Firm Overview: 

Tsai, Lee & Chen is a top-tier IP law firm based in Taipei, Taiwan with more than 180 IP professionals and lawyers.

Founded in 1995 by Thomas QT Tsai, who was also the founding president of Taiwan Patent Attorneys Association (TWPAA), the firm boomed with the advent of Taiwan’s high-tech industrialisation. The firm has since developed a full service IP law firm encompassing all areas of IP from prosecution to litigation, garnering tremendous trust from its reputable domestic and international clientele.

While the firm primarily practices as an IP boutique, its lawyers also encompass legal skill to resolve corporate disputes and company tax issues. Its expertise aims to deliver tailored and integrated IP and legal solution in order to comprehensively be of service to its clients.

The firm’s patent expertise is led by 22 patent attorneys licensed in both Taiwan and China, while another 38 patent attorneys licensed in either Taiwan or China. Their technical backgrounds encompass the fields of semiconductors, consumer electronics, thin film transistor liquid crystal display technology, mechanical and electrical engineering, optics, artificial intelligence, financial technology, computer hardware and software, telecommunications, biochemistry, pharmaceuticals, business methods and information technology.

The firm’s trademark team, along with its attorneys at law, is known for its high level of attentiveness and responsiveness towards each of its clients and cases. In addition to specialising in Taiwanese trademark practice to serve its international clients, the firm's seasoned professionals also manage global trademark portfolios and disputes for domestic clients. The team enjoys an outstanding success rate in overcoming citations, oppositions, invalidations and infringement litigations.

IP Filing and Portfolios Managed 

Regardless how the IP Office filing figures fluctuate, the firm remains a dynamic momentum to grow. It files more than 6,500 patent applications globally and annually, while 1700 new trademark filings from domestic and international clients.

Litigation & Dispute Resolution 

The firm has a record of handling many landmark cases at Taiwan IP Court. The types of litigation and disputes range from trademark, patent, copyright, unfair competition to breach of contracts. The team is sophisticated in complex trademark enforcement issue, patent invalidation and infringement as well as non-infringement analysis and declaratory actions.

The firm forms a strategic alliance with a Chartered Accountant and the attorney specializing in corporate law and taxation law. This expands the horizon of legal service to resolve corporate disputes and tax issues including the shareholders’ meeting, company management, investment and transaction.
