What does detailed description mean? Video Transcript

We have made it to the detailed description section. The detailed description section is basically a write up that supports your claims. Everything that you said in your claims should be in the detailed description and should be explained in the detailed description. Any definitions that will help to read or understand what you meant in your claim should make it into the detailed description. The definitions must be written broadly so that they cover all the different aspects of what those words mean that you made that [unclear] in your claim, both your independent and dependent. The way you write a detailed description is to start with your figures. Hopefully, the design of your figures tells a story of your invention to a federal jury or to a potential reviewer of your patent application so that everything in your claims is already shown in those figures. You describe each figure at a time. You describe what the figure shows, how all the different elements are interconnected to each other, what the figures illustrates in terms of operations. You want to make sure everything that you write has a nexus to your claims. If you have done your figures properly, they have already illustrated all the things that are in your claims. Therefore you just need to go figure by figure explaining what things are showing. You might have a process flow or two at the end which take any method claims that you have and tie them structurally back to the figures that have structures shown in terms of the environment the invention operates in. So the detailed description should be clear. It should be written without too many admissions. Do not mention anything about the prior art, but really what your invention is, how it works, what are the ways that people can make those claims and they can use of your invention. Really, you also need to disclose the best mode, the best form that your invention can be practiced. That is a legal requirement. You need to disclose that the best mode for this invention is to practice it this way or that. It could be done illustratively in the figures as well. You need to make sure the description provides enough support so someone who is skilled in the art can make and use your invention. So the guideline is to take your claims and your figures, make sure you described your figures, make sure you supported your claims and everything you have labeled in your figures should be supported in the specification of the detailed description section. is a website of Raj Abhyanker, a professional U.S. Patent Law firm, see: for more.
