Trademark Coexistence Agreements – strategy and drafting

Trademark coexistence agreements occupy a sophisticated and commercially consequential space within Indian intellectual property practice      one that sits at the junction of trademark law, contract law and competition law, yet is addressed by no single statute with dedicated clarity. In a trademark register that now carries over two and a half million active marks, with thousands of fresh applications filed every month, the probability that two independently adopted marks will resemble each other is not a remote theoretical risk but a daily commercial reality. Businesses that have built reputation and goodwill around a mark in good faith may find, upon seeking registration or upon expanding into a new territory or product category, that a conflicting mark already sits on the register or is already in use in the marketplace. The choice between aggressive litigation and negotiated coexistence is not merely a commercial preference it is a strategic IP decision with long-term legal consequences for the enforceability of the mark itself, the party’s freedom to operate and the stability of its brand in an increasingly integrated market.

A trademark coexistence agreement, at its most fundamental, is an agreement between two or more parties that allows conflicting marks to coexist in the commercial marketplace, subject to conditions. Under Indian trademark jurisprudence, these agreements acknowledge that not all similar marks would mislead consumers by incorporating different contexts, territories or industry sectors. The instrument is used across a wide spectrum of scenarios: to resolve opposition proceedings before the Trademark Registry, to settle pending infringement litigation, to structure the continued parallel use of historically concurrent marks and to manage the trademark consequences of family business partitions, corporate demergers or international brand expansions into the Indian market. What unites these diverse factual situations is the common legal challenge of enabling two parties to maintain lawful rights in marks that, to some degree, resemble each other without compromising the consumer’s ability to distinguish between them.

This article examines the legal framework for trademark coexistence under Indian law with the rigour and specificity the topic demands. It analyses the statutory foundation under the Trade Marks Act, 1999, the doctrine of honest concurrent use and its judicial interpretation, the strategic considerations that guide the decision to coexist rather than litigate, the essential elements of a well-drafted coexistence agreement, the enforceability of such agreements before the Trademark Registry and the courts, the interaction with competition law and the international dimensions of the instrument. Case law from the Delhi High Court, the Madras High Court and the Intellectual Property Appellate Board is examined throughout.

The Statutory Foundation – Section 12 and the Doctrine of Honest Concurrent Use

The statutory basis for permitting coexistence under Indian law lies in Section 12 of the Trade Marks Act, 1999, which empowers the Registrar to allow concurrent registration of identical or similar marks upon a finding of honest concurrent use or other special circumstances. Section 12 reads that notwithstanding the provisions of Section 11, the Registrar may permit the registration of a mark identical with or nearly resembling another mark already on the register if he is satisfied that there has been honest concurrent use of the marks or there exist other special circumstances which in the opinion of the Registrar make it proper for him to do so. The provision is deliberately broad the phrase “other special circumstances” confers a degree of residual discretion that allows the Registrar to respond to factual situations that do not fit neatly within the honest concurrent use template.

The legal architecture surrounding Section 12 is reinforced by Section 11 of the Act, which establishes the relative grounds for refusal. Section 11(1) prevents registration of a mark that is identical or similar to an earlier mark where there exists a likelihood of confusion on the part of the public. However, Section 11(10) provides that the Registrar shall not refuse registration by reason of Section 11(1) if the proprietor of the earlier trademark consents. This consent mechanism distinct from the honest concurrent use route under Section 12 is the statutory basis for the letter of consent, which has become a standard instrument in coexistence practice before the Registry. Together, Sections 11(10) and 12 create two parallel pathways for securing concurrent registration: one based on the senior proprietor’s consent and the other based on a factual demonstration of honest concurrent use supported by evidence of duration, geographical extent and consumer non-confusion.

The Delhi High Court in S. Syed Mohideen v. P. Sulochana Bai (2016) held that honest concurrent use of trademarks is legally allowed, subject to justifying circumstances. The Court’s formulation is notable for its acknowledgment that the doctrine does not operate as an automatic entitlement the party claiming honest concurrent use must positively establish the honesty of the adoption, the duration and extent of use and the absence of actual consumer confusion. The Supreme Court has observed that honest concurrent use depends on the facts of each case and that long and genuine use without dishonest intention can justify registration of similar trademarks, provided public confusion is minimal.

