Claim chart

A claim chart is like a map that helps you understand if something is new or not. Imagine you are playing a game of memory, where you have to match two pictures that are the same. A claim chart works in a similar way. It helps you to match two things together to see if they are the same or different.

In a claim chart, we have two things that we want to compare: one thing that someone said they invented and another thing that already exists. The first thing is called a patent claim, and the second thing is called a prior art.

The patent claim is like a recipe. It tells you how to make something new and unique. The prior art is like a cookbook. It has many recipes, some of which people have tried before.

The goal of a claim chart is to compare the patent claim with the prior art to see if someone really made something new and unique. If the recipe in the patent claim matches a recipe in the prior art cookbook, then the invention is not new or unique. But if the recipe in the patent claim has some special and unique ingredients that are not in the cookbook, then the invention is new and unique.

In summary, a claim chart is like a memory game where we match a patent claim (recipe) with a prior art (cookbook) to see if the invention is new and unique.
