Review the IP clauses in an agreement — assignment, ownership, license grants, warranties, indemnities. Use when reviewing IP terms in employment, consulting, SOW, vendor, or licensing agreements, when asked to check the assignment language or license scope, or when an agreement with IP provisions is pasted or attached.
Reviews the IP clauses in an agreement against the practice profile in ~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md. Flags assignment gaps, ownership ambiguity, license-scope issues, and IP warranty/indemnity problems. Produces a memo with per-clause findings, prioritized by risk, with suggested redline language where appropriate.
Instructions
Load ~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md. If placeholders present, stop and prompt: "Run /ip-legal:cold-start-interview first — I need to learn your practice profile before I can review IP clauses against it."
Get the agreement: From file path, Drive link, or pasted text. If none provided, ask.
Follow the workflow below. In particular:
Establish the agreement type and which side the company is on for IP (granting / receiving / both). The side question is per-document, not a one-time setup answer.
Run the assignment gap check first if the agreement is an employment, consulting, SOW, or work-for-hire document.
Produce per-clause findings prioritized by risk.
Check cross-clause consistency, not just clause-by-clause.
Output the memo per the template below — work-product header first, bottom line, assignment gap check, clauses by severity, consistency flags, jurisdiction note, approval routing.
Respect the decision posture. When a clause could be read to allocate IP either way, flag for attorney review and surface the factors cutting both ways. Never silently decide a subjective allocation question.
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 . Never read another matter's files unless is .
Read the IP clauses in an agreement and tell the lawyer what each one does, how it deviates from market or from the team's standard position, what the risk is, and — where appropriate — the specific redline to propose. The goal is a memo the lawyer can act on in one pass.
The highest-stakes clauses in most agreements are IP ownership and assignment. They are hard to fix later. A failure to get a clean assignment on an employment or consulting agreement surfaces in M&A diligence, in financing, and in litigation, sometimes years after the agreement was signed. If assignment language is weak or missing in a document that should have it, flag it loudly at the top of the memo — not buried as one line item among many.
Precondition: load the practice profile
Before reading the agreement, read ~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md. If it is missing or still contains placeholders, stop and run /ip-legal:cold-start-interview. The practice profile tells you:
The jurisdiction footprint — which affects whether moral rights waivers are enforceable, whether work-for-hire applies, whether implied assignment fills a gap, how broad license grants can be
Who approves deviations and at what severity
The work-product header to prepend to outputs
Workflow
Step 1: Orient
Read the whole agreement once, fast. Answer:
Question
Answer
What kind of agreement is this?
Employment / consulting or SOW / vendor MSA / in-license / out-license / collaboration or JDA / settlement / acquisition or asset purchase / other
Which side are we on for IP?
Granting rights or receiving them / assigning IP or acquiring it / licensor or licensee
Who is the counterparty?
Name, and sophistication — individual, startup, BigCo
Is there consideration flowing for the IP specifically?
What does it say — and does our practice profile flag that jurisdiction as escalate/never?
The side question is per-document, not a one-time setup answer. An in-house counsel reviewing an employment agreement is on the "receiving" side; reviewing an out-license the same day, on the "granting" side. The posture inverts.
If the side is ambiguous (a collaboration agreement where both parties contribute and both receive rights, a reseller agreement with flow-through IP), ask:
Which side is [company] on for this agreement's IP? Granting rights, receiving rights, or both? If both, I'll review each direction separately.
Step 2: Assignment gap check (highest priority)
If the agreement is an employment agreement, consulting agreement, SOW, work-for-hire contract, or anything else where the company should be receiving an assignment of the counterparty's IP in work product — check the assignment language first.
Look for:
Present-tense assignment ("hereby assigns" or "hereby irrevocably assigns and agrees to assign"). A bare "agrees to assign" is a promise to assign, not an assignment, and can require a second document to perfect.
Scope — does it cover all IP created in the course of engagement, or only IP related to the company's business, or only IP created using company resources? Narrow scope is a gap if work product is expected to range broadly.
Moral rights waiver (for jurisdictions that recognize moral rights — EU member states, Canada, many others — the US recognizes a narrow version for visual art). If the agreement is governed by or has counterparties in a moral-rights jurisdiction, a waiver or non-assertion covenant matters.
Further assurances clause — counterparty agrees to sign whatever else is needed to perfect the assignment later.
Pre-existing IP carveout — what does the counterparty exclude from the assignment, and is that list specific or open-ended?
