G.R. No. 131522 . July 19, 1999.
PACITA I. HABANA, ALICIA L. CINCO and JOVITA N. FERNANDO, petitioners, vs. FELICIDAD C. ROBLES and GOODWILL TRADING CO., INC., respondents.

FACTS

Petitioners, co-authors of the textbooks “College English for Today” (CET), filed a complaint for copyright infringement and unfair competition against respondent Robles, author of “Developing English Proficiency” (DEP), and its publisher Goodwill Trading Co., Inc. Petitioners alleged that DEP exhibited an uncanny resemblance to CET in content, sequence, presentation, and examples, constituting plagiarism accomplished without their authority. They prayed for the destruction of infringing copies, an accounting of profits, and an award of damages. Respondents countered that DEP was a product of Robles’s independent research and teaching experience, and any similarities stemmed from the use of common sources, general ideas, and a standard syllabus recommended by the Association of Philippine Colleges of Arts and Sciences, which are not copyrightable. They invoked the right to fair use. The trial court dismissed the complaint, finding no infringement, a decision affirmed by the Court of Appeals.

ISSUE

Whether the Court of Appeals erred in affirming the trial court’s dismissal of the complaint for copyright infringement.

RULING

No. The dissenting opinion of Chief Justice Davide, Jr., which would sustain the lower courts, provides the legal logic. Copyright protection extends only to the original expression of ideas, not to the ideas, procedures, systems, or concepts themselves. The factual findings of the trial court, affirmed by the Court of Appeals, established that the similarities between CET and DEP pertained largely to uncopyrightable elements such as the sequence of topics dictated by a common syllabus, general teaching methodologies, principles of grammar, and ideas drawn from shared sources in the public domain. The doctrine of merger applies where the idea and its expression are inseparable, such that protecting the expression would confer a monopoly on the idea itself. Here, the expression of fundamental English grammar concepts is necessarily constrained by the standard rules of the language and pedagogical conventions. Furthermore, the right to fair use allows the reasonable utilization of copyrighted materials for purposes such as teaching and research. Petitioners failed to prove that respondent Robles copied the original, protectable expression from their work, as opposed to independently arriving at similar expressions based on common knowledge and sources. The absence of proof of access to the copyrighted work or of striking and substantial similarity in protectable expression is fatal to an infringement claim. The lower courts correctly held that petitioners did not discharge their burden of proof.
