Infringement is the unauthorized violation of rights protected by intellectual-property law. In plain language, it means using protected material, marks, inventions, or protected confidential information in a way the law forbids.
Why It Matters
The term matters because many IP disputes are framed first as infringement questions. The analysis then turns on what right existed, whether the defendant’s conduct fell within that right, and whether any defense or exception applies.
Where It Appears
The term appears in copyright suits, trademark disputes, patent litigation, platform notices, cease-and-desist letters, and settlement negotiations.
Practical Example
A competitor copies protected software code into its own product without permission. The rights holder may allege infringement and seek damages or an injunction.
How It Differs From Nearby Terms
