Information on Practicing Trademark Agents

  1. If you are looking for the information of trademark agents, you can find relevant trademark agents and the status of each case handled by them through the following path: Trademark Search System/Trademark Search (by applicant, case number)/Attorney (Chinese Name).
  2. TIPO has organized and published the information of practicing trademark agents on this website with their consent. The web addresses of the Bar Associations and Certified Public Accountants (CPA) Associations are also provided for reference:
    1. Taiwan Bar Association
    2. Taipei Bar Association
    3. CPA Associations
  3. The one who has been appointed as a trademark agent in 20 or more applications for trademark registration each year in the last 5 years can be listed on this website. TIPO regularly compiles and updates relevant statistics every year, but TIPO does not examine facts concerning qualification or quality of the trademark agents on the list. If relevant information has changed, it is better for the trademark agent to notify TIPO through emails spontaneously. TIPO will update it as soon as possible. If there is any question related to the information on the list, please contact with Mr. Gu with the number 02-23767571, who is going to assist in updating relevant information immediately.

    1. Personal data of trademark agents listed on this website are collected by TIPO based on specific purposes of IPR administration. According to Article 3 of the Personal Data Protection Act, trademark agents can make an inquiry of, review, request a copy of, supplement or correct, and demand the cessation of the collection, processing or use of his/her personal data. When it is necessary, the trademark agent can also request TIPO to erase his/her personal data, unless the processing or use is necessary for the performance of the official duty.
    2. The column of the “certificate number” includes (1) the number of the certificate issued after passing the qualified threshold of the “Proficiency Certification for IPR Practitioners” held by TIPO and TIPA; (2) the number of the attorney’s certificate or the CPA certificate. Whoever wants to refer to the information of trademark agents published on the website should keep an eye on whether the certificate is still valid.
