Today, 1 June 2023, marks the launch of the Unified Patent Court (UPC) and the Unitary Patent (UP) system after many years of preparation by the European Union and its members. As of today, the UPC has jurisdiction for patent litigation throughout the 17 member states which have ratified the Agreement on a Unified Patent Court (UPCA). From today onward, newly-granted European patents can also be brought into force as Unitary Patents, providing coverage for the 17 UPC member states through a single validation.

Any existing European Patents that have not been opted out are now automatically subject to the UPC’s jurisdiction. However, you can still choose to opt your patents out throughout the initial transitional period of at least seven years, provided that those patents are not subject to litigation at the UPC. Once opted out, patents will be subject to the jurisdiction of the competent national courts instead. Opt-outs can also be registered for pending European patent applications.

During the three-month sunrise period which ended yesterday, a total of nearly 474,000 patents and patent applications were opted out. Although precise figures are hard to calculate, it has been estimated that this represents somewhere between about 40 and 60% of all eligible patents and patent applications, with the number expected to continue to rise now that the court is open for business. It will be very interesting in the coming weeks and months to see how widely the UPC is adopted as a forum for patent litigation instead of national courts, and to see if any sectoral trends begin to emerge.

In other news which was announced at a late stage of the sunrise period, it has been confirmed that (subject to a confirmatory vote by the UPC’s Administrative Committee) Milan will host the third branch of the UPC’s Central Division, which was relocated from London due to Brexit. However, no formal announcement has yet been made as to which cases will be handled in Milan, and it seems that the Milan branch will not be opening just yet. For the time being, therefore, cases at the UPC’s Central Division will be split between Paris and Munich as we reported previously.

With our patent attorneys eligible to practice before the UPC as registered European Patent Litigators, our team at Mathys & Squire is well equipped to assist you in carving out your individual filing and litigation strategy. As we step into the unknown, we are thrilled to watch the new system change patent litigation forever, and to be part of shaping its course.

As the Unified Patent Court (UPC) launch date approaches, the question on everyone’s mind regarding the placement of the third branch of the central division has finally been answered. Following Brexit and the UK’s subsequent withdrawal of its ratification of the Agreement on a Unified Patent Court, the UPC had to find a new location to host the central division’s third branch, which had originally been allocated to London.

After years of speculation and only two weeks before the official launch, the UPC has finally provided an update, although maybe not one that was widely anticipated. During a meeting on 8 May 2023, the Presidium of the UPC decided that any actions relating to patents in IPC section A (Human Necessities) will be assigned to the seat in Paris, and those relating to patents in IPC section C (Chemistry) will be assigned to the Munich branch.

Despite previous reports of Milan being all but confirmed as the third location, it has also been rumoured that the Italian, German and French governments are yet to agree on a division of technical classes between the three branches of the court. Given the Presidium’s characterisation of the reallocation of competencies to Paris and Munich as being “provisional”, it seems that negotiations in this respect may still be ongoing even as time runs out on the sunrise period.

As we anticipate the opening of the UPC’s doors on 1 June 2023, we will report on any updates that are released and will continue to support our clients and contacts on their UPC journey.

The Enlarged Board of Appeal has issued a preliminary opinion suggesting that it is minded to approve something close to the so-called ‘PCT joint applicants approach.’

As explained in our earlier article, the Enlarged Board has essentially been asked to decide whether, firstly, the EPO has the power to determine whether a priority right has been validly transferred to a successor in title, and secondly, whether naming the applicant for a first filing as applicant for the US only in a PCT application claiming priority thereto is enough for the purposes of introducing priority rights into the European designation. Oral proceedings have been scheduled for 26 May 2023 and the Enlarged Board has now issued its preliminary opinion on the issues.

First question

The Enlarged Board considers the first question admissible as it touches upon fundamental questions of law. This in itself is interesting because the tribunal could have taken the position that the first question did not require an answer in view of established case law and practice, according to which the EPO does have the power to decide entitlement to priority.

The Enlarged Board further addresses the scope of the first question and considers that it encompasses all situations where the applicant claiming priority is not clearly identical to the applicant of the priority application. This is because entitlement to priority issues are also said to arise outside the context of succession in title.

As regards how the first question should be answered, the Enlarged Board merely identifies a number of further questions that might usefully be discussed at the hearing. These are summarised as follows:

These further questions suggest that Enlarged Board is far from making up its mind. Indeed, the tribunal notes that opinion is also evenly divided between ‘yes’ and ‘no’ in the amicus curiae briefs and among the parties to the proceedings.

