Copyright protection is given for a work having originality,i.e. it should be from the author and must have minimum degree of creativity. So it is the author who is the real creator of the work thereby first owner of the copyright and Indian law recognizes author as the firstowner of the copyright .But by the term ‘ownership it means it includes not only theauthor ,but also assignee and can even a legal entity even though not defined in the !ct. InBern convention the term !uthor is not defined, instead it says that the person under whose name the work is disclosed, which implies that it is not necessary that always theauthor should be the owner. "owever Indian copyright !ct defines the tern ‘!uthor withrespect to various works, but still leaves some problems.
