Case Summary (G.R. No. 115106)
Petitioner’s Patent Claims and Product Description
Petitioner alleged ownership of utility‑model patents covering a compact, multi‑purpose audio (sing‑along/karaoke) machine: an integrated cabinet with amplifier, speaker(s), tape mechanisms, optional tuner, microphone mixer and voice‑enhancing features (echo/reverb), with controls on a control panel and internal partitions creating front and rear compartments. The record references Letters Patent No. UM‑5269 (earlier reference) and Letters Patent No. UM‑6237 (an improved model); the record also includes a quoted utility‑model patent described as Letters Patent No. UM‑5629 (dated 2 June 1985) — all described as utility models for audio equipment and all having had their terms extended.
Trial Court Findings and Issuance of Preliminary Injunction
The trial court found that petitioner was the holder of utility‑model patents and that Janito Corporation was manufacturing and selling a sing‑along system (the miyata) substantially similar to petitioner’s patented models without petitioner’s approval. On those findings, the trial court issued a writ of preliminary injunction to restrain Janito Corporation from manufacturing, using, selling or advertising the miyata sing‑along system pending further orders.
Court of Appeals’ Rationale for Setting Aside the Injunction
The Court of Appeals granted certiorari and set aside the trial court’s injunction. The Court of Appeals held that the mere fact that Janito manufactured a karaoke system did not establish patent infringement because the karaoke/sing‑along concept was a universal product manufactured and marketed worldwide prior to petitioner’s patents. The appellate court’s ruling implied that petitioner had not established the novelty or exclusive right necessary to justify injunctive relief.
Legal Issues Raised on Review
Petitioner contended that: (a) the Court of Appeals improperly resolved factual questions in a certiorari proceeding; (b) the Court of Appeals improperly took judicial notice of respondent’s self‑serving factual claims; (c) the appellate court disregarded factual findings of the trial court; and (d) there was no basis for the Court of Appeals to grant injunctive relief in favor of respondent. The overarching legal question presented was whether the Court of Appeals committed grave abuse of discretion in setting aside the trial court’s injunctive order.
Legal Standard for Preliminary Injunctions
The Supreme Court reiterated that a preliminary injunction is an extraordinary, preservative remedy to prevent threatened or continuing irreparable injury before full adjudication. The traditional requisites are: (1) a complaint alleging facts sufficient to constitute a cause of action for injunction (i.e., existence of a right to be protected), and (2) a showing that preliminary relief is necessary to protect the plaintiff’s legal rights pending trial (i.e., acts alleged are violative of that right). The Court emphasized that the writ should be granted only where there is pressing necessity to avoid injurious consequences not remediable by damages.
Patent Law Principles; Presumption of Validity and Burden of Proof
Under the Patent Law (R.A. No. 165, as amended), utility models may be patented if new and of practical utility even if not possessing the quality of invention (Sec. 55). A granted patent, if in due form, affords a prima facie presumption of correctness and validity; the Director of Patents’ decision in granting a patent is presumed correct. The onus then shifts to a defendant alleging lack of novelty or invalidity to overcome that presumption with competent evidence. Section 37 provides that a patentee has the exclusive right to make, use and sell the patented article and that unauthorized making or selling constitutes infringement.
Evidence and the Director of Patents’ Role
The Court noted that the Director of Patents decides both legal and factual questions in passing on patent applications, including whether the subject matter is new. Because petitioner introduced his patents in due form, petitioner obtained the statutory prima facie presumption of validity. Janito Corporation bore the burden to present competent evidence showing the patented models were not new (for example, proof of prior use, sale, or printed descriptions in the country).
Trial Testimony and Respondent’s Failure to Prove Prior Art
The Supreme Court reviewed trial testimony, particularly that of Janito Cua, which demonstrated that Janito Corporation had not produced documentary evidence to substantiate its claim that prior foreign manufacturers (e.g., Sanyo, Sharp, etc.) or other local products predated petitioner’s patents in the Philippines. The testimony showed uncertainty as to dates and an absence of written proof, and the trial court was not presented with adequate evidence to overcome the presumption of novelty and validity attaching to petitioner’s patents.
Comparative Analysis of Alleged Differences
Janito Corporation identified several structural and functional differences between its miyata product and petitioner’s first patented model (Utility Model No. 5269), including: casing shape (rectangular vs. substantially cubical), compartment layout, printed circuit b

- Parties: Roberto L. del Rosario (petitioner) v. Court of Appeals and Janito Corporation (respondents).
Nature of the Action and Relief Sought
- Original pleading: complaint for patent infringement filed by petitioner on 18 January 1993 before the Regional Trial Court (RTC) of Makati, Branch 57.
- Petitioner sought: (a) issuance of a writ of preliminary injunction to enjoin respondent Janito Corporation, its officers and agents from using, manufacturing, selling and advertising the “miyata” or “miyata karaoke” sing-along system, with injunction to be made permanent after trial; and (b) damages, attorney's fees and costs.
