The Federal High Court of Nigeria recently adjudicated on the landmark case of Sanofi S.A. v. Sanofi Integrated Services Ltd, Sanofi Nigeria Enterprises Limited, Susan Namiji (Trading under the name and style of Sanofi Nigeria Enterprise), and the Corporate Affairs Commission (CAC) – the SANOFI Trademark Case. Trademarks, central to a company’s identity, can become points of contention when similarities between entities arise. This case underscores the crucial importance of vigilance in upholding and defending a trademark’s distinctiveness. For businesses holding registered trademarks, the relevance of this case is paramount. By understanding the ramifications of this judgment, companies can proactively protect their brand identity and remain prepared for any potential legal challenges.


Sanofi S.A., headquartered in Paris, is a renowned French multinational pharmaceutical company active since 1973. Its corporate lineage includes a merger in 2004, forming Sanofi-Aventis, which rebranded to SANOFI S.A. in 2011. Demonstrating its commitment to the Nigerian market, the company registered its trademark as early as 11 February 1987 under Trademark No. 57973 SANOFI (Word and Device). Furthermore, the firm established a foothold in the Nigerian market by initiating its subsidiary, SANOFI-AVENTIS NIGERIA LIMITED, in 1999.

However, a challenge arose when SANOFI S.A. identified that the 1st – 3rd Defendants were utilising the SANOFI trademark within their company and business names. The Plaintiff’s perspective was clear: such use could misleadingly suggest a linkage or association. With a claim to the SANOFI name from 1987, the Plaintiff asserted that the Defendants’ use was unsanctioned and infringed on their established rights. The issue remained unresolved despite the Plaintiff’s attempts at resolution through cease-and-desist letters. The matter was escalated to the 4th Defendant, who, after reviewing the claims, issued a directive for the 1st – 3rd Defendants to alter their business names within six weeks. The order, however, went unheeded.

Conversely, the 1st – 3rd Defendants trace their use of the SANOFI name back to 1992 when they registered SANOFI NIGERIA ENTERPRISES. Their commitment to the name extended to 2011 with the formation of SANOFI INTEGRATED SERVICES LTD and in 2013 with SANOFI NIGERIA ENTERPRISES LIMITED. Their narrative took a twist in January 2021 upon receiving a notification that their use of “SANOFI” allegedly conflicted with the Plaintiff’s 2004 trademark. They responded with evidence of their earlier 1992 registration, challenging the Plaintiff’s 2004 claim. The Defendants also highlighted a directive from the 4th Defendant in February 2021, instructing the Plaintiff to modify its subsidiary’s name, an instruction the Plaintiff did not action.

The Legal Framework

Business operations in Nigeria take their cue from the Companies and Allied Matters Act 2020 (CAMA 2020). Among its many provisions, the Act outlines clear directives related to the naming of businesses, promoting clarity and preventing confusion.

a. Distinctiveness of Company Names:

CAMA 2020 is explicit: company names should stand apart. This means no two businesses should have identical or confusingly similar names. Such clarity in naming prevents potential misunderstandings among consumers and ensures that companies can confidently build their brand without fear of encroachment.

b. Corporate Affairs Commission’s Role:

Central to this process is the Corporate Affairs Commission (CAC). As the arbiter of company names, the CAC has the power to approve, reject, or suggest modifications. Their objective? Ensure every business has a unique identifier, free from conflicts and disputes.

Shifting focus to trademarks, these legal identifiers bear a weight of their own, going beyond mere naming to encapsulate a company’s essence and reputation.

c. Trademark as a Proprietary Right:

A trademark is more than just a name or symbol; it’s a company’s badge of honour. It signifies trust, quality, and the very identity of a brand. And because of its value, the law offers it significant protection.

d. Judicial Insights:

Trademark protection is evident in cases such as ALLIANCE INTL LTD v. SAAM KOLO INTL ENTERPRISES Ltd (2022) LPELR-57984(SC) and MORISON INDUSTRIES PLC v. CPL INDUSTRIES LTD (2021) LPELR-52981(CA). Here, the courts firmly sided with the rights of trademark holders. They held that a registered trademark grants its owner exclusive rights, and any unsanctioned use is, without doubt, an infringement.

e. Protection under the Trademarks Act:

The Trademarks Act further underpins these rights. It offers a procedure for registering trademarks and ensures they are shielded from misuse. The Act acts as a shield, ensuring that the reputation and value encapsulated within a trademark remain uncompromised.

Court’s Findings and Rationale

After examining the presented evidence and arguments, the Court arrived at several key conclusions:

  1. Timeliness of the SANOFI Trademark Registration:

The Court recognised that the SANOFI trademark owned by the Plaintiff was duly registered well before the 1st to 3rd Defendants’ adoption of their respective business names. This earlier registration grants the Plaintiff exclusive rights and specific legal protections related to using the name within its industry.

  1. Trademarks’ Priority Over Business Names:

In its determination, the Court emphasised that legally, trademarks carry more weight than business names. A trademark does not merely act as a name identifier; it signifies a business’s accrued reputation and the trust it has garnered over time. Allowing overlap, especially when a trademark has historical precedence, undermines the protective intent of trademark legislation.

