Nanoco Group (NANO.L) – Patent Litigation – Multibagger Upside

Current Price: £0.52

Target Price: £1.25 – £3.00

Upside: 2x – 6x

Expiration Date: TBD

This idea was shared by Alan.



Nanoco’s investment thesis is based on a patent infringement case that Nanoco has brought against Samsung – a multi-bagger upside if the lawsuit works out and 80-90% downside if the litigation fails. Nanoco Group is listed on LSE. Nanoco Group is listed on LSE. The US trial is expected to start at the beginning of October (having been pushed back from the 12th of September, the actual date is to be confirmed). Arguably the most interesting period for risk/reward is pre-trial so this idea is very timely. Nanoco’s operational business is the research, development, & production / licensing of nanomaterials for use in commercial applications – however, they have not yet secured any production / licensing for a live product, hence minimal revenue and minimal value in case the litigation fails. The focus of this thesis is on the legal case against Samsung.


Background of the dispute with Samsung

Nanoco was formed from a university research group (from the University of Manchester, in England), and has been researching nanoparticle and quantum dot technology for a long time, with the research & manufacturing headquarters being established in 2001.

Nanoco developed quantum dots for display purposes (e.g. high-end premium TV’s), which were importantly free from heavy metals which bring health risks such as cadmium. The quantum dots are referred to as cadmium-free quantum dots (CFQD). Importantly they also developed a method to scale up from lab to volume production.

Back in 2010 Samsung engaged with Nanoco to evaluate the quantum dot technology, and was provided samples by Nanoco. Samsung did not license the technology but went on to debut a TV with quantum dots at Consumer Electronics Show 2015. Further Samsung launched a TV with cadmium-free quantum dots in 2017 branded “QLED”. Nanoco believes Samsung has wilfully infringed a number of patents in the production of their QLED TV’s.

This 2017 article by Samsung, declares the development of CFQD technology for QLED TV’s as a breakthrough achievement by Samsung, crediting Dr Eunjoo Jang as the architect behind it.

However, you can see in this email from 2006 Dr. Jang asked Nanoco about their cadmium-free quantum dots – this is taken from the IPR materials, but there are many public documents from the PTAB IPR and the ongoing Trial available to review.

Some additional details can be found in this VIC write-up here. One important extra note from there is that Samsung does have a history of paying large awards for patent infringements:

Samsung has a long history of patent infringements, with a few examples being Acorn Technologies ($25m award for infringing 4 semiconductor patents), Solas OLED ($63m award for infringing 2 patents for OLED displays), and of course Apple ($539m award for copying smartphone features).


Legal progress in the US

Key steps achieved so far in the US legal process are as follows. NANO obtained legal funding such that they can pursue the case, even though they have limited cash resources. The funder is not disclosed but presumably would have done significant due diligence before agreeing to back the case. The funder will take a cut if successful, which would leave Nanoco with 50% of a modest trial award, and up to 80% of a larger award.

Trial process:

  • Feb. 2020 – filed complaint in the Eastern District of Texas (can follow the case on PACER, with CIVIL DOCKET FOR CASE #: 2:20-cv-00038-JRG).
  • Mar. 2021 – Markman hearing, Nanoco won 4 of 5 patents.
  • August 2022 – Samsung attempted to change the court-agreed definition of a Molecular Cluster Compound (MCC), and this was rejected.
  • Trial stayed while IPR at PTAB is held (see below), the positive PTAB outcome showing the validity of the patents allows the Trial to focus on the alleged wilful infringement and damages.
  • Aug. 2022 – Pre-Trial conference held, Nanoco damages models & expert testimony preserved. Nanoco has focused the trial strategy on green quantum dots, hence judge has agreed to issue a summary judgment of non-infringement with regard to red quantum dots.

Patent Trial and Appeal Board (PTAB) process:

  • May 2021 – Inter partes review (IPR) instituted to determine the validity of 47 claims within the 5 patents.
  • May 2022 – PTAB ruled in Nanoco’s favor in respect of all 47 claims. This was a very positive step, confirming the validity of the patents.
  • Note that Samsung is appealing the PTAB outcome, however, this is not delaying the trial going ahead.

