Jiaquan IP Law

Jiaquan IP Law is one of China’s most renowned IP law firms. Founded in 1988, our firm has gradually developed from a patent legal service provider into a full-service IP law firm specialising in the broader fields of IP filing, prosecution and transaction. Our many years of practice have given us an in-depth understanding of the enforceability of patent rights, while our rich experience in patent enforcement guides us through patent claim drafting.

Over 30 years, Jiaquan has expanded to a total of 11 offices across China, including in Beijing, Hunan and Guangdong, with our head office in Guangzhou and a team of over 800 professionals covering all technical backgrounds. We have worked with business partners in over 100 countries in the world. We tailor specialised IP strategies to suit our clients’ unique needs and have a solid track record of thousands of successful cases.

Patent drafting and prosecution

Patent drafting and prosecution is one of our key practice areas. We file over 30,000 patent applications (including invention, utility model and design) every year. Our team of over 420 patent attorneys and patent engineers includes 14 former patent examiners and 15 professionals qualified as both patent attorneys and attorneys at law. Many of our attorneys hold advanced degrees in their technical fields and/or have worked in the industry. The technologies at issue span nearly every industry sector, including electronics, mechanicals, chemicals, pharmaceuticals, medical devices, biotechnology, automation, computer software and information technology. Besides, we set up a quality control board headed by two lead attorneys (former patent examiners) to supervise drafting of important patent specifications.

Patent invalidation and litigation

Jiaquan is listed as one of the 2019 Top 10 IP Agents for Civil Patent Litigations in China. Our litigation team consists of 30 attorneys at law, one nominated IP infringement judgment expert and one former judge. We handle nearly 300 patent litigations and invalidations every year. Our team has comprehensive experience in invalidation proceedings before the China National Intellectual Property Administration and assists our clients all the way from analysis of target patents to invalidation proceedings. We frequently represent clients before different level of courts or administrative authorities, assisting clients with the effective enforcement of their IP rights or in defending them against third-party claims. Our attorneys have extensive experience representing patentees and defending against patent infringement claims in patent litigation cases.

Patent searches

Our patent search team consists of three former patent examiners and eight experienced patent attorneys. Our team has technically prevailed in a national patent searching competition in 2018. We provide almost all kinds of patent search and analysis, including patentability, infringement/non infringement, freedom to operate, landscape and validity. We can also provide flexible workflows to meet our clients’ expectation – for example, mid-term report, teleconference before a formal report is issued, brief conclusion instead of a formal report. Our attorneys speak several languages and have extensive knowledge of IP rights prosecution and infringement case law, which enables them to provide comprehensive analysis to different clients in different sectors.

In early 2019 we established a law firm in Guangzhou to cover other legal services besides intellectual property. This means that Jiaquan is now a full-service law firm covering the entire legal needs of its clients.
