The case occupies a foundational place in the law relating to trademark infringement and passing off, particularly because it clearly explains the distinction between these two causes of action.

word <strong>&#8220;Navaratna&#8221;.<\/strong> The dispute required the court to determine whether the registered proprietor of a trademark could prevent another trader from using a deceptively similar mark and whether the standards applicable to infringement and passing off were identical.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The judgement is of immense importance for businesses seeking to protect their brands, intellectual property practitioners advising trademark owners, and courts dealing with trademark disputes. It provides enduring guidance on the scope of statutory trademark rights, deceptive similarity, acquired distinctiveness, and the relationship between infringement actions and passing off actions.<\/p>\n\n\n\n<h3 id=\"h-why-this-judgment-is-important\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_This_Judgment_Is_Important\"><\/span>Why This Judgment Is Important<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Clarifies the distinction between trademark infringement and passing off.<\/li>\n\n\n\n<li>Explains the concept of deceptive similarity.<\/li>\n\n\n\n<li>Discusses acquired distinctiveness through long and continuous use.<\/li>\n\n\n\n<li>Defines the statutory rights of registered trademark proprietors.<\/li>\n\n\n\n<li>Continues to serve as a leading precedent in Indian trademark law.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\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 class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The respondent, Navaratna Pharmaceutical Laboratories, was engaged in the manufacture and sale of medicinal and pharmaceutical products. The business had been established around 1926 and initially operated under the name <strong>\u201cNavaratna Pharmacy&#8221;.<\/strong> In January 1945, the name was changed to <strong>\u201cNavaratna Pharmaceutical Laboratories&#8221;.<\/strong> From its inception, the business used the mark <strong>\u201cNavaratna\u201d<\/strong> in relation to its medicinal products and built substantial goodwill and reputation in the market.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In December 1928, the word <strong>\u201cNavaratna\u201d<\/strong> and the name <strong>\u201cNavaratna Pharmacy\u201d<\/strong> were registered through a declaration of ownership before the Registrar of Assurances at Calcutta. Subsequently, under the Cochin Trade Marks Act, the respondent obtained registration of the mark <strong>\u201cNavaratna\u201d<\/strong> in respect of medicinal preparations on <strong>31 January 1947<\/strong> and also secured registration of <strong>\u201cNavaratna Pharmaceutical Laboratories\u201d<\/strong> on <strong>17 February 1948<\/strong>. The respondent thereafter expanded its business and continuously marketed its products under these marks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The appellant, Kaviraj Pandit Durga Dutt Sharma, was carrying on business at Jullundur in Punjab and manufactured Ayurvedic pharmaceutical products under the name <strong>\u201cNavaratna Kalpa Pharmacy&#8221;.<\/strong> He sold his products under the mark <strong>\u201cNavaratna Kalpa\u201d<\/strong> and applied for registration of that mark in October 1946. When the application was advertised, the respondent opposed the registration. The opposition succeeded, and the appellant\u2019s application was refused.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Following the refusal of registration, the appellant initiated proceedings seeking removal of the respondent\u2019s trademarks from the register. Since a civil suit had already been instituted by the respondent, seeking a permanent injunction against the appellant, the Registrar directed the appellant to approach the High Court for rectification of the register. Consequently, the appellant filed a rectification petition before the High Court.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Simultaneously, the respondent instituted a civil suit seeking a permanent injunction restraining the appellant from advertising, selling, or offering medicinal products under any mark containing the word <strong>&#8220;Navaratna&#8221;.<\/strong> The respondent asserted infringement of its registered trademarks and also alleged passing off. The trial court granted relief in favour of the respondent regarding infringement, though issues relating to passing off were separately considered. The High Court affirmed the respondent\u2019s position. The appellant thereafter approached the Supreme Court.<\/p>\n\n\n\n<h3 id=\"h-timeline-of-key-events\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Timeline_Of_Key_Events\"><\/span>Timeline Of Key Events<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>Year\/Date<\/th><th>Event<\/th><\/tr><\/thead><tbody><tr><td>1926<\/td><td>The respondent commenced business as &#8220;Navaratna Pharmacy&#8221;.<\/td><\/tr><tr><td>December 1928<\/td><td>&#8220;Navaratna&#8221; and &#8220;Navaratna Pharmacy&#8221; were registered through a declaration of ownership before the Registrar of Assurances at Calcutta.