Second question

The Enlarged Board considers the second question admissible because it is relevant in many proceedings before the EPO and is a matter of ongoing discussion in the case law. 

As regards how it should be answered, the Enlarged Board says that it tends to support an affirmative answer (assuming there is an affirmative answer to the first question) on the basis that the joint filing of a PCT application (“i.e. with the consent of all applicants”) could serve as evidence implying an agreement on the sharing or transfer of the priority right. This approach seems to align closely with the PCT joint applicants approach, although problems could presumably arise if there is evidence proving the absence of any agreement, or worse, a disagreement between the PCT applicants vis-à-vis the sharing or transfer of priority rights. 

The Enlarged Board further notes that the written submissions have almost unanimously supported an affirmative answer to the second question. An affirmative answer would certainly be good news for many patentees!

We will provide further updates as the Enlarged Board referral progresses.

Following the Decision of the Administrative Council of 14 December 2022, the European Patent Office (EPO) has announced a general increase in official fees by 4-6% from 1 April 2023 – just a year after its last fee increase in April 2022. Full breakdown of the increases is available on the EPO website.

The fees with the largest increase include excess pages, excess claims per claim 16-50, and examination, whilst the filing fee for an application in character-coded format is the only one to decrease in price.

With the increases in mind, it might be sensible to pay certain fees early, before the rates go up. For example, requesting examination and paying renewal fees can be performed several months ahead of the official deadline so applicants may find it worthwhile to review their patent portfolios and check if any fee payments can be made ahead of the 1 April 2023.

For more information about the fee increases and how they may affect you, as well as to discuss any potential cost savings, please get in touch with your usual Mathys & Squire attorney, or send us an enquiry.

Data and commentary provided by Mathys & Squire has featured in articles by The Times, The Patent Lawyer, UK Tech News, L’Entrepreneur, Business & Innovation Magazine , Facts Chronicle, World Intellectual Property Review and The Business Magazine providing an update on the rapid growth in semiconductor patents applications.

An extended version of the press release is available below.

There have been a record 69,190 global patents for semiconductors filed in the past year*, up 59% from 43,380 five years ago and 9% more than the 62,770 filed in 2020/21, shows new research by Mathys & Squire, the leading intellectual property law firm.

 R&D in the semiconductor industry has underpinned the growth in technology and the intense competition within the sector has ensured that innovation continues at a fierce pace.

The global semiconductor industry is forecast to be worth $1 trillion by the end of this decade – up from $590 billion in 2021**.

US giants Intel and AMD have been locked in a years-long rivalry to dominate market share within computers by designing ever faster, higher-capacity processors. Meanwhile companies such as Cambridge-based Arm have targeted semiconductor design for mobile devices. Such intense commercial rivalries often lead to the active filing and enforcement of patents.

By 2030, the automotive sector is predicted to make-up 15% of global demand for semiconductors, up from 8% in 2021***. Another key area of growth is the ‘Internet of Things’, including everything from wearable tech to smart homes and even smart cities.

As rising geopolitical tensions have led to trade barriers for key technologies, Governments have taken steps to secure their access to semiconductors.

Last year, the US Congress passed the CHIPS and Science Act, which allocated $280 billion to promote the research and manufacture of semiconductors in the United States. The European Union is currently considering a European Chips Act in order to boost Europe’s semiconductor industry.

As the growth of domestic semiconductor industries becomes a feature of more countries’ industrial policies, we can expect new patent filings to continue as businesses seek to protect and monetise their technological advances.

China filed 55% of global semiconductor patents in the past year

In 2021-22, 55% of semiconductor patents (37,865) were Chinese in origin. China has placed a major focus on boosting domestic semiconductor production in order to reduce dependence on western technologies.

The largest individual filer in 2021/22 was semiconductor giant Taiwan Semiconductor Manufacturing Company (TSMC) Limited, which was responsible for 4,793 patents – 7% of all patents worldwide.

18,223 of the patents filed in the last year (26% of the total) were filed in the United States. The top US filer was California-based Applied Materials Inc, with 209 patents, followed by SanDisk (50 patents) and IBM (49 patents).

In contrast, the UK accounted for only 179 patents, just 0.26% of the global total.

Edd Cavanna, Managing Associate at Mathys & Squire, says: “Governments are increasingly concerned about the fragility of global supply chains and are taking steps to promote semiconductor research and production domestically. New technologies which emerge from this global technology race will be protected by patents which are likely to be fiercely enforced.”

“Global powers such as the US, China and the EU are competing to be leaders in semiconductor technology. That says it all regarding their importance for the future of the economy.”

