Understanding a search result

Each Google Patent Search result represents an individual patent. We display results based on their relevance to the specific search terms you\'ve entered. We display a number of details about each patent in the list of results.


Explanation of terms

    * 1.      Patent Title: The title of each entry in the search results is the title of that specific patent.
    * 2.      U.S. Patent Number: The patent office assigns a unique number to each patent.
    * 3.      Filing Date: The filing date is the date on which the patent was filed with the USPTO. The filing date is when the inventors applied for the patent and should not be confused with the issue date, which is the date the patent office granted the patent. If we don’t have a filing date for a patent, this field will be blank.
    * 4.      Assignee name: The assignee is the person or organization to which the rights of the patent are assigned. If we don’t have an assignee for a patent, this field will be blank.
    * 5.      Patent snippet: We include a snippet of text from the patent to show where the specific search terms were found.

      Patent summary: Summarizes all the details we have about the patent, including dates of interest, associated parties and classifications. We also provide a link to view each patent on the USPTO site. The details included vary from patent to patent, depending on what information we have for that patent.
    * 2.
      Claims: Lists the specific claims made by the patent.
    * 3.

大陆地区用不了，只要一搜东西，就无法显示。这是伟大的GFW干的好事。大家如果想用，还是准备代理吧。

能用啊，不过我搜的是“test”

可以用啊。不过与其他检索方式相比结果好像不一样。

另外，“伟大的GFW”是什么东东啊？

不能搜中文

我这里确实用不了，不管搜索什么，马上页面重置，无法链接google，大概过10几分钟才能再连。完全就是GFW的典型屏蔽效果。
如果大家那里可以用，那太好了。可能只有我这里被屏蔽了吧。

哈哈，不错，我这里已经可以查了，看来GFW对google/patents网开一面了。
非常好。
我昨天知道google开通专利搜索时，特意试验过，不能用，刚刚测试没问题了。

目前，google专利检索仅可搜索美国专利，不过将来将扩展到世界各国的专利。

我已经测试过了。
目前只能搜索来自USPTO的专利，不能搜索uspto app的专利。
另外，只能浏览，无法打印下载。
是pdf文档。在文档中用高亮标示出了关键字。

它的排名方式也值得注意。

谢谢，有收获。
