Who owns the process sheet when the customer owns the mold?
By SourceX Editorial · Reviewed by Noah Loul ·
Short answer
Who owns injection molding process parameters is usually decided by contract, not by who owns the mold. Paying for the steel gives the customer title to the tool, but process sheets, setup data and cavity pressure profiles are typically created by the molder. Unless the tooling agreement or PO terms say otherwise, the molder may have a strong claim.
Key takeaways
- Owning the mold and owning the process knowledge are separate questions, and contracts often treat them differently.
- Customer purchase order terms sometimes claim setup data or tooling documentation, so read the fine print, not just the tooling quote.
- Copyright in a process sheet written by employees generally belongs to the employer, but the settings on it are better protected as confidential information or trade secrets.
- Trade secret protection depends on reasonable secrecy measures, so process sheets need access controls and confidentiality terms.
- Agree on what travels with a mold at transfer before the first tool is built.
Who owns the process sheet?#
The process sheet's owner is decided mainly by the contracts between molder and customer, and owning the mold does not by itself transfer the process. A customer that pays for a mold typically takes title to the steel, inserts and sometimes the mold design; the process window your engineers developed on your presses is a different asset.
Disputes arise because the documents rarely say this clearly. A tooling quote may cover the mold, the customer's purchase order terms may claim all documentation related to tooling, and a quality agreement may require a validated process to be documented and shared. Reading all three together is the only way to answer the question for a given part.
Ownership by item: mold, design, process and logs#
Ownership in a molding relationship splits item by item, and the deciding document differs for each one. The table shows common patterns, which counsel should confirm against your actual agreements.
A pattern runs through the table: the physical tool follows payment, while knowledge generated on the molder's presses follows the paperwork. Where the paperwork is silent, the molder's position generally rests on confidentiality and trade secret principles rather than on title.
| Item | Usual owner | What decides it |
|---|---|---|
| Mold steel, inserts and components | Customer, once tooling is paid for | Tooling quote, tooling PO, title transfer and acceptance terms |
| Mold design and CAD files | Varies; often the toolmaker unless purchased | Tooling agreement, toolmaker terms, design deliverable clauses |
| Part design and drawings | Customer | Customer drawings, NDA and supply agreement |
| Process sheet and setup parameters | Often the molder, unless a contract transfers it | PO terms, quality agreement, tooling agreement, transfer clauses |
| Cavity pressure profiles and monitoring data | Usually the molder, generated on its equipment | Data and confidentiality clauses, validation deliverables |
| DOE studies and validation reports | Negotiated; often delivered as part of validation | Quality agreement, PPAP or validation requirements |
| Mold maintenance log | Often shared; the molder keeps its own records | Maintenance and transfer terms in the tooling agreement |
Which documents decide it?#
The documents that decide process sheet ownership are spread across the quoting, purchasing and quality stages of a program. Collect them for each customer before taking a position.
Order of precedence clauses matter. When PO terms and a negotiated supply agreement conflict, the agreement usually says which one wins; where no agreement exists, the PO terms may govern by default, including terms incorporated by a link you never opened.
Look at past practice as well. If the molder has handed over full process packages on earlier transfers without objection, a customer may argue that the practice shows what the parties intended. Handling transfers consistently supports whichever position the contracts take.
- RFQ and quote terms, including any conditions attached to your tooling quote.
- The customer's purchase order terms and conditions, often incorporated by reference to a website.
- Tooling agreements or tooling purchase orders, with title, maintenance and removal clauses.
- Supply or master purchase agreements, with intellectual property and confidentiality sections.
- Quality agreements and PPAP or validation requirements that list deliverables.
- NDAs signed at the start of the relationship.
Copyright, trade secrets and contracts: three different questions#
Copyright, trade secret law and contract rights answer different questions about a process sheet. Copyright covers the written document as an expression: under US law, for a work made for hire the employer is considered the author and owns the copyright unless the parties have agreed otherwise in a signed written instrument, so sheets written by your engineers in the course of their jobs start out as the company's.
The parameters themselves, such as melt temperature, injection speed, hold pressure and cooling time, are settings and facts that copyright generally does not protect. Their protection usually comes from contracts and from trade secret law.
Trade secret protection has conditions. Under the Defend Trade Secrets Act, information qualifies only if its owner has taken reasonable measures to keep it secret and it derives independent economic value from not being generally known. Process sheets taped to presses, left in unlocked folders and emailed freely to customers make that argument harder to win.
What travels with the mold at transfer?#
What travels with a mold at transfer is the most practical form of the ownership question. When a customer moves a mold to another molder, it usually wants enough information to restart production without a full requalification.
Molders often handle this in tiers. A basic setup sheet with starting parameters and the latest maintenance record goes with the tool. Full DOE studies, cavity pressure data, process development notes and scrap analyses stay with the molder unless the agreements require them or the customer pays for them.
Write the transfer package into the tooling agreement when the program starts. Negotiating what leaves with a mold during a dispute is much harder than agreeing on it when the mold is ordered.
Illustrative: a medical molder answers a transfer request#
Illustrative: a fictional molder runs customer-owned molds for a medical device company. The customer decides to move one program to a second source and asks for every process document, including DOE studies, cavity pressure profiles and scrap analyses.
Counsel reviews the paperwork. The tooling purchase order transfers title to the mold only. The quality agreement requires a validated process and lists the validation report as a deliverable, which the molder already supplied. The PO terms say nothing about process data. The molder releases the mold, its latest maintenance record and a setup sheet, points to the delivered validation report, and keeps its DOE studies and pressure data as confidential information. The customer accepts after a call between the two quality teams.
What this means for licensing process data#
Licensing process data depends on the same analysis. If a molder wants to license de-identified process histories, scrap records and maintenance logs to AI developers, the rights review must first confirm those records are the molder's to license under each customer's terms.
SourceX runs that review in the Rights step of the SourceX five-step transaction, before any preparation. Customer part geometry, drawings and names are excluded, records tied to restrictive customer terms are carved out, and a SourceX Evidence Packet records which agreements were reviewed and what the molder authorized for release.
Licensing also tests secrecy measures. A molder that licenses process histories should do so under confidentiality terms and permitted-use limits, so the license itself does not weaken trade secret protection for the underlying know-how.
Frequently asked questions
Does paying for the mold design mean the customer owns the process?
Not automatically. Paying for a mold design gives the customer whatever the tooling agreement says it buys, often the design files. The process window is developed later on the molder's presses. Unless a contract transfers it, the process is a separate item that counsel should assess on its own.
Can a customer demand our process sheets under its PO terms?
It may, if its terms say so and those terms govern the relationship. Some customer terms define tooling to include related documentation or data. Check whether your quote terms objected, whether a supply agreement overrides the PO, and how the order of precedence clause resolves conflicts.
Should we mark process sheets as confidential?
Marking helps. Labels, access controls and confidentiality terms in customer agreements support the reasonable secrecy measures that trade secret protection requires. Marks alone are not enough if sheets are shared freely, so pair them with need-to-know access and a record of who received copies.
What should a new tooling agreement say about process data?
It should list what the customer buys, such as the mold and specific design files, and what the molder keeps, such as process development data. It should define the transfer package, who pays for extra documentation, and how long confidentiality lasts after a mold leaves the plant.
Do these rules change for automotive PPAP work?
The documents change, not the principle. PPAP submissions require specific process documentation, so whatever is in the approved submission goes to the customer. Process knowledge beyond those deliverables still depends on the supply agreement, the PO terms and the customer's quality requirements.
