CF Tsai

Managing Partner at Deep & Far

Since 1982 CF Tsai has practised in all stages of IP law – from prosecution to litigation of patents, trademarks, copyright, circuit layouts, trade secrets, unfair competition and licences before the courts in Taiwan and abroad.

Brain waves, perseverance and stamina are considered to be the most important features of a successful character. Intelligent, dedicated and inexhaustible, Mr Tsai strives to keep pace with all relevant knowledge and practices relating to IP law.

Mr Tsai is the first patent practitioner in Taiwan to have a technological and law background and be qualified as a local attorney at law. He has a marine engineering background, having majored in this subject at the National Chiao Tung University. He has been extensively involved in work relating to the mechanical, electric, electronic, civil engineering, chemical, semiconductor and medical fields. In the course of his practice, he completed his law degree at the National Taiwan University and then obtained his master’s in comparative laws from Soo Chow University. Under his leadership, Deep & Far has won services from more than 20% of the top 100 national corporations, in addition to 25% of the high-tech companies in the science-based industrial park located in Hsin Chu.

Mr Tsai believes that clients can discover the value and competence of Deep & Far’s IP services by sending it:

  • a pending or granted patent – the firm will suggest improvements to the claims;
  • a pending patent specification without claims – Deep & Far will draft claims for comparison with the original ones; or
  • an initial disclosure, also sent to the firm the client is using – the client can see which firm provides better claims.
