However, not every invention qualifies for a patent. The Indian Patents Act, 1970, delineates strict criteria that an invention must meet to be patentable. This assignment aims to provide an in-depth understanding of the patentability criteria under Indian Patent Law, highlighting the statutory requirements, key legal principles, and judicial interpretations that determine whether an invention can be granted a patent in India.<\/p><div id=\"ez-toc-container\" class=\"ez-toc-v2_0_82_2 counter-hierarchy ez-toc-counter ez-toc-grey

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The Indian patent system is governed predominantly by the Patents Act, 1970, along with the Patents Rules, 2003. The act has been amended over time to meet international standards, including those mandated by the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS). The Act defines an invention under Section 2(1)(j) and sets out what inventions are eligible for patents, as well as exclusions under Sections 3 and 4. These form the foundation for understanding patentability in India.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"core-patentability-criteria\"><span class=\"ez-toc-section\" id=\"Core_Patentability_Criteria\"><\/span>Core Patentability Criteria<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>For an invention to be granted a patent in India, it must meet the three fundamental criteria of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Novelty (Newness)<\/li>\n\n\n\n<li>Inventive Step (Non-Obviousness)<\/li>\n\n\n\n<li>Industrial Applicability (Utility)<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"novelty-newness\"><span class=\"ez-toc-section\" id=\"Novelty_Newness\"><\/span>Novelty (Newness)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Novelty means that the invention must be new and not disclosed to the public anywhere in the world before the date of filing.
