A statistical data released by Patent Result, an international professional patent investigation company, reveals the gap in the number of patents between BYD and Tesla. From 2003 to 2022, Tesla has applied for a total of 836 patents. Although this number is not low, it pales in comparison to the number of BYD's patents. The striking fact is that BYD applied for more than 13,000 patents during the same period, which is even 15 times the number of Tesla patents.
