Speaking of postgraduate entrance examination, I believe everyone is familiar with it. When it comes to the materials for the postgraduate interview, many people will think of "papers". However, in recent years, core journals, SCI, EI and other journals have strict requirements, extremely low pass rate and high cost. Therefore, after breaking the "paper-only theory", many people turned their attention to the "patent" with relatively low cost and easier to pass the examination as their extra points. Postgraduate entrance examination interview, patent has advantages. Judging from the time period of patent application, it takes about 2-3 years for invention patent, 8- 12 months for utility model patent and 6-8 months for design patent, all of which need a long time and need to be prepared in advance. Patent applications that have won honors such as scientific and technological progress awards or scientific research achievements can basically be directly guaranteed.
