Copyright Infringement of Protected Expression

Copyright infringement is unauthorized use of protected expression in a way that violates the copyright owner's exclusive rights.

Copyright infringement is unauthorized use of protected expression in a way that violates the copyright owner’s exclusive rights.

Copyright infringement matters because it can affect copying, distribution, public display, performance, adaptation, and digital posting of protected works. The analysis often turns on what was copied, whether the copied material is protectable expression, and whether a defense or license applies.

Registration, damages, takedown procedures, and fair use can also affect the dispute.

Copyright infringement appears in content disputes, software copying, photography use, publishing disputes, music and video disputes, DMCA takedowns, licensing negotiations, and federal lawsuits.

Practical example

A company copies a photographer’s image from a website and uses it in an advertisement without permission. The photographer may allege copyright infringement.

Copyright infringement differs from general infringement because it concerns copyright rights specifically. It differs from trademark infringement because trademark law focuses on source identification rather than protected creative expression.
