Factual Background — Licensing and Allegations
TPI held the right to license and enforce the Yamaoka Patent. TPI granted Frescomar a non-exclusive license (March 31, 2004) requiring shipment reports and royalties; Frescomar paid an initial USD 3,000 but failed to pay subsequent royalties and failed to submit shipment reports despite TPI demands. TPI terminated the license on January 17, 2006. Frescomar manufactured and sold filtered, tasteless smoke in canisters, supplying HISI and others. HISI held or asserted rights under a different U.S. patent (Kowalski Patent) and counseled Frescomar that the smoke production fell under Kowalski’s technology, advising Frescomar not to pay royalties to TPI and to contest TPI’s claims.
Procedural History
- Frescomar and HISI filed an unfair competition complaint against TPI; TPI counterclaimed for royalties and patent infringement.
- TPI and Frescomar later entered a Settlement Agreement and jointly moved to dismiss their respective claims; the RTC granted dismissal with prejudice as to Frescomar while the case continued as to HISI. TPI’s counterclaims against Frescomar were dismissed with prejudice pursuant to the joint motion; TPI’s counterclaims against HISI were later prosecuted ex parte after dismissal of HISI’s separate claim for failure to prosecute.
- The RTC found Frescomar infringed the Yamaoka Patent and held HISI jointly and severally liable for contributory infringement, but because TPI had released Frescomar via settlement, Frescomar and HISI were not ordered to pay patent damages; the RTC nonetheless found HISI liable for tortious interference and awarded various damages and attorney’s fees.
- The Court of Appeals affirmed tortious interference damages but deleted awards for moral and exemplary damages, and modified attorney’s fees. Both parties elevated issues to the Supreme Court.
Supreme Court’s Two-Step Approach to Patent Infringement
The Court reaffirmed the two-step framework: (1) interpret the patent claims to determine the scope and meaning; (2) compare the accused product/process to the properly interpreted claims to ascertain literal infringement or infringement under the doctrine of equivalents. The Court emphasized that patent claims, like a technical description of land, define the boundary of a patentee’s protection; anything outside the claims forms prior art.
Claim Construction — The Yamaoka Patent (Claim 1)
Claim 1 is a process claim for curing raw tuna meat by “extra-low temperature smoking” and lists four essential steps: (1) burning smoking material at 250°C to 400°C; (2) passing produced smoke through a filter to remove mainly tar; (3) cooling the filtered smoke to between 0°C and 5°C while retaining preservative/sterilizing ingredients; and (4) smoking tuna meat by exposing it to the filtered and cooled smoke. Claim 2 adds preparatory steps to the tuna meat but depends on Claim 1. The patent claims protect the method of curing tuna meat, not the smoking apparatus per se.
Nature of the Accused Product/Process
Frescomar produced canned filtered smoke (using machines patterned after Pescarich/Yamaoka designs with modifications) and sold these canisters to HISI and others. Frescomar’s production process stopped at manufacture of smoke; it did not itself perform the complete claimed method of curing tuna meat (i.e., it did not perform the step of exposing tuna meat to smoke cooled to 0–5°C). The smoke-generating machines and the smoke product were disclosed in the patent description but were not claimed independently in Claim 1.
Patent Scope and Prior Art — Machine and Smoke Not Claim-Limited
Because the claims — not the descriptive embodiments — determine patent scope (Section 75), the smoking machine disclosed in the description (a conventional smoking apparatus with filtering and cooling units) is not protected unless claimed. Unclaimed subject matter disclosed in the patent description constitutes prior art. Evidence showed the smoke machines were patterned on prior Pescarich/Yamaoka designs and that Frescomar’s smoke machine therefore fell within prior art; the machine itself was not claimed and thus not protected under Claim 1.
Direct Infringement Analysis — Frescomar Did Not Perform All Claim Elements
Section 76.1 prohibits unauthorized use of a patented process. The Court found that Frescomar, at most, carried out the burning and filtering steps (the first two elements) but did not perform the cooling-to-0–5°C and exposure-of-tuna steps essential to Claim 1. Because the full patented method (all claim elements) was not performed by Frescomar, Frescomar did not directly infringe the Yamaoka Patent.
