First, the regionality of patent protection. As far as we apply for a patent in China, after the patent is granted, we can only protect the patent in China. Foreigners use our patented technology scheme to manufacture and sell products in China, and cannot protect their rights through legal channels. What to do! The best way is to apply for our patent scheme in its country, so that it will be protected by the laws of that country. What needs to be explained here is that the country where the patent landed is related to the size of the market and the degree of competition. It is not necessary for us to apply for our patent in all countries.
Second, build a wall for competitors. Obstructing competitors' technical route makes competitors have to take another technical route, which may take several turns to avoid patent protection. Of course, competitors can invalidate this patent by invalidating it, but the cost is very high and the result is not necessarily good.
Third, having more children is easy to fight. You are less likely to win a product infringement lawsuit through a patent, because competitors will also study your patent, not only your technical scheme, but also the scope of patent protection. Therefore, a variety of ways to realize a technical route and a multi-dimensional patent protection strategy for a product from structure to method can give you greater confidence in safeguarding rights.