“However, the UK lags behind other parts of the world in developing semiconductor technology. The UK Government may wish to consider whether current funding structures provide enough support to research and development in this vital field.”

Germany has finalised its approval of the Unified Patent Court (UPC), opening the UPC’s case management system and kicking off the court’s sunrise period from 1 March. The start date for the UPC is now 1 June 2023.

Germany’s move brings closer the biggest development in European IP law since the creation of the European Patent Office in 1977. The UPC has been an aspiration for the EU for half a century with several attempts at introducing a single European patent court blocked over the years before a breakthrough was finally made in 2013. Following a number of other challenges over the last few years, the UPC is on the precipice of finally coming into force.  

The UPC – presiding exclusive jurisdiction over European patent litigation – means businesses will only need to make one legal claim to enforce their patents across Europe. Costs will reduce so much that they will be comparable to making a claim in only one country previously. The new process will also make it more convenient to enforce patents across Europe for UK and EU businesses.

The start of the UPC’s sunrise period means businesses have three months to decide whether to opt their patents out of the UPC before full commencement. Businesses that anticipate having to defend their patents may wish to exercise their opt-out. Opting out would prevent competitors from ‘knocking-out’ their patent across Europe in a single judgement, making it easier to defend their patents from challenges.

Andreas Wietzke, Partner at Mathys & Squire says, “UK businesses need to seriously consider whether it is best for them to opt out of the UPC now that the Sunrise Period has begun.”

The UPC has long been a dream for the EU and provides many benefits for those wanting to enforce their patents across the single market. But for existing patent holders, it could mean an increased risk that their IP will be challenged, with a single judgement able to ‘knock-out’ patents that had applied in several jurisdictions across Europe.

The ease at which patents could be challenged may incentivise competitors to gamble and discover if they can disrupt their competition now that it is more convenient and cheaper to do so. UK businesses have three months to decide how to best protect their IP before the UPC goes into full effect.

The UPC was first agreed in 2013 but was held up for years by the domestic ratification processes of member states. Germany’s final approval of the system means that it is set to become fully operational in three months once the sunrise period elapses.

According to the existing case law of the Boards of Appeal, the standard of proof applicable to allegations of public prior use – when the evidence is in the sphere of both parties – is ‘the balance of probability’. However, when the evidence lies entirely in the sphere of the opponent, usually a higher standard of proof, i.e. ‘beyond any reasonable doubt’ (up to the hilt), applies. The two standards would entail a different degree of proof that an alleged fact is correct or has occurred.

In T 464/20, the Board stresses that the most relevant question is whether the deciding body is convinced that an alleged fact is correct or has occurred. In the case at hand, the opposition division, in acknowledging the public prior use, applied the ‘balance of probability’ standard. The appellant/patentee objected that the applied standard was not the correct one, because only the respondent/opponent had the control of the evidence.

In the decision, in a quite cumbersome sentence, the Board reasoned that even if the Board followed the patentee’s view that practically all the evidence was within the opponent’s control, the Board would still have to be convinced that the choice of the ‘balance of probability’ standard was not correct. The Board was not convinced of the incorrectness of the choice of the standard by the opposition division. In this regard, the Board noted that the opposition division correctly did not base its decision exclusively on the question whether the alleged facts were probable; rather, they were convinced of their correctness. Indeed, the opposition division was convinced both that the delivery of the product at issue was not exclusively in the hands of the opponent and that it had actually occurred.

The Board further relied on two previous Boards of Appeal decisions to support its opinion.

They referred to T 548/08, in particular reasons 4 to 11. T 548/08 deals with the type of standard of proof (‘beyond any reasonable doubt’ versus ‘the balance of probability’) to be applied to assess whether an internet disclosure forms part of the prior art. The Board commented that it was aware of the different views expressed in the case law on the standard to be applied.

However, the Board stated that the European Patent Convention’s (EPC) overarching principle of free evaluation of evidence (referring to decision G 1/12, OJ EPO 2014, A114, point 31) would reconcile the two different points of view. G 1/12’s reason 31 states that the proceedings before the European Patent Office (EPO) are conducted in accordance with the principle of free evaluation of evidence and that this principle would be contradicted by laying down firm rules of evidence defining the extent to which certain types of evidence were, or were not, convincing.

Accordingly, in reason 11, the Board stressed that the facts on which any finding of public availability is to be based must be established with a sufficient degree of certainty in order to convince the competent organ of the EPO that the facts have indeed occurred. This holds true even if the determination is made on the basis of probabilities and not on the basis of absolute certainty (‘beyond any reasonable doubt’).

