Suppose you work for a reusable space rocket manufacturer and transporter called
OrbitY. After spending millions (or billions) of dollars in internal research and
development, OrbitY has come up with a rocket engine that can be reused between
flights. This reusable rocket engine gives OrbitY a strong competitive advantage
over traditional space companies as OrbitY can now transport cargo to space for a
fraction of the cost. Stiff competition has now risen all over the world with
companies wanting to apply the same principle of reusable rocket engines. Which
of the following mechanisms would best protect OrbitY's reusable rocket engine
technology from being copied by a competitor?
A. Copyright
B. Trademark
C. Patent
D. Trade secret
D. Trade secret

recognition treaty.
C. Individually file for a patent in every other foreign country where they want
