This study aimed at analyzing the impact and
importance of power and electronics patents in technology
development. Citation analysis was used as the research method,
using the especial formulas of the forward-looking and backwardlooking
measures. The research population includes all patents in the
field of power and electronics recorded from 1987 to 2006 in the
USPTO.
Analyzing the importance of patents in knowledge flow and their
past and future effect on technology development indicated that at
least 10 years should be passed from their release in order to their real
effect on technology be seen. The mean of generality grade to
determine the effect and application of patents in different subject
areas showed that in addition to patents’ effect in electronics field,
they have a high tendency to have relations with other subject areas. It
was also found that there existed a significant relation between
forward and backward looking measures, showing the dependence of
future effect of a patent to its backward citations.
