Please answer these two questions:

1. What is wrong with revising a patent based on Patent Office feedback? "P.O.:This is objectionable for reasons x, y, z" , "Applicant: Ok, thanks, I'll change x, y, z so as not to be objectionable". This seems like a reasonable exchange on the face of it.

2. How will you distinguish 'revisions' from 'new' patents that are substantially similar to previous patent applications?

Remember that some companies (MSFT/Google/IBM) file for many, many patents every year.
