The survey was conducted on 7822 patents published by the Japanese Patent Office from the end of 1993 to the end of November 2011. Patent Result uses the company's own indicators to conduct patent evaluations at two points in time, "Now" and "End of 2008." The results of the assessment show that Sharp ranked fifth in 2008 and is currently ranked first (lower).
