Drafting Enforceable Confidentiality and Non-Disclosure Clauses involving Trade Secrets for Philippine Subsidiaries

Introduction: Why confidentiality drafting matters for Philippine subsidiaries

Foreign parent companies operating through Philippine subsidiaries often rely on unpatented manufacturing know-how, formulations, and internal databases rather than registered IP. In disputes—whether with employees, contractors, or even shareholders—confidential information may be exposed through discovery, regulatory filings, or workplace transitions. Philippine law generally recognizes a privilege against compelled disclosure of trade secrets and allows reasonable contractual restrictions, but enforceability depends heavily on how the confidentiality obligation is defined, how access is controlled, and how the agreement is implemented.

Governing Philippine rules that support trade secret protection

Philippine protection for trade secrets comes from a mix of evidence rules, corporate law, and jurisprudence recognizing the proprietary character of confidential commercial and industrial information.

1) Privilege against compelled disclosure in court proceedings

The 2019 Amendments to the Rules on Evidence expressly recognize a privilege relating to trade secrets: a person cannot be compelled to testify about any trade secret unless non-disclosure would conceal fraud or otherwise work injustice, and if disclosure is directed, the court must adopt protective measures. (A.M. No. 19-08-15-SC, 23 April 2019, Rule 130, Sec. 26)

This matters for multinational groups because confidentiality drafting should anticipate litigation: the agreement should support motions for protective orders, in camera inspection, redaction, and “attorneys’ eyes only” handling if disclosure becomes unavoidable.

2) Supreme Court recognition of trade secrets as protected information

In Air Philippines Corporation v. Pennswell, Inc., G.R. No. 172835, 13 December 2007, the Supreme Court treated product formulation/ingredients as trade secrets and refused compulsory disclosure absent a compelling, indispensable need for doing justice. The decision underscores that courts will not compel revelation merely because a party claims it needs the information for its case, especially where the disclosure would destroy the economic value of the secret.

3) Corporate records access and confidentiality limits under the Revised Corporation Code

Philippine subsidiaries must also manage confidentiality against “internal” requesters such as shareholders and directors. Under the Revised Corporation Code, corporate records are generally open to inspection, but the inspecting party remains bound by confidentiality rules under prevailing laws, including rules on trade secrets and the Rules of Court. (R.A. No. 11232, 2019, Sec. 73)

The SEC has also issued implementing guidance on inspection disputes and reiterates confidentiality obligations tied to trade secrets and data privacy. (SEC Memorandum Circular No. 25, s. 2020; SEC Opinion No. 24-14, 2024)

4) Reasonable restrictive covenants may be enforced when tied to confidential access

While your focus is non-disclosure, Philippine jurisprudence on restrictive covenants helps in drafting “non-use” and related protections. In Tiu v. Platinum Plans Phil., Inc., G.R. No. 163512, 28 February 2007, the Supreme Court upheld a non-involvement clause where it was reasonable and justified by the employee’s exposure to sensitive marketing strategies, emphasizing that contractual stipulations are binding if not contrary to law, morals, good customs, public order, or public policy.

5) Limits: vague “confidential information” definitions can backfire

Overbroad drafting can create enforceability risks. In Yonzon v. Coca-Cola Bottlers Philippines, Inc., G.R. No. 226244, 10 March 2021, the Supreme Court criticized company rules that were so broad they could treat almost anything as confidential, finding vagueness and unfairness in their application. While the case arose in a labor dismissal context, it offers a drafting lesson: define protected information with sufficient clarity and link protection to legitimate business interests.

What counts as a “trade secret” in Philippine disputes (concept and proof points)

Philippine decisions commonly treat as trade secrets information that (1) is not generally known or readily ascertainable by the public, (2) carries economic value from being secret, and (3) is subject to efforts to maintain secrecy. This is consistent with how the Supreme Court described the proprietary/economic nature of confidential product formulations in Air Philippines Corporation v. Pennswell, Inc., G.R. No. 172835, 13 December 2007.