Judicial Interpretation – From Goenka to Lowenbrau

Indian courts have, over time, developed a nuanced and context-sensitive jurisprudence on trademark coexistence that moves well beyond the bare text of Section 12. The decisions of the Delhi High Court and the Madras High Court illustrate the judicial approach as one of active management rather than passive permission.

In a seminal case before the Delhi High Court, both parties sought to use the mark “Goenka” in connection with educational institutions. The court, after examining the factual matrix, permitted coexistence under Section 12, but crucially imposed a condition requiring the appellant to insert the name of their trust in brackets. The court treated Section 12 not as a passive permission but as an active instrument of judicial management, structuring the market relationship between two competing proprietors. The Goenka decision establishes a principle of enduring significance for coexistence agreement drafting: conditions imposed by courts or the Registrar under Section 12 whether territorial, class-based or typographic must be reflected in the coexistence agreement itself, since the agreement derives its legal standing partly from its conformity with the terms on which the Registrar or court has sanctioned the coexistence.

In Lowenbrau AG v. Japing Breweries Ltd., the Delhi High Court dealt with a trademark dispute over the use of the word “Lowenbrau” for beer products in India. The Court held that the word “Lowenbrau,” meaning lion’s drink in German, had long been used by multiple beer manufacturers and had become generic or publici juris. Taking into account the descriptive nature of the word and the long coexistence of the parties in different jurisdictions, the Court accepted the defence of honest concurrent use under Section 12 of the Trade Marks Act, 1999 and declined to grant an injunction. The Lowenbrau decision introduces a doctrinal refinement that practitioners must keep front of mind: where the element common to both marks has become generic or publici juris, the stronger ground for coexistence is the absence of distinctiveness rather than the presence of honesty. Coexistence agreements built around generic or descriptive elements are structurally weaker and more susceptible to challenge.

In N. Ranga Rao & Sons Pvt. Ltd. v. Sree Annapoorna Agro Foods, C.S. No. 259 of 2017, the Madras High Court addressed the coexistence of similar marks across different trademark classes. The plaintiff, N. Ranga Rao & Sons, was a major producer of incense sticks trading under the “Cycle” mark since 1954. The defendant had been producing edible oils under the same brand name since 2010. The court ruled that the plaintiff could not prevent the defendant from using the “Cycle” mark for edible oils, holding that there was no proof that the plaintiff sold edible oils using the contested mark and that components common to a trademark cannot be taken as grounds for infringement where the goods and services are radically different. The decision reinforces the principle that class-based separation a foundational device in coexistence agreements carries genuine legal weight in India, particularly where the commercial contexts are genuinely distinct.

The Intellectual Property Appellate Board, in Himalaya Drug Company v. SBL Ltd. (2013), engaged directly with the weight to be accorded to a coexistence agreement in assessing likelihood of confusion. The IPAB accorded great weight to the coexistence agreement while evaluating the likelihood of confusion, underlining that often the trade participants themselves understood more than what was actually happening in the market. This is a particularly significant holding from the perspective of agreement drafting: a well-structured coexistence agreement, containing specific mechanisms to avoid confusion and evidence of the parties’ mutual assessment that no consumer confusion in fact exists, carries persuasive evidentiary weight before both the Registry and the IPAB.

Strategic Considerations – Coexistence vs. Litigation

The decision to pursue a coexistence agreement rather than oppose, litigate or cancel must be grounded in a frank assessment of the parties’ respective positions, the costs of the alternatives and the long-term brand strategy of each party. Trademark litigation in India continues to be characterised by durations of three to seven years to reach final resolution, with even preliminary injunction proceedings continuing for months or years. This litigation timeline reality makes negotiated coexistence commercially attractive in a very large number of situations where the ultimate legal outcome is uncertain and the commercial disruption of prolonged dispute is disproportionate to the actual market conflict between the parties.

The strategic case for a coexistence agreement is strongest where several conditions are met. First, where both parties have a genuine, independently acquired history of use that predates the dispute the longer and more extensive that history on both sides, the more balanced the negotiating position and the more legitimate the claim to honest concurrent use. Second, where the commercial contexts of the two marks are genuinely distinct different classes of goods or services, different consumer demographics, different distribution channels or different geographic markets so that the structural conditions for consumer non-confusion are already present in the marketplace. Third, where the cost of rebranding or market withdrawal for either party would be disproportionate to the actual commercial overlap between them. In such circumstances, a well-structured coexistence agreement serves the interests of both parties and of the public far better than an expensive and uncertain enforcement campaign.

