Using a Patented Invention Without Permission Is Known As?

• A. Faking
• B. Plagiarism
• C. Piracy
• D. Infringement

Answer: (D)

Patent infringement happens when someone uses a patented invention without the permission of the patent holder. A patent grants the inventor exclusive rights to make, use, sell, or import the invention for a set period, so any unauthorized use that falls within the patent’s claims is an infringement. This term specifically captures the legal violation of patent rights, whether you’re manufacturing the device, using it in a process, selling it, or importing it without a license. Other terms don’t fit this situation: faking and plagiarism relate to deception or copying in other contexts, and piracy is typically about unauthorized copying or distribution of copyrighted material rather than patents. If there’s a license, the patent has expired, or the use isn’t covered by the patent claims, it wouldn’t be infringement.
