If I trademark my company/product name, does that mean nobody else can use it?

Trademarking your company or product name gives you exclusive rights to use it in connection with your goods or services. This prevents others from using a similar name that could cause confusion among consumers. However, trademarks only protect the name within specific industries or regions, so if someone uses a similar name in a different context, it may not be considered infringement. Additionally, trademarks need to be actively enforced to remain effective.
