Critical Analysis: Intra-Cellular Therapies, Inc. v. Controller of Patents

  Critical Analysis: Intra-Cellular Therapies, Inc. v. Controller of Patents (2026:DHC:5394) C.A.(COMM.IPD-PAT) 24/2023 | Delhi High Court | Decided: 06.07.2026 I. Doctrinal Analysis: Novelty and the "Coverage vs. Disclosure" Question A. The genus-species anticipation problem The core novelty dispute was a classic Markush-genus-versus-species-selection issue. The appellant argued that arriving at the claimed species from the generic Formula I of D1/D7 required " multiple selections " among independent variables (R1–R6), and that the Controller impermissibly relied on more than one prior art document to construct a single "closest prior art" novelty attack — a submission with real doctrinal pedigree, since novelty (unlike obviousness) is ordinarily tested against a single prior document read as a whole. The Court's response — invoking AstraZeneca AB and Boehringer Ingelheim v. Vee Excel — collapses the " covered vs. disclosed " dist...

Keyword Advertising and Trademark Infringement: MakeMyTrip India Pvt. Ltd. v. Booking.com B.V. & Ors.

Background By order dated April 27, 2022, Justice Pratibha M. Singh of the Delhi High Court granted an interim injunction in favor of MakeMyTrip India Private Limited ("MMT") in its suit against Booking.com B.V. and others. MMT had sued to protect its registered trademarks "MakeMyTrip" and its variants, which Booking.com was using as keywords on Google's Ads Program to trigger its own advertisements in Google search results. MMT's grievance was that a search for "MakeMyTrip" frequently displayed, as the very first result in the advertisement category, a sponsored listing for Booking.com — one of MMT's principal competitors. MMT argued that such use of its registered mark by a direct competitor amounted to trademark infringement. Booking.com's Defense Booking.com resisted the injunction on several grounds: It relied on the European Commission's decision in Case AT.40428 — Guess , dated December 17, 2018 (the " Guess decision"...

Myanmar's New Trademark Law: A Shift Toward a Modern Registration System

On January 30, 2019, the Parliament of Myanmar passed the country's first modern Trademark Law, marking a significant step toward aligning Myanmar's intellectual property regime with international standards. This legislation will replace the existing practice—under which trademark rights are secured merely by registering a Declaration of Ownership with the Office of the Registration of Deeds—with a formal, examination-based trademark registration system. To administer this new regime, Myanmar will establish an Intellectual Property Office ("IPO") under the Ministry of Commerce. Transition for Existing Registrations Recognizing that numerous trademarks are already on record under the old declaration-based system, the IPO will introduce a "soft-opening" period, commencing in January 2020, during which owners of existing registrations may re-file their marks with the IPO. This re-filing window will remain open for six (6) months, and re-filed marks will be a...

Patent (Amendment) Rules, 2019: Expanded Scope for Expedited Examination

The Patent (Amendment) Rules, 2019 came into effect on September 17, 2019, introducing significant changes to the framework governing expedited examination of patent applications in India. Rule 24(C) has been amended to expand the categories of applicants eligible for expedited examination. Previously limited to a narrow set of circumstances, the Rule now recognizes ten distinct categories under which an applicant may request expedited examination: Where India has been indicated as the International Searching Authority (ISA) or elected as the International Preliminary Examining Authority (IPEA) in the corresponding PCT application; Where the applicant qualifies as a start-up; Where the applicant qualifies as a small entity; Where the applicant(s) is/are natural person(s), and at least one such applicant is a female; Where the applicant is a Government Department; Where the applicant is an institution established by a Central, Provincial, or State Act, and is owned or controlled...

Madrid Protocol vs. Direct Filing in India: A Comparative Analysis

India became a member of the Madrid Protocol on July 8, 2013. At the time, the advantages of filing through the Madrid System were substantial when compared to filing a Convention or ordinary application directly in India. Initial Advantages of the Madrid Route Under the Madrid System, there was no limitation on the number of goods or services that could be listed in the specification. By contrast, applicants filing directly in India were required to pay additional fees for every character beyond 500 (excluding spaces) in the description of goods or services. Furthermore, Madrid applicants were not required to pay an association fee, whereas direct applicants with prior pending or registered applications for the same mark were liable to pay an association fee for each such prior application. Additional benefits of the Madrid route included savings on attorney fees and the convenience of centralized management of a trademark portfolio across multiple jurisdictions. Narrowing of the ...

Trademark Amendment Rules 2017: A Practitioner's Analysis

The Trademark Amendment Rules, 2017 came into force on March 6, 2017, marking one of the most significant overhauls of India's trademark procedural framework in recent years. As a practitioner who has worked with the earlier framework for years, I have set out below a detailed analysis of the key changes, their practical implications, and what applicants, brand owners, and startups should watch for going forward. 1. Consolidation of Forms: A Welcome Simplification One of the most immediately visible — and genuinely positive — changes brought about by the 2017 Rules is the drastic reduction in the number of forms prescribed for trademark proceedings. Under the earlier regime, practitioners had to navigate a bewildering array of forms, each tied to a narrow, specific type of application or proceeding. This fragmented structure often led to confusion, procedural delays, and inadvertent errors arising from the use of an incorrect form. The amended Rules have consolidated this mul...

Jurisdiction Under Section 62 of the Copyright Act and Section 134 of the Trade Marks Act: The Supreme Court's Ruling in Indian Performing Rights Society Ltd. v. Sanjay Dalia

The Question Before the Court In Indian Performing Rights Society Ltd. v. Sanjay Dalia , the Supreme Court was called upon to settle a recurring and commercially significant question: where a plaintiff's principal place of business is at a location where the cause of action has also arisen, can the plaintiff nonetheless choose to sue at a different place — typically the location of a branch office — merely because it also carries on business there? The Court answered this decisively in the negative, holding that Section 62 of the Copyright Act, 1957 and Section 134 of the Trade Marks Act, 1999 must be construed purposively, and that a plaintiff residing or carrying on business at a place where the cause of action has also wholly or partly arisen must institute the suit at that place. The Statutory Scheme Section 20 of the Code of Civil Procedure ordinarily determines where a suit may be filed: under clauses (a) and (b), at a place where the defendant resides or carries on busin...

Customs Enforcement of Intellectual Property Rights: The IPR (Imported Goods) Enforcement Rules, 2007

Overview The Intellectual Property Rights (Imported Goods) Enforcement Rules, 2007 empower Indian customs authorities to suspend the clearance of infringing goods, provided the rights holder has registered a notice to that effect. In practice, however, this mechanism remains significantly underused by registered proprietors and owners of intellectual property rights. Registering such a notice gives the IP owner a valuable layer of border protection against the import of infringing goods, particularly in relation to copyrights, trademarks, and designs. Patents are also covered under the Rules, but patent-related border enforcement is comparatively rare in practice, given the greater technical complexity and specialized expertise required to assess infringement at the border. Filing the Notice A notice of registration must be filed together with: a certified copy of the relevant IP right; an annexure setting out details of the right holder's rights and the grounds on which re...
