Trend and Sale of Computer & Communication Patents in the United States

Pratheeba Vimalnath and Anjula Gurtoo
Abstract— The paper presents the growth of Computer & Communication (C&C) technologies in the past decade, 2005 –2014, using patent data in the matured United States (US) market and investigates the association between growth and the sale of patents in different C&C patent classes. The results demonstrate a striking 978.29% and 487.65% growth in information security (US class 726) and financial data processing (class 705) areas over the past decade, both belonging to the computer hardware and software category. Mapping of trend with sold US patents during 2006-2008, does not show more sales in the growing patent classes and not all classes sold more demonstrate higher growth. The pulse or digital communication space (class 375) for instance is the highest sold patent class but has relatively lesser growth in the past decade. The information storage component represented by class G9B, show lesser growth as well as lesser sale, indicating the death phase of the technology component. The implications and reasons for the results observed are discussed.

Index Terms— Computer & Communication, patent class, patent sale, technology growth.
