Abstract:The division of technical features is the basis for judging patent infringement.The avoidance in the concept of patent technical characteristics at the legislative level and the diferences in the purposeof interpretation of claims in different contextsand circumstances in administrative judicial practice and the changes in interest motives have resulted in vague rules for the division of technical features in patent infringement litigationand lack of uniform norms.Basedonthethree-element framework of“unit-functioneffect”composed of patent technology features，taking the unity of indivisibility of patent technology unit and independence of technical eficacyas the standard，a“three-step method” is proposed for technical feature division，which involves decomposing the patent technology solution into the smallest unit，determining whether the functional fect of the smallest technologyunit is independent，and combining the smalst technology unit.It is conducive to standardizing the process of determining technical facts inpatent infringement litigation and unifying discretionary standards.

Keywords:patent litigation；technical features；indivisibility
