Not sure of a generic expression, but you could always use Counterfeit.
To counterfeit means to imitate something. Counterfeit products are
fake replicas of the real product. Counterfeit products are often
produced with the intent to take advantage of the superior value of
the imitated product. The word counterfeit frequently describes both
the forgeries of currency and documents, as well as the imitations of
clothing, handbags, shoes, pharmaceuticals, aviation and automobile
parts, watches, electronics (both parts and finished products),
software, works of art, toys, movies. Counterfeit products tend to
have fake company logos and brands. In the case of goods, it results
in patent infringement or trademark infringement. Counterfeit consumer
products have a reputation for being lower quality (sometimes not
working at all) and may even include toxic elements. This has resulted
in the deaths of hundreds of thousands of people, due to automobile
and aviation accidents, poisoning, ceasing to take essential compounds
(e.g. in the case a person takes non-working medicine, ...).
