Liu Shen & Associates

Established in March 1993, Liu Shen & Associates is a patent and trademark agency designated by the Chinese government to deal with patent and trademark affairs involving overseas parties; it is also registered at the Ministry of Justice. As a three-in-one firm, Liu Shen & Associates has the capability to serve its clients in all phases of intellectual property, including the acquisition of rights, the transfer and licensing of rights, the investment of rights, enforcement and protection of rights, and related litigation and administrative proceedings.

The practice of the firm mainly focuses on filing and prosecution patent applications and registration of trademarks on behalf of foreign clients. The firm also handles IP law-related litigations, licensing and transfer of technology, joint ventures, e-commerce and related trial and appellate litigation, as well as dispute resolution before administrative authorities.

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 majors. All of the firm’s professionals are at least bilingual. The high-quality service has won the firm trust from many well-known corporations in the world, who become longstanding clients and business partners as a result.

The firm has 51 partners, 190 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 our 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.
