Pax Labs Inc. Sues Stiiizy Inc. and ALD Group Ltd. for Patent Infringement
Pax Labs Inc. has filed a lawsuit against Stiiizy Inc. and ALD Group Ltd. for patent infringement regarding e-cigarette devices.

Pax Labs Inc., an e-cigarette manufacturer, has filed a lawsuit against its competitor Stiiizy Inc. and its producer ALD Group Ltd. for alleged patent infringement, as reported by Bloomberg on January 30th.

 

This lawsuit was filed in the Central District of California District Court in the United States. Pax Labs alleges that Stiiizy and ALD, based in Hong Kong, China, have been manufacturing and selling vaporization devices, including batteries and pods, in a manner similar to Pax Labs' patented technology.

 

Pax Labs has obtained US patents 11,369,756, 11,369,757, 11,766,527, and 11,759,580, which pertain to methods for leak prevention in pods and related devices. Pax Labs alleges that the aforementioned companies have infringed upon these patents.

 

Pax Labs, a former developer of the Juule-cigarette, has spun off Juul as a separate subsidiary.

U.S. Fifth Circuit Vacates NicQuid Vape MDO, Says FDA Comparative-Efficacy Standard Violated APA Procedures
U.S. Fifth Circuit Vacates NicQuid Vape MDO, Says FDA Comparative-Efficacy Standard Violated APA Procedures
According to VitalLaw on August 27, 2026, the U.S. Court of Appeals for the Fifth Circuit vacated an FDA marketing denial order (MDO) against NicQuid LLC, ruling that the agency’s comparative-efficacy standard for electronic nicotine delivery system (ENDS) applications had become a substantive rule requiring notice-and-comment rulemaking under the Administrative Procedure Act (APA). The court did not reject FDA’s authority to compare the public health benefits and risks of flavored vapes, but held that the agency could not establish a broadly binding standard through informal adjudications. The case was remanded to FDA for further proceedings.

Cochrane 2026 Update Adds Nine Trials, Keeps High-Certainty Finding That Nicotine E-Cigarettes Improve Quit Rates Over NRT
Cochrane 2026 Update Adds Nine Trials, Keeps High-Certainty Finding That Nicotine E-Cigarettes Improve Quit Rates Over NRT
Cochrane’s 2026 update of its living review on electronic cigarettes for smoking cessation included 80 randomized controlled trials involving 29,861 adult smokers, with nine trials added in this update. The review retained its high-certainty conclusion that nicotine e-cigarettes increase smoking cessation rates compared with nicotine replacement therapy. In absolute terms, about 10 in 100 people using nicotine e-cigarettes may quit smoking for at least six months, compared with about 6 in 100 using NRT. The review found no clear difference in serious adverse event rates between the two groups, while longer-term safety and the relative effectiveness of newer device types remain less certain.

Exclusive Analysis | Smoore H1 Revenue Rises 19.9% Amid Growth Concentration, Profit Pressure and Slowing Momentum
Smoore’s first-half 2026 revenue rose 19.9%, but the results revealed growing structural risks beneath the headline growth. Heat-not-burn contributed about 61% of incremental revenue and remains driven largely by one core customer, while traditional vaping markets diverged, own-brand growth slowed and China enterprise revenue declined further. Gross profit and adjusted profit lagged revenue growth, while second-quarter revenue growth slowed to about 1.9%, putting greater focus on the quality, concentration and sustainability of Smoore’s expansion.
