Details<\/a><\/li><\/ul><\/nav><\/div>\n\n\n\n\n<p class=\"wp-block-paragraph\">Yet, the law cannot be stretched beyond its limits on the mere invocation of public interest, especially when the party claiming to protect public interest has itself admitted it suffered no commercial loss and produced no credible evidence of any real confusion in the marketplace.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Delhi High Court&#8217;s Division Bench judgement delivered on May 29, 2026, in <strong>Intas Pharmaceuticals Limited versus Sun Pharma Laboratories Limited<\/strong> is a landmark ruling that settles several important questions about how trademark infringement cases involving pharmaceutical products must be tried, what evidence must be led, and how courts must assess deceptive similarity between drug brand names at the post-trial stage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court reversed a permanent injunction that had been granted against Intas Pharmaceuticals and, in doing so, laid down important principles that will guide pharmaceutical trademark litigation in India for years to come.<\/p>\n\n\n\n<h2 id=\"h-factual-and-procedural-background\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Factual_and_Procedural_Background\"><\/span>Factual and Procedural Background<span

id=\"Intas_Pharmaceuticals_and_BEVATAS\"><\/span>Intas Pharmaceuticals and BEVATAS<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Intas Pharmaceuticals Limited is a large multinational pharmaceutical company operating across multiple therapeutic segments, including oncology.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In 2016, Intas launched an anti-cancer drug under the brand name <strong>BEVATAS<\/strong>. This drug contains the molecule bevacizumab, which is a monoclonal antibody\u2014a biological drug used as a first line of treatment for several serious cancers including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Colorectal cancer<\/li>\n\n\n\n<li>Ovarian cancer<\/li>\n\n\n\n<li>Cervical cancer<\/li>\n\n\n\n<li>Lung cancer<\/li>\n\n\n\n<li>Metastatic breast cancer<\/li>\n\n\n\n<li>Recurrent glioblastoma<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The drug was approved by the Drug Controller General of India before its launch, went through rigorous clinical trials, and is administered intravenously only in hospital oncology settings by trained oncology nurses under the supervision of an oncologist.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By the time this appeal was heard, BEVATAS had become the market leader among drugs containing bevacizumab in India, with approximately 22 per cent market share, having been administered to over 75,000 cancer patients, with about 12,000 patients currently undergoing treatment with the drug.<\/p>\n\n\n\n<h3 id=\"h-origin-of-the-name-bevatas\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Origin_of_the_Name_BEVATAS\"><\/span>Origin of the Name BEVATAS<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The name BEVATAS was coined by Intas by combining the following:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Component<\/th><th>Source<\/th><th>Explanation<\/th><\/tr><\/thead><tbody><tr><td>BEVA<\/td><td>Bevacizumab<\/td><td>Taken from the first part of the molecule name<\/td><\/tr><tr><td>TAS<\/td><td>INTAS<\/td><td>Derived from the corporate name INTAS<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 id=\"h-sun-pharma-and-bevetex\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Sun_Pharma_and_BEVETEX\"><\/span>Sun Pharma and BEVETEX<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Sun Pharma Laboratories Limited is the registered proprietor of the trademark <strong>BEVETEX<\/strong>, which it applied for registration back in 1983, receiving the certificate of registration in 1990 under Class 5 of the Trade Marks Register.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, Sun Pharma admittedly did not actually use the mark BEVETEX for over three decades. It began commercially using BEVETEX only in 2015 for its own anti-cancer drug, which contains an entirely different molecule called &#8216;paclitaxel&#8217;.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Paclitaxel is a synthetic chemical cytotoxic agent, not a biological drug. It is used as a second line of treatment\u2014that is, only after a patient&#8217;s combination chemotherapy has failed, or after a relapse within six months of adjuvant chemotherapy\u2014and only for metastatic breast cancer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sun Pharma&#8217;s drug BEVETEX is thus fundamentally different in the following ways:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Composition<\/li>\n\n\n\n<li>Indication<\/li>\n\n\n\n<li>Mechanism of action<\/li>\n\n\n\n<li>Stage of treatment<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These distinctions clearly separate it from Intas&#8217;s drug BEVATAS.<\/p>\n\n\n\n<h3 id=\"h-comparison-between-bevatas-and-bevetex\" class=\"wp-block-heading\"><span

class=\"wp-block-paragraph\">Within just about one year of Sun Pharma launching BEVETEX in 2015, Intas launched BEVATAS in October 2016.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sun Pharma learnt about Intas&#8217;s trademark application for BEVATAS in October 2016 and filed an opposition before the Trademark Registry on December 27, 2016.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Claiming to have gained knowledge of the actual product only in October 2017, Sun Pharma instituted a suit before the Additional District Judge, South-East District, Saket Courts, Delhi, in December 2017, being CS (COMM) No. 39 of 2021, alleging the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Trademark infringement<\/li>\n\n\n\n<li>Passing off<\/li>\n\n\n\n<li>Unfair competition<\/li>\n\n\n\n<li>Misappropriation of goodwill and reputation<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Sun Pharma also sought the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Permanent injunction<\/li>\n\n\n\n<li>Damages<\/li>\n\n\n\n<li>Rendition of accounts<\/li>\n\n\n\n<li>Costs<\/li>\n<\/ul>\n\n\n\n<h3 id=\"h-interim-injunction-stage\"

class=\"wp-block-paragraph\">The Trial Court, vide a detailed order dated September 17, 2018, dismissed Sun Pharma&#8217;s application for an interim injunction, holding that the marks BEVATAS and BEVETEX were structurally, phonetically, and visually different and that no prima facie case of infringement or passing off was made out in view of the distinctions in the character, mode of administration, and other distinct factors of the two drugs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This order was upheld by an appellate bench of the Delhi High Court on January 9, 2020, and Sun Pharma&#8217;s special leave petition before the Supreme Court of India was dismissed on February 14, 2020.<\/p>\n\n\n\n<h3 id=\"h-trial-before-the-ip-division\" class=\"wp-block-heading\"><span

completion of evidence and trial, and after the valuation of the suit&#8217;s reliefs was enhanced, the matter was transferred to the Original Side IP Division of the Delhi High Court.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During the trial, Sun Pharma gave up its claim for damages, rendition of accounts, and all monetary reliefs, taking the stand that it was prosecuting the suit solely in public interest and had no commercial interest.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Only the prayer for a permanent injunction restraining Intas from using the mark BEVATAS was pressed before the learned Single Judge.<\/p>\n\n\n\n<h3 id=\"h-single-judge-decision\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Single-Judge_Decision\"><\/span>Single-Judge Decision<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The learned Single Judge, by the impugned judgement dated March 28, 2026, decreed the suit in favour of Sun Pharma and permanently restrained Intas from using the mark BEVATAS, holding it to be deceptively similar to BEVETEX and likely to cause confusion in the minds of consumers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Aggrieved by this order, Intas filed the present Regular First Appeal before the Division Bench under Section 96 of the Code of Civil Procedure, 1908.<\/p>\n\n\n\n<h2 id=\"h-the-dispute\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_Dispute\"><\/span>The Dispute<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The core dispute before the Division Bench was whether the learned Single Judge was justified in granting a permanent injunction against Intas on the ground that BEVATAS was deceptively similar to BEVETEX and likely to cause confusion among the public.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Several sub-issues arose:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Whether Sun Pharma&#8217;s plaint was properly framed and disclosed a legitimate cause of action.<\/li>\n\n\n\n<li>Which specific provision of Section 29 of the Trade Marks Act, 1999, governed the dispute.<\/li>\n\n\n\n<li>Whether the two drugs were similar or dissimilar goods.<\/li>\n\n\n\n<li>Whether the two trademarks were visually, structurally, or phonetically similar.<\/li>\n\n\n\n<li>Whether Sun Pharma had actually led any credible evidence to prove likelihood of confusion among the relevant class of the public.<\/li>\n\n\n\n<li>Whether the learned single judge&#8217;s approach of deciding infringement purely on a visual and phonetic comparison of marks at the post-trial stage was legally sustainable.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"h-reasoning-and-analysis-of-the-court\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Reasoning_and_Analysis_of_the_Court\"><\/span>Reasoning and Analysis of the Court<span

