Likelihood of Confusion in the Philippines Under IP Code Section 123.1(d)-(f)

For many applicants, the greatest registration risk in the Philippines is not descriptiveness but conflict with an earlier mark. Section 123.1(d) to (f) of the Intellectual Property Code governs the principal relative grounds for refusal, and IPOPHL applies a practical confusion analysis that looks at both the marks and the goods or services. The key issue is whether ordinary Philippine consumers are likely to believe that the goods come from the same source, from economically linked sources, or from a brand family. Because businesses often compare only class numbers or side-by-side visual differences, they underestimate how strongly dominant wording, product proximity, and conceptual overlap can influence the result.

The Legal Framework: Republic Act No. 8293, Section 123.1(d), (e), (f) and Section 159.1

• Section 123.1(d): Refuses a mark that is identical with a registered mark belonging to a different proprietor or a mark with an earlier filing or priority date in respect of the same goods or services, closely related goods or services, or goods or services so resembling as likely to deceive or cause confusion.
• Section 123.1(e): Refuses marks identical with, or confusingly similar to, a mark considered by the competent authority to be well known internationally and in the Philippines, whether or not registered in the Philippines, for identical or similar goods or services.
• Section 123.1(f): Extends protection to well-known marks even for dissimilar goods or services where use of the mark would indicate a connection and likely damage the owner of the well-known mark.
• Section 159.1: Preserves the rights of a good-faith prior user as a defense in infringement matters, underscoring that registration is not the entire story in relative-rights disputes.
• Section 134: Opposition may be brought on the basis of these relative grounds after publication.

The Likelihood-of-Confusion Test

The Philippine test is a likelihood-of-confusion inquiry. IPOPHL does not require proof of actual confusion. The question is whether the relevant consumers, using ordinary care appropriate to the goods or services, would likely be deceived or confused as to source, sponsorship, affiliation, or business connection.

Although the statute does not set out a rigid multi-factor formula, Philippine practice consistently focuses on two pillars: similarity of the marks and similarity or relatedness of the goods or services. When both are high, refusal is likely. When one is weak, the result depends on the strength of the other and on the overall impression of the marks.

For well-known marks under Section 123.1(e) and (f), the protection expands. Identical or confusingly similar marks can be refused even without Philippine registration by the earlier owner, and even on dissimilar goods where a misleading connection and likely damage can be shown.

What IPOPHL Considers in a Confusion Analysis

Visual, phonetic and conceptual similarity

IPOPHL compares marks as a whole, but not mechanically. It considers their appearance, sound, and meaning.

• Visual similarity: Shared beginnings, distinctive letter strings, overall structure, length, and stylization.
• Phonetic similarity: Pronunciation as understood by ordinary Philippine consumers, including likely local pronunciation of foreign words.
• Conceptual similarity: Similar meanings, associations, or translated equivalents.

No single dimension is always decisive. A strong visual match on identical goods can be enough. So can a strong conceptual match where consumers are likely to translate or understand the same idea.

Goods and services similarity

Class numbers are only the starting point. IPOPHL considers whether the goods are identical, closely related, complementary, sold through the same trade channels, or directed to the same consumers. Products in different Nice classes can still be related. Conversely, goods in the same class may in some cases be sufficiently remote that confusion is less likely.

Dominant element comparison

In combined marks, Philippine practice gives significant weight to the dominant element, often the word portion. If two composite marks share the same dominant word, differences in logos, color, or layout may not avoid confusion. If the common wording is descriptive or disclaimed, the analysis may shift toward the remaining distinctive matter, but the examiner still assesses the overall commercial impression.

Word-to-word analysis

For plain word marks, the Bureau of Trademarks typically considers whether the marks share a memorable and distinctive core. Similar prefixes, suffixes, or syllabic patterns can be important, especially if the goods are related and the shared element is not weak or descriptive.