The PTAB outcome was a material positive (shares traded at c. 27p prior to outcome being announced, having been closer to 20p when the PTAB oral hearing was heard in February 2022), and along with further positive updates (legal rejection of change to MCC definition, work package for European customer, oversubscribed fundraise), have given the shares momentum to now stand at c. 48p.

The trial is expected to start on the 3rd of October and should take one week. The jury will present their opinion including whether willfulness has been found (more on this below). The judge will take a few more months to make a formal opinion, which will include the willfulness multiplier and potential future royalty rate.


Launch of Legal Action in Germany

The USA represents approximately 35% of Samsung’s QD TV sales (as estimated by Nanoco), however, Nanoco has a worldwide patent portfolio and will be looking to either reach a global settlement with Samsung or take action in various other geographies if successful in the USA.

NANO has just announced (23rd August) that they have filed a funded lawsuit in Germany, which is one of the largest European markets for high-end TV’s. I think this is laying the groundwork to increase the pressure on Samsung, and particularly if they are successful in the upcoming US trial. There is a risk with the US trial that Samsung appeal the outcome, and attempt to drag out actually paying damages for a number of years. However, in Germany, it is much more common to grant an injunction prohibiting the sale of infringing products, if Nanoco can win the US trial it is very possible such an injunction could be granted in Germany. This would be a significant real-world impact on Samsung’s business and help push Samsung to agree to a settlement.


Damages / Settlement Possibilities

If Nanoco wins the case, it is very difficult to accurately predict damages. I will therefore suggest some figures that people can play with. Note if successful in the US trial this will award damages for historical US sales, and may or may not specify a royalty for future US sales – it will not include anything for non-US sales. However, if a settlement is reached with Samsung, my understanding is this would likely be a single amount to cover worldwide historical and future sales.

Worldwide Samsung QLED TV sales, per Omdia:

Note – current year and future year TV sales are very important. Reference.

Damages per TV – I would recommend reviewing the earnings call transcript from 3rd Nov. 2021 where CEO Brian Tenner talks at length about damages (available on TIKR). There are various damages models:

  • Nanoco would contend that their IP enabled the entire device (alas the CFQDs are very key to a premium QLED TV), and therefore you could reference the value of the entire TV (note the average retail device sales price was typically $2,000 – $2,500).
  • Another model is to consider the value of key components, given how important the CFQDs are to the picture quality (and for health/safety), this would also be an attractive model for Nanoco. Note that the Samsung QD TVs retailed for approximately $1,000 more than non-QD TV’s.
  • The lowest model is to use individual component value, i.e. of the QD film itself. I think there is a risk that historical discussions between Samsung & Nanoco may have referenced modest sales or royalty rates that may now be used to limit the damages awarded. I don’t know what these figures would be, but note that Edison estimated a royalty at $14.4 – 18.0 per TV, and Turner Pope Investments (TPI) estimated a low-end royalty in the range of $8 – 12 per TV. Both Edison and TPI “research” is paid for by Nanoco, so although the estimates will be presented as their own, you could wonder if Nanoco would have steered them a bit.

Management clearly said that the individual component value would be the most conservative model here. The calculations would go up by proving how fundamental the technology is to those Samsung TVs:

When we talk about a modest outcome, we — as I mentioned earlier, U.S. only historically only, but a modest outcome for us would also be using the worst case damages model, i.e., just looking at the individual components. If the jury were persuaded that actually know this technology fundamentally enabled the device and went for one of those other 2 higher-value models, then you would be moving significantly up from that.

For simplicity assume a low estimate of $10 per TV, and a medium estimate of $50 per TV being 5% of the approx. $1,000 increase in value of a QD TV vs non-QD TV.