The case for coexistence is correspondingly weaker and the case for aggressive enforcement stronger where one party’s mark is genuinely well-known under Section 2(1)(zg) of the Trade Marks Act, 1999 and enjoys cross-class protection under Section 11(2), where the other party has adopted the mark with knowledge of the prior user, where the goods or services are identical or closely related or where the coexistence would, in practical terms, require consumers to make distinctions that the market evidence suggests they cannot make.

Essential Elements of a Coexistence Agreement – The Drafting Architecture

A trademark coexistence agreement must be drafted with the precision of a commercial contract and the legal literacy of an IP specialist. Generic drafting is not only commercially inadequate it is legally dangerous, because an ambiguously drafted coexistence agreement may fail to achieve registration at the Trademark Registry, may be disregarded by a court in subsequent litigation or may create new disputes more contentious than the one it was meant to resolve.

The identification of the marks is the agreement’s foundation. Each mark must be described with absolute precision: the exact word elements, the device or logo as reproduced, the colour scheme as registered or as used, the trademark class or classes in respect of which the mark is registered or used and the goods or services within those classes. Where the coexistence is predicated on a visual distinction between the marks a difference in stylisation, font or device element that distinction must be described with specificity sufficient to serve as an objective standard for compliance.

The scope of permitted use is the agreement’s central operative provision. This encompasses the trademark classes in which each party may use its mark, the specific goods or services within those classes, the geographic territory in which each party’s use is sanctioned, the distribution channels through which the goods or services may be offered and any branding parameters such as minimum font size, required accompanying taglines or colour restrictions designed to prevent the marks from appearing to consumers in a manner that blurs the distinction between them. Geographic division of markets allows each company exclusive use of the mark in specific regions, countries or territories and this works well for businesses with strong regional identities or limited expansion plans. Where one or both parties anticipate business expansion into new product categories, new territories or new distribution channels the agreement must address this explicitly, either by establishing a mechanism for the parties to negotiate an extension of the coexistence scope or by specifying that expansion beyond the defined scope constitutes a breach.

The obligation of non-confusion maintenance is a provision that many agreements inadequately address and that courts and the Registry treat as the agreement’s most important substantive commitment. Each party must agree to take active steps to preserve consumer clarity: to maintain agreed visual distinctions between the marks, to avoid marketing communications that blur the distinction and to cooperate in responding to instances of actual consumer confusion that may come to either party’s attention. The agreement should also contain a provision for periodic review particularly relevant where the parties operate in markets that are converging over time, as the rise of e-commerce has demonstrated by eroding territorial and channel-based distinctions that were once stable.

Procedural provisions relating to the Trademark Registry are non-negotiable elements of any coexistence agreement intended to resolve a registration conflict. The agreement must include or be accompanied by letters of consent from the senior party directed to the Trademark Registry, consenting to the registration of the junior party’s mark in the specified classes and within the specified terms. Letters of consent for pending applications must be included, as must a stipulation of registered user arrangements under Sections 48 and 49 of the Trade Marks Act, 1999, which causes the agreement’s potency to increase significantly against third parties by providing the foundation of registration. Where a pending opposition is to be withdrawn as part of the coexistence arrangement, the agreement must specify the timeline and mechanism for withdrawal and should make the withdrawal conditional on the junior party’s compliance with the agreed use restrictions.

The joint enforcement provisions deserve more attention than they typically receive in Indian coexistence drafting. Both parties share a common interest in maintaining the integrity of their respective marks against third-party infringement a coexistence arrangement diminishes neither party’s right to enforce its trademark against the world at large. The agreement should specify mutual notification obligations where either party becomes aware of third-party use that infringes or dilutes either mark and should provide a cooperation mechanism for joint enforcement action where the third-party’s conduct threatens both parties’ marks simultaneously. The sharing of enforcement costs in joint actions is a practical provision that removes an otherwise significant friction point.

The dispute resolution clause governs the management of disagreements between the parties about the interpretation or performance of the agreement itself. Pre-litigation mediation obligations, arbitration under the Arbitration and Conciliation Act, 1996, a jurisdiction clause specifying the appropriate High Court and a choice of law clause designating Indian law are standard provisions. Given the speed advantages of arbitration over court litigation in commercial disputes and the technical complexity of trademark coexistence questions, a well-drafted arbitration clause with provision for expert determination on specific technical trademark questions is often preferable to a bare jurisdiction clause.

