Christopher -

TopoZone used a "web interface for batches of tiles" starting in 1999,
and it was not novel then, as it was very similar to the mechanism
Microsoft used in TerraServer in 1998.  TopoZone continued to use that
interface until 2003 when we switched to a MapServer-based
whole-map-in-one-custom-image approach.  We were happy to move away from
what we thought was an "antiquated" way of doing things!

I'm not aware of any web interface which sent requests for batches of
tiles before Google Maps. The ones I'm aware of now are:
 * OpenLayers, originally started working on around Where 2.0 1
 * ka-Map, started around the same time -- after February 2005 (patent)
 * MapGuide, I think, which has tile batch requests
 * I've heard info about ESRI's new stuff doing the same thing.

So, as far as the first claim of the patent that Google was granted 
("Digital Mapping Service" or whatever), I'm not aware of anything that
predates their patent application in Feb 2005. I certainly know that it
seemed novel to everyone when it came out.
