Your Taiwan IP local counselfor foreign companies and overseas firms

WISECODE IP Group is a Taiwan-based intellectual property firm that acts as local counsel for foreign companies and overseas IP firms. We handle Taiwan trademark and patent filing, office-action responses, oppositions and invalidations, freedom-to-operate (FTO) analysis, and IP risk strategy — with direct, partner-level attention and clear English and Japanese communication. Beyond Taiwan, we also handle China trademark and patent filing and China patent FTO through our established China partner, and our team includes a qualified PRC patent agent (中國專利代理人). Foreign applicants without a domicile or business in Taiwan must appoint a local agent, and WISECODE is built to be that dependable Greater China partner.

Why foreign applicants need Taiwan local counsel

Taiwan operates its own intellectual property system through the Taiwan Intellectual Property Office (TIPO), separate from China and from international filing routes. A foreign company that has no domicile or business establishment in Taiwan generally cannot file directly — it must appoint a Taiwan-based agent to act before TIPO.

Beyond the formal requirement, local counsel manages the parts of the process that decide outcomes: Traditional Chinese translation of names, specifications and claims; substantive examination and office-action strategy; and strict deadline management. Getting these right is the difference between durable protection and an avoidable refusal.

What we handle

  • Trademark prosecution and clearance searching
  • Patent filing and prosecution — invention, utility model and design
  • Office-action and refusal responses
  • Oppositions, invalidations and non-use cancellations
  • Freedom-to-operate (FTO) and infringement / validity analysis
  • Portfolio management — renewals, annuities and recordals
  • IP due diligence for investment, M&A and distributor agreements
  • China trademark and patent filing, and China patent FTO, through our established China partner
  • Technical and legal translation — English / Japanese to Traditional Chinese

Greater China coverage: Taiwan and China

Foreign companies and overseas firms often need Taiwan and China handled together. Beyond our Taiwan practice, we file China trademarks and patents and conduct China patent FTO through our established China partner — so you can coordinate Greater China IP through a single point of contact.

Our team includes a qualified PRC patent agent (中國專利代理人), giving you informed China patent judgment alongside our Taiwan local counsel.

Common cross-border pitfalls

  • Assuming a PCT application can enter the national phase in Taiwan — it cannot.
  • Filing a Taiwan trademark without appointing the required local agent.

  • Missing the Paris Convention priority window when transitioning from a home filing.
