Recently, the State Intellectual Property Office issued the 'Notice of the State Intellectual Property Office on the Selection of the 25th China Patent Award'. The invention patent 'Photocurable hydrophilic polymers, coating compositions based thereon and hydrophilic lubricating coatings and products' filed by Jiangsu Baisaifei Biotechnology Co., Ltd. won the China Patent Excellence Award.
Hydrophilic lubricating coating is a material widely used on the surface of interventional medical devices. Its core function is to facilitate doctors to smoothly push the device to the diseased site and at the same time reduce the friction damage of the device to human tissue. It is the core raw material of interventional devices. The award-winning patent realizes all-round protection of the hydrophilic lubricating coating from molecular structure to coating composition, cured coating and coated medical devices through the design of photo-curable hydrophilic polymers. It is the first in China to meet the strict requirements of coatings from macro-firmness to micro-firmness, and its performance reaches the international leading level. SurfLubri® medical hydrophilic super-lubricant coating, one of the core coating products formed based on this core patented technology, has been used by hundreds of domestic and foreign medical device manufacturers in neurological intervention, cardiovascular intervention, digestive intervention, urinary intervention, respiratory anesthesia, surgical drainage, endoscopy, ophthalmology and other fields, and has obtained NMPA, FDA and CE registration certification. In addition, the patent portfolio developed around this core technology has broken through the restrictions on imported coating patents, fully ensuring the domestic sales and export of coated device products for downstream customers.
Baisaifei has always adhered to independent innovation as the driving force of the enterprise, established an intellectual property management system that is in line with international recognition, and actively carried out global patent layout in the fields of coating raw materials, coating coating equipment, coated medical devices, and coating inspection and testing instruments. As of the end of May 2025, the group has applied for more than 200 patents, making it the enterprise with the most medical coating-related patents in China.
This award is a full affirmation of Besaifei's R&D innovation capabilities and intellectual property management level. In the future, the company will continue to adhere to the innovation-driven development concept, continuously improve its R&D transformation capabilities and product market competitiveness, and make greater contributions to promoting the development of medical functional coatings and the growth of the high-end medical device industry.
The China Patent Award is the highest honor in the field of patents in China. It is co-sponsored by the State Intellectual Property Office of China and the World Intellectual Property Organization. It aims to conscientiously implement General Secretary Xi Jinping’s important exposition on intellectual property work and the decisions and arrangements of the Party Central Committee and the State Council, deeply implement the intellectual property strategy, stimulate the innovation vitality of the whole society, accelerate the construction of an intellectual property power, encourage and commend patentees and inventors (designers) who have made outstanding contributions in implementing innovation and promoting economic and social development.