class=\"ez-toc-section\" id=\"On_the_Vexatious_Nature_of_the_Plaint_Regarding_Passing_Off_and_Unfair_Competition\"><\/span>On the Vexatious Nature of the Plaint Regarding Passing Off and Unfair Competition<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The court noted that Sun Pharma&#8217;s plaint was framed in the broadest possible manner, pleading multiple causes of action, including trademark infringement, passing off, unfair competition, and misappropriation of goodwill, and seeking monetary damages and rendition of accounts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Yet, soon after filing the suit, Sun Pharma represented before the trial court, in its rejoinder to the injunction application on January 29, 2018, that it had no commercial interest and was prosecuting the suit purely in public interest because Sun Pharma did not sell any medicine containing the molecule bevacizumab.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This stand was reiterated before the appellate court in FAO 447\/2018, in the evidence affidavit of its sole witness PW-1 dated February 8, 2019, and again in cross-examination.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court held that this admission constituted a clear acknowledgement that Sun Pharma had suffered no commercial loss, no diversion of sales, and no damage to goodwill from Intas&#8217;s use of BEVATAS.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court held that the dissimilarity of the two drugs&#8217; molecules was a fact known to Sun Pharma even before the suit was filed, yet it vexatiously pleaded passing off, misrepresentation, unfair competition, and monetary claims to create an illusion of a cause of action and a false sense of urgency.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court further observed that Sun Pharma ought to have restricted its suit from inception to the narrow claim of infringement based on alleged deceptive similarity and that even at the stage of amendment of the plaint in August 2022 when the pecuniary valuation was enhanced, Sun Pharma did not delete the vexatious pleas it knew to be untenable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court relied on ITC Ltd v. Debts Recovery Appellate Tribunal, (1998) 2 SCC 70, and Bengal Waterproof Limited v. Bombay Waterproof Manufacturing Company and Anr., (1997) 1 SCC 99, to hold that proceeding to trial on such a plaint emboldened dishonest litigants and encouraged frivolous litigation, undermining the sanctity of the Statement of Truth under the Commercial Courts Act, 2015.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Issue<\/th><th>Court&#8217;s Observation<\/th><\/tr><\/thead><tbody><tr><td>Commercial Interest<\/td><td>Sun Pharma admitted it had no commercial interest in the molecule bevacizumab.<\/td><\/tr><tr><td>Passing Off Claims<\/td><td>Held to be vexatiously pleaded despite knowledge of dissimilar products.<\/td><\/tr><tr><td>Monetary Claims<\/td><td>No evidence of loss, diversion of sales, or goodwill damage.<\/td><\/tr><tr><td>Effect on Litigation<\/td><td>Encouraged frivolous litigation and weakened the sanctity of the Statement of Truth.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 id=\"h-on-the-applicable-sub-section-of-section-29-of-the-trade-marks-act-1999\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"On_the_Applicable_Sub-Section_of_Section_29_of_the_Trade_Marks_Act_1999\"><\/span>On the Applicable Sub-Section of Section 29 of the Trade Marks Act, 1999<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The court examined Sun Pharma&#8217;s shifting legal positions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before the single judge, Sun Pharma invoked Section 29(3) of the Act, which creates a statutory presumption of likelihood of confusion. However, this presumption under Section 29(3) is only available when both the marks and the goods are identical, which falls under Section 29(2)(c).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court categorically held that the marks BEVATAS and BEVETEX are not identical, nor are the goods identical. Therefore, Section 29(2)(c) and the presumption of Section 29(3) were wholly inapplicable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court also held that Section 29(4), which deals with dissimilar goods, was inapplicable since Sun Pharma had abandoned its plea of reputation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court concluded that the dispute was squarely governed by Section 29(2)(b) of the Act, which applies where the defendant&#8217;s mark is similar (not identical) to the registered mark and is used in relation to goods that are identical or similar to the goods covered by the registered mark. Under this provision, the burden lay entirely on Sun Pharma to affirmatively prove likelihood of confusion among the public.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court was critical of Sun Pharma&#8217;s vague and overbroad pleading of merely &#8220;Section 29&#8221; without specifying the sub-section, which the court described as inexact, intentional, and mischievous, enabling Sun Pharma to shift its legal arguments across different sub-sections at different stages.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Provision<\/th><th>Court&#8217;s Finding<\/th><\/tr><\/thead><tbody><tr><td>Section 29(2)(c)<\/td><td>Inapplicable because marks and goods were not identical.<\/td><\/tr><tr><td>Section 29(3)<\/td><td>Presumption of confusion unavailable.