Oskar Block<\/a> named Patlytics and Solve\u2019s Charts product as his closest competitors, while arguing that most other patent-AI tools \u2014 including the better-known drafting platforms \u2014 have so far focused on prosecution rather than litigation work.<\/p>\nWhat The Product Does<\/h3>\n
In our briefing, Block demonstrated that, on the invalidity side, Stilta lets a user drop in a patent number and then dispatches a swarm of AI agents to look for prior art across what the company describes as 180 million patents, 250 million scientific publications, and more than a trillion archived web pages \u2014 the latter via an integration with the Internet Archive\u2019s Wayback Machine. The agents also pull prosecution history from the USPTO.<\/p>\n
During the demo, Block walked through an invalidity analysis the platform had run against a wireless-networking patent. After roughly half an hour, the system had surfaced 868 prior art references \u2014 a mix of patents, non-patent literature like product brochures and scientific publications, and archived web pages \u2014 and mapped them against each claim limitation in a claim chart that color-coded the strength of each read.<\/p>\n
A user can drill into any reference to see the source text or the underlying PDF alongside the claim language, and can prompt the agents to go deeper on a specific limitation. Block also showed multiple agent sessions running in parallel against the same patent, including one tasked with drafting the best invalidity theories \u2014 anticipation and obviousness \u2014 from the prior art the system had already pulled.<\/p>\n
Stilta says it has run an internal benchmark showing roughly three times the recall of general-purpose models like ChatGPT, Claude and Perplexity on the same invalidity task.<\/p>\n
Block said the product also handles the mirror-image workflow \u2014 infringement and freedom-to-operate analysis on the assertion and commercialization side \u2014 and that customers can use the platform collaboratively, with multiple lawyers in the same project.<\/p>\n
Customers And Roadmap<\/h3>\n
According to its press release, Stilta formally launched its product in February and already has notable enterprise customers including Roche, Alfa Laval, and Maersk. The release says the company also has signed three of the world\u2019s five largest IP firms as either customers or active pilots.<\/p>\n
In the briefing, Block said roughly two-thirds of Stilta\u2019s customers are corporate in-house IP teams \u2014 across pharma, industrials, and high-tech \u2014 and one-third are law firms focused on litigation. The customer base is split roughly 50\/50 between the U.S. and Europe, he said. Stilta did not disclose revenue, pricing, or customer counts.<\/p>\n
The round will fund Stilta\u2019s first hires beyond the four co-founders, with engineering and go-to-market hires in Stockholm and plans for a New York office by year\u2019s end.<\/p>\n
Longer-term, Block said, Stilta wants to expand from litigation into adjacent IP workflows and eventually become \u201cthe full IP operating system\u201d for both corporate IP teams and law firms \u2014 the same kind of platform pitch Patlytics and Solve are also now articulating.<\/p>\n
Block said that starting in litigation, where accuracy demands are highest, makes the move into lower-stakes workflows easier rather than harder.<\/p>\n
\u201cPatent litigation runs on labor-intensive workflows that haven\u2019t meaningfully changed in decades,\u201d Haber, the Andreessen general partner, said in the press release. \u201cStilta automates them and, in doing so, becomes the system of record for how enterprises protect and monetize their most valuable intangible assets.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
