Background

IBM and electric-vehicle company Mullen Technologies signed a joint development and technology license agreement concerning lithium battery technology and a separate trademark license. Mullen was to pay $4 million for IBM background materials and know-how and $500,000 for a worldwide, nonexclusive trademark license.

Mullen made neither payment. It asserted that it learned IBM’s lithium-air battery was about a decade from commercialization rather than two years away and maintained that IBM had not performed its own technology-delivery obligations. IBM sued and obtained summary judgment on both contracts.

After an inquest, Supreme Court entered $4.5 million in principal damages and a total judgment exceeding $5.6 million with interest and costs. Mullen appealed, challenging IBM’s performance proof and seeking discovery on fraudulent inducement.

The procedural posture limits the ruling but does not diminish its operational significance. The appellate court decided whether the existing record permitted dismissal or judgment as a matter of law; unresolved facts and ultimate remedies remain for the trial court where applicable. New York practitioners should translate the holding into contemporaneous documentation rather than wait for litigation: preserve the governing agreements, notices, technical records, agency materials, communications, and evidence connecting each legal element to the requested relief.

The opinion also illustrates that labels do not control. Courts examine the actual contractual language, statutory structure, evidentiary burden, and conduct of each party. Businesses and counsel should therefore test the strongest anticipated defense early, identify which party bears the initial burden, and ensure that affidavits and records address the specific theory rather than offer generalized conclusions.

At the next stage, the parties will also need to separate what the appellate holding conclusively establishes from what remains open. A ruling that a claim survives does not prove liability, while reversal of summary judgment does not necessarily erase an undisputed component of damages or a distinct claim under another agreement. Litigation plans should map each remaining element, available witness, expert issue, and measure of damages. Transactional lawyers can use the same map prospectively by assigning responsibility, specifying notice and recordkeeping procedures, and making performance or compliance milestones objectively verifiable. That discipline reduces both operational uncertainty and the risk that an otherwise strong position fails because the necessary proof appears too late.

The Court’s Holding

The Second Department reversed the judgment in part. IBM established breach of the trademark agreement: it granted the licensed mark and Mullen failed to pay the agreed $500,000 royalty. That amount was recoverable as general contract damages.

IBM did not establish entitlement to summary judgment on the $4 million joint-development claim. Its opening papers failed to eliminate factual disputes over whether it performed the obligation to make specified background materials and know-how available. Evidence offered for the first time in reply could not carry IBM’s initial burden.

The court remitted the joint-development claim for further proceedings and an amended judgment. It did not resolve Mullen’s fraudulent-inducement defense or declare IBM in breach; it held that the record could not support summary judgment for IBM on that agreement.

Key Takeaways

  • A contract claimant must prove its own performance as part of its prima facie summary-judgment case.
  • Reply evidence cannot repair a missing element in the movant’s opening submission.
  • Separately executed technology and trademark agreements may produce different liability and damages outcomes even within one transaction.

Why It Matters

The decision matters for New York technology transactions because delivery of know-how is often less self-proving than delivery of a physical asset. Parties should define repositories, access credentials, file inventories, acceptance steps, delivery notices, and audit records so later performance can be demonstrated.

Litigators should build each agreement’s proof separately and front-load it in the moving papers. A stated payment amount can measure damages once breach is established, but it does not eliminate the need to prove every condition and performance element.

The decision also underscores a recurring New York appellate lesson: statutory text, the procedural posture, and a carefully developed record work together. Practitioners should preserve the facts that connect the governing rule to the requested remedy rather than rely on labels or broad policy assertions.
