Referring to this question:
Adding useful and unobvious functionality to existing patent
Alice has thus decided to proceed with filing a Continuation-In-Part application. Would it suffice a simple drafting format, whereby, after referring to the parent patent, only the new functionality is described ? without needing to repeat the full content of the parent patent? Such as for example:
CROSS-REFERENCE TO RELATED PATENTS
This U.S. patent application is a Continuation-In-Part of U.S. Patent XYZ which was granted on ....
FIELD OF THE INVENTION
The present disclosure relates to a blood pressure measurement method and apparatus, whereby the diagnostic functionality consisting of .......... is added to the Parent Patent XYZ by monitoring the signal W (shown at least in Fig. m and Fig. n of patent XYZ). The advantages obtained are ......... etc. etc.
To then formulate the claims as explicitly dependent from those in patent XYZ. Such as for example:
1. The method of Claim 1 of the parent patent XYZ, further comprising the step of .... etc. etc.
2. An apparatus configured to implement the method as claimed in claim 1 of this application, wherein .... etc. etc.
It would appear to me that such an approach would make it easier for everybody to identify and isolate the delta novelty with respect to the parent patent. However, I know there must be some formalities to be respected. Unfortunately, I have not been able to locate, on the USPTO website, published examples for what would be considered acceptable formats for Continuation-In-Part Specification and Claims. I did read few published Continuation-In-Part applications, but all seem to fully rewrite Specification and Claims, mostly fully rewording the Claims, and thus requiring, at least to my unexpert eyes (I am not an examiner), quite some effort to isolate the improvement part.
By the way, would Claim 1 above be considered a dependent claim (being dependent on Claim 1 of the Parent Patent)? and would Claim 2 thus be considered a multi-dependent claim (depending on Claim 1, in turn depending on Claim 1 of the Parent Patent)? I am thinking about how to correctly calculate filing fees ...
