If you want to dramatically speed up patent drafting without sacrificing quality, Solve Intelligence is a top option. The AI tool uses an in-browser document editor so lawyers can create high-quality patents as fast as possible. It's got an interactive, customizable interface that lets you control how much AI is involved at each stage of the patent filing process. With reported drafting speedups of 60-90%, it's popular among IP firms that want to cut drafting time and expense without sacrificing quality.
Another contender is CoCounsel, an AI legal assistant that automates lots of legal work, including document review and contract analysis. Using OpenAI's GPT-4 technology, CoCounsel can help you find important documents, extract relevant information and create chronologies from case documents. The idea is to free up lawyers to focus on higher-level work by taking over the drudgery of processing data, which could help with patent drafting indirectly by letting you review and analyze documents faster and more accurately.
