The patent granted in China further strengthens Spermosens’ global intellectual property portfolio, which already includes granted patents in key markets including Europe, the United States of America, Japan, South Korea, Australia, South Africa, Hong Kong, Singapore, Canada, Mexico and Israel. The protection covers both the method and system underlying the JUNO-Checked technology, providing long-term exclusivity for the Company’s approach to assessing critical sperm function.

Tore Duvold, CEO of Spermosens, comments: “China is one of the world’s largest and fastest-growing fertility markets, with a strong need for improved diagnostic tools. The granted patent represents an important step in securing our IP position for JUNO-Checked in a market with significant clinical activity. The technology offers a functional way to evaluate sperm and egg interaction, a key factor that cannot be assessed with today’s conventional tests. The patent enables us to pursue dialogue with potential partners who could adapt and commercialize JUNO-Checked for clinical use in China.”

About JUNO-Checked

JUNO-Checked is a patented diagnostic technology developed by Spermosens to assess the ability of sperm cells to bind to the JUNO receptor on the egg. This is a crucial step in fertilization and cannot be evaluated with conventional semen analysis. By replicating this biological process in vitro, JUNO-Checked provides a direct functional measurement of sperm and egg binding. This offers new insight for the assessment of male fertility in IVF clinics and sperm banks.

About the Chinese Market

China is one of the largest fertility markets globally. More than 1 million assisted reproductive technology (ART) cycles are performed each year, resulting in over 300,000 ART-related births. The fertility services market was valued at approximately USD 3.3 billion in 2023 and is projected to reach USD 5.9 billion by 2030. Infertility affects an estimated 25 percent of couples trying to conceive, with male factors contributing significantly. Diagnostic semen analysis is routinely used in IVF clinics, hospital laboratories and sperm banks, representing a substantial addressable segment for advanced functional sperm tests such as JUNO-Checked.
