“Copyright only applies to Expressions”
The core principle of copyright law is that it only applies to expressions and in short this itself is the inception of the Idea-Expression Dichotomy.
The idea-expression dichotomy was formulated to ensure that the expression of an idea (i.e., expression), rather than the idea itself, is protected. This doctrine is widespread in the United States and is not entirely alien to Indian jurisprudence. Courts have repeatedly held that ideas themselves are not copyrightable.
Copyright covers only the expression of ideas. An idea is the formulation of an idea on a particular topic, and an expression is the realization of that idea. Many people may come up with the same idea themselves, but they can only claim copyright in the form of the expression of that idea. Such expressions must be specific sequences of words, numbers, or other forms. Therefore, such a principle makes it possible to use multiple expressions for the same idea.
