If it is the logo that should be provided by laws and regulations, but your goods are not available, it is best not to sell it on Taobao shelves. For example, goods must be certified by HDMI. Putting this illegal commodity on the shelves will be punished by Taobao, and if it is targeted by professional counterfeiters, there may be relatively large losses.
HDMI is a compulsory patent certification. If the customer uses HDMI technology or HDMI interface, it means that the product uses the patented technology of HDMI and can only be used with the authorization of HDMI Association, otherwise it will be regarded as infringement.
