From what I understood once I have filled for a patent, I can't have a public campaign about the product as I have less chances for the patent to be accepted.
Check out the interview I did with the Founder of Huli Huli on CrowdfundBeat.com
Also, I'd look at the Sell Something function on CrowdTilt.com
FYI, we are launching a new Web TV Series about StartUps In Action on CrowdFundBeat, DailyMotion, CrowdSourcing,org, and more along with national broadcast AM radio.
