Next, Lightbringer pairs each project with a domain‑expert patent attorney who drafts the application using a suite of proprietary AI tools trained on hundreds of thousands of patents. Throughout the process, built‑in patent strategy builders guide users in articulating claims to attract investors and maximize portfolio value. With seamless integration of human expertise and purpose‑built AI, purpose‑trained by in‑house attorneys, this end‑to‑end solution handles complex technical content and legal language, manages custom cookie‑like data inputs for each case, and tracks application status in real time, all via a single interface.
