Competition Law

In recent decades, changing views on market competition and the active enforcement from competition law authorities worldwide have made competition law into a legal field that no enterprise can afford to ignore in their business operations.

Lee, Tsai & Partners have successfully represented our clients in many landmark competition law cases. Our firm has extensive experience providing professional legal services to our clients on competition law issues ranging from concerted action, abuse of monopoly position, merger approvals, vertical restrictions (price-based or otherwise) to other unfair competition conduct issues. We have also successfully assisted our clients in resolving competition law matters that involve intellectual property rights, such as standard-essential patents (SEPs) and abuse of patent rights, as well as assisting competition law matters arising from other jurisdictions, such as responding to competition investigations by authorities in the US and the EU.
