Patlytics, an AI-native end-to-end patent platform, has raised $40 million in Series B funding led by SignalFire. The platform supports the full patent lifecycle from invention disclosure and drafting to prosecution, infringement detection, and litigation workflows with citation-backed, hallucination-free AI. The capital will fuel global expansion and product enhancements in life sciences and SEP analysis.
Patent AI Funding Wave Builds
The raise follows a flurry of investments in AI patent tools. Solve Intelligence secured a $40M Series B in December 2025, while DeepIP raised $25M Series B (total $40M) in March 2026. Patlytics differentiates with its unified platform covering portfolio management and pruning, areas where peers focus more narrowly on drafting or search. This timing signals investor conviction in AI automating complex IP processes.
IP Workflows Face Cost Pressures
Law firms and in-house teams at Fortune 500 companies like Sanofi, Nissan, and Rivian handle rising patent volumes amid $200B+ IP industry pressures. Manual processes lead to long cycle times and high costs, with drafting alone costing thousands per filing. Current general AI tools like Harvey frustrate IP specialists due to inaccuracies in domain-specific tasks. Patlytics targets AmLaw 100 firms, already serving 40% of them.
Citation-Backed AI Handles Full Lifecycle
Patlytics integrates 250M+ non-patent literature for prior art searches and offers modules for office action analysis, claim charting, and invalidity work. Unlike fragmented tools, it unifies invention disclosure to litigation with SOC 2 Type 2 and ISO 27001/42001 certifications ensuring security for sensitive data. Recent updates include SEP analysis processing 4M+ standards pages and life sciences sequence management compliant with ST.26/XML.
Human-in-Loop Steers Precision Outputs
The platform emphasizes human-in-the-loop agentic workflows, where AI accelerates but experts control outputs. It has processed 129,000+ claim charts and 210,000+ applications/office actions. Customers report 15-20% faster drafting, saving $5k-$7.5k per filing.
As Paul Lee, CEO and Co-Founder, told Business Insider:
"That's a qualification check for us because they have the budget and they're pro-AI."
SignalFire Backs Platform Scaling
SignalFire led the round, joined by Next47, 8VC, Gradient Ventures, Relativity, and others, bringing total funding to $65M. This growth capital mix validates Patlytics' traction with top-tier law firms like Quinn Emanuel and corporations including Meta and Ford. Investors gain from strategic ties, such as Relativity integrations bridging e-discovery to IP litigation.
Patent Analytics Hits $1.34B
The patent analytics market stands at $1.34B in 2026, projected to reach $3.4B by 2032 at 12.3% CAGR. Trends favor end-to-end AI platforms amid surging filings and USPTO support for AI patents. Patlytics positions against incumbents like PatSnap ($500M+ raised) by focusing on U.S.-centric prosecution and litigation tools.
Peers Narrow on Drafting Tools
IPRally ($13M) emphasizes search and classification, while Solve and DeepIP prioritize drafting. Patlytics' broader scope addresses portfolio pruning and global prosecution gaps, including EPO and Asia.
Founders Bring IP and VC Expertise
CEO Paul Lee, ex-Tribe Capital partner, spotted the IP opportunity from VC vantage. CTO Arthur Jen, from Magic Labs ($90M+ raised), filed 15+ patents and handled litigations, directly informing the platform. An advisory board featuring ex-USPTO Director Michelle Lee and Coinbase CLO Paul Grewal adds policy and Big Tech credibility.
Asia-Pacific and EMEA Push
Plans include Asia-Pacific expansion targeting Korea, Japan, and Taiwan, plus a London office for EMEA. Product roadmaps feature AI-native collaboration suites and chem-bio enhancements, building on integrations with RPX and Relativity.
