Sintx Technologies Draws Heavy Retail Buzz On New Patent Push, Subsidiary

Retail chatter around Sintx Technologies surged on Thursday following the company's announcement of a newly issued international patent and the formation of a wholly-owned agribiotech subsidiary.

Sintx Technologies closed 8.3% lower at $2.81 on Thursday, with shares slipping another 3.2% to $2.72 in after-hours trading.

The advanced ceramics developer for medical applications said it has received an international Patent, which protects the antimicrobial applications of its silicon nitride compound within agricultural environments. 

The patent forms part of a broader intellectual property portfolio addressing the antimicrobial crop protection market.

SINTX also announced the establishment of Sintx Agribiotech Inc., an independently operated unit tasked with developing and commercializing silicon nitride-based technologies for agricultural and environmental applications. 

The subsidiary will operate separately from the firm’s core medical device business and have its own management team.

CEO Eric Olson said the company sees wine production as one of the most promising early applications for the new technology.

Internal research previously published by the company showed that silicon nitride reduced the growth and sporulation of Plasmopara viticola, the pathogen responsible for grapevine downy mildew, by up to 90% on grape varieties such as Cabernet Sauvignon and Cannonau. 

The study indicated that silicon nitride caused no phytotoxic effects and may offer a sustainable alternative to copper-based fungicides, which face increasing regulatory scrutiny.

On Stocktwits, retail sentiment was ‘extremely bullish’ amid a 7,500% surge in 24-hour message volume.

One user viewed the recent pullback in Sintx shares as overextended and suggested accumulating the stock below key price levels.

Meanwhile, another user drew parallels to a previous patent-related move in February that preceded a brief rally.

The stock has declined 23% so far in 2025.
