Research on Antitrust Regulation of Standard Essential Patent Abuse: A Case Study of Huawei v. IDC

As an important component of technical standards, the abuse of standard essential patents (SEPs) may significantly distort market competition and infringe upon the interests of a wide range of consumers. This article addresses the typical case of SEP abuse, namely the abuse of SEPs in the Huawei vs. IDC case—such as implementing unfair high-priced licensing and discriminatory licensing conditions—and raises specific issues regarding antitrust law's regulation of SEP licensing: The "Guidelines on Antitrust Regulation of Standard Essential Patents" face various complex and special challenges in practice. First, SEP abuse renders the FRAND principle (Fair, Reasonable, and Non-Discriminatory) a mere formality. Second, SEP abuse generates anti-competitive effects such as patent hijacking and patent forests. Third, when regulating SEP abuse under China's "Antimonopoly Law," it is essential to consider standard-related factors, provide detailed guidance on specific cases in the "Guidelines on Antitrust Regulation of Standard Essential Patents," standardize the formulation of patent licensing rate standards, and strengthen market supervision. The Huawei vs. IDC case is a concrete instance handled by China in the practical field of antitrust regulation of standard essential patents. The adjudication approach is conducive to guiding the establishment and improvement of China's antitrust regulatory system for standard essential patents, achieving a balance between encouraging innovation and safeguarding competition, and promoting the development of the technical standards industry.
