I think Rick misspoke. The patent of his I linked, is
not a design patent, but a utility patent. (A design patent wouldn't protect his invention in any meaningful way. The utility patent does. I've seen his original stabilizer patent, but don't recall which type it was. If it's not a utility patent, he should sue his patent lawyer!

)
It doesn't matter at all if the Roboblock does the same thing, but "differently". What matters are Rick's claims (enunciated in his patent that I linked) and whether or not the Roboblock will fulfill or "read on" to all the stipulations in at least one of Rick's claims. (It does not matter if the Roboblock does more than what is described in the patent, or if there are technical differences. All that matters is whether it
at least meets the limitations described in any one of Rick's claims.) If the Roboblock does not embody all the limitations of at least one of Rick's claims, they owe him nothing.
If it does, then it is infringing.
If there is infringement, one of four things usually happens. One is, the infringer drops the project. Two, and infringer comes to an agreement with the patent holder and is granted lisense to produce the technology. Another common response, is that an infringer goes ahead and makes the 100 knives or so and presumes the patent holder either won't find out, or wish to litigate for tens of thousands of dollars over such a small number of knives. Yet another common response is the designer of the infringing item studies the troublesome patent and adjusts his design until it no longer "reads on" to at least one of the claims.
There is another very common approach being used today thanks to the 2007 Supreme Court KSR vs. Teleflex decision, but I don't think that would be applicable in this case.
If Rick does not have a patent in Italy, they are legally free to make and sell the item there and anywhere else, for that matter,
other than the US.
The smart play, I think would be for the Italian firm to work with Rick on this. It will make everyone happy and probably increase sales though an official association with Hinderer.:thumbup:
