Stilta - 2026 Pricing, Features, Reviews & Alternatives

Stilta is a cloud-based agentic AI platform built for high-stakes patent work, serving IP law firms and in-house IP teams at global enterprises. Domain agents reason across patents, scientific literature, file wrappers, and decades of archived web content to produce defensible freedom-to-operate (FTO) opinions, infringement reads, and claim charts. Products or planned launches are decomposed into patentable features, with potentially infringed patents ranked by risk and every claim element mapped to traceable, citable evidence. A human-in-the-loop workflow keeps patent attorneys in control: four structured steps are executed by domain agents and audited by counsel before outputs are finalized. All outputs are source-cited across patent jurisdictions, scientific literature, and archived web, and are designed to be auditable and defensible in legal proceedings.

Stilta is deployed in the cloud with a choice of US or EU data residency and per-tenant isolation by default. The platform operates under ISO 27001-aligned information security management, GDPR-aligned privacy architecture, and is built to EU AI Act standards for high-stakes legal work. Security controls include SAML SSO, audit logs, encryption at rest and in transit, and regular penetration testing. Zero AI training occurs on customer data, and all model providers are bound by separate confidentiality terms, ensuring privileged work product and unpublished inventions remain within the team. Competitor and infringement reports can be generated across teams to support ongoing strategic awareness and portfolio management.
