Case overview

PAE vs. IBM: A Two-Year Blockchain Patent Battle Ends Quietly

On November 22, 2022, Pardalis Technology Licensing, LLC — a patent assertion entity — filed suit against International Business Machines Corporation in the Eastern District of Texas, asserting seven U.S. patents against a broad range of IBM’s blockchain-related products. The accused products spanned IBM’s entire blockchain commercial portfolio, including IBM Food Trust, IBM Blockchain World Wire, IBM Digital Health Pass, and multiple versions of the IBM Blockchain Platform. The asserted patents cover technologies relating to data management, structured data access, and network-based information processing.

On November 21, 2024 — exactly two years after filing — the parties jointly moved for dismissal under Rule 41(a)(2) and (c). The court granted the motion the same day. Critically, the dismissal is asymmetric: all of Pardalis’s infringement claims are dismissed with prejudice, meaning Pardalis is permanently barred from re-filing those same claims against IBM on those patents. IBM’s counterclaims — which typically include invalidity and non-infringement defenses — were dismissed without prejudice, preserving IBM’s ability to revive them if Pardalis were ever to assert the patents again through another vehicle.

The two-year litigation timeline ending in a joint dismissal — with no public settlement terms disclosed — is consistent with a confidential resolution between the parties, though the public record is silent on financial terms. The with-prejudice dismissal of Pardalis’s claims is a structurally favorable outcome for IBM, eliminating future re-assertion risk on these seven patents. What drove the resolution — whether claim construction rulings, IPR petitions, or commercial negotiations — is not determinable from the public docket alone.

Dismissal terms

Asymmetric dismissal: what with- and without-prejudice means for both parties

Legal mechanism

Rule 41 joint dismissal — and why the asymmetry matters

Under Rule 41(a)(2) and (c), a court may dismiss claims and counterclaims on joint motion. Here the court granted an asymmetric order: Pardalis’s infringement claims dismissed with prejudice (permanent bar), while IBM’s counterclaims — invalidity, non-infringement — are dismissed without prejudice. This structure is commonly used in confidential settlements where the defendant wants to preserve defenses without conceding them.

Rule 41(a)(2) joint dismissal
Patent holder outcome

With-prejudice dismissal extinguishes Pardalis’s enforcement rights against IBM

A with-prejudice dismissal functions as a final adjudication on the merits for claim-preclusion purposes. Pardalis cannot re-file these seven patent claims against IBM in any U.S. court. This effectively forecloses IBM as an enforcement target for this patent portfolio, at least under the current patent numbers. Pardalis retains the right to assert these patents against other defendants.

Claim preclusion applies vs. IBM
Defendant outcome

IBM exits with counterclaims intact and no admitted liability

IBM’s counterclaims — which typically include invalidity and non-infringement contentions — are dismissed without prejudice, meaning IBM made no concessions on the merits. IBM neither admitted infringement nor paid any publicly disclosed damages. The each-party-bears-own-costs ruling removes any fee-shifting exposure. IBM retains the ability to revive invalidity arguments if the patents surface in future disputes.

No liability admitted; no fee award
Commercial implications

Seven blockchain patents survive but IBM exposure is permanently closed

The seven asserted patents remain in force and Pardalis may assert them against other blockchain platform operators, supply-chain technology vendors, or digital health credential providers. Companies operating in the IBM blockchain ecosystem — particularly Food Trust partners and Hyperledger Fabric implementers — should note that the underlying claim scope was never adjudicated, leaving validity and infringement questions open for future enforcement actions against non-IBM targets.

