The patentee who wants to enforce his patent in China should pay attention to the principle of allocating the burden of proof which is one of the most important factors affecting whether the intended goal could be achieved in patent infringement litigation.

Forum shopping is an important issue in a patent infringement lawsuit. Under the Chinese Civil Procedure Law, a plaintiff in an infringement case shall file the litigation with a court at the place of infringement or at the place where the defendant is domiciled. However, it often happens that the alleged infringing manufacturer or seller is not in the jurisdiction where the plaintiff wishes to bring the litigation.

A common question regarding English commercial signs, such as trademarks, personal names, or trade names, is how to protect their Chinese equivalent. On the one hand, the holder of the English commercial sign failed to select the Chinese equivalent for some reasons, or failed to have it registered as a trademark in a timely matter. On the other hand, the holder may have used the Chinese equivalent together with the English mark in commerce, or have used the Chinese equivalent passively.

When foreign brands enter into the China market they are generally translated into Chinese, either for use by the brand owners, or by Chinese media and Chinese public. According to authorities including the China Supreme Court, some Chinese equivalents for its English trademarks are protected, such as GOOGLE, CANON, LAND ROVER, HARLEY (of Harley-Davidson), MICHELIN, PORTS INTERNATIONAL, GIOGRIO ARMANI, SOTHEBY’S, RITZ CARLTON, and FREDDIE MAC. Others are not protected, such as VIAGRA, SONY ERICSSON, DELL, MICHAEL JORDAN, and RANDOM HOUSE. And still others are protected in one case while not protected in another, such as LAFITE.

In June 2015, the Beijing High Court (second instance court) sustained the decisions of the Beijing First Intermediate Court (first instance court) and the Trademark Review and Adjudication Board (TRAB), and held that the opposed mark “FANG DI MEI in Chinese” (FREDDIE MAC in Chinese) constitutes similar to the cited mark “FREDDIE MAC” owned by Federal Home Loan Mortgage Corporation (“Freddie Mac”) in terms of similar services in Class 36. The key issue of this case is the determination of similarity between Chinese equivalent and English mark.

This is the first case for successful enforcement of biological patent in China, which clarifies a feasible definition of new protein patent, i.e. defining homology, origin (species), and function simultaneously. Furthermore, this case provides directions to judgment of future invalidation and infringement cases of new protein patents.

The patentee of this design, Zhiming LI, holds a design patent No. ZL03319125.5, titled “Toothbrush Handle”, which was granted and announced on September 17, 2003. On the same day of the announcement, the patentee authorized Guangdong Sugere Daily Chemicals Co., Ltd. (“Sugere Company” hereinafter, the legal representative of this company is Zhiming LI himself) to make and sell the patented product exclusively.

In patent invalidation or infringement procedures, to prove an uncertain publication date of a prior art or prior design, a plurality of evidences is generally required to form a complete and reliable chain of evidence. Evidence collection and organization usually rely on patent attorneys’ understanding of law and practical experiences. Within a novelty grace period, certain pre-filing disclosures will not cause lose of the novelty of the subsequent patent application. There are rigorous restrictions on such grace period disclosures. It is of vital importance to determine whether a disclosure of an invention-creation before filing can be regarded as a grace period disclosure.

Prior design defense is a very important non-infringement defense system in design patent infringement lawsuits, which allows the People’s Court to determine whether an infringement is established simply by determine whether the accused design constitutes similar to the prior design without evaluation of validity of the design patent.[1] This case shows that although a design patent application was submitted before the filing date of the involved patent and published thereafter the filling date (hereinafter referred to as the “earlier design”) does not constitute as prior design. It can be used, however, as the basis for a non-infringement defense by referring to the prior design defense rules, thereby substantially expanding the applicable scope of prior design defense.