T 768/20, in particular reason 2.1.2, is the second decision mentioned. This decision addresses the point whether, in assessing Art. 123(2) EPC, the implicit disclosure of a certain feature had to be proven beyond any reasonable doubt. The Board found that the applicable standard is ‘beyond any reasonable doubt’. However, the Board noted in reason 2.1.2:

“Incidentally, the Board wishes to point out that the practical relevance of the distinction between the “balance of probabilities” standard and the “beyond reasonable doubt” standard is often overestimated. Both standards are only fulfilled if the deciding body is persuaded that the alleged fact is true, which is not a matter of “just tipping the balance slightly” (see decision T 545/08, point 8 of the reasons). This is also confirmed by the passage in case law, section III.G.4.3.1, according to which “the balance of probabilities standard [is] met if, after evaluating the evidence, a board [is] persuaded one way or the other” (underlining by this board).”

The Board of T 464/20 then considered the available evidence and concurred with the opposition division that the public prior use was ‘sufficiently’ proved.

Decisions T 464/20, T 545/08 and T 768/20 deal with the standard of proof in different contexts (prior use, internet disclosure, Art. 123(2) EPC). In each of these cases, the competent Board, without denying the distinction between the two standards, appears to emphasise that what matters is that the deciding body is convinced that the alleged fact is correct or has occurred. Therefore, in the case of the standard of probability, it is not sufficient to show that an alleged fact has merely “probably” occurred.

From developments in the world of artificial intelligence (AI) and machine learning (ML), to the exploration of space, there have been numerous advancements and trends in the fields of science and technology that have garnered attention. IP has played a crucial role and has allowed innovators to reach new horizons with the help of IP protection. In this article, we have focused on some of the most exciting and influential trends that have dominated throughout 2022.

Artificial intelligence and progress in patentability

AI and ML have gone from strength to strength in the last couple of years – and the development of these technologies shows no sign of slowing down. Moving forward, it is clear – as it has been for a while – that AI will play a considerable role in our everyday lives. With these types of technology becoming progressively more commercialised, and with an increasing number of AI/ML patent applications making their way through the various patent offices, there is an escalating amount of consideration of the patentability of these technologies. For example, the UK Intellectual Property Office has recently released a guidance note on the protection of AI inventions. While this guidance note is far from perfect, it is an indication of the desire for patent offices to provide more concrete guidance for an uncertain area. As AI/ML patent applications become increasingly commercialised, we might expect to see a commensurate number of court decisions that provide further guidance for applicants.

Free-from sector continues to grow throughout 2022

The market for free-from products, which include non-dairy milk, low or no-alcohol beverages, and meat alternatives, has seen significant growth throughout 2022 due to a variety of factors. This includes health concerns, increasing awareness of food sensitivities, and concerns about the environmental impact of traditional meat and dairy products. This market is now predicted to be worth $1 trillion by 2026. Leading companies, like Unilever, are looking to significantly expand their offerings in this space in order to compete for some of this ballooning market share. As a result, there is expected to be intense competition among established free-from brands, new entrants, and traditional food and drink companies hoping to enter the market. However, as the cost of living rises, innovation relating to more cost effective methods of producing these products may come to the forefront.

Brands in this growing market are becoming more aware of the effectiveness of IP in safeguarding their market share. For example, on 9 March 2022, Impossible Foods Inc started infringement proceedings against Motif FoodWorks. Impossible Foods considers Motif’s sale of HEMAMITM – a bovine myoglobin composition which “tastes and smells like meat because it uses the same naturally occurring heme protein”, along with burgers produced containing the HEMAMITM molecule, to infringe the claims of their patent. In response, Motif FoodWorks has requested a review of the validity of Impossible Food’s patent. In addition to the legal risks, brands must also consider the potential impact on their reputation when pursuing litigation, as exemplified by Oatly’s unsuccessful suit against Glebe Farm Foods, which led to negative publicity and social media backlash. As the free-from market continues to expand, the potential for intellectual property disputes will also increase. While legal action may be necessary in some cases, the cost of litigation is a factor to be taken into consideration. Depending on the facts of the case, alternative methods for resolving disputes may be worth exploring.

Blockchain – is there a chance of a crypto comeback?

Publicly traded cryptocurrencies have suffered huge losses in the past few months, and several prominent exchanges have collapsed, so at first glance blockchain might seem to be a doomed technology. However, blockchain continues to be an area of interest across many industries and a substantial number of patent applications are still being filed for this technology. While the days of rampant speculation and valuations built on hype alone seem likely to be at an end, there does still seem to be potential for blockchain technologies to make it to market.

