Estoppel Scanner Beta

Enter a U.S. application number. Every place in the file wrapper where scope may have been given up: amendments after rejection, after-final responses, RCEs and terminal disclaimers, each pointing at the papers to read. Patent and publication numbers also work.

This is a beta and it is not legal advice. The scanner reads USPTO's document listing, never the documents themselves: it flags where to read, and whether scope was actually surrendered is a judgment that requires reading the papers.
