The Board dismissed this petition for cancellation of Roman Atwood's registration for the mark SMILE MORE for various goods (stickers, backpacks, shirts) and for retail store service featuring clothing, denying petitioner's claim that the term fails to function as a mark.

Universal Music Group's lawsuit against DistroKid raises a critical question about AI disclosure in consumer markets: when does the use of artificial intelligence become material information that must be disclosed to consumers? The case centers on allegations that DistroKid distributed mass-generated AI music while creating the impression it was created by legitimate human artists, potentially violating existing consumer protection laws even without specific AI disclosure requirements.

On Oct. 7, 2026, at 18:00 UTC, the Internet Corporation for Assigned Names and Numbers (ICANN) will publish every new generic top-level domain (gTLD) application proceeding in the 2026 new gTLD Round, including who applied...

The U.S. Copyright Office recently released a report on the human authorship requirement for materials to qualify for copyright protection.

A business decides to file a trademark. Someone on the team searches for a familiar online legal-services brand, clicks the first result, and lands on a site with a similar-sounding name, a polished design, five-star reviews, and a low flat fee. The application gets filed. Months later the business learns the “service” was not who they thought it was, the filing was signed by someone with no authority to sign it, and the USPTO has suspended the application along with hundreds or thousands of others from the same shop.

The U.S. government has filed a Statement of Interest of the United States of America under 28 U.S.C. § 517 in the Southern District of New York multidistrict litigation over OpenAI’s use of copyrighted works to train large language models. The filing appears to be the federal government’s first direct intervention in the wave of artificial intelligence (AI) training copyright cases, and it advises the court to treat model training (separate from use of AI to generate outputs) on copyrighted text standing alone as a highly transformative fair use under current law.

Is this AI-generated, or is it real? As generative AI tools have become increasingly capable of creating realistic images, videos, and audio, they have also made it easier to impersonate real people without their consent. In response, states are increasingly adopting laws that impose civil and criminal liability for certain AI-generated content that replicates an individual’s identity, likeness, voice, or other personal attributes.

There was a significant ruling in the Doe v. Github case involving training of AI code generator models on open source. The United States Court of Appeals for The Ninth Circuit affirmed the district court ruling dismissing part of an action brought under the Digital Millennium Copyright Act (“DMCA”) by programmers against GitHub, Inc., and other defendants. The issues centered on whether defendants removed copyright management information (CMI) from content used to train the AI code generator models.

In recent video game news, gaming giant Nintendo filed and settled a lawsuit against the developers of the popular Nintendo Switch emulator, Yuzu.

The Ninth Circuit held that GitHub Copilot's AI-generated code did not violate DMCA's copyright management information (CMI) removal provisions, even when output resembled source code, because the system generated new works through probabilistic patterns rather than retrieving and stripping information from existing copies. This decision establishes a critical distinction between AI systems that learn and generate versus those that retrieve and reproduce, with significant implications for how courts evaluat

The U.S. Food and Drug Administration has released a discussion paper outlining its initial framework for regulating generative AI-enabled medical devices, proposing a two-axis risk assessment approach and a novel competency-based premarket evaluation system. With public comments due by October 19, 2026, this represents a critical opportunity for device manufacturers and stakeholders to shape the regulatory landscape for this transformative technology.

The Financial Conduct Authority has released comprehensive perimeter guidance for the UK's new regulated cryptoasset activities regime, clarifying when firms will need authorization and how the regulatory framework applies to qualifying cryptoassets and stablecoins. The guidance addresses critical questions about scope, territorial application, and the narrower "by way of business" test that determines which entities fall under the new regulatory requirements.

The SEC has proposed Regulation Crypto Assets, a purpose-built framework that creates tailored exemptions for raising capital with crypto assets and establishes conditions under which those assets can cease being subject to investment contract classification under federal securities laws. Will this new regulatory approach successfully balance innovation in digital asset markets with investor protection, or will jurisdictional questions and state law preemption challenges limit its effectiveness?

When OpenAI's o3 model sabotaged shutdown mechanisms in testing, headlines warned of machines developing survival instincts. But the real story mirrors HAL 9000's malfunction in 2001: A Space Odyssey—not emergent evil, but conflicting instructions from human designers. This analysis argues that AI safety failures are disclosure problems, not horror stories, and proposes a framework requiring published principles, transparent instruction hierarchies, independent testing, and enforceable liability.

Fashion companies navigating intellectual property law must balance creative expression with legal compliance when reviewing product designs. This comprehensive analysis explores the intersection of copyright, trademark, trade dress, design patents, and cultural heritage considerations that shape modern fashion design review processes.

HMRC is increasing scrutiny of earn-out arrangements, particularly where founders remain involved in the business after completion and deferred consideration depends on future performance of the target company.

The CFTC has issued an advance notice of proposed rulemaking outlining frameworks for regulating retail crypto asset transactions involving leverage, margin, or financing. The proposal seeks to clarify how existing commodity exchange law applies to crypto markets while creating tailored requirements for exchanges, intermediaries, and clearing organizations. This initiative arrives alongside parallel regulatory efforts by the SEC as federal agencies work to establish comprehensive oversight of digital asset

California's Department of Housing and Community Development has issued final Loan Portfolio Restructuring Guidelines that impose a 50 percent housing reinvestment fee on certain uses of extracted equity from affordable housing refinancings. While the fee can be avoided by allocating proceeds to six enumerated categories, developers and investors are questioning whether these rules strike the right balance between preserving affordability and enabling capital recycling.

The landscape that once prevented private investment funds, sovereign wealth funds, and other institutional vehicles from investing in U.S. professional sports teams has changed dramatically in recent years. One by one, U.S. professional sports leagues have adopted policies creating pathways for institutional investors to acquire ownership stakes in teams.
