SEMCORP’s End-to-End Intellectual Property Management System Sets a Benchmark for Innovation in New Energy Materials

Technological innovation is the cornerstone of a company’s long-term development, while a robust intellectual property management system provides the underlying support needed to safeguard innovation and drive continuous technological advancement.

As a global leader in lithium-ion battery separators, SEMCORP has spent years developing a systematic intellectual property management framework. Covering patent R&D and portfolio planning, risk assessment, standardized management and industry best-practice sharing, SEMCORP has established a comprehensive IP management system tailored to the R&D needs of new energy materials, ensuring that every technological innovation is effectively protected.

Strategic Patent Portfolio Focused on Quality and Effectiveness, Building a Strong Safeguard for R&D Innovation

As of July 9, 2026, SEMCORP held 910 proprietary R&D patents, including 574 granted patents in China and overseas and 94 PCT patent applications. The company has also completed the acquisition of Teijin’s foundational separator patents, establishing a multi-layered patent protection matrix.

SEMCORP’s patent portfolio is closely aligned with its core R&D priorities and comprehensively covers its proprietary technologies across the full range of CCS ceramic-coated separators, PCS polymer-coated separators and hybrid multilayer-coated separators. These technologies have been developed into comprehensive core patent families, precisely supporting the company’s day-to-day R&D and product iteration needs.

The strength of SEMCORP’s patent portfolio has been repeatedly validated through official proceedings. Several of the company’s core patents have faced challenges seeking invalidation. One patent remained fully valid after five separate invalidation requests, while another retained its complete patent rights despite the opposing party submitting more than ten pieces of comparative evidence. These cases provide strong evidence of the originality and robustness of SEMCORP’s proprietary technologies.

End-to-End Risk Management to Standardize the Management of R&D Outcomes

Throughout the entire R&D lifecycle, SEMCORP has established a regularized intellectual property risk management mechanism.

Internally, the system covers every stage from material formulation and process improvement to product trials. Patent searches and innovation-point identification are conducted in parallel to ensure that technological achievements are promptly secured through appropriate IP rights.

Externally, SEMCORP works with leading global intellectual property law firms to establish professional legal support teams. Standardized procedures have been developed for patent searches, assessment of patent rights stability and resolution of ownership disputes, enabling the company to identify and mitigate R&D and patent ownership risks at an early stage.

At the same time, SEMCORP has entered into patent licensing cooperation with leading companies in the industry, creating channels for technological exchange and promoting the healthy development of industry technologies while maintaining compliance.

Authoritative Certifications and Recognition Establish SEMCORP as a Benchmark for Industry IP Management

Years of standardized operations have enabled SEMCORP Shanghai to obtain multiple nationally and internationally recognized certifications and honors. The company has successfully obtained the ISO 56005 Innovation and Intellectual Property Management Level II certification and intellectual property compliance management system certification. It has also been recognized as a National Intellectual Property Advantage Enterprise, a Shanghai Patent Demonstration Enterprise and a Shanghai Specialized, Sophisticated, and Innovative SME.

In 2025, the company’s invention patent for a wide-temperature-range, low-shrinkage separator was selected as one of the “Top Ten Outstanding Invention Patent Cases” under the Belt and Road Initiative, becoming a representative example of innovation in China’s new materials sector.

Looking ahead, SEMCORP will continue to deepen the integration of intellectual property management and R&D, increase investment in the development of cutting-edge separator technologies, expand its high-quality patent portfolio and further refine its IP management standards.

With a comprehensive intellectual property management system, SEMCORP will continue to drive technological innovation and contribute to the high-quality development of the industry.
