Jiang Ying's career as a judge

Presided over nearly 200 cases of intellectual property disputes, most of which were foreign-related, difficult or new types, which had great influence in all walks of life. The case of the conflict between the design of Shangri-La and Coconut Wind and the trademark right she tried was the first case in China to request the invalidation of the design patent on the grounds of conflict with prior rights according to the revised Patent Law. Because there is no precedent to follow, it brings difficulties to the trial of the case. After reading a large number of relevant papers, she got a detailed understanding of the legislative background, correctly understood the legislative intent, put forward the basic principles of protecting prior rights, and confirmed that the application for a design that conflicts with other people's prior well-known trademarks belongs to immediate infringement, which constitutes trademark infringement, and was supported and affirmed by the collegial panel. The judgments of these two cases have been valued and praised by experts. In the China Patents and Trademarks magazine published in Hongkong, some people commented: "The Shangri-La judgment provides a classic precedent for solving the problem of rights conflict in the field of intellectual property rights, and opens up a new way of thinking for the problem that has puzzled the industry for a long time."

The cases of copyright infringement and unfair competition between Sohu and Sina, two major Internet portals in China, involve the ownership and infringement determination of 72 mobile phone pictures and 7 articles, as well as the damage determination of competitors' business reputation, which has aroused widespread concern in society, involving complex legal relations and abundant evidence. The trial alone lasted for three days, and the workload was very heavy. As the undertaker, Comrade Jiang Ying carefully read more than 20 volumes of case files, carefully studied the case, and put forward reasonable and well-founded solutions, which enabled the case to be successfully detected and widely reported by major media in Beijing. In the first dispute case of confirming the non-infringement of "Peter Rabbit" trademark right, she visited the relevant departments of the Industrial and Commercial Bureau and the Trademark Office for many times, consulted relevant experts and consulted a lot of information. After studying with the collegial panel for many times, in the absence of legal provisions, she first clarified the preconditions for filing a non-infringement lawsuit in the form of precedent. In the case of Qin Shaoyin v. Beijing Rongbao Auction Co., Ltd., she creatively put forward the principle that using works for auction without the author's permission does not constitute copyright infringement.