<\/td><\/tr><tr><td>Section 29(4)<\/td><td>Inapplicable, as the reputation plea was abandoned.<\/td><\/tr><tr><td>Section 29(2)(b)<\/td><td>Held to be the governing provision.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 id=\"h-on-the-evidentiary-standard-and-sun-pharma-s-failure-to-discharge-the-burden\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"On_the_Evidentiary_Standard_and_Sun_Pharmas_Failure_to_Discharge_the_Burden\"><\/span>On the Evidentiary Standard and Sun Pharma&#8217;s Failure to Discharge the Burden<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The court emphasised that in a case where goods are not identical or closely similar, the likelihood of confusion cannot be presumed and must be proved by positive evidence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court drew support from P. Narayanan&#8217;s authoritative commentary on the Law of Trade Marks and Passing Off (Sixth Edition, 2004, paragraph 9.28), which states that where goods are not closely similar in character, evidence of witnesses is necessary to establish whether confusion is likely to occur.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sun Pharma itself had identified the relevant class of persons likely to be confused as being chemists, specifically pleading in paragraph 21(D) of the plaint that a chemist may give out the wrong drug on account of confusion or lack of stock.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court noted that Sun Pharma never even pleaded that an oncologist might be confused at the prescription stage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Despite identifying the chemist as the relevant class of public susceptible to confusion, Sun Pharma examined only a single witness, PW-1, who was its own sales manager.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This witness parroted the plaint and made bald assertions about the likelihood of confusion without any personal knowledge.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In cross-examination, PW-1 admitted:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The drug formulations of BEVATAS and BEVETEX were completely different.<\/li>\n\n\n\n<li>The two drugs were of a very different class of drugs with different indications and modes of action.<\/li>\n\n\n\n<li>The toxicity profiles were different.<\/li>\n\n\n\n<li>There was no actual instance of confusion between the two marks on record.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The only document PW-1 could point to as evidence of confusion was Ex. PW-1\/9, an e-newspaper article about a 2011 incident of gross negligence by a pharmacist involving entirely different drugs. PW-1 admitted that it had nothing to do with BEVATAS or BEVETEX and was merely a general example.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court held that PW-1 was not a competent witness to depose about the likelihood of confusion, as he belonged to a completely different class from chemists, oncologists, and trained nurses.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court held PW-1&#8217;s testimony to be unreliable and discarded it entirely.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In contrast, Intas&#8217;s witness DW-1 deposed that the drugs were administered under strict medical supervision in specialised oncological settings and that the possibility of confusion was negligible, testimony that remained largely uncontroverted in cross-examination.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Witness<\/th><th>Key Evidence<\/th><th>Court&#8217;s Assessment<\/th><\/tr><\/thead><tbody><tr><td>PW-1 (Sun Pharma)<\/td><td>General assertions regarding confusion; no actual instances proved.<\/td><td>Testimony discarded as unreliable.<\/td><\/tr><tr><td>DW-1 (Intas)<\/td><td>Explained specialised administration and low risk of confusion.<\/td><td>Remained largely unchallenged.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 id=\"h-key-takeaways-from-the-court-s-analysis\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Key_Takeaways_from_the_Courts_Analysis\"><\/span>Key Takeaways from the Court&#8217;s Analysis<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sun Pharma&#8217;s broader claims of passing off, unfair competition, and monetary relief were viewed as vexatious and unsupported.<\/li>\n\n\n\n<li>The dispute was governed by Section 29(2)(b) of the Trade Marks Act, 1999.<\/li>\n\n\n\n<li>The statutory presumption of confusion under Section 29(3) was unavailable.<\/li>\n\n\n\n<li>The burden of proving likelihood of confusion rested entirely on Sun Pharma.<\/li>\n\n\n\n<li>Sun Pharma failed to produce competent evidence from the relevant class of consumers or professionals.<\/li>\n\n\n\n<li>No actual instance of confusion between BEVATAS and BEVETEX was established on record.<\/li>\n\n\n\n<li>The evidence of Intas regarding specialised oncological administration remained substantially unrebutted.