Cheng & Peng Intellectual Property Law Office has been recognized in the 2026 edition of the IAM Patent 1000, receiving Bronze Firm rankings in both Prosecution and Litigation for Mainland China. The firm is one of only a select group of Chinese boutique practices to secure international recognition across both the prosecution and contentious sides of the patent landscape.
In addition, three partners were individually recommended. Founding partner Miao Cheng received a Silver ranking for Patent Litigation, while partners Peng Wu and Guangming Liu were each named with a Bronze ranking for Patent Prosecution. Having three experts from the same firm listed in a single year underscores the depth of technical and legal expertise across the practice.
Miao Cheng has spent over twenty years at the forefront of patent dispute resolution in China. With a strong command of both U.S. and Chinese patent practice, he brings a rare combination of legal acumen and technical fluency — particularly in the life sciences, biotechnology, and chemistry sectors. He is widely recognised for crafting commercially sound litigation strategies that align legal outcomes with business objectives.
On the prosecution side, Peng Wu and Guangming Liu are active across the life sciences, automotive, and mechanical engineering fields. Both have substantial experience managing large-scale cross-border patent portfolios, invalidation proceedings, and FTO analyses, helping clients secure and defend valuable patent assets.
Published by the Globe Business Media Group, IAM (Intellectual Asset Management) is a leading global publication covering IP strategy, patent commercialisation, and litigation. Its Patent 1000 rankings are widely regarded as the gold standard in the industry, based on months of independent research across patent services in major jurisdictions. Criteria include case success rates, drafting quality, client feedback, and cross-border capabilities — ensuring that only the strongest firms in each category make the list.
Since its founding in 2013, Cheng & Peng has focused exclusively on high-end intellectual property services, developing deep expertise in complex patent litigation, cross-border portfolio strategy, and high-value transactions. The firm’s team is composed of top graduates from leading institutions including Tsinghua and Peking University — nearly 80% of its attorneys hold degrees from these two universities — with an average of 18 years of professional experience.
This blend of legal and technical depth enables the firm to deliver precise, commercially focused enforcement strategies that help clients navigate increasingly complex IP challenges across multiple jurisdictions.
The dual recognition in the IAM Patent 1000 — covering both firm and individual achievements — represents a significant endorsement of Cheng & Peng’s integrated service model by one of the industry’s most respected authorities. The firm will continue to invest in its full-service IP capabilities, providing clients with the legal and strategic support they need to protect, leverage, and grow their innovations.
