The following chart shows the country of residence for the patentee of patents granted in 2009:
The chart shows a clear decline in granted patents from all major applicant countries, namely Germany, Japan and the US (the chart colours of Germany and the UK are almost undistinguishable, but a look in the corresponding table shows that Germany is the top line. Sorry, UK readers). All together, applicants from Germany, the U.S. and Japan received 61% of the patents granted in 2009. South Korea is the only one of the major filing nations that seems to (almost) hold its number of applications. The full chart is here, corresponding table here.
There is also a table on patent applications by technical field and country of origin. Unfortunately, like the rest of the statistics, it's a PDF, which makes the analysis very hard. May I suggest publishing such data as a spreadsheet in the future, allowing further processing?
