TL;DR

Taiwanese courts strictly scrutinize non-compete clauses. To be enforceable, they must protect legitimate business interests, have a reasonable duration, offer fair compensation, and define a clear scope. Overly broad or lengthy clauses, especially without compensation, are often deemed invalid.

Demystifying Non-Compete Clauses: Is 24 Months Really Enforceable?

A sales manager resigns. The following month their name turns up on a competitor's business card. HR pulls the employment agreement: non-compete, twenty-four months. This looks like a straightforward win.

In court, the first question is not whether they breached it. It is what the company gave in exchange for those twenty-four months.

A non-compete is not enforceable because it was signed. Article 9-1(1) of the Labor Standards Act sets out four requirements, and Article 9-1(3) makes the agreement void if any one of them is not met — four tests, and failing any one of them leaves the whole clause with nothing behind it.

Requirement 1: Protecting Legitimate Interests – Why a Non-Compete?

First, the company must be able to demonstrate that the non-compete clause is intended to "protect its legitimate interests." This isn't just a platitude; it requires concrete factual support. For example, the employee may have had access to the company's critical technologies, proprietary formulas, client lists, marketing strategies, or business plans during their employment – information that qualifies as trade secrets or confidential business information. If the employee engages in a highly competitive business after departure and utilizes this information, it would indeed harm the company. Conversely, if the employee's job duties did not involve access to any core confidential information, or if their post-departure industry is unrelated to the company's business, a court might find no necessity for protection and invalidate the clause, even if one was signed.

Why Companies Lose

Courts will examine whether the company has specific evidence proving the employee accessed protected information, whether that information possesses secrecy and economic value, and whether the company has taken reasonable measures to protect it (refer to the definition under the Trade Secrets Act). If the company vaguely claims to "protect company interests" without proving the employee accessed specific trade secrets, or if the information is already public, this requirement is difficult to meet.

How to Improve

In the agreement, you should describe the types of confidential information the employee has access to during employment as specifically as possible. For instance: "The employee agrees that, by virtue of their position, they have the right to access, know, and handle the company's customer databases, product development blueprints, patent technology documents, marketing strategy reports, etc." This can be supplemented with internal company confidentiality policies or non-disclosure agreements signed by the employee as supporting evidence.

Sample clause: The employee agrees that, during their employment and after termination, they shall not disclose, reveal, or utilize the company's trade secrets to any third party engaged in business competitive with the company's business. The company's trade secrets include, but are not limited to: customer lists, supplier information, product development plans, technical documents, patent application information, marketing strategies, financial statements, business plans, etc., and the company has taken reasonable protective measures.

Requirement 2: Reasonable Duration – Is 24 Months Excessive?

Start with the statutory ceiling. Article 9-1(4) of the Labor Standards Act caps post-termination non-compete periods at two years, and any period longer than that is shortened to two years by operation of law. So 24 months is not beyond the permitted range — it is the ceiling itself; write 36 months and the excess simply has no effect.

Within that ceiling, the period still has to satisfy the "not exceeding a reasonable scope" requirement in Article 9-1(1)(iii). That turns on the confidentiality of the information the employee had access to, the information's lifecycle, the company's need to protect it, and the employee's difficulty in finding new employment. The real question is whether you can explain why this trade secret still needs protecting in month 24 — writing the statutory maximum straight into the contract leaves the entire burden of justification on you.

Why Companies Lose

What usually loses the case is not the figure 24 months in itself, but the company having no account of why it needs 24 months. The period restricts the employee's right to work, so requirement three asks that it be proportionate to the interest being protected: if the company cannot show that the trade secret's lifecycle actually runs to the end of the period, and cannot point to a concrete risk of the employee exploiting it, that requirement fails — and under Article 9-1(3) the consequence is that the whole agreement is void, not that it is trimmed back to whatever length a court considers reasonable.

How to Improve

When setting the duration, align it as closely as possible with the industry's information update speed and the actual lifecycle of confidential information. If there are special reasons requiring a longer period, thoroughly explain them in the agreement and ensure they are consistent with other requirements (especially reasonable compensation) to enhance persuasiveness. For example, if the employee accessed highly core and difficult-to-replicate technology, and the company invested heavily in its development, a longer period might be considered, but it must be accompanied by higher compensation.

Sample clause: The employee undertakes that, for a period of twelve (12) months from the effective date of termination, they shall not work for, or directly or indirectly engage in, a business competitive with the company's business, or operate a similar business themselves.

Requirement 3: Reasonable Compensation – No Compensation, Questionable Validity

This is a critical factor for a non-compete clause to be recognized by courts and is often overlooked by many companies. According to the Labor Standards Act and judicial precedents, restricting an employee's post-employment freedom to work requires providing "reasonable compensation." This compensation doesn't necessarily have to be post-termination salary but must be sufficient to offset the damages incurred by the employee due to this restriction, ensuring their living standards are not unduly affected. The amount, payment method (lump sum or installments), and duration of compensation must be carefully designed.

Why Companies Lose

The most common reasons for losing are "failure to provide reasonable compensation" or "compensation is clearly unreasonable" — and this requirement comes with a figure you can check against. Article 7-3 of the Enforcement Rules of the Labor Standards Act sets reasonable compensation at no less than 50% of one month's average wage at the time of departure, per month, payable either as a lump sum prepaid on departure or monthly thereafter. Fall below that, or offer nothing at all, and the agreement falls outside Article 9-1(1)(iv) — which under Article 9-1(3) makes it void.

