What everyone knows as a "Radiant Cut", GIA calls "Cut Cornered Rectangular Modified Brilliant"
They won't call it a Radiant cut no matter who cut it.
IMO names like "Radiant' and "Asscher" have become generic- unlike Xerox- which still takes efforts to protect the name.
In the case of the Radiant Cut, after an initial legal battle, the inventor had no problem at all seeing the term become part of jewelry lingo.
In the case of Asscher Cut- I do believe that the Royal Asscher Company would like it if no one used that name- at least that was the case a few years back.
But that cat is out of the bag.
Just like many other aspects of diamond shopping, selecting a great vendor is key.
For example, someone specializing in "Square Emerald Cuts' or Asschers, is likely to have a better chance of providing a great stone.
Considering "norms" and standards used today, vendors using names like "Radiant" or "Asscher" is no cause for concern in and of itself.
