CiteStream is an AI-powered prior art search platform built specifically for patent litigation. We help legal teams, IP counsel, and patent professionals surface the most relevant prior art for any patent — faster and more comprehensively than traditional manual methods.

Patent litigation is high-stakes work. Finding prior art that can invalidate or narrow a patent claim can make or break a case. Yet traditional prior art searches are slow, expensive, and highly dependent on individual expertise. CiteStream changes that. Our platform analyzes patent claims at a deep level and systematically identifies prior art across a vast corpus of patent and technical literature, delivering ranked results with claim-by-claim heatmaps that show exactly where each prior art reference reads on the asserted claims.

CiteStream is built for patent litigators, in-house IP teams, inter partes review (IPR) practitioners, and anyone who needs rigorous, defensible prior art search results. Whether you're at a large firm, a boutique IP shop, or managing litigation in-house, CiteStream is designed to fit into your workflow.

Our team sits at the intersection of patent law and artificial intelligence. We bring together deep experience in patent litigation and IP strategy with a proven track record building large-scale AI and machine learning platforms at leading technology companies. We've been in the trenches of patent litigation ourselves — and we built the tool we always wished we had.
