A Workable Approach for Drafting Patent Claims

Stage 1: Input 

At the outset, the system needs to receive some form of input before it can perform any meaningful function.

— This input might come from an external device, internal memory, user interaction, or environmental sensors.

— Regardless of the source, the system must first collect or acquire data to act on.

Stage 2: Processing 

Once the input is obtained, the next stage involves transforming or manipulating that data.

— This processing phase is often where the inventive concept lies.

— It could involve a single operation or multiple steps that produce an intermediate or final result.

Stage 3: Output 

After the data has been processed, the system produces an output that reflects the results of its operations.

— This output could take various forms: transmitting data to another system, displaying information, generating a signal, or performing an action such as activating a control mechanism.

This approach is proven effective for several reasons:

1. It is versatile — it works for a broad range of technologies, including software, control systems, machine learning models, sensors, telecommunications, and more. Essentially, if an invention can be broken down into sequential steps, this approach can be applied.
2. It’s systematic and intuitive, making it easier to articulate how the invention works and to structure claims around it.
3. It ensures the invention is claimed from the perspective of a single entity or device, which is critical for avoiding complications like multi-party or divided infringement scenarios

Why Use the IPO Approach?

The IPO framework simplifies claim drafting by providing a clear, step-by-step flow that mirrors how most inventions operate. By dividing the invention into Input, Processing, and Output, you ensure the claims are logical, precise, and focused on a single device or entity.

This approach is not only adaptable to a wide range of technologies but also helps mitigate the risks associated with multi-party infringement claims.

In short, the IPO method offers a straightforward and reliable way to draft patent claims that are both clear and effective.
