Trademark Agent
Our firm was co-founded by trademark and patent partners in March 2010, originally under the name “Surpass Intellectual Property Office.” On December 25, 2024, we were restructured and renamed EXCTM International IP Office, marking our 15th anniversary.
We fully recognize that patents and trademarks are two distinct areas of expertise. Since entering the intellectual property field 28 years ago, our founder has focused on trademark applications and related practices, upholding the principle of professional specialization. With a commitment to continuous development in the trademark domain, we strive to assist both domestic and international clients in building and protecting their brand value.
To date, we have handled over 3,500 trademark cases before the Taiwan Intellectual Property Office (TIPO). Over the past five years, our approval rate for trademark applications has reached 97%, significantly higher than the official average approval rate of 87%. This demonstrates the importance we place on the quality of every case we manage.
At our firm, we adhere to a thorough and client-centered process to ensure high-quality outcomes:
We treat every case with the same dedication as if it were our own. With this mindset, we strive to secure smooth approvals and protect our clients’ rights to the fullest extent.
Repeating the same task for decades does not necessarily embody the spirit of craftsmanship. For us, true craftsmanship means constant refinement in the everyday, striving to perfect a single pursuit. The late director Hugh K. S. Lee once said: “If a person can do one thing well in their lifetime, that is fulfillment.”
At EXCTM, we believe that patents represent the fusion of technology and law, while trademarks combine marketing strategy with legal systems—both requiring true expertise. Unlike the industry norm of “one person handling many roles,” we adhere to specialization, refusing to be reduced to mere clerical processing.
For 28 years, we have dedicated ourselves exclusively to trademark practice—a path that may seem ordinary, yet requires meticulous judgment and expertise. To us, professionalism is not measured by how much money is earned, but by wholehearted commitment—the pursuit of true excellence.