Official order — verbatim text

“Before the Court is the Joint Motion for Dismissal (the “Motion”) filed by Plaintiff Pardalis Technology Licensing, L.L.C. (“Pardalis”) and Defendant International Business Machines Corporation (“IBM” and with Pardalis, the “Parties”). (Dkt. No. 291.) In the Motion, the Parties request that the Court dismiss “all claims for relief asserted against IBM by Pardalis WITH PREJUDICE and all counterclaims for relief asserted against Pardalis by IBM WITHOUT PREJUDICE” under Rule 41(a)(2) and (c). (Id. at 1.) Having considered the Motion, and noting its joint nature, the Court finds that it should be and hereby is GRANTED. Accordingly, it is ORDERED that all claims for relief asserted against IBM by Pardalis are DISMISSED WITH PREJUDICE and all counterclaims for relief asserted against Pardalis by IBM are DISMISSED WITHOUT PREJUDICE. Each party is to bear its own costs, expenses, and attorneys’ fees. All pending requests for relief in the above-captioned case not explicitly granted herein are DENIED AS MOOT. The Clerk of Court is directed to CLOSE the above-captioned case.

The court’s order mirrors the language of the joint motion precisely, granting an asymmetric dismissal: Pardalis’s infringement claims are extinguished with prejudice while IBM’s counterclaims survive without prejudice. This formulation — standard in confidential settlements — ensures IBM concedes nothing on validity or infringement. The each-party-bears-own-costs clause removes any incentive for either side to seek exceptional-case attorneys’ fees under 35 U.S.C. § 285. No merits findings were issued on any of the seven asserted patents, leaving their validity and scope undetermined by this court.

The seven patents asserted by Pardalis span a broad arc of data management and networked information processing technologies, with application numbers dating from the early 2000s through the mid-2010s. US6671696B1 — the earliest — covers foundational network-based data access, while later patents such as US10409902B2 and US11126790B2 address more contemporary data management architectures. The portfolio appears structured to capture technologies underlying blockchain platforms: distributed data handling, structured query processing, and network-based information exchange.

Asserting this seven-patent portfolio against IBM’s entire blockchain commercial suite — from supply-chain transparency (IBM Food Trust) to cross-border payments (World Wire) to digital health credentials (IBM Digital Health Pass) — suggests Pardalis mapped claim language across the Hyperledger Fabric architecture broadly. For competitors operating blockchain infrastructure with similar distributed ledger and data-access layers, the portfolio represents a meaningful enforcement risk that was never narrowed by claim construction findings in this case.

Freedom to operate

Should you run an FTO against the Pardalis blockchain patent portfolio?

Any company building or licensing blockchain platform infrastructure — particularly supply-chain transparency tools, digital credentialing systems, or distributed ledger payment networks — should conduct freedom-to-operate analysis against the seven Pardalis patents. Because no claim construction order or invalidity ruling was issued in this case, the full scope of enforceable claims remains legally open. IBM resolved its exposure confidentially; other operators in the Hyperledger Fabric ecosystem have no such protection.

PatSnap Eureka’s FTO Search Agent can map your product architecture against the claim sets of all seven Pardalis patents simultaneously, flag overlapping claim language, and surface prior art candidates relevant to PTAB challenge strategies. For blockchain and distributed-data product teams evaluating launch or expansion decisions, automated portfolio monitoring can also alert you to new Pardalis continuation filings before enforcement risk materialises.

Strategic implications

What this case signals for the enterprise blockchain IP landscape

Seven patents, twelve IBM blockchain products, and a two-year E.D. Texas campaign — here is what practitioners should take away.

E.D. Texas remains the preferred venue for PAE blockchain enforcement

Pardalis’s choice of the Eastern District of Texas — a historically plaintiff-friendly docket — reflects a persistent PAE strategy in the blockchain and data management space. Companies deploying blockchain infrastructure should monitor NPE filings in E.D. Texas as an early indicator of assertion campaigns targeting the sector.

With-prejudice dismissal protects IBM but leaves the patent portfolio active

The asymmetric dismissal structure resolves IBM’s exposure cleanly, but the seven Pardalis patents were never invalidated or adjudicated as non-infringed. Blockchain platform operators, supply-chain technology vendors, and digital credential providers with overlapping technical architectures remain potential enforcement targets.
