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
