We have collected a representative sample of patent data from various BRICS countries. 

We used a limited interpretation of the BRICS member countries and conducted an analysis of patent activity in the following countries: Brazil, India, China, Russia, and South Africa.

As data sources, we used the websites patents.google.com and patentscope.wipo.int. 

Since the data in these sources is presented unevenly, we simultaneously used data from different sources to achieve maximum completeness in data collection.

For data extraction, we used the search query ```teaching AND education``` to retrieve results from the patents.google.com database. In the case of patents registered with the Indian Patent Office, the search results on patents.google.com did not exceed 200 patents. 

Therefore, we conducted an additional search in the patentscope.wipo.int database. 

Additionally, the query was supplemented with search conditions in the form of the query ```teach OR pupil OR school OR classroom OR lesson OR education```, where the operator ```OR``` was used to include documents with any of these words in the search results.
