Plausibility & Inventive Step - Complex Issues Simplified for IP Lawyers & Patent Attorneys

Introduction

In addition to the 'classic' approach to determining inventive step, which asks whether the invention was obvious to a person skilled in the art, a threshold step of 'plausibility' has emerged from EPO case law.

First introduced into UK patent law over a decade ago, plausibility has been applied in a number of inventive step cases and is now an important and unavoidable issue.

This webinar will explain plausibility and bring you up to date on what we know about its application in the inventive step context.