While cryptocurrencies and blockchain are synonymous to much of the population, many blockchain innovations – and patent applications – are not directed towards cryptocurrencies, so even if the cryptocurrency markets do not recover there is no reason to think the recent troubles are a death knell for all blockchain technologies. And from an IP point of view, the increased scrutiny of blockchains might well increase the relevance of patent protection. With hype and good marketing no longer being sufficient to gain the attention of investors, evidence of innovation is likely to become an ever more important factor in bringing blockchains to market.

Personalised therapies are on the rise

2022 has been another exciting year for personalised cell immunotherapies. These take immune cells and modify them so that they can kill cells in the body associated with a disease. To date, they have normally used the patient’s own cells, but this year saw important steps in the development of treatments based on donor cells. These have long been sought after, as they remove the need to tailor an individual’s own cells, and allow treatments to be made available faster, and potentially for a larger number of patients.

Two stories of particular interest occurred at the end of the year. Base editing was successfully used for the first time to create modified T-cells that provided a therapy for a patient with otherwise untreatable T-cell leukaemia. The complex approach was needed to allow the modified cells to kill cancerous T-cells, but not damage each other. The treatment proved a great success, and appeared to completely eradicate the cancer. In other exciting news, the European Commission issued the world’s first marketing authorisation for an ‘off the shelf’ T-cell immunotherapy based on modified cells obtained from healthy donors.

Climate change continues to spark clean tech development

In 2022, we have seen the continued growth of clean tech, with particular developments in clean energy generation and technologies to adapt to the impact of climate change. One of the most notable technological developments has been the recent announcement that scientists at the National Ignition Facility have achieved nuclear fusion ignition, producing a hydrogen fusion reaction that released more energy than was required to initiate the reaction. This is a significant milestone towards building the first nuclear fusion power plant which – if achieved – could produce energy without releasing greenhouse gases and without generating the radioactive by-products associated with nuclear fission power.  

Technological trends in clean tech are also likely to be influenced by the outcomes of the COP27 conference, especially the agreement regarding a ‘loss and damage’ fund for vulnerable countries. The fund will help developing nations adapt to climate change by financing innovation in areas such as sea defences or breeding crops that can better withstand drought. All these adaptations will require fast paced innovation to help keep up with the implications of climate change, leading to an increase in inventions and patent applications relating to climate adaptation technologies.

Unified Patent Court makes great strides – prepare for 2023 launch

Following a series of setbacks and delays in previous years, 2022 was a year in which the long-awaited Unitary Patent (UP) and Unified Patent Court (UPC) finally began to pick up momentum.

The year began with Austria becoming the thirteenth country to formally ratify the Protocol on Provisional Application, a necessary move to allow the final stages of preparatory work for the UPC to commence. These included the official recruitment and appointment of judges and court staff, and the finalisation of the Court’s IT systems. Selection and appointment of judges took place, with the final list (barring two remaining vacancies) being made public in October. However, some questions remain as to how conflicts of interest will be managed given the fact that the judicial appointments include a number of practitioners working in-house or in private practice, who will be permitted to act as UPC judges on a part-time basis.

Another significant development took place when the Netherlands pulled out of the race to host the section of the UPC’s Central Division which had originally been destined for London. This leaves Italy – specifically, Milan – as the only publicly-declared candidate to host the “London” section, which will deal with life sciences and pharma cases, with Paris and Munich hosting the other sections of the Central Division. With five months to go before the UPC is expected to open its doors, might we expect an official announcement on the final arrangements for the Central Division in the in the next couple of months?

Amid all this progress, it was expected that Germany would complete its ratification of the UPC Agreement in December 2022, paving the way for an April launch date. However, problems with finalising the electronic case management system gave rise to a last-minute delay. It’s now expected that Germany will complete its ratification in February 2023, with the start of the ‘sunrise period’ (allowing early registration of opt-outs) scheduled for 1 March 2023 and the opening of the UPC on 1 June 2023.

Although predictions of launch dates have come and gone in the past, it really looks like 2023 will be the year of the UPC and the UP system. Now is the time to make decisions whether to leave existing patent portfolios within the UPC’s jurisdiction or to opt out, as well as whether to use the UPC for infringement/revocation actions, and to decide on whether to validate European patents as UPs once the possibility becomes available.


The future is always uncertain and there are many possibilities for what could happen in the world of science and technology. One question that remains is whether cryptocurrencies will regain popularity and whether plant-based diets will continue to be a trend. However, there is one development that is certain to bring significant change to the field of intellectual property: the implementation of the UPC. With the biggest change to European patent law in decades now just months away, the Mathys & Squire team will be there to provide advice at every step of the way.
