We are encouraged by the success and recognition we have achieved so far, and our goal is to always increase our efforts in order to meet the strictest professional standards and our clients’ every request in the future.

Our legal and technical professionals: We employ more than 280 professionals, including attorneys at law, patent attorneys, trademark agents, technical specialists and legal consultants, in four offices across Taiwan. These professionals are experienced in providing customized solutions on a cost-effective basis. Many of them hold postgraduate degrees, including PhDs, in either legal or technical fields from top institutions in Taiwan or overseas. Their outstanding academic credentials are enhanced by active engagement in advanced professional activities, from writing IP textbooks and articles to lecturing IP courses held by the government and academic institutions.

Every professional of the firm is proficient in at least one foreign language, including English, German and Japanese; while some of them are multilingual. Tai E’s professionals are trained in various categories of law and specialize in a wide range of technical fields, including pharmacology, chemistry, biotechnology, immunology, computers and software, electronics, semiconductors, physics, mechanical engineering and industrial design. Depending on the nature of a case, our professionals collaborate with each other to ensure that the best result is achieved for each client.

Tai E also offers a wide range of consulting and educational programs to local enterprises and is frequently consulted by government agencies. A number of our professionals have been invited to participate in public hearings regarding amendments to IP laws or regulations, such as the Trademark Act, the Patent Act and the Examination Guidelines. In addition, Tai E has played an active role in a number of professional organizations and has provided pro bono legal service at the Taiwan Intellectual Property Office.

Simple philosophies, solid commitments: We vow to provide services that exceed our clients’ expectations, catering to all requests.

Our reasonable fees guarantee the value of our services, and we ensure the best staff with the right expertise will be appointed to the task.

TESTIMONIAL: A great firm and always responsive to clients’ inquiries.

Our client was sued for infringement of an invention patent owned by the plaintiff, and the plaintiff demanded our client to pay damages in the amount of NTD 20,000,000 (about USD 666,667). On behalf of the client, Tai E successfully persuaded the IP Court in the first and second instances that the patent in dispute shall be invalidated for lack of novelty, and the judgments were then rendered in favour of our client (the defendant) respectively on March 26, 2019 and May 21, 2020. The plaintiff then filed an appeal with the Taiwan Supreme Court, but the Court dismissed their appeal on May 12, 2022. This case has become irrevocable and binding.