Nanoco is alleging wilful infringement, and I would note the collaboration between the parties before Samsung decided to produce the quantum dots without paying Nanoco anything for the IP. If successful, this can result in a wilfulness multiplier being applied by the US judge of up to 3x, however, I have used 1.5x which may be more realistic – 1.5x rate has been the historical average in Eastern Texas:

And what that means is, did Samsung knowingly and deliberately infringe our IP? Our view is that they did, which is why we’re alleging that it was willful. And the reason that’s relevant is that, if willfulness is find, damage multipliers can be up to 3x the initial number from the jury. Now I should point out that the historical practice in the Eastern Texas is actually more like a 1.5x multiplier.

See below for Low & Medium estimates for royalty/damages amounts to approx. trial date Q3 2022, note the current market capitalization is only £153m:

The above figures do not include future years which are very significant given the 2021 run-rate of sales, and expectations per Brian Tennor’s 3rd Nov. 2021 transcript “Future sales are likely to be larger because the rate of sale of QD TVs is growing. And you then may have the kick-on benefit of generation 2 QD TVs.” If we assume annual TV sales of 10m, just slightly higher than 2021, this would produce a gross yearly royalty amount of $100m at the low estimate ($10 / TV), and $500m at the medium estimate ($50 / TV). The last of the 4 core quantum dot patents expire in early 2028, with another patent out to 2035 (I assume this is the ‘068 patent) – however as part of narrowing the case pre-trial Nanoco has withdrawn claims for the ‘068 & ‘557 patents. I am not sure exactly which of the 4 core quantum dot patents has the last expiry date, but if we assume one of those remaining expires in early 2028 this provides for c. 5 years of further coverage. Simply taking 5x the low estimate above is $500m, or 5x the medium estimate is $2,500m.


Operational Business

As can be seen from the saga with Samsung, Nanoco is very dependent on an end product being produced and sold to consumers that integrates their technology and is being paid for it.

Operationally they are focused on supplying quantum dots for infra-red sensing opportunities, they are working with 5 different customers and 8 distinct products, but it is not yet clear if any will move into production or not. The expectation is that in H2 CY 2022 they will have visibility as to whether one of these customers will move into live production in CY 2023 or not.

I don’t think the company has confirmed, but Edison has inferred that Nanoco’s “important European electronics customer” is ST Microelectronics. They also suggest that if an end customer of ST Microelectronics were to deploy the sensing application in a key mobile phone handset this could generate £15-20m of annual revenue to Nanoco.

If they can get real production orders (or agreed royalties) this part of the business could have real value, but I would not have any confidence in ascribing it significant value until they achieve this.


Financial Situation

The (expensive) litigation process is funded by a third party, and the company has done well at cutting costs in order to maximize its cash runway, further, it raised £5.4m in equity in June 2022 at 37p / share. As such they have a cash runway to CY 2025 – far past the imminent US trial (although appeals may follow), and it’s also possible they will have real production revenues prior to this point.

Cash (unaudited, as do not have audited FY results yet) in July 2022 £6.8m, debt at half year January 2022 £3.7m. For HY to Jan. 2022 cash burn was £0.3m / month. Note, a “major” work package for the European electronics customer was signed in June 2022 which helps to support the cash runway (stated by the company in August 2022 to extend to CY 2025).


Downside & Upside 

Pre-trial period:

  • Prior to the trial commencing potentially on the 3rd of October, I would view the downside as quite limited. Given most of the value ascribed currently relates to their prospects against Samsung, the legal developments to date have generally been very positive, and we have now passed the pre-trial conference point.
  • There is a real possibility that Samsung decide to make an acceptable settlement offer prior to trial. This would likely be a worldwide settlement agreement for all past & future royalties. This would mean they could avoid the risk of the jury deciding against them and possibly awarding a high amount per TV, and then also be exposed to possibly having an injunction stopping them from selling QLED TVs in Germany shortly afterward.

At trial:

  • Although it appears Nanoco is in a strong position going to trial, we don’t know what will come out during the trial process, and ultimately they could lose. If this happened I would ascribe minimal value to the operating business at this point, so would estimate the downside at c. 90%. This may be harsh, but they have not yet secured production orders for their sensing applications.
  • For upside, please see above the Damages / Settlement section, albeit the US trial itself will only award damages for US historic sales, and possibly set a royalty for US future sales.

