Chinese access control leader Hongmen Advanced Technology Corporation is now involved in a new patent dispute with its industry rival Shenzhen Jieshun Science and Technology Industry Co., Ltd., according to recently disclosed information from the China National Intellectual Property Administration (CNIPA).
The CNIPA’s oral hearing schedule indicates that Jieshun has filed an invalidation request against one of Hongmen’s key patents, titled “Electric Fence Gate Capable of Three-Dimensional Rotation” (Patent No. ZL200810142110.6). The hearing is set for October 17, 2025, at CNIPA. While it remains unclear whether any litigation has been filed between the two companies, the invalidation proceeding signals the start of a formal dispute.
This is the same patent at the center of Hongmen’s ongoing lawsuit against Hikvision, in which it is seeking 10 million yuan in damages. On January 7, 2025, Hongmen filed a complaint with the Wuhan Intermediate People’s Court, alleging that Hikvision and it subsidiary had infringed the patent. The company demanded 10 million yuan in compensation for economic losses and 310,265 yuan in legal and related expenses, for a total claim of 10.31 million yuan.
The lawsuit subsequently led to a jurisdictional dispute. On June 5, 2025, the Supreme People’s Court (SPC) rejected Hikvision’s appeal to transfer the case to its home court in Hangzhou, affirming that even the sale of a single infringing product can establish jurisdiction. The ruling also clarified the legal boundaries of “forum shopping” in patent disputes—where plaintiffs strategically purchase products in certain jurisdictions to file suits there.
Hongmen’s patent in question has become a critical IP asset for the company. CNIPA records show it has faced eight invalidation challenges to date, with three of them resulting in official decisions to uphold the patent’s validity. One of the challengers was Guangdong Ankuai Intelligent Technology Co., Ltd., suggesting that Hongmen may have enforced this patent against Ankuai in the past as well.
This aggressive enforcement approach aligns with Hongmen’s long-standing stance on IP protection. The company has publicly emphasized its commitment to defending its patents and trademarks and has a history of initiating IP litigation, including cases that reached China’s Supreme People’s Court.
In 2017, for instance, Hongmen sued the Hongmenkai Electromechanical Equipment Business Department for using its trademark in brochures and business documents. It requested the court to order the defendant to cease infringement, change its business name, and pay damages.
The company later filed another suit with the Beijing Intellectual Property Court, arguing that the use of “Hongmen” in the name “Hongmen Jingcheng” constituted unfair competition—a claim the court upheld.
In 2022, the Supreme People’s Court ruled in favor of Hongmen in another case, ordering Shenzhen Caimen Intelligent Technology Co., Ltd. to cease infringing Hongmen’s patent for a “Sliding Door Frame-Type Cabinet” (Patent No. ZL200910105952.4).
According to the company’s official website, Hongmen was founded in 1993 and specializes in R&D, manufacturing, and services across a range of intelligent mechatronic products, including access control systems, retractable gates, barrier gates, fences, and industrial doors.
Founded in 1992, Jieshun Technology is a leading global supplier of smart parking and access control solutions, offering integrated systems such as parking management, barrier gates, pedestrian gates, and centralized cloud-based monitoring platforms. A 2023 ranking by the Yubo Industry Research Institute listed Jieshun, Hikvision, and Hongmen among the top ten channel gate brands in China.
