I want to know the answer to the following question:
What type of property are trademarks and copyrights?
All the background I'm provided with is that "During the 18th and 19th centuries, federal law traditionally focused on areas where there was an express grant of power to the federal government in the federal Constitution, like the military, money, foreign relations (especially international treaties), tariffs, intellectual property (specifically patents and copyrights), and mail.". Is that enough to answer the question?
Answer: yes
