  1. Claims

Claims are the exclusive right conferred by the grant of a patent. Only the patent claims define the scope of protection granted by patent. Hence the claims are the heart of a patent, in that they define the limits of exactly what the patent does, and does not, cover. That is, the patentee has the right to exclude others from making, using or selling, only those things which are described by the claims. The rest of the patent specification only helps explain the invention in detail. Claims define the contours of the features of the product or process for which Govt. gives legal rights when the patent is granted, as a reward for disclosing the invention by way of filing the Patent application. Hence Claim drafting is very important and has to be done by a professional.


The abstract is a short summary of your invention, no more than a paragraph in about 150 words. Think of it as a condensed version of your patent where you can abstract – or take out and focus on – the essence of your invention.
