Case Summary (G.R. No. 143993)

Key Dates

McDonald’s introduced the Big Mac in the Philippines in September 1981 and secured Philippine registration of the BIG MAC mark on 18 July 1985 (based on a U.S. registration from 16 October 1979). Respondent L.C. Big Mak Burger, Inc. applied to register “BIG MAKA” on 21 October 1988. Petitioners filed suit on 6 June 1990; the RTC issued a TRO on 11 July 1990 and a preliminary injunction on 16 August 1990. The RTC rendered judgment for petitioners on 5 September 1994. The Court of Appeals reversed on 26 November 1999; its denial of reconsideration was entered 11 July 2000. The Supreme Court decision under review was rendered in 2004.

Applicable Law and Constitutional Basis

Primary substantive law applied: Republic Act No. 166 (the Trademark Law as amended) — specifically Sections 22 (infringement), 23 (remedies), and 29 (unfair competition) — with reference to its successors and the Intellectual Property Code (RA 8293). Procedural basis for the petition: Rule 45 of the Rules of Court (petition for review on certiorari raising questions of law). Because the decision date is after 1990, the 1987 Philippine Constitution is the governing constitutional framework for judicial review and exercise of appellate jurisdiction.

Facts Relevant to the Claim

McDonald’s owns and extensively uses the BIG MAC mark for its double-decker hamburger and other branded items; it invested substantial advertising and used the mark on packaging, paraphernalia, and signages. Respondents operated snack vans and outlets selling hamburgers and other foods and used the name/mark “Big Mak/Big Maka” on wrappers and in corporate identification. Petitioners opposed respondents’ trademark application and sent a demand to desist; respondents did not respond, leading to the 1990 suit alleging trademark infringement and unfair competition.

RTC Judgment and Rationale

The Regional Trial Court (Makati, Branch 137) found respondent corporation liable for trademark infringement and unfair competition, made the preliminary injunction permanent, and awarded actual, exemplary damages and attorney’s fees to petitioners while dismissing claims against the individual respondents and respondents’ counterclaims. The RTC reasoned that despite some physical distinctions in packaging and presentation, the use of BIG MAKA by respondents on hamburgers was likely to confuse ordinary consumers and constituted an attempt to appropriate the goodwill and reputation of McDonald’s BIG MAC.

Court of Appeals Ruling and Rationale

The Court of Appeals reversed the RTC. It treated respondents’ use primarily as a corporate or trade name rather than an exclusive product trademark and applied a holistic test comparing overall presentation, packaging, and market circumstances. The CA emphasized differences in packaging material, presence of other wording and mascots, diversified product lines, and different market channels (snack vans versus McDonald’s restaurants) to conclude there was no colorable imitation, no sufficient evidence of bad faith, and therefore no unfair competition.

Issues Presented to the Supreme Court

Procedural: whether Rule 45 was properly invoked (the petition raised questions of law, with conflicting factual findings between RTC and CA). Substantive: (1) whether respondents used BIG MAKA as a trademark for their hamburger products (not merely as part of a corporate name); (2) whether respondents are liable for trademark infringement and unfair competition under RA 166.

Jurisdictional/Procedural Disposition

The Supreme Court recognized that Rule 45 ordinarily allows only questions of law but accepted the petition under an established exception where the trial court and the Court of Appeals reached conflicting findings of fact in a trademark/unfair competition case. The Court therefore reviewed the case on its merits.

Validity of the BIG MAC Mark and Ownership

The Court affirmed that BIG MAC is a valid, distinctive mark (fanciful/arbitrary rather than generic or merely descriptive) and that registration on the Principal Register creates a prima facie presumption of validity and ownership. Challenges based on earlier Philippine registrations by third parties failed because Topacio had assigned his rights to McDonald’s and the Isaias Group’s registration was on the Supplemental Register, which does not afford the same protection as the Principal Register.

Types of Confusion and Legal Framework

Under Section 22, infringement is established when the defendant uses a reproduction, counterfeit, copy or colorable imitation of a registered mark in connection with goods or services such that confusion or mistake as to source or origin is likely. The Court distinguished two types of confusion: confusion of goods (product confusion where consumers buy one product believing it to be another) and confusion of business (source/affiliation confusion where non-competing but related products suggest a connection). RA 166 (and subsequent jurisprudence) extends protection beyond identical goods to related goods and source confusion.

Applicable Test for Likelihood of Confusion

The Court explained two jurisprudential approaches: the holistic test (examining overall presentation, packaging, and context) and the dominancy test (focusing on dominant or essential features of the marks and their aural, visual and connotative impressions). The Supreme Court reaffirmed its preference for the dominancy test and noted that the doctrine is reflected in later statutory formulations treating infringement as reproduction of a registered mark or a dominant feature thereof.

Application of the Dominancy Test to Facts

Applying the dominancy test, the Court found that BIG MAKA is dominantly similar to BIG MAC: aurally they are effectively identical (idem sonans), the first word is identical, and the second word shares key letters and sounds such that ordinary purchasers cannot distinguish them by sound and may not differentiate them visually in ordinary commercial encounters. The Court gave weight to the aural and visual impressions and to McDonald’s established reputation and advertising, concluding respondents adopted the dominant features of the BIG MAC mark and thereby created a likelihood of confusion when used on the same product—hamburgers.

On Respondents’ Claimed Good Faith and Explanations

The Court rejected respondents’ proffered explanation that the word “Maka” derived from familial names as not credible in context. The timing, the similarity to McDonald’s mark, and the absence of convincing proof of an honest, independent origin supported an inference
