Final answer:
State courts handle a variety of cases, but some cases have exclusive jurisdiction in federal courts. These cases include those involving foreign governments, bankruptcy, patent infringement, and interstate activities. However, there can be overlapping jurisdiction between state and federal courts if a case involves federal law or constitutional issues.
Step-by-step explanation:
State courts handle a wide range of cases, including crimes, civil matters, and family issues. However, there are certain cases that fall under the exclusive jurisdiction of federal courts, such as those involving foreign governments, patent infringement, and bankruptcy. Additionally, cases that arise from activities across state lines or involve the United States as a party are heard in federal courts. However, there are instances where cases may be heard in both state and federal courts, especially if they involve federal law or constitutional issues.
