Litigation Update - Pre-Trial Conference

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, announces an update to its litigation against Samsung for the willful infringement of the Group's IP.

The Pre-Trial Conference began yesterday and is still ongoing. It is a normal part of the judicial process and is being overseen by His Honour, Judge Rodney Gilstrap, of the Eastern District of Texas. The transcripts of the first day of proceedings show that the Judge has ruled on a number of motions that had been submitted by Nanoco and Samsung. The more significant rulings are shown below:

A number of other motions were ruled upon during the pre-trial conference with no material surprises or disappointments for Nanoco. The Judge agreed to issue a summary judgment order of non-infringement with respect to red quantum dots. Nanoco did not oppose this motion, as its trial strategy is focused on green dots to limit the number of arguments to be presented to the jury in the time constrained one week trial. This has no impact on the number of allegedly infringing units as all displays (TVs and monitors) contain green and red quantum dots, with the former outnumbering the latter in a ratio of around four to one.

The rulings above are in addition to the previous public ruling by the Judge that rejected Samsung's request to change the definition of a molecular cluster compound previously ruled on in the Markman Hearing. We expect the formal Orders of the court with respect to these motions to be handed down shortly but do not expect any material change in the decisions shown in the transcripts.

Brian Tenner, Chief Executive Officer of Nanoco Group plc, said:

"So we are going to trial. We are in a strong position: the net result of rulings on the pre-trial conference motions preserve all of Nanoco's damages models and their expert testimony, as well as the full testimony of our technical expert Dr Brandi Cossairt. The earlier rejection of Samsung's motion to re-open a Markman definition was also an important finding in Nanoco's favour. Being able to selectively choose the claims to bring to trial on the back of the emphatic win at PTAB has also undoubtedly added to this strength.

"We must not be complacent as the trial still awaits and its outcome is uncertain. However, the recent events noted above have added to the strength of our belief and confidence in our case. We continue to focus and work industriously towards a favourable outcome to the trial and a substantial inflection point for Nanoco's prospects and shareholder value."

About Nanoco Group plc

Nanoco (LSE: NANO) harnesses the power of nano-materials. Nano-materials are materials with dimensions typically in the range 1 - 100 nm. Nano-materials have a range of useful properties, including optical and electronic. Quantum dots are a subclass of nano-material that have size-dependent optical and electronic properties. The Group produces quantum dots and other nano-materials. 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 Display, Sensor and Electronics markets. An interesting property of quantum dots is their absorption spectrum. Nanoco's HEATWAVE™ quantum dots can be tuned to absorb light at different wavelengths across the near-infrared spectrum, rendering them useful for applications including image sensors. Another interesting property of quantum dots is photoluminescence: the emission of longer wavelength light upon excitation by light of a shorter wavelength. The colour of light emitted depends on the particle size. 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 applications including displays, lighting and biological imaging.

Nanoco was founded in 2001 and is headquartered in Manchester, UK, with a US subsidiary, Nanoco Inc., in Concord, MA. Nanoco continues to build out a world-class, patent-protected IP portfolio generated both by its own innovation engine, as well as through acquisition.

Nanoco is listed on the Main Market of the London Stock Exchange and trades under the ticker symbol NANO. For further information please visit: www.nanocotechnologies.com.
