Transformers-based Abstractive Summarization for the Generation of Patent Claims. A patent is a kind of intellectual property that grants its owner the authority to exclude others to make, sell, or use an invention for a fixed amount of time in exchange for sufficient disclosure of the invention. Each patent is made of five main parts: abstract, background, summary, description and claims. If the patent is accurately written, only the claims formulation task is up to the Intellectual Property (IP) attorney. The most important claim is the first one. It is composed of a single sentence, has to set out the distinctive features of the invention and underline the differences from the inventions already present in the same or similar field.
