We summarize in this page, in chronological order divided by year, all patents classified inside the wiki. This page use as ordering key the publication date, that sometimes is quite late respect to the application one. From an historical point of view using the application date, as done in [[Patent chronology|this other page]], should be more correct, because that date is nearer to the time of invention birth.  Note that none of these dates necessarily correspond to the market introduction of the innovation described by the patent, as there were cases when it occurred both before and after the publication of the patent.
