ETHERNITY NETWORKS LIMITED

("Ethernity" or the "Company")

 

Grant of Key Longest Prefix Match Routing Patent

 

Ethernity Networks Ltd (AIM: ENET.L; OTCMKTS: ENETF), a leading supplier of
data processing and Passive Optical Network ("PON") semiconductor technology
for networking appliances, is pleased to announce that it has received
confirmation from the Company's US patent attorney that the United States
Patent and Trademark Office has granted Ethernity's U.S Patent No. 12425341
(the "Patent"), titled "A method for routing using longest prefix matching"
("LPM"). The Company announced on 20 June 2025 that a notice of allowance had
been issued in relation to the Patent application.

 

The Patent covers the implementation of a highly optimized method for routing
using an LPM algorithm, designed to support hundreds of thousands of routes in
few clock cycles, while eliminating the need for costly external components
such as TCAM (Ternary Content Addressable Memory). This is achieved through
Ethernity's unique firmware, which is embedded into the Company's pipeline
data processor.

 

The algorithm was originally developed to form the corner stone of a new ultra
highspeed networking design and then was integrated to become part of
Ethernity's existing UEP offering and is fully applicable for ASIC
implementation, offering a scalable and efficient approach to high-performance
routing within integrated networking platforms. In essence, this Patent
significantly strengthens the Company's intellectual property portfolio,
reinforcing its position as a technology leader in data processing for routing
applications.

 

The Patent complements and enhances the Company's planned ASSP
(Application-Specific Standard Product) offering, which is designed to support
Layer 3 MPLS routing capabilities in addition to standard Carrier Ethernet
features. This Patent builds upon Ethernity's differentiated technology stack,
which already includes its patented wireless link bonding and integrated PON
functionality. Intellectual property protected by patents is critically
important for Tier-1 OEMs, as it safeguards their deployments against
potential intellectual property infringement claims, ensuring greater legal
and commercial security.

 

While initially integrated into the UEP product, the patented design's code is
optimized for significantly higher performance, capable of operating at 10x
the throughput of the UEP design. This speed translates into exceptional
lookup times: searching 100,000 IP prefixes in 70ns (FPGA) and 17ns (mid-range
ASIC) and dropping to just a few nanoseconds for routes below 10,000. This
capability allows it to be used as a standalone IP for extremely low-latency
ASIC designs

 

Together, these innovations position the Company to deliver a highly
integrated and cost-effective silicon solutions that meets the evolving needs
of OEMs and service providers looking for advanced, scalable, and programmable
access network platforms.
