The initiative is to obtain the monopoly right to implement a certain technology. You can have this technology to yourself, and anyone who uses this technology must get your permission. Technology monopoly will of course monopolize the market. And this monopoly is protected by law. When rights are violated, they can be protected by law. Moreover, patents can give enterprises a favorable position in the competition.
The defense functions mainly include: preventing being sued by others for infringement, improving product popularity, and forcing the other party to withdraw from the competition when competing with other enterprises for the same product. When an enterprise's product is made after improving the patent of others, in order to avoid being involved in infringement disputes and being sued for infringement by others, it can apply for a patent for the product. Generally, after obtaining the patent right, others will probably give up even if they want to sue you for infringement. Play a defensive role and will not fall into the infringement trap created by others. Secondly, patented products can be marked with patent numbers, which will improve the level and technical content of products among consumers and expand the sales of products. Moreover, the same product in the competition, holding a patent can stop the opponent. For example, two companies produce the same product and the product structure is very similar. Another company wants to buy this product. When the quality and price of the two products are being measured, you have a good chance of suing your opponent for infringement with a patent. Ordinary buyers will not be willing to get involved in infringement disputes. Your opponent is facing an infringement lawsuit. At this time, in order to save trouble, ordinary buyers will choose your goods.
