Securities, M&A & Corporate Governance Litigation

In today’s market, litigators with experience in securities, corporate governance, and M&A-related (collectively, “securities litigation”) matters need to leverage their broad experience to serve as both advocate and as counsel and strategist, focused on helping clients to overcome not just a legal issue but a collective business problem.

Federal Circuit Backs PayPal

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....Read more

Rapid Ruling: Fifth Circuit Affirms Winston Win on Summary Judgment the Day After Oral Argument

Winston recently secured a total victory for our clients, KVP Energy Services, LLC and other affiliated defendants, at the U.S. Court of Appeals for the Fifth Circuit. Plaintiff BHI Energy I Power Services LLC filed suit in the U.S. Northern District of Texas in September 2022, alleging US$150M in damages in connection with causes of action for misappropriation of trade secrets, unfair competition, and various other business torts and statutory violations. Winston scored an important early win in January 2023 by defeating BHI Energy’s motion for preliminary injunction. After a year of extensive discovery, Winston moved for full summary judgment on behalf of all defendants. In a strongly worded opinion, the district court granted Winston’s summary judgment motion and dismissed the entirety of BHI’s lawsuit....Read more

Law Glossary

What Is a Class Action?

A class action is a procedural device that allows one or more persons, usually plaintiffs (though federal and state procedural rules also authorize defendant classes) to file suit on behalf of a group of similarly situated persons. Federal law defines a class action as “any civil action filed under Rule 23 of the Federal Rules of Civil Procedure or similar State statute or rule of judicial procedure authorizing an action to be brought by 1 or more representative persons as a class action.”  28 U.S.C. § 1332(d)(1)(B), (d)(8)....Read more

What Is Removal Law?

Removal is a procedural mechanism through which a case filed in state court may be transferred to federal court upon the request of one or more parties. Actions filed in state court over which a federal court would have original jurisdiction may be transferred—or removed—to federal court under the removal statute, 28 U.S.C. § 1441. Generally speaking, removal is possible if (1) the plaintiff(s) and defendant(s) are citizens of different states and the case places more than $75,000 in controversy (so-called “diversity” jurisdiction), or (2) the case turns on issues of federal law (so-called “federal question” jurisdiction). In many cases, defendants prefer to be in federal court, and so defendants often analyze early in the case whether removal is possible. ...Read more

What Are Dark Patterns?

Dark patterns are deceptive or manipulative designs on digital platforms that trick users into making unintended choices. Dark patterns can appear as designs that create misleading impressions, hide or delay disclosure of material information, lead to unauthorized charges, or obscure privacy choices. Some examples include advertisements deceptively formatted to look like independent editorial content; non-descriptive dropdowns, arrows, or small icons to hide the full cost and other terms, free trials that automatically convert to recurring subscriptions; and prominent cookie-consent banners that hide cookie-rejection options....Read more
