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

Winston Blunts Earnout Payment

Following a bench trial in Fall 2024, a New York trial court ruled in March 2025 that Cresco Labs, Inc. was not required to pay a US$45M earnout under a merger agreement. The court found that Cresco did not receive “commercially reasonable access” to New York’s adult-use cannabis market, which was supposed to be subject only to a non-competitive application or approval process. Adopting Cresco’s arguments, the court determined that only the Office of Cannabis Management and Cannabis Control Board could decide when and how applicants access the adult-use market. The court agreed that regulators required Cresco to pay a significant one-time fee, prioritized other applicants, and had broad discretion over approvals. This win supports claims that New York’s adult-use program lacks details and clear entry paths, frustrating industry leaders’ efforts to develop a robust adult-use market....Read more

What Is the Equal Rights Amendment?

Currently, the Constitution does not guarantee that all the rights it protects are held equally by all citizens without regard to sex. With 24 words, the Equal Rights Amendment would change that. It would provide that “[e]quality of rights under the law shall not be denied or abridged by the United States or any State on account of sex.” It would also give Congress the power to enforce that constitutional guarantee by passing legislation....Read more
