Combining two existing technologies or products to form a new technology or product, can this new technology or product apply for an invention patent?

The most classic example you want is an American pencil with an eraser on its head. Originally, everyone used ordinary pencils. Then someone thought of putting an eraser on it. Whether this technology is an invention has been debated for a long time. \x0d\ This technology is called combinatorial invention in the patent law. Whether it can be an invention depends on whether it can achieve unexpected results. If it is only a simple superposition of the two technical effects, you can't apply for a patent. But if it is successful in business, it can be directly judged as a patent, because it has always met people's needs. Just like the pencil eraser on it, it was very popular with everyone, so it was later patented. \x0d\ Patent judgment is often not just a technical problem. If you have a suggestion for a new product, you should apply for a patent instead of considering the technical problems first. Of course, you have to entrust a professional organization. \x0d\ The technical scheme can also be protected by trade secrets, and no patent application is required. It's like Coca-Cola's recipe. However, the market reaction of MP4 is relatively quick, so it is better to apply for a patent as soon as possible.
