The patent application was filed on 17 October 2006 and granted on 28 December 2010 without opposition. The invention aimed to facilitate the tracking and recovery of lost or stolen mobile devices through embedded non-erasable security elements.<\/p>\n<p>The suit patent, later assigned to plaintiff No. 1, a company recognized under the Indian startup and MSME frameworks, claims features including a flash memory capable of auto-reinstalling data, and a silent auto-answer mode. The plaintiffs claim that between 2015 and 2019, subscriptions to the patented system were sold both online and offline. In January 2023, the plaintiffs discovered that Xiaomi\u2019s devices were using a \u201cFind Device\u201d feature that they believed infringed their patent.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Procedural_Background\"><\/span>Procedural Background<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The plaintiffs filed the suit in May 2023 seeking permanent injunction, damages, and interim relief. Initial summons were issued on 29 May 2023. Mediation was attempted but failed. Subsequently, an application under Order XXXIX Rules 1 and 2 CPC was filed seeking interim injunction and directions for royalty deposit. Xiaomi filed its written statement and a counterclaim for revocation of the suit patent on 14 August 2023, asserting lack of novelty and inventive step.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Legal_Issue\"><\/span>Legal Issue<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The primary legal issues were:<\/p>\n<ul>\n<li>Whether Xiaomi\u2019s \u201cFind Device\u201d feature infringed the suit patent.<\/li>\n<li>Whether all essential features of the independent claim were present in Xiaomi\u2019s devices.<\/li>\n<li>Whether the plaintiffs were entitled to interim injunction despite alleged non-working of the patent and delay in approaching the court.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Discussion_on_Judgments\"><\/span>Discussion on Judgments<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In <em>Biswanath Prasad Radhey Shyam v. Hindustan Metal Industries<\/em>, (1979) 2 SCC 511, the Supreme Court underscored that in patent infringement suits, the complete specification must be closely analyzed to construe the claims.<\/p>\n<p>The plaintiffs cited <em>Sotefin SA v. Indraprastha Cancer Society &amp; Research Center<\/em>, 2022 SCC OnLine Del 516, to argue for a holistic interpretation of claims based on the invention\u2019s pith and marrow, not a literal claim-by-claim comparison. However, the court held this case distinguishable since essential features of the claim were absent in Xiaomi\u2019s devices.<\/p>\n<p>In <em>Crystal Crop Protection Ltd. v. Safex Chemicals India Ltd.<\/em>, 2025 SCC OnLine Del 2981, the Delhi High Court reaffirmed that essential features of a patent are those that address problems identified in prior art. This principle was relied upon to assess whether Xiaomi\u2019s devices had the essential features of the suit patent.<\/p>\n<p>The court also referred to <em>Guala Closures v. AGI Greenpac Ltd.<\/em>, 2024 SCC OnLine Del 3510, to identify that the portion of a claim introduced with \u201ccharacterized in that\u201d typically includes the novelty.<\/p>\n<p>Regarding dependent claims, the court applied <em>Teledyne McCormick Selph v. United States<\/em>, MANU\/USFD\/0071\/1977, which held that if independent claims are not infringed, dependent claims cannot be infringed either. This was reinforced by <em>Wahpeton Canvas Co. v. Frontier, Inc.<\/em>, MANU\/USFD\/0128\/1989, and other international judgments.<\/p>\n<p>To assess the effect of non-working of patents on interim relief, the court relied on <em>Franz Xaver Huemer v. New Yash Engineers<\/em>, 1996 SCC OnLine Del 243, where a Division Bench held that patentees who have not worked their invention in India are not entitled to equitable interim relief.<\/p>\n<h3><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><\/h3>\n<p>The Court methodically analyzed the patent claims and Xiaomi\u2019s \u201cFind Device\u201d feature. The Court began by reviewing the suit patent\u2019s specification and identified that its essential features included a flash memory with data reinstallation, a ROM with non-erasable message center number, and a silent auto-answer mode triggered remotely.<\/p>\n<p>Xiaomi\u2019s \u201cFind Device\u201d could remotely lock, erase data, or play sound, but lacked the ability to silently auto-answer incoming calls or reinstall deleted data. It was also vulnerable to factory resets, whereas the patented invention specifically guarded against such resets through reinstallation from non-erasable memory.<\/p>\n<p>The court found the plaintiffs\u2019 claim mapping deficient as it failed to demonstrate that Xiaomi\u2019s feature included these essential components. Since independent claim 1 was not infringed, dependent claims could not be relied upon either.<\/p>\n<p>The judge also noted that Forms 27 filed by the plaintiffs with the Patent Office indicated minimal use of the patent in India, and only for a limited time in FY 2019\u201320. The court held that non-working of the patent and absence of evidence of substantial commercial exploitation weighed against the grant of an injunction.<\/p>\n<p>Additionally, the court found the plaintiffs\u2019 explanation of discovering the infringement in 2023 unconvincing, noting that Xiaomi had been selling its phones with the \u201cFind Device\u201d feature since 2014. This unexplained delay further weakened their claim for equitable relief.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Final_Decision\"><\/span>Final Decision<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The court held that the plaintiffs failed to establish a prima facie case of patent infringement. Since the essential features of the patent were not found in Xiaomi\u2019s devices, interim injunction could not be granted. The balance of convenience and irreparable injury also favored the defendant. The court dismissed the applications for interim injunction but directed Xiaomi to maintain accounts of the impugned devices and file half-yearly statements. Observations made were expressly limited to the interim stage and not to prejudice final adjudication.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Law_Settled_in_This_Case\"><\/span>Law Settled in This Case<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>This case reinforces the principle that in patent infringement analysis, the essential features of the independent claim must be shown to be present in the impugned product. A patentee cannot succeed merely by showing partial overlap with dependent claims. Non-working of the patent in India and inordinate delay in asserting patent rights can justify denial of equitable interim relief. Claim mapping must be comprehensive and must demonstrate the presence of all inventive elements, especially those that overcome limitations in prior art. The court also reiterated that a \u201ccharacterized in that\u201d clause in a claim often defines the novelty and must be carefully considered.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Case_Details\"><\/span>Case Details<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li><strong>Case Title:<\/strong> Conqueror Innovations Pvt.
