Each day I am getting closer to taking a prototype I have been working on to market. Before it goes public, I would file for a provisional utility patent to determine if it is even a viable product, but I have a few questions before going further with it.
1) Right now, the prototype is about to enter its beta stage and I don't expect any of the ornamental appearances to change, but their may be slight adjustments along the way. Do design patents allow for minute adjustments to the final appearance, such as rounding a corner or moving a detail half a millimeter to the left ect... If not, then would it be better to wait until the very last minute before making the product public?
2) If said product is successful, their will be other versions, but will require very small changes to the outward appearance, will each of these iterations require new design patents?
Possible Duplicate Edit:
My future changes are not something that is interchangeable on the same product as the plug is that is described in the possible duplicate question. Each iteration of my product will be for a different "plug" per say, but it will be a completely separate product.
Also, if you read the first sentence provided "A broken line disclosure is understood to be for illustrative purposes only and forms no part of the claimed design." That does not protect the differences, it almost makes it sound arbitrary to even use dashed/broken lines.
I guess that main question would be, can a design patent cover a product line that are all visually similar, or does each product in the line need a design patent.
