Ibero-American patent information with Latipat: public search systems and their differences Jürgens, Björn Herrero Solana, Víctor Patents Latipat Iberoamerica Latin America Patent Database This manuscript is accepted for publicación in World Patent Information (0172-2190) The Latipat project unifies patent information from 20 Ibero-American countries making this content available and free of cost via several major public patent search systems: namely Espacenet, Patentscope and Invenes. These different accesses are presented and their data coverage is analysed. A comparison showed that, although the patent information comes from the same origin, the country coverage and actuality of the patent information varies substantially in the three compared search systems. Regarding the technology coverage, an exemplary search for nanotechnology patents revealed different results depending on the keyword and classification support of each search system. 2016-05-11T11:02:51Z 2016-05-11T11:02:51Z 2016-05-11 info:eu-repo/semantics/preprint 0172-2190 http://hdl.handle.net/10481/41216 eng info:eu-repo/semantics/openAccess