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"h-on-the-learned-single-judge-s-approach\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"On_the_Learned_Single_Judges_Approach\"><\/span>On the Learned Single Judge&#8217;s Approach<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The court found that the impugned judgement dated March 28, 2026, determined the entire issue of infringement solely on a bare visual and phonetic comparison of the marks undertaken by the judge himself, without evaluating any of the evidence led at trial.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court noted that the learned Single Judge, while correctly setting out the governing legal principles in paragraphs 19 to 29 of the impugned judgement,https:\/\/www.legalserviceindia.com\/Legal-Articles\/delhi-high-court-bevatas-vs-bevetex-pharmaceutical-trademark-infringement-ruling-2026\/ proceeded directly to conclude at paragraph 28 that a likelihood of confusion existed, without adverting to any oral or documentary evidence of the parties.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court held that this approach, at the post-trial stage, was legally unsustainable. A bare comparison of marks by the court can at best constitute a prima facie view appropriate for deciding interim applications; it cannot form the basis of a final decree of permanent injunction after a full trial.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court noted that the impugned judgement effectively imported the statutory presumption under Section 29(3) of the Act without even acknowledging it, despite that presumption being wholly inapplicable on the facts of the case.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court also noted that after the interim injunction was denied and that denial was confirmed right up to the Supreme Court, the learned Single Judge would have needed clear and cogent evidence emerging at trial to form a contra view, but Sun Pharma had produced no new documentary or oral evidence from any relevant member of the public after the dismissal of the interim injunction.<\/p>\n\n\n\n<h3 id=\"h-key-findings-on-the-single-judge-s-approach\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Key_Findings_on_the_Single_Judges_Approach\"><\/span>Key Findings on the Single Judge&#8217;s Approach<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Infringement was determined through visual and phonetic comparison alone.<\/li>\n\n\n\n<li>No oral or documentary evidence presented during trial was evaluated.<\/li>\n\n\n\n<li>The post-trial decision relied on a methodology suitable only for interim proceedings.<\/li>\n\n\n\n<li>Section 29(3) presumption was effectively applied despite being inapplicable.<\/li>\n\n\n\n<li>No fresh evidence was produced after refusal of the interim injunction.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"h-on-the-similarity-of-the-two-drugs\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"On_the_Similarity_of_the_Two_Drugs\"><\/span>On the Similarity of the Two Drugs<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The court, relying on the undisputed comparative table of the two drugs set out in paragraph 9.9 of the impugned judgement itself, found that BEVATAS and BEVETEX were wholly dissimilar drugs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">BEVATAS is a biological rDNA drug containing bevacizumab, a monoclonal antibody, while BEVETEX is a synthetic chemical drug containing paclitaxel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One is prescribed as the first line of treatment, the other only after failure of chemotherapy. Their indications are different, their dosage regimens are different, their infusion durations are different (90 minutes initially for BEVATAS versus 30 minutes for BEVETEX), their reconstitution procedures are different, and their side effect profiles are starkly different.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The only overlap in indication is metastatic breast cancer (mBC), but even that overlap is not real because BEVATAS is given to mBC patients as a first-line treatment, while BEVETEX is given only when those patients have failed to respond to chemotherapy, meaning the same patient would never receive both drugs at the same time or in substitution for each other.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Both parties had admitted that the two drugs were not therapeutic substitutes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The price difference of Rs. 25,990 for 100 mg of BEVATAS versus Rs. 12,500 for 100 mg of BEVETEX was another factor militating against confusion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court held that drugs that are not interchangeable, do not serve the same therapeutic purpose, and are not perceived by oncologists, chemists, or patients as alternatives are dissimilar for all purposes of trademark law.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court held that the mere fact that both drugs fall in the Nice Classification of medicinal and pharmaceutical preparations in Class 5 does not make them similar goods.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court relied on factors (c) and (d) of paragraph 35 of the Supreme Court&#8217;s judgement in Cadila Health Care Ltd v.

