The USPTO has urged independent inventors to beware of commercial invention-promotion services. The patent office warns people to examine the disclosures that invention promoters are now required to give to potential clients. They include: How many inventions they have evaluated; How many of those inventions received positive or negative evaluations; The total number of customers; How many of those customers received a net profit from the promoter's services; and How many of those customers have licensed their inventions because of the promoter's services. The Wichita Eagle, Eric Heels and Nipper have the story.
