摘要
本文通过专利数据库和专利分析软件对我国电动化领域专利进行检索并实现IPC分类分析,得到数据图表。通过分析发现H02J小类,G06K小类,G05D四个小类中专利专利数量基数较小,且其中有很多大组类在本领域申请数量极低,可重点考虑。
Patent database and patent analysis software is used to search patents in the fi eld of electrifi cation in China,and IPC classifi cation analysis is realized,and data charts are obtained.Through analysis,it is found that the number of patents in the four sub-categories H02J,G06K,and G05D is relatively small,and many of them have very low applications in this fi eld,which can be considered.
