Chang Tsi & Partners provides full-cycle legal services for integrated circuit layout-design (ICLD) protection, serving IC design enterprises, semiconductor research institutions, and individual designers across Mainland China, Hong Kong SAR, Macao SAR, and Taiwan. Drawing on both our patent agency qualification and law firm credentials, we handle ICLD registration applications and related follow-up matters, and provide comprehensive support in dispute resolution, litigation, and legal advisory.
ICLD protection operates under a distinct legal framework separate from the patent system, with its own examination standards—registration requires the applicant to demonstrate that the layout-design is the product of their own intellectual effort and possesses originality; moreover, the application must be filed within two years of first commercial exploitation or the right to register is forfeited. In dispute resolution, cancellation proceedings draw on our patent agency qualification while civil and administrative litigation rely on our law firm credentials, enabling seamless legal support from administrative rights confirmation through judicial remedies.
At the rights acquisition stage, we provide full-process agency services for ICLD registration applications and related follow-up matters, together with legally-led search and assessment services, helping clients establish effective IP protection from the chip R&D stage.
In ICLD dispute resolution, cancellation proceedings draw on our patent agency qualification, while civil litigation, administrative litigation, and administrative complaints rely on our law firm credentials. The combination of both qualifications enables us to provide seamless legal support—from administrative rights confirmation through judicial remedies.
We assist clients in realising the commercial value of their ICLD exclusive rights through licence agreement drafting and negotiation, assignment transaction support, and infringement dispute settlement.
