disclosed the manner in which the invention was to operate and be performed.<\/p>\n\n\n\n<p>The case is significant because it clarifies that merely identifying an inventive concept is not enough for the grant of a patent. A patent applicant must also fully explain the working methodology of the invention so that a Person Skilled In The Art (PSITA) can practically implement the invention without conducting further research or inventing additional mechanisms.<\/p>\n\n\n\n<p>The judgement also discusses the distinction between inventive step and enablement and explains the legal requirements under Sections 10(4)(a) and 10(5) of the Patents Act, 1970.<\/p>\n\n\n\n<p>The Court ultimately dismissed the appeal and upheld rejection of the patent application on the ground that the complete specification lacked sufficient disclosure regarding transmission, processing, authentication, storage, and communication mechanisms involved in the invention.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"case-overview\"><span class=\"ez-toc-section\" id=\"Case_Overview\"><\/span>Case Overview<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Particulars<\/th><th>Details<\/th><\/tr><\/thead><tbody><tr><td>Case Title<\/td><td>Arti Srivastava vs. The Assistant Controller of Patents<\/td><\/tr><tr><td>Date of Order<\/td><td>11 May 2026<\/td><\/tr><tr><td>Case Number<\/td><td>C.A.

Patent Application No. 1774\/DEL\/2006 on 03.08.2006 for an invention titled <strong>\u201cMethod and System for Detecting Counterfeit Products&#8221;.<\/strong><\/p>\n\n\n\n<p>The invention related to a system intended to help consumers verify whether a product was genuine or counterfeit.<\/p>\n\n\n\n<p>The application proposed the use of labels containing two alphanumeric codes affixed to products:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>One code was visible.<\/li>\n\n\n\n<li>The second code was hidden beneath a scratchable coating.<\/li>\n<\/ul>\n\n\n\n<p>The invention contemplated that a consumer would transmit both codes to a data centre through communication methods such as the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Telephone<\/li>\n\n\n\n<li>SMS<\/li>\n\n\n\n<li>Fax<\/li>\n\n\n\n<li>Internet<\/li>\n\n\n\n<li>Email<\/li>\n<\/ul>\n\n\n\n<p>The data centre would compare the received codes with stored records and return a message indicating whether the product was genuine.<\/p>\n\n\n\n<p>The system also proposed maintaining records of repeated verification attempts in order to detect possible misuse or counterfeit activities.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"patent-prosecution-timeline\"><span class=\"ez-toc-section\"

