Freedom-to-operate triage — a structured first look at potentially blocking patents, not an FTO opinion. Use when a product, process, or feature is being evaluated for blocking patents, when asked whether anything stops a launch, or to build a claim-chart first pass against the most plausible patents before patent counsel review. This skill never concludes a product is clear to launch.
Freedom-to-operate triage — a structured first look at potentially blocking patents, not an FTO opinion. Use when a product, process, or feature is being evaluated for blocking patents, when asked whether anything stops a launch, or to build a claim-chart first pass against the most plausible patents before patent counsel review. This skill never concludes a product is clear to launch.
This is not a freedom-to-operate opinion. A formal FTO opinion requires a
comprehensive search, full claim construction, and element-by-element
infringement analysis by registered patent counsel. Patent infringement is
strict liability; willful infringement triples damages. A "no obvious blocking
patents" result from this skill means the triage didn't find one — it does
not mean the product is clear.
Instructions
Read ~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md. If it
contains [PLACEHOLDER], stop and direct to /ip-legal:cold-start-interview.
Follow the workflow below.
Run intake (product/process, technical detail, jurisdictions, known patents,
timing).
Run a preliminary patent search if a connector is available (Solve
Intelligence Patents, or other patent-research MCP). Otherwise say
so in the output and proceed with the patents the user has supplied.
For the 2–5 most plausible patents, build a claim-chart first pass against
each independent claim — element by element. Literal read first; flag
doctrine-of-equivalents separately; flag indirect / divided infringement.
List open questions a real FTO study would resolve (enforceability,
prosecution history, IPR outcomes, license availability, enforcement
history of the assignee).
Write the triage memo to the matter folder or practice outputs folder. Apply
the work-product header per role.
End with recommended next steps, a willfulness note (knowledge of specific
patents factors into willfulness if the company proceeds without further
counsel review), and the non-lawyer gate if the role is non-lawyer.
This skill never concludes that a product is clear to launch. If uncertain,
flag — patent counsel decides.
Examples
/ip-legal:fto-triage "an on-device speech recognition model for consumer wearables, US launch first"
/ip-legal:fto-triage
THIS IS NOT A FREEDOM-TO-OPERATE OPINION
The loudest guardrail in the plugin. Say this at the top of every output. Do
not drop it. Do not soften it. Do not let the reader skim past it.
This is not a freedom-to-operate opinion. An FTO opinion is a professional
legal judgment, usually by registered patent counsel, based on a comprehensive
search, full claim construction, and an element-by-element infringement
analysis against each claim of each relevant patent. This triage is a
structured first look at what might be out there. A "no obvious blocking
patents" result means the triage didn't find one — it does not mean the
product is clear. Patent infringement is strict liability; willful
infringement (which can follow from knowing about a patent and proceeding
anyway) triples damages under 35 U.S.C. § 284. The decision to launch, make,
use, sell, or import is a business decision informed by a formal FTO study
and counsel's judgment — not by this triage. A registered patent attorney or
agent evaluates before anyone relies on this for a product decision.
Under-flagging a blocking patent is a one-way door — a product launched, a
deposition a year later, treble damages on the table. Over-flagging is a
two-way door — the attorney narrows the list in a read-through. Stay on the
two-way door side. Always.
A note on willfulness
Reading this triage is reading something about patents. Reading something about
patents can, in some circumstances, factor into a willfulness analysis down the
road. This is one reason the output is marked as privileged when a lawyer is
using it, and why the non-lawyer output is framed as research to take to
counsel. Do not discuss specific patents surfaced by this triage outside
privileged channels.
Matter context
Matter context. Check ## Matter workspaces in the practice-level CLAUDE.md. If Enabled is ✗ (the default for in-house users), skip the rest of this paragraph — skills use practice-level context and the matter machinery is invisible. If enabled and there is no active matter, ask: "Which matter is this for? Run /ip-legal:matter-workspace switch <slug> or say practice-level." Load the active matter's matter.md for matter-specific context and overrides. Write outputs to the matter folder at ~/.claude/plugins/config/claude-for-legal/ip-legal/matters/<matter-slug>/. Never read another matter's files unless Cross-matter context is on.
Patent FTO matters are particularly common candidates for clean-team or
heightened confidentiality at matter-open. Respect the matter's confidentiality
marking from matter.md.
Load the practice profile first
Before running triage, read ~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md. Pull:
Role from ## Who's using this (lawyer vs. non-lawyer changes the
work-product header and the non-lawyer gate below).
Registered in and enforce where from ## IP practice profile and
## Enforcement posture (useful for defensive-portfolio cross-check and for
jurisdiction defaults).
