LITIGATION ANALYSIS OF ETSI DECLARED PATENTS
This report aims to understand the litigation landscape of ETSI-declared patents litigated in the US. It analyzes the yearly trend of litigation cases, and the number of declared patents involved.
The types of plaintiffs were analyzed to understand the share of practicing entities (PES) and non- practicing entities (NPEs) in litigation cases.
The analysis also seeks to understand the history of litigated patents, top 10 NPES and PEs, including which declarants or assignees reassign their declared patents to PES and NPEs.
Moreover, the analysis also aims to understand how many IPR cases were filed against the litigated patents and the outcome of the IPR case history.
This report comprehensively analyzes litigated patents declared to ETSI, highlighting key trends in litigation history and plaintiff analysis, focusing on the roles of NPES, reassignment patterns, and IPR case outcomes. It has been found that a significant number of asserted patents,443 unique families, were litigated after the declaration.
In contrast, a smaller fraction, XX families, were declared post-litigation, and XX asserted patents were not declared per se, but their family members were declared to ETSI. Reassignment of patents before and after litigation was observed, with some entities transferring ownership strategically.
A significant number of litigation cases were filed by NPES. Of the XXX patents, XX percent were reassigned to NPES, highlighting the interest of NPEs in ETSI-declared assets.
The patent litigation dataset was prepared using USPTO and Unified patent database data, whereas ETSI declaration data was accessed from ETSI. Information from Patent litigation data was compared with the declared patent families to understand how many declared patents were litigated in the US.
Following a comprehensive analysis, 500 patents declared in the ETSI declaration database were found to have been litigated.
