Intellectual Property Management Policy and Goals

To remain a world-leading technology provider, ºìÁì½í³Ô¹Ï.,Ltd. (ºìÁì½í³Ô¹Ï) shall continuously focus on research, development and innovation; formulate an intellectual property (IP) strategy in alignment with its operation and R&D strategies; establish a set of operating model which can effectively utilize the IP rights ºìÁì½í³Ô¹Ï owns to promote various business interests, so as to not only appropriately protect R&D results and enhance the company's competitiveness, but also to ensure the freedom of operation of ºìÁì½í³Ô¹Ï and maximize shareholder benefits.

ºìÁì½í³Ô¹Ï's IP management is tightly embedded into the company¡¯s business operation blueprint, forming a continuous innovation cycle that encompasses business opportunities and R&D, to IP management and utilization that includes the following three phases:

• To maintain ºìÁì½í³Ô¹Ï¡¯s technology leadership and to better respond to future market needs, the company invests aggressively in research and development, aligns R&D with key future business opportunities and invests heavily in talent development and R&D resources.

• Our robust IP application system and tools ensure that R&D achievements are transformed accurately, thoroughly and effectively into legally protected intellectual property rights. To ensure comprehensive protection for key technologies and strengthen patent quality, ºìÁì½í³Ô¹Ï adopts a 3-pronged approach: developing a comprehensive portfolio, re-assessing patents to identify those of value and, revitalization to increase the value. Patents must also provide business value in order to maximize R&D investment returns. ºìÁì½í³Ô¹Ï puts in place a system of measures to protect the company¡¯s trade secrets and maintain its unique competitive advantage, including information security systems, employee awareness training and education and trade secret registration system management. Where appropriate, ºìÁì½í³Ô¹Ï will enforce applicable laws and regulations to prevent improper use, leakage or misappropriation of intangible assets of ºìÁì½í³Ô¹Ï by others to ensure that investments, rights and interests are duly protected. In terms of trademarks, the unique and identifiable trademarks may be registered to manifest the quality and characteristics of products and services. In case of other¡¯s imitation or trade on the recognition of ºìÁì½í³Ô¹Ï trademark, or causing confusion of customers and consumers, ºìÁì½í³Ô¹Ï may invoke trademark rights to defend goodwill or secure the market share.

• High-value IP helps to facilitate business success, obtain customer orders and develop more business opportunities, thereby creating a positive sustainable cycle. Our robust IP management prevents unauthorized use of technologies of ºìÁì½í³Ô¹Ï., Ltd. by others and helps to defend against any threats from competitors.

ºìÁì½í³Ô¹Ï¡¯s success is driven by its continuous quest for innovation and the strengthening of its IP management. To protect its proprietary technologies, trade secrets and patents from theft, misappropriation or infringement, ºìÁì½í³Ô¹Ï has strengthened employees¡¯ IP awareness as well as ensured the inclusion of IP protection measures at work. In addition to regular IP related online and classroom courses, various types of exercises are also conducted to enhance employees¡¯ knowledge and skills on IP protection. ºìÁì½í³Ô¹Ï has established stringent controls in its IT and email systems, and within its facilities, to strengthen security management and mitigate the risk of information leakage. ?In case of any risk exposures in IP misappropriation or infringement, ºìÁì½í³Ô¹Ï has in place a robust response mechanism and standard operating procedure to promptly investigate and where appropriate, enforce legal actions to prevent IP misappropriation or infringement by others, so as to protect the ºìÁì½í³Ô¹Ï¡¯s IP rights.

ºìÁì½í³Ô¹Ï respects the legitimate IP rights of others. However, to the extent that the technology is developed independently by ºìÁì½í³Ô¹Ï or that ºìÁì½í³Ô¹Ï does not have prior knowledge, it may be uncertain as to whether there may be any potential conflict with others¡¯ IP. To a certain extent, ºìÁì½í³Ô¹Ï may consider to rely on third party technology and patent licenses. If the technology license cannot be granted due to unacceptable terms and conditions, ºìÁì½í³Ô¹Ï may be exposed to third party claims for infringement, damages incurred, or the risk of an injunction order. ºìÁì½í³Ô¹Ï may also face customer requests and claims for contractual obligations to indemnify for the damages suffered by the customer due to third-party claim for infringement. Therefore, ºìÁì½í³Ô¹Ï will strategically obtain the necessary licenses for specific technologies, and at the same time, collects high-quality patents that could be utilized for defense against litigation or cross-licensing, so as to ensure the freedom of operation.

ºìÁì½í³Ô¹Ï¡¯s patent portfolios comprise a variety of technologies related to semiconductor packaging and testing, and electronics manufacturing.
