Batch Preliminary Examination of Patent Applications: A Typical Case of Supporting Enterprises (Part IV)
In 2024, the Jiangsu Intellectual Property Protection Center (hereinafter referred to as “Jiangsu Protection Center”) conducted high-standard batch pre-examination pilot work in accordance with the National Intellectual Property Administration's pilot program requirements. Focusing on two pre-examination industries—high-end equipment and new functional and structural materials—as well as the semiconductor sector, the center accelerated innovation protection for Jiangsu enterprises. Through a service model featuring pre-examination proactive engagement on technical solutions, dedicated one-on-one examiners, and full-process tracking, the Center received 128 batches of pre-examination requests from 100 enterprises across the province throughout the year. Among these, 9 were national-level “Little Giant” enterprises specializing in niche markets, and 40 were provincial-level or higher specialized enterprises. The Center submitted 359 pre-examined applications to the CNIPA, with 144 already granted. Jiangsu Protection Center's batch pre-examination review of invention patent applications alleviated urgent needs among key innovation entities.
Case Study 4: Jiangsu Jinshi Machinery Group Co., Ltd. Overcomes Ultra-High Pressure Fracturing Technology Barriers Through Batch Pre-examined Patent Technologies
Jiangsu Jinshi Machinery Group Co., Ltd., a national-level specialized, refined, distinctive, and innovative “Little Giant” enterprise, specializes in the R&D, production, sales, and service of high-pressure oil and gas wellhead equipment in China. Its primary products include casing heads, high-pressure oil and gas wellhead assemblies, choke and kill manifolds, control systems for drilling control equipment, fracturing processes, and other petroleum drilling and production equipment. Its products serve major oilfields across China and are exported to over 30 countries and regions. Its wellhead equipment and Christmas trees have been consecutively named China's Petrochemical Equipment Famous Brand Products, Jiangsu Provincial Famous Brand Products, and Jiangsu Provincial Key Cultivated Export Famous Brand Products.
In 2024, the company submitted one batch of 7 invention patent applications for pre-examination to the Jiangsu Protection Center. Six have been authorized, bringing the cumulative total of invention patents authorized through the center's pre-examination channel to 12, with an average authorization cycle of 2 months. The batch pre-examination of invention patent applications focused on areas such as high-temperature thermal recovery wellheads and intelligent choke and kill manifolds, with some patented technologies already industrialized. Among these, the batch-reviewed patent technology equipment “A Type of Ultra-High Pressure Large-Bore Fracturing Single-Well Manifold” employs novel materials and structures to ensure stable operation under extreme fracturing conditions, significantly enhancing safety. Its ultra-high pressure large-bore design improves operational efficiency. This patented technology further solidifies the company's leadership in oil and gas equipment manufacturing, providing robust technical support for petroleum enterprises developing challenging oil and gas fields, and is expected to have a profound impact on industry development. In 2024, the company sold 850 sets of high-temperature thermal recovery wellhead products, with 35 sets of orders pending shipment. The sales revenue of these products reached approximately 270 million yuan, accounting for 51.9% of the company's total sales. The sales revenue of intelligent choke and kill manifolds exceeded 35 million yuan, accounting for 6.7% of the company's total sales.
The company's newly patented products—high-temperature thermal recovery wellheads and intelligent choke and kill manifolds—align with the industry's future direction of “promoting deep-earth resource exploration and extraction” and fit within Jiangsu Province's “1650” industrial system key supply chains. Through its batch pre-review service channel, the center actively supports high-end equipment manufacturing enterprises across the province, effectively enhancing the quality and efficiency of core technologies within the innovation chain for new productive forces.
Patented high-temperature thermal recovery wellhead products are as follows:
Patented intelligent choke and kill manifold products are as follows:
