Searching Patents Protecting ITU Telecommunication Standards

ITU provides a tool to search for patents protecting each of the ITU standards based on declarations made by companies.

Link to the Database and Tool --> http://www.itu.int/ipr/IPRSearch.aspx?iprtype=PS


This tool is good to get patents covering each technology including the basic patents for each technology as per the telecom standard and also the competing companies.

However, this information and the relevancy of patents is not verified by ITU.
