/ip clause review
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
1. 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."
2. Get the agreement: From file path, Drive link, or pasted text. If none provided, ask.
3. 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.
Note jurisdiction implications (moral rights, work for hire, implied license, patent indemnity).
4. 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.
5. 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.
Examples
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 .
Purpose
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? Salary, fee, royalty, upfront payment, equity, none
Governing law and venue 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.
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
IP indemnities — scope, cap, procedure, exclusions (user modifications, combinations, unauthorized use)
Moral rights waiver — jurisdiction dependent
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:
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.
