Federal courts have jurisdiction over cases involving federal laws, the Constitution, disputes between states, and cases involving the United States government.

The authority of a court to rule on certain cases is known as the jurisdiction of the court. State courts have jurisdiction over matters within that state, and different levels of courts have jurisdiction over lawsuits involving different amounts of money.

The key differences between state and federal court systems in the United States are the types of cases they handle, their jurisdiction, and the laws they apply. State courts primarily handle cases involving state laws and issues, while federal courts handle cases involving federal laws and issues. Federal courts have jurisdiction over cases involving federal laws, the U.S. Constitution, disputes between states, and cases involving parties from different states. State courts have jurisdiction over cases involving state laws, local ordinances, and disputes between residents of the same state. Additionally, federal courts are established by the U.S. Constitution and have limited jurisdiction, while state courts are established by state constitutions and have broader jurisdiction.
Federal courts have jurisdiction over cases where the parties are located in different states; and they have have jurisdiction over "federal questions" such as trademark law, which is regulated by the federal government, not the state; and Federal courts have jurisdiction over disputes between the states.
Federal courts have jurisdiction over four main types of cases: cases involving federal law, cases involving the U.S. Constitution, cases in which the U.S. government is a party, and cases between citizens of different states (diversity jurisdiction) where the amount in controversy exceeds a specified threshold. These cases ensure that federal laws and constitutional rights are upheld uniformly across states. Additionally, federal courts may hear certain specialized cases, such as those involving maritime law or bankruptcy.
Federal courts have jurisdiction over cases involving federal laws, the Constitution, or disputes between parties from different states. State courts, on the other hand, have jurisdiction over cases involving state laws and disputes between parties within the same state. Federal courts have authority to interpret and apply federal laws, while state courts have authority to interpret and apply state laws.
State courts hear any and all cases having to do with the laws of their particular state which were passed by their state legislature. They do not hear cases involving the laws of other states nor do they hear Federal cases.
The Supreme Court has original jurisdiction over disputes between the states; it also has original, but shared, jurisdiction over cases involving ambassadors (although the latter class of case is not automatic). Congress cannot remove the Supreme Court's original jurisdiction; that action can only be accomplished through constitutional amendment.
The US Supreme Court has exclusive original jurisdiction over cases involving disputes between the states. This is the only place such cases are heard.
Federal courts have exclusive jurisdiction over several categories of law including: Trademarks, copyrights, maritime law, conflicts between the states, when you want to sue your state or an official of it, violations of federal laws which do not have a state equivalent, cases that involve foreign governments or citizens.
