A patent infringement analysis Reading engagement usually begins the moment a Thames Valley technology business realises a competitor’s product reads onto its claims, or that its own product may read onto someone else’s. Reading anchors the M4 ‘Silicon Corridor’, the largest cluster of digital businesses outside London, and that concentration of telecoms, networking and enterprise-software companies changes the kind of infringement question that lands on a desk here. The patent is examined at the UK Intellectual Property Office in Newport and, if it is a European patent, prosecuted in Munich, but the fight over whether it is infringed is decided in a London courtroom, under English law, on evidence built long before proceedings start.
Where a Reading patent dispute is actually heard
Start with the geography, because it decides everything that follows. A patent asserted from Reading is not litigated in Reading. There is no patents court in Berkshire and no local division of any pan-European court sitting in the Thames Valley. Infringement of a UK patent, or of the UK designation of a European patent, is tried in London, and which London court hears it depends on the size and complexity of the dispute.
Substantial or technically complex cases go to the Patents Court, part of the Business and Property Courts within the Chancery Division of the High Court, sitting in the Rolls Building on Fetter Lane. Its judges are patent specialists, several of them former patent silks, and they hear the heavyweight telecoms and pharmaceutical disputes that define UK patent law. Lower-value and SME-scale claims go to the Intellectual Property Enterprise Court, or IPEC, in the same building.
The single most important jurisdictional fact for a Reading patentee is that the United Kingdom is not in the Unified Patent Court. The UK withdrew from the UPC project in 2020. A European patent validated in the UK is therefore a national right, enforced in the English courts, and it cannot be attacked or defended through the UPC’s central division. Whatever happens in Paris, Munich or Milan, a UK-designated patent lives or dies in London. For the wider national picture, see our United Kingdom IP hub.
What a patent infringement analysis Reading engagement actually involves
A rigorous Patent Infringement Analysis is not an opinion about who deserves to win; it is a structured comparison between a set of claims and a real-world product or process. A patent infringement analysis Reading clients can rely on in the Patents Court is built in a fixed sequence, and skipping any step is where weak opinions come apart under cross-examination.
The first step is claim construction, deciding what the words of the claim actually mean to the skilled person as at the priority date. English law construes claims purposively, guided by the Supreme Court’s reasoning in Actavis v Eli Lilly, which introduced a limited doctrine of equivalents alongside the normal question of ordinary meaning. Getting construction right is most of the outcome; everything downstream depends on it.
The second step is mapping. Each integer of the construed claim is set against the accused product or process, feature by feature, in a claim chart supported by evidence, whether teardowns, source code, technical documentation, or a standard specification where the patent is standard-essential. A claim is infringed only if every integer is present; a single missing integer defeats literal infringement and pushes the analysis into the equivalents question.
The third step is the opinion itself, written to be read by a judge, a licensing counterparty or a board deciding whether to fight or settle. It states the construction adopted, the evidence relied on, and the infringement position on both literal and equivalents bases, and it anticipates the obvious counterattacks, because in the UK infringement and validity are tried together and a defendant almost always counterclaims for a patent invalidation from the outset.
Standard-essential patents and the M4 corridor
Reading’s industrial profile makes one category of infringement question far more common here than almost anywhere else in Britain: the standard-essential patent. The Thames Valley is the UK home of the mobile and networking industry. Ericsson, Microsoft, Oracle and Cisco all run major operations along the corridor, Virgin Media O2 sits at Slough, Huawei has kept UK R&D in the region, and Vodafone is a short drive west at Newbury. Where you have telecoms, you have standard-essential patents.
A standard-essential patent is one that, by definition, cannot be avoided if a product implements a standard such as 4G, 5G, Wi-Fi or a video codec. You cannot design around it, because compliance with the standard necessarily practises the claim. That changes the infringement analysis fundamentally: essentiality, meaning whether the patent truly maps onto the standard specification, becomes the central question, and the claim chart is drawn against clauses of the standard rather than against a teardown.
For a Reading device maker, network operator or chipset designer, this cuts both ways. If you hold standard-essential patents, essentiality mapping is what turns a portfolio into licensing leverage. If you are accused of infringing them, the same mapping is your first line of defence, because many patents declared essential to a standard turn out, on close analysis, not to be essential at all, and an over-declared portfolio is a familiar feature of these disputes.
FRAND, injunctions and the implementer’s dilemma
Standard-essential patents come wrapped in an obligation the patentee gave to the standards body: to license on fair, reasonable and non-discriminatory, or FRAND, terms. That obligation, and the UK courts’ willingness to enforce it robustly, is why London has become the world’s leading forum for standard-essential patent disputes, which matters directly to the telecoms businesses clustered around Reading.
In Unwired Planet v Huawei [2020] UKSC 37 the Supreme Court held that an English court can determine the terms of a global FRAND licence and can grant an injunction against an implementer that refuses to take one. In practical terms, an implementer who will not accept a court-set global rate faces being injuncted out of the UK market, a remedy powerful enough to force settlement of a worldwide portfolio in a single English action.
The case law has only deepened since. In InterDigital v Lenovo the courts set a lump-sum global rate well below the patentee’s demand, and in Optis v Apple the Court of Appeal ordered a substantial lump sum covering years of past and future sales. For any Reading business on either side of such a dispute, the infringement analysis cannot stop at the claims; it has to model the FRAND exposure, because that is where the money and the leverage actually sit.
IPEC or the Patents Court: choosing the forum for a Thames Valley business
Not every Reading dispute is a nine-figure telecoms war, and the choice of court is a strategic decision in its own right. The Intellectual Property Enterprise Court exists precisely for smaller businesses and lower-value claims, and its design shapes how an infringement analysis should be pitched from the start.
IPEC caps recoverable damages or an account of profits at £500,000, and caps the costs the losing side pays at £60,000 for the liability stage and £30,000 for the quantum stage. Trials are short, usually no more than two days, with tightly limited disclosure and cross-examination, and most cases run from issue to judgment inside a year. For a Thames Valley SME facing a larger opponent, that cost certainty can be the difference between enforcing a patent and abandoning it.
The Patents Court has no such caps: full disclosure, experiment evidence, multi-day trials and costs that follow the event. It is the right venue for a high-value or genuinely complex case, and the only realistic one for a global FRAND determination. Part of what a good infringement analysis does for a Reading client is signal, early, which forum the dispute belongs in, because a claim built for IPEC looks very different from one built for the Patents Court.
What Reading’s industries actually need analysed
The mix of infringement work that arrives from the Thames Valley follows the region’s economy, and it is unusually weighted towards software and communications rather than heavy industry.
Telecoms and networking come first: cellular, Wi-Fi, networking hardware and the SEP-heavy portfolios that go with them. This is the work that most often turns on essentiality mapping against a standard rather than a straightforward product comparison, and it frequently spans several jurisdictions at once, with the UK action running in parallel with proceedings in Germany, China and the United States.
Enterprise and cloud software come second, and they are the largest single source of difficult infringement questions we see from the region. The European engineering functions of major platform, database and cloud companies sit along the corridor, and their patents raise computer-implemented invention issues, where the analysis has to grapple with claims to methods, data structures and distributed systems that may be performed across several servers and several countries.
Semiconductors, consumer electronics and connected devices come third, drawing on the chip-design and hardