Right to use the technologyNo, unless a separate evaluation agreement or license is also in placeYes, within the scope negotiated (field of use, territory, exclusivity)
Typical durationA few months to about a year, sometimes longer with milestonesCan run for the life of the underlying patent or longer for know-how/trade secrets
Typical fee structureOption fee plus reimbursement of patent prosecution costs during the option periodUpfront fee, running royalties, milestone payments, and/or equity, depending on terms
ExclusivityExclusivity applies to negotiation only -- the institution cannot shop the technology to others during the option periodExclusivity (if any) applies to the actual commercialization rights granted, defined by field of use and territory
When it is usedEarly-stage companies, often pre-financing, that need time before committing to full license negotiationOnce the parties are ready to commit to defined commercialization terms

Common questions

Common questions about Option Agreement vs License Agreement

Can an option agreement include any right to use the technology?

+

Not by default. An option agreement’s core grant is negotiation exclusivity, not use rights. If a prospective licensee also needs to test or benchmark the technology, that typically requires a separate evaluation agreement.

Is an option agreement the same as a right of first negotiation or first refusal?

+

Related but not identical. A right of first negotiation typically requires the institution to negotiate with the option holder first, without necessarily foreclosing negotiation with a third party if those talks fail. A fully exclusive option forecloses negotiation with anyone else during the option period. The exact scope depends on the specific agreement’s language.

Do institutions charge for an option agreement?

+

Most option agreements include an option fee plus reimbursement of the institution’s patent prosecution costs during the option period, since the institution is giving up the ability to shop the technology to other prospective licensees for that duration.

Why would a startup want an option instead of just negotiating the license directly?

+

Speed and cost. An option agreement is a shorter, cheaper document to negotiate than a full license, and it lets an early-stage company secure its IP position — something investors typically want to see before committing funding — before spending the time and legal cost a full license negotiation requires.
