***** To join INSNA, visit http://www.insna.org ***** Dear colleagues, In collaboration with others, I now made more systematically routines available at http://www.leydesdorff.net/software/uspatents that allow in addition to geographical mapping <http://www.leydesdorff.net/software/patentmaps/index.htm> and mapping in terms of Intern. Patent Classifications <http://www.leydesdorff.net/ipcmaps> to download the cited and citing patents in the USPTO domain (that is, since 1975). Please, feel free to feedback with suggestions for improvements. Best wishes, Loet _____ Loet Leydesdorff Professor, University of Amsterdam Amsterdam School of Communications Research (ASCoR) Kloveniersburgwal 48, 1012 CX Amsterdam <mailto:[log in to unmask]> [log in to unmask] ; <http://www.leydesdorff.net/> http://www.leydesdorff.net/ Honorary Professor, SPRU, <http://www.sussex.ac.uk/spru/> University of Sussex; Visiting Professor, ISTIC, <http://www.istic.ac.cn/Eng/brief_en.html> Beijing; http://scholar.google.com/citations?user=ych9gNYAAAAJ <http://scholar.google.com/citations?user=ych9gNYAAAAJ&hl=en> &hl=en _____________________________________________________________________ SOCNET is a service of INSNA, the professional association for social network researchers (http://www.insna.org).
