Field of Use Restriction Clause
Draft an enforceable field-of-use restriction clause that limits licensee exploitation to a defined scope while preserving licensor rights.
Prerequisites
Gather before drafting:
- Licensed IP — patent numbers, technology descriptions, product specs, trade secret scope
- Existing agreements — prior licenses, third-party rights, commitments affecting grantable scope
- Business parameters — field boundaries (industry, geography, customer type, application method), exclusivity, sublicensing intent
- Party information — licensor/licensee details, affiliates, related entities
Workflow
1. Define Key Terms
| Term |
Drafting Notes |
| Licensed Technology |
Draw from patent claims, technical specs, product docs |
| Field of Use |
Delineate by industry sector, geographic market, customer type, application method, or combination |
| Permitted Applications |
Affirmative list of authorized uses |
| Restricted Fields |
Explicit exclusions from the grant |
| Improvements / Derivatives |
Whether modifications remain subject to restriction |
Cross-reference definitions with industry-standard terminology. Pull technical language from uploaded patent claims and specs.
2. Draft Grant of License
Grant clause must address:
- Exclusivity status within the permitted field
- Sublicensing rights and conditions
- Specific patent numbers; whether continuations/improvements included
- Know-how/trade secret scope and disclosure restrictions
- Term, renewal conditions, milestone-based field expansion
- Prior licenses or third-party rights carve-outs
Reserve all rights not expressly granted.
3. Specify Restrictions & Prohibited Activities
| Prohibition |
Language Target |
| Direct use outside field |
"shall not, directly or indirectly, use Licensed Technology for any purpose outside the Field of Use" |
| Sublicense/assignment to restricted fields |
Prohibit transfer of rights into restricted areas |
| Circumvention via affiliates/third parties |
Bar supplying components to parties who will use in restricted fields |
| Derivative works in restricted fields |
Modifications remain subject to field restriction |
Affirmative obligations: flow-down to sublicenses, product marking with notices, internal compliance controls.
4. Include Monitoring & Audit Rights
- Audit right — licensor may audit books, records, operations for field compliance
- Notice period — typically 15–30 days
- Records retention — sales by application/market, customer lists, product descriptions
- Periodic reporting — tie compliance reporting to royalty calculations where applicable
- Cooperation — licensee must provide access and information
5. Define Breach Remedies
| Breach Severity |
Consequence |
| Material / willful |
Immediate termination, no cure period |
| Minor / inadvertent |
Cure period (typically 30 days), auto-termination if unremedied |
Monetary: liquidated damages (reasonable, not punitive), enhanced royalties on unauthorized uses, disgorgement of restricted-field profits.
Equitable: injunctive relief preserved; post-termination cease-use, return/destroy materials, assign IP from unauthorized use. Confidentiality and field restrictions survive termination.
6. Set Governing Law & Dispute Resolution
- Choice of law — jurisdiction with developed licensing case law (licensor HQ, technology origin, or primary licensee operations)
- Dispute mechanism — litigation, arbitration (technical panel for complex IP), or hybrid
- Expedited relief — preserve court access for TROs/preliminary injunctions even under arbitration
- Fees — each party bears own unless position substantially unjustified
Pitfalls & Checks
- Define field boundaries using multiple parameters (industry + application + geography) to reduce ambiguity
- Ensure liquidated damages are calibrated to anticipated harm, not punitive
- Verify all factual details (patent numbers, specs) match uploaded source documents exactly
- Flag jurisdiction-specific enforceability concerns — U.S. antitrust/competition law may limit overly broad restrictions (Princo Corp. v. ITC, 616 F.3d 1318 (Fed. Cir. 2010) [VERIFY])
- Adapt all language to specific deal terms; do not copy template language verbatim
- Mark clause for attorney review — field-of-use disputes are heavily fact-dependent
