can do anything to stop you discussing how to avoid their patent.
Nothing to stop them trying to scare you off though.
I was actually doing more than just discussing it, I had been
doing it in my basement for a couple of years and even was selling
my product. My mistake was discussing it on Usenet.
"It" in this case is PWM modulation of R, G, and B LED's which
are then mixed together. And that is exactly what their
patent covers, even though it was blatantly obvious long
before they ever existed.