Orchid Chemicals &amp; Pharmaceuticals Ltd, ILR (2007) I Delhi 874 (MERONEM\/MEROMER), which held that due emphasis must be given to the uncommon letters in rival pharmaceutical marks once publici juris syllables are set aside.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Considering the distinct suffixes ATAS versus ETEX, the court held the marks were not visually or structurally similar either, noting that the packaging of the two drugs was also completely different in colour scheme, font, layout, and overall visual presentation, with both products prominently displaying their respective active molecules, bevacizumab and paclitaxel, in large font on the packaging itself.<\/p>\n\n\n\n<h3 id=\"h-publici-juris-prefixes-used-in-the-industry\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Publici_Juris_Prefixes_Used_in_the_Industry\"><\/span>Publici Juris Prefixes Used in the Industry<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Company<\/th><th>Trademark<\/th><\/tr><\/thead><tbody><tr><td>Zydus<\/td><td>ZYBEV<\/td><\/tr><tr><td>Reliance Lifesciences<\/td><td>BEVACIREL<\/td><\/tr><tr><td>Hetero Drugs<\/td><td>CIZUMAB<\/td><\/tr><tr><td>Lupin<\/td><td>BEVAZZA<\/td><\/tr><tr><td>Emcure<\/td><td>BEVEREST<\/td><\/tr><tr><td>Abbott<\/td><td>BEVACIZAB<\/td><\/tr><tr><td>Cadila Pharma<\/td><td>BEVARO<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 id=\"h-court-findings-on-trademark-comparison\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Court_Findings_on_Trademark_Comparison\"><\/span>Court Findings on Trademark Comparison<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>BEV and BEVA are publici juris and non-distinctive.<\/li>\n\n\n\n<li>The relevant comparison is between TAS and ETEX.<\/li>\n\n\n\n<li>The suffixes create different visual, structural, and phonetic impressions.<\/li>\n\n\n\n<li>The marks must be evaluated as a whole under the anti-dissection rule.<\/li>\n\n\n\n<li>Packaging, colour schemes, fonts, and presentation are materially different.<\/li>\n\n\n\n<li>Active molecules are prominently displayed on both products.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"h-governing-principles-for-infringement\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Governing_Principles_for_Infringement\"><\/span>Governing Principles for Infringement<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The court synthesised the law from three landmark judgements. In <strong>Cadila Health Care Ltd v. Cadila Pharmaceuticals Ltd (2001) 5 SCC 73<\/strong>, the Supreme Court had identified seven factors for determining deceptive similarity of pharmaceutical marks \u2014 the nature of the marks, the degree of resemblance, the nature of the goods, the similarity in nature, character and performance of the goods, the class of purchasers and their education and degree of care, the mode of purchasing, and any other surrounding circumstances \u2014 emphasising that weightage must be given to each factor depending on the facts of the case.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In <strong>Kaviraj Pandit Durga Dutt Sharma v. Navaratna Pharmaceutical Laboratories, 1964 SCC OnLine SC 14<\/strong>, the Supreme Court held that in an infringement action, if the marks bear close similarity, no further evidence is required, but if they are merely similar (not an imitation), the plaintiff must establish that the mark used by the defendant so nearly resembles the plaintiff&#8217;s registered mark as to be likely to deceive or cause confusion, and that deceptive similarity is essentially a question of fact.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In <strong>Gufic Ltd v. Clinique Laboratories, LLC &amp; Anr., 2010 (43) PTC 788<\/strong>, a coordinate bench of the Delhi High Court had culled out that the test of deceptive similarity in infringement cases is the same as in passing-off actions where marks are not identical, and five principles must be applied, including overall structural and phonetic similarity and whether both marks convey the same idea.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court synthesised these authorities to hold that infringement adjudication in cases of similar (not identical) marks proceeds in two stages \u2014 a threshold comparison of marks by the court itself to assess degree of visual, structural, and phonetic resemblance, and if the marks are not found wholly dissimilar or nearly identical imitations, a second evidence-based stage where the court must assess deceptive similarity and likelihood of confusion on the basis of all the Cadila-2001 factors and the evidence led at trial.<\/p>\n\n\n\n<h3 id=\"h-two-stage-test-for-infringement-analysis\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Two-Stage_Test_for_Infringement_Analysis\"><\/span>Two-Stage Test for Infringement Analysis<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>Stage<\/th><th>Purpose<\/th><th>Assessment Criteria<\/th><\/tr><tr><td>Stage 1<\/td><td>Threshold comparison of marks<\/td><td>Visual, structural, and phonetic resemblance<\/td><\/tr><tr><td>Stage 2<\/td><td>Evidence-based examination<\/td><td>Deceptive similarity, likelihood of confusion, Cadila factors, and trial evidence<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 id=\"h-cadila-factors-for-deceptive-similarity\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Cadila_Factors_for_Deceptive_Similarity\"><\/span>Cadila Factors for Deceptive Similarity<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Nature of the marks.