Intellectual Property Management Plan

In alignment with the mission of a green environmental engineering company and our focus on addressing the complex relationship between humans and nature, we are actively enhancing our technical capabilities in areas such as process carbon reduction, alternative auxiliary materials, renewable energy, and the co-processing of waste in cement kilns. We are gradually integrating resources across various departments and affiliated enterprises, strengthening intellectual property awareness among our personnel, and implementing the principles of a circular economy through the application, maintenance, and value-added utilization of relevant rights. This approach helps reinforce our leadership in the industry while safeguarding our valuable technological achievements.

Protection Management Measures

Trademark Management

While promoting new businesses, trademark issues are carefully considered. For the design, registration, and authorized use of trademarks, co-signing and consultation with professional units are required to protect the Group's brand rights and interests.

Patent Management

The responsible unit evaluates the development and adoption of new materials and technologies, and periodically collaborates with external consultants to analyze search results and discuss application strategies, while monitoring and engaging with relevant international technology trends.

Copyright Management

During employment, employees are required to comply with copyright laws, avoid using works that infringe on others' rights, and are periodically informed to establish correct copyright awareness.
All R&D and creative outcomes funded by TCC and completed by business
partners include stipulated clauses on rights ownership and non-infringement
guarantees in standard contracts and procurement orders.

Trade Secret Management

Commercial partners are required to sign non-disclosure
agreements (NDAs) or agree to confidentiality
clauses.
All employees must sign an Employee Confidentiality
and IP Ownership Agreement upon onboarding.
Key IP employees must also sign a separate Employee
Covenant Agreement (including non-compete
and non-solicitation clauses) upon resignation

In recent years, TCC has been actively expanding internationally and accelerating its penetration into the Asian market.
To carefully plan layout strategies and overseas business development, important implementation items such as overseas intellectual property layout analysis, the establishment of intellectual property law compliance systems, and the integration of intellectual property management systems are regularly monitored through the Company's business reports to track progress and appropriately respond to potential operational risks.

Implementation Status

TCC reports intellectual property-related matters to the Board of Directors at least once a year, with the most recent report submitted on December 4, 2025. TCC's main implementation in recent years is as follows:

2023	Create branding for energy storage and renewable energy power sales businesses and deploy trademarks in various regions. Continue to promote online supplier surveys and documentation, allowing suppliers to submit confidentiality declarations online when bidding for sensitive projects, strengthening trade secret protection; in addition to confidentiality regulations, non-compete measures have also been established for employees with access to core technologies to enhance protection mechanisms. Patent planning for energy storage business Technical Aspect With ultra-high performance concrete (UHPC) combined with fire-resistant material layers as the core of the cabinet, expanding outward to various aspects including thermal runaway prevention methods, assembly structures, battery module design, and power management. Deployment Aspect Focusing on Taiwan applications as the foundation, patent filings are extended to major markets (including the United States, Europe, China, Japan, and South Korea) through priority claims and the Patent Cooperation Treaty (PCT) framework, with Taiwan patents being granted successively. The low-carbon formula for ultra-high performance concrete is protected as a trade secret, and its application in building materials (KT board and building structures including KT board) has already been filed for patent application in Taiwan. At the intellectual property management level, in addition to implementing the ISO9001 management system for energy storage business, we have begun inventorying trade secrets, patentable technologies, and relevant management manuals for R&D-driven areas such as energy storage, batteries, and low-carbon materials. We have also engaged suitable external law firms. Looking ahead, we aim to establish a TIPS (Taiwan Intellectual Property Management System) to strengthen the protection of patents and trade secrets, thereby enhancing industrial competitiveness.
2024	Obtained TIPS (Taiwan Intellectual Property Management System) Certification. Patent Deployment: Energy Storage Business Focus areas for patent applications include four technical aspects: Ultra-High Performance Concrete (UHPC) energy storage cabinet design, safety, Energy Management Systems (EMS), and battery module design. Cement Business Patent applications have been filed for technologies such as UHPC KT slabs and waste glass powder. Battery Business Patent applications for cylindrical lithium baery electrode body and cell winding technologies have been filed across multiple countries.
2025	Passed the re-certification of the Taiwan Intellectual Property Management System (TIPS) (Announcement available at: https://www.tips.org.tw/body?sno=BGCD ; Certification valid until: December 31, 2027) 1. Applied for and passed the TIPS Level A (2016 Version) re-certification for patents and trademarks under the name "Taiwan Cement Corporation." 2. Continuously deepen trade secret and copyright management mechanisms. Continued expansion of patent portfolio: Energy Storage Business (1) Successfully obtained 18 invention patents in Taiwan and Japan, covering four technical aspects of Ultra-High Performance Concrete (UHPC) energy storage cabinets: cabinet design, safety, Energy Management System (EMS), and battery module design. (2) In addition to ongoing patent applications in the US, Europe, Mainland China, Korea, and Hong Kong, patent coverage for UHPC energy storage cabinets has recently been expanded to the African region (including Ghana, Cameroon, Ivory Coast, Nigeria, Cape Verde, Algeria, and Morocco) to align with the Group's global deployment. Cement Business (1) Regarding the promotion of UHPC applications, utility model patents have been obtained for UHPC precast wall panels, UHPC RCPs (Reinforced Concrete Pipes), 3D-printed UHPC objects, and energy storage cabinet structures. (2) In terms of material R&D for cement and concrete, regarding the technology of using waste photovoltaic (PV) panel glass sand as a pozzolanic material in cement, the patent layout has been expanded beyond Taiwan to the US, Europe, and Mainland China. Furthermore, patent applications have been filed for the technology of applying Recycled Concrete Aggregate (RCA) from construction waste to permeable bricks/pavements, while the feasibility of patenting other technologies is currently under evaluation. Battery Business In addition to the ongoing multinational patent examinations for two existing technologies related to the electrode body and cell winding of cylindrical lithium batteries, patent applications have been filed for two additional technologies: battery internal resistance measurement and multi-pattern fabrication methods for battery coatings.
