I have a patent application filed for a provisional somewhere last year, say, on March 01 2016. This provisional application had an element A which when placed on one area of element B resulted in result C.
This year, before the end of 12 months, the inventor wants to file a non-provisional. However, this time his invention has multiple element A but placed on more than one area of element B using same mechanism but now resulting in results C, D, E.
The provisional never had a claim part but we were specific about one element A. Now I would like to extend it to elements A, B, C placed on multiple area of element B to result in C, D and E.
My questions are:
- Will new elements B,C be a dependent claim based on previous provisional application?
- If patent granted, when will life period of invention A start and when will life of invention B,C start?
Also, generally, when does the life of a utility patent (20 years) start? Is it from the 1st filing date (Provisional/PCT/equivalent foreign application in last 12 months) or fromthe 1st effective filing date (application with claims) or from the date of USPTO publishing the invention?
