I also want to go abroad, and my grade point is not high. At the same time, I also applied for a patent, which is a practical model, but I intend to apply for an invention patent after improving the product.
First of all, it must help. Patents can show your sense of innovation and certain creativity, and will leave a good impression on the other party, at least tell the other party that you are not that kind of nerd.
But how much specific help depends on two factors, namely, the relevance of this patent to your major and its practicality in reality.
Professional relevance can reflect your academic ability. If this patent belongs to your professional field and more professional knowledge is applied, then this is a very good thing. Patents are the strongest manifestation of your scholarship, and their value is much higher than papers. But the reverse is also true. For example, if you make an electronic thing, but your major is biology, it won't help much.
Practicality in reality is easier to understand. If this is a trivial matter, no matter how high its technical content is, it is difficult for this type of patent to be recognized by the other party.
To sum up, whether it can be of great help depends on how specific the patent is and whether it is practical. Is it in line with your application field? You can get the answer by thinking about these questions yourself. I wish you success!
