Yan Jing — Intellectual Property Lawyer in Xi'an

Her representative matters include software copyright disputes, copyright and unfair-competition litigation involving technology companies, trademark projects and ongoing counsel to medical-technology and public-sector clients. Software disputes require a different evidentiary approach from ordinary trademark litigation. A claimant may need to establish ownership of source code, the development history of specific modules, employee or contractor authorship, the defendant's access opportunity, similarity between code bases and the relationship between copyright protection and confidential technical information.

That overlap is central to Yan's practice profile. If a departing engineer copies source code and joins a competitor, the former employer may consider several legal theories. Software copyright can protect original expression in the computer program and related documentation. Trade-secret law can protect non-public technical information that has commercial value and is subject to corresponding confidentiality measures. The Anti-Unfair Competition Law may also address misappropriation and related competitive conduct. The strongest claim depends on what was taken, how the company protected it, and what the competitor actually used.

The distinction matters because the evidence for each claim is different. Copyright ownership may be supported by development records, employment agreements, source-code repositories and software registrations. A trade-secret claim requires the rights holder to define the secret with sufficient specificity and show that it was non-public, valuable and protected by confidentiality measures. An unfair-competition theory cannot be used as a vague substitute when the company has not identified the underlying conduct.

Yan's advisory work on IP management is therefore highly relevant to litigation readiness. A company that cannot tell which employees had access to a particular repository or which modules were developed by contractors may face difficulty after a defection. Effective IP management should include ownership documentation, role-based access, repository logs, confidentiality classifications, contractor assignments, exit procedures and incident-response controls.

Her labor-compliance experience is also useful in employee-driven IP disputes. The company may discover suspicious downloads shortly before resignation and want to inspect devices, suspend access or enforce a non-compete. These actions need to be coordinated with Chinese employment and personal-information rules. A technically strong IP case can be undermined if evidence is collected unlawfully or if the employer destroys original data while trying to investigate.

Yan's profile also includes trademark and brand strategy. This broadens her relevance for technology companies commercializing products under valuable brands. A startup may focus on patents and software while neglecting ownership of trademarks, domain names or application-store accounts. In a financing, acquisition or dispute, those assets can become important. Her practice therefore covers both the technical and commercial sides of IP protection.

Her work as an invited mediator and professional participant in IP-related organizations further aligns with dispute resolution. IP disputes often benefit from carefully structured settlement because the parties may continue to operate in the same industry. A settlement may require deletion or return of source code, restrictions on use, coexistence terms, damages, audit rights or technical verification. Litigation strategy should therefore be designed around the commercial remedy the client actually needs.

For software and technology companies, Yan's combination of IP litigation and employment-adjacent compliance is particularly useful during employee exits. The legal team may need to preserve devices and repository logs, suspend credentials, determine whether the employee remains subject to confidentiality or non-compete obligations, and decide whether a court application should be pursued before copied information is disseminated more widely. Those decisions have to be made quickly, but they also need to be proportionate and evidence-based.

Technology companies also face ownership problems that predate any dispute. Code may have been written by founders before incorporation, outside contractors, university researchers or employees working across affiliated entities. A later infringement claim is much stronger when the company can establish a clean chain of title for the relevant code and documentation. Yan's software-copyright practice makes this ownership work a natural part of preventive IP management.

Her unfair-competition practice is equally relevant when the defendant's conduct cannot be reduced to literal code copying. A competitor may recruit a team, reproduce product architecture, imitate documentation, misuse non-public commercial information or combine several forms of conduct. Counsel must decide which facts support copyright, trade-secret, trademark or unfair-competition theories and avoid overpleading claims that dilute the strongest evidence.

For multinational technology companies, English-language capability can also matter in evidence collection and reporting. Source-code ownership, internal investigation findings and litigation strategy may need to be explained to overseas headquarters, investors or insurers. A local lawyer who can connect Chinese litigation requirements with the company's technical records can make those communications more useful.
