Does the more patents granted by a country mean the higher the technology of a country?

Not exactly. Compared with the number of patents, patent quality is more important. Only truly effective patents can reflect a country's technological accumulation.

For example, in our country, the pursuit of quantity a few years ago, the patent for utility model was only a formal review, and now the quality of the patent is gradually improving, and the novelty and creativity are also slowly being reviewed.
