Grrrr.  Read the patent abstracts for the patent numbers cited in the
suit.  Essentially, Microchip patented the concept of an n-bit
microcontroller with n or fewer I/O pins.

Which leaves me wondering about 8-pin Atmel parts.  6 I/O pins...
have they had a suit there, too?

They filed patent suit against Zilog sometime ago for the low pin
count Z8.

Maybe Atmel already paid some money to Microchip. ;-)

I am not so sure about FreeScale which has the 8-pin MCU as well
(HC908QT series). Maybe they also paid. ;-)

Hmm, same three patents as they have thrown against Zilog. Haven't tried
looking, but wonder what is in them, especially as the court in the Zilog
case has caused the Patent Office to go back and re-asses them.

Bad article. It reproduces a lot of Cortex sales talk, but it does not
mention at all what the alledgely infringed patents are about!

I checked the three uChip 'patents'. They are all about having more
(selecteable) pin functions than pins (a form of multiplexing) I am not
against patents, but reading these three ones I hope the defendant will
find the propper prior art, and Microchip will be found guilty of utter
contempt of court!
