It also underscores the high threshold required to challenge a registered trademark at the interim stage.<\/p><div id=\"ez-toc-container\" class=\"ez-toc-v2_0_82_2 counter-hierarchy ez-toc-counter

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Sun Pharma Laboratories Limited, a major pharmaceutical company, claimed rights over the trademark \u201cOCTRIDE\u201d used for injections containing octreotide acetate, a drug prescribed for serious conditions like acromegaly and certain tumours. The company traced its rights back to the late 1990s through predecessors and asserted substantial sales and reputation across India and globally.<\/p>\n\n\n\n<p>United Biotech Private Limited, another pharmaceutical manufacturer with exports to several countries, had been selling the same drug under the mark \u201cOTIDE\u201d for many years. Both marks are derived from the International Non-Proprietary Name (INN) of the active ingredient &#8220;Octreotide&#8221;. Sun Pharma filed a commercial intellectual property suit seeking an injunction against United Biotech for trademark infringement and passing off. An ex-parte ad-interim injunction was initially granted in July 2025, which United Biotech later challenged by filing an application to vacate it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"key-parties-in-the-case\"><span class=\"ez-toc-section\" id=\"Key_Parties_In_The_Case\"><\/span>Key Parties In The Case<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>Party<\/th><th>Role<\/th><th>Trademark Used<\/th><\/tr><\/thead><tbody><tr><td>Sun Pharma Laboratories Limited<\/td><td>Plaintiff<\/td><td>\u201cOCTRIDE\u201d<\/td><\/tr><tr><td>United Biotech Private Limited<\/td><td>Defendant<\/td><td>\u201cOTIDE\u201d<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"important-legal-issues\"><span class=\"ez-toc-section\" id=\"Important_Legal_Issues\"><\/span>Important Legal Issues<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Trademark infringement in the pharmaceutical sector<\/li>\n\n\n\n<li>Protection of goodwill and reputation<\/li>\n\n\n\n<li>Use of marks derived from generic drug names<\/li>\n\n\n\n<li>Passing off claims<\/li>\n\n\n\n<li>Interim injunction standards under trademark law<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"importance-of-the-ruling\"><span class=\"ez-toc-section\" id=\"Importance_Of_The_Ruling\"><\/span>Importance Of The Ruling<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The ruling is significant because it demonstrates how courts approach disputes involving pharmaceutical trademarks that are partially derived from generic drug names. The judgment also reflects judicial caution in balancing public interest, established market presence, and trademark exclusivity in the healthcare industry.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"dispute-over-octride-and-otide-trademarks\"><span class=\"ez-toc-section\" id=\"Dispute_Over_%E2%80%9COCTRIDE%E2%80%9D_and_%E2%80%9COTIDE%E2%80%9D_Trademarks\"><\/span>Dispute Over \u201cOCTRIDE\u201d and \u201cOTIDE\u201d Trademarks<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The core dispute centred on whether Sun Pharma could stop United Biotech from using &#8220;OTIDE&#8221;. Sun Pharma argued phonetic and visual similarity between \u201cOCTRIDE\u201d and \u201cOTIDE\u201d would cause confusion among doctors, pharmacists, and patients. It claimed prior adoption, registration, and extensive goodwill.<\/p>\n\n\n\n<p>United Biotech countered that it had honestly adopted and used its mark since 1999 and obtained registration, and both marks had co-existed in the market for years without actual confusion. The defendant also raised issues of delay by Sun Pharma.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"reasoning-and-analysis-of-the-judge\"><span class=\"ez-toc-section\" id=\"Reasoning_and_Analysis_of_the_Judge\"><\/span>Reasoning and Analysis of the Judge<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The court carefully examined the rival marks, their registrations, market use, and applicable legal principles. The judge noted that both parties hold trademark registrations, creating a situation where neither can easily claim exclusive rights against the other without strong grounds.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"court-findings-on-infringement\"><span class=\"ez-toc-section\" id=\"Court_Findings_on_Infringement\"><\/span>Court Findings on Infringement<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>On infringement, the court held that Sun Pharma failed to demonstrate that United Biotech\u2019s registration was ex facie illegal or fraudulent. The judge referred to the high threshold laid down by the Full Bench of the Bombay High Court in <em>Lupin Limited vs Johnson and Johnson MANU\/MH\/3536\/2015<\/em>.<\/p>\n\n\n\n<p>Since both marks derive from the same generic molecule name, the registration could not be treated as shocking the conscience of the court.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"passing-off-and-confusion-test\"><span class=\"ez-toc-section\" id=\"Passing_Off_and_Confusion_Test\"><\/span>Passing Off and Confusion Test<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>For passing off, the court applied the classic trinity test of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Goodwill<\/li>\n\n\n\n<li>Misrepresentation<\/li>\n\n\n\n<li>Damage<\/li>\n<\/ul>\n\n\n\n<p>While acknowledging Sun Pharma\u2019s sales and reputation, the judge found that United Biotech had been using its mark subsequent to Plaintiff. The court emphasised that in pharmaceutical cases, the threshold for confusion is lower due to public health concerns.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"important-precedents-discussed\"><span class=\"ez-toc-section\" id=\"Important_Precedents_Discussed\"><\/span>Important Precedents Discussed<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The judge discussed several important precedents, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cadila Health Care Ltd vs Cadila Pharmaceuticals Ltd<\/strong> \u2013 on heightened scrutiny in pharma trademarks.<\/li>\n\n\n\n<li><strong>Wander Ltd vs Antox India Pvt.
