Protecting a product means protecting several different things: its technical function, visual design, creative files, brand, confidential know-how, and the permission a factory receives to use them. Before you share sensitive material, identify which rights may apply, put ownership and use limits in writing, and restrict access in practice. An NDA is one layer—not a complete IP strategy.
Start by identifying what needs protection
Make an inventory before approaching factories. A product can contain multiple assets, and one form of protection will not necessarily cover them all. The European Commission’s IP overview and WIPO’s trade-secret guidance distinguish the following categories:
As an Amazon Associate I earn from qualifying purchases.
| Protection | Best suited to | Important limit or decision |
|---|---|---|
| Patent | A qualifying technical invention | Eligibility, filing and disclosure requirements, and territorial scope depend on the jurisdiction. |
| Registered design | A product’s visual appearance | Scope, novelty rules, filing procedure, and territorial coverage vary. |
| Copyright | Original creative expression, such as artwork or documentation | It generally protects the expression, not the underlying idea or function. |
| Trademark | Brand names, logos, and other signs that identify a source | It protects brand identity, not technical function or confidential processes. |
| Trade secret | Commercially valuable confidential information, such as process know-how | Protection depends on keeping the information secret through reasonable measures; it does not generally prevent independent development. |
| Contract or NDA | Confidentiality, permitted use, ownership allocation, and defined manufacturing permission | Its effect depends on the wording and applicable law; it does not replace registration or practical secrecy measures. |
For each asset, record what it is, who created it, who currently owns it, where it may be used, and which people or suppliers need access. Include technical specifications, drawings and CAD files, software, prototypes, brand identifiers, process know-how, and supplier or customer information. Ownership rules can vary, so retain dated creation records, assignments, and prior contractor agreements, and confirm that the correct legal entity owns the relevant rights.

Before contacting factories
Decide what must stay secret
Trade-secret protection is tied to secrecy, not simply to labeling something confidential. WIPO and the European Commission describe the key EU trade-secret criteria as commercial value because information is secret, lack of general knowledge or easy accessibility, and reasonable steps to keep it secret. Examples of those steps include marking sensitive material, limiting access to people with a need to know, reviewing access, using confidentiality agreements, and keeping records of disclosures.
#1 Best Overall
Use secure storage, limit file permissions, and keep a disclosure log. Share only what is needed at each stage: for example, an initial discussion may not require complete production files or unrelated customer and supplier details. Practical access controls support the contractual obligations you later put in place.
Check whether to file before disclosure
If patent or registered-design protection may matter, ask an IP professional or the relevant IP office in the countries that matter to you whether filing should occur before any public disclosure. Filing routes, eligibility, novelty rules, and deadlines are jurisdiction-specific; the sources cited here do not establish the rules for a particular country. Do not assume that a later filing will preserve rights after disclosure.
Before sending drawings, samples, or specifications
Agree confidentiality and permitted use in writing
Have a written NDA or confidentiality clause signed before sharing sensitive information. WIPO’s technology-transfer guidance recommends clearly identifying the protected information and the authorized use. Tailor the terms to the relationship rather than relying on a generic promise to “keep everything confidential.” Consider specifying:

- What information is covered, including verbal disclosures if relevant, and how it will be identified or confirmed.
- The permitted purpose—for example, evaluating or manufacturing the agreed product—and a prohibition on other use.
- Which employees, advisers, and subcontractors may receive the information, and what obligations they must have before access.
- The duration of confidentiality obligations, exceptions such as information already lawfully known or public, and how those exceptions are established.
- Required safeguards, incident notification, available remedies, and what happens to materials when the relationship ends.
Have local counsel review the wording and enforceability. A signature does not make an overbroad, unclear, or unenforceable clause effective.
Keep a record of each disclosure
Log what you sent, to whom, when, and under which signed terms. Keep copies of versions, emails, delivery records, and meeting notes. This documentation can help establish what was disclosed and the steps taken to maintain secrecy if a dispute arises.
Put ownership and manufacturing permission in the manufacturing agreement
Separate existing IP from new work
List each party’s pre-existing intellectual property, or background IP, and distinguish it from work created during the engagement, or foreground IP. Address drawings, software, tooling, molds, fixtures, improvements, and manufacturing-process changes specifically. A broad phrase such as “work product” may not clearly settle who owns each item or what either party may do with it.
State whether new work belongs to you, the manufacturer, or both, and whether an assignment is required. WIPO distinguishes an assignment, which transfers ownership, from a license, which grants permission to use IP under defined terms. Make the contract’s language match the intended result.

If the manufacturer needs permission to use your IP, define that permission narrowly: the product it covers, purpose, territory, term, production exclusivity if any, and which subcontractors may use the material. A right to manufacture your product should not silently become a broader right to sell, adapt, display, or use the files for other customers.
Address production leakage and control of physical assets
Write down how the parties will handle issues such as unauthorized overproduction, sale of seconds, use of designs for other customers, subcontracting, marketing or showroom display, and access to tooling and production files. Specify appropriate quality checks, inspection or audit rights, recordkeeping, incident notice, remedies, and end-of-engagement procedures. There is no universal clause set: tailor the controls to the product, manufacturing process, and applicable law.
Rank #4
WIPO’s guidance on collaborative innovation recommends a termination protocol. The agreement should say how the factory returns or verifies destruction of confidential files, samples, prototypes, and other materials, and what happens to tooling and production records.

Keep controls current
Review who has access as staff, subcontractors, and project needs change. Update third-party confidentiality obligations and permissions when the arrangement changes. Keep registration records and renewal dates with business records, and consider registering relevant rights in the markets where protection is needed. The appropriate filings, deadlines, and costs depend on the jurisdiction.
Respond promptly to suspected copying or disclosure
Preserve relevant files, messages, access logs, samples, and production records, and note when and how you learned of the issue. Seek advice from counsel in the relevant jurisdiction promptly. WIPO cautions that enforcement and proof requirements vary by country, and that trade-secret enforcement can be difficult.

Special care when manufacturing in China
The European Commission’s China IP SME Helpdesk published a contract guide in April 2012 that recommends confidentiality terms before disclosure and discusses NNN agreements—non-disclosure, non-use, and non-circumvention—for some China manufacturing and sourcing situations. It also warns that provisions may be unlawful or ineffective if drafted incorrectly. Because that guide dates from 2012, treat it as background rather than a statement of current law. Ask qualified China IP counsel to review the current rules, contracting entity, language, governing law, dispute forum, and execution formalities for your deal.
What an NDA can—and cannot—do
An NDA can help define confidential information and restrict the recipient’s use or disclosure according to the agreement and applicable law. It cannot by itself establish that you own every file or invention, secure registration-based rights, or replace sensible access controls. Nor do trade secrets generally stop someone from independently developing the same information; reverse engineering may also be lawful depending on the circumstances and local law.
As WIPO puts it in “How to Protect Trade Secrets?”: “The exact scope of behaviors you are protected against as a trade secret owner vary by country and by the contract you have in place with another party.” That is why protection should combine the rights suited to each asset, carefully drafted contracts, and day-to-day controls over what is shared.
