> FEATURED MODULES
Agentic AI for all sides of patent infringement.
Each module for a specific job — avoid, defend against, or find infringement. Agents do the evidence work; attorneys make the calls.
Infringement Analysis
Find who's using your patents — for a single patent or across your entire portfolio. Agents map product features, technical documentation, and public disclosures element-by-element against your claims.
Single Patent or Portfolio Mode: from one matter
to thousands of assets at once
Product Pages: specifications, manuals,
marketing materials
Public Disclosures: press releases, regulatory
filings, technical publications
Invalidity Analysis
Defend against infringement letters, test specific prior art hypotheses, or assess your patent's legal strength before asserting. Agents search the entire prior art landscape and return results you can steer - not a flat list of references.
Patent Database: +180M across +100
jurisdictions
Scientific Literature: journals, standards,
conference papers
Internet Archive: archived pages and
technical docs back to the 1990s
Freedom to Operate
Avoid the lawsuit. Agents break your product or planned launch into patentable features, then surface the patents you might infringe - ranked by risk, with traceable evidence per feature.
Feature Decomposition: agent-driven breakdown
of your product or launch
Risk Ranking: each feature scored from
cleared to high-risk
Source-backed Evidence: press releases,
regulatory filings, technical publications

03
Evidence Gets Mapped
Agents reason through every claim element and map it to the supporting source, with citations you can open, audit, and defend.

> WHAT OUR CUSTOMERS SAY
Trusted by IP teams that
"Stilta has moved incredibly fast. Only a few months in, the major parts of IP management are already integrated, and we generate competitor and infringement reports across teams that keep us many steps ahead."
Dr. Kerstin Joos
Head of IP & Legal R&D, KUKA
"When you can analyze 10x more patents for commercialization risk, you don't just get more efficient, you make better decisions. Our attorneys focus on what matters most to clients, backed by top-tier FTO assessments that protect them from costly infringement."
Joakim Hernström
CEO, Bergenstråhle and Partners
"In a recent project I gathered defensible evidence on more than two patents in a single day, work that would normally take a week."
Per Wendin
ex-Head of IP, Spotify
"At Mannheimer Swartling we partner closely with Stilta to deliver the strongest possible patent litigation services to our clients."
Oscar Björman Possne
Partner, Mannheimer Swartling
"Using Stilta has given me a significant competitive advantage in the market."

> FUNDING ANNOUNCEMENT · MAY 19, 2026
Stilta raises $10.5M to redefine patent work.

Play
Round led by Andreessen Horowitz. Stilta is also backed by Microsoft, Y Combinator, and the founders and operators of tens of unicorns.
> ENTERPRISE STANDARD
Security built for confidential IP work
Patent work routinely involves unpublished inventions, deal-sensitive product plans, and client secrets. Stilta is built by engineers who deployed AI in security-reviewed enterprise environments at McKinsey and QuantumBlack. We brought that same bar into Stilta from day one.
That means zero AI training on your data, per-tenant isolation by default, privileged work product never leaving your team, and your choice of US or EU data residency. Every model provider we work with is bound by separate confidentiality terms, so your unpublished inventions never enter someone else's training corpus. Standard enterprise controls - SAML SSO, audit logs, encryption at rest and in transit, regular penetration testing - are built in by default.
