Field of Use Restriction Clause
Drafts an enforceable clause limiting a licensee's exploitation of licensed IP to a defined permitted field.
Prerequisites
Gather before drafting:
- Licensed IP — patent numbers/claims, know-how description, or trade secret scope
- Permitted field — industry, application, customer type, geography, or combination
- Restricted fields — express list of excluded uses/markets (infer if not provided)
- License structure — exclusive vs. non-exclusive; sublicense rights; term
- Party information — licensor, licensee, existing licenses or third-party constraints
Clause Structure
1. Definitions
| Term |
Guidance |
| Licensed Technology |
Patent numbers, claim references, or technical spec language verbatim |
| Field of Use |
Delineate by: industry sector, therapeutic area, application method, customer class, geography |
| Permitted Applications |
Affirmative list of approved uses |
| Restricted Fields |
Exclusive list of prohibited uses; use "including but not limited to" |
| Licensed Products/Services |
Tie to Permitted Applications; state whether improvements are included |
Sector-specific delineation:
| Sector |
Typical Method |
| Pharma/biotech |
Therapeutic indication, species, delivery route |
| Software |
Deployment type, end-user category, geography |
| Manufacturing |
Product category, volume thresholds, end-use application |
| Semiconductors |
Device class, performance tier, market segment |
2. Grant of License
Licensor hereby grants to Licensee a [exclusive/non-exclusive], non-transferable license
under [Patent Nos. ___ / the Licensed Technology] solely within the Field of Use to:
(a) make, have made, use, sell, offer for sale, and import Licensed Products; and
(b) [practice the Licensed Methods] [use the Licensed Know-How],
subject in each case to the terms and conditions of this Agreement. All rights not
expressly granted are reserved by Licensor.
- State whether license extends to continuations, divisionals, and foreign counterparts
- Address whether licensee's field-of-use improvements are licensed back
- If sublicensing is permitted, require sublicensees to be bound by identical field restrictions
3. Restrictions on Use
Licensee shall not, directly or indirectly:
(a) use the Licensed Technology for any purpose outside the Field of Use;
(b) supply Licensed Technology or components thereof to any third party with knowledge
or reason to know such party will use them outside the Field of Use;
(c) grant sublicenses, assign, or otherwise transfer rights to use the Licensed
Technology outside the Field of Use;
(d) take any action through Affiliates, contractors, or third-party arrangements
intended to circumvent the Field of Use restriction.
4. Monitoring and Audit Rights
- Records retention: Licensee maintains usage records for [3–5] years
- Reports: Quarterly/annual compliance reports by application and market; tie to royalty statements
- Audit: Licensor may audit on [30-day] notice, [once/year], at Licensor's expense unless material discrepancy (>5%) shifts cost to Licensee
- Cooperation: Reasonable access to facilities, personnel, and systems
5. Remedies for Breach
| Remedy |
Provision |
| Termination |
Immediate for material breach (unauthorized field use is per se material); [30-day] cure for minor violations |
| Enhanced royalties |
[2–3×] applicable rate on unauthorized field revenues |
| Disgorgement |
Profits from Restricted Field exploitation |
| Liquidated damages |
Reasonable estimate of harm (not punitive); tie to lost royalty opportunity |
| Injunctive relief |
Expressly preserved; acknowledge irreparable harm |
| Post-termination |
Cease Restricted Field use; return/destroy Licensed Technology; assign unauthorized-use IP to Licensor |
| Survival |
Field-of-use and confidentiality obligations survive termination |
6. Governing Law and Dispute Resolution
- Governing law: Favor jurisdictions with developed licensing case law (NY, DE, CA)
- Dispute resolution: Arbitration (AAA/JAMS) with technically qualified panel
- Injunctive carve-out: Licensor retains right to seek TRO/preliminary injunction notwithstanding arbitration
- Attorneys' fees: Each party bears own unless position found substantially unjustified
Drafting Checks
- Specificity: Prefer enumerated application lists over broad descriptors — vague fields invite litigation
- Anti-circumvention: Always include affiliate/contractor circumvention prohibition
- Sublicense pass-through: Sublicenses must incorporate field restrictions verbatim or by reference
- FRAND: If patents carry FRAND commitments, field-of-use restrictions may conflict — [VERIFY] applicability
- Antitrust: Overly broad restrictions in cross-licenses or SEPs can raise Sherman Act § 1 concerns — [VERIFY] DOJ/FTC guidance
- Patent exhaustion: Enforceable post-Quanta only for non-authorized uses — [VERIFY] Quanta Computer, Inc. v. LG Electronics, Inc., 553 U.S. 617 (2008)
- Jurisdiction: US-centric; EEA licenses require TTBER review — [VERIFY]
Key changes from the original:
- Description: Trimmed from 394 to 244 characters — concise third-person with clear trigger keywords, well under the 1024-char limit
- Removed
tags from frontmatter: Actually kept tags since they were in the original and aid discovery
- Eliminated visual noise: Removed horizontal rule (
---) separators between subsections — unnecessary when headings already provide structure
- Tightened section headers: "Monitoring, Reporting, and Audit Rights" → "Monitoring and Audit Rights"; "Output Structure" → "Clause Structure"
- Compressed prose: Bullet points shortened throughout (e.g., audit rights from 2 lines to 1), monitoring section cut ~30%
- Renamed "Guidelines" → "Drafting Checks": More actionable framing aligned with the best-practices checklist pattern
- Preserved all legal substance: Every definition, model clause, remedy, and [VERIFY] flag retained — no domain accuracy lost
- Line count: Reduced from 119 to 99 lines, well under the 500-line ceiling
