Trade Secrets: The Hidden Asset Protecting Your Business's Secret Recipe

Have you ever wondered why Coca-Cola tastes like nothing else on earth? Or why KFC's fried chicken has that unmistakable flavor that keeps people coming back for more, all over the world? The answer is "trade secrets" — one of the most powerful forms of intellectual property in the business world. And it's not just for multinational corporations. Even a roadside tom yum stall or a small chili paste factory back home can have trade secrets that help their business succeed. More importantly, protecting these secrets can be a closer and more challenging issue than you might think.

What Is a Trade Secret?

Under Section 3 of Thailand's Trade Secrets Act B.E. 2545 (2002), a trade secret is defined as trade information that is not generally known, has commercial value because of its secrecy, and for which the owner has taken reasonable measures to keep it confidential.

Key Elements of a Trade Secret

To make this easier to understand, the EPSILON LEGAL team breaks it down: a trade secret must satisfy three essential elements.

1. It is confidential information — not generally known to the public.

2. It has commercial value — it can genuinely be put to commercial use.

3. It is properly protected — the owner has taken appropriate measures to safeguard it.

Note: An abstract idea alone does not qualify as a trade secret, unless that idea is detailed enough to actually be put into practice.

Which Businesses Should Care Most About Trade Secrets?

In truth, trade secrets matter to every business, but they come up most often in industries built around special formulas, secret recipes, unique processes, or distinctive working methods that set a company apart. Here are some examples by industry.

Food, Restaurants, and Beverages

This sector is full of recipes, sauce formulas, cooking techniques, and ingredient-handling methods — all of which count as business "secrets."

For example, KFC's secret blend of 11 herbs and spices is famously written down on paper and locked away in a high-security vault. Similarly, Coca-Cola has kept its formula secret for more than 130 years, with only a handful of people in the world knowing the complete recipe.

Manufacturing and Industrial Sectors

Some manufacturing know-how is a closely guarded family method, while others involve proprietary formulas or production processes.

Take the case of Listerine: Pfizer paid royalties to the inventing family for more than 70 years, even after the formula had already been publicly disclosed — because the licensing contract never stated that payments would stop once the secret became known. This illustrates one of the dangers that can cause a trade secret to lose its protected status.

Technology and Software Industries

Source code, underlying logic, and service architecture all qualify — and if a product's UX or UI conceals special logic within the system, that's a strong candidate for trade secret protection too.

How to Keep a Trade Secret a Trade Secret

Maintaining trade secret protection requires:

1. Adequate protective measures — such as storing information in a safe or with a secure data-storage provider.

2. Discipline in not disclosing confidential information — whatever is meant to remain a "secret" must actually stay a secret. This applies just as much to Grandma's noodle-soup recipe as it does to appearing on a TV cooking show, where care must be taken not to reveal the full formula.
