Are Hong Kong patents protected in Chinese mainland?

Be protected. According to the Patent Law of People's Republic of China (PRC), the patents applied by the Special Administrative Region of China are equally protected as those applied by Chinese mainland. This protection applies not only to the Hong Kong Special Administrative Region, but also to the Macao Special Administrative Region and Taiwan Province Province. Patent refers to the legal system promulgated by a country or region to encourage innovation and protect intellectual property rights, which authorizes the patentee to exclusively use the technology, products and designs invented or created by him within a certain period of time.