  1. Alignment with Established Legal Precedents:

The Court’s findings are consistent with the ruling in VIRGIN ENTERPRISES LTD v. RICHDAY BEVERAGES (NIG) LTD. (2009) LPELR-8187(CA). This benchmark case provides valuable insights into determining trademark infringements, with a pivotal focus on potential confusion amongst the general public. Given SANOFI’s widespread recognition and established reputation, any resemblance in name by the 1st to 3rd Defendants can mislead the public, thereby constituting infringement. This situation underscores the imperative for businesses to undertake diligent name vetting to avoid clashes with pre-existing trademarks.

Accordingly, the Court upheld the Plaintiff’s rights, anchored on the prior registration of the SANOFI trademark. This ruling highlights the paramount role of trademarks in establishing and safeguarding a distinct business identity, ensuring brands can operate without undue confusion or overlap. Through this verdict, the sanctity and robust protection offered by registered trademarks have once again been reaffirmed.

Implications for Businesses

The Federal High Court’s recent ruling in the SANOFI case has shed light on several critical business considerations.

  1. Thorough Pre-Registration Checks:

The case accentuates the importance of businesses verifying the absence of similar company names and checking for pre-existing trademarks. Such a holistic approach prevents inadvertent infringements and ensures a distinct market presence for a brand.

  1. Unintentional Infringements Bring Repercussions:

A lack of awareness does not absolve a business from legal consequences. Inadvertently infringing on a registered trademark can lead to significant repercussions. Businesses may face not only rebranding costs but might also be liable to compensate the injured parties. This highlights the importance of thorough groundwork before branding.

  1. Consequences Beyond Financial Implications:

Apart from potential financial liabilities, the SANOFI case highlights other possible outcomes of trademark disputes. The Court’s directive for the defendants to modify their business names underscores the magnitude of repercussions a company might face. Rebranding can result in substantial operational costs and market repositioning challenges. Furthermore, tarnishing a brand’s image, once associated with legal battles, can be a lasting detriment.

Consequently, it is paramount for businesses to be proactive, ensuring they undertake comprehensive checks and obtain informed counsel when selecting or revising their name or brand identity. Such precautions are essential in safeguarding a company’s interests and maintaining its reputation.

Understanding Intellectual Property: Common Misconceptions and Practical Insights

Intellectual property (IP) rights are essential for many businesses. However, misconceptions about IP can lead to oversights and potential risks. Here, we address some common misunderstandings and offer practical insights:

a. IP Protection Is Automatic: Some businesses assume that once they create a unique product, logo, or slogan, it’s automatically protected. While copyright might arise automatically, trademarks, patents, and designs often require formal registration and regular renewal.

b. All IP Rights Are the Same: IP encompasses copyrights, patents, trademarks, and trade secrets. Each serves a different purpose and has distinct registration processes and protection durations. Lumping them together can lead to gaps in protection.

c. Local IP Registration Means Global Protection: Registering IP rights in one country doesn’t grant international protection. For global safeguarding, businesses might need to consider regional or international filing systems.

c. Once Registered, Protection Is Absolute: Businesses must remain vigilant even with a registered IP. It’s essential to monitor for infringements and be ready to uphold and defend one’s rights when required.

d. IP Isn’t Relevant to My Business: Every business, from tech innovators to artisanal craftsmen, produces and uses IP. Ignoring its value and applicability can leave crucial assets unprotected.

e. IP Protection is Too Expensive: While there’s a cost to register and maintain IP rights, this investment is often minor compared to the potential expenses and losses incurred from infringements or legal disputes.

For businesses keen on strengthening their IP position, it is imperative to stay informed, seek expert advice, and regularly review and update their IP strategies. This way, they remain protected and competitive.

Actionable Steps for Businesses to Protect Their Intellectual Property

Safeguarding intellectual property (IP) is a strategic imperative for businesses. Here are suggested steps to ensure your business remains on the right side of IP laws:

  1. Conduct Comprehensive Checks: Before finalising a company name, examining the company and trademark registries is essential. This proactive measure minimises the risk of legal conflicts in the future.
  1. Trademark Valuable Assets: Think beyond just the company name. Secure exclusivity for your logos, slogans, and other brand-defining elements by getting them trademarked. This not only strengthens brand identity but also deters potential infringers.
  1. Regular Renewals: Trademarks aren’t protected indefinitely. To maintain your rights and guard against violations, renew your trademarks at required intervals.
  1. Stay Updated with Legal Precedents: Legal interpretations shift over time. Businesses can adapt and mitigate potential challenges by keeping a finger on the pulse of recent IP-related court decisions.
  1. Seek Legal Advice: There’s merit in expertise. When considering a new venture, a rebrand, or periodic review, soliciting legal counsel can help pinpoint vulnerabilities or areas of concern, potentially sparing financial and reputational costs.
  1. Educate and Train: Knowledge equips and empowers. Familiarise your team with IP essentials, especially those in branding and marketing roles. An informed workforce can better sidestep infringement pitfalls and spot potential threats.

In today’s competitive market, a company’s brand is one of its most valuable assets. Ensuring its protection is a legal necessity and a cornerstone of robust business strategy.


Protecting intellectual property rights is paramount for businesses, signifying brand identity and a commitment to innovation. Overlooking or infringing on these rights can result in significant legal and financial challenges. As the landscape of commerce continues to evolve, companies need to shield their intellectual assets and equally respect the rights of others. This proactive approach ensures long-term success and credibility in the market. Companies are, therefore, encouraged to remain diligent, constantly update their knowledge, and maintain a culture that values and respects intellectual endeavours.
