Animations of the geographical dynamics of patents (from PatStat or USPTO) using PatViz
PatViz enables the user to animate output from the (geo-coded) patent maps produced from USPTO data (at http://www.leydesdorff.net/software/patentmaps/dynamic ) or from PatStat data (at http://www.leydesdorff.net/software/patstat) directly both locally and at the internet. (An interactive version is also provided at http://semweb.cs.vu.nl/patents2 or http://www.leydesdorff.net/patviz.)
The last release can be downloaded from https://github.com/Data2Semantics/PatViz/releases for local installation. After unzipping the file, one installs the program and can run it on one’s computer by clicking on index.html. (The computer needs to be connected in order to download the Google Maps providing the background.) The resulting files can also be uploaded after replacing the API key of Google Maps with the one for one’s own machine.
The routine is part of the project
Loet Leydesdorff, Floortje Alkemade, Gaston Heimeriks, and Rinke Hoekstra (in preparation), Geographic and Technological Perspectives on “Photovoltaic Cells:” Patents as Instruments for Exploring Innovation Dynamics.
Currently, the program can select and read files with the extensions pat*.txt (e.g., pat1980.txt, pat1981.txt, etc.) as generated by ps_ipcyr.exe for PatStat data; and the files z*.txt generated by usptoyr.exe for USPTO data. Instructions for preparing this data can be found at http://www.leydesdorff.net/software/patstat and http://www.leydesdorff.net/software/patentmaps/dynamic , respectively. Instead of visualizing these files one-by-one and then generate maps for each year, the program PatViz allows to submit a time series of files; the program then generates the animation using the parameters specified in the paper. The program provides two demos using data for CuInSe2 as material technology for PV cells using Y02E10/541 as the Cooperative Patent Classification for the download in USPTO and PatStat, respectively.
