Finnegan’s Advanced Technology Patent Report 2015 is a comprehensive guide to significant developments in U.S. patent law and practice for the electrical and computer technology fields. It covers three main areas: patent prosecution, post-grant proceedings, and litigation. The report distills key precedents from the Supreme Court and Federal Circuit, and explains how they are driving changes at all levels of practice. Complementing its review of patent law developments, the report includes a collection of useful statistics, including those related to patent filings, grants by technology class, and district court litigation. Some unique Patent Trial and Appeal Board (PTAB) statistics are also provided, including a breakdown on evidentiary sources relied on for claim construction.
