Taiwan’s IP Experts 2025

15 July 2025

Taiwan boasts a strong legal market, thanks in part to its leading role in semiconductor and other high-tech manufacturing. The legal market in Taipei – and, indeed, elsewhere around Taiwan – is robust and competitive, giving it outsize strength for a jurisdiction with a working age population of just 16.55 million people.

The Taiwan Intellectual Property Office – and, indeed, the government generally – has made significant investments in the jurisdiction’s intellectual property regime to help maintain its role in the high-tech world. TIPO’s 2024 Annual Report, published in July 2025, reported that the average first office action pendency and the average disposal pendency for invention patents were 8.4 and 14.2 months, respectively, while the average first office action pendency and the average disposal pendency for trademarks were 6.1 and 7.4 months, respectively. It reported that 91.5 percent of patent applications and 89.2 percent of trademark applications were made online.

In 2024, TIPO implemented the Accelerated Examination Program for Reexamination (AEPRe) to grant patents in as fast as 15 days, and launched brand new AI-assisted trademark image search to streamline searches for identical or similar trademarks. It has promoted Taiwan Patent GO since April 2024 to showcase excellent patents in international exhibitions and facilitate business opportunities.

The semiconductor industry continues to receive significant attention in invention patent applications, with Applied Materials and ASML Netherlands ranking among the top foreign patent applicants, with Applied Materials reclaiming the top position from Samsung Electronics, which has fallen to second place. Materials science and the chemical industry are also noteworthy, with companies including Nitto Denko and Shin-Etsu Chemical and Lam Research among the top filers. In the electronics and technology industries Qualcomm and Huawei Technologies lead in applications filed.

On the domestic side, TSMC maintained its lead in patent applications in 2024, ranking first in domestic invention patent applications for nine consecutive years. Nanya Technology and United Microelectronics are also among the top filers. AU Optronics and Innolux rank highly in optoelectronics, with Innolux’s patent application volume reaching a record high. In the electronic components and information technology sectors, companies including Inventec, Realtek Semiconductor, Acer and Foxconn Technology Group continue to engage in electronic manufacturing and OEM fields.

Computer and technology products (Class 9) remain the most applied trademark category by foreign companies, confirming that international corporations continue to value trademark protection for technology products sold in the Taiwanese market.

Foreign brands are optimistic about potential development of the Taiwanese consumer goods market, with trademark application volumes for cosmetics and cleaning agents (Class 3), clothing and footwear (Class 25), and leather products, artificial leather, and bags (Class 18) all showing significant double-digit growth in 2024.

Domestically, advertising, business management and retail wholesale services (Class 35) are the most applied trademark categories in the country; trademark application volume in the food and beverage-related industries is also high, with what a law firm Lee and Li calls “a significant number of applications” for restaurants and accommodations (Class 43) and for coffee, tea, pastries, etc. (Class 30). “This indicates fierce competition in Taiwan’s dining market and a growing awareness among businesses regarding trademark protection,” the firm said in analysis posted on its website.

It is against this dynamic backdrop that we turned to IP professionals in the region in order to understand better what clients need today. Asia IP asked a large number of professionals – mostly in-house counsel and corporate legal managers – what they were looking for from their legal service providers. From their answers, we have compiled our list of 50 Taiwan IP Experts, those lawyers who understand just what their clients need and are able to provide them with the best practical advice.

Taiwan’s legal market has shown signs of fragmentation; there is more than a smattering of new and upcoming firms represented on our list. In fact, an impressive 32 different firms placed at least one lawyer on the list, from small boutiques to global law firms.

Tsai, Lee & Chen placed four lawyers on the list (Candy K.Y. Chen, Crystal J. Chen, Victor S.C. Lee and Jesse K.Y. Peng), while Lee and Li (Hsiu-Ru Chien, Gloria Lu and Ruey-Sen Tsai), TIPLO (H.G. Chen, J.K. Lin and Johnny Yang) and Rich IP & Co. (Russell Horng, Jason Hung and Cross Liu) each placed three lawyers on the list.

Most of the lawyers named to our list have multiple practice specialties. Many of them are litigators, while others concentrate on prosecution work or provide strategic advice.

All of them have something in common: they are experts in their fields and, in one way or another, they provide extra value for their clients. They are Asia IP’s Taiwan IP Experts.

Taiwan’s IP Experts is based solely on independent editorial research conducted by Asia IP. As part of this project, we turned to thousands of in-house counsel in Taiwan, China, elsewhere in Asia and around the world, and asked them to nominate private-practice lawyers, including foreign legal consultants, advisers and counsel.

The final list reflects the nominations received combined with the input of the editorial team at Asia IP, which has more than 50 years of collective experience in researching and understanding the legal market in Asia.

All private practice intellectual property lawyers working at law firms in Taiwan were eligible for inclusion in the nomination process; there were no fees or any other requirements for inclusion in the process.

The names of our 50 IP Experts are published here. Each IP Expert was given the opportunity to include their biography and contact details in print and on our website, for which a fee was charged.