If any of the above is missing or weak, flag at the top of the memo with a 🔴 or 🟠 severity and a specific redline.
## ⚠️ ASSIGNMENT GAP**Section [X]** assigns IP in the work product, but: [specific issue — e.g.,
"'agrees to assign' rather than 'hereby assigns,'" or "no moral rights waiver
and governing law is France," or "no carveout list is provided and the
counterparty has pre-existing platform IP"].
**Risk:** This is the kind of gap that surfaces in M&A diligence years later.
The counterparty (or a successor) may have residual rights in work product we
thought we owned.
**Proposed redline:**> "[specific replacement language]"**Escalation:** Per `~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md`, assignment-scope gaps escalate to [approver].
Can the assignment convey AI-generated content?Thaler v. Perlmutter and the Copyright Office's 2023 AI registration guidance suggest that AI-generated works without any human authorship may not be copyrightable, though the boundaries remain unclear and this area is evolving. If the contractor uses AI for substantial portions of the deliverables, the copyright status of those portions is uncertain — and an assignment clause can only convey rights that exist.
Check: does the agreement have an AI-use disclosure obligation? A representation about the role of AI in the deliverables? A mechanism to identify which portions are AI-assisted vs. human-authored?
If absent and AI-assisted creation is foreseeable (consulting, development, content creation, design): 🟠 High. "The assignment clause is well-drafted but there's no AI-use disclosure. The copyright status of AI-generated content is unsettled, and without a disclosure obligation you won't know which portions are affected. Add an AI-use representation and a disclosure obligation." [review — copyright status of AI-generated works is an evolving area; verify against current Copyright Office guidance and case law]
AI-assisted inventorship. A patent filed with incorrect inventorship is unenforceable. If a consultant uses AI tools that contribute to an inventive concept, the inventorship question is unsettled and the patent is at risk. For any agreement with patent assignment provisions covering potentially patentable work product:
Check: does the agreement have an AI-use representation? A process for determining inventorship where AI contributed? A disclosure obligation about AI use in the inventive process?
If absent: flag. "Patent assignment without an AI-use representation. If AI tools contributed to the inventive concept, inventorship determination is complicated and an incorrectly-attributed patent is unenforceable. Add an AI-use representation and inventorship protocol."
Step 3: Clause-by-clause review
For every IP-relevant clause, produce a block. The clauses to look for:
Assignment / work-for-hire — who owns what's created under the agreement
Ownership of deliverables — distinct from assignment; often states the output of the engagement
Improvements and derivatives — who owns improvements to pre-existing IP, who owns derivative works
Background IP vs. foreground IP — does the agreement define pre-existing IP and newly-created IP separately, and license the background IP to the extent needed?
License grants — scope, exclusivity, territory, field of use, sublicensability, term, termination triggers, royalty or fee structure
IP warranties — non-infringement of third-party rights, authority to grant, original work
Open source representations — representations about what OSS is and is not embedded in deliverables
Trademark use — any grant or restriction on use of the other party's marks; brand guidelines; quality control for licensor
Confidentiality / trade secrets — treatment of trade secret material, reasonable measures, return or destruction, post-term obligations
For each clause present, produce:
### [Section X.X]: [Clause name]**What it says:** [plain-English summary, one or two sentences]
**What's market (for this agreement type, this side, this jurisdiction):**
[brief reference point]
**Risk:** 🔴 Critical | 🟠 High | 🟡 Medium | 🟢 Low
**Why it matters:** [one or two sentences — what goes wrong for the business
if this stays as-is]
**Proposed redline (if needed):**> "[specific replacement language]"**Decision call:** [If uncertain whether the clause achieves the intended IP
allocation, flag for attorney review and state the factors cutting both
ways. Do not silently decide a subjective allocation question.]
Severity calibration:
Level
Means
🔴 Critical
Don't sign without fixing. Assignment gap in a document that should have one. Unlimited license where a narrow one was intended. Exclusive grant where non-exclusive was intended.
🟠 High
Strongly push; escalate if they won't move. Ambiguous scope, missing moral rights waiver in a moral rights jurisdiction, missing further assurances, narrow indemnity.
🟡 Medium
Push in first round; accept if it's the last open item. Cosmetic but imprecise language, survival periods shorter than standard.
🟢 Low
Note it, don't spend capital. A stylistic deviation that doesn't change the allocation.
