I performed a prior art search based on the Lodsys '078 Patent. I have not yet taken the time to determine if they should be granted the priority dates of all the continuations and CIP they filed, dating all the way back to Aug 6, 1992. If someone wants to help with that analysis, please have at it.
Thus, I performed a search of patents that were filed prior to Aug. 6, 1992, as it seems to be the earliest claim to priority for the '078 patent. Here is my first set of results and short summary of their subject area.

Definition - "Patent Troll"
"PATENT TROLL" - Any party that intentionally misconstrues the claims of their patent to assert it against another. A patent troll does not have to be a non-practicing entity (NPE) or in any particular industry, all that is required is an intentional misconstruing of the claims in an attempt to extort money from another.
