3.2 PATENT ACTIVITY BY PATENT AUTHORITYThe previous section reviewed for the assistive devices and technologies for visually and hearing impaired persons technology collection at a regional level; this section drills into the activity at a national level. The analysis rests upon the same correlation between the office of first filing location and the geographic location of patent applicants. Figure 11 shows the major office of first filing (i.e. the priority filing) locations of applicants in the assistive devices and technologies for visually and hearing impaired persons technology landscape. The United States is the pre-eminent source of activity, making up a significantly large proportion of all activity. Japan is the secondary source of activity; however, as figure 11 (timeline of activity by major office of first filing location) shows, Japanese and United States activity is on the decline. Chinese activity has grown substantially. From 2004, Chinese patent activity has been continually increasing, eventually overtaking Japan in 2010 as the second highest source of activity. If its current trajectory continues, it will overtake the United States in the near future as the primary source of patent activity in this technology field. At the same time, Japanese activity has slumped. 2004 reveals a major drop in Japanese patent activity. 2008 shows patent activity for most top countries beginning to decrease at a steady rate apart from China who is increasing strongly.

Chinese activity continues to increase at this point however this positive activity from China has not been enough to counteract the overall downward trend caused by other countries. 
Figure 12 - Timeline of Patent Activity for Top 5 Office of First Filing Locations; Earliest First Filing Year; Excludes Incomplete Years The timeline in figure 12 is summarized in trend form in figure 13. This shows the compound annual growth or decline in patent activity between 2007 and 2011, and highlights growth for China, South Korea and the United Kingdom, as well as the stagnation and decline of activity from many other jurisdictions including Australia, Germany and the United States.
