Valtrus Innovations Limited, backed by Irish patent monetization platform Key Patent Innovations, has rapidly developed multiple parallel assertion programs built on large tranches of acquired assets, targeting cloud, data center, storage, and open‑source‑related technology.
The Valtrus campaign is supported by a sophisticated financing structure and an experienced assertion team. It has already generated a dense landscape of district court litigation, IPRs, declaratory judgement and reexamination activity that Unified has analyzed to better inform its members on strategy for dealing with the infringement and licensing demands Valtrus and its affiliates are currently asserting.
In this members-only confidential summary, a draft example of Unified’s invalidity and ex parte reexamination work product for one of the Valtrus patents is included in the report.
