Splitting Secrets: Federal Circuits Clash Over DTSA Particularity Requirement

Historically, plaintiffs alleging federal trade secret misappropriation claims could walk the line between satisfying the minimum pleading standards set by Twombly and Iqbal, while avoiding revealing their hand too early. Bell Atl. Corp. v. Twombly, 550 U.S. 544 (2007); Ashcroft v. Iqbal, 556 U.S. 662 (2009). This is because the Defend Trade Secrets Act (DTSA) does not expressly require plaintiffs to meet a heightened pleading standard. However, in light of recent federal decisions, plaintiffs seeking relief under the DTSA may be forced to change their strategy depending upon where litigation takes place.

In trade secret litigation, forum matters. There is a growing split among federal circuit courts regarding how particularly plaintiffs must describe the trade secrets at issue, and at which point in the litigation this particularity is required. This divide is highlighted by two recent appellate decisions from the Fourth and Ninth Circuits issued one month apart that reached conflicting conclusions. While both circuits concluded the DTSA requires trade secrets to be pled with “sufficient particularity,” the Fourth Circuit requires this at the pleadings stage, whereas the Ninth Circuit gives litigants until the outset of discovery. <a href="https://www.thompsonhine.com/insights/trade-secret-quarterly-february-2026/">Continue reading</a>.

U.S. Citizenship and Immigration Services (USCIS) announced that the initial registration period for the fiscal year 2027 H 1B cap will open at noon Eastern on March 4 and run through noon Eastern on March 19, 2026.

Registration Process and Fee

If an employer wants to apply for an H-1B visa for a foreign worker, there are a few steps to follow. First, employers and their attorneys need to create accounts on myUSCIS.gov to participate in this process. Then the employer must register electronically and pay a $215 fee for each person being registered. This fee is nonrefundable and must be paid online through the pay.gov portal. It is separate from the fees that will need to be paid later if the registration is selected in the H-1B lottery. <a href="https://www.thompsonhine.com/insights/fiscal-year-2027-h-1b-lottery/">Learn more</a>.

SDNY Rules AI Communications Not Privileged

In a case of first impression and with significant implications for anyone who uses public generative AI tools in connection with legal matters, Judge Rakoff of the Southern District of New York issued an opinion on February 17, 2026, in United States v. Bradley Heppner, No. 25 Cr. 503 (JSR) holding that the defendant’s communications with a publicly available AI platform were not protected by attorney-client privilege or the work product doctrine. This ruling should serve as a wake-up call for anyone who’s ever input information into a public AI tool: sensitive information shared with public AI platforms is not confidential and privilege claims over AI-assisted work may fail. <a href="https://www.thompsonhine.com/insights/sdny-rules-ai-communications-not-privileged/">Explore further</a>.

After U.S. Supreme Court Invalidates IEEPA Tariffs, Trump Administration Turns to Other Options – What Importers Need to Know

On February 20, the SCOTUS, in a landmark 6-3 ruling, determined that President Trump’s use of the IEEPA to impose tariffs was unlawful. In its <a href="https://www.supremecourt.gov/opinions/25pdf/24-1287_4gcj.pdf">decision</a>, the SCOTUS stated: “When Congress grants the power to impose tariffs, it does so clearly and with careful constraints. It did neither in IEEPA.”

As Chief Justice John Roberts noted in the majority opinion, the IEEPA gives the president economic tools to address significant foreign threats to U.S. national security, foreign policy, or the economy. Early in his second term, President Trump declared a national emergency as to both drug trafficking and U.S. trade deficits and issued a series of executive orders imposing tariffs under the IEEPA. <a href="https://www.thompsonhine.com/insights/after-u-s-supreme-court-invalidates-ieepa-tariffs-trump-administration-turns-to-other-options-what-importers-need-to-know/">Keep reading</a>.

DOL Proposes Major Changes to Employee and Independent Contractor Classification Rules

On February 26, the U.S. Department of Labor (DOL) published a proposed rule that would fundamentally reshape how employers determine whether a worker is an employee or an independent contractor under the Fair Labor Standards Act (FLSA) and related federal laws. The proposed rule would rescind a 2024 Biden-era final rule and replace it with an analysis similar to the one adopted by the DOL in 2021, with a few modifications.

According to the DOL, the proposed rule is designed to help workers and employers “better understand how to determine when a worker is an employee and when the worker may be classified as an independent contractor” under federal wage and hour laws. <a href="https://www.thompsonhine.com/insights/dol-proposes-major-changes-to-employee-and-independent-contractor-classification-rules/">Learn more</a>.

New HSR Rule Vacated, but Its Fate Remains Uncertain on Appeal

There was substantial controversy surrounding the <a href="https://www.ftc.gov/news-events/news/press-releases/2024/10/ftc-finalizes-changes-premerger-notification-form">FTC’s issuance</a> of a new rule in October 2024 that <a href="https://www.thompsonhine.com/insights/new-hsr-rules-significantly-increase-filing-burden/">significantly increased</a> the burden on parties filing notifications under the Hart-Scott-Rodino (HSR) Act. Under that <a href="https://www.govinfo.gov/content/pkg/FR-2024-11-12/pdf/2024-25024.pdf">new rule</a>, parties were required to report transactions meeting the HSR thresholds using a new form demanding information and documentation well beyond what had been required since the HSR Act was enacted in the late 1970s. <a href="https://www.thompsonhine.com/insights/antitrust-monthly-february-2026/">Read more</a>.
