The first innovative invention is also a groundbreaking invention. This refers to a brand-new technical scheme, which has never been seen in the history of technology at home and abroad. This invention has created a new milestone for the development of human science and technology, and it is an absolutely novel invention. For example, the compass, printing, steam engine, electric light, telephone and other inventions that have left brilliant footprints in the history of human invention belong to the first innovative invention.
2. Improved invention patents
The invention of performance improvement refers to an improved technical scheme that improves its performance and makes it have new functions while maintaining its unique performance on the basis of the existing technology. Compared with the first innovative invention, the improved invention depends more on the technological achievements of predecessors. Most inventions belong to improved inventions.
3. Combination of invention patents
Combinatorial invention refers to a technical scheme that combines the characteristics of the prior art to achieve different effects. For example, the engine, tires, carriage and steering wheel are combined into a car, and the combined result has completely different technical effects from the original four components. In the modern society with increasingly advanced science and technology, the invention of combination is more important and indispensable. The recombination of the original products or methods and the flexible application of the original technology can sometimes produce unexpected effects and even raise the existing technology to a new stage.
4. Applied invention patents
Practical invention refers to the invention produced by applying the known technology in a certain technical field to a new field. This new application can also produce unexpected technical effects. For example, we all know washing powder. Some characteristics of washing powder have been studied. Using washing powder in animal husbandry as feed additive to feed pigs can achieve the purpose of fattening. The new use of washing powder is the application of natural inventions.
5. Selective patents for invention patents
The selectivity of invention patent is the invention of some technical schemes selected from many public technical schemes. Selective invention is a common form of invention in the field of chemistry. For example, under standard atmospheric pressure, the output of substance A usually increases continuously at 50 ~100 C, but according to further experiments, if it is set at 70 ~ 80°C, the output of substance A obviously increases greatly. The invention is a selective invention in a wide temperature range. For those who want to broaden the scope of patent protection, but do not have enough examples to support it, it is very simple to choose an invention based on the original invention.
