YUHONG IP LAW Firm was founded by Mr. Dajian WU and a group of experienced IP attorneys and lawyers. Mr. WU, the  only person who was entitled China National Outstanding Patent Attorney by the Central Government, i.e., the State Council of China, used to be the President of China Patent Agent (H.K.) Ltd. which is the largest patent and trademark law firm in China.

YUHONG provides overall IP services in patents, trademarks, copyrights, and other IP related areas to clients around the world. YUHONG has a professional team with not only profound expertise and foreign language ability but also great commitment to work. Having worked devotedly in well-known IP law firms in Greater China Region for many years, partners of YUHONG have gained rich experience in dealing with all sorts of IP cases, especially foreign patent cases, and in managing an IP law firm. With the development of business, YUHONG has established five branches in China and plans to set up its branches abroad in the near future.

Our Advantages

YUHONG attaches great importance to quick response. It is required that all inquiries and emails from clients and all communications from patent and trademark offices be processed or transferred immediately.

  1. 2. Reasonable & Competitive Charges

On the premise of keeping a much higher level of overall service quality, our charges can still be much more competitive than those of other major firms in China. Our charges are quite flexible and negotiable depending on situations of individual cases and specific requirements of clients.

  1. 3. Excellent Patent & Trademark Team

Most of the patent and trademark attorneys in YUHONG are senior attorneys with many years of experience in handling foreign cases including patent counseling, drafting, examination, re-examination, invalidation, and litigation, as well as trademark application, search and analysis, opposition, licensing, assignment,  litigation, etc.

YUHONG pays great attention to the quality of translation. All documents related to patent application and other IP matters are translated by our professional in-house translators. They are proficient in technical background and foreign languages as well as patent translation techniques, and are highly aware of the meaning of patent protection, the structure and features of IP related texts in particular patent documents, the gist and techniques of patent examination process, and the history and current situation of patent systems. Their translations of patent documents are therefore more up to the standard of legal text.
