General Analysis of IPC Classification Revision in Electrochemistry Field
[Purposes]In recent years,the field of electrochemistry has developed rapidly,and new IPC classification numbers are urgently needed to match the development of the industry.[Methods]This pa-per compares the classification changes in this field before and after the revision,clarifies the newly added technical details,and compares the classification of related case.[Findings]In the revised electro-chemical field,its IPC classification number can more reasonably and accurately classify the technical schemes in this field.[Conclusions]This paper clarifies the technical branches in the field of electro-chemistry,which is helpful for practitioners in the patent industry to understand the technical branches in this field and improve the retrieval efficiency.
