Where are you located? You can give my patent atty (and friend) a call, I've used him for 10+ years and done at least 10 applications with him. His name is David Powsner with Nutter, McCellan in Boston.(http://www.nutter.com/attorneys.php?AttorneyID=110). Great guy, friendly and very knowledgeable. If you do email him, tell him chandra referred you.