Therefore, I view the risk/reward as incredibly compelling during this pre-trial period where a substantial settlement could be announced which would be transformational for the company. Once the trial starts it becomes much more binary, and while still interesting I would likely look to size the position much smaller.

Other points to note:

  • NANO’s largest shareholder is Lombard Odier Asset Management at c. 23%. They have historically been supportive, including subscribing to loan notes. More recently they have been reducing their holding, it should be noted the share price has increased substantially this year, and I don’t know the driver for their recent transactions i.e. portfolio/risk management vs change in view.
  • Richard Griffiths (/ related entities) was historically a large shareholder, and also supported the loan notes, however, he has recently sold down his shareholding below the reportable threshold.

      For the probabilities, are you referring to the presumed binarity after the pre-trial period? I think the point is that the pre-trial phase has good expected value.

  1. jwestern

    October 3rd is a Monday, so the latest date one could sell pre-trial is the previous Friday. Could a settlement come over the weekend in between?

    1. dt

      October 3rd is just an indicative date when the trial schedule will be made. My understanding is that this might still shift. Here is how it was worded in the press release:

      “The court has now advised that another case that was scheduled to go to trial on 12 September 2022 will now go forward as scheduled. The Company understands that the next scheduled date for trials in the Eastern District of Texas, Marshall Division, is 3 October 2022. However, no scheduling order or priority of cases has been set as yet for 3 October 2022.”

  2. PeterK

    assuming this is a typo, but the current price and target price are out by a factor of 10 ?

    1. dt

      Not sure I follow you. NANO.L stock on London Stock Exchange is quoted in British pence, so the quoted price of 50p/share is the same as £0.5/share.

      Or did you mean something else?

  3. brettrush1

    All, a bit of a side note, but what are people’s preferred method for trading international stocks? (from the U.S. at least). When deciding whether to buy directly from international exchange vs. American depositary shares are you just looking for whichever market is more liquid? Any input is appreciated.

    1. Ilja

      It seems that the court just decided to give priority to another case set on the same date. However, it sounds like NANO should now be on the top of the list for the next rescheduled date, so no more delays. The exact date will be announced later.

      From NANO CEO:

      We previously explained that this sort of change in court date is one minor downside to the system in Texas that delivers trials and outcomes at a much faster rate than most other jurisdictions in the US. […] We will update the market further when we have a revised scheduled trial date and when we know that we are first in the schedule and hence can be confident that the trial will start on the day in question. Our team of witnesses and advisers will remain in a state of readiness for a trial at any time in the short term.

  4. jwestern

    What was the timing of Samsung’s past settlements — were they immediately before trial?

    Also not sure how the Germany litigation plays into this. I imagine the ruling there isn’t contingent on the US ruling, and maybe Samsung would hold off settlement until just before the Germany case begins?

  5. Alan

    Just to update on the trial date, my understanding from being in touch with the court, is that the next available date is 31st October, however trial priority for that date has not yet been set, so it is possible it could be delayed again.

    Worth noting the movement in GBP / USD FX rate since this was shared – making any USD award or settlement worth more in GBP.

    1. Ilja

      Interesting that the same funder, who financed the US litigation, has now agreed to fund the Chinese litigation as well. A positive for the overall thesis, but could you clarify what do you mean by pre-trial settlement being “officially” in play?

      1. vko007

        Oh ok I misunderstood in that case. I’m going to assume we are still in pre-trial stage since a date has not been set (for the US trial). So, if we were only playing for a pre-trial settlement, we don’t have a date in mind to exit the position and should just hold on?

  6. giova123

    Hey, I have been studying the case. Outlook seems good, 90% of the Quantum Dots market share is for Samsung(as stated by Nanoco CEO), while other players seems sceptical to enter to this niche market, so they are giving merit to the IP. However, one question arise, is why other players do not try to license with Nanoco and comercialice legally with the IP license. Do OP have any answer about this? I mean if this is such a good tech for TVs for better quality and energy saving, why not using this.
