Who Owns Your K-Beauty Formula? IP Rules Before an ODM Deal

Most founders read an ODM contract for two things: price and delivery date. The clause that decides whether the brand is really theirs gets skimmed. Ask yourself one question before you sign. If this factory doubled its price next year, could you take your hero product somewhere else?

Four assets decide the answer: the brand name, the formula, the packaging artwork and molds, and the regulatory file. Each has a default owner, and it is rarely you. Here is how I would map them before the first purchase order.

Who Owns What When a Korean ODM Makes Your Product?

In a typical ODM deal, the factory treats the formulas it develops as its own know-how, and the brand owns the name it registers. Everything in between gets settled by the contract, or by nobody. An ODM (original design manufacturer) is a factory that develops a product as well as making it. That is why its starting position on the formula differs from a filler that only follows your recipe.

A stock formula is a ready-made formula from the ODM's catalog that several brands can buy and label. A custom formula is developed against your brief. The difference shapes everything below, and our comparison of off-the-shelf vs custom Korean ODM formulas covers the cost and timing side.

Why Ownership Became a Deal Issue for K-Beauty Brands

Ownership gaps stay invisible until three ordinary moments: switching factories, selling the company and expanding abroad. Each one forces the question of what the brand actually holds.

Switching factories. Price, quality or capacity problems happen. If the formula is not yours, a move means reformulating, retesting and relaunching a product your customers already know.

Selling the brand. Buyers check whose name is on the trademark and what the manufacturing contract says about formula rights. The separate piece on what acquirers check in a K-beauty brand goes deeper. The cleanup is cheaper on day one than in diligence.

Expanding abroad. Large Korean brands plan for this. WIPO's case study on APR, the company behind Medicube and Aprilskin, notes that it weighs the risk of imitation or pre-emptive registration when choosing where to file (WIPO case study). An indie brand made in Korea faces the same risk with fewer resources.

Is a US Trademark Enough If You Manufacture in Korea?

No. Trademark rights are territorial, and a US registration does not protect your name in another country (USPTO on protecting IP overseas). South Korea runs a strict first-to-file system, where whoever files first generally has superior rights regardless of who used the mark first (Harris Sliwoski on Korean trademarks).

First-to-file means the trademark office ranks rival claims by filing date, not by who created or used the name. That matters even if you never plan to sell in Korea. Your brand name sits on briefs, sample labels, artwork files and carton proofs that pass through a factory and its suppliers. Bad-faith filings can be challenged in Korea, but the burden of proof falls on the earlier user. Filing first is simpler than winning later.

A clean filing order looks like this:

1. Clear and file in the US first. Search the name, then file for your cosmetic goods.
2. Extend to Korea while the clock runs. A Korean application filed within six months of the US filing can claim the US date under the Paris Convention. You can also designate Korea in a Madrid Protocol application based on your USPTO filing (USPTO guide to Korea).
3. Ask about a Hangul version. If Korean shoppers will say the name in Korean, ask your agent whether to file a transliteration too.
4. File before the name leaves your laptop. The best time is before the first brief goes to any factory. The second best time is today.

The Formula Clause Decides Whether You Can Ever Switch Factories

Your ingredient list becomes public on launch day, but your formula does not. US labels list ingredients above 1 percent in descending order of predominance, followed by those at or below 1 percent in any order (21 CFR 701.3). A competitor learns what is inside, not the exact percentages, raw material grades or process. That is the real asset, and it usually sits in the ODM's files.

For a stock formula there is nothing to negotiate: the factory can sell it to the next brand. For a custom formula, these are the terms that decide your future options:

• Ownership or license. Who owns the formula developed for your brief? If the ODM keeps it, ask for an exclusive license at minimum.
• Exclusivity scope. Define what the factory cannot sell to others: the same formula, close variants, which product types, which territories and for how long.
• Disclosure or escrow. The full formula with percentages, raw material specs and process notes, either delivered to you or held by a third party and released if the ODM stops supplying.
• Transfer support. The right to have the formula made elsewhere, and a duty to help with the technical handover.
• Change control. No raw material, supplier or grade change without your written approval.

Ownership and exclusivity are commercial terms, so expect them to affect the price. Get that price in writing too. And do not assume that paying a development fee means you own the result. If the contract is silent, you have a dispute, not a formula.

What Does Trade Secret Law Expect From a Small Brand?

Trade secret law protects a formula only if you treat it as a secret. Under US federal law, a trade secret is information, formulas included, that has value because it is not generally known. Its owner must also take reasonable measures to keep it secret (18 U.S.C. § 1839).

Reasonable measures do not mean a vault. For a small brand, they look like this:

• Sign before you share. Put an NDA in place with each factory and designer before the brief, the target spec or the brand name goes out.
• Cover use, not just disclosure. A non-use clause stops a factory from reusing your brief for another client, which plain confidentiality does not.
• Share on a need-to-know basis. Mark documents confidential and keep the full formula with as few people as possible.
• Write for the place the secret lives. Your formula sits in Korea. Ask counsel whether the agreement should be in Korean and enforceable there.

A patent is the other route. It trades public disclosure for a limited term of exclusive rights, which suits a genuinely new delivery system better than a serum built from familiar ingredients.

Six Moves to Make Before You Sign the First PO

Settle ownership while you still have bargaining power, which means before the deposit. These six moves close the gaps that are hardest to fix after launch.

1. File the trademark. US first, then Korea through the six-month priority window or Madrid.
2. Sign an NDA with non-use terms before the brief goes out.
3. Write the formula terms. Ownership or an exclusive license, disclosure or escrow, and transfer support.
4. Get artwork assigned. A contractor's commissioned work counts as work made for hire only in a short list of categories, and only with a signed agreement (Copyright Office Circular 30). Packaging art usually needs a written assignment instead.
5. Name the mold owner. If you pay for custom molds or tooling, the PO should say who owns them and how they get released.
6. Write data access into the deal. Under MoCRA, the responsible person, usually the brand named on the label, must keep records that support each product's safety and must list products with FDA. The factory registers its own facility (FDA MoCRA overview). Your contract should guarantee the specs, test data and batch records behind that duty.

Our guide to FDA and MoCRA requirements for Korean skincare covers the regulatory side. The list of documents to demand from your Korean ODM at ship-out shows what that data looks like.

Frequently Asked Questions

Can my Korean ODM sell my formula to another brand?
If it is a stock formula, yes. Catalog formulas exist to be sold to many brands. If it is a custom formula, the answer sits in your contract. Without an ownership or exclusivity clause, you have little to stand on when a close variant turns up under another label. Ask for exclusivity in writing and define it by product type, territory and time.

Do I need a Korean trademark if I only sell in the US?
It is cheap insurance. Korea is first-to-file, and your brand name already travels through Korean factories and suppliers. A Korean filing made within six months of your US application can claim the US filing date under the Paris Convention.

Should I patent my skincare formula?
Only if something in it is new and non-obvious, such as a delivery system. A patent publishes how the invention works in exchange for a limited term of exclusive rights. A trade secret lasts as long as it stays secret, which suits most formulas built from known ingredients.

Who keeps the FDA product listing if I change manufacturers?
The listing is filed by the responsible person, which is usually your brand, and it identifies the facility that makes the product. Moving production means updating the listing, and the new factory needs its own FDA facility registration.
