Taiwan IP Counsel
Your IP counsel
in Taiwan.
Chung Cheng is a Taiwan intellectual property firm. We act as the local counsel foreign firms and rights holders rely on to get matters done in Taiwan — patent and trademark prosecution, trade secret and copyright protection, corporate IP, and litigation before the Intellectual Property and Commercial Court (IPC Court). Where a filing agent stops at the application, we bring the examination depth, judicial experience, and English-language working practice that decide whether your rights actually hold in Taiwan.
Why local Taiwan counsel
Taiwan depth, beyond the filing.
Foreign firms do not need another filing agent in Taiwan — they need counsel who can carry a matter through Taiwan's own standards. A trademark registrable elsewhere may be refused in Taiwan on distinctiveness; a Taiwan patent claim survives or fails on how its examination and amendment practice is handled; an IP dispute turns on the technical examination procedure of a specialist court. That is the work we do.
We are built to be the Taiwan end of your matter: filings prosecuted to Taiwan examination standards, disputes argued by counsel with first-hand judicial experience, and every step run in English with foreign counsel. Where it helps you decide how to file in Taiwan, we will also map how Taiwan differs from CNIPA and other neighboring offices — not to sell a multi-jurisdiction strategy, but so your Taiwan rights are built to hold.
Beyond filing

Our team combines Taiwan patent and trademark attorneys with former IPC Court and High Court judges, US- and Italy-qualified counsel, and multilingual cross-border practitioners. Jack (Chieh-Kai) Yang is a Taiwan Patent Attorney (since 2017) and a Taiwan Trademark Agent (since 2014), and passed the USPTO Patent Bar in 2020 (not registered). He prepares draft US applications and office-action responses in Taiwan for registered US practitioners, who review, sign and file them and handle all communication with the USPTO, including examiner interviews. Preparing the drafts in Taiwan reduces translation drift and examiner-communication cost.
