Trademark Registration Is Not Absolute Immunity: Legal Lessons from Dike Geo Motors Ltd. v. Allied Signal Inc.

CONTRIBUTOR: OKOSA CHINWENDU MARYCYNTHIA

Introduction

Trademark law plays a central role in the modern commercial and legal landscape by safeguarding the identity, reputation and goodwill of traders and businesses.^[2] In Nigeria, trademark registration is governed by the Trade Marks Act,^[3] under which the registration of a mark grants the proprietor an exclusive right to use that mark in relation to specified goods or services and to take legal action against unauthorised use.^[4] While registration confers valuable statutory rights such as the right to recover damages for the infringement of that trademark,^[5] it does not operate in isolation from broader legal principles. Indeed, Nigerian law recognises that both registered and unregistered marks can attract protection where there is potential for public confusion or deception, with unregistered marks enforceable through common-law actions such as passing off.

A prevalent misconception among practitioners and brand owners is that securing a trademark registration immunises the proprietor from all legal challenges, including allegations of infringement or passing-off.^[6] In reality, registration is but one component of a comprehensive intellectual property strategy. Additionally, statutory rights interact with equitable and common-law doctrines that prioritise marketplace fairness and consumer protection. As such, a deeper exploration of the scope and limitations of trademark protection under Nigerian law is essential to understanding how enforcement mechanisms function in practice.

Facts of the Case

The dispute arose between two companies operating in the Nigerian automotive fluids market. Allied Signal Inc., a United States-based corporation, and its French affiliate, Allied Signal Aftermarket Europe, owned a portfolio of trademarks such as “Allied and Device”, “Bendix and Device”, “DBA with Parallel Lines Design” and “e5”, under which they marketed brake and clutch hydraulic fluids in Nigeria, with distinctive black, red and white packaging that had become familiar to consumers.

Dike Geo Motors Ltd., a Nigerian company, conducted business in the same sector, offering brake and clutch fluids branded simply as “Allied”. These products closely resembled the respondents’ goods in both mark and packaging, leading to alleged confusion in the marketplace. Acting through its chief executive officer, Dike Geo began selling these products in the early 1990s. The respondents commenced proceedings at the Federal High Court, Lagos, asserting claims of trademark infringement and passing off based on the similarity of marks and presentation. The Appellants primarily contended that they were not responsible for manufacturing the products alleged to infringe the Respondents’ rights. Their position was that they merely distributed the products, which they sourced from Don Frank Nigeria Limited (DFNL), the entity they identified as the actual manufacturer. While the action was pending, DFNL sought registration of the trademark “Allied and Device” in Class 4. Although the Respondents challenged this application, the mark was subsequently registered. In light of this development, the Appellants brought a motion on notice requesting the dismissal of the suit on the basis that it had become frivolous and an abuse of judicial process. The trial court considered the application but declined to grant it. Dissatisfied with that ruling, the Appellants pursued an appeal to the Court of Appeal and subsequently to the Supreme Court, both of which were unsuccessful.

Before the Supreme Court, the Appellants maintained that no reasonable cause of action lay against them, arguing that the trademark in dispute had been validly registered in the name of DFNL under Class 4. They further stressed that the Respondents had actively participated in the opposition proceedings that preceded the eventual registration of the mark “Allied and Device” in favour of DFNL. The Appellants contended that a claim for trademark infringement presupposes the absence of legal entitlement to the mark on the part of the alleged infringer. Consequently, where a defendant holds a valid legal right, the proper course is to seek registration, during which period any infringement proceedings ought to be stayed. Relying on sections 5, 6, and 20 of the Trademarks Act, Cap. 436, Laws of the Federation of Nigeria (LFN) 1990, the Appellants argued that the Act does not envisage the concurrent existence of infringement proceedings and registration processes concerning the same trademark. On this basis, they submitted that the Respondents’ claims were untenable.

In relation to the claim for passing off, the Appellants, relying on Ayman v. Akuma Enterprises,^[7] argued that the Federal High Court lacked jurisdiction to entertain the claim, on the ground that such jurisdiction is limited to passing-off actions arising from registered trademarks, and does not extend to actions for passing off simpliciter involving unregistered marks.

The Respondents, on their part, contended that the registration of the mark “Allied and Device” did not constitute a complete defence to their claims. They maintained that their action before the lower court concerned infringement and passing off in respect of a trademark registered in Class 1, and not Class 4. They argued further that the claim for passing off remained sustainable, as trademark registration does not confer a right to deceive or mislead consumers. The Respondents also submitted that registration is not an absolute bar to an infringement action, particularly where the registered mark is capable of causing confusion or deception in the marketplace.

Supreme Court’s Decision

In determining whether the subsequent registration of the mark “Allied and Device” by the Appellants extinguished the Respondents’ claims, the Supreme Court held firmly that trademark registration does not invariably constitute a complete defence to actions for infringement or passing off. The Court reasoned that since the Respondents had already been using the mark in the course of trade, the later registration by the Appellants could not, by itself, defeat the pending claims. In reaching this conclusion, the Court relied on the decisions in N.R. Dongre v. Whirlpool Corporation and Eli Lilly & Co. Ltd. v. Chelsea Drug Chemical Co. Ltd.

The Court further observed that an aggrieved party retains several remedies even after trademark registration, including rectification proceedings under section 38 of the Trademarks Act, an appeal to the Federal High Court under section 56(b), or the institution of an infringement action. It held that the Respondents had validly elected to pursue an infringement claim, which remained maintainable notwithstanding the registration. Accordingly, the Appellants’ argument that the Respondents’ action had abated was rejected.

On the issue of passing off, the Court reiterated that the doctrine is aimed at preventing deception and that trademark registration does not entitle its holder to mislead the public. After examining section 7 of the Federal High Court Act, as amended, the Supreme Court affirmed that the Federal High Court has jurisdiction to entertain claims for passing off, whether arising from registered or unregistered trademarks, and consequently held that Ayman v. Akuma^[8] Enterprises was decided per incuriam. Thus, the appeal was dismissed.

Practical Implications for Trademark Practice

The Supreme Court’s ruling in Dike Geo Motors Ltd. v. Allied Signal Inc.^[9] has important consequences for how trademark rights are managed and enforced in Nigeria. Firstly, it is important that trademark owners and practitioners recognize that registration alone does not guarantee immunity from infringement or passing-off claims. It confers exclusive use rights but does not justify misleading consumers. A registered mark should not be used to create confusion or to misrepresent goods as those of another, and the Nigerian courts will examine actual marketplace impact rather than rely solely on formal registration status.

It is also vital that clients that brand enforcement must include more than filing for registration. Strategies such as vigilant monitoring of the market for confusing marks, opposition and cancellation proceedings at the Trademarks Registry, and prompt litigation when consumers are likely to be misled are essential.

The decision also emphasizes that passing-off actions remain viable even where a mark is registered. This gives strong support to the value of establishing goodwill and distinctiveness through use. Thus, trademark owners should actively build and document market presence to support passing-off claims where necessary.

Conclusion

In summary, the Supreme Court’s decision in Dike Geo Motors Ltd.’s case confirms that trademark registration does not automatically shield a proprietor from claims of infringement or passing off. Liability depends on whether the use of the mark is likely to mislead consumers. This shows that registration enhances rights but is not an absolute defence under Nigerian law.
