Many Cards Versus One Card and a List Field

[Mikey]

Richard,
Obviously others have commented on the patent.  If the patent hasn't
expired, it is about to, and the technique will be described in the
patent application.

Regardless, there is nothing that stops anyone from circumventing a
patent by reverse-engineering it, which is generally the favored
technique.

Finally, the argument that "everyone else is doing" something would
have led to HC never being created in the first place.  Paradigms are
made to be broken.
