I'm genuinely interested, are you talking about Onyxboox Mira or Dasung ? Because i thought that they manufactured official e-ink patented products

I was talking about Dasung. Dasung respect the patents? My bad then, I've read somewhere they were not.

Dasung panels are properly licensed from eInk Corp. They (Dasung) actually have a couple patents of their own on their e-ink driver board tech, which drives the panels. If you're searching a patent database, search for "Beijing Dasung".
