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 has 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.

Trademark, copyright and domain name prosecution and litigation

Our trademark team consists of over 100 professionals, including expert trademark attorneys, paralegals and litigators. We are also equipped with an in-house investigation team to support the litigators in evidence collection across China.

We file over 10,000 trademark applications every year. Our attorneys have rich experience in providing comprehensive pre-filing strategies for our clients’ new filings. We conduct identical searches before filing trademark applications and provide proper countermeasures when any highly similar prior mark exists. We also advise on the goods/services description so that they are in full compliance with Chinese practice. As a result, we help our clients increase the success rate for registration and reduce the time and costs for unnecessary procedures.

Patent prosecution and litigation

We file over 20,000 patent applications (including inventions, utility models and designs) 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.

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 from the analysis of target patents to invalidation proceedings. We frequently represent clients before the different levels of courts or administrative authorities, assisting clients with the effective enforcement of their IP rights or in defending them against third-party claims.


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.

In June 2020 we set up our 11th branch office, which also specialises in IP services, in Zhaoqing, Guangdong Province.

Quality management system

Jiaquan established the GB/T 19001-2016/ISO 9001:2015 Quality Management System and obtained the Quality Management System Certificate of Conformity in May 2020.

The said certified quality management system covers the firm’s main service areas, such as IP law services (domestic and foreign patents, trademarks and software copyright), enterprise management consultancy services, legal consultancy services, science and technology project agency services.

During the lockdown in China in early 2020, our up-to-date system assisted our team (working from home) in creating more efficiency and flexibility in our services.
