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...

DESIGN REGISTRATION AS A DEFENCE IN AN INFRINGEMENT SUIT

 A Critical Analysis of Whirlpool of India Ltd. v. Videocon Industries Ltd.

(S. J. Kathawalla, J., Bombay High Court, Notice of Motion No. 2269 of 2012 in Suit No. 2012 of 2012, decided May 27, 2014)

Core question: Can an infringement suit under Section 22 lie against a person who is himself a registered proprietor of a design? And, on the facts, was there infringement and passing off?

Core statutory provisions: Sections 2(c), 6, 11, 19 and 22, Designs Act, 2000

I. Introduction

The Designs Act, 2000 grants a registered proprietor a time-bound monopoly over the visual features of an article, but it does not say, in so many words, whether that monopoly can be enforced against another person who has himself managed to register a similar or identical design. Whirlpool of India Ltd. v. Videocon Industries Ltd. is the leading Bombay High Court authority answering this question, and it did so by adopting — and thereby entrenching — the position first taken by the Delhi High Court in Micolube India Ltd. v. Rakesh Kumar (decided along with Mohan Lal v. Sona Paint & Hardwares). Read together with the Calcutta High Court's contrary view in Kent RO Systems Ltd. v. Sandeep Agarwal, the trilogy exposes a genuine and, to date, unresolved split among the High Courts on whether design registration can operate as a defence to an infringement suit. This article examines the Whirlpool judgment in detail — its facts, the rival submissions, and the Court's reasoning — before situating it within this larger doctrinal conflict and tracing what has (and has not) changed since 2014.

II. Factual Background

Whirlpool of India Ltd., a subsidiary of the American home-appliance major Whirlpool Corporation, was the registered proprietor of two designs governing the shape, configuration and colour scheme of its semi-automatic washing machines — a distinctive combination of a squarish body on one side and a rounded contour on the other, finished in a signature two-tone colour scheme. Both registrations were valid and subsisting at the relevant time.

Whirlpool instituted a suit (Notice of Motion No. 2269 of 2012 in Suit No. 2012 of 2012) against Videocon Industries Ltd., alleging that Videocon's competing semi-automatic washing machine was, on a visual comparison, indistinguishable from its registered design, and that Videocon had additionally copied its distinctive colour combination — amounting to an obvious and fraudulent imitation actionable under Section 22 of the Designs Act, and simultaneously giving rise to a passing-off claim.

The procedural history is important to the legal question that came to dominate the case. The learned Single Judge (Gavai, J.) granted an ad-interim injunction restraining Videocon on 25 July 2012. Videocon's challenge to that order failed before the Division Bench (Mohit Shah, C.J. and Jamdar, J.) on 13 August 2012. Videocon then filed a Special Leave Petition before the Supreme Court against the Division Bench's order. Crucially, in the interim between the Division Bench's ruling and the filing of the SLP, Videocon applied for — and was granted — registration of the design applied to its own washing machine, marketed as the "Videocon Pebble". Because this registration was obtained after the Division Bench had already ruled (even though the application predated the suit), the Supreme Court considered it appropriate to await the outcome of the pending Notice of Motion, which would necessarily have to grapple with the question of whether Videocon's own registration afforded it any defence. It was this Notice of Motion that Kathawalla, J. decided on 27 May 2014 — the judgment discussed in this article.

III. Whirlpool's Arguments (the Plaintiff / "Appellant" side of the record)

(a) On maintainability — "any person" in Section 22 means any person

     Section 22 confers a right of relief against "any person" who applies a registered design (or an obvious or fraudulent imitation of it) to an article without consent. This phrase must be given its plain, unqualified meaning — it is not restricted to non-registrants.

     Where the Legislature intended to carve registered proprietors out of a provision, it said so expressly — for instance, Section 16 qualifies "any person" with the words "other than the registered proprietor". The deliberate absence of that qualifying phrase in Section 22 shows a considered legislative choice to leave the class of potential defendants unrestricted.

     Section 22(3) already tells us what defences are open to a defendant: every ground available for cancellation of a design under Section 19. A subsequent registration in the defendant's own name is not a Section 19 ground and therefore cannot be read into Section 22(3) by implication.

