The chart plots for each year the number of patent families of Italian research institutes from the first publication available in the entire time series. By manipulating the slider below the chart, you can control the number of institutes displayed and the time interval considered (for each institution and each family is considered the first date of publication in the documents that populate the patent family).
The query retrieves all patents filed in the time period considered, grouped by families and home institution (considering that a patent application may be filed by one or more institutes at the same time). The chart shows for each time interval the total number of inventions of Italian research institutes considering the date on which the patent document was made public.
