RNS Number : 2559J  Nanoco Group PLC  27 November 2025

FOR IMMEDIATE
RELEASE
                                       27
November 2025

 

Nanoco Group PLC

("Nanoco", the "Group", or the "Company")

 

Response to non-infringement claim

 

Nanoco Group plc (LSE: NANO), notes that Shoei Chemical Inc. and Shoei
Electronic Materials, Inc. (together, "Shoei") has issued proceedings in the
US District Court for the Eastern District of Virginia seeking a declaratory
judgement of non-infringement of certain of Nanoco's patents.

Shoei acquired substantially all of the assets from Nanosys, Inc. ("Nanosys"),
another manufacturer of quantum dots, for an undisclosed sum in September
2023.

The Board of Nanoco feels it appropriate to emphasise that this claim has been
filed by Shoei in order to establish whether Shoei has or has not been
infringing a number of Nanoco's patents. The Group is evaluating next steps
with legal counsel and will update shareholders when possible.

About Nanoco Group plc

Nanoco (LSE: NANO) is a world leader in the development and manufacture of
cadmium-free quantum dots and other specific nanomaterials emanating from its
technology platform. In particular, Nanoco is a nanomaterial production and
licensing group, specialising in the production of its patented cadmium free
quantum dots (CFQD® materials) and other patented nanomaterials for use in
the electronics industries. Founded in 2001 and headquartered in Runcorn, UK,
Nanoco continues to build out a world-class, patent-protected IP portfolio
alongside its existing scaled up production facilities for commercial orders.

Nanomaterials are materials with dimensions typically in the range 1 - 100 nm.
Nanomaterials have a range of useful properties, including optical and
electronic. Quantum dots are a subclass of nanomaterial that have
size-dependent optical and electronic properties. Within the sphere of quantum
dots, the Group exploits different characteristics of the quantum dots to
target different performance criteria that are attractive to specific markets
or end-user applications such as the Sensor, Electronics and Display markets.
Nanoco's CFQD® quantum dots are free of cadmium and other toxic heavy metals,
and can be tuned to emit light at different wavelengths across the visible and
infrared spectrum, rendering them useful for a wide range of display
applications. Nanoco's HEATWAVE® quantum dots can be tuned to absorb light at
different wavelengths across the near-infrared spectra, rendering them useful
for applications including cameras and image sensors.

Nanoco is listed on the Main Market of the London Stock Exchange, holds the
