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:

1. Licensed IP — patent numbers, technology descriptions, product specs, trade secret scope
2. Existing agreements — prior licenses, third-party rights, commitments affecting grantable scope
3. Business parameters — field boundaries (industry, geography, customer type, application method), exclusivity, sublicensing intent
4. 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