<\/td><\/tr><tr><td>January 1945<\/td><td>The business name changed to &#8220;Navaratna Pharmaceutical Laboratories&#8221;.<\/td><\/tr><tr><td>October 1946<\/td><td>The appellant applied to register the mark &#8220;Navaratna Kalpa&#8221;.<\/td><\/tr><tr><td>31 January 1947<\/td><td>The respondent obtained registration of the trademark &#8220;Navaratna&#8221;.<\/td><\/tr><tr><td>17 February 1948<\/td><td>Registration granted for &#8220;Navaratna Pharmaceutical Laboratories&#8221;.<\/td><\/tr><tr><td>Subsequent Period<\/td><td>Opposition succeeded, rectification proceedings commenced, and the respondent filed a suit for infringement and passing off.<\/td><\/tr><tr><td>Thereafter<\/td><td>The matter reached the Supreme Court of India.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 id=\"h-key-parties\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Key_Parties\"><\/span>Key Parties<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><\/tr><\/thead><tbody><tr><td>Navaratna Pharmaceutical Laboratories<\/td><td>Respondent and registered proprietor of the &#8220;Navaratna&#8221; trademarks.<\/td><\/tr><tr><td>Kaviraj Pandit Durga Dutt Sharma<\/td><td>Appellant is using the marks &#8220;Navaratna Kalpa&#8221; and &#8220;Navaratna Kalpa Pharmacy&#8221;.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 id=\"h-dispute-before-the-court\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Dispute_Before_the_Court\"><\/span>Dispute Before the Court<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The principal issues before the Supreme Court were whether the respondent\u2019s trademarks had been validly registered and whether they had acquired distinctiveness through long and continuous use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Court was also required to determine whether the appellant\u2019s use of the mark <strong>\u201cNavaratna Kalpa\u201d<\/strong> and the trading style <strong>\u201cNavaratna Kalpa Pharmacy\u201d<\/strong> amounted to infringement of the respondent\u2019s registered trademarks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another important issue concerned the relationship between trademark infringement and passing off. The appellant argued that the packaging, appearance, colour scheme, and presentation of the parties\u2019 products were different, and therefore there was no likelihood of confusion. According to the appellant, the respondent could not claim exclusive rights over the word <strong>&#8220;Navaratna&#8221;,<\/strong> which was allegedly common to the trade.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The respondent, on the other hand, contended that through decades of use the mark <strong>\u201cNavaratna\u201d<\/strong> had become exclusively associated with its medicinal products and that the appellant\u2019s adoption of a deceptively similar mark infringed its statutory rights as a registered proprietor.<\/p>\n\n\n\n<h3 id=\"h-principal-issues-before-the-supreme-court\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Principal_Issues_Before_the_Supreme_Court\"><\/span>Principal Issues Before the Supreme Court<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Whether the respondent&#8217;s trademarks had been validly registered.<\/li>\n\n\n\n<li>Whether the mark <strong>\u201cNavaratna\u201d<\/strong> had acquired distinctiveness through long and continuous use.<\/li>\n\n\n\n<li>Whether the appellant&#8217;s use of <strong>\u201cNavaratna Kalpa\u201d<\/strong> constituted trademark infringement.<\/li>\n\n\n\n<li>Whether the respondent could claim exclusive rights over the word <strong>&#8220;Navaratna&#8221;.<\/strong><\/li>\n\n\n\n<li>Whether the legal tests for infringement and passing off were identical.<\/li>\n<\/ul>\n\n\n\n<h3 id=\"h-arguments-of-the-parties\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Arguments_of_the_Parties\"><\/span>Arguments of the Parties<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>Appellant<\/th><th>Respondent<\/th><\/tr><\/thead><tbody><tr><td>The packaging, appearance, colour scheme and presentation were different.<\/td><td>The mark &#8220;Navaratna&#8221; had acquired goodwill and distinctiveness through decades of continuous use.<\/td><\/tr><tr><td>No likelihood of consumer confusion existed.<\/td><td>The appellant adopted a deceptively similar mark.<\/td><\/tr><tr><td>The word &#8220;Navaratna&#8221; was common to the trade.<\/td><td>The respondent possessed statutory rights as the registered proprietor.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\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-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The Supreme Court began by examining the validity of the respondent\u2019s trademark registrations. The Court noted that the respondent had been using the mark <strong>\u201cNavaratna\u201d<\/strong> continuously since the 1920s and had acquired substantial goodwill and reputation. The evidence established that the mark had become identified in the market with the respondent\u2019s pharmaceutical products. The Court therefore accepted the concurrent findings of the lower courts that the mark had acquired distinctiveness through long and extensive use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Court rejected the challenge to the validity of registration. It held that a mark which has acquired factual distinctiveness through long use is entitled to protection even if the mark originally consisted of words that may not have been inherently distinctive. The Court observed that actual and continuous market association can transform a mark into a distinctive identifier of commercial origin.