In the final month of 2018, Unified filed an unprecedented 23 new inter partes review challenges — each of which challenges a different NPE-controlled patent — setting a new record for the most petitions filed by a company in a single month against NPEs since the PTAB’s inception. Simultaneously, Unified set the record for most unique patent challenges against NPEs filed on a single day (12) on December 31.
These challenges were spread out against an assortment of patents owned and asserted by well-known NPEs such as Dominion Harbor, Uniloc, Sisvel, IP Valuation Partners, QuarterHill, and Brad Liddle, among others.

Patent litigation in 2018 decreased by 5% overall compared to 2017 due to a drop in the number of new filings at both the district court and Patent Trial and Appeal Board (PTAB). However, this decrease is proportionally smaller compared to previous years which may indicate that the volume of new patent disputes is leveling out. Despite the general downward trend in 2018, the number of patent disputes involving Medical companies increased for the first time since 2015.
Highlights:
District Courts and PTAB disputes decreased by 5% overall.
