Employee Inventions in China: Build an Ownership File Before Enforcement

By Pan Jianxing · Published 27 October 2026

A foreign business planning to enforce a Chinese patent may find that an engineer, its local subsidiary or a development contractor appears in the early records. Before sending an allegation in the parent company’s name, determine how the invention was created and how the asserted rights reached that company.

The inventor’s identity and ownership of the application or patent are different questions. A signature on an invention disclosure, an employment contract and a patent registration each address part of the history. None should be read in isolation as proof of every link.

Classify the development relationship

Article 6 of the Patent Law as amended in 2020 addresses inventions made in performing the entity’s tasks or mainly using its material and technical resources. For a service invention, the right to apply belongs to the entity; after grant, that entity is the patentee.

For a non-service invention, the application right belongs to the inventor or designer. Article 6 also recognises an agreement on ownership where the invention was made using the entity’s material and technical resources. Review the actual contractual provision alongside the statutory category; do not assume every employment clause has the same effect in every factual situation.

Identify the entity that employed or engaged the relevant person and the entity that assigned the work. A parent and subsidiary should not be treated as interchangeable owners. If the work was commissioned from an outside contractor, Article 8 provides a separate starting point: absent a different agreement, application rights belong to the party completing the invention. Paying the development invoice does not by itself settle ownership.

Connect duties to the technical contribution

Article 13 of the 2023 Implementing Regulations covers inventions made in ordinary job duties and in performing additional tasks assigned by the entity. Obtain job descriptions, project instructions, meeting records and contemporaneous technical work. A job title alone may be too general to explain what a person was required to develop.

Prepare a dated account of the technical problem, proposed solution, trials and revisions. Link those events to the invention described in the application. Retain laboratory notes, design versions, source repositories where relevant, test results and submission records in their original form. Record who maintained each system and how the material was exported.

Article 14 defines an inventor or designer by a creative contribution to the invention’s substantive features. Merely organising the project, facilitating resources or providing auxiliary work does not establish inventorship. Use contribution records to distinguish substantive development from project management, without assuming that managerial seniority determines who must be named.

Review resources and departure dates carefully

The Regulations identify resources including funds, equipment, components, raw materials and non-public technical information. Assemble evidence of what was actually used and its role in completing the invention. Avoid reducing the analysis to whether work happened at home or outside office hours.

Article 13 also includes inventions made within one year after retirement, transfer away from the original entity or termination of the employment or personnel relationship, where they relate to the person’s original duties or assigned tasks. Both the timing and the relationship to that work matter. The provision does not make every invention following a departure automatically belong to the former employer.

Keep the departure record, the technical development chronology and the patent filing chronology separate. The filing date may be relevant evidence, but it is not automatically the date the invention was made. Where a former employer’s confidential information may be involved, obtain it only through lawful channels and assess confidentiality issues separately.

Trace the rights to the proposed claimant

Compare the development analysis with the current Chinese register, the original application and every intervening assignment. Article 10 requires a written transfer contract and registration, with transfer taking effect on registration. It also requires the applicable procedures for transfers by Chinese entities or individuals to foreign recipients.

If the foreign parent is intended to enforce rights initially belonging to its Chinese subsidiary, locate the actual transfer and registration evidence rather than relying on group ownership. If ownership is disputed or records are inconsistent, identify the issue for resolution before presenting an unqualified ownership assertion to a court or platform.

Keep inventor attribution and compensation on the review list. Article 16 addresses naming the inventor in patent documents, while Article 15 addresses rewards and reasonable remuneration for service inventions. These matters should be assessed under the applicable rules and agreements; the ownership review should not assume they disappear merely because the entity holds the patent.

Prepare a concise ownership dossier

A useful dossier contains a relationship chart, development chronology, task and resource evidence, contribution table, relevant agreements and current registration records. Mark unresolved facts explicitly and preserve contrary evidence rather than editing it out of the narrative.

Contact Pan Jianxing with a non-confidential description of the development arrangement and the Chinese patent number. Establishing who owns the enforceable right helps determine the proper claimant and which missing records should be addressed before an enforcement step.
