Susan…that is a strange one…that they have an idea close to yours patented. The question is how close. You say it does the same thing but then yours solves another problem. A little unclear of your situation to judge.
I would tell them you plan on filing other patents or a CIP to “broaden your protection” You are obligated to show them your existing claims when you are close to a deal but I would try and keep “your hand” quiet as long as you can.
See, the problem with going to a company that has like products is sometimes the inventor can only hurt them. Sometimes though they will license or even buy your patent so you can’t hurt them. They pay you off and you go away. Or sign a license agreement and just sit on it…waste your time.
Ask yourself this with inventing. Do they really need to let you in on a partnership and pay you royalties? Does it make sense when they add up their gross income?
Many inventors make the GIANT mistake of going to the industry leader who is ALREADY the leader of the market share. What do they need you for???? They don’t care if your idea is better if they already are making tons of money and leading the market. Why would they need to all of a sudden let you in and give you 5% royalties which comes out to about 20% of the profit on the manufactured product (average)
So Susan, ask yourself, do they need your product or are they now going to play games with you. I don’t like how they say they have something very very similar.
As far as the lawyers in your face now in the top seat in your deal…I know …I hate that…but that is the way it is with bigger companies. It takes the enthusiasm and the smiles and handshakes right out of the project sometimes, but big companies MUST do that…they have too much at risk to make an incomplete deal that will cause problems later.
You could PM me if you want to give me private information so I can give you an opinion…but you are doing well…you know what you are doing.
It gets tricky…this is why most licensing deals get wrecked when the inventor tries to tackle themselves. The deals last a little while and then the whole project gets a mess after a few years and the inventor gets ripped off or a great product is laid to rest….that is why I am a fan of letting Edison Nation handle all….let them have the headaches…they asked for it….and they split the profit with you…..all for no money down.