The Letter of Consent – Its Function, its Limits and its Drafting

The letter of consent sometimes treated as a standalone instrument rather than as an appendage to a fuller coexistence agreement deserves separate analytical attention. Under Section 11(10) of the Trade Marks Act, 1999, the Registrar shall not refuse registration under Section 11(1) if the proprietor of the earlier trademark consents. In practice, the Trademark Registry accepts letters of consent as a basis for allowing applications that would otherwise face refusal on relative grounds, provided the consent is specific, unconditional within its terms and accompanied by evidence that the marks can coexist without consumer confusion.

The letter of consent is not a blank licence. A well-drafted consent letter specifies the mark in respect of which consent is given, the class or classes and the specific goods or services, any conditions on the form in which the consented mark may be used and a statement that the consenting party does not anticipate consumer confusion arising from the coexistence. Where the consent is conditional for instance, requiring the beneficiary to adopt a specific distinguishing element those conditions should be replicated in the full coexistence agreement signed between the parties, since the letter alone does not create a contractual obligation on the beneficiary to maintain compliance.

A letter of consent cannot override the public interest. As held by the apex court, while an authority permits the grant of concurrent registrations of identical or similar trademarks, if the use of the latter mark is honest and concurrent, it cannot be used as a defence to a charge of infringement once a registered proprietor has established exclusive rights. This holding establishes an important boundary: a coexistence agreement and a letter of consent regulate the relationship between the consenting parties, but they do not bind the court in a subsequent infringement action where the consenting party’s rights are being asserted against a different form of use than that covered by the consent or where market conditions have changed so materially that the original basis for coexistence no longer holds.

Competition Law Dimensions – Where Coexistence Meets the Competition Act

The intersection of trademark coexistence agreements and competition law is an area of growing practical importance in India that the profession has not yet engaged with the systematic rigour it deserves. The Competition Act, 2002, under Section 3, prohibits agreements between enterprises that have or are likely to have an appreciable adverse effect on competition. Section 3(5) of the Act provides a carve-out for intellectual property rights, stating that nothing in Section 3 shall restrict the right of any person to restrain any infringement of or to impose reasonable conditions as may be necessary for protecting any of his rights which have been or may be conferred under various IP statutes. This carve-out is critically important: it means that a coexistence agreement whose restrictions are genuinely necessary to protect the trademark rights of the parties territorial allocation, class restrictions, visual differentiation requirements falls within the protected zone.

The risk arises where coexistence agreement provisions go beyond what is necessary for trademark protection and begin to function as mechanisms for market allocation. A provision purporting to allocate customers, fix prices or coordinate competitive behaviour under the cover of trademark protection is not sheltered by Section 3(5) and falls squarely within the Competition Commission of India’s jurisdiction. Practitioners drafting coexistence agreements for parties operating in the same or adjacent markets must assess each restriction on its trademark protection merits: the tighter the geographic or class-based restriction is to the actual zone of potential consumer confusion, the more defensible it is under competition law; the further the restriction extends beyond that zone into pure market allocation, the more exposed it becomes.

International Dimensions – TRIPS, Paris Convention and Cross-Border Coexistence

Where a coexistence agreement involves a foreign trademark owner as a large number of them do, given India’s position as both an inbound destination for international brands and an outbound market for Indian brands expanding globally additional legal dimensions engage. The Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) does not mandate any particular outcome on concurrent use, but its overarching obligation that trademark protection enable the owner to prevent consumer confusion provides the international policy context within which national coexistence doctrines operate. An Indian coexistence agreement that genuinely prevents consumer confusion satisfies India’s TRIPS obligations; one that merely papers over an existing confusion risk does not.

The Paris Convention for the Protection of Industrial Property, to which India adheres by virtue of Section 154 of the Trade Marks Act, 1999, creates an international priority framework relevant to cross-border coexistence situations. Where a foreign party’s mark enjoys priority under the Paris Convention, the Indian coexistence arrangement must acknowledge that priority and structure the domestic party’s rights accordingly. In practice, this typically means the domestic party accepts class-based or territorial restrictions that reflect the international senior user’s superior claim, while the international party accepts the commercial reality of the domestic party’s established prior use in the Indian market.