Word-to-logo and combined-mark analysis

If a logo contains readable wording, IPOPHL often compares that wording directly to a cited word mark. A stylized logo can still conflict with a plain word registration if consumers will call for the goods by the wording. Conversely, a purely figurative mark with no readable verbal content is less likely to conflict with a word mark unless the design itself has become strongly associated with a particular source.

Well-known marks

For Section 123.1(e) and (f), IPOPHL assesses fame, recognition, and the likelihood that consumers will assume a connection. This can produce refusal even where the goods differ or where the earlier owner has not secured a Philippine registration in the same class.

Multilingual considerations

The Philippines is linguistically diverse. Examiners may consider translation, transliteration, and pronunciation across English, Filipino, Spanish, and other languages where the relevant public would perceive similarity. Conceptual overlap can be important when one mark is the foreign-language equivalent of another.

Key Case Law

• Kolin Electronics Co., Inc. v. Kolin Philippines International, Inc. [2021] — The Supreme Court examined confusion between similar marks used on related electronic goods. The case confirms that goods need not be identical if they are sufficiently related that consumers may assume common origin.
• Societe Des Produits Nestle, S.A. v. Court of Appeals and CFC Corporation [2001] — The Court discussed the dominance of the shared term “MASTER” in coffee-related marks, illustrating how a common dominant component can drive confusion analysis.
• Lim v. See [2023] — Although not a standard Section 123.1(d) examination case, it reinforces that a first filer cannot rely on formal priority where the filing itself appropriates another party’s brand in bad faith.

The Procedure for Responding to a Relative-Ground Refusal

Step 1: Analyze the cited mark and goods carefully

Do not assume that a citation is fatal simply because the marks look similar. Compare the exact goods, the nature of the shared element, and whether the common matter is weak or descriptive.

Step 2: Distinguish the marks on all three dimensions

Address visual, phonetic, and conceptual differences. If one dimension strongly favors the applicant, explain why it dominates consumer perception in the Philippine market.

Step 3: Argue weakness of the common element if justified

If the shared term is descriptive, laudatory, or diluted by third-party use, show that consumers are accustomed to distinguishing among marks containing that element.

Step 4: Limit goods or services where commercially acceptable

Narrowing the specification to avoid overlap or to clarify different trade channels can be an effective response.

Step 5: Consider coexistence or consent arrangements

While not automatically binding on IPOPHL, an agreement with the owner of the cited mark may support a practical settlement or a more tailored prosecution strategy.

Step 6: Prepare for opposition even if the citation is overcome

An examiner may withdraw a citation while the earlier owner still opposes after publication. The legal theory and evidence should therefore be developed with both stages in mind.

Strategic Recommendations

• Recommendation: Conduct full clearance searching beyond identical marks and beyond identical classes, focusing on related goods and dominant wording.
• Recommendation: Give extra weight to the first and dominant word in a proposed mark, because that is often what consumers remember and what IPOPHL emphasizes.
• Recommendation: Avoid marks that rely on a crowded industry term plus a minor modifier, especially in consumer goods sectors.
• Recommendation: For composite marks, assess whether the logo adds real distinction or merely decorates otherwise conflicting wording.
• Recommendation: Screen for well-known international brands even where no obvious local registration appears in the same class.

Common Mistakes

• Mistake: Assuming different Nice classes eliminate confusion risk.
• Mistake: Focusing only on side-by-side visual differences and ignoring how the marks sound or what they mean.
• Mistake: Overestimating the legal value of stylization where the same dominant wording appears in both marks.
• Mistake: Ignoring third-party opposition risk after an examiner citation has been overcome.
• Mistake: Underestimating the reach of well-known mark protection under Section 123.1(e) and (f).

Key takeaway: Under Section 123.1(d) to (f), the Philippine confusion analysis is holistic but practical: similarity of marks, relatedness of goods, and the dominant source-identifying element usually determine the outcome. Clearance should therefore be broader than class matching and deeper than simple visual comparison.
