Companies and Products

Based on public comments submitted to the USPTO, the agency compiled a list of more than 100 companies that have developed, are proposing to develop, or offering technological protection systems (including components thereof) to protect digitized copyrighted works and prevent infringement. A complete list of these companies is attached as Appendix A to this report. Many companies are constantly entering (and leaving) the rapidly evolving market for technological protection systems. Thus, as Congress itself recognized, any attempt to report on developments in this changing arena will “only provide a snapshot in time” because of the continual advances in technology.

Solely to provide information requested by Congress, this section of the report briefly discusses selected technological protection systems that are under development or currently available in the marketplace. All descriptions of commercially available products in this section are distilled from information that is made publicly available by the companies. The USPTO has not conducted an independent analysis of these products and services and makes no recommendations, comparisons, or comparative assessments of the technological protection systems discussed in this section or included in the list attached to this report as Appendix A. Almost all the products and services discussed in this section are registered trademarks.
