Practicality means that the theme of the patent you apply for must have a real effect on people or society. If it violates social morality or is useless, the United States will not grant a patent. In this regard, you should provide detailed explanations and invention descriptions for the patented works you apply for, so as to ensure that you can provide detailed and clear information to American auditors and the relevant scheme for implementing the patent. If there is no correct patent implementation plan, the practicality of the patent will also be affected, and it will also affect the judgment of American auditors.
Creativity Since you want to apply for a patent, the theme of the application must be attractive and creative. Ideas and works need to be unique and innovative. If the subject matter of the application has relevant application history or usage records before, then the patent application will be rejected by American examiners, and the protection of American patents on patented works will also ensure its uniqueness and novelty. Besides creative considerations, the theme of the patent application needs to be related to the development of contemporary science and social technology. If it violates the existing technology, the patent application will be rejected.
Realizability needs to pay attention to the patent work you apply for, whether it is design or connotation. And this patent can be realized in real life. If it's just a wild imagination that can't be realized, then the patent application will be rejected. Therefore, when inventing, we should not only consider its practicality and creativity, but also ensure that this patent can be implemented.
