Final answer:
The Lanham Act is the principal federal law on trademarks in the United States, and it does not remove federal jurisdiction over trademark law.
Step-by-step explanation:
The Lanham Act is the principal federal law on trademarks in the United States. It was enacted to provide strong and consistent protection for trademarks. The act did not include the feature of removing federal jurisdiction over trademark law. In fact, trademark law falls under federal jurisdiction and is overseen by the United States Patent and Trademark Office (USPTO).
