1, the first time to get mass production. After purchasing an invention patent in advance, an enterprise or individual can understand and abide by the provisions of the patent right in advance, and must not infringe upon the intellectual property rights of others, but also need to protect their own intellectual property rights, because by purchasing a patent before invention and knowing the provisions of the patent right, mass production can be realized in the first time. Buy a patent after invention, because you need to understand and abide by the provisions of the patent right, so you can't get mass production at the first time, so it is good to buy a patent before invention.
2. Save time by applying before invention. The patent law has detailed provisions on the scope of not granting patent right, whether the obvious lack of technical content can not constitute a technical scheme, whether there is a lack of uniformity, whether the application documents are complete and whether the format meets the requirements, etc. It takes 2-3 months to handle this process. If you apply in advance, it will not only solve the requirements stipulated in the patent law but also save the invention time, so it is good to apply for a patent before invention.
