A counterfeit is an imitation that is made usually with the intent to deceptively represent its content or origins. The word counterfeit most frequently describes forged currency or documents, but can also describe clothing, software, electronic stock shares or certificates, pharmaceuticals, watches, or more recently, cars and motorcycles, especially when this results in patent infringement or trademark infringement.
