Italian to English Law/Patents Law (general)

In a legal brief I came across this sentence:

"Il millantato contatto che A avrebbe procurato a B, dunque, non rappresentava per quest’ultima nessun valore aggiunto."

This sounds similar to "millantato credito" (which is a typical expression in Italian), though, as far as I know, is not widely used. The sense here is that the company A brags about the business contacts provided to B, although B claims that A's contribution was not really significant. Any idea of a possible English equivalent for "millantato contatto"? TIA
