Will your IP protection provide the protection you expect

Companies protect their intellectual property (IP) in a variety of ways. They can use copyrights, trademarks, patents or a combination. Each provides certain types of protection for certain types of IP under certain circumstances. The Mitel company put its command codes for its call controller in its copyrighted programming manual. Iqtel used these codes to be compatible. Iqtel was supported by the courts on the basis of fair use.
