Ted Cheng, Partner, has more than 20 years of experience in intellectual property practice. His areas of expertise include mechanical engineering, thermofluids, fluid mechanics, optoelectronics, and computer peripheral products. He holds both bachelor’s and master’s degrees in Mechanical Engineering from National Taiwan University, as well as an LL.M. in Intellectual Property Law from the University of New Hampshire Franklin Pierce School of Law. This background equips him with a strong foundation in engineering and international intellectual property law.
Ted has passed the US Patent Bar Examination and is qualified as a Taiwan Patent Attorney and a China Patent Agent. He began his career at Chien Chyun Intellectual Property Office, where he built a solid foundation in patent practice. He subsequently joined Inventec’s Intellectual Property Department, where he was responsible for patent mining, patent valuation, and infringement analysis, gaining valuable in-house experience in intellectual property management and technology portfolio development. This combination of private-practice and in-house experience gives Ted a thorough understanding of patent prosecution, technology valuation, and the practical needs of businesses.
As a Partner at Taiwan Advance Patent & Trademark Office, Ted advises domestic and international technology companies on cross-border patent filings, patent portfolio development and management, and related contentious matters. Drawing on technical, legal, and commercial perspectives, he helps clients develop intellectual property protection strategies with tangible business value. His practice covers key jurisdictions including Taiwan, the United States, Europe, Japan, South Korea, and China, and he has long served clients in display technologies, electronics, computer hardware, optoelectronics, and mechanical engineering.
Leveraging his cross-disciplinary education and extensive practical experience, Ted places particular emphasis on transforming clients’ technologies into patent assets that support their commercial objectives. Beyond securing patent rights, he focuses on the quality, usability, and long-term strategic value of patent portfolios. His pragmatic approach, technical depth, and commercial awareness make him a trusted adviser on cross-border patent strategy and technology-driven intellectual property matters.
Roger holds both a bachelor’s and a master’s degree in Mechanical Engineering from National Taiwan University. He began his career as an R&D engineer in the technology sector, where he gained three years of experience in research, development, and project execution. Rather than working on a single component within a large-scale project, he sought a role in which he could manage the overall workflow, exercise professional judgment, and take responsibility for the outcome of each matter. He found this in patent practice, which combines technical understanding, logical analysis, and drafting skills. From technical interviews and filing strategies to specification drafting and subsequent responses, patent work enables practitioners to participate deeply in and coordinate every stage of a case. This led him to pursue a long-term career in the patent field.
In handling patent matters, Roger is skilled at breaking down complex technologies, developing a clear understanding of their essential features, and translating them into patent documents with meaningful protection value. He believes that the purpose of patent services is not merely to obtain a patent grant, but to understand the client’s commercial objectives, technological value, and potential risks arising from its R&D investment, and then to formulate a rights strategy that offers practical protection. Where a client’s expectations differ from the practical risks involved, he explains the relevant advantages and disadvantages and seeks to preserve room for future arguments and adjustments through the specification and filing strategy.
Early in his career, Roger handled a patent dispute from invalidation proceedings through administrative appeal and administrative litigation. Although the outcome was not ideal, the matter impressed upon him that the focus of litigation and responses should not be simply to attack the opposing party, but to present clear, credible, and persuasive arguments that enable the decision-maker to understand and accept the client’s position. Since then, he has placed particular emphasis on identifying the key issues in responses, invalidation proceedings, and contentious matters, while addressing the concerns of the patent authority, the court, and the client.
In addition to individual casework, Roger has also provided long-term support to a client that initially had limited experience with patent systems and practice. Beginning with the handling of individual matters and the establishment of fundamental patent concepts, he assisted the client’s internal personnel in understanding specification drafting and filing strategies, thereby helping the client gradually build its patent management capabilities. Over years of collaboration, the client’s team became better equipped to discuss technical matters and filing directions, and the two sides developed a strong relationship of mutual trust and understanding. For Roger, supporting clients as they build intellectual property capabilities from the ground up is one of the most rewarding aspects of patent practice.
As his practical experience has grown, Roger has taken on team management and talent development responsibilities, translating his case experience into review standards and training methods. He places importance on his colleagues’ technical backgrounds, professional foundations, and work results. He also believes that patent practice requires sustained focus and long-term accumulation of expertise. His management approach therefore balances quality requirements with appropriate flexibility, with the aim of enabling talented professionals to continue developing within a healthy and sustainable work rhythm, while strengthening the team’s overall professional capabilities.