     Videocon's registration, in any event, was obtained after Whirlpool's and after the Division Bench had already confirmed the injunction — it could not retrospectively legitimise conduct that was infringing when it began.

(b) On infringement

     Applying the settled visual-comparison test from Castrol India Ltd. v. Tide Water Oil Co. (I) Ltd. and Kemp & Co. v. Prima Plastics Ltd. — whether, judged by the eye and through the imperfect recollection of an ordinary purchaser, the essential features claimed as new and original in the registered design are reproduced in the defendant's article — Videocon's washing machine was a slavish, brazen copy, right down to the two-tone colour combination.

(c) On the defences raised by Videocon

     Functionality: the features claimed were the external shape, configuration and colour scheme — not the internal drum or washing mechanism. Numerous alternative external shapes exist in the market for machines performing the identical function, so the design was not functionally dictated.

     Novelty: Videocon, which had manufactured washing machines for decades without ever producing anything resembling Whirlpool's design, could not credibly claim the design was a mere trade variant lacking novelty. Further, having itself sought and obtained registration for an identical design, Videocon was estopped from arguing that the very same design lacked novelty or originality (Asian Rubber Industries Ltd. v. Jasco Rubber).

     Two registrations on the same day: the two registrations obtained by Whirlpool with minor variations were permissible under Sections 6(3) and 6(4), which specifically contemplate fresh registration of a modified design by the same proprietor.

(d) On passing off

     Whirlpool's washing machines had, through years of sales and advertising, acquired substantial goodwill and reputation attaching specifically to their distinctive shape and colour scheme.

     Videocon's imitation amounted to misrepresentation likely to deceive a class of purchasers — including semi-literate and rural buyers relying on fleeting recollection or word-of-mouth rather than close brand scrutiny — into believing they were purchasing, or a product associated with, Whirlpool.

IV. Videocon's Arguments (the Defendant / "Respondent" side of the record)

(a) On maintainability — no suit lies against a registered proprietor

     Section 11, read with Section 2(c), confers on a registered proprietor an exclusive "copyright" to apply the design — a substantive statutory right that a court cannot simply override. "Any person" in Section 22 must therefore be read as "any person other than a registered proprietor", consistently with the scheme of the Act.

     The only mechanism by which a registered design can be challenged is cancellation under Section 19 before the Controller (or as a defence under Section 22(3)); permitting a parallel infringement suit against a registered proprietor would make the Section 19 mechanism redundant and allow courts to indirectly nullify a subsisting registration without following the statutory cancellation route.

     Videocon held its own registration for the "Videocon Pebble" design, obtained (on application) even before certain stages of the litigation, and this registration should operate as a complete answer to the infringement claim.

(b) On the merits

     Functionality: the external contours of a semi-automatic washing machine are substantially dictated by functional and ergonomic constraints common to the category of product.

     Lack of novelty: Whirlpool's design was no more than a combination of known, pre-existing trade features and shapes, and did not meet the "substantial novelty" threshold set out in B. Chawla & Sons v. Bright Auto Industries.

     The two same-day registrations obtained by Whirlpool, differing only in minor respects, showed that even minor variations were treated by the Controller as sufficient for a fresh registration — and, a fortiori, Videocon's design, which differed from Whirlpool's to a materially greater degree, could not be regarded as an infringing imitation.

     On passing off, Videocon argued that purchasers of washing machines buy primarily on brand and price, not on the external shape or colour of the appliance, so there could be no actionable misrepresentation; it also relied on the fact that its machines were typically sold only after an in-store demonstration, reducing any risk of confusion at the point of sale.

V. The Court's Reasoning

(a) Maintainability: Section 11 is expressly subject to the rest of the Act

The Court rejected Videocon's threshold objection. Section 11's grant of exclusive rights to the registered proprietor is itself made "subject to the provisions of this Act" — meaning that if other provisions (chiefly Section 22, read with Section 19) empower a court to find infringement or to direct cancellation of a design, Section 11 cannot be invoked as a bar on the exercise of that power. The Court held, in terms that have since been repeatedly quoted:

"Just as the Plaintiff cannot claim a right to relief under Section 22 against a prior registered proprietor on the basis of his own registration, the Defendant cannot successfully defend an action under Section 22 by a prior registered proprietor on the basis of his own registration."

