Examiner Interviews by Video

by Ed Ryan
The Examiner interview is the cornerstone of effective patent prosecution. A short conversation can advance prosecution more effectively than reams of written response.

The Claim Contingency: How If-Then Language Can Sink a Patent

Edward Ryan Conditional language seems like a natural choice for describing computer-based inventions. The if-then structure mimics computer logic, allowing an algorithm to be translated directly into the claims. But, thanks to a counter-intuitive and inconsistently applied principle of claim interpretation, using this language can result in claim elements being ignored entirely--both in prosecution and in litigation. How are conditional claim limitations...

Avoiding a First-Action Final Office Action – May 14, 2018

By Ed Ryan There is a natural rhythm to patent prosecution, from non-final, to amendment, to final, to RCE, but that rhythm can be disrupted by an aggressive patent examiner. While the patent practitioner generally expects a new non-final Office Action after filing an RCE or continuing application, a first-action Final Office Action can sometimes result. This cuts off many of...