Indirect Infringement Analysis — HISI Not Liable for Contributory or Inducement Infringement
Indirect infringement under Section 76.6 presupposes a direct infringer. Contributory infringement requires proof that the third party provided a component knowing it was especially adapted for infringing use and not suitable for substantial non-infringing use. Inducement requires active inducement of another to perform the patented invention. The Court held that: (a) the filtered smoke is not a product obtained directly or indirectly from the patented curing process — it is a component or material used in a process someone else might perform; (b) there was insufficient proof that HISI knew the smoke would be used to perform the entire patented method at extra-low temperatures or that the smoke had no substantial non-infringing uses; and (c) therefore HISI cannot be held liable under Section 76.6 for inducement or contributory infringement given the absence of a proven direct infringement by any party.
Settlement Agreement and Waiver — TPI Released Frescomar from Past Liabilities
The Settlement Agreement between TPI and Frescomar included a covenant by TPI not to pursue Frescomar (and named individuals) for liability or royalties related to past infringement of U.S. Patent No. 5,484,619 and international counterparts (the Yamaoka Patent family), and the parties jointly moved to dismiss with prejudice. The Court interpreted the settlement and the joint motion to dismiss as an effective release and waiver by TPI of claims against Frescomar for past infringement, noting that TPI’s later attempt to contend otherwise was inconsistent with the parties’ dismissal and joint waiver. Consequently, even if the smoke were an indirect product, Frescomar could not be held liable for past patent infringement claims that were the subject of the settlement and dismissal with prejudice.
Tortious Interference — Elements and Findings Against HISI
Under Article 1314 and established jurisprudence (So Ping Bun, Lagon), tortious interference requires: (1) a valid contract; (2) knowledge by a third person of that contract; and (3) interference without legal justification or excuse, typically with malice or wrongful motive. The Court found all three elements satisfied: (1) the license agreement between TPI and Frescomar existed; (2) HISI (through officers and consultants) knew of the license; and (3) HISI induced Frescomar to stop paying royalties and to falsify temperature records, motivated by the desire to weaken TPI’s position in separate U.S. litigation (a wrongful motive), which is not a lawful business justification. HISI’s conduct included urging Frescomar not to pay royalties and instructing falsification of records to support HISI’s position in foreign proceedings; these actions constituted malicious inducement and therefore tortious interference.
Damages for Tortious Interference — Compensatory (Temperate), Exemplary, and Moral Damages
- Compensatory/Actual damages: TPI failed to present sufficiently precise proof of actual pecuniary loss (e.g., the precise number of tuna products produced under the license). The Court therefore treated damages as temperate (Article 2224), exercising judicial discretion to fix a reasonable award. Using TPI’s own final demand (USD 22,534.80) and pr

Procedural Posture and Relief Sought
- Consolidated Petitions for Review on Certiorari (G.R. Nos. 226445 and 226631) assail the Court of Appeals Decision dated September 9, 2015 and Resolution dated August 10, 2016 in CA-G.R. CV No. 02845-MIN.
- Core questions on appeal: (1) whether Frescomar Corporation’s production of smoke infringed Philippine Patent No. 31138 (the Yamaoka Patent); (2) whether Hawaii International Seafoods, Inc. (HISI) is liable for contributory infringement and/or tortious interference; and (3) whether TPI released Frescomar from liability.
- Lower-court rulings: RTC (Branch 23, General Santos City) January 25, 2010 decision found Frescomar infringed the Yamaoka Patent and held HISI jointly liable for contributory infringement, but concluded Frescomar’s liability was waived by a Settlement Agreement; RTC also awarded TPI damages against HISI for tortious interference; CA on September 9, 2015 affirmed most of RTC’s judgment but deleted awards for moral and exemplary damages, and modified attorney’s fees and costs; CA denied motions for partial reconsideration on August 10, 2016.
- The Supreme Court’s disposition: Petitions denied; Court of Appeals Decision and Resolution affirmed with modification (see “Disposition / Remedies” section).

- Feb. 13, 2006: Frescomar and HISI filed Complaint for Unfair Competition and Injunction against TPI; TPI filed Counterclaim demanding royalties.
- August 23, 2007: TPI and Frescomar entered into a Settlement Agreement. Sept. 25, 2007: Joint Motion to Dismiss filed by Frescomar and TPI; Oct. 4, 2007: RTC granted Joint Motion, dismissing Civil Case No. 7565 (Frescomar) with prejudice and dismissing Civil Case No. 7566 with prejudice with respect to Frescomar but continuing as to HISI.
