Description
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. Reassignment of patents before and after litigation was observed, with some entities transferring ownership strategically.
Information from Patent litigation data was compared with the declared patent families to understand how many declared patents were litigated in the US. Therefore, 576 declared patent families involved in 264 litigation cases were included in the analysis.
Frequently asked questions
What does the litigation analysis of ETSI patents examine?
The report examines the litigation landscape of ETSI declared patents that have been litigated in the US. It analyses the yearly trend of litigation cases and the number of declared patents involved, the history of the litigated patents, and how many IPR cases were filed against them and with what outcome. Reassignment of patents before and after litigation is also examined, since some entities transfer ownership strategically.
How were the cases and patents selected?
Patent litigation data was compared with the declared patent families to establish how many declared patents had been litigated in the US. On that basis, 576 declared patent families involved in 264 litigation cases were included in the analysis. The study found that a significant number of asserted patents, 443 unique families, were litigated after the declaration was made to the standards body.
Does the report separate practising and non-practising entities?
Yes. Plaintiff types were analysed to show the share of practising entities and non-practising entities in the litigation cases. The report identifies the top ten in each group and looks at which declarants or assignees reassign their declared patents to them. That view helps a reader see how declared portfolios change hands and who tends to assert them once ownership has moved.
Who would find this litigation analysis useful?
Licensing teams, in house counsel and standards participants who deal with declared patents will find it useful. It supports risk assessment by showing which declared families have been asserted, how often an IPR followed, and how ownership shifted around litigation. The report is provided on request through the contact page, and the scope can be adjusted to particular declarants, case years or technology areas.
