The "patents and copyrights" clause.
Congress has the power to issue copyrights and patents. Patents and Trademarks are handled by the Patent and Trademark Office, which is part of the Department of Commerce. The Copyright Office is part of the Library of Congress.
Ordinance power gives the President of the United States the power to run the executive branch of the government. It allows him to issue executive orders.
No representation in Congress
No. In the U.S., the Constitution places all authority for borrowing and spending in the hands of Congress. The Constitution does not place a limit on the amount that the country may borrow. Because it was inconvenient for Congress to get involved every time the Treasury needed to issue a security, Congress passed a law in 1917 which allows the Executive Branch, specifically the U.S. Treasury, to borrow money as necessary, provided that the total amount borrowed remains within a limit set by Congress. Currently (July 2011), that limit is set at $14.3 trillion.
The ordinance power of the president allows him to create laws when immediate action is required and Congress is not in session. This is meant for emergency situations only, and most lawmaking should be left to the Congress to ensure that checks and balances are in place.
The Constitution does not specify: it just says "Congress." Copyright protection is now automatic, but formal registrations are still handled by the Copyright Office, which is part of the Library of Congress.
Congress was not allowed to make a law banning the slave trade before 1808.
James Madison report was able to make the congress to issue a formal call to the states for a constitution convention.
The president does not have the power to initiate laws-- only Congress can do that.
