Cruz Marcelo & Tenefrancia (CMT) is a top-tier full-service Philippine law firm with 95 lawyers and 99 support staff. Its multi-awarded intellec- tual property (IP) department is distinguished by its ability to provide the widest range of IP ser- vices, including trade mark prosecution, patent drafting and prosecution, copyright protection, IP litigation, IP commercialisation, and IP valua- tion. CMT is the go-to firm for resolving complex IP issues, particularly in patent litigation. Unlike other Philippine law firms that delegate IP litiga-

tion to their general litigators, CMT’s IP lawyers handle IP litigation, which gives them the com- petitive advantage in IP litigation due to their subject matter expertise. The firm’s lawyers and specialists have strong technical backgrounds in physics, chemistry, and engineering, enabling them to adeptly navigate intricate IP challenges. CMT’s IP team bridges technical expertise and legal skills, which enables the formulation of effective legal strategies in the protection and maximisation of IP rights.
