Which crime involves stealing a trade secret or making a copy of an article representing a trade secret?

The crime defined in the question specifically relates to the unauthorized appropriation or reproduction of trade secrets. This falls under the umbrella of intellectual property crimes, where protections are established to safeguard proprietary information that gives a business a competitive advantage.

Stealing a trade secret can include actions such as espionage or the illegal copying of a product that incorporates a trade secret, which essentially gives rise to the concept of theft of trademarks. This offense typically addresses aspects of unfair competition and highlights the importance of protecting businesses’ intellectual property from unlawful exploitation.

In contrast, the other options do not directly involve the misappropriation of trade secrets. Fraud typically relates to deceit or misrepresentation to gain an unfair advantage. Extortion involves coercing someone to give up property or money under threat and doesn't involve trade secrets specifically. Receiving stolen property pertains more to knowingly taking control of goods that were stolen, without addressing the unique context of trade secrets. Therefore, theft of trademarks is the most accurate identification of the crime described.
