Which act number provides protection for trademarks and service marks?

• A. RA 5455
• B. RA 6136
• C. RA 166
• D. RA 5186

Answer: (C)

The important idea is that trademarks and service marks are protected by a law that defines what can be registered, who has the rights to use the mark, and what remedies exist for infringement. The act identified in this context sets up the framework for registering marks used in commerce to distinguish goods (trademarks) and services (service marks), granting the owner exclusive rights to those marks, and outlining penalties for others who use a confusingly similar mark. It also typically covers the registration process, duration of protection, and grounds for refusal or cancellation.

So, the act number in question is the one that specifically addresses marks and their protection, including registration and enforcement. The other act numbers refer to different areas of law and do not provide the protection described for trademarks and service marks.
