Likelihood of Confusion in Bangladesh Under Section 10: Relative Grounds and Dominant Elements

Relative grounds are central to trademark clearance and prosecution in Bangladesh because even a distinctive and lawful mark can be refused if it conflicts with earlier rights. Section 10 of the Trademarks Act, 2009 is the key provision, and its practical focus is likelihood of confusion. For businesses, the question is not only whether two marks are identical, but whether consumers would likely assume a commercial connection because of similarities in wording, appearance, sound, meaning, or the goods and services involved. The Department of Patents, Designs and Trademarks applies this analysis in a pragmatic way, often giving substantial weight to the dominant element of a combined mark and to the commercial relatedness of the goods or services.

The Legal Framework: Section 10 and Related Provisions

• Section 10(1): Bars registration of a mark that is identical with or deceptively similar to an earlier registered trademark of another person for the same goods or services or description of goods or services.
• Section 10(2): Allows the Registrar to permit registration in cases of honest concurrent use or other special circumstances, subject to conditions and limitations.
• Section 10(4)-(5): Extends protection to well-known marks and prevents registration that would create a false connection with another enterprise even outside identical goods situations.
• Section 8(c): Also bars marks likely to deceive or cause confusion, which may overlap with relative-ground analysis in some cases.
• Section 18: Allows any person in Bangladesh to oppose an accepted mark, often on Section 10 grounds.
• Section 100: Provides appeal rights from Registrar decisions to the High Court Division.

The Likelihood of Confusion Test Under Section 10

The statutory language of Section 10 centers on marks that are identical or deceptively similar. In practical terms, the DPDT uses a likelihood of confusion analysis. Actual confusion need not be proved. The question is prospective: would the average consumer of the relevant goods or services likely be misled into thinking that the goods or services come from the same undertaking or from economically linked undertakings?

Although the Act does not enumerate a formal multi-factor test, several factors routinely matter:

• Similarity of the marks: visually, phonetically and conceptually.
• Similarity of the goods or services: whether they are identical, similar, complementary or commercially related.
• Distinctiveness of the earlier mark: stronger earlier marks usually enjoy broader protection.
• Dominant and memorable elements: especially in combined marks.
• Consumer perception: from the standpoint of the average purchaser in the relevant trade context.

The Registrar is not required to find exact copying. If the overall resemblance is sufficient to create deception or confusion in trade, Section 10 can apply.

What the Department of Patents, Designs and Trademarks Considers in Relative Grounds Analysis

The DPDT generally compares marks in totality, but in practice often gives extra weight to the dominant element. This is especially important where one or both marks combine words and devices.

Visual similarity

Visual similarity concerns how the marks look. Examiners will compare spelling, structure, length, shared prefixes or suffixes, layout and overall impression. Small differences in letters may not be enough if the marks still look close in ordinary trade conditions. This is particularly relevant for consumer goods sold quickly or purchased by imperfect recollection.

Phonetic similarity

Phonetic similarity concerns how the marks sound when spoken. In Bangladesh, this can become complicated where marks are in English but pronounced through Bengali speech patterns, or where foreign words are transliterated. Homophones, near-homophones and rhythmically similar marks can be problematic even if visually different. For example, minor spelling differences may not avoid confusion if consumers pronounce the marks in substantially the same way.

Conceptual similarity

Conceptual similarity concerns meaning. Two marks may be conceptually close if they evoke the same idea, object, quality or source association, even if their exact wording differs. This can include cross-language similarity. A Bengali word and an English word may be conceptually similar if they communicate the same idea to the relevant public.

Goods and services similarity

Similarity of goods or services is not limited to Nice class identity. The DPDT looks to commercial reality: whether the goods are the same, similar, complementary, substitutable, sold through the same channels, aimed at the same public, or likely to be perceived as originating from the same undertaking. Goods in different classes can still be related. Conversely, marks that are similar may coexist more easily if the goods or services are genuinely unrelated.

