Team overview:
ZY Partners’ patent practice is anchored by a seasoned litigation and prosecution team comprising dual-qualified patent attorneys and trial lawyers with deep technical and legal expertise. The firm’s senior leadership includes Qiang Zhou, Jingbing Li, Hong Ai, Hui Zhang, and Xiaolin Huang, who each bring more than two decades of experience handling IP disputes across China’s courts and administrative tribunals.
Zhou is widely recognised for his courtroom advocacy and strategic approach to complex patent and trade secret cases, representing both Chinese innovators and international technology leaders. Li, who holds a PhD in law and co-founded the firm, provides strategic direction on high-stakes IP and regulatory matters. Ai and Zhang oversee the firm’s portfolio of litigation and enforcement work in the manufacturing and electronics sectors, while Huang, a senior partner with a technical background, specialises in patent examination, invalidation, and infringement disputes across semiconductors, telecoms, and life sciences.
Supporting the senior team is a technically diverse group of attorneys and patent agents, many of whom are dual-qualified in engineering and law. This technical depth allows ZY Partners to handle disputes and filings in sectors including electronics, telecommunications, semiconductors, mechanical engineering, renewable energy, pharmaceuticals, and biotechnology.