Patent OC from ## IP practice profile → Outside counsel roster for
the routing step.
Integrations from ## Available integrations — specifically Solve
Intelligence, or any patent-research MCP. Determines what searches
are available.
Decision posture from ## Decision posture on subjective legal calls —
this skill never concludes "does not infringe."
If ~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md contains [PLACEHOLDER] or [Your Company Name], surface this bounce:
I notice you haven't configured your practice profile yet — that's how I tailor posture, jurisdictions, and approval chain to your practice.
Two choices:
Run /ip-legal:cold-start-interview (2 minutes) to configure your profile, then I'll run this tailored to YOUR practice.
Say "provisional" and I'll run this against generic defaults — US jurisdiction, middle risk appetite, lawyer role, no playbook — and tag every output [PROVISIONAL — configure your profile for tailored output] so you can see what I do before committing.
Provisional mode
If the user says "provisional," run the FTO triage normally using these generic defaults: middle risk appetite, lawyer role, US jurisdiction, no playbook (do the full analysis rather than matching against a position list). Tag the reviewer note and every finding block with [PROVISIONAL]. At the end of the output, append:
"That was a generic run against default assumptions. Run /ip-legal:cold-start-interview to get output calibrated to YOUR practice — your playbook, your jurisdiction, your risk appetite. 2 minutes."
Intake
Ask in a single batch:
I'll run an FTO triage. A few questions first:
Product, process, or feature. What's being made, used, offered for
sale, sold, or imported? Describe it plainly — the technical essence, not
the marketing pitch.
Technical detail. Any architectural diagrams, claim-relevant specs, a
public product page, or a spec document you can share? (The more detail,
the more real the triage.)
Jurisdictions. Where will it be made, used, sold, offered for sale,
imported? (Each is a separate infringing act under 35 U.S.C. § 271. I'll
default to the US if you don't specify.)
Known patents. Are there patents already on your radar — a competitor's
portfolio, a known SEP pool, an NPE letter, something an engineer
mentioned?
Timing. How close is this to launch? If it's months out, the triage
is early and design-around is on the table. If it's already shipping,
we're in cover-our-downside mode.
Wait for the answer. If the description is vague ("an AI agent," "a database"),
push once:
Give me the technical essence — what does the thing do, how does it do it,
and what's the piece you think might be novel? Patent claims live at that
level.
Scope — utility patents only
This skill analyzes utility patents. If a patent on the radar has a D,
RE, or PP prefix, flag it and route out, do not claim-chart it:
D (design patent). Different test entirely — ordinary observer under
Egyptian Goddess, Inc. v. Swisa, Inc., 543 F.3d 665 (Fed. Cir. 2008) (en
banc), overall ornamental appearance, no claim chart. Route to the
infringement-triage design patent branch and to design patent counsel.
Design patents are not analyzed in this FTO triage — a design-patent
overlap must be flagged as a separate workstream.
RE (reissue). Treat as a utility patent with added §252 intervening-
rights and recapture-rule flags.
PP (plant patent). Route to plant-patent counsel; out of scope.
Also cross-flag trade dress: if the product's appearance is the risk,
the same facts may be a §43(a) product-configuration claim that requires
secondary meaning (Wal-Mart Stores, Inc. v. Samara Bros., Inc., 529 U.S.
205 (2000)) and non-functionality (TrafFix Devices, Inc. v. Marketing
Displays, Inc., 532 U.S. 23 (2001)). Flag as a parallel track.
Search
What the user has connected
Read ## Available integrations:
Solve Intelligence connected: run a preliminary search across the
technical description. Note the date of the search, the query used, the
jurisdictions covered, and any date window (current in-force patents; recent
published applications).
Patent-research MCP (Google Patents Public Datasets, PatSnap
export): available: use it.
None of the above: explicitly say so. Do not infer patents from model
knowledge and present them as search results.
Fallback when no patent database is connected
Write this exact statement in the output:
No patent database search was run. This triage did not hit Solve
Intelligence Patents, USPTO Patents Full-Text, EPO Espacenet,
Google Patents, PatSnap, or any other patent corpus. A structured search
across the jurisdictions in scope is required before relying on this triage
for any launch decision. The analysis below is limited to patents and
applications the user has named or that come up in the conversation.
Then proceed. The claim-chart-first-pass work below is still valuable — just
label the scope honestly.
Supplementary signals (not a substitute)
If available and the user allows, sweep for non-patent signals that flag a
patent concern:
Competitor patent filings around the product area.
Known NPE targeting of the technology class (e.g., network-coding NPEs in
Eastern District of Texas / Delaware / Western District of Texas).
