What makes us different

Patent strategy requires reading the patent. We built the tool that does the reading.

Most patent intelligence platforms answer one question: what else is out there? That's a prior art search problem. They solve it at scale, across millions of documents, broadly.

PatentSignal answers a different question: what does this patent actually do for you? We go deep on the patents you own or need to understand — not wide across millions you don't.

Not this
Prior art search at scale
PatentSignal doesn't index millions of patents for keyword search. Other tools do that well. We do something they don't.
Not this
Generic AI document summarization
A general-purpose LLM reading a patent produces plausible-sounding summaries. PatentSignal produces claim-level analysis with prosecution history attribution.
This
Deep IP strategy for patents you own
Claim interpretation, scope analysis, prosecution history flags, competitive positioning, EOU mapping — for 1 patent or a portfolio. The layer between owning a patent and using it.
Why it matters

The gap between
owning a patent and
using it strategically.

Most companies file patents and then stop. The claims get reviewed once during prosecution and never again. PatentSignal is the tool that sits between your patent portfolio and every decision that depends on it.

90%
Less time on initial review
What took a paralegal half a day takes PatentSignal under five minutes. Same output, without the billable hours.

The Signal Engine

Built for IP professionals.
Not for data scientists.

Every analysis runs on a purpose-built intelligence layer trained on patent language, claim structure, and prosecution history — not a general-purpose chatbot you have to prompt-engineer.

Claims Analysis

Independent and dependent claims parsed, mapped, and evaluated for strength, breadth, and potential invalidity vectors. Includes a color-coded dependency tree.

Prior Art Exposure

Surfaces published art, pending applications, and public disclosures that overlap with your claims. Supports AIA and pre-AIA timelines with grace period analysis.

Market Landscape

See who else is filing in your technology space. Assignee clusters, filing velocity, CPC classification distribution, and geographic coverage — all from the patent record.

Patent Q&A Chat

Ask anything about your patent in plain language. Claim scope, prosecution history estoppel, limitation interpretation — every answer is cited to the specification.

We used to spend two hours per patent just doing initial triage. PatentSignal gets us to the same place in four minutes. That's not an exaggeration — I timed it.
