Yes, you can absolutely sue someone for using your trademark without permission if their use is likely to cause consumer confusion, deception, or mistake about the source of goods/services, or if they dilute a famous mark; lawsuits aim to get an injunction (stop them) and damages, but it's often expensive and first steps usually involve cease-and-desist letters. To win, you must prove you own a valid mark, have priority, and the infringer's use creates a "likelihood of confusion" (similar marks on similar/related products) or dilutes a famous mark, with federal or state court being options.
