1 Some of them have relatively strong patentability and can be applied for.
There are some that are easier to think of. Applications for inventions are probably difficult to get approved. Applications for utility models can generally be approved, but some of these types of patents can easily be invalidated.
2 The combination of two or more products with strong patentability is when the combination of the two is not easy to think of, or when the combination of the two has unexpected effects.
If the technical features of the combination support each other in function and achieve new technical effects, or the combined technical effects are superior to the sum of the effects of each technical feature, this combination It has outstanding substantive features and significant progress, and the invention possesses creativity. Whether each technical feature of the combined invention itself is completely or partially known does not affect the inventive step. For example, the invention of "cryogenic treatment and electroless nickel-phosphorus-rare earth plating process" is a combination of the well-known cryogenic treatment and electroless plating. The existing technology requires unconventional temperature tempering of the workpiece after cryogenic treatment to eliminate stress and stabilize the structure and performance. In the present invention, after cryogenic treatment, the workpiece is not tempered or aged, but is electroless plated in a plating solution of 80°C ± 10°C. This not only eliminates the need for tempering or aging treatment, but also keeps the workpiece still intact. It has a stable matrix structure and a coating that is wear-resistant, corrosion-resistant and well combined with the matrix. The technical effects of this combined invention are difficult to imagine in advance for those skilled in the technical field to which the invention belongs. Therefore, the invention has creativity.
3 The combination of two or more products is not patentable if the combination is only a variation of a known structure, or the combination is within the scope of continued development of conventional technology and has not achieved the expected results. If the technical effect cannot be achieved, such a combined invention will not be creative.
If the invention is just some well-known products or methods connected together, each still works in a conventional way, and the total technical effect is the sum of the effects of each combination, the technical characteristics of each combination have no functional significance. The interaction relationship is just a simple superposition, or "patchwork", and the invention of this patchwork is not creative. For example, the invention of a ballpoint pen with a digital watch. The invention is to install a well-known electronic watch on the body of a ballpoint pen. After combining the electronic watch with the ballpoint pen, the two still work in their conventional manner and do not support each other in function. They are just a simple superposition. Therefore, the electronic watch and the ballpoint pen are combined. Inventions do not involve creativity.