The Court reasoned that Section 22(3) is the exhaustive list of defences available in an infringement suit — every ground on which a registration may be cancelled under Section 19 — and that a subsequent registration, standing alone, does not appear anywhere in that list. It further drew on the contrast between Section 16 (which expressly excludes the registered proprietor from the class of "any person") and Section 22 (which contains no such exclusion), concluding that the Legislature's silence in Section 22 was deliberate rather than accidental. Sections 19 and 22 were also held to operate in distinct spheres: a Section 19 cause of action arises from the mere fact of a (later) registration being granted, whereas a Section 22 cause of action arises only when a registered design is actually applied to an article for sale. Since Videocon was using its design commercially, Section 22 was squarely available to Whirlpool irrespective of Videocon's own subsequent registration. The touchstone that emerges is temporal priority: the prior registrant may sue a subsequent registrant, but not vice versa.

(b) Infringement on the merits

Applying the visual-comparison test from Castrol India Ltd. v. Tide Water Oil Co. (I) Ltd. and Kemp & Co. v. Prima Plastics Ltd. — essential features judged through the eye of the purchaser — the Court, after physically comparing both washing machines produced in court alongside comparative charts, concluded that Videocon had "slavishly/brazenly copied" Whirlpool's design, including its two-tone colour scheme, and granted the injunction.

(c) The functionality defence

The Court held that a functionality defence succeeds only where the claimed design is the sole possible form dictated by the article's function — it is not enough that the form has some relevance to function. Since semi-automatic washing machines are manufactured in numerous different external shapes performing the identical function, Whirlpool's external shape and configuration had no necessary connection to functionality, and the defence failed.

(d) The novelty defence

The Court rejected the novelty challenge for two reasons: first, Videocon's own decades-long manufacturing history without producing anything similar was treated as evidence of the design's originality; and second, having itself obtained registration for what was effectively the same design, Videocon could not simultaneously argue that the design lacked novelty, following the Division Bench ruling in Asian Rubber Industries Ltd. v. Jasco Rubber.

(e) The two same-day registrations

The Court read Sections 6(3) and 6(4) as creating a specific exception permitting a registered proprietor to obtain a fresh registration — for the same design applied to other articles, or with minor modifications to the same article — precisely because the registrant and applicant are identical. Whirlpool's two registrations fell squarely within this statutory scheme and did not, therefore, undermine either registration's validity or novelty.

(f) Passing off

The Court found substantial goodwill and reputation attaching to the distinctive shape, get-up and colour scheme of Whirlpool's machines. On misrepresentation, it accepted Whirlpool's submission that purchasers of semi-automatic washing machines — a category the Court characterised as including less-discerning, sometimes semi-literate or rural buyers relying on fleeting glimpses, word-of-mouth or advertisements rather than close brand scrutiny — were likely to mistake Videocon's product for Whirlpool's. Pre-sale demonstrations, the Court held, did not eliminate this risk, since a confused purchaser might watch such a demonstration already believing the product to be Whirlpool's. The passing-off claim was accordingly upheld alongside the design-infringement claim.

VI. Does Design Registration Offer a Defence in an Infringement Suit?

Whirlpool answers this question with some precision, and the answer is qualified rather than absolute. Section 22(3) of the Designs Act makes available, as a defence to an infringement action, only the grounds on which a registration may be cancelled under Section 19 (for example, prior publication, lack of novelty or originality, or non-registrability of the subject matter). The mere fact that the defendant also holds a registration for a similar or identical design is not, in itself, one of those grounds — and is therefore not, without more, a defence.

