The interesting thing about them is they include the full schematics
Also the
firmware for the sequencer.
The descriptions have to be complete to describe the "embodiment" of the
invention, which is then claimed to be the embodied device completely
contained within the host computer. The claims have to be described
relative to some physical device, and for whatever reason they decide to
throw in the whole thing.
xx863 claims the enclosed device in the host. xx153 claims a bunch of
improvements.
When I get time, I'd like to look at some of the claims such as claiming
that the method of rotational sensing of sectors is their improvement is
not prior art in 1989 (methods 28, 29 page 43 of xx153. I have the
luxury of working with a patent attorney right now, so this might be a
good learning experience.
Thanks for posting these, Al.
