It seems that a new wave of web mapping patent lawsuits was started a few months ago, this time around the concept of "store location mapping"... more about this here:

http://apb.directionsmag.com/entry/patent-infringement-alleged-in-new-law-suit-for-store-location-mapping/163840

While the claims described in the patent don't seem to match current/modern techniques used for store location mapping, there are apparently ~300 companies who have to defend themselves against it, so any information you might have, or examples of prior art could be useful to them.

A little while ago, we had started a Wiki page to compile information about another Web Mapping Patent, and I just reorganized it to handle this new one, a.k.a the "474" patent:

If anyone has useful information to help fight potential lawsuits against this patent, or examples of prior art, then please send it along, or add it directly to the wiki page above.
