In patent applications, no additional fees are required when the claims are within 10, but some patents often have more than 20 claims.

1. The function of a dependent claim is to further qualify the claim it cites or to further supplement the claim it cites.

2. You can eliminate dependent claims and only keep independent claims. There is no such thing as moving dependent claims into the specification. It can be understood that you can directly delete the dependent claims that you do not want.

3. Unnecessary technical features recorded in independent claims will make it easy for others to circumvent your patent, making your patent unprotected. If a patent is worth 1 million, if there are superfluous or dispensable technical features in the independent claims, it may affect whether the patent is worth 1 million or worth nothing.

4. Some claims are written with more than 20 claims. There are two possibilities. One is that the patent really needs so many claims; the other is that the patent writer wants to make more extra money and exceed 10 items, they will charge more for each additional item.

5. I hope my answer can be adopted! Thanks! If you have any questions, please add me at 291521962 to communicate.