- Frescomar later defaulted on the agreed royalty payments to TPI under the settlement.
- RTC proceedings were suspended and later lifted; TPI’s counterclaims proceeded, with RTC allowing TPI to present ex parte evidence after dismissing unfair competition case for failure to prosecute (Sept. 4, 2008).
- RTC issued decision Jan. 25, 2010 resolving counterclaims; CA affirmed with modifications Sept. 9, 2015; CA denied reconsideration Aug. 10, 2016; consolidated appeals to the Supreme Court.
License Agreement — Key Provisions and Rights
- Grant: non-exclusive license to make, use, import, purchase, sell, or offer to sell products protected by Yamaoka Patent.
- Reporting and royalties: Frescomar to submit shipment reports for royalty computation; exemption from royalties possible upon Frescomar’s request if products believed to fall outside patent scope.
- Stated definition of “Licensed products”: “tuna products produced by processes which, in the absence of this License, would infringe at least one claim of the Yamaoka Patents.”
- License enforcement and arbitration rights: TPI had rights to enforce patents and collect royalties; license contained arbitration-related provisions referenced in litigation.
Testimony and Trial Evidence (TPI’s Ex Parte Presentation)
- Witnesses presented by TPI: Francisco Santos (Frescomar VP), Eliseo Garay (former YNC plant manager and later HISI senior technical consultant), Shem Makiputin (Pescarich former smoke machine operator), Jake T. Lu (TPI President), personnel to support litigation expenses, Andrestine Tan and Charlie Ng (to support moral damages claim).
- Francisco’s testimony: Frescomar contracted former Pescarich employees to fabricate smoke machine patterned after Pescarich design; Frescomar delivered about 2,389 canisters to HISI; Kowalski advised Frescomar to claim use of Kowalski Patent to avoid paying royalties to TPI; Frescomar initially claimed smoke sales not covered by License Agreement; Frescomar later agreed to pay USD 22,534.80 but failed to do so.
- Eliseo’s testimony: Frescomar used the Yamaoka-patterned smoke machine to produce smoke; processing temperatures used allegedly within Yamaoka Patent spectrum; he ordered falsification/retroactive recording of temperature logs to make them appear within Kowalski Patent temperature ranges (higher than Yamaoka’s 0–5°C cooling parameter).
- Shem’s testimony: corroborated manufacture and antedating of records; confirmed Frescomar hired him to operate two machines patterned after Pescarich machines.
- Jake Lu’s testimony: established TPI’s rights under license and noted U.S. patent infringement action filed by TPI against HISI in Dec. 2004; explained Frescomar’s belief that paying royalties to TPI would imply HISI’s infringement of Kowalski Patent.
Legal Standards and Authorities Applied
- Patent protection scope determined by patent claims; claims are to be interpreted in light of description and drawings but description cannot expand claims (Intellectual Property Code, Sec. 75; Sec. 24 on prior art).
- Patent infringement under Intellectual Property Code: Section 76.1 (civil action for making, using, offering for sale, selling, or importing a patented product or product obtained directly or indirectly from a patented process, or use of a patented process without authorization); Section 76.6 (indirect infringement — inducement and contributory infringement; contributory infringement requires knowledge that provided component is especially adapted for infringing and not suitable for substantial non-infringing use).
- Two-step infringement analysis (as discussed in Phillips case): (1) interpret claims to determine scope and meaning; (2) compare accused product/process against properly interpreted claims using literal/infringement-by-equivalents tests.
- WIPO illustrative examples used to explain direct vs. indirect infringement and to differentiate when a product that includes additional elements still infringes and when omission of claim element defeats infringement.
- Dismissal principles under Rule 17, Section 2 of the Rules of Court: plaintiff may move to dismiss complaint; if a defendant filed counterclaim before service of plaintiff’s motion, dismissal limited to complaint but counterclaim can be resolved in same action (and defendant may elect separate action within 15 days).
- Tortious interference (Article 1314 Civil Code and So Ping Bun v. Court of Appeals): elements — (1) existence of valid contract; (2) knowledge of contract by third person; (3) interference without legal justification or excuse; wrongful motive or malice may render action unjustified; mere economic interest or business advantage is insufficient to establish tortious interference.
