Of course, German patents can be searched and downloaded from the German Patent and Trademark Office (DPMA) website.
You can find it directly on Baidu "German Patent and Trademark Office". The URL is not posted here. The page of the German Patent and Trademark Office (DPMA) is in German and can be switched to the English interface.
Of course, the European Patent Office website can also be downloaded, but the patent documents are not very complete, and individual PDFs still have to be downloaded from the German Patent and Trademark Office.
Steps:
1. Go to the homepage of the German Patent and Trademark Office (DPMA) website and click "english" in the upper right corner to switch to the English interface.
2. Click "Patents and utility models"
3. Click "Beginner's search"
4. Enter relevant information to search. For example, document number, title, IPV classification, etc. .
5. Click on the retrieved literature information.
6. Click on the PDF file icon to download.
Of course, it will be easier if you understand German. . . .
