楼上两位的检索思路错了，valvetronic的意思是电子气门，这个应该是BMW公司在产生该技术后自行使用的一个合成词，而在专利申请中采用一个未被认知的合成词显然是不明智的，所以说valvetronic应该指的是valve和electronic，然后以这两个词为发明名称检索，另外，BMW是德国的公司，那么在美专局检索也是不明智的，德国人不会要把自己的技术先在美国申请专利，最后，在欧洲专利局进行检索的结果为，五篇德国专利和两篇欧洲专利。 RESULT LIST 7 results found in the Worldwide database for: valve electronic in the title AND Bayerische Motoren Werke as the applicant The result is not what you expected?

这个如果 它申请的肯定是全球都会申请，可是利用你给的这个单词valvetronic 以及巴伐利亚机械制造厂股份公司（Bayerische Motoren Werke ） 我在美国专利局进行检索 结果是0所以 怀疑对于电子气门是不是有更专业的词汇？