<\/li>\n\n\n\n<li>Degree of resemblance.<\/li>\n\n\n\n<li>Nature of the goods.<\/li>\n\n\n\n<li>Similarity in nature, character and performance of the goods.<\/li>\n\n\n\n<li>Class of purchasers, their education, and degree of care.<\/li>\n\n\n\n<li>Mode of purchasing.<\/li>\n\n\n\n<li>Other surrounding circumstances.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"h-surrounding-circumstances-and-public-interest\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Surrounding_Circumstances_and_Public_Interest\"><\/span>Surrounding Circumstances and Public Interest<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Examining the surrounding circumstances in terms of the Cadila-2001 factors, the court found that since both drugs are Schedule H drugs requiring an oncologist&#8217;s prescription and administered only in oncology clinics by trained nurses under oncologist supervision, there was little scope for casual or uninformed consumer choice at any stage \u2014 prescription, dispensing, or administration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The high price of both drugs (over Rs. 12,500 even for the smaller dose) meant purchasers would exercise heightened caution. The prominent display of the molecule name on the packaging ruled out confusion even for persons with imperfect recollection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court also rejected Sun Pharma&#8217;s belated oral submission before it that drugs could be sold over the counter without a prescription, noting this had not been pleaded and was not proved.<\/p>\n\n\n\n<h3 id=\"h-court-findings-on-public-interest\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Court_Findings_on_Public_Interest\"><\/span>Court Findings on Public Interest<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">On the question of public interest, the court found Sun Pharma&#8217;s claim to be a red herring. The court held that Sun Pharma had no valid cause of action at all \u2014 it suffered no loss of revenue, no damage to goodwill, and its mark&#8217;s distinctiveness was not eroded in any demonstrable way.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court concluded that Sun Pharma pursued the litigation to protect its purely commercial interest in the mark <strong>BEVETEX<\/strong> under the guise of public interest.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The court also noted that after nearly ten years of concurrent use of both marks from 2016 to 2026, not a single instance of actual confusion in the market had been reported or proved.<\/p>\n\n\n\n<h3 id=\"h-key-factors-relied-upon-by-the-court\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Key_Factors_Relied_Upon_by_the_Court\"><\/span>Key Factors Relied Upon by the Court<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Both drugs are Schedule H prescription medicines.<\/li>\n\n\n\n<li>Administration occurs only in oncology clinics.<\/li>\n\n\n\n<li>Drugs are administered by trained nurses under oncologist supervision.<\/li>\n\n\n\n<li>High product cost encourages careful purchasing decisions.<\/li>\n\n\n\n<li>Molecule names are prominently displayed on packaging.<\/li>\n\n\n\n<li>No proven instance of actual confusion over a decade of concurrent use.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"h-case-law-cited-by-sun-pharma\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Case_Law_Cited_by_Sun_Pharma\"><\/span>Case Law Cited by Sun Pharma<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The court carefully distinguished each precedent cited by Sun Pharma.<\/p>\n\n\n\n<h3 id=\"h-distinguished-precedents\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Distinguished_Precedents\"><\/span>Distinguished Precedents<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>Case<\/th><th>Marks Involved<\/th><th>Court&#8217;s Distinction<\/th><\/tr><tr><td>United Biotech Pvt.

Limited v. Speciality Meditech Pvt. Ltd &amp; Anr., 2025:DHC:5039-DB<\/strong>, supported the principle that where marks are an imitation and goods are identical, no further evidence is needed \u2014 but that this principle had no application where, as here, the marks were not an imitation and the goods were dissimilar.<\/p>\n\n\n\n<h2 id=\"h-conclusion-on-infringement-and-likelihood-of-confusion\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Conclusion_on_Infringement_and_Likelihood_of_Confusion\"><\/span>Conclusion on Infringement and Likelihood of Confusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">After analysing the governing principles, surrounding circumstances, public interest considerations, and the precedents cited by both sides, the court concluded that the present dispute did not involve identical marks, imitation, or goods capable of creating a realistic likelihood of confusion. Given the specialised oncology setting, prescription-only nature of the medicines, trained medical supervision, high-value purchases, and the absence of any reported confusion during nearly a decade of concurrent use, the court found no basis to sustain Sun Pharma&#8217;s claim of infringement or deception.<\/p>\n\n\n\n<h2 id=\"h-final-decision-of-the-court\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Final_Decision_of_the_Court\"><\/span>Final Decision of the Court<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The Division Bench allowed the appeal and set aside the impugned judgement dated March 28, 2026.
