The key components of the equipment have been patented. How to declare the whole patent?

There is something wrong with your patent strategy. If I were you, I would only apply for a patent (mainly from the economic point of view, there is no substantial difference), but including all these, this is the strangeness of the patent law.

As you said, you have applied for the module (small structure patent), and now you want to apply for the whole one. If there is no priority, you can claim the domestic priority of the previous small structure patent (you have to pay an official fee of 150, but the risk is that your things will be regarded as withdrawn). Add them as your priorities.

Can be written as: 1, a module.

2. Another module.

3. a machine, including module a and module b, and the relationship between a and B. ..

Of course, it depends on whether your small structure patent is open or not.

At present, for convenience, you can write a patent separately.

Needless to say, the instructions are all written.

Claim, or:

1, a module.

2. Another module.

3. a machine, including a module a and a module b, and the relationship between a and B.

You can also just write: a machine, including module A and module B, A has. B yes. The relationship between A and B.

Do not ask for priority, save money. It's all your patent anyway. You have nothing to lose.

This is not a big problem, as long as your invention is patented.

The relationship between the components of a combined invention or protection.

The motor part is very useful.

1. It is part of the plan, without which the plan cannot be implemented.

2, the key is to look at the connection and function, the invention no longer has a motor, but the cooperation between the motor and others.