Step 4: Cross-clause consistency
IP clauses fail as a system. Check:
Does the license grant match the scope of what's being licensed? (A license to "use" the deliverable is narrower than a license to "use, modify, and create derivative works.")
Do the warranties cover everything the grant covers? (A warranty of non-infringement limited to patents, in a license that also covers copyrights and trade secrets, leaves gaps.)
Does the indemnity cover what the warranty promises? (A warranty without indemnity is a promise without a remedy.)
Does termination pull the license back? (Or does a paid-up license survive termination? Either is defensible — the question is whether it matches intent.)
Is the IP allocation between this agreement and any related SOW, order form, or related side letter consistent? Flag conflicts.
Step 5: Jurisdiction note
IP rules are jurisdiction-specific in ways that change the outcome. Flag if the agreement implicates any of these:
Moral rights — EU member states, Canada, much of the civil-law world recognize moral rights (paternity, integrity) that may not be fully assignable or waivable. US recognition is narrow (VARA, for visual art).
Work-for-hire — US doctrine is statutory (17 U.S.C. § 101) and only applies to enumerated categories for independent contractors. UK implies assignment in the employment context but not always for contractors. Civil-law jurisdictions handle this differently again.
Implied license — common-law jurisdictions may read in an implied license where the written grant is silent. Civil-law jurisdictions tend not to.
Patent indemnity exclusions — combinations, modifications, and user supply of accused features are standard US exclusions; the interaction with EU patent and UPC is still developing.
State what jurisdiction the agreement is governed by, and whether the practice profile flags that jurisdiction as standard, escalate, or never.
Redline granularity
Edit at the smallest possible granularity. A redline is a negotiation artifact, not a rewrite. Wholesale clause replacement signals "we threw out your drafting" — it's aggressive, it forces the counterparty to re-read the whole clause, and it discards the parts of their drafting that were fine. Surgical redlines — strike a word, insert a phrase, restructure a subclause — signal "we have specific asks" and are faster to read, understand, and accept.
Default to the smallest edit that achieves the playbook position:
Replace a word before a phrase. ("twelve (12)" → "twenty-four (24)")
Replace a phrase before a sentence. ("paid by the Buyer" → "paid and payable by the Buyer")
Restructure a subclause before replacing the sentence. (Add "(a)" and "(b)" to split a compound condition.)
Replace a sentence before replacing the clause.
Only replace a whole clause when the counterparty's version is so far from your position that surgical edits would be harder to read than a fresh draft — and when you do, say so in the transmittal: "We've replaced §8.2 rather than marking it up because the changes were extensive. Happy to walk you through the delta."
When in doubt, smaller. A client who receives a surgical redline trusts that you read carefully. A client who receives a wholesale replacement wonders whether you read at all.
Step 6: Assemble the memo
Prepend the work-product header from ~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md → ## Outputs (it differs by user role — see ## Who's using this).
This memo and the underlying agreement may be privileged, confidential, or both. The output inherits that status from the source. Distribute only within the privilege circle; mark and store it where privileged materials live; strip the work-product header before any external delivery.
No silent supplement. If a research query to the configured legal research tool returns few or no results for a rule the memo needs (enforceability of a moral rights waiver in a given jurisdiction, scope of an implied license, standard for an IP warranty survival period), report what was found and stop. Do NOT fill the gap from web search or model knowledge without asking. Say: "The search returned [N] results from [tool]. Coverage appears thin for [rule / jurisdiction]. Options: (1) broaden the search query, (2) try a different research tool, (3) search the web — results will be tagged [web search — verify] and should be checked against a primary source before relying, or (4) flag as unverified and stop. Which would you like?" A lawyer decides whether to accept lower-confidence sources.
Source attribution. Where the memo cites a statute, regulation, case, or treatise, tag the citation: [Westlaw], [statute / regulator site], or the MCP tool name for citations retrieved from a legal research connector; [web search — verify] for web-search citations; [model knowledge — verify] for citations recalled from training data; [user provided] for citations from the counterparty draft or house files. Citations tagged verify carry higher fabrication risk and should be checked first. Never strip or collapse the tags.

Decision posture
When a clause could be read to allocate IP either way, or when it is unclear whether the drafter's chosen words achieve the stated intent, flag it for attorney review and surface the factors cutting both ways. Do not silently decide a subjective allocation question. An unresolved IP allocation that gets signed is a one-way door — the error surfaces in diligence, financing, or litigation. Flagging an ambiguous clause that turns out to be fine is a two-way door.
