The Madras High Court has clarified that in passing off actions, the absence of direct proof of counterfeiting does not defeat a claim if the cumulative circumstances reasonably indicate a likelihood of consumer confusion. This judgment reinforces the principle that protection of trademark goodwill hinges on market perception, not forensic certainty.
Background & Facts
The Dispute
The appellant, Rubinetterie Bresciane Bonomi SpA, an Italian manufacturer of brass plumbing products, held registered trademarks "RB" and "Rubinetterie Bresciane". The respondent, Lehry Instrumentation & Valves Pvt. Ltd., was its authorised distributor in India for several years. The relationship deteriorated after the appellant received customer complaints that products bearing its trademarks were inferior and not manufactured by it. The appellant terminated the distributorship on 08.07.2014 and issued communications to customers warning against dealing with the respondent. The respondent, in turn, sued for defamation, alleging the communications damaged its reputation.
Key Facts
- The appellant has been using the trademarks "RB" (in a diamond-shaped device) and "Rubinetterie Bresciane" since at least 2005.
- The respondent acknowledged the appellant’s prior adoption and use of the trademarks during cross-examination.
- The respondent had access to the appellant’s invoices, catalogues, and quality certification documents during the distributorship.
- Customer complaints received in early 2014 included invoices and quality certificates for products bearing the appellant’s mark, which were later found to be internally generated by the respondent.
- Email dated 13.06.2014 (Ex.P-13) showed the respondent generating quality certificates based on the appellant’s templates.
- Invoices marked Ex.P-15 (dated 11.03.2014, 04.04.2014, 07.05.2014) showed sale of 65 mm Pressure Reducing Valves, which the appellant confirmed it never manufactured or supplied.
- The respondent sourced similar products from undisclosed manufacturers, including in China, and refused to disclose their identities, citing "business secret".
- The respondent filed an application with the Trade Marks Registry on 15.01.2014 seeking registration of the "RB" mark in its own name, claiming prior use, and withdrew it on 05.03.2014.
- The appellant filed C.S.No.405 of 2014 on 21.06.2014 seeking injunction and damages.
- The respondent filed C.S.No.891 of 2015 on 15.09.2015 seeking damages of Rs.50 lakhs and injunction against the appellant’s communications.

The Parties' Positions
Appellant (Plaintiff in C.S.405/2014): Argued that the respondent’s conduct - generating fake certificates, sourcing identical products from undisclosed manufacturers, misrepresenting product specifications, and attempting to register the appellant’s mark - created a likelihood of confusion. Relied on Cadila Health Care Ltd. v. Cadila Pharmaceuticals Ltd., Laxmikant V. Patel v. Chetanbhai Shah, and BCH Electric Ltd. v. Eaton Corporation.
Respondent (Plaintiff in C.S.891/2015): Contended that the appellant failed to produce any counterfeit product, lacked conclusive evidence, and that the communications were defamatory. Argued that the appellant’s failure to prove counterfeiting rendered its statements false and actionable.
Relief Sought
Appellant: Permanent injunction against use of its trademarks, disclosure of manufacturers, seizure and destruction of counterfeit goods, and damages of Rs.10,00,000.
Respondent: Permanent injunction against the appellant’s communications, damages of Rs.50 lakhs for loss of reputation, and costs.
The Legal Issue
The central question was whether a plaintiff in a passing off action must prove actual counterfeiting by direct evidence, or whether a likelihood of confusion arising from cumulative circumstantial evidence suffices to establish liability.
Arguments Presented
For the Appellant
The appellant argued that the respondent’s conduct - generating false quality certificates, sourcing identical products from undisclosed manufacturers, selling products not manufactured by the appellant under its trademark, and attempting to register the trademark - collectively created a likelihood of deception. Relied on Cadila Health Care Ltd. v. Cadila Pharmaceuticals Ltd. and Laxmikant V. Patel v. Chetanbhai Shah to assert that fraud is not required, and that the test is likelihood of confusion. Highlighted that the respondent’s refusal to disclose manufacturers and its internal generation of certification documents constituted misrepresentation. Emphasised that discrepancies in dates were clerical and explained by witness testimony.
For the Respondent
The respondent contended that the appellant failed to produce any counterfeit product, lacked technical analysis, and relied on documents with inconsistencies. Argued that the absence of conclusive proof of counterfeiting rendered the appellant’s allegations baseless. Asserted that the communications issued by the appellant were defamatory because they falsely accused the respondent of selling counterfeit goods without substantiation.
The Court's Analysis
The Court conducted a comprehensive review of the evidence and rejected the Single Judge’s narrow approach requiring conclusive proof of counterfeiting. It held that in passing off actions, the focus is on whether the defendant’s conduct is likely to cause confusion in the course of trade, not on proving actual fraud or producing physical counterfeit goods.
"The settled position is that such cases are to be decided on the basis of whether the conduct complained of is likely to result in misrepresentation and consequent confusion in the course of trade, on an overall assessment of the evidence and on the standard of preponderance of probabilities."
The Court found that the respondent’s internal generation of quality certificates (Ex.P-13) created a false impression of authenticity. The invoices (Ex.P-15) showing sale of 65 mm Pressure Reducing Valves - products the appellant never manufactured - constituted clear misrepresentation. The respondent’s refusal to disclose the source of similar products, coupled with its attempt to register the appellant’s trademark, demonstrated a pattern of conduct aimed at usurping goodwill.
