Firm Profile

LexField Law Offices, based in Beijing, provides a full spectrum of IP services. Our services include strategy counselling, prosecution, enforcement and litigation for trademarks, patents, copyright, domain names and unfair competition.

Our professionals have graduated from top-tier Chinese and overseas educational institutions. In addition to rich experience in the IP law field, many of us have industrial or commercial experience outside of the legal world. This diversity has contributed to the knowledge, insights and skills necessary to meet our clients’ varying needs.

We always serve our clients in a business-sensitive, result-orientated and cost-effective manner. Our clients include prestigious multinationals and Chinese companies across an array of industries, including telecommunications, automobiles, information technology, life sciences, consumer products, pharmaceuticals, energy and chemical engineering. They range from established market players to emerging newcomers. Such diversity leads to tailored services and we are proud of the value that we can add to our clients’ businesses.

Firm history

The firm was founded in 2004 by Jan Liu, a leading IP attorney in China, under the name Jan Liu & Associates, providing services in trademark, unfair competition and copyright matters. In 2009 the firm joined forces with a top-calibre litigation and patent prosecution team led by Hongyi Jiang. The firm then changed its name to LexField Law Offices and was able to provide a wider range of IP legal services to satisfy the growing needs of its clients.

Firm pride

The firm believes a key metric of its success is the satisfaction of its clients and, as a result, constantly strives to maintain a close relationship with the clients. Our unabated focus on clients’ objectives and satisfaction results in their deep trust and loyalty. This strategy has served the firm well in retaining clients, which include several Fortune 500 companies, and has been a major contributor in attracting new clients by word of mouth.

LexField’s professionals and practice groups have been recognised by the world’s most respected legal publications, receiving top rankings year after year.

Firm strength

Unrivalled trademarks practice

The firm’s trademark team, led by Ms Liu, is well known in the market for its high-quality service. Apart from its technical expertise, the team is highly responsive, provides tailor-made advice and understands the nuances of its clients’ businesses. As a result, the trademark team has been recognised by both our international clients and our Chinese peers.

The trademark team comprises over 40 trademark professionals, including attorneys at law and trademark agents. Clients include large multinationals, Fortune 500 companies and rapidly growing companies across diverse industry sectors. Applying trademark expertise across a wide range of businesses fosters tremendous innovative thinking and creativity as the team seeks to protect the interests of its clients.

Unsurpassed litigation practice

Many of the cases that the firm has handled have had widespread impact in China, setting new standards in IP law and establishing LexField as a leader in the IP litigation arena for both trademarks and patents.

Our litigation team has won over 30 IP retrials and retrial applications before the Supreme People’s Court in the past few years – more than any other firm. Retrial cases before the Supreme Court overturn judgments made by provincial higher people’s courts and are the most challenging in the Chinese legal system. The firm’s record clearly demonstrates that the team has the edge over competitors in the field.

Sophisticated prosecution and commercial IP practice

Collaborating closely with the litigation team, our prosecution and commercial IP teams are well equipped to help clients build and exploit their IP portfolio in a cost-effective manner and are ready for enforcement and litigation to provide a holistic solution. We see ourselves as extensions of our clients’ research and development, marketing and in-house legal teams. We proactively serve as the manager of the clients’ IP assets to ensure that their legal fees are a justifiable investment for the enhancement of their IP assets, which in turn increase the clients’ competitive edge in the market and the value of their company.