<\/p>\n\n\n\n<h3 id=\"h-acquired-distinctiveness-through-long-use\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Acquired_Distinctiveness_Through_Long_Use\"><\/span>Acquired Distinctiveness Through Long Use<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The court recognised that continuous commercial use over several decades had enabled the mark <strong>\u201cNavaratna\u201d<\/strong> to acquire factual distinctiveness. Consequently, the mark became legally protectable despite any alleged lack of inherent distinctiveness at its inception.<\/p>\n\n\n\n<h3 id=\"h-deceptive-similarity-test\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Deceptive_Similarity_Test\"><\/span>Deceptive Similarity Test<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A significant portion of the judgement dealt with deceptive similarity. The Court agreed with the findings of the courts below that the expressions <strong>\u201cNavaratna Pharmacy&#8221;, \u201cNavaratna Kalpa&#8221;,<\/strong> and <strong>\u201cNavaratna Pharmaceutical Laboratories\u201d<\/strong> bore sufficient resemblance to create a likelihood of deception or confusion. The test was not whether the marks were identical but whether the resemblance was such that an ordinary purchaser would be likely to associate one trader\u2019s goods with those of another.<\/p>\n\n\n\n<h3 id=\"h-difference-between-infringement-and-passing-off\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Difference_Between_Infringement_And_Passing_Off\"><\/span>Difference Between Infringement And Passing Off<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The most enduring contribution of the judgement lies in its detailed explanation of the distinction between infringement and passing off. The Court observed that an action for passing off is a common law remedy based on the principle that one trader should not misrepresent his goods as those of another. Passing off is essentially an action founded on deceit and protection of goodwill. By contrast, an action for infringement is a statutory remedy available to the registered proprietor of a trademark.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Court explained that in an infringement action the focus is on the unauthorised use of a mark that is identical or deceptively similar to the registered trademark. Once the essential features of the registered mark are copied, infringement may be established even if there are differences in packaging, labels, colour schemes, or get-up. In contrast, in a passing off action, the overall presentation of the goods becomes highly relevant because the inquiry is whether consumers are likely to be deceived into believing that one trader\u2019s goods originate from another.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Court held that the appellant\u2019s argument based on differences in packaging and presentation was relevant primarily to the passing off claim and not to the infringement claim. Where the essential features of a registered trademark have been adopted by another trader, infringement can be established notwithstanding differences in external appearance.<\/p>\n\n\n\n<h3 id=\"h-statutory-protection-under-the-trade-marks-act-1940\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Statutory_Protection_Under_the_Trade_Marks_Act_1940\"><\/span>Statutory Protection Under the Trade Marks Act, 1940<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">While deciding the matter, the Court discussed the provisions of the Trade Marks Act, 1940, relating to registration, distinctiveness, infringement, and rectification. It analysed the statutory protection granted to registered proprietors and emphasised that registration confers valuable proprietary rights which cannot be lightly undermined.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Court ultimately found no merit in the appellant\u2019s challenge to the respondent\u2019s registration and upheld the respondent\u2019s right to protect its trademark against infringement.<\/p>\n\n\n\n<h3 id=\"h-key-principles-laid-down-by-the-court\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Key_Principles_Laid_Down_by_the_Court\"><\/span>Key Principles Laid Down by the Court<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Long and continuous use can confer acquired distinctiveness.<\/li>\n\n\n\n<li>Registration grants valuable statutory proprietary rights.<\/li>\n\n\n\n<li>The test for deceptive similarity depends upon the perception of an ordinary purchaser.<\/li>\n\n\n\n<li>Copying the essential features of a registered mark may constitute infringement.<\/li>\n\n\n\n<li>Differences in packaging or get-up generally do not defeat an infringement claim.<\/li>\n\n\n\n<li>Passing off focuses on misrepresentation and consumer deception.<\/li>\n\n\n\n<li>Trademark infringement and passing off are distinct causes of action with different legal requirements.