Davison Design and Development Inc, aka Davison Associates, aka Davison Inventagration is a high-profile invention promotion company that has been featured on NBC, CBS, in a number of magazines, and on Ripley's Believe It or Not, mostly because of their truly innovative factory, called InventLand. They also advertise very heavily on the net and convenionally. They seem to be a model company. However, they have a very dark side.
Go to the Federal Trade Commission (FTC) website, and search "Inventors". The first topic is "FTC News results for Inventors".
Click on "Invention Promoters Will Pay $10 Million to Settle FTC Charges", and read the article dated July 18, 2009. Davison was sued because their "development" charges far exceeded the returns for most of the clients who trusted them. In fact, after the settlement, most of these people will still not receive what they lost to Davison.
The article on the FTC web site also stipulates information Davison must post on all correspondence and web sites. Davison does supply it in correspondence, but it is not on the web site. Further, Davison shows 94 products they claim are receiving royalties for their inventors. If you investigate each product, you will see that most are developed by and licensed to Davison Design. The ones developed by individual investors are a distinct minority, and half of those have received no net profit. Since Davison claims to receive hundreds of submissions, one must ask what has become of all those other submissions, who are paying $15, 000 and more for Davison's "help".