Outside work, Roger enjoys hiking and exercise, which help him reflect, relieve stress, and maintain his physical well-being. He views patent practice as a marathon: success lies not in short bursts of effort, but in steadily building expertise, maintaining sound judgment, and creating trustworthy value for clients in every matter.
Sam entered the intellectual property field after careful consideration of how to apply a technical background beyond traditional industry roles. Trained in Materials Science and Engineering with a particular focus on semiconductor materials, Sam earned both bachelor’s and master’s degrees from the Department of Materials Science and Engineering at National Taiwan University.
During graduate studies, Sam explored various career paths within the technology industry but found the typical long-hour working model less appealing. Around that time, Sam took several introductory courses in intellectual property law—particularly patent law—which sparked an interest in the intersection of technology and law. Concurrently, the Taiwan Intellectual Property Office was recruiting R&D substitute service personnel to serve as patent examiners. Sam was drawn to patent practice because it allows deep engagement with cutting-edge technology while also involving close collaboration with people and legal reasoning. With this motivation, Sam chose to pursue a career in patent law, hoping to help fellow researchers—including classmates, seniors, and juniors—protect their innovations and secure meaningful technical and legal rights.
At present, Sam advises clients on both patent and trademark matters. Several clients come from Sam’s academic network, including former classmates and colleagues. This has allowed Sam to take an initial step toward the original interdisciplinary goal of bridging research and intellectual property practice. Looking ahead, Sam hopes to continue expanding these relationships and supporting more researchers as they translate technical achievements into protected intellectual assets.
One of the most formative experiences in Sam’s career to date was the first involvement in patent litigation, where Sam participated directly in court proceedings to advocate for a client’s rights. While patent practice often centers on drafting specifications and defining claim scope, this experience made the legal dimension of the role particularly tangible. Seeing how patent specifications form the foundation of infringement analysis and courtroom argument reinforced the responsibility carried by patent professionals—to address both technical accuracy and legal strategy simultaneously. It also highlighted the importance of anticipating how readers without technical backgrounds, such as judges, may interpret technical disclosures.
This experience has significantly shaped Sam’s professional approach. Unlike engineering research, which often seeks a single optimal or correct answer, legal analysis requires evaluating multiple perspectives and constructing reasonable arguments under uncertainty. As a result, Sam places strong emphasis on considering all plausible interpretations and dispute scenarios early in a case, ensuring that both legal positions and technical explanations remain robust, predictable, and within a controllable scope.
Sam believes that one of the firm’s key strengths lies in transparent and pragmatic communication with clients. The team aims to clearly explain success probabilities, advantages and disadvantages, and what strategies are feasible or infeasible, rather than fostering overly optimistic expectations. This approach enables clients to make informed decisions and helps establish a foundation of long-term trust.
Outside of work, Sam has been an active badminton player since student years and continues to play at least once every one to two weeks. Sam previously participated in firm badminton activities and friendly matches with colleagues. In recent years, Sam has also taken up golf, tennis, and alpine skiing as a season pass holder. Through sports, Sam enjoys meeting people from diverse backgrounds and views these activities as valuable opportunities for cross-disciplinary and international networking.

In the field of intellectual property, technology and law are never parallel lines; rather, they require precise translation between two professional disciplines. For Director Chen Chih-Ming, the work extends beyond patent filing and prosecution. It is a professional practice centred on one question: how to secure the greatest possible value for clients.
Director Chen’s professional training began in science and engineering. Like many of his peers, he considered a career in the technology industry. However, after closely observing its working environment, he began to reconsider what he wanted his career and life to look like.
“I realised that while the technology industry offered stable prospects, its pace was extremely demanding, and work could intrude on one’s life at any time. I began to ask myself whether that was the kind of life I wanted in the long run.”
A conversation with a former classmate working at a patent firm introduced him to patent practice—a field that combines science and engineering with law. He found that its work style suited his preference for independent work and in-depth thinking. This marked the beginning of his professional journey in intellectual property, a field in which he has continued to build his expertise ever since.
For many people trained in science and engineering, the logic of “right is right and wrong is wrong” is deeply ingrained. Patent practice, however, requires a different way of thinking. “Legal reasoning is inherently relative. The same technology can lead to entirely different outcomes depending on how it is argued.” The core challenge of patent work lies in translating technical logic into flexible legal reasoning. It requires not only technical analysis, but also strategic planning and the ability to construct persuasive arguments.
