在OECD ilibrary进去查找的数据,通过theme 进去选择Science and Technology,然后选择Databases下面的OECD Patent Statistics,进入后选择Patents by main technology and by International Patent Classification (IPC)下载的专利数据。 本人第一次用OECD数据库,想问一下大神们知道下载的是根据IPC分类号,有关技术创新的专利数据吗?数据后面带小数点,我找不到数据的单位,想问一下下载过该数据,或者懂的人能告诉我一下吗?这个数据单位是什么?
More than 100 countries worldwide are covered. Geographical aggregates are provided for the EU-28, the OECD total, and the World total.
Fractional counts applied for patents with multiple inventors/applicants:
When a patent was invented by several inventors from different countries, the respective contributions of each country is taken into account. This is done in order to eliminate multiple counting of such patents.
For example, a patent co-invented by 1 French, 1 American and 2 German residents will be counted as:
1/4th of a patent for France;
1/4th for the USA;
and ½ patent for Germany.
