instrumentation & Valves Pvt. Ltd. overturned


In a significant ruling, the Madras High Court has delivered judgment in the case of Rubinetterie Bresciane Bonomi SpA versus Lehry Instrumentation & Valves Pvt. Ltd., concerning trademark infringement and defamation claims. The court has partly decreed in favor of Rubinetterie Bresciane Bonomi SpA, granting injunctive relief against Lehry Instrumentation & Valves Pvt. Ltd., while setting aside the damages awarded for defamation.


The case revolved around allegations of passing off counterfeit products under the trademark "RB" and "Rubinetterie Bresciane." Rubinetterie Bresciane Bonomi SpA claimed that its former distributor, Lehry Instrumentation & Valves Pvt. Ltd., was misrepresenting goods and circulating counterfeit products bearing its trademark. The appellant sought an injunction and damages for these alleged activities.


The Division Bench, comprising Mr. P. Velmurugan and Mr. K. Govindarajan Thilakavadi, J.J., examined the evidence presented, including admissions by the respondent, invoices, and quality certification documents. The court noted that the cumulative evidence indicated a likelihood of misrepresentation and confusion among consumers regarding the origin of the goods, which warranted injunctive relief.


However, the court found that the appellant did not conclusively prove actual counterfeiting, which is not a necessity in passing off actions. The standard of proof in such cases is based on the likelihood of confusion or deception on a preponderance of probabilities. Therefore, the appellant's claim for damages was rejected due to the absence of clear evidence of quantifiable loss.


In parallel, Lehry Instrumentation & Valves Pvt. Ltd. had filed a suit claiming defamation damages, alleging that communications issued by Rubinetterie Bresciane Bonomi SpA were false and damaging to its reputation. The High Court set aside the damages awarded to the respondent, citing insufficient proof of actual loss of reputation or business directly caused by the communications.


The court emphasized that statements made in good faith for the protection of legitimate commercial interests and based on reasonable apprehension do not typically constitute actionable defamation. The judgment considered the context and intention behind the communications, noting the absence of convincing material demonstrating actual harm.


This judgment reinforces the principles governing trademark protection and passing off actions, highlighting the importance of evidence in establishing likelihood of confusion. It also underscores the need for careful consideration in defamation claims, particularly when dealing with commercial communications intended to safeguard brand reputation.


The appeals in O.S.A.No. 241 of 2020 and O.S.A.No. 255 of 2020 resulted in partial success for Rubinetterie Bresciane Bonomi SpA, with the court permitting withdrawal of deposited amounts related to the case. The court's decision marks a crucial precedent in trademark law, emphasizing protection against misrepresentation and the nuances of defamation claims.


Bottom line:-

Trademark Law - Passing off - Likelihood of confusion and misrepresentation of trademark "RB" and "Rubinetterie Bresciane" - Protection of goodwill and prevention of deception among consumers - Injunctive relief granted to stop continued misrepresentation.


Statutory provision(s): Trademark Law, Passing off, Defamation
