In December 2022, Winston convinced Judge Albright of the W.D. Tex. to reverse his tentative construction and invalidate four patents based on means-plus-function indefiniteness at claim construction in the district court. Winston also persuaded Judge Albright to deny Fintiv’s motion for reconsideration the next month. Fintiv appealed to the Federal Circuit, which affirmed the district court in a precedential opinion in April 2025. Winston overcame a significant amount of sleight of hand from Fintiv, which continually shifted the purported structure of the “payment handler” term through claim construction, its motion for reconsideration, and appellate briefs, muddying the record. Ultimately the opinion clearly distinguished the factual record from that in Dyfan v. Target, curbing patentees abilities to argue that all code or applications are a “class of structures” and not indefinite under 112(f). The Federal Circuit affirmed four of the five patents Winston invalidated for PayPal, effectively foreclosing Fintiv’s ability to revive these patents for assertion. Winston also invalidated the fifth patent at the PTAB; Fintiv’s appeal of that Final Written Decision is pending.

Sovereign Wealth Fund Sues PE Firm over Continuation Vehicle Process
On November 26, 2025, the sovereign wealth fund, Abu Dhabi Investment Council (ADIC), filed a lawsuit in the Chancery Court of Delaware against Energy & Minerals Group LP and several affiliate private investment funds (collectively EMG). The complaint seeks a preliminary injunction to stop the sale of an EMG portfolio company, Ascent Resources LLC, to a continuation vehicle that is also managed by EMG in a so-called “GP-led secondary” transaction. ADIC alleges that by selling to a continuation fund, EMG is engaging in self-dealing in breach of its fiduciary duties as manager of the selling private investment fund, in which ADIC is also a limited partner.

What Is Distributed Ledger Technology (DLT)?
Distributed ledger technology (DLT) is a database of information that’s shared and duplicated across a network of computers in different locations. In contrast to a centralized ledger, it’s a flexible system of recording information. The information on the ledger, or record, is updated by those participating in the network, rather than by a central authority. The ledger can be accessible to some or all users, and the information stored on it can be verified and audited. Peer-to-peer transfers that have value can be recorded on a DLT. The value transferred could be money, securities, or even personal information.
