Trademark and Other IP Litigation
Trademark and Other IP Litigation
In our trademark and general IP litigation practice, we represent brand owners and defendants in litigation where different types of trademarks and intellectual property rights are asserted. We have acted for a wide variety of clients and products, ranging from luxury goods to industrial products to toys to restaurants. In all cases, we understand that a client’s brand may be one of their most valuable assets and we strive to implement a litigation strategy to achieve the client’s specific business goals.
