1) His website says his patents are owned by Lodsys and Webventions. I did not see anything that said he runs those companies. What I find by Googling is that one or both of these companies may be owned by Intellectual Ventures, or if not owned by IV, they likely acquired their Abelow patents from IV. Abelow seems to be at least two steps removed from both companies.

2) I see nothing in those Google searches that shows a history of patent trolling, unless you are using a very broad definition of patent trolling (one so broad as to be close to meaningless).
