(Sharecast News) - Ethernity Networks announced on Friday that it has received a notice of allowance from the United States Patent and Trademark Office for a core routing algorithm patent, further strengthening its intellectual property portfolio in data processing and access network technologies.
The AIM-traded firm said the patent application, filed in June 2022, covers a high-performance longest prefix match (LPM) routing algorithm capable of supporting hundreds of thousands of routes without the need for expensive external components such as TCAM.
It said the innovation was embedded in its pipeline data processor and originally designed for FPGA, with potential applicability in ASICs for scalable deployment.
The LPM algorithm forms part of the company's UEP product line, and is integral to its planned application-specific standard product (ASSP) roadmap, enabling advanced Layer 3 MPLS routing and carrier ethernet capabilities.
Once granted, the patent would bolster Ethernity's differentiated offering, which already includes patents for wireless link bonding and integrated PON functionality.
"This routing patent application significantly strengthens the company's intellectual property portfolio, reinforcing its position as a technology leader in data processing and access networking," the company said in a statement.
Ethernity added that securing such intellectual property was vital for tier-1 OEMs, offering commercial and legal protection for future deployments.
The patent was expected to be formally granted following completion of administrative steps.
At 1508 BST, shares in Ethernity Networks were up 10.73% at 0.02p.
