Patent and Design Strategy in China
Patent strategy begins before disclosure and separates invention, utility model, design and trade secret. Add ownership and freedom-to-operate work: patentability asks whether you may obtain a right; FTO asks whether commercial acts may fall within enforceable third-party claims.
First job Separate patentable subject-matter from trademarks and from what must stay a secret.

Key considerations
The first questions are about urgency, governance and preservation — before collection expands or interviews begin.
- Is the subject patentable, or must it stay confidential?
- Invention, utility model, or design?
- Has it been disclosed already?
Direct answer
What this page decides
02
A China patent project starts before public disclosure. Separate the protectable subject matter into technical inventions, product structures and visual designs; then decide what should instead remain confidential. Invention patents receive substantive examination and can protect products or processes. Utility models protect qualifying product shape or structure and can provide a faster, narrower layer, but they are not a substitute for well-drafted invention claims. Design patents protect the visual design of a product, including qualifying partial designs, rather than its technical function. Confirm the applicant, inventors or designers, service-invention position and assignment chain before filing. For inventions or utility models substantially completed in China, address the statutory confidentiality examination before filing abroad. Preserve priority dates, draft for the intended commercial embodiments and competitors' likely design-arounds, and keep patentability separate from freedom to operate: obtaining a patent does not establish that the product avoids third-party rights.
At a glance
Which fact changes the next route
Use the fact that changes ownership or urgency to decide the next move.
| Question | Why it matters | Next route |
|---|---|---|
| Has anything been disclosed? | Sales, exhibitions, publications, investor decks, repositories and supplier discussions may affect novelty, and statutory exceptions are limited. | Freeze non-confidential disclosure and create a dated disclosure record before deciding the filing path. |
| Which right fits the subject matter? | Inventions, utility models and designs protect different things and follow different examination paths. | Map technical function, product structure, appearance and know-how into separate protection candidates. |
| Who owns the filing? | Employment duties, employer resources, commissioned work, collaboration and assignments can change ownership and remuneration obligations. | Resolve applicant, inventor or designer and chain of title before priority deadlines. |
| Was the invention completed in China? | An invention or utility model completed in China may require confidentiality examination before a foreign filing. | Determine where the substantive technical solution was completed and sequence foreign filings accordingly. |
| Can the product be launched? | Patentability and freedom to operate answer different questions. | Run product-, territory- and date-specific claim analysis before the commercial launch decision. |

Practical workflow
Action, evidence, legal gate, output
| Action | Documents / evidence | Legal gate | Output |
|---|---|---|---|
| Capture the invention and disclosure history | Technical description, drawings, prototypes, repositories, meeting records, publications, offers, sales, exhibitions and confidentiality terms | Identify novelty risk and the last safe filing date | Dated invention and disclosure record |
| Resolve people and ownership | Inventor contributions, employment duties, employer resources, commission, collaboration, funding and assignment terms | Distinguish creative contribution from supervision and administrative support | Inventorship, applicant and title matrix |
| Choose protection instruments | Technical functions, product structures, manufacturing methods, user-visible appearance, lifecycle and reverse-engineering risk | Allocate subject matter among invention, utility model, design and trade secret | Layered protection plan |
| Plan territories and priority | China activity, foreign markets, first filing, Paris or PCT route, priority documents and confidentiality-examination facts | Sequence China and foreign filings without losing priority or breaching the China confidentiality rule | Filing calendar and jurisdiction map |
| Draft around the commercial objective | Core embodiment, alternatives, fallback positions, experiments, data, drawings, interfaces and competitor design-arounds | Support useful claim breadth and required disclosure at filing | Application-ready specification and claims or design views |
| File and prosecute | Request forms, applicant data, priority claim, translations, examination requests, office actions, amendments and interview records | Protect deadlines while avoiding unsupported amendment or accidental narrowing | Prosecution docket and decision record |
| Operate the granted portfolio | Grant, annual fees, assignments, licences, pledges, product mapping, marking, watch results and evidence | Keep ownership and legal status accurate and connect rights to actual products | Maintained and enforcement-ready portfolio |
Documents
What to gather before the next call
These items help clarify the file; they are not a legal requirement list.
| Item | Why needed | Who holds it | Risk if missing |
|---|---|---|---|
| Invention disclosure and contributor record | Preserves the technical contribution, chronology and inventorship evidence | R&D lead, contributors and patent counsel | Incomplete disclosure or incorrect inventors |
| Disclosure and confidentiality log | Tracks what was shown, to whom, when and under which restrictions | R&D, business development and legal | Novelty is lost before filing |
| Ownership and assignment file | Connects employer, commissioning party, collaborators and applicant | HR, corporate, procurement and legal | The applicant lacks a clean chain of title |
| Filing and priority calendar | Controls first filing, foreign filings, PCT entry, examination and response deadlines | Portfolio manager and agents | Priority or application rights lapse |
| Specification, claims and drawing archive | Preserves filed text, translations, amendments and design views | Inventors, designers and patent counsel | The granted scope no longer matches the product |
| Product-to-claim and legal-status map | Supports maintenance, licensing, diligence and enforcement decisions | Product, finance and IP teams | Fees are paid on irrelevant rights while key products remain uncovered |
Common failure points
Where files usually break
Publishing, selling, exhibiting or sending an unrestricted supplier pack before the filing decision is executed.
Naming a manager or executive as inventor because of title while omitting the people who made creative contributions.
Assuming the employer owns every invention without reviewing duties, resources, commission terms and service-invention rules.
Filing abroad first for an invention substantially completed in China without addressing confidentiality examination.
Using a utility model as if it protected a process, or a design patent as if it protected technical function.
Drafting only the preferred prototype and leaving no supported fallback positions or commercially relevant variants.
Treating a patentability search or granted patent as freedom to operate against third-party claims.
Missing substantive-examination, response, priority, national-phase or annual-fee deadlines.
Requesting priority examination without checking current eligibility, evidence and the 2026 procedural rules.
Maintaining a large portfolio without mapping live claims and designs to products, markets and enforcement value.
FAQ
Narrow follow-ups owned by this page
Should an invention and utility model be filed together?
Sometimes parallel filings are useful, but subject matter, timing, double-patenting rules, expected examination and commercial value must be coordinated. It is not an automatic default.
Can software or AI be patented in China?
A claim is assessed as a whole under the current Guidelines. A patent application must present qualifying technical subject matter and satisfy novelty, inventiveness and disclosure requirements; an algorithm or business rule in isolation is not enough.
Does an NDA preserve patent novelty?
Confidentiality can help prevent a communication from becoming public, but the facts and agreement matter. It does not repair every prior disclosure or extend statutory priority deadlines.
Does priority examination guarantee grant?
No. It changes examination timing only when current eligibility and procedure are satisfied. Patentability standards and the examiner's substantive assessment remain.
How long do the rights last?
Subject to the governing filing date, payment and other statutory rules, invention patents generally run 20 years, utility models 10 years and designs 15 years from filing. Term compensation may require separate analysis.
Decision map
Keep the question bounded.
- Choose patent or secrecyAssess reverse-engineering risk, useful life, detectability, disclosure and enforcement. Keep confidential subject matter controlled until the filing decision is executed.
- Resolve service-invention ownershipMap employee duties, employer resources, inventorship, commission and collaboration terms, assignments and inventor reward or remuneration obligations.
- Build the filing stackCompare invention, utility-model and design protection, priority deadlines, claim scope, drawings and parallel filings; do not use a design filing as a substitute for technical claims.
- Run product-specific FTODefine product, features, process, territory and launch date; search relevant families, construe live claims, check legal status and record design-around, licence or challenge decisions.
