Характеристика

Inventionsaredifferentfromscientificdiscoveries.Inventionsmainlycreatethingsthatwerenotthereinthepast,anddiscoveriesmainlyrevealtheexistenceandattributesofunknownthings.

Theinventionisanoveltechnologicalachievement,notsimplyimitatingexistingartifactsorrepeatingtheschemesandmeasuresthathavebeenputforwardbythepredecessors.Atechnologicalachievementcannotbecalledaninventionifitcanbefoundintheexistingtechnologicalsystemintermsofprinciple,structureandfunction.

Theinventionmustnotonlyprovidesomethingunprecedented,butalsoprovidesomethingmoreadvancedthantheprevioustechnology,thatis,superiortotheexistingtechnologyintermsofprinciple,structure,andespeciallyfunctionalbenefits.Inventionsalwayshavebothinheritanceandcreation,andingeneral,theyaremostlyadvanced.