- Petitioner alleged he was the patentee of an audio equipment and improved audio equipment commonly known as the sing-along system or karaoke, covered by Letters Patent (utility model patents).
Patents and Their Descriptions (as presented in the source)
- Petitioner alleged patents: Letters Patent No. UM-5269 dated 2 June 1983 and Letters Patent No. UM-6237 dated 14 November 1986; both granted for five (5) years and each extended for another five (5) years beginning 2 June 1988 and 14 November 1991, respectively. (Source also contains a later reference to Letters Patent No. UM-5629 dated 2 June 1985; the syllabus follows the source text in presenting these references.)
- Utility Model described (UM-5269 / later cited as UM-5629 in the source): construction of an audio equipment comprising
- a substantially cubical casing with a window at its rear and upper corner and a slightly inclined control panel;
- a vertical partition wall creating a rear compartment and a front compartment serving as a speaker baffle;
- a transistorized amplifier circuit with an echo section wired in at least the printed circuit boards inside the rear compartment and attached to the vertical partition wall, operable from controls on the control panel;
- a loudspeaker mounted in the front compartment connected to the output of the main amplifier;
- a tape player mounted on the top wall of the casing connected in conventional manner to the amplifier circuit.
- Utility Model described (UM-6237): audio equipment consisting of
- a first cubical casing with an opening at its rear and upper rear portion and partition forming rear and front compartments; a removably fitted control panel with vertical and horizontal sections;
- a transistorized amplifier circuit wired in at least two printed circuit boards attached to the back of the control panel;
- one loudspeaker in the front compartment connected to the amplifier;
- improvement: control panel removably fitted to the first casing and comprising a set of tape recorder and tape player mounted on the vertical section of the control panel, connected to the amplifier;
- a second cubical casing adapted to the first casing to form a compact and portable unit with a second loudspeaker; rear compartment enclosing tape racks with a door.
- The Patent Law (R.A. 165 as amended), Section 55 (quoted in the source) recognizes patent protection for new models or implements or tools or industrial products of practical utility even if lacking the quality of invention (utility models), subject to same general provisions as patents for inventions insofar as applicable.
- The Patent Law (Section 37, as cited in the source) confers upon a patentee the exclusive right to make, use and sell the patented machine throughout the Philippines for the term of the patent; unauthorized making, using or selling constitutes infringement.
Trial Court Actions and Findings
- On 5 February 1993 the RTC temporarily restrained Janito Corporation from manufacturing, using and/or selling and advertising the miyata sing-along system or any sing-along system substantially identical to petitioner’s patented utility model until further orders.
- On 24 February 1993 the RTC issued a writ of preliminary injunction upon a bond, based on its finding that petitioner was a holder of a utility model patent for a sing-along system and that Janito Corporation, without his approval and consent, was manufacturing and selling a miyata sing-along system substantially similar to the patented utility model.
- The trial court accepted petitioner’s allegations and evidence sufficiently to justify the injunction pendente lite.
Respondent Janito Corporation’s Challenge and Contentions
- Janito Corporation filed a petition for certiorari with prayer for issuance of a writ of preliminary injunction and TRO before the Court of Appeals to challenge the RTC’s 24 February 1993 order.
- Principal contentions advanced by respondent and by the Court of Appeals (as reflected in the source):
- The fact that respondent manufactured the miyata karaoke or audio system does not ipso facto establish infringement.
- The karaoke system is a universal product manufactured, advertised and marketed in many countries long before the patents were issued to petitioner; thus, respondent asserted prior existence and non-novelty.
- Janito denied violation of petitioner’s patent rights and attempted to identify structural and functional differences between its miyata model and petitioner’s patented model(s).
Court of Appeals Decision
- On 15 November 1993 the Court of Appeals granted the writ (i.e., it set aside the RTC’s injunction) and expressed the view that there was no infringement by mere manufacture of the miyata karaoke; the CA noted that the karaoke system was a universal product predating petitioner’s patents.
- The Court of Appeals’ grant was followed by denial of petitioner’s motion for reconsideration (as referenced in the source).
- Petitioner filed the present petition for review to the Supreme Court, contesting the Court of Appeals’ factual determinations and legal conclusions.
Petitioner’s Alleged Errors by the Court of Appeals (as pleaded)
- Petitioner alleged the Court of Appeals committed the following errors:
- It was improper to consider questions of fact in a certiorari proceeding.
- It improperly took judicial notice of private respondent’s self-serving presentation of facts.
- It disregarded and disturbed the factual findings of the trial court.
- There was no basis for the Court of Appeals to grant a writ of preliminary injunction in favor of private respondent.
Evidentiary Record and Testimony Before the Trial Court
- Petitioner introduced his letters patent(s) in evidence; the source notes that a patent in due form affords a prima facie presumption of correctness and validity and that the Director o
