Search Strategies for Claims with Stacked Technical Features During Patent Examination
[Purposes]In response to claims with stacked technical features,it is difficult to obtain effec-tive comparison documents using conventional searching methods.This study aims to explore how to ex-pand search approach,extract accurate keywords,and quickly obtain effective comparison documents.[Methods]Starting from patent application,this paper analyzes limitations of conventional search strate-gies,proposes a search strategy that transforms discrete technical features into keywords of functional ac-tuator,and further summarizes other types of mechanisms that may be written with stacked technical fea-tures.[Findings]The above search strategy significantly improves the speed and effectiveness.[Conclu-sions]For claims written with stacked technical features,discrete technical features can be transformed into keywords of functional mechanical actuator based on their motion transformation form.