The position is asymmetric and turns on priority in time. A prior registrant retains the right to sue a later registrant for infringement under Section 22, and may separately seek cancellation of the later registration under Section 19. A later registrant, by contrast, cannot invoke his own registration as a shield against the prior registrant, precisely because his registration could itself be vulnerable to cancellation on the ground that an identical or substantially similar design was already registered and therefore lacked the novelty required for a valid grant. In other words, registration is a sword that can be used offensively against later imitators, and a defence only for the earliest registrant — it is not, by itself, a universal safe harbour for whoever manages to register second.

This should be distinguished from the true statutory defences that do operate as complete answers to an infringement claim: proof that the defendant's own registration is, in truth, prior in time; proof that the plaintiff's registration is liable to cancellation on one of the Section 19 grounds (which triggers mandatory transfer of the suit to the High Court under Section 22(4)); or proof of a contractual licence under Section 22 sub-section (3) concerning restrictive conditions. Mere possession of a design registration, without reference to priority or to the Section 19 grounds, is not among them.

VII. Whirlpool in Light of Micolube India Ltd. v. Rakesh Kumar and Mohan Lal v. Sona Paint & Hardwares

The maintainability question in Whirlpool did not arise in a vacuum. A year earlier, in Micolube India Ltd. v. Rakesh Kumar (heard together with Mohan Lal, Proprietor of Mourya Industries v. Sona Paint & Hardwares), a Full Bench of three judges of the Delhi High Court had been constituted specifically to resolve a reference on three questions of law:

1.  Whether a suit for infringement of a registered design is maintainable against another registered proprietor of a design under the Designs Act, 2000;

2.  Whether a remedy of passing off is available in relation to a design, given that the Designs Act contains no express saving of common-law rights; and

3.  Whether a claim of passing off can be joined with a claim for design infringement in a single, composite suit.

By a 2:1 majority, the Full Bench answered Question 1 in the affirmative — a holder of a registered design can institute a suit against a defendant who is also in possession of a registered design — reversing the more restrictive view that had been taken at the single-judge reference stage. It also held that a passing-off remedy is, in principle, available in relation to a design used as a trade mark. On Question 3, however, the Full Bench held that a composite suit combining design infringement and passing off could not be filed; the two causes of action would have to be instituted separately, though the court retained a discretion to try them together where they were filed in close proximity and shared common questions.

Whirlpool expressly followed and applied the Micolube/Mohan Lal ratio on the first question, extending it beyond Delhi and giving it cross-jurisdictional force: the Bombay High Court held, in almost identical language, that Section 11's monopoly is subject to the rest of the Act and that "any person" in Section 22 is not confined to non-registrants. This alignment between Delhi and Bombay is the principal reason Whirlpool is treated as a leading authority on the point today.

On the third question, however, Whirlpool sits somewhat uneasily beside Mohan Lal, because Kathawalla, J. adjudicated the design-infringement claim and the passing-off claim together, in the same Notice of Motion, without treating Mohan Lal's composite-suit bar as an obstacle.

Note- Editorial update: Written shortly after the judgment, this article flagged that tension without the benefit of what was still to come — the two developments below were not yet on the books in 2014, and are accordingly presented as later editorial updates rather than as part of the original 2014 analysis.

Editorial Update — 2017

This tension between Bombay and Delhi practice on joinder was made explicit in Cello Household Products v. Modware India (Bombay High Court, 2017), which expressly declined to follow Mohan Lal and allowed both causes of action — design infringement and passing off — to proceed together in a single suit.

This confirmed that Bombay's practice, as exemplified by Whirlpool itself, had diverged from the Delhi position on composite suits well before Delhi revisited its own rule.

Editorial Update — 2018

The Delhi High Court itself ultimately revisited the point. A Special Bench of five judges in Carlsberg Breweries A/S v. Som Distilleries and Breweries Ltd. (14 December 2018) overruled Mohan Lal on the composite-suit question, holding — by reference to Order II Rule 3 of the Code of Civil Procedure and the Supreme Court's guidance in cases such as Dabur India Ltd. v. K.R. Industries — that claims for design infringement and passing off arising from the same facts can properly be joined in a single suit, since keeping them apart would only multiply litigation without any corresponding benefit.

