What Aistemos does
Aistemos (formerly Cipher) is a London-based private software company that built an AI-powered patent classification platform designed to help large patent-owning organizations analyze and manage global patent landscapes. Its core product, Classification, uses proprietary machine learning and natural language processing to read 44M+ active patents worldwide, processing more than 60 million patents per hour and analyzing 200,000 data points per patent. Organizations use the platform's Custom Classifier Builder to define their own technology taxonomies, train classifiers on positive and negative patent sets, and refine results via similar-family suggestions, eliminating manual tagging and complex Boolean queries. The 9,000+ classifiers built by customers integrate directly into LexisNexis' PatentSight+ platform, the flagship IP analytics solution into which Aistemos was acquired in 2024.
Aistemos served six horizontal customer segments — corporations, law firms, business consulting firms, investors, government, and academia — with a primary focus on patent-owning enterprises. Named customers included Red Hat and ARM, with ARM publicly reporting a reduction of nearly 50% in 10-year patent expenses after adopting the platform. The go-to-market was enterprise field sales with quote-based annual subscription pricing, supplemented by content marketing, webinars, the Classification Vision Podcast, and industry events such as the Global IP Impact Summit. The company operated with 11-50 employees and was capitalized with a single disclosed funding round of approximately $3.94M led by Beringea in 2018, prior to the LexisNexis acquisition.
The business model was subscription-based enterprise SaaS with annual billing and quote-based pricing, monetizing access to the classification engine and the integrated PatentSight+ workflow. Following the 2024 acquisition by LexisNexis, Aistemos' technology operates as the AI Classifier layer within PatentSight+, shifting the commercial model from standalone subscriptions to an embedded capability within a larger IP analytics platform.
