I have a patent application that was poorly written. There have been no office actions on the merits and the application has not published. I want to basically rewrite the app, or at least change it significantly (for instance, they discussed their invention in the background section). I was thinking I could let the original app. go abandoned and file a continuation before abandonment, however, my concern is that I want to rewrite a lot of the specification. Can I do that (rewrite a lot of the spec)? Is there a better way to do it that still keeps the filing date?
Or should I file a CIP and rewrite most of the spec?