For foreign parent groups, this means enforceability is not only about paper clauses. If the subsidiary’s practices show weak secrecy controls (e.g., uncontrolled access to formulas or databases), the “trade secret” claim becomes harder to defend.

Drafting enforceable NDA clauses for Philippine subsidiaries (what to include)

Below are provisions commonly used in Philippine-facing NDAs and confidentiality clauses, tailored to protect unpatented manufacturing processes and corporate databases.

A. Define “Confidential Information” with precision and categories

Avoid a definition so broad that it appears unfair or vague. Use a defined term with clear categories and examples, and specify inclusions and exclusions.

Recommended structure (use category-based drafting):

• Manufacturing and process know-how: formulations, recipes, process parameters, tolerances, SOPs, batch records, yield data, equipment settings, QC/QA protocols, suppliers tied to process performance.
• Technical documentation: drawings, process maps, prototypes, testing results, failure analyses.
• Corporate databases and datasets: customer lists, pricing histories, demand forecasts, distributor terms, marketing and sales performance data, internal dashboards, user credentials, database schemas.
• Security and access data: system architecture, security protocols, audit logs, incident reports (as appropriate).

Exclusions should typically include information that becomes public without breach, information independently developed without use of the secret, and information rightfully received from a third party without confidentiality restrictions.

B. Add a “trade secret” sub-definition for highest-value information

Create a tiered approach: “Confidential Information” and a narrower “Trade Secrets” subset. This aligns with the evidentiary privilege under Rule 130, Sec. 26 (A.M. No. 19-08-15-SC, 2019) and helps courts justify heightened protective orders if litigation arises.

C. Impose both non-disclosure and non-use obligations

Draft two separate duties:

• Non-disclosure: no sharing with unauthorized persons, including within the corporate group unless on a need-to-know basis.
• Non-use: no use except for defined purposes (e.g., performing duties, providing services, fulfilling a specific project scope).

This is essential for manufacturing know-how and databases where misuse can occur without any “publication.”

D. Control “need-to-know” and cross-border sharing within the corporate group

Foreign parent companies often transfer process know-how and database access across borders. Your NDA should expressly allow controlled disclosure to the parent/affiliates, but require:

• Need-to-know access only;
• Equivalent confidentiality obligations for recipients (e.g., affiliate personnel, consultants);
• Security requirements (MFA, access logs, encryption, segregation of duties); and
• Return/destruction and certification on exit.

E. Specify handling rules for corporate databases and digital materials

Manufacturing secrets today are often embedded in digital systems (ERP, LIMS, MES, cloud drives). Add “handling protocols” clauses such as:

• No personal storage (no personal emails, USBs, personal cloud drives).
• Authorized devices only and company-managed accounts.
• Logging and monitoring consent for corporate systems (aligned with company policy).
• Incident reporting deadlines for suspected leaks.

F. Include “compelled disclosure” and litigation protective measures

Because the Rules on Evidence recognize trade secret privilege but allow disclosure to prevent injustice, NDAs should contain a clause requiring the receiving party to:

• promptly notify the company of subpoenas/court orders;
• cooperate in seeking protective orders; and
• limit disclosure to what is legally required.

This pairs directly with Rule 130, Sec. 26 (A.M. No. 19-08-15-SC, 2019) and strengthens requests for in camera review and other court protections.

G. Duration: separate term for trade secrets vs. ordinary confidential information

Set different durations:

• Trade secrets: for as long as the information remains a trade secret.
• Other confidential information: a fixed term (commonly 2–5 years), depending on the business cycle.

H. Remedies: injunction, damages, and equitable relief

Given the difficulty of quantifying damages from a process leak, include a clause recognizing that breach may cause irreparable harm and that the company may seek injunctive relief and other equitable remedies, consistent with Philippine court processes. Tie this to the notion that forced disclosure is limited and courts may adopt protective measures for trade secrets (A.M. No. 19-08-15-SC, 2019, Rule 130, Sec. 26).

