Pirated mobile phone cases can be considered pirated. Piracy refers to the act of producing, selling, copying, and disseminating other people's original works or intellectual property works without authorization or permission. As a commodity, mobile phone cases are also protected by intellectual property rights. Original designers or brands will spend a lot of time and energy and invest a lot of costs when designing and producing mobile phone cases. Therefore, unauthorized or unlicensed piracy infringes the intellectual property rights of the original designer or brand owner. At the same time, piracy will also harm the interests of consumers, because the quality and service life of pirated goods are often not as good as genuine goods, and may even cause potential danger to personal safety. Therefore, we should support the protection of intellectual property rights and not buy pirated goods, nor produce, sell or disseminate pirated goods.
