Which type of case is typically under exclusive federal jurisdiction?

• A. Contract dispute between private parties in state court.
• B. Criminal case under state law.
• C. Patent dispute.
• D. Divorce proceeding in a state family court.

Answer: (C)

Patent disputes fall under exclusive federal jurisdiction because patent law is created and governed by federal statute, and Congress has given federal courts the sole authority to interpret and decide patent claims. This ensures a uniform application of patent rights across all states, avoiding the variability that could come with disparate state rules. In practice, cases involving patent issues are brought in federal court and are not within the usual reach of state courts. By comparison, a contract dispute between private parties is typically handled in state court, since contract law is primarily a matter of state law unless a federal question or other federal basis is involved. A criminal case under state law belongs in state court because it concerns violations of state statutes, not federal law. A divorce proceeding in a state family court is likewise a matter of state family law and is generally within state jurisdiction.
