When TiVo applied for this patent, something
like 16 years ago, it was not obvious that you
could build a _digital_ tv recorder using disk
drive technology. I proposed a digital TV set
in the mid-1980s, and all during that time none
of the people I talked to suggested building a
TiVo kind of device. So, no, the original
patent does not fail the "obviousness test".
After ten years of TiVo being widely available,
and with today's college students not being
able to remember a time before TiVo was out,
there is a danger of applying today's standards
of obviousness to the early 1990's.
It looks to me like EchoStar are just a bunch
of ripoffs. They blatantly copied TiVo's stuff
and more-or-less challenged them to sue, and
then used their ill-gotten gains to hire a
bunch of lawyers and PR types to stop TiVo
from getting justice. Oh, yeah, they almost
put TiVo out of business with their low-cost
competition. (Nothing like stealing your tech
to cut your costs: R&D is expensive. . .)
