Yea, I see that on their data sheet. I looked on the USPTO site under everything that I could think of and found nothing by Eighteen sound let alone a phase plug.

Maybe it's because they're an Italian company - maybe it's an Italian patent or is there European Union patent organization?

Definitely an 18 Sound patent for a phase plug - can't say if it's the right one.
