Has the "dynohub" trademark fallen out of disuse? (bicycle semantics)
"Dynohub" originates as a Sturmey Archer trademark for their original dynamo hub. I understand that the current SA is owned by Sun Race, and is not the same company.
I have noticed that the current SA refers to its offerings by the generic "dynamo hub".
Dynohub has a nice ring to it, but I try to use it only to refer to English made SA out of respect. Now that SA is no longer English, the new SA seems to no longer use the trademark "Dynohub". I generally refer to other hubs as dynamo hubs, which doesn't quite roll off the tongue as well as dynohub.
Did the trademark go to Sun Race, or does some other entity currently own it? Or has it become diluted like Xerox or Kleenex?
Personally, aside from Dynohub, I'd like "magnetohub" to be the common term. Historically, within electrical engineering, a dynamo produces DC current, whereas a magneto is a permanent magnet alternator.
I'm just curious if anyone knows the current status of the trademark "dynohub"?
I know, bicycle minutia...
