Case
G.R. No. 143993
Decision Date
Aug 18, 2004
McDonald's sued L.C. Big Mak Burger for trademark infringement over "Big Mak," alleging confusion with "Big Mac." Courts ruled no infringement or unfair competition, awarding damages to Big Mak.

Case Summary (G.R. No. 215994)

Factual Background

Petitioners own and extensively advertise the “Big Mac” trademark for hamburger sandwiches. Respondents, operating snack vans and outlets, adopted “Big Maka” for hamburgers and sought its registration. After receiving no response to opposition and cease‐and‐desist demands, petitioners obtained a TRO and preliminary injunction from the RTC. Respondents counterclaimed but failed to secure registration.

Trial Court’s Findings

The RTC held:

  1. “Big Mac” is a valid, distinctive, registered mark entitled to protection.
  2. Use of “Big Maka” on identical products (hamburgers) created likelihood of consumer confusion.
  3. Respondents’ adoption of “Big Maka” constituted unfair competition under Section 29 of RA 166.
  4. Permanent injunction issued; P400,000 actual, P100,000 exemplary damages, and P100,000 attorney’s fees awarded.

Court of Appeals’ Ruling

The appellate court reversed the RTC, concluding:

  • No colorable imitation exists because respondents’ “Big Maka” is part of a broader corporate name, used on varied menu items, displayed in different lettering and packaging, and accompanied by a distinct mascot.
  • No unfair competition: similarity in sound alone insufficient absent bad faith; respondents credibly derived “Maka” from founders’ names.
  • Awarded respondents P1.6 million actual and P300,000 moral damages against petitioners.

Issues Presented

  1. Whether questions of fact and law in the petition are reviewable under Rule 45.
  2. Whether respondents used “Big Maka” merely as corporate name or also as trademark on hamburgers.
  3. Whether that use constitutes trademark infringement (likelihood of confusion) and unfair competition.

Proper Basis for Review

Despite mixed factual and legal issues, the Supreme Court accepted the petition due to conflicting findings between RTC and Court of Appeals, invoking an exception to Rule 45’s restriction on questions of fact.

Use of “Big Maka” as Trademark

Evidence at injunction hearings showed respondents’ plastic wrappers and invoices bore “Big Mak” prominently, with descriptive terms in smaller type and no corporate identifier. Snack vans displayed the full corporate name, but primary product packaging highlighted “Big Mak” alone.

Trademark Infringement Analysis

Under Section 22 of RA 166, infringement requires a valid mark, registrant’s ownership, and a use likely to cause confusion as to product source or identity.

Validity and Ownership

  • “Big Mac” is a fanciful, arbitrary mark—highly distinctive and registrable under Section 4.
  • Registrant’s ownership is prima facie established; prior registrations by third parties were either assigned to McDonald’s or on the Supplemental Register (no substantive protection).

Types of Confusion

  • Confusion of goods (identical products) and confusion of business (related services) both apply because respondents sold hamburgers under “Big Maka,” the same product line.

Likelihood of Confusion
Applying the dominancy test (focusing on dominant, distinctive features):

  • Aural identity: “Big Maka” and “Big Mac” are phonetically identical in English and Filipino.
  • Visual similarity: identical first word, same initial letters in second word, nearly identical overall structure.
  • Context of use: same product, market, and consumer base.
  • Intent inferred: respondents’ implausible origin story for “Maka” suggests deliberate imitation to capitalize on McDonald’s goodwill.
  • Actual confusion need not be proved; likelihood suffices.

Conclusion: Respondents’ use of “Big Maka” infringed the “Big Mac” trademark.
