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:

1. Licensed IP — patent numbers/claims, know-how description, or trade secret scope
2. Permitted field — industry, application, customer type, geography, or combination
3. Restricted fields — express list of excluded uses/markets (infer if not provided)
4. License structure — exclusive vs. non-exclusive; sublicense rights; term
5. 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
