I guess I'm the unfriendly one.  That's what I get for being in criminal instead of patent law.

My woefully inadequate understanding is, though, that the US patent system doesn't allow external input in the patent examination process other than for a two month period after the patent is published.  It was published in April according to USPTO so that time period has expired.

The claims are very specific, though, and my understanding (again, woefully inadequate) is that the claims control what can be asserted, not the abstract.  The claims talk about a backplane with multiple "cores" on board, a power supply and even clocks.  This wouldn't necessarily apply to OpenHPSDR.  The patent, overall, doesn't seem particularly novel though.

This is just above Phil Karn's cat exerciser patent (waving a laser pointer on the floor in front of a cat).  He is from Germantown Maryland. It was filed in April.
