Intellectual property when somebody else builds your product

Separating what you brought from what the work creates

Two categories behave differently. There is the material each side already owned before the relationship, such as your design and their process technology, and there is whatever the collaboration generates: a tooling solution, a jig, a firmware fix, a process route, an improved geometry. Arrangements that address only the first leave the second unallocated, and unallocated things tend to be claimed by whoever is holding them when a disagreement starts. Ownership, the right to use, and the right to register are distinguishable, and it is entirely normal for a manufacturer to retain rights in its own process while you retain rights in the product. Have advisers settle which is which.

Registered rights are national, and timing matters

Patents, registered designs and trade marks are granted country by country by national and regional offices, and holding one somewhere does not automatically give you anything elsewhere. That is directly relevant when production moves to a country where you have registered nothing, because the practical remedies available there depend on what exists there. Whether disclosure to a manufacturer affects your ability to register later, and in which markets you should be filing at all, are questions for a qualified attorney, and they are best asked before the design pack is issued rather than after a product has been in a factory for a year.

What actually crosses the boundary, and how far it travels

Map the disclosure honestly. Beyond drawings and models there are material specifications, supplier names, test limits and the reasoning behind them, packaging artwork, firmware, and the tooling that embodies your geometry more completely than any document. Much of it continues onward: a mould shop, a plating house, a printer and a test-fixture builder may each receive a slice. Each additional recipient is a place where control weakens and a place where obligations have to be passed down. Knowing who holds what is the precondition for both confidentiality management and any later attempt to establish that something was taken.

Improvements that come off the floor

Manufacturers improve the things they build. A production engineer alters a gate position, redesigns a fixture, finds a cure profile that halves scrap, or suggests a geometry change that solves an assembly problem. These contributions are valuable, and treating every one as your property by default is both unrealistic and a good way to stop receiving them. The workable arrangements distinguish improvements specific to your product from generic process advances the shop applies to all its customers, and they say who may use what afterwards. Agree the principle early, while nobody yet knows which ideas will turn out to be worth arguing over.

Structure protects better than clauses do

Pursuing a claim in an unfamiliar jurisdiction is slow, expensive and uncertain, so the sensible posture is to reduce what a copy would be worth. Keep a differentiating step in-house where one exists, whether that is final calibration, firmware loading, a proprietary component or a formulation blended elsewhere. Split work so that no single site holds the complete picture. Retain control of the brand, the channel and the customer relationship, which are usually harder to replicate than the article itself. Contractual protection still matters and should be drafted properly, but it is a remedy after the event, and structure is what makes the event less attractive.

Frequently asked questions

Should we file for protection before sending drawings to a factory?

Put that question to an attorney before the pack goes out, because the interaction between disclosure and later registration depends on the type of right and the country, and getting the order wrong can be difficult to undo. What you can do without advice is stage the disclosure so that early candidates receive only what quoting requires, and keep a dated record of what was sent to whom. That record is useful whatever route your advisers eventually recommend.

How do we protect a formulation or a process recipe that cannot be registered?

Compartmentalise rather than rely on paper alone. Blend or pre-mix the differentiating element yourself and supply it as a controlled input, disclose parameters only to the people who need them, avoid putting the full method in a single document that circulates, and split steps across sites where the process allows. Confidentiality terms remain worth having and should be drafted with legal help, but the practical protection comes from nobody in the building holding the complete recipe.

What should we do if we suspect our product is being made for someone else?

Gather evidence before raising it: samples, packaging, listings, photographs, dates, and anything indicating the source, including tooling markings and cavity identifiers if your parts carry them. Then take advice on options in the relevant country, since what is available varies and the commercial route may be quicker than the legal one. Handle the supplier conversation carefully, because an accusation made early and wrongly damages a relationship you may still depend on for supply.
