Since 2000, the scale of patent applications in China was growing year by year. Moreover, between 2010 and 2016, there has been a record of a double-digit growth for 7 consecutive years. On the "World Intellectual Property Day" on April 26, 2019, China National Intellectual Property Administration (CNIPA), the competent authority for intellectual property rights in China, brought up the slogan "Quality instead of quantity", hoping to meet a new milestone of patent application quality in China.
