Litigation update

 

Nanoco seeks damages for infringement of IP by Shoei

 

Nanoco Group plc (LSE: NANO), a world leader in the development and
manufacture of cadmium-free quantum dots and other specific nanomaterials
emanating from its technology platform has filed an answer and counterclaims
to the complaint for declaratory judgement originally filed by Shoei Chemical
Inc. and Shoei Electronic Materials, Inc. (together, "Shoei") in the US
District Court for the Eastern District of Virginia.

As detailed in the Group announcement on 27 November 2025, Shoei filed a
declaratory judgement action claiming it is not infringing a number of
Nanoco's patents.

Subsequently, the Board has evaluated next steps with legal counsel and
concluded that it has a number of counterclaims against Shoei for infringement
of Nanoco's intellectual property. As part of the counterclaims, Nanoco seeks
damages for infringement of U.S. Patent No. 7,588,828, US Patent No.
7,803,423, US Patent No. 7,867,557 and US Patent No. 8,524,365.

Shoei acquired substantially all of the assets from Nanosys, Inc. ("Nanosys"),
another manufacturer of quantum dots, for an undisclosed sum in September
2023. Shoei is a supplier of quantum dots to a number of globally significant
technology companies. At this stage, the counterclaims do not specify the
quantum of monetary damages sought by Nanoco and it may take some time before
this is established.

Nanoco has retained Caldwell, Cassady and Curry ("CCC"), an IP law firm based
in Dallas, Texas, USA, to represent it in patent enforcement and litigation.
CCC was one of the legal firms involved in Nanoco's successful litigation
against both Samsung and LG Electronics.

This case is expected to come to trial within the calendar year 2026 and is
currently being funded from the Group's existing cash reserves. Shareholders
are reminded that there can be no guarantee of success in a lawsuit, or as to
the monetary damages that may be awarded if the jury and/or court finds in
favour of Nanoco.

The Board of Nanoco will continue to update shareholders as appropriate.

 

Dr Jalal Bagherli, Nanoco's Chairman, commented:

"Nanoco has on multiple occasions proven the value and validity of its IP
through the Samsung and LG litigation processes. As a Board, we have been
clear in our commitment to defending our IP to ensure a fair outcome for
shareholders of Nanoco, and have the financial resources to do so.

 

As with previous litigation that the Board has overseen, while there is
potential for damages, litigation itself carries considerable inherent risk
and the Board must weigh the opportunity versus the cost. Having taken legal
advice and given Shoei's position in the global technology supply chain, the
Board believes that it is in the best interests of shareholders to both defend
the Shoei claims of non-infringement, and pursue counter claims for
infringement.

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.