Standards-essential declarations (IEEE, ETSI, 3GPP) if the product touches
a relevant standard.
Reported litigation in the technology space (CourtListener / RECAP, Unified
Patents, Lex Machina).
Each signal is a reason to look harder, not a patent hit. Mark them as signals
in the output, not as identified patents.
For each relevant patent found or supplied
Capture:
Patent number (with application number if different) and jurisdiction
Title
Assignee and inventors
Priority date and issue date
Expiration date (per USPTO PAIR / PatentCenter / foreign equivalent —
check term adjustments, term extensions, and terminal disclaimers)
Maintenance fee status / in-force status — if a US patent has failed a
3.5/7.5/11.5-year maintenance fee, it's expired and not a bar
Claim count — independent and dependent
Independent claims as issued (and any relevant amended claims from
post-grant proceedings)
Related proceedings — IPRs, PGRs, reexaminations, litigation history,
PTAB outcomes
File wrapper highlights — prosecution disclaimers, amendments that
narrowed the claims, statements about scope
Do not supplement silently. If a search surfaces a patent, attribute the
result. If the user mentioned a patent, say that. Never invent a patent
number, never "fill in" a claim element the file doesn't support, never
imagine an expiration date. If maintenance fee status isn't available, write
"maintenance fee status not verified from search result — confirm in PAIR
before relying on in-force status."
Claim-chart first pass
This is the core of the triage. Pick the patents with the most plausible read
on the product — usually the 2–5 with the closest technical mapping — and walk
each independent claim element-by-element.
For each selected patent, write out one claim chart per independent claim:
Claim element
Does the product practice this?
Basis
"A [preamble phrase]"
[yes / no / possibly / depends on construction]
[one sentence — what in the product maps; what doesn't; what's ambiguous]
"comprising [element 1]"
[yes / no / possibly]
[mapping or gap]
"wherein [element 2]"
[yes / no / possibly]
[mapping or gap]
[continue for every element]
Rules for the chart:
Every element matters. A claim is infringed only if the accused product
practices every element of at least one claim (all-elements rule). Missing one
element literally means no literal infringement on that claim. Do not skip.
Doctrine of equivalents is a separate pass. First chart literal
infringement. Then, for any "no" elements, note whether a DOE read is
plausible (insubstantial differences / function-way-result). Flag DOE
analysis as requiring attorney judgment — prosecution history estoppel and
claim vitiation are common bars and the triage does not adjudicate them.
Claim construction is the attorney's job. Where a term could be
construed narrowly or broadly and the answer changes the infringement read,
flag the term and note both constructions. Do not pick one silently.
Indirect infringement (induced, contributory) and divided infringement
are flags only. Do not attempt a full analysis; note that these may apply and
require patent counsel.
Patent systems differ by jurisdiction. The US claim chart (all-elements rule, doctrine of equivalents, prosecution history estoppel, §284/§289 damages) does not transfer to other systems:
Germany: Utility models (Gebrauchsmuster), the Schneidmesser/Kunststoffrohrteil questions for DOE, bifurcated validity/infringement proceedings.
China: Utility models (shiyong xinxing), CNIPA examination, different claim construction.
Japan: Utility models, JPO examination, a narrower DOE.
Europe (unified patent court): UPC procedure as of 2023.
When non-US jurisdictions are in scope: "This analysis uses the US claim-charting framework. A product manufactured in China and sold in the EU needs CNIPA and EP analysis, not a US claim chart. I can flag the issues a US analysis surfaces, but the infringement and validity calls require [jurisdiction]-specific review."
Decision posture: per the practice profile, this skill never concludes "no
infringement." Either:
"Product practices every element of Claim X as written; attorney review
required before proceeding."
"One or more elements are not clearly present; attorney review required to
assess literal infringement and doctrine of equivalents."
"Claim construction is dispositive on element [Y]; attorney construction
required before proceeding."
Open questions
Every patent surfaced in the triage should produce a list of open questions
that a real FTO study would answer. Examples:
Is the patent enforceable — has the assignee been named, any standing issues,
any inventorship defects, any recorded assignments?
What did the applicant say about term [X] in prosecution, and does that
limit the claim?
Has this claim been the subject of an IPR or reexamination — what did the
PTAB say about scope or validity?
Is there a license already available (standards pool, patent marking, open
patent non-assertion commitment)?
What's the real-world enforcement history of this assignee?
List them plainly.
Recommended next steps
Bucket by what the triage found:
If every element of an independent claim maps to the product (literal read):Stop and get patent counsel. Options typically include formal FTO opinion,
design-around, license, challenge validity (IPR/PGR), or (rarely) proceed at
risk. The choice is a business decision informed by counsel.
