Standard-essential patent legal protection in China’s telecommunication industry: an international trade and economy perspective

Standard-essential patents (SEPs) are specific types of patents that protect the technology incorporated in a standard. China has one of the world's largest telecommunication markets, and its legal policies and practices regarding SEP protection profoundly influence the competitive environment of the Chinese telecommunication market, international economic and trade cooperation, and global telecommunication technology innovation. Recently, frequent disputes in the communication sector surrounding SEPs in China's judicial practice revolved around the fair, reasonable, and non-discriminatory (FRAND) principles, embodying three key issues: patent hold-up, licence fee rates, and anti-suit injunction. Regarding the patent hold-up and hold-out of SEPs in the telecommunication industry, a balance of interests between SEP holders and implementers in licence negotiations should be achieved under the guidance of the principles of FRAND from the perspective of legislation, administrative management, and the judiciary. Concerning licence fee rates, billing benchmarks should be judged based on individual cases, utilizing a comprehensive approach combining comparable licence agreement methods and top-down methods to determine a fair and reasonable licencing fee acceptable to all parties. In the conflict between anti-suit and anti–anti-suit injunctions, improving the anti-suit injunction rules and international cooperation mechanisms is necessary to achieve fair and non-discriminatory judicial processes and judgment results.
