Compared with mobile phones with thousands of yuan, a few to dozens of dollars of mobile phone cases may also meet people's expectations for "new". According to the Tianyancha App, there are currently more than 16,000 patent applications related to mobile phone cases in the mainland, and more than 8,300 have been authorized. Among all the application information, there are more than 7800 designs, 6200 utility models and nearly 2100 inventions.
Since 2012, there has been a rapid upward trend in mobile phone case patent applications, with the number of applications reaching a peak from 2018 to 2021, with more than 2,000 applications per year. In addition to many different appearances such as armor, constellations, dolls, transformers, etc., there are patents that try to give the mobile phone case various functions, such as automatically detecting the landing of the mobile phone to protect the mobile phone from being broken, solar charging the mobile phone, ensuring that the mobile phone quickly floats after falling into the water, and ultraviolet disinfection of the mobile phone.
