Copyright is a legal right created by the law of a country that grants the creator of an original work exclusive rights for its use and distribution. This is usually only for a limited time. The exclusive rights are not absolute but limited by limitations and exceptions to copyright law, including fair use. A major limitation on copyright is that copyright protects only the original expression of ideas, and not the underlying ideas themselves.
Copyright registration involves filing the proper form obtained from the Goverment Department. Copyright Office and submitting it with the required fee and work sample. The Copyright Office does not compare new works with those previously registered by others, and only serves to provide dated evidence in cases of infringement or misuse. When infringement lawsuits are filed, the courts make the final ruling by comparing the works in question. When misuse suits arise, the court relies on copyright registration dates to prove ownership.
