Patent offices around the world are required by law to make information about inventions public. This applies to both existing and expired patents. The most convenient way to access them is via the Internet.
Instructions
Step 1
To gain access to Russian and Soviet patents, enter the following url into the address bar of your browser:

Step 3
All 2.5 million patents of Russia and the USSR in the list are grouped in hundreds of thousands. Select from the list which one interests you.
Step 4
Similarly, select the desired ten thousand, one thousand, and then one hundred documents.

When the search circle is limited to one hundred, a list of the documents included in it will be displayed. Choose the one you want. If a patent is received before the early nineties of the twenty-first century, it is presented only in graphic form, in TIFF format. You will have to download from one to five files with a volume of about 80 kilobytes. Newer patents are additionally presented in text form and can be read directly on the website. But this does not negate the ability to download them as images if desired.
Step 6
To view TIFF files, use the display utility provided with ImageMagick on Linux. Don't confuse it with the Display program included with KDE. In Windows, this file format is opened by the Image and Fax Viewer.

Step 9
