Nothing I have seen sounds right for my little invention, so I wonder what I'm missing. The invention needs at least one X somewhere on at least the first side of Y for the minimum invention to work. In the preferred embodiments, one or more additional X at particular locations and/or slope directions on Y adds value and narrows the claim. So the dependent claims need to say: at least one X on the second side of Y. at least one X proximal to the distal end of Y. at least one X proximal to the proximal end of Y. at least one X to slope left. at least one X to slope right. What is a good way to say this?
You could draft it like this:
Device comprising: at least one X, the at least one X comprising a first X at location A.
Device according to claim 1, wherein the at least one X further comprises a second X at location B.
Device according to claim 1, wherein the at least one X further comprises a second X at location C.
