Just a brief warning. I recieved an email from this American company asking me for an idea I'd like to invent. I sent a reply, now they are asking me for money. Obviuosly I researched this company to see if was worth doing, and I found the US patentsoffice and there are about twenty complaints, maybe more about this company. They sound like a good company but just be careful. Whenever anyone asks for money on the net always research the company, to see if there's been any complaints. I think they've burnt their brodges in America so there trying their luck over here
