Dexo Laboratories<\/em>, confining review to arbitrariness, perversity, or contravention of settled principles rather than reappreciating evidence. It recapitulated patent infringement tests from <em>F. Hoffmann-La Roche Ltd. v. Cipla Ltd.<\/em>, emphasizing two-stage analysis: claim construction as a legal exercise, reading specifications holistically to ascertain scope without extraneous limitations, followed by comparison with the accused product.<\/p>\n\n\n\n<p>Claims define monopoly, construed purposively from the skilled person&#8217;s perspective, ensuring consistency for validity and infringement. The court affirmed the doctrine of equivalents from <em>FMC Corporation v. Vovantis Crop Protection Pvt. Ltd.<\/em>, preventing evasion through minor variations, applying &#8220;function-way-result&#8221; for products but &#8220;essential element test&#8221; for processes, comparing elements, steps, and interactions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"application-of-doctrine-of-equivalents\"><span class=\"ez-toc-section\" id=\"Application_of_Doctrine_of_Equivalents\"><\/span>Application of Doctrine of Equivalents<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Applying this, the bench found the single judge correctly identified seven inventive steps from Claims 1 and 39, with Canva admitting three, and properly mapped the disputed four:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Layered presentation retaining interactivity<\/li>\n\n\n\n<li>Modifiable layers without re-recording<\/li>\n\n\n\n<li>Configuration interface for editing stored content<\/li>\n\n\n\n<li>Rendering CTAs during playback<\/li>\n<\/ul>\n\n\n\n<p>It rejected Canva&#8217;s arguments of product-to-product comparison, noting the judgment&#8217;s claim-centric focus, and upheld equivalence application, deeming absences like movability or sandwiched layers inessential variations.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"validity-and-prior-art\"><span class=\"ez-toc-section\" id=\"Validity_and_Prior_Art\"><\/span>Validity and Prior Art<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>On validity, the bench dismissed anticipation pleas, finding the single judge compared prior art with claims, implicitly treating layering and configurability as inventive over non-merged, non-interactive systems.

It affirms appellate restraint in interlocutory appeals, interfering only for perversity or principle errors, and validates securing foreign defendants via deposits based on usage data when no local assets exist, balancing irreparable harm to patentees against minimal prejudice to infringers with alternative revenues.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"case-details\"><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>Case Title<\/th><td>Canva Pty Ltd &amp; Ors.
