Been wondering about the trademark, there are a lot of variants with names also ending in -le (eg Nerdle, Semantle), would they be in any danger of getting a cease and desist? Asking for a friend ;)

I'm asking about the name because you can't patent gameplay afaik, so even if it was a straight clone, as long as the word list (and code?) was original it would be OK.

On the other hand I recall Worlds.com suing (somewhat successfully?) both Second Life and Minecraft, so maybe you can patent game concepts?