I. Exit obligations (employees and contractors)

For Philippine subsidiaries, include a clean checklist on separation:

• return of documents/devices and revocation of access;
• deletion of copies (including personal devices if permitted/used);
• final reminder of continuing obligations; and
• certification of compliance.

Common scenarios and how the NDA should address them

Scenario 1: Local engineer resigns and joins a competitor

Use a combination of (a) clearly defined trade secrets, (b) non-use obligations, and (c) careful access control evidence. Where appropriate and reasonable, consider a limited restrictive covenant justified by confidential exposure, mindful of the reasonableness principle recognized in Tiu v. Platinum Plans Phil., Inc., G.R. No. 163512, 28 February 2007.

Scenario 2: Contractor copies a production database to finish work faster

Cover this using explicit digital handling rules, prohibition on personal storage, and audit/logging. Ensure the services agreement includes confidentiality, IP ownership (if applicable), and return/destruction with certification.

Scenario 3: Shareholder asks to inspect records that include trade secrets or personal data

Under R.A. No. 11232 (2019), Sec. 73, inspection rights exist, but the inspecting party is bound by confidentiality rules, including trade secret rules and the Rules of Court. SEC Memorandum Circular No. 25, s. 2020 and SEC Opinion No. 24-14 (2024) reflect that inspection is not a free pass to publish sensitive information and that abuse may trigger sanctions.

Drafting do’s and don’ts (summary table)

Do	Don’t	Why it matters
Define confidential information by categories and examples	Use “all information of any kind” with no limits	Overbroad definitions risk vagueness concerns similar to those discussed in Yonzon v. Coca-Cola Bottlers Philippines, Inc., G.R. No. 226244, 10 March 2021
Create a “Trade Secrets” subset and apply stricter handling	Treat all data equally	Supports court protection and confidentiality measures consistent with A.M. No. 19-08-15-SC (2019), Rule 130, Sec. 26
Include non-use, need-to-know, and security controls	Rely on non-disclosure alone	Misuse can happen without “publication,” especially for databases and process parameters
Add compelled disclosure notice and protective-order cooperation	Ignore litigation risks	Trade secret privilege is qualified; courts may allow disclosure to avoid injustice but must use protective measures (A.M. No. 19-08-15-SC, 2019)

Procedural options when a leak occurs (what companies commonly do)

When a Philippine subsidiary suspects misappropriation, companies typically proceed in stages:

• Internal containment: suspend access, preserve logs, image devices (with policy basis), and secure witnesses.
• Demand letter and exit certification: require return/destruction and written undertakings.
• Injunction-focused litigation posture: prepare to seek protective measures over trade secrets and resist unnecessary disclosure, consistent with the approach in Air Philippines Corporation v. Pennswell, Inc., G.R. No. 172835, 13 December 2007, and Rule 130, Sec. 26 (A.M. No. 19-08-15-SC, 2019).
• Corporate governance controls: if a shareholder dispute is involved, manage inspection requests under R.A. No. 11232 (2019), Sec. 73 and SEC Memorandum Circular No. 25, s. 2020.

Final observations and recommendations

For foreign parent companies, an enforceable confidentiality program in a Philippine subsidiary should be built around three elements: (1) clear drafting that identifies what is protected and why, (2) operational secrecy controls that show consistent efforts to maintain confidentiality, and (3) litigation readiness anchored on the trade secret privilege under the Rules on Evidence and the Supreme Court’s strong protection of proprietary formulations and business secrets.

As a drafting checklist, prioritize: category-based definitions, a “Trade Secrets” tier, non-use obligations, need-to-know sharing rules within the group, database handling protocols, compelled disclosure clauses aligned with Rule 130, Sec. 26, and separation/return certifications.
