Supplementary notes

* A patent family is defined as a group of patent documents all of which have the same set of priorities. I.e., it is a group of patent documents that protect the same invention across authorities.

The owner of a patent includes all patents owned by a company and its subsidiaries (by at least 50%) based on comprehensive research on corporate structures, M&A, Spin-offs, company names changes, patent transactions. PatentSight also tracks former names of companies and subsidiaries, ongoing mergers and acquisitions, acquisitions of the past, reassignments, companies that have the same applicant, and transliterations by patent offices.

Technology field definition by Swiss Federal Institute of Intellectual Property – ip-search: "Data security refers to protective digital privacy measures that are applied to prevent unauthorized access to computers, databases and websites. Data security also protects data from corruption and is an essential aspect of IT for organizations of every size and type. Data security is also known as information security (IS) or computer security. The technology field covers therefore a broad view on authentication (of persons, devices, products) as well as various encryption technologies, used to protect hardware, network and communication environments as well as a technologies to insure consumer product originality."
