The idea of patents is to encourage inventions by allowing the inventor
sole rights to a new idea for a limited time, provided he publishes the
idea, so (a) everybody can use it now if they pay the inventor, and (b)
everybody can use it later, and can build on it.

The best patents are always sweeping ideas with many applications. If
yoiu can't come up with any such, you may be able to invent process
improvements or applications.

Really! Soderblom patented a unidirectional digital repeater/transceiver
and nowhere mentioned repeater.  That is real clarity.  Now it is
possible that the complete patent mentions that the circuit is a digital
repeater, but I doubt it for the very good reason that the concept of a
digital repeater is not patentable in 1967.

No, it covers a much larger class of digital repeaters against
which Soderblom is making no claims because the bogosity of
this patent would be obvious.

Wrongo! You can patent non-obvious extensions to existing ideas.  In
1890 the concept of cooking with heat was well-known and the concept of
generating heat via electricity was well-known.  The concept of cooking
with electrically-generated heat would have been practically
self-evident to any engineer working in the field especially since
chemists were already using electrically generated heat to stimulate
chemical reactions (sounds like cooking to me) at this time period.

But that is it exactly.  There is nothing at all new in a slightly
intelligent unidirectional digital repeater in 1967.  Giving a old
device a new name to obscure what it really is does not a new idea make. 
There may be something new and clever in the specific circuit Soderblom
invented, and I have no problem with the Soderblom patent covering
the specific circuit.

Yes, the digital repeater in the 1950's was a sweeping idea with many
applications, but Soderblom did not invent it.
