I'm thinking of using the following scheme for label-numbering the elements of patent drawings. Is there any reason it can't be used?
Each element has its "home-drawing" where it is presented with the best most detailed view of it. This "home-figure" is given the number N. In this home-drawing the element is given as label N.M where N is the number of the figure and N is an integer starting from 1 in each figure. So figure 1 might have elements 1.1, 1.2, 1.3 etc.
But some elements in a diagram "refer" to elements which are described in more detail in other drawings. Such a reference is given the same number as in its "home drawing" followed by one or more primes (') to indicate it is a reference and more detail about that element can be found by finding the element without the prime(s) in its label in some other diagram.
Thus every element across all drawings has a unique label-number but at the same time primed labels indicate that the same element is described with additional detail elsewhere, and is easy to find simply by looking up the figure that is the integer-part of the element.
Would this be an acceptable labeling scheme?
