Del Rosario v. Court of Appeals
REITERATIONFacts
The Antecedents: Petitioner Roberto L. del Rosario filed a complaint for patent infringement against private respondent Janito Corporation, alleging that he was the patentee of audio equipment, specifically a sing-along system or karaoke, under Letters Patent No. UM-5269 and UM-6237. He claimed that private respondent was manufacturing a substantially similar sing-along system under the trademark "miyata" or "miyata karaoke" without his consent. Procedural History: The Regional Trial Court (RTC) of Makati initially issued a temporary restraining order and subsequently a writ of preliminary injunction in favor of petitioner, finding that petitioner was a holder of a utility model patent and that private respondent was manufacturing and selling a substantially similar product without authorization. Private respondent assailed this order before the Court of Appeals (CA) via a petition for certiorari. The CA granted the writ, setting aside the RTC's order, opining that there was no patent infringement solely based on the manufacture of the "miyata karaoke" system, as karaoke systems were universal products manufactured globally long before petitioner's patents were issued. The CA denied petitioner's motion for reconsideration. The Petition: Petitioner seeks review of the CA's decision, arguing that the CA improperly considered questions of fact in a certiorari proceeding, erred in taking judicial notice of private respondent's self-serving facts, disregarded the RTC's factual findings, and lacked basis to grant an injunction in favor of private respondent.
Issue(s)
Whether the Court of Appeals committed grave abuse of discretion in setting aside the writ of preliminary injunction issued by the trial court, and whether petitioner established a clear legal right to be protected by a writ of preliminary injunction. Whether private respondent's "miyata" sing-along system infringes upon petitioner's utility model patents. On the Court of Appeals' findings.
Ruling
The Supreme Court reversed and set aside the decision of the Court of Appeals and reinstated the order of the trial court granting the writ of preliminary injunction. The Court directed the trial court to continue with the proceedings on the main action.
Ratio Decidendi
On the propriety of the Court of Appeals' action and the existence of a clear legal right: The Court reiterated that injunction is a preservative remedy to protect substantive rights and is granted when the plaintiff alleges facts sufficient to constitute a cause of action and demonstrates that the injunction is reasonably necessary to protect legal rights pending litigation. For a preliminary injunction to issue, there must be the existence of a right to be protected and that the facts against which the injunction is directed are violative of that right. The right must be clear and positive. In this case, the issuance of Letters Patent No. UM-5269 and UM-6237 to petitioner created a prima facie presumption of their correctness and validity. The burden shifted to respondent Janito Corporation to overcome this presumption with competent evidence, which it failed to do. The testimony of Janito Cua, President of Janito Corporation, revealed inconsistencies and lack of concrete proof regarding the alleged prior existence and public use of similar sing-along systems, undermining their defense. On patent infringement: Under Section 37 of The Patent Law, a patentee has the exclusive right to make, use, and sell the patented machine or product. Infringement occurs when the essential or substantial features of the patented invention are taken or appropriated, or when the alleged infringing device performs the same function, accomplishes the same result by substantially identical means, and operates on substantially the same principle. Petitioner established that Janito Corporation was manufacturing a similar sing-along system. While Janito Corporation cited differences between its "miyata" equipment and petitioner's patented models, its comparison was limited to the first model and disregarded the second, improved model. Crucially, Janito Corporation did not refute petitioner's allegations that both systems performed the same functions, were used for singing and amplifying voice, utilized minus-one or multiplex tapes, recorded singing and accompaniment, enhanced voice with echo effects, were equipped with cassette tape decks for playback and recording, were encased in box-like cabinets, and could be used with microphones. These substantial similarities in function, operation, and result indicated a strong likelihood of infringement. On the Court of Appeals' findings: The Court found that the CA erred in disregarding the factual findings of the RTC and in considering questions of fact in a certiorari proceeding. The CA's conclusion that there was no infringement was based on an incomplete comparison and a failure to properly assess the evidence presented, particularly the admissions and inconsistencies in the testimony of Janito Cua. The CA's reliance on the universality of karaoke systems as a defense was insufficient to overcome the prima facie validity of petitioner's patents. Therefore, the CA committed grave abuse of discretion in setting aside the preliminary injunction.
Main Doctrine
A writ of preliminary injunction may be granted when the plaintiff establishes a clear legal right and that the acts complained of are violative of such right. In patent infringement cases, the issuance of a patent creates a prima facie presumption of its correctness and validity, shifting the burden to the respondent to overcome this presumption with competent evidence. Failure to present such evidence, particularly regarding the novelty of the patented utility model, justifies the issuance of an injunction.
