As one of the youngest patent systems in the world, China’s patent system and policies are developing rapidly and already have an increasingly strong influence globally. On the eve of the 20th World Intellectual Property Day, the Chinese National Intellectual Property Administration (CNIPA), the Supreme People’s Court and some other authorities published their annual IP reports and white papers. The data published reflects that a significant increase has been achieved for China in terms of the numbers of patent applications, valid patents for invention and patent litigations. After 35 years of quiet development, the patent system is now familiar to people and widely recognised by market players in China.

In order to get a more intuitive sense of this progress, the 2019 data has been compared with the corresponding data for 2010.

Patent applications for inventions in China2010 – 391,000
2019 – 1.401 million
Patent Cooperation Treaty international applications accepted by the CNIPA2010 – 12,000
2019 – 61,000
Valid patents for invention2010 – 564,000
2019 –1.862 million
Patent infringement litigations accepted by the first-instance court2010 – 5,000
2019 – 22,000

In addition to the growth in various data, one of the most remarkable changes in patent litigation is the substantial increase in the amount of compensation awarded for infringement of patent rights. In 2019, of the 962 civil second-instance cases accepted by the Intellectual Property Tribunal of the Supreme People’s Court, there were 17 cases in which the rights holders claimed compensation for infringement exceeding Rmb10 million, and three cases exceeded Rmb100 million. According to the investigation report released by the Intellectual Property Research Centre of Zhongnan University of Economics and Law in 2013, the situation at that time was that 97.25% of the judgments adopted statutory compensation when accessing the amount of compensation for infringement of patent rights. The average amount of statutory compensation in patent infringement cases since 2008 has been only Rmb80,000, which accounts for only one-third or even less of the plaintiffs’ claims. Today, the abovementioned problems have been solved to some extent: according to the report issued in November 2019 by Chen Jinchuan, vice president of Beijing Intellectual Property Court, in the foreign-related civil cases heard by the Beijing Intellectual Property Court, the average amount of compensation claimed by the plaintiffs is about Rmb2.77 million, and the average amount of compensation supported by the court is about Rmb1.36 million – meaning that the support rate of claimed compensation is 49.1%.

With the approach of the fourth amendment to the Patent Law, the upper limit of the statutory compensation will probably be increased from the previous Rmb1 million to Rmb5 million, and unprecedented punitive compensation of up to five times the amount is set to be introduced. Meanwhile, this amendment to the Patent Law will further reduce the difficulty of rights holders in furnishing proof for compensation. These measures will encourage rights holders to enforce their rights through civil litigation. Nevertheless, at the same time, they may also attract more NPEs coming to China, making traditional preventive measures, such as freedom-to-operate analyses, more important.

A trend of strengthening judicial protection of patent rights has been apparent from judicial trials in recent years. For instance, among the 586 civil second-instance cases of patent infringement disputes heard by the Supreme People’s Court in 2019, the winning rate of the rights holders stands at 61.2%.

This trend is also reflected in some innovative guiding cases. For example, in the recent patent infringement dispute between Dunjun Company and Tengda Company, the Supreme People’s Court expanded the interpretation of the ‘use’ of patent method as set forth in Article 11 of the Patent Law by a newly established “irreplaceable substantive role” rule, at least for inventions in the field of network communication in which multiple parties are usually involved. By such a rule, if the accused infringer, for the purpose of production and business, solidified the substance of the patent method into its infringing product, and, when the end user uses the infringing product in a routine manner, all steps of the patent method are naturally reproduced, then the act of the accused infringer or the results of such act played an irreplaceable substantive role to infringe the patent method. Although the judgment emphasises the particularity of the field of network communication, it is believed that the rule may also offer guidance for method patents in other fields.

Introduction to the judicial system of patent protection in China

In China, patent rights can generally be enforced through an administrative or judicial route, while a patent infringing act does not itself bear criminal liability. Regarding the administrative route, the patentee may apply to the local administrative authorities for IP rights protection. This procedure is processed relatively quickly, and the rights holder can obtain the injunction but cannot receive compensation. In addition, the administrative decisions of the infringement disputes are not final, because the parties can institute legal proceedings against these decisions. Therefore, in order to seek more comprehensive protection, the rights holder may need to enforce its rights through the judicial route.

In China, patent infringement litigation adopts a two-instance trial system, as is the case in other civil litigations. Although the basic people’s courts designated by the Supreme People’s Court can hear cases regarding patents involved in disputes according to the judicial interpretation, almost all the cases of patent-involved disputes are under the jurisdiction of courts of the intermediate level or higher. At present, a ‘1 + 76’ patent judicial trial system has been formed in China – that is, 76 intermediate or higher people’s courts have jurisdiction over patent-involved cases in the first instance, while one IP Tribunal of the Supreme People’s Court is responsible for hearing all patent cases, either civil or administrative litigations, in the second instance.

