step under Section 2(1)(ja) and non-patentability under Section 3(d) of the Patents Act, 1970.<\/p>\n\n\n\n<p>The court found that although the controller discussed product claims, the process claims forming part of the same application were completely ignored.<\/p>\n\n\n\n<p>The ruling highlights the importance of the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Procedural

Co.

December 2012.<\/p>\n\n\n\n<p>The application claimed priority from Korean Priority Application No. 10-2011-0146818 dated 30 December 2011.<\/p>\n\n\n\n<p>The invention related to <strong>thieno[3,2-d]pyrimidine derivatives<\/strong> and their pharmaceutical applications.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"first-examination-report-and-objections\"><span

class=\"wp-block-list\">\n<li>Novelty<\/li>\n\n\n\n<li>Inventive step<\/li>\n\n\n\n<li>Section 3(d)<\/li>\n<\/ul>\n\n\n\n<p>After the hearing conducted on 13 May 2021, the appellant submitted written

Before the Court<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The principal dispute before the court was whether the patent controller had legally and properly examined the patent application before rejecting it.<\/p>\n\n\n\n<p>The appellant argued that the Controller failed to consider Claims 14 to 22, which were process claims relating to the method of preparing the claimed compounds.<\/p>\n\n\n\n<p>According to the appellant, the impugned order discussed only Claims 1 to 13 dealing with the compound itself and did not analyse the independent process claims at all.<\/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

id=\"response-by-the-patent-office\"><span class=\"ez-toc-section\" id=\"Response_by_the_Patent_Office\"><\/span>Response by the Patent Office<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The respondent patent office defended the rejection on the basis of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lack of inventive step<\/li>\n\n\n\n<li>Section 3(d) objections<\/li>\n<\/ul>\n\n\n\n<p>However, during the hearing before the High Court, the Court specifically questioned whether the process claims had been examined in the impugned order.<\/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 noted that the Controller had analysed only the product claims by comparing them with cited prior art documents D1 and D2. However, there was complete silence regarding claims 14 to 22, which specifically related to the process for preparing the claimed compound.<\/p>\n\n\n\n<p>The Court observed that Claim 1 covered the compound described as a \u201cthieno[3,2-d]pyrimidine derivative of formula (I)\u201d or its pharmaceutically acceptable salts, whereas Claim 14 independently claimed a method of preparation involving three steps. The court emphasised that process claims and product claims are legally distinct categories of patent claims, and each requires separate examination on its own merits.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"distinction-between-product-and-process-claims\"><span class=\"ez-toc-section\" id=\"Distinction_Between_Product_and_Process_Claims\"><\/span>Distinction Between Product and Process Claims<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>Claim Type<\/th><th>Description<\/th><th>Court\u2019s Observation<\/th><\/tr><\/thead><tbody><tr><td>Product Claims<\/td><td>Related to the compound itself<\/td><td>Examined by the Controller using prior art documents D1 and D2<\/td><\/tr><tr><td>Process Claims<\/td><td>Related to the method of preparation<\/td><td>Claims 14 to 22 were not examined in the impugned order<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>A significant aspect of the judgement was the court&#8217;s emphasis on reasoned adjudication. The Court held that when an applicant places multiple categories of claims before the Patent Office, the Controller is duty-bound to examine each category and provide reasons for acceptance or rejection. Failure to do so amounts to non-application of mind and renders the order unsustainable.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"importance-of-reasoned-adjudication\"><span class=\"ez-toc-section\" id=\"Importance_of_Reasoned_Adjudication\"><\/span>Importance of Reasoned Adjudication<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The Patent Office must examine every category of claim independently.<\/li>\n\n\n\n<li>Reasoned findings are mandatory for acceptance or rejection.<\/li>\n\n\n\n<li>Non-examination of material claims amounts to non-application of mind.<\/li>\n\n\n\n<li>Quasi-judicial authorities must provide comprehensive reasoning.<\/li>\n<\/ul>\n\n\n\n<p>The Court also recorded that, pursuant to a judicial query raised on 23 April 2026, the learned Central Government Standing Counsel appearing for the respondent admitted during the hearing on 4 May 2026 that the process claims had not been dealt with in the impugned order. This admission became an important factor in the court&#8217;s reasoning.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"court-observations-on-patent-adjudication\"><span class=\"ez-toc-section\" id=\"Court_Observations_on_Patent_Adjudication\"><\/span>Court Observations on Patent Adjudication<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Although the judgement does not undertake a detailed substantive analysis of Section 3(d) or inventive step jurisprudence, it reinforces broader administrative law principles applicable to patent adjudication. The decision aligns with settled judicial principles that quasi-judicial authorities must provide reasoned findings on all material issues raised before them. The judgement reflects the growing trend in Indian intellectual property jurisprudence requiring higher standards of examination and transparency from the Patent Office.<\/p>\n\n\n\n<p>The Court did not finally decide the patentability of the invention itself. Instead, it focused on procedural legality and fairness in examination. This approach is important because appellate courts in patent matters frequently avoid substituting technical examination with judicial opinion unless absolutely necessary.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"final-decision-of-the-court\"><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>The Delhi High Court set aside the impugned order dated 25 April 2022 passed by the Controller of Patents and Designs. The matter was remanded back to the Patent Office for fresh consideration on merits after granting the appellant a fresh hearing opportunity.<\/p>\n\n\n\n<p>The court directed the controller to reconsider the matter independently and in accordance with law without being influenced by observations contained in the judgement. The Court further directed that the reconsideration be completed within six months from the date of the judgement. Additionally, the Court directed that a copy of the order be placed before the Controller General of Patents, Designs and Trademarks for necessary administrative action.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"key-directions-issued-by-the-court\"><span class=\"ez-toc-section\" id=\"Key_Directions_Issued_by_the_Court\"><\/span>Key Directions Issued by the Court<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Impugned order dated 25 April 2022 was set aside.<\/li>\n\n\n\n<li>Matter remanded for fresh consideration on merits.<\/li>\n\n\n\n<li>Fresh hearing opportunity to be granted to the appellant.<\/li>\n\n\n\n<li>Controller to decide the matter independently and in accordance with law.<\/li>\n\n\n\n<li>Reconsideration to be completed within six months.<\/li>\n\n\n\n<li>Order to be placed before the Controller General for administrative action.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"point-of-law-settled-in-the-case\"><span class=\"ez-toc-section\" id=\"Point_of_Law_Settled_in_the_Case\"><\/span>Point of Law Settled in the Case<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The judgement establishes that while examining a patent application, the Patent Office must independently consider and adjudicate all categories of claims, including product claims and process claims.
