Shares of Polyrizon were up 34% to $2.19 after the company said the U.S. Patent and Trademark Office published a national phase patent application by the company.
Shares of the Israel-based company, which launched its initial public offering in October, traded as high as $4.80 on Dec. 18.
The biotechnology company said the patent application is for two core platform technologies: Capture and Contain, a nasal blocker technology, and Trap and Target, designed for advanced nasal drug delivery.
