Four Provisions Every Patent Licensing Agreement Must Contain

Authored by Babak Akhlaghi on June 21, 2026.  You spent years building something real. You fought through prosecution. You finally have the patent in hand.

Then someone wants to license it.

That feels like validation. It feels like the finish line.

But one poorly drafted clause can quietly undo everything you built, not through litigation, not through a bad ruling, but through a contract that wasn’t structured right.

The Federal Circuit’s 2026 decision in A.L.M. Holding Co. v. Zydex Industries shows exactly what happens when you get it right. The patent owners licensed nearly all commercial rights, worldwide, exclusive, royalty-bearing, but they retained four critical provisions that preserved their enforcement power.

Here’s what you need in every licensing agreement.

1. The Grant Clause — The Most Important Provision

The grant clause is the heart of any patent licensing agreement. It specifies exactly which rights you’re assigning: make, use, sell, import, enforce.

Every patent comes with these exclusionary rights. You can assign them selectively. You can assign the right to sell but not manufacture. You can limit by territory. You can restrict by field of use.

The danger is signing away more than you intended.

Verify the rights granted match your commercial intent. Scope, territory, exclusivity, all must be explicit. Clarity in the grant clause protects both parties and preserves your ability to license to others or maintain competitive advantages in adjacent markets.

(This is where strategic patent planning from the start pays off.)

2. Exclusivity Mechanics with Performance Milestones

If your license is exclusive, it should include minimum royalty thresholds or performance milestones.

A licensee who sits on your patent generates no royalties and blocks you from commercializing through other channels. One 20-year study found that 60% of licensing agreements had underreported sales, typically from licensees omitting products or uses from royalty calculations.

Performance milestones give you recourse without litigation.

Structure it this way: if the licensee fails to meet minimum annual royalties or launch deadlines, the exclusive license becomes non-exclusive. Or it terminates entirely.

In A.L.M. v. Zydex, the agreement included exactly this provision. If Ingevity failed to pay guaranteed minimum royalty amounts, the license would convert to non-exclusive. That gave the patent owners leverage without going to court.

3. The Right to Sue — Retain It

You want to maintain the right to sue third-party infringers. Jointly or exclusively.

If you grant it jointly, the agreement must specify: what happens when the licensee doesn’t want to sue, who controls the litigation, who collects the damages.

You should be able to proceed independently if the licensee steps back.

The licensee’s incentives might diverge from yours. They might have a business relationship with the infringer. They might not want the legal exposure. They might just not want to spend the money.

In A.L.M. v. Zydex, the licensing agreement provided for shared control of infringement actions and an equal split of any resulting recoveries and costs. But if either party elected not to pursue infringement, the other party could bring suit independently and retain all damages.

The Federal Circuit held that this structure, combined with royalty interests and sublicensing controls, meant the patent owners retained “a non-illusory exclusionary interest” sufficient for constitutional standing. The court distinguished cases where the right to sue was illusory because the licensee could moot any lawsuit by granting a royalty-free sublicense to the accused infringer.

4. Sublicensing and Assignment Controls

Any sublicense or assignment must require your approval as the patent owner.

Royalties from sublicensees must flow to you as if generated by the licensee. Sublicensees must be bound by the terms of the original agreement.

In A.L.M. v. Zydex, the agreement required that sublicensing terms be subject to the patent owners’ prior review and approval, not to be unreasonably withheld. Sales made by a sublicensee had to be reported and royalty paid to the patent owners as if Ingevity had made the sale. The obligations in the agreement were binding on any sublicensee as if it were a party to the contract.

This provision was critical to the court’s finding that the owners maintained sufficient exclusionary rights.

Without it, the licensee could authorize an accused infringer’s practice of the patents without your consent and free of your royalty interests. You’d watch your market erode and have no recourse.

One Sentence to Carry With You

Before you sign, imagine the day your interests diverge from the licensee and make sure the contract gives you a remedy when that happens.

That’s not a legal exercise. That’s an act of honesty with yourself about what this relationship might actually become.

Run the agreement by a seasoned patent attorney with licensing experience. These agreements are not boilerplate. A single provision can give away rights you didn’t intend or leave substantial revenue on the table.

You worked too hard to protect your invention at the start. Don’t lose it at the licensing stage.