The Court distinguished between the burden of proof in criminal counterfeiting and civil passing off, noting that the latter requires only a likelihood of confusion. It cited Cadila Health Care to affirm that in India, where literacy levels vary and consumers may not discern fine distinctions, phonetic or visual similarity coupled with contextual misrepresentation suffices.
The Court also found the Single Judge erred in dismissing Ex.P-10 and Ex.P-15 on procedural grounds. The absence of official translation was a curable defect, and the dates in Ex.P-9 were clearly typographical errors, as confirmed by witness testimony. The Court held that the respondent’s conduct, when viewed cumulatively, met the threshold for passing off.
Regarding defamation, the Court held that the appellant’s communications were issued in good faith to protect its commercial reputation after receiving credible complaints. The absence of proof of actual damage to the respondent’s business rendered the award of Rs.10,00,000 unsustainable.
The Verdict
The appellant succeeded in part. The Court set aside the judgment dated 29.11.2019 and partly decreed C.S.No.405 of 2014 by granting an injunction restraining the respondent, its agents, and persons claiming through it from using the appellant’s trademarks or any deceptively similar mark in a manner likely to represent its goods as those of the appellant. The claim for damages by the appellant was rejected. The decree for damages of Rs.10,00,000 in favour of the respondent in C.S.No.891 of 2015 was set aside. The appellant is permitted to withdraw the amounts deposited in O.S.A.Nos.241 & 255 of 2020, along with accrued interest. There shall be no order as to costs.
What This Means For Similar Cases
Likelihood of Confusion Is Sufficient Without Physical Evidence
- Practitioners need not produce counterfeit goods to establish passing off; circumstantial evidence such as false certifications, undisclosed sourcing, and misrepresentation of product specifications suffices.
- Courts must assess the cumulative effect of conduct, not isolate individual inconsistencies.
- The burden shifts to the defendant to explain suspicious conduct, especially when it involves access to the plaintiff’s proprietary materials.
Good Faith Communications Are Not Automatically Defamatory
- Communications issued to protect brand integrity after receiving credible complaints are protected if made in good faith.
- Damages for defamation require proof of actual loss; mere allegations of reputational harm without quantified evidence will not sustain an award.
- A failed passing off claim does not automatically render related communications defamatory - each must be judged independently on context and justification.
Procedural Defects Are Curable in Civil Trademark Disputes
- Absence of certified translations or non-examination of report authors does not justify outright rejection of evidence if the content is reliable and unchallenged on substance.
- Clerical errors in dates or invoice numbers must be evaluated in light of witness explanations and overall context.
- Courts must avoid overly technical rejections that undermine substantive justice in commercial disputes.
The Burden of Secrecy Cannot Shield Misconduct
- Invoking "business secret" to withhold information about sourcing of competing products is not a valid defence when such sourcing coincides with use of another’s trademark.
- Refusal to disclose suppliers under such circumstances raises a legitimate inference of misrepresentation.
Trademark Registration Attempts Are Relevant Evidence
- Filing an application to register another’s trademark - even if later withdrawn - is admissible as evidence of intent to usurp goodwill.
- Such conduct, when combined with other acts of misrepresentation, strengthens the case for passing off.
The Standard Is Preponderance of Probabilities, Not Beyond Reasonable Doubt
- Civil trademark disputes are decided on balance of probabilities, not criminal standards.
- Courts must avoid requiring forensic-level proof in passing off cases, which are inherently about market perception.
The Role of Consumer Perception in India
- Courts must account for India’s diverse literacy levels and consumer behaviour.
- Phonetic similarity, packaging resemblance, and contextual misrepresentation may cause confusion even where marks are not identical.
- The Cadila Health Care standard applies broadly, even to non-medicinal goods, where consumer protection is paramount.
Practical Takeaways for Practitioners
- In passing off suits, focus on: (a) prior rights, (b) likelihood of confusion, (c) defendant’s conduct, and (d) market impact.
- Collect and preserve: invoices, emails, certification documents, trademark applications, and customer complaints.
- Avoid over-reliance on physical evidence; build a narrative of cumulative misrepresentation.
- In defamation claims arising from trademark disputes, establish good faith and reasonable basis for communication.
- Always request injunctions early - irreparable harm is presumed in passing off.
Case Citation Reminder
- Cadila Health Care Ltd. v. Cadila Pharmaceuticals Ltd. [(2001) 5 SCC 73]
- Laxmikant V. Patel v. Chetanbhai Shah [(2002) 3 SCC 65]
- BCH Electric Ltd. v. Eaton Corporation [(2016) SCC OnLine Del 3639]
- Ruston & Hornsby Ltd. v. Zamindara Engineering Co. [(1969) 2 SCC 727]
These authorities now form the definitive framework for assessing passing off in Indian commercial litigation.
Final Note
This judgment is a landmark in Indian trademark jurisprudence. It aligns Indian practice with global standards by affirming that trademark protection is not contingent on proving criminal counterfeiting, but on preventing consumer deception. Practitioners must now frame passing off claims with greater emphasis on market conduct and consumer perception, not forensic evidence.
