I am in the process of designing a mechanicle invention I am very close to being able to test but want some sort of legal protection before I go further. A provisional application seems to be the next step. Since I have a basic design but dont have all the kinks worked out when it comes time to file the non provisional patent there will be some changes or additions to the design. I am wondering how much I can change the design between the provisional application and the final application?
This is a question for a patent attorney. They are super-expensive for a reason. It is a rather specialized area of the law.
