Not easy to break.
The main points that prove that a certain technical feature is not common knowledge are as follows:
1. Although the features are the same, they play different roles.
To be specific, you need to explain to the examiner that your folding pages not only hold the wires, but the bolt slots not only prevent rotation, but also have other functions. function; and, this function is not applied in other places; this is the only way.
2. The technical solution achieved unexpected results.
That is, if you use the folding sheet to hold the wire, it has more outstanding advantages than holding the wire in other ways.
3. The technical problem itself is not obvious.
For example, a certain piece of equipment always breaks down, and no one knows why it breaks down. Through creative work, you find that the wire is the cause of the failure; by simply folding and closing the wire to hold it, you can Solve problems that have been unsolvable before.
If none of the above conditions are met, it will be difficult to grant a patent.
