Hate to break the news, Walt, but it happens very, very often. Even
years ago, when I was doing some consulting work on a patent case and
read a couple of hundred antenna patents, there was a great deal of
pseudo- and voodoo-science in issued patents. These days, it's rampant.

My favorite example is US patent #6,025,810, "Hyper-Light-Speed
Antenna", but I'm sure even this is far from the most egregious.

application.

This doesn't happen too often, but it does happen. Unless the patent examiner is
extremely well versed in electromagnetic theory he could easily be persuaded
that the EH principle is valid, while it is not.