<\/li>\n<\/ul>\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 Supreme Court dismissed the appellant\u2019s challenge and upheld the respondent\u2019s trademark rights. The Court affirmed the validity of the respondent\u2019s registrations and held that the respondent was entitled to protection against infringement of its registered trademarks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Court concluded that the appellant\u2019s use of marks containing the word <strong>\u201cNavaratna\u201d<\/strong> in the manner adopted by him infringed the respondent\u2019s registered trademark rights. The relief granted in favour of the respondent was therefore sustained. The appeals were accordingly dismissed.<\/p>\n\n\n\n<h3 id=\"h-supreme-court-holding\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Supreme_Court_Holding\"><\/span>Supreme Court Holding<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The respondent&#8217;s trademark registrations were valid.<\/li>\n\n\n\n<li>The mark <strong>&#8220;Navaratna&#8221;<\/strong> had acquired distinctiveness through long and continuous use.<\/li>\n\n\n\n<li>The appellant&#8217;s use of <strong>&#8220;Navaratna Kalpa&#8221;<\/strong> infringed the respondent&#8217;s registered trademarks.<\/li>\n\n\n\n<li>The challenge to the respondent&#8217;s registrations failed.<\/li>\n\n\n\n<li>The appeals were dismissed.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"h-point-of-law-settled\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Point_Of_Law_Settled\"><\/span>Point Of Law Settled<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The judgement authoritatively establishes the distinction between an action for trademark infringement and an action for passing off.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Court clarified that infringement is a statutory remedy available to the proprietor of a registered trademark. In such cases, if the essential features of the registered mark have been copied, infringement may be established even if there are differences in packaging, get-up, colour scheme, or presentation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In contrast, passing off is a common law remedy based on misrepresentation and protection of goodwill. In passing off actions, the overall appearance of the goods and the likelihood of consumer deception assume greater significance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The judgement also reaffirms that long and continuous use of a mark can result in acquired distinctiveness, thereby entitling the mark to legal protection. This decision continues to serve as a foundational precedent in Indian trademark law and remains one of the most frequently cited authorities on deceptive similarity, trademark infringement, and passing off.<\/p>\n\n\n\n<h3 id=\"h-legal-principles-established\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Legal_Principles_Established\"><\/span>Legal Principles Established<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>Principle<\/th><th>Legal Position Established<\/th><\/tr><\/thead><tbody><tr><td>Trademark Infringement<\/td><td>A statutory remedy available to the registered proprietor of a trademark.<\/td><\/tr><tr><td>Passing Off<\/td><td>A common law remedy based on misrepresentation and protection of goodwill.<\/td><\/tr><tr><td>Essential Features Test<\/td><td>Copying the essential features of a registered trademark may constitute infringement even where differences exist in packaging or get-up.<\/td><\/tr><tr><td>Acquired Distinctiveness<\/td><td>Long and continuous use can transform a mark into a distinctive identifier entitled to legal protection.<\/td><\/tr><tr><td>Deceptive Similarity<\/td><td>The relevant test is the likelihood of deception or confusion from the perspective of an ordinary purchaser.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"h-key-takeaways\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Key_Takeaways\"><\/span>Key Takeaways<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Trademark infringement and passing off are distinct legal causes of action.<\/li>\n\n\n\n<li>Registration confers valuable statutory proprietary rights.<\/li>\n\n\n\n<li>Long-standing commercial use may establish acquired distinctiveness.<\/li>\n\n\n\n<li>The essential features of a trademark receive legal protection.<\/li>\n\n\n\n<li>Minor differences in labels, packaging or colour schemes generally do not avoid infringement.<\/li>\n\n\n\n<li>The judgement remains a leading authority on deceptive similarity in Indian trademark law.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"h-case-details\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Case_Details\"><\/span>Case Details<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>Title of the Case<\/th><td><strong>Kaviraj Pandit Durga Dutt Sharma Vs Navaratna Pharmaceutical Laboratories<\/strong><\/td><\/tr><tr><th>Date of Judgment\/Order<\/th><td>20 October 1964<\/td><\/tr><tr><th>Case Number<\/th><td>Civil Appeals Nos. 522 and 523 of 1962<\/td><\/tr><tr><th>Citations<\/th><td>AIR 1965 SC 980; (1965) 1 SCR 737<\/td><\/tr><tr><th>Name of Court<\/th><td>Supreme Court of India<\/td><\/tr><tr><th>Name of Honourable Judges<\/th><td>Chief Justice P.B.