The IP Tribunal was established at the end of 2018 and began to accept cases on 1 January 2019. In addition to cases relating to patents, the IP Tribunal also hears other cases with highly professional and technical features in the second instance, such as new plant varieties, layout designs of integrated circuits, technical secrets, computer software and technology monopolies. In the first year of operation, the IP Tribunal accepted 1,945 technical IP cases and concluded 1,433 of them – the case closing rate was as high as 73.7%, while the trial duration was reduced to an average of 73 days. The IP Tribunal has further strengthened the uniform application of law and made a large number of influential and exemplary cases through the centralised jurisdiction of the second instance of technical IP cases, which plays a positive role in improving the trial quality of patent-involved cases in China.

Among the abovementioned 76 intermediate or higher people’s courts with first-instance jurisdiction over patent cases, three IP courts in Beijing, Shanghai and Guangzhou, as well as 20 IP tribunals in other major cities, deserve special attention. These courts and tribunals are specialised in dealing with all kinds of IP case, which have accumulated rich experience in the first instance of patent cases after years of trial work, making them the first choice of the parties when choosing the court venue.

The technical investigation officer system of IP trials was formally established in 2014 in China by the ‘Interim Provisions of the Supreme People’s Court on Several Issues Concerning the Participation of Technical Investigation Officers of Intellectual Property Courts in Litigation Activities’. Shortly after its establishment, the abovementioned three IP courts began to try to invite technical investigation officers into cases involving advanced and difficult technologies. In the Beijing Intellectual Property Court, 89 technical investigation officers participated in 1,376 cases between 2015 and 2018. Similarly, the Guangzhou and Shanghai IP Courts have also accumulated rich experiences in adopting technical investigation officer system. In 2019, the ‘Provisions of the Supreme People’s Court on the Participation of Technical Investigation Officers in Litigation Activities in Intellectual Property Cases’ was promulgated, further promoting this system in other courts.

In addition, both parties in a case may also employ expert assistants to participate in the litigation. Therefore, at present, some courts have established a system in which specialised people’s assessors, technical investigation officers, expert assistants and judicial appraisal agencies participate together in the ascertainment of technical facts, which significantly solves the problem that the judge may lack the technical knowledge relating to the patent involved, thereby making the parties more confident to present their opinions on the technical issues in the court.

Recent progress and attempts

Unlike the common law system, there is no binding precedent in the Chinese judicial system. However, in order to reach uniform standards for the application of law, Provisions of the Supreme People’s Court on the Guidance of Cases and Regulations on the Implementation of the Provisions of the Supreme People’s Court on the Guidance of Cases were promulgated in 2010 and 2015, respectively, resulting in guiding cases playing increasingly important roles in Chinese judicial practice. The guiding cases are cited as reference in a large number of cases heard by lower courts, although they cannot be cited as grounds for judgment.

Besides the guiding cases, the judgments of the Supreme People’s Court often attract a high degree of attention due to the centralised trial of the second instance of technical IP cases. Recently, some typical cases were issued by the Supreme People’s Court, providing positive guidance regarding assessing the amount of compensation for patent infringement and the standards of determining joint infringement and contributory infringement.

In addition, the Supreme People’s Court has recently tried to coordinate the administrative and civil cases involving the same patent by using its function of centralised hearing in patent-involved administrative and civil cases at second instance. To some extent, this represents a future trend. In China, validity of a patent right can be challenged only through the patent invalidation procedure of the CNIPA, while the court has no function for examining the validity of patent rights in civil cases. The decisions of the CNIPA can be challenged at the Beijing Intellectual Property Court to institute an administrative litigation, which is separate from the civil infringement litigation. This brings about the problem that the civil procedure is usually influenced and restricted by the administrative procedure. And the overlapping procedures result in problems such as prolonged rights protection periods and unstable results. Moreover, the patentee may give different interpretations of claims in the separated procedures, that is, striving to uphold the patent right by limiting the extent of protection in the invalidation procedure, while obtaining the advantages in the infringement determination by expanding the extent of protection in the civil infringement litigation, therefore taking “advantage of both sides”. The abovementioned collaborative trial can effectively solve and avoid these problems.


China is currently undergoing fast-paced reform of its patent judicial protection system. In the foreseeable future, development may quicken, to provide an increasingly sophisticated, efficient, professional and rights-holder-friendly system to encourage an innovation-driven economy. Investors and companies must understand how China’s patent systems work and how they may change and develop.
