[aprssig] Re: Kenwood Status - Thinking about TH-D7AG purchase

Technically they could implement the algorithm (or something very 
similar) and just call it something different, since the trademark only 
covers the name.  A utility patent would cover the algorithm itself - 
just like the APRS trademark covers the name (and the dosaprs software 
and protocol spec document are protected by copyright) but not the system.

I chose to use the SmartBeaconing mark with my products to give credit 
to the creators, and because there's value in letting the users know 
that it's the same thing as in other products.  Kenwood might not make 
the same decision.