The post-split use of the “Tata” name across different business areas, following the separation of the Tata Group and Tata Oil Mills (which later became part of Hindustan Unilever), exemplifies the practical operation of well-framed coexistence arrangements in the Indian context. The arrangements contain specific criteria for visual presentation and limitations on product categories that serve to safeguard against consumer confusion, notwithstanding the fame of the marks. The Tata example illustrates that coexistence is entirely viable even for marks of the highest commercial significance, provided the structural conditions genuinely distinct product categories, different consumer contexts and specific visual and presentation disciplines are scrupulously maintained.

Similarly, in Raymond Ltd. v. Raymond Pharmaceutical Pvt. Ltd., both parties decided not to engage in lengthy litigation and instead executed a coexistence agreement allowing the pharmaceutical company to use “Raymond” exclusively in medicines, while recognising the superior rights of the textile company in the broader commercial context. The Raymond arrangement demonstrates the practical wisdom of acknowledging an acknowledged senior user’s superior rights explicitly within the agreement a measure that forecloses subsequent disputes about the hierarchy of rights while still permitting both parties to operate commercially.

Enforceability Before the Registry and Courts – The Practical Position

Coexistence agreements are legally binding private contracts enforceable in Indian courts, provided they are properly drafted and executed. Before the Trademark Registry, a coexistence agreement submitted in support of a registration application or in response to a relative grounds objection carries substantial persuasive weight, particularly where the agreement demonstrates that the parties themselves who are best placed to assess market conditions have concluded that no confusion risk exists. The Himalaya Drug Company decision of the IPAB established this as a matter of adjudicative principle: the parties’ own market assessment, as expressed in a coexistence agreement, is evidence to be weighed alongside other evidence of confusion likelihood.

Before courts, the enforceability of the agreement as a private contract is governed by the Indian Contract Act, 1872. The agreement must satisfy the standard requirements of a valid contract: offer, acceptance, consideration, free consent and lawful object. The object of a coexistence agreement the orderly parallel use of similar marks under conditions designed to prevent consumer confusion is unquestionably lawful and consistent with public policy. Courts have consistently given effect to settlement agreements and consent orders in trademark matters and there is no reason in principle why a pre-dispute coexistence agreement should receive less deference, provided its terms are clear and its conditions are being observed.

The agreement’s limitation is that it binds only the parties to it. A third party who is not a party to the coexistence arrangement a sub-licensee, a franchisee or an entirely unrelated competitor is not bound by its terms and may use a mark that resembles either party’s mark without being constrained by the agreement. This is a structural limitation that the parties must address through broader registration strategy: the coexistence agreement should be accompanied by and not treated as a substitute for, comprehensive registration of all protectable elements of both parties’ marks across all relevant classes and territories.

Conclusion

Trademark coexistence agreements represent one of the most practically significant yet analytically underdeveloped instruments in Indian IP practice. The statutory framework Section 12 providing the registration basis, Section 11(10) enabling consent-based registration and the Indian Contract Act governing enforceability is adequate to support a well-structured coexistence arrangement, but it places the full burden of legal design on the parties and their advisers. The absence of dedicated legislative guidance on coexistence agreement drafting standards, on the conditions under which the Trademark Registry must accept letters of consent and on the relationship between coexistence agreements and subsequent infringement actions creates a landscape where the quality of the agreement itself is the primary determinant of its efficacy.

The judicial trajectory on coexistence in India is broadly constructive. From the Delhi High Court’s active management approach in Goenka to the IPAB’s deference to party-assessed market conditions in Himalaya Drug Company, courts and quasi-judicial bodies have demonstrated a willingness to give effect to negotiated coexistence arrangements where the structural conditions class separation, territorial delimitation, visual distinction and genuine consumer non-confusion are present and documented. The Raymond and Tata examples from commercial practice demonstrate that coexistence is a commercially viable long-term solution even for marks of the highest commercial value.

Going forward, the increasing convergence of markets through e-commerce platforms and digital distribution will test the durability of coexistence arrangements built on territorial or channel-based separation. An agreement that allocated territories or distribution channels with stability in 2010 may no longer adequately partition the commercial space in 2026. Practitioners who draft coexistence agreements for Indian clients must build in review mechanisms, change-of-circumstance provisions and technology-neutral formulations that anticipate a market environment where the traditional structural conditions for coexistence are under continuous pressure. The agreement that endures is the one that was drafted not for today’s market, but for the one the parties will operate in a decade from now.
