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
