Copyright – Validity – Ideas and Expression

activein force · 2025-12-01 – presentact-effective-date

Copyright protection doesn’t extend to all the elements of a copyrighted

work. Elements covered by the copyright protection are called “protected matter,”

and non- covered elements are “unprotected matter.” Because unprotected matter

isn’t entitled to copyright protection, another author may copy it.

There are various types of unprotected matter. They include:

• a portion of the work that isn’t original to the author;

• a portion of the work that’s in the public domain; and

• an idea, concept, principle, discovery, fact, actual event, process, or

method contained in a work.

A work that’s “in the public domain” is one that does not have copyright

protection, so anyone may use all or part of it in another work without charge.

In copyright law, it’s important to distinguish between the ideas in a work

and the author’s expression of the ideas. The ideas in a work are unprotected

matter. But an idea must be expressed in some way, and the expression or means of

expression of an idea is protected matter.

For example, copyright law doesn’t protect the idea of a determined captain

hunting a giant whale. But copyright law does protect the particular expression of

this idea in the book Moby-Dick.

Put another way, the author of a work has no exclusive right to the

underlying ideas, concepts, principles, discoveries, facts, actual events, processes,

or methods contained in a work. But the author’s copyright does extend to the

means by which those are expressed, described, depicted, implemented, or

otherwise communicated in the work.

• a portion of a work that isn’t original to the author;

• a portion of the work that’s in the public domain; or

• an idea, concept, principle, discovery, fact, actual event, process, or

method expressed or described in a work, you should exclude that

material from the protected matter [name of plaintiff]’s copyright -

infringement claim can be based on.
