    That's curious, looks exactly like MLTLs as descibed by Ausgpurger 60 years ago. What's the novel improvement that warranted a patent?

    This looks like a port at the end of a transmission line… this post was dated 2013-03-13 diyAudio Forum

    Which makes this (I believe) public disclosure / public use

    Not like there’s a USPTO rule; 2001 Duty of Disclosure, Candor, and Good Faith [R-08.2017] or anything… Oh, snap.

    I’m sure it all passed muster as a novel improvement

    It's an MLTL, called something else. Marketing patent development.

    US Patents have been first to file since 2013. If the claimed invention was in the public domain before filing, then it shouldn't have been allowed and is not a valid patent. At this point, that would become an issue if the patent owner ever tried to enforce it.

    Keep an open mind, but don't let your brain fall out.

    You are correct. I should have stopped at prior art.
