i filed a provisionalm patent application for a children`s camping product i designed . i have used the time and the "patent pending" protection to show my product to manufactureres with some great response. i even found a reliable manufacturer who has created five factory prototypes at their expense and would like me to make some serious sales contacts.the problem is that in three months my provisional application will be up and i need more time to show and develop buisness contacts before deciding to invest the heavy money in a utility patent or not. is their a way to extend the protection of the provisional application or something similar both in the u.s and european union?
appreciate any solid advice