Note Article 9-1(2) as well: reasonable compensation does not include anything the employee received during employment. Arguing that the salary, bonuses or allowances already paid "included" the non-compete consideration is a route the statute closes off expressly.

How to Improve

The agreement should clearly stipulate the content and method of compensation. Common compensation methods include: 1. Periodic payments post-termination: A fixed amount paid monthly or quarterly until the non-compete period expires. 2. Lump-sum payment: A single payment made at the time of termination. 3. Advance payment: Pre-payment during employment in the form of bonuses or allowances, ensuring the value of the advance payment is equivalent to the post-termination compensation benefit.

The calculation of the compensation amount can reference the employee's average salary before termination, the length of the non-compete period, and the employee's expected income during that period, ensuring it has substantial economic meaning.

Sample clause: To compensate the employee for the restrictions imposed by this non-compete agreement, the company agrees to pay a monthly compensation equivalent to fifty percent (50%) of the employee's average salary in the last month prior to termination, until the expiration of the non-compete period stipulated herein. Should the employee violate the provisions of this clause during the non-compete period, the company reserves the right to immediately cease payment of any remaining compensation, without prejudice to the company's right to claim damages as provided by applicable laws.

Requirement 4: Clear Scope – Ambiguity Renders It Void

The validity of a non-compete clause also depends on the clarity of its defined scope. This includes the "scope of prohibited business activities" and the "prohibited geographical area." If the defined scope is overly broad or vague, for instance, merely stating "shall not engage in business identical or similar to the company's" without defining what "identical or similar" means, or restricting the geographical area globally, a court may deem the provision too vague for the employee to clearly understand their obligations, thus affecting its validity.

Why Companies Lose

Courts believe employees should clearly understand the restrictions imposed upon them. If the "scope of business activities" is vague, such as simply stating "shall not engage in any business related to the company," without specifying the scope of "related," or if the "geographical scope" is excessively broad, like "not within the Asian region," it may be considered an excessive restriction on the employee and lack clarity, making it difficult to enforce.

How to Improve

In the agreement, define the "scope of prohibited business activities" as specifically and clearly as possible. For example, list the company's current and future primary product lines, service offerings, and target markets, and specify that the employee shall not engage in business activities directly competing with these specific items after termination. Similarly, geographical restrictions should be reasonable, such as limiting them to the company's primary operating regions or key customer locations, rather than unreasonably broad areas.

Sample clause: The employee undertakes that, for a period of three (3) years following termination, they shall not, within the territory of Taiwan, be employed by, participate in, operate, assist, or in any way engage in business activities that directly compete with the company's current and future primary product lines (including but not limited to Category A software products, Category B cloud services) within the next three (3) years.

The Four Tests, Point by Point

  • Does the company have specific evidence that the employee accessed protected trade secrets?
  • Is the non-compete duration reasonable and aligned with the information's lifecycle?
  • Is "reasonable compensation" provided to the employee to offset their losses?
  • Are the defined business and geographical scopes clear, specific, and reasonable?

A Signature Does Not Make the Clause Hold

Many believe that if an employee signs a non-compete clause, it is automatically enforceable. This is a significant misunderstanding. Courts substantively review the clause's content for compliance with legal requirements and principles of fairness, not just the signature. Even if signed, a clause with defects in the aforementioned requirements may still be deemed invalid.

FAQ

After an employee resigns, how can I prove they violated the non-compete clause?

Proving a violation requires collecting concrete evidence. For example, the employee immediately takes a key position at a highly competitive rival company, with job duties closely related to their previous role. Alternatively, evidence might show the employee using the former company's client lists or technical documents to solicit former clients or develop similar products. Ensure evidence collection is lawful, and consider seeking professional legal assistance.

If I only restrict an employee from "engaging in" specific business activities without providing compensation, is it valid?

In Taiwan, restricting an employee's post-employment freedom to work generally requires "reasonable compensation." Without compensation, the clause's validity is significantly weakened, and courts are likely to deem it invalid due to unfairness, unless the company can prove the restriction's necessity is extremely high and the impact on the employee is minimal – a rare scenario.

Can the non-compete period be extended indefinitely?

No. Article 9-1(4) of the Labor Standards Act imposes a hard ceiling: two years at most, and anything longer is shortened to two years by operation of law. Nor is anything under two years automatically safe — the period must still fall within the "reasonable scope" required by Article 9-1(1)(iii), and the company has to be able to explain why the trade secret it is protecting needs a period that long.

After an employee resigns, can I demand the return of all data they accessed?

Yes, this is the company's right to protect its trade secrets. Upon resignation, employees are obligated to return all company property, including computers, phones, documents, and data. If the employee had access to company trade secrets, the company can also require the employee to sign a resignation declaration confirming the return of all materials and their commitment to abide by the non-compete clause.

If the non-compete clause is deemed invalid by the court, are there other ways for the company to protect itself?

Even if a non-compete clause is invalid, the company can still assert claims under laws like the Trade Secrets Act if the employee misappropriates or improperly uses company trade secrets, holding them liable for civil damages and potentially criminal penalties. Therefore, properly protecting trade secrets themselves is as important as drafting an effective non-compete clause.

How can I determine if my non-compete clause is valid?

You can review your contractual clauses against the four requirements mentioned above (protecting legitimate interests, reasonable duration, reasonable compensation, and clear scope). If you have doubts about any aspect, it is advisable to seek professional legal counsel or use contract management tools for an initial screening to ensure your rights are protected.
