While certainly candid, I think that these examples fall down flat as they don't stimulate discussion. I think if you want to be memorable, just write a short section called "Ask Me About" at the end of your (1 sided!) resume. For example, 1. I submitted a patent application for a consumer electronics product that was rejected. or 2. I am very curious about new webapps and keenly participate in beta programmes. Either of these are very easy for an interviewer to ask about and I find much more useful than "President of University Chess Society" type info.
