Lei Bai Science and Technology said that counterfeit products violated half of its traditional business, and the main purpose was to purify the market by "counterfeiting".

According to Lei Bai Science and Technology's civil complaint, Lei Bai Science and Technology's "anti-counterfeiting" process is to entrust investigators to buy a mouse marked with the word "Lei Bai" in the merchant's shop, and ask the clerk to issue a payment receipt and affix the official seal, and then the notary will notarize and seal the process and the items and bills purchased by the investigators, and the lawyer will present notarized evidence to the court during the litigation.

According to the statistics of China Legal Literature Network, more than 60 cases involving infringement of scientific and technological trademarks in Lei Bai have been published online. The earliest case was decided in June 20 13, and the ruling of the latest case was submitted on July 20 15. Indeed, no lawsuits against counterfeiters have been found.

Lei Bai's fight against counterfeiting and rights protection caused controversy. Several defendants insisted that the increase in the number of cases of counterfeiting in Lei Bai Science and Technology was "inversely proportional" to the decline in the performance of its main business, and its intention of "profiting" from counterfeiting was obvious.
