Liu Shen & Associates

Established in March 1993, Liu Shen & Associates is a leading law firm in China focusing intensively on patent and trademark procurement, strategic counselling on all aspects of intellectual property and enforcement of IP rights including litigation.

The strength of Liu Shen & Associates is built on the quality and expertise of its people in the area of intellectual property and related laws and practices. Most of our partners have been leading practitioners in the area for more than two decades, while the majority of our professionals have advanced degrees in various subjects. All of the firm’s professionals are at least bilingual. The firm’s high-quality service has won the trust of many well-known corporations around the world, which have become longstanding clients and business partners as a result.

The firm has 60 partners, 200 patent attorneys, 70 attorneys at law (most of whom are also qualified as patent attorneys) and 11 trademark agents. Most partners of the firm are active in professional organisations, such as the All China Patent Agent Association (ACPAA), the International Association for the Protection of Intellectual Property and the International Federation of Intellectual Property Attorneys. The general managing partner, Perry W Yang, is the president of the ACPAA.

Patent and trademark filing and prosecution

Liu Shen & Associates has extensive expertise in filing and prosecuting patent and trademark applications.

The firm has a distinguished and committed team consisting of competent patent and trademark attorneys, experienced former examiners of the Chinese Patent Office and highly trained administrative staff. Team members not only possess solid technical and legal backgrounds, but also have a good command of foreign languages. In addition to English language capabilities, Liu Shen & Associates has a Japanese language group of 46 members and a German language group of 24 members, whose patent attorneys and patent engineers can deal with documents in Japanese and German efficiently. Due to their active engagement in patent applications relating to innovative technologies such as computer software, nanotechnology, genetic engineering and e-business, the patent attorneys of Liu Shen & Associates have accumulated extensive experience in handling legal and technical issues in patent applications for new technologies.

Legal counselling and litigation

Liu Shen & Associates has high standing in the area of IP litigation, as was clearly shown by its ranking in the Managing Intellectual Property 2007 and 2008 surveys as the only first-tier law firm for contentious patent work, including all other patent-related legal work (eg, administrative enforcement and licensing). With experience working at both patent and trademark agencies and IP law firms, our highly experienced IP litigation attorneys have handled many legal disputes and patent, trademark, copyright and unfair competition cases. Two cases won by the firm were named as representative IP litigation cases by the Supreme People’s Court of China and one was named as one of the 10 most significant IP cases of the past 10 years by the Beijing Higher People’s Court. In addition, Liu Shen & Associates received a silver medal from a multinational company for its outstanding achievements in IP protection.