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The central dispute before the Court revolved around whether the invention disclosed in the complete specification met the legal requirements under Section 10(4)(a) of the Patents Act.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"arguments-by-the-appellant\"><span class=\"ez-toc-section\" id=\"Arguments_By_The_Appellant\"><\/span>Arguments By The Appellant<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The appellant argued that the inventive feature of the invention lay in the simultaneous use of two codes on the product packaging:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>One visible code<\/li>\n\n\n\n<li>One hidden under a scratchable layer<\/li>\n<\/ul>\n\n\n\n<p>According to the appellant:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>None of the cited prior art documents disclosed such a mechanism.<\/li>\n\n\n\n<li>The complete specification, flowcharts, and diagrams adequately explained the invention.<\/li>\n\n\n\n<li>Further technical details regarding transmission and processing were obvious to a PSITA.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"arguments-by-the-respondent\"><span class=\"ez-toc-section\" id=\"Arguments_By_The_Respondent\"><\/span>Arguments By The Respondent<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The respondent, namely the assistant controller of patents, argued that the patent application did not sufficiently disclose how the claimed system actually functioned.<\/p>\n\n\n\n<p>According to the respondent, the specification failed to explain:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>How the codes would be digitally processed<\/li>\n\n\n\n<li>How authentication would occur<\/li>\n\n\n\n<li>How data would be converted and transmitted<\/li>\n\n\n\n<li>How information would be stored<\/li>\n\n\n\n<li>How results would be communicated back to the user<\/li>\n<\/ul>\n\n\n\n<p>The respondent further argued that essential technical details regarding<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>System architecture<\/li>\n\n\n\n<li>Workflow<\/li>\n\n\n\n<li>Verification mechanisms<\/li>\n\n\n\n<li>Processing logic<\/li>\n<\/ul>\n\n\n\n<p>were entirely absent from the specification.<\/p>\n\n\n\n<p>Interestingly, during the hearing, the respondent did not continue to press the objection regarding inventive step under Section 2(1)(ja). Instead, the focus shifted entirely to insufficiency of disclosure under Section 10(4)(a).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"reasoning-and-analysis-of-the-court\"><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>The Court first analysed the nature of the invention. The invention related to counterfeit detection by using visible and hidden identification codes on product labels.<\/p>\n\n\n\n<p>The court noted that the system was intended to allow ordinary consumers to authenticate products without specialised tools.<\/p>\n\n\n\n<p>The Court carefully reviewed the complete specification and the figures provided by the appellant.<\/p>\n\n\n\n<p>It observed that the invention described a process in which a user transmits visible and hidden codes to a data centre, which thereafter verifies authenticity and communicates the result back to the user.<\/p>\n\n\n\n<p>However, the Court found that the specification merely described the broad objective and not the detailed operational mechanism.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"key-deficiencies-identified-by-the-court\"><span class=\"ez-toc-section\" id=\"Key_Deficiencies_Identified_By_The_Court\"><\/span>Key Deficiencies Identified By The Court<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The Court noted that the specification did not adequately explain how the transmission and processing of codes would actually occur.<\/p>\n\n\n\n<p>There was no detailed disclosure regarding:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Digital conversion mechanisms<\/li>\n\n\n\n<li>Verification logic<\/li>\n\n\n\n<li>Authentication protocols<\/li>\n\n\n\n<li>Data handling systems<\/li>\n\n\n\n<li>Storage mechanisms<\/li>\n\n\n\n<li>Communication architecture<\/li>\n<\/ul>\n\n\n\n<p>According to the Court, these were essential aspects of the invention and could not be left entirely to the imagination or further research by a PSITA.<\/p>\n\n\n\n<p>The court specifically observed that the specification lacked sufficient details regarding the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The manner in which the data centre would process the incoming codes<\/li>\n\n\n\n<li>The mechanism through which digital information would be authenticated<\/li>\n\n\n\n<li>The protocols and architecture for communication between user and data centre<\/li>\n\n\n\n<li>The storage and reuse of processed information<\/li>\n\n\n\n<li>The safeguards against repeated misuse of already verified codes<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"interpretation-of-section-10-4-a\"><span class=\"ez-toc-section\" id=\"Interpretation_Of_Section_104a\"><\/span>Interpretation Of Section 10(4)(a)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The court emphasised that under Section 10(4)(a), a complete specification must:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>&#8220;Fully and particularly describe the invention and its operation or use and the method by which it is to be performed.\u201d<\/p>\n<\/blockquote>\n\n\n\n<p>The Court interpreted this provision to mean that the invention must be practically reproducible by a PSITA without requiring further inventive effort.<\/p>\n\n\n\n<p>The Court further held that although the invention identified communication modes such as SMS, internet, and email, it did not disclose the actual implementation mechanism.<\/p>\n\n\n\n<p>Merely mentioning communication mediums was not enough to satisfy the enablement requirement.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"best-method-requirement\"><span class=\"ez-toc-section\" id=\"Best_Method_Requirement\"><\/span>Best Method Requirement<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The Court also held that the best method requirement under Section 10(4)(b) had not been satisfied.<\/p>\n\n\n\n<p>Though several communication methods were mentioned, the specification failed to disclose which method constituted the best mode known to the inventor for implementing the invention.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"important-precedents-relied-upon\"><span class=\"ez-toc-section\" id=\"Important_Precedents_Relied_Upon\"><\/span>Important Precedents Relied Upon<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Case<\/th><th>Legal Principle<\/th><\/tr><\/thead><tbody><tr><td>Farbwerke Hoechst v.

court&#8217;s treatment of the inventive step objection.<\/p>\n\n\n\n<p>The court observed that prior art document D1 could not have been relied upon because:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>D1 was published on 10.08.2006.<\/li>\n\n\n\n<li>The subject patent application had already been filed on 03.08.2006.<\/li>\n<\/ul>\n\n\n\n<p>Therefore, D1 was not valid prior art against the application.<\/p>\n\n\n\n<p>Consequently, the objection relating to lack of inventive step under Section 2(1)(ja) did not survive.<\/p>\n\n\n\n<p>Nevertheless, despite the appellant overcoming the inventive step objection, the court held that the patent application still failed because of insufficiency of disclosure and lack of fair basis under Sections 10(4)(a) and 10(5).<\/p>\n\n\n\n<p>The Court concluded that the specification did not provide enough information for a PSITA to implement the invention without conducting further research and experimentation.<\/p>\n\n\n\n<p>Since the essential technical architecture and operational methodology were absent, the invention failed the enablement requirement.<\/p>\n\n\n\n<h2

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The Delhi High Court dismissed the appeal and upheld the rejection of Patent Application No. 1774\/DEL\/2006.<\/p>\n\n\n\n<p>The Court held that the invention suffered from insufficiency of disclosure under Section 10(4)(a) of the Patents Act, 1970, because the complete specification failed to fully describe the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The operation of the invention<\/li>\n\n\n\n<li>The implementation methodology<\/li>\n\n\n\n<li>The best mode of performing the invention<\/li>\n<\/ul>\n\n\n\n<p>The Court also held that the claims were not fairly based on the complete specification and therefore violated Section 10(5) of the Patents Act.<\/p>\n\n\n\n<p>Accordingly, the rejection order dated 31.01.2014, passed by the Assistant Controller of Patents, was sustained.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"point-of-law-settled\"><span class=\"ez-toc-section\"
