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. It becomes more comple# in theconte#t of changing technologies, i.e. cinematographic works, sound recording, broadcasting etc which is a combination of different works, also when author does thework in the course of employment. $hen new technologies emerge, different mode of communication simultaneously arise and the e#ploitation of the copyright by wayof assignment %licensing will add economic benefits to the copyright owner and the provisions of assignment and licensing becomes crucial. By amendments Indian Copyright!ct has taken care of such provisions, but still leaving lacunae % the role of &udiciary becomes crucial in interpreting such provisions for effectively protecting the rights of the authors.
