As is seemingly always the case with Spanish data on Espacenet, the data is quite sparse, and as is often seemingly always the case, the "priority date" listed with the Spanish patent on the inventor's name-based hit list is actually the filing date of the Spanish patent itself. That is, we always find an earlier filing date, or several earlier filing dates, of an analogous patent, or of several patents. Pulication date info is being treated both as date granted and as publication date.
