Jeeze, Brooke, I wish you hadn't brought up the possible patenting of Time
Delay Beam steering antennas! I wonder if my highly esteemed SDR radio
which I think uses some such technology, is illegal?

Hi:
When I was in high school I built an oscilloscope from a kit made by
Electronic Instrument Co. (EICO).
AFAICR Dumont had some patent that the kit avoided.
ARAIK you can build any patented device for you own use.
The reason I like patents is that they explain many things that books
avoid.
Time delay beam steering antennas (frequency independent unlike phased
array antennas) (Fenwick) are patented but even today not in antenna
books.
If you want to know what makes something a geodesic dome read the patent.
I have a tall stack of books and none of them spell it out.
Have Fun,
Brooke Clarke

Keep in mind that the patent(s) do not keep you from building a part for
your own use.
AS I understand it, this is not technically true. You can practice the
patent to gain an understanding of it for the purposes of inventing
something new that is based on that patent, or to design around it. But
you can't practice it, just because it's useful.
If I patent, oh, let's say, a swing consisting of a board (of an exotic,
but readily available, composite material) hanging from a tree limb with
two rods (of another exotic, but readily available material), you cannot
go out and build that swing in your backyard for your kids to play on.
You can, however, build that swing and do testing on it, connecting load
cells, motion tracking systems using real time kinematic GPS receivers,
and carefully measure the variations in the period of the swing as the
gravitational pull of the moon shifts, etc. Perhaps you are going to
build a better swing, maybe using 3 ropes instead of 2 (since my patent
attorney didn't write the claims well).
Regardless of what they do / do not patent, a TimeNut can still build
(and use for themselves) what ever they wish.

Now, if you (after careful examination) believe that the privately held
patents keep you from building a receiver for a Federally Funded
service - talk to your elected representatives. They are the ones who
can / will fire up a committee to look into this sort of stuff. I think
I would want to have some information on license costs before I made
that phone call though.
precisely so
Jim