Dominant element in combined marks

The dominant-element doctrine is especially important in Bangladesh practice. If the word component is the portion consumers are most likely to remember, pronounce and use, the DPDT will often treat it as dominant. A combined mark containing a weak device and a highly similar word may therefore conflict with an earlier word mark. Conversely, where a device is genuinely distinctive and the wording is minor or non-distinctive, the device may have more weight.

Applicants should therefore compare marks not only as artistic compositions but as market signs. If a combined mark will be called for orally by its word element, that word often drives the confusion analysis.

Well-known marks

Section 10 also protects well-known marks against false connection, even where the goods are not identical. This means applicants should not assume safety simply because the specification is in a different class. If the earlier mark is well known, the scope of protection may be broader.

Key Case Law

• Danish Foods Ltd. v. Registrar [2013] — relevant as a Section 100 appeal in a registry dispute, illustrating that DPDT conflict decisions can be scrutinized by the High Court Division.
• Popular Polish House Ltd. v. Trade Marks Registry 21 DLR (SC) 114 [1969] — although mainly cited for stylization and distinctiveness, it remains relevant to how overall impression and mark composition may affect registrability.

No leading modern Bangladeshi appellate cases have been published that set out a comprehensive Section 10 confusion matrix equivalent to that found in some larger jurisdictions. As a result, the statutory text and registry practice are the principal guidance.

The Procedure for Responding to a Section 10 Refusal

A Section 10 refusal requires a disciplined comparative response.

• Step 1: Identify the cited earlier mark and confirm its status, goods or services, and ownership.
• Step 2: Compare the marks visually, phonetically and conceptually. Do not rely on only one mode of comparison.
• Step 3: Assess the similarity of goods or services in commercial terms, not merely by class number.
• Step 4: For combined marks, identify the dominant element in both the applicant’s mark and the cited mark.
• Step 5: If appropriate, narrow the specification to reduce overlap.
• Step 6: Argue marketplace distinctions, differences in commercial impression, and the weakness of shared descriptive matter where relevant.
• Step 7: In exceptional cases, consider whether honest concurrent use or other special circumstances under Section 10(2) may justify coexistence.
• Step 8: File the response within the Rule 24 deadline, request a hearing if useful, and preserve appeal rights under Section 100.

If the conflict arises in opposition rather than examination, the same core analysis applies, but the parties may submit evidence, including use evidence, coexistence history, and market materials.

Strategic Recommendations

• Recommendation: Conduct Bangladesh-specific clearance before filing. Section 10 problems are easier to avoid than to cure.
• Recommendation: Compare marks by sight, sound and meaning. A mark can be refused even if it differs in only one of these dimensions.
• Recommendation: Analyze goods and services commercially, not only by Nice class. Cross-class relatedness can still create confusion risk.
• Recommendation: In combined marks, clear the dominant element first. If the word will dominate consumer perception, that is where the real risk lies.
• Recommendation: Be cautious around famous or well-known marks, even for dissimilar goods, because Section 10 extends beyond strict product identity.

Common Mistakes

• Mistake: Assuming a different logo avoids conflict where the word element is highly similar to an earlier mark.
• Mistake: Relying solely on different class numbers. Class separation does not guarantee unrelated goods or services.
• Mistake: Ignoring Bengali pronunciation of English marks. Phonetic similarity may be stronger in actual market use than on paper.
• Mistake: Comparing only the marks and not the goods. Section 10 is always a combined marks-and-goods inquiry.
• Mistake: Treating descriptive shared matter as dispositive in either direction. Shared weak matter may reduce conflict significance, but dominant distinctive matter can still drive refusal.

Key takeaway: Under Section 10, Bangladesh evaluates relative grounds through a practical likelihood-of-confusion analysis that looks at mark similarity, goods relatedness and dominant elements. Clearance should therefore focus on how consumers in the Bangladeshi market will actually perceive and remember the sign, not just on formal differences in artwork or spelling.
