PatentSino IP Firm

Established in 2012, PatentSino is a full-service IP law firm based in Beijing, with branch offices in Hefei, Xi’an and Dalian. The firm has more than 200 staff members in total, including 124 patent attorneys and patent engineers, and nine trademark attorneys. All of our partners have been working in the IP field for more than 15 years and have extensive experience in patent prosecution and related professional services in China and abroad. The majority of our patent attorneys hold doctorate or master’s degrees and have overseas education experience. Our team can also work in numerous languages, including English, Japanese, German, French and Korean. Our aim is to provide high-quality IP services to our domestic and international clients.

We provide the full spectrum of IP services relating to the prosecution and litigation of patents, freedom-to-operate analysis, trademarks, copyright and domain names. Our professional team covers all technical fields, such as chemicals, biotechnology, pharmaceuticals, materials, mechanical, medical devices, automotive, semiconductors, optics, aviation, electrical and telecommunications.

We serve a diverse range of domestic and international corporations and individuals, including start-ups, well-known domestic entities, universities and Fortune 500 multinationals. Over the years, we have successfully assisted our clients in filing a large number of patent applications in China and abroad.

We are one of the few Chinese law firms to have created their own IP electronic system and software database. Our system is designed to manage our cases and record clients’ information and needs. What’s more, the system is connected with the e-filing system of the China Patent Office, which makes capturing information and downloading documents from the patent office seamless.

Teamwork, technical and interdisciplinary exchange, as well as constant training of our staff, guarantee the quality of our services and the success of our clients.

Our motto: “High quality is the key factor for the success of the firm and our clients.”
