However, when purchasing intellectual property rights, we should pay attention to the fact that the patent is effective and has a certain advanced level of technology, and it is best not to be an appearance patent; Because the innovation of design patents is not high, it is difficult to reflect the technological advancement of enterprises, so it is not recommended to regard design patents as the core independent intellectual property rights of enterprises. In addition, patents can be linked to scientific research projects and belong to the research results of scientific research projects; Patents can be embodied in actual products, and products have a high sales ratio.
