Field of Use Restriction Clause

Drafts a narrow, enforceable licensing clause that limits exploitation rights to a defined field while preserving licensor control outside that field. U.S.-focused; cross-border enforcement may require localization. [VERIFY]

Prerequisites

Before drafting, confirm:

1. Grant model defined — IP type, exclusive/non-exclusive, term, royalty logic, territory.
2. Portfolio data collected — patent IDs, software modules/versions, know-how, related IP.
3. Business boundaries set — industries, customer types, channels, geographies, prohibited markets.
4. Source documents available — draft agreement, SOW, schedules, prior licenses.
5. Enforcement preferences — audit cadence, reporting format, cure policy, remedy priorities.
6. Jurisdiction selected — governing law, venue/forum, injunctive relief requirements.

Quick Start

Gather inputs across five dimensions, then assemble clause sections in order:

Input	Capture	Drives
Field scope	Industry, use case, geography, customer type, channel	Field of Use definition and negative examples
IP scope	Patent IDs, software versions, process assets	Covered subject-matter precision
Commercial rights	Grant type, exclusivity, sublicensing	Reservation-of-rights language
Compliance controls	Reporting cadence, records, audit access	Audit and reporting mechanics
Enforcement posture	Cure tolerance, injunction needs, termination triggers	Remedies and transition provisions

Clause Assembly

Draft sections in this order:

1. Definitions — Licensed Property, Field of Use, Permitted Applications, Restricted Fields, plus technology-specific terms from patents/specs.
2. Grant — Confer rights only within Field of Use; reserve all rights outside; tie term/milestones to any scope evolution.
3. Sublicense/assignment — Scope limits, mandatory field-of-use flow-down notices, licensor approval where required.