If elements cut both ways or claim construction is dispositive:
Full FTO study by registered patent counsel. Do not launch on this triage.
If the patent appears expired, abandoned, or unenforceable: Attorney
confirms the in-force status — the triage does not.
If no patents were identified in the search but no database access
existed: Formal search is the next step, not a launch decision.
Always: flag a willfulness risk. If the triage surfaces a specific
patent, the company now has knowledge of it. Proceeding without further
analysis can support a willfulness finding. Counsel should document the
path forward.

# FTO Triage — First Pass (NOT AN OPINION)**This is not a freedom-to-operate opinion.** A formal FTO opinion requires a
comprehensive search, full claim construction, and element-by-element
infringement analysis by registered patent counsel. Patent infringement is
strict liability; willful infringement triples damages. A "no obvious blocking

is clear. A registered patent attorney or agent evaluates before anyone relies
on this for a product decision.

## Willfulness note
This triage surfaces specific patents. Proceeding with the product without
further counsel review after this knowledge can support a willfulness finding
and enhanced damages under § 284. The path forward should be documented by
patent counsel; the business decision to launch, design around, or license is
informed by a formal FTO opinion and counsel's judgment, not by this triage.
## Citation verification
Every patent number, claim quote, date, and prosecution fact in this memo must
be verified against the authoritative source (USPTO PatentCenter / PAIR, EPO
register, national equivalent) before relying on it. Claim quotes are the
most common error site — a single word changes the analysis. Do not cite a
result you cannot open.
Non-lawyer gate
Before issuing the output, read ## Who's using this. If the Role is Non-lawyer:
This output is a research triage, not legal advice. Launching, continuing to
sell, or investing in this product based on this triage alone has legal
consequences — including strict liability for patent infringement, with
enhanced damages for willfulness. Patent counsel needs to evaluate before
you move.
Here's a brief to bring to an attorney — it'll cut the time the conversation
takes:
[Generate a 1-page summary: the product description, the jurisdictions in
scope, the search run (and what wasn't searched), the patents surfaced and
the claim-chart-first-pass reads, the open questions, and the three
questions to ask the attorney.]
If you need to find a licensed attorney, solicitor, barrister, or other authorised legal professional in your jurisdiction: for US patent work, a registered patent attorney or patent agent is required (not every lawyer is registered — the USPTO
Office of Enrollment and Discipline maintains a directory). For other jurisdictions, use the relevant patent office register (EPO, UK IPO, etc.). Your professional regulator's referral service is a starting point (state bar in the US, SRA/Bar Standards Board in England & Wales, Law Society in Scotland/NI/Ireland/Canada/Australia, or your jurisdiction's equivalent); specifically ask for registered
patent counsel.
Deliver the full triage memo alongside the brief. Do not withhold the analysis.
Flag that the triage itself is a privileged research document and should not
be forwarded to non-attorney third parties.
Output location
If matter workspaces are enabled and a matter is active, write the output to
~/.claude/plugins/config/claude-for-legal/ip-legal/matters/<matter-slug>/outputs/fto-triage-<subject-slug>-YYYY-MM-DD.md.
Otherwise write to
~/.claude/plugins/config/claude-for-legal/ip-legal/outputs/fto-triage-<subject-slug>-YYYY-MM-DD.md
and surface the path.
Append a one-line entry to the matter's history.md if a matter is active.
Close with the next-steps decision tree
End with the next-steps decision tree per CLAUDE.md ## Outputs. Customize the options to what this skill just produced — the five default branches (draft the X, escalate, get more facts, watch and wait, something else) are a starting point, not a lock-in. The tree is the output; the lawyer picks.
What this skill does not do
Issue an FTO opinion. Ever. The loudest guardrail in the plugin.
Construe claims. Where construction is dispositive, it flags the term and
both plausible constructions. It does not pick one.
Adjudicate validity. It may note known PTAB proceedings; it does not
opine on novelty, obviousness, § 112, § 101, or enablement.
Draft patent claims. This plugin does not go there; route to prosecution
counsel.
Assess damages exposure. Damages modeling is an expert's job.
Handle trade-secret or trademark analysis — use /ip-legal:infringement-triage
with the right mode.
Quote outputs to counterparties or non-privileged audiences. This is a
privileged research document.
Tone
Technically precise. Element-by-element. Every flag is specific to a claim
element or a known patent. No hedging prose in the body — the guardrails at
the top and bottom do the scope work, and the analysis does the analysis. The
reader should leave knowing what the triage looked at, what it didn't, and
what the next step is.
