So the question begs, how come there was never any effort to patent the card?

I do not design cards but I do know many people who do.  The TDM400P
was a piece of junk and Digium very often blamed the motherboard for
the issues.  This was until Sangoma came on the scene and raised the
bar.  With ~15 employees no less.  People jumped ship from Digium in
droves (similar to lemmings) to go to Sangoma  since the IRQ issues
were null.  Competition is the only reason we have cards that are up
to par.

I think you are new to Digium but I have quite a bit of back ground
info dating back to Linux Support Services and the fact that the .3
version of Asterisk only supported Adtran (go figure...)

I can certainly post more "dirt" from Mark's previous right hand man
if you wish to continue this argument.

The truth will set you free.  Don't buy Digium propaganda, look at the facts.

Why would Mark build a PBX from scratch for his start-up when a
Toshiba, 3Com, or NEC could be had for a few hundred dollars (not to
mention Mark's close ties with Adtran including funding.  Things just
don't add up, let's use our brains and not by the zeitgeist put out by
Digium.
