Samsung, LG and Sony are the most active in this research technology. Many color LCD televisions and monitors use this technology. Figure 17: Patent Time Distribution for Thin Film Transistors Patents Related to Digital Light Processing Figure 18 shows patent activity for digital light processing (DLP). DLP is used in many commercial theaters and has had fairly low but consistent patent activity over the studied period.

Mobile devices seem to have the most patent activity in the 2000-2012 period, with Motorola, LG, Sony, Panasonic and Samsung having large numbers of patents. Contrasting patents related to mobile devices with those related to tablets shows a remarkably different distribution. Patents for tables span the entire time spectrum, with a larger variety of participants indicated. Figure 19: Patent Time Distribution for Tablets 10

Summary This paper assessed the vast U.S. Patent Office information repository and an analytical methodology that extracts patent information and produces interesting insights to research development testing & evaluation (RDT&E) trends for several major technology companies. This research revealed interesting technology associations using SAS Enterprise Mine and Text Miner and expanded the utility of data mining by exposing unknown relationships and by assessing their prevalence in granted patents. Ultimately, this research helped uncover interesting RDT&E investment trends in two major thrusts. The methodology can be quickly adapted to other technology areas of interest across all industries.
