Signal Engine — Patent Intelligence Platform

Everything you need to understand
what your patents actually mean.

PatentSignal goes deep on the patents you have — claim structure, prosecution history, citation networks, and strategic gaps. Analysis grounded in source text, not generic AI summaries.

Built for IP professionals at every stage

Whether you bill by the hour or manage a portfolio in-house, PatentSignal fits your workflow.

Opinion work in minutes, not hours

Compress claim mapping and prosecution history review from hours to minutes. Every conclusion is traceable to source text you can cite in your opinion.

Professional-grade without enterprise pricing

Solo practitioners and small firms get the depth of tools that used to cost $500+/month — without the IT audit, vendor onboarding, or managing partner approval.

Output you can defend

PatentSignal shows the reasoning, not just the conclusion. Claim-level attribution means you're not accepting AI output on faith — you're reviewing structured evidence.

Reduce outside counsel spend

Run a first-pass analysis before engaging outside counsel. Arrive at every conversation with structured insight, not blank-page questions. Lawyers bill $400+/hour.

Answers for internal stakeholders

When the CTO asks "what does our patent actually cover?" — give them a real answer, fast. PatentSignal translates claim language into understandable scope assessments.

Fits your budget, no committee required

At $49/month, PatentSignal is an individual expense — not a procurement event. Sign up, run an analysis, and justify the ROI on day one.

Understand what you actually own

You filed patents. Now what? PatentSignal breaks down exactly what each claim covers, where prosecution history created risks, and what your IP position actually means in practice.

IP due diligence without the bill

Evaluating a company's patent portfolio? Run a structured analysis before you call outside counsel. Understand citation networks, prosecution patterns, and key claims independently.

Surface continuation opportunities

PatentSignal identifies unclaimed subject matter in your existing patents — continuation opportunities that might be worth filing before the priority window closes.

The Signal Engine

Most AI patent tools treat documents as flat text. Claims have structure. Rejections map to specific limitations. Prosecution history has narrative arc. PatentSignal is built around that structure.

1

Add your patent

Upload a patent or enter a publication number. PatentSignal pulls in the full document record automatically — no manual copying.

2

The Signal Engine goes to work

Our proprietary processing pipeline reads the patent the way a practitioner does — understanding claim structure, prosecution context, and technical scope, not just keywords.

3

Analysis grounded in source text

Every output — claim scope, prosecution risk, continuation gaps — is tied to specific language in the document. You see the evidence, not just the conclusion.

4

Your patent packet, ready to explore

The result is a structured patent packet you can query, revisit, and share. Run analyses, ask follow-up questions, and export — all without starting over.

Claims Analysis

Structured breakdown of every claim — independent and dependent.

PatentSignal parses the claim tree, maps limitation dependencies, and assesses relative scope. You see which claims are the load-bearing ones and where narrowing language creates risk.

  • Independent vs. dependent claim identification with limitation counts
  • Scope assessment — relative breadth visualized per claim
  • Defined term extraction from the specification
  • Examiner-level claim dependency map for prosecution context
  • Signal Engine insight: which claims survived vs. were added during prosecution

Signal Engine: Claim 1 is the broadest independent claim. The "configured to receive" limitation was narrowed in the Oct 2021 amendment — see prosecution history for prosecution disclaimer risk on passive reception methods.
Prosecution History Analysis

Office actions, amendments, and examiner arguments — in one timeline.

PatentSignal reconstructs the prosecution history so you can see exactly how the claims evolved. Every office action is matched to the claims it targeted. Every amendment is annotated with its strategic context.

  • Full prosecution timeline from filing to allowance
  • Office actions mapped to specific claim rejections (§102, §103, §112)
  • Amendment analysis — what changed and why it matters for scope
  • Prosecution disclaimer risk flags on claim language
  • Examiner argument patterns across multiple rejections

Patent Chat

Ask anything about your patent. Get answers grounded in the actual text.

Patent Chat is a contextual Q&A interface powered by the Signal Engine. Every answer cites the specific claim language, specification paragraph, or office action text that supports it. No hallucination, no generic summaries.

  • Ask about claim scope, prosecution strategy, or technical context
  • Every answer includes a source citation — traceable to the document
  • Ask follow-up questions to drill into specific limitations
  • Understands prosecution history context — answers reflect how claims were amended
  • Persona modes: attorney, business stakeholder, technical reviewer
PatentSignal — Patent Chat
You
Does claim 1 cover a method where the ML model is updated in real-time?
PS
Likely not. The Feb 2021 amendment added the "wherein processing occurs within 50ms" limitation specifically to distinguish Smith — and the examiner's allowance reasons referenced this as the key differentiator for batch vs. real-time architectures.
└ Col. 8:12–18 & Feb 2021 Amendment, p. 4
You
What about claim 7 — same issue?
PS
Claim 7 uses different language — "substantially simultaneously" rather than the 50ms threshold. This may have broader coverage but was not subject to the same amendment history. Worth reviewing with counsel.

Citation Analysis

Forward and backward citation networks — who cites yours, who you cite.

Citation patterns reveal competitive dynamics. Who is building on top of your patents? What prior art did your examiner rely on most heavily? PatentSignal maps the network and flags what matters.

  • Forward citations — who has cited your patent since grant
  • Backward citations — prior art the examiner relied on
  • Examiner-cited vs. applicant-cited art distinguished
  • Competitor filing patterns visible in citation network
  • High-influence nodes flagged — the prior art that drives most rejections in this tech space

Continuation Gap Analysis

Unclaimed subject matter in your patent is a filing opportunity you might be missing.

The specification often describes more than the claims protect. PatentSignal identifies embodiments, configurations, and methods disclosed in the spec but not claimed — potential continuation targets before the prosecution window closes.

  • Identifies disclosed embodiments not covered by any current claim
  • Prioritizes gaps by strategic value and prosecution feasibility
  • Flags specification language that could support new independent claims
  • Shows which dependent claims could be elevated to independent
  • Useful for pre-licensing portfolio hardening
PatentSignal — Continuation Gaps
Identified continuation opportunities
3 found
Edge processing variant
High priority
Spec describes edge-node processing at col. 12:4–22 but no claim covers this embodiment. Competitor US 11,503,211 filed in 2022 targeting this exact architecture.
Multi-threshold cascade alert
High priority
Claim 3 covers single threshold. Spec discloses multi-stage cascade (col. 9:14–31) as a preferred embodiment — unclaimed.
Training data provenance tracking
Medium
Spec mentions audit trail for training data (col. 15:8–14). No claim element addresses this. Increasingly relevant post-2024 AI disclosure requirements.
