The patent downloaded from soopat Patent Online cannot be opened, in PDF format. Click Open and a dialog box will pop up, saying that it is not a PDF file or damaged, as follows.

soopat is a very useful website, and we all use it. Some people have encountered such a problem before, so this problem is answered in soopat, which is actually caused by the browser used not downloading the file completely. There is a top post in soopat forum called "Solution to not downloading patents normally in this site" (you can go and have a look). For example, when downloading with a 36 browser, you can't directly click the download button of 36, but click the "ie Download" button in the lower left corner of the 36 download interface. That's enough. (If there is a problem when using Maxthon, Window of the World and other browsers, it will be handled in a similar way.)
