Patent chronology

We summarize in this page, sorted in chronological order, all patents classified inside the wiki. The order was made on the basis of the application date, that sometimes is quite earlier respect to the publication one used in this page. From an historical point of view this should be more correct than using publication date, because application is nearer to the invention birth and establishes priority over others patents. Note that sometime the application date do not correspond to the priority date, when a patents is later requested in other countries than the original one. Note also that none of these dates necessarily correspond to the market introduction of the innovation described by the patent, as there were cases when this occurred both before than after the applicaton of the patent.
