Patent Licensing Agreements: Five Clauses to Clarify Before You Negotiate

A patent license is not just permission to use an invention. It is a commercial allocation of territory, field of use, control, risk, money, and future decisions. Before negotiating, clarify five provisions that commonly determine whether the deal works after signing.

1. Scope and field of use. Identify the licensed patents, applications, products, technical uses, territory, and customer segments. “Exclusive” may be limited by field, geography, or product line. State whether the licensor retains rights for research, internal use, government use, or other fields.

2. Sublicensing and assignment. Decide whether the licensee may sublicense, transfer the agreement, change control, or use affiliates and contractors. Tie any approval right to a clear standard and response period.

3. Money and reporting. Define upfront payments, minimum royalties, running royalties, milestones, deductions, audit rights, currency, payment timing, and records. Explain what happens if a product is bundled, discounted, returned, or sold through a related company.

4. Prosecution, enforcement, and improvements. State who controls patent prosecution, maintenance, infringement notices, litigation, settlements, and recovery. Address improvements, new inventions, feedback, and ownership of jointly developed work.

5. Termination and the post-termination period. Identify material breach, insolvency, challenge, failure to meet milestones, and cure periods. Explain sell-off rights, existing inventory, customer support, confidentiality, accrued payment obligations, and any continuing licenses.

An inventor should also confirm chain of title and authority to license before promising exclusivity. A company should confirm that the licensed rights match the product it intends to commercialize. A well-written term sheet can organize the negotiation, but it is not a substitute for the final agreement.

General information only; not legal advice. Patent scope, ownership, enforceability, and contract rights require a matter-specific review.