It bears emphasis that Carlsberg Breweries overruled Mohan Lal only on the composite-suit question (Question 3). It did not revisit, and had no occasion to revisit, the Full Bench's answer to Question 1 — the maintainability of an infringement suit against another registered proprietor — which remains good law in Delhi, and which Whirlpool continues to apply in Bombay.

VIII. The Contrary View: Kent RO Systems Ltd. v. Sandeep Agarwal

Barely months before Whirlpool was decided, the Calcutta High Court took the opposite position on precisely the same question. In Kent RO Systems Ltd. v. Sandeep Agarwal (order dated 30 January 2014), Kent held a registered design for a water purifier. The defendant sold a similar purifier under a different trademark, pursuant to authorisation from a subsequent registered proprietor of a similar design. Kent had neither impleaded that subsequent registrant nor sought cancellation of his registration under Section 19; it simply sued the defendant for infringement, and its interim injunction was vacated.

The Calcutta High Court declined to follow the majority view in Micolube, finding the dissenting opinion within that Full Bench more persuasive. It held that a registered proprietor cannot maintain an infringement suit against a subsequent registrant; his remedy, if his rights are genuinely in jeopardy, is to seek cancellation of the later registration under Section 19 — not to sue for infringement while the later registration subsists. The Court reasoned that, unlike the trade mark regime (which involves examination, publication and a formal opposition process before a mark is registered), the Designs Act contains no comparable mechanism by which a fresh applicant's design is tested against an existing registrant's design before grant; consequently, every registered proprietor stands on an equal statutory footing so long as copyright subsists in his design, and there can be no assertion of monopoly — whether through infringement or passing off — against a co-equal registrant.

The result is a genuine, live conflict: the Delhi High Court (Micolube, 2013) and the Bombay High Court (Whirlpool, 2014) hold that a prior registrant can sue a subsequent registrant for infringement, subject only to the Section 19 grounds as a defence; the Calcutta High Court (Kent RO Systems, 2014) holds that no such suit lies at all, and that cancellation under Section 19 is the exclusive remedy.

Rows shaded amber are post-2014 editorial updates (see Sections VII and IX) and were not part of the original 2014 analysis of Whirlpool.

IX. Other High Courts and the Supreme Court

As of 2014, the Supreme Court had not laid down an authoritative ruling squarely resolving whether an infringement suit is maintainable against a subsequent registered proprietor. In the Whirlpool-Videocon litigation itself, the Supreme Court had an opportunity to consider the point when Videocon filed a Special Leave Petition against the Division Bench's confirmation of the interim injunction; rather than deciding the legal question itself, the Supreme Court chose to await the Bombay High Court's ruling on the pending Notice of Motion — the very decision discussed in this article — since that ruling would necessarily address the maintainability issue. This is itself telling: even at the apex level, the question was treated as one requiring careful High Court elaboration rather than summary disposal. Everything that follows in this section happened after 2014 and is therefore presented, case by case, as a dated editorial update rather than as part of the original analysis.

Editorial Update — 2015

The same parties went on to litigate a related dispute before the Karnataka High Court over Whirlpool's registered refrigerator design (bottom-mounted drawer design, including Design Registration No. 198386) — Videocon Industries Ltd. v. Whirlpool of India Ltd., decided February 2, 2015.

That dispute centred on novelty and prior-art defences rather than on the maintainability question, and so does not add to, or detract from, the Delhi/Bombay–Calcutta divide discussed above.

Editorial Update — 2017

Kent RO Systems Ltd. v. Amit Kotak (Delhi High Court, January 18, 2017) — an unrelated dispute over the same plaintiff's water-purifier designs, this time against an e-commerce intermediary — proceeded on the settled premise that a design-infringement suit lies against another registered proprietor, without any need to revisit that threshold question.

Its relevance here is confirmatory rather than doctrinal: it shows Delhi courts continuing to apply the Micolube ratio as settled law three years after Whirlpool.

Editorial Update — 2020

The Supreme Court's most relevant intervention since 2014 has been S.D. Containers, Indore v. Mold Tek Packaging Ltd. (2020), which clarified only the procedural meaning of "High Court" for the purpose of Section 22(4) transfer where Section 19 grounds are raised as a defence.