Even in cases that initially appear to have been fully disclosed in the prior art and to offer little prospect of success, a detailed analysis may reveal distinctions that create room to pursue protection. This ability to move beyond an initial impression and examine the technical details in depth is a key element of the value patent professionals provide.
Director Chen sees patents not merely as technical documents, but as a highly specialised service. “Our work is to translate a client’s technology into documents that the patent authority can understand and that carry legal effect.”
Accordingly, he emphasises two core principles in leading his team: an evidence-based approach, under which all technical content must be fully and faithfully disclosed to avoid validity issues caused by insufficient disclosure; and a client-centred approach, under which professional judgment must be balanced with the client’s actual needs and the technical feasibility of the matter.
Among the many matters he has handled, Director Chen recalls a patent case transferred from another firm. The claimed invention was highly similar to existing technology, and its prospects initially appeared limited. Rather than stopping there, he led the team in re-examining the technical details, identifying distinguishing features, and recommending that the client provide simulation data to substantiate the technical effect. He also arranged an interview with the examiner to communicate directly on the issues. Through a comprehensive strategy and clear explanation during the interview, the team ultimately persuaded the examiner and secured the patent for the client.
When discussing Taiwan Advance’s strengths, Director Chen highlights the firm’s flexibility and tailored service. Compared with larger organisations, Taiwan Advance can respond more quickly to clients’ needs and offer a range of collaborative approaches, including real-time online or in-person discussions, on-site support and technical communication, and service strategies adapted to the needs of each matter. Under this model, patent work is not simply about delivering documents; it is also a process of building trust and long-term client relationships.
For newcomers to the field, Director Chen believes that the greatest challenge is often not professional knowledge, but a shift in mindset. By learning from a large number of practical cases and from the experience of senior professionals, newcomers can gradually develop a new framework for judgment. He also encourages them to look beyond immediate difficulties and consider their own long-term development.
Outside work, Director Chen devotes much of his time to family and personal faith. For him, religion is not only a central part of life, but also a source of values that helps him maintain stability and balance in both work and life.
Sun has an interdisciplinary academic background spanning electronics, information technology, and biomedical engineering. Through this course of study, she developed the ability to understand technical logic and integrate perspectives across different professional fields.
During graduate school, Sun conducted research under a professor in the electronics field. She initially planned to pursue a career in the semiconductor industry and secured an internship at a semiconductor company. This experience gave her a clearer understanding of industry practice and her own career aspirations. After taking patent-related courses and participating in a collaborative laboratory project to develop patent-searching and portfolio-planning software, she realised that patent practice combines technical understanding, logical analysis, and strategic thinking. It also offered an opportunity to apply the strengths of her interdisciplinary background, leading her to pursue a career in intellectual property.
Sun believes that the challenge of patent practice lies in rapidly understanding a wide range of emerging technologies and translating complex technical concepts into claims and legal documents capable of receiving protection under patent law. At the same time, this is precisely where the work creates its greatest value: through precise analysis and drafting, complex technical disclosures can be transformed into intangible assets that can be strategically protected, deployed, and commercially leveraged.
In her work, Sun places particular emphasis on seeing matters from the client’s perspective. When handling a case, she seeks to understand the problem a technology was developed to address, how it is implemented in practice, and how it may be applied in the future. By understanding the underlying rationale for an invention, she can identify its true technical core, recognise gaps or points requiring further clarification in the disclosure, and develop a more complete patent strategy. She also considers market conditions and potential competitive scenarios, including possible design-around approaches that competitors may take, in order to develop protection strategies with greater defensive strength.
In recent years, many clients have begun using AI to assist with the organisation of invention disclosures. Sun recognises that AI can improve the efficiency of information processing; however, its output remains dependent on the information already provided. It may not identify unstated technical features, patent-law risks, or potential design-around strategies that competitors may adopt in the future. She also emphasises that when publicly available AI tools are used, particular care must be taken to protect confidential core technical information.
Sun is committed to continually strengthening her technical understanding and patent strategy capabilities. Through rigorous reasoning, communication that remains closely aligned with clients’ needs, and sensitivity to market applications, she seeks to help every innovation obtain protection that is both valuable and competitively effective.
