I'd like to know whether there is a word limit for the patent description (summary and detailed summary)?
If not, is there an overall paper/word limit before fees accrue? That is, after how many patent pages will you be charged for going over?
The answer from the USPTO's current fee schedule:
Every piece of paper (or virtual page) is counted including the claims and abstract and drawings. If you give them a program listing or DNA sequence a CD those pages don't count.