This clarified procedure, not substance — it did not touch, and had no occasion to touch, the maintainability question addressed in Whirlpool.

Editorial Update — 2021

Kent RO Systems Ltd. v. Jaideep Kishnani (Delhi High Court, March 9, 2021) is a further instance of the same pattern: a design-infringement suit proceeding against a fellow trader without the maintainability question being reopened.

Taken together, these post-2014 developments confirm that Delhi and Bombay have continued to apply Whirlpool's premise without disturbance, while the Supreme Court has still not resolved the Delhi/Bombay–Calcutta divergence identified above. A litigant's forum choice can therefore still, in principle, affect the outcome on this threshold issue.

X. Key Takeaways

     A design registration does not, by itself, immunise its holder from an infringement suit brought by an earlier registrant — at least in Delhi and Bombay. The only defences available under Section 22(3) are the Section 19 cancellation grounds, and a subsequent registration is not one of them.

     Priority in time is decisive: a prior registrant can sue a later registrant; a later registrant cannot use his own registration defensively against the prior registrant, though he may separately seek to have the prior registration cancelled if genuine grounds exist.

     Whirlpool v. Videocon is significant chiefly for extending the Delhi High Court's Micolube/Mohan Lal ratio on maintainability to the Bombay High Court, giving it cross-jurisdictional weight — while at the same time illustrating (via its treatment of the passing-off claim in the same proceeding) the parallel, and in 2014 still-unresolved, dispute over composite suits (see the 2017 and 2018 editorial updates above for how that dispute was eventually settled).

     The Calcutta High Court's Kent RO Systems v. Sandeep Agarwal represents a genuine and still-unresolved divergence: it holds that no infringement suit lies against a subsequent registrant at all, and that cancellation under Section 19 is the exclusive remedy.

     The functionality defence requires the claimed design to be the only possible form dictated by function — mere functional relevance is not enough.

     Estoppel plays an important, if under-theorised, role: a defendant who has himself sought registration of a similar or identical design will generally not be permitted to simultaneously argue that the design lacks novelty.

     The Supreme Court has not yet resolved the Delhi/Bombay–Calcutta divergence on maintainability; practitioners must therefore be alert to the forum-dependent outcome this split can produce.

XI. Conclusion

Whirlpool of India Ltd. v. Videocon Industries Ltd. is best understood not as a freestanding decision but as a pivotal link in an ongoing judicial conversation about the boundaries of design monopoly in India. On the narrow question posed by this article — whether registration of a design offers a defence in an infringement suit — the Bombay High Court's answer, following Delhi, is a qualified no: registration matters, but only priority in registration matters as a defence, and only within the four corners of the grounds Parliament chose to make available under Section 19. The Calcutta High Court's contrary view keeps that answer from being settled law across India, and the absence of Supreme Court guidance means the conflict persists over a decade after Whirlpool was decided. Until the apex court speaks, the safest counsel for a registered proprietor facing a rival's competing registration remains the one Whirlpool itself demonstrates: sue promptly, establish priority, and be prepared to meet — and see off — every Section 19 ground the rival can muster.

The Patent (Amendment) Rules, 2024: What the New Flexibility Gives You — and the Hard Deadlines It Cannot Touch

Introduction On 15 March 2024, the Patent (Amendment) Rules, 2024 came into force and quietly rewrote the rhythm of patent prosecution in India. Practitioners who had spent two decades telling clients "this deadline cannot be extended, full stop" suddenly found themselves revising standard advice: many timelines that were once immovable can now be bought back, at a price, under the liberalised Rule 138. But here lies the trap — and it is a trap that has already caught applicants who read the headlines and not the fine print. The 2024 amendments are subordinate legislation made under Section 159 of the Patents Act, 1970. They can soften only those timelines that live in the Rules . Where the Act itself fixes a period and attaches a consequence — "deemed abandoned," "deemed withdrawn," "shall not be entertained" — no Rule, however generously worded, can rescue a defaulting applicant.

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...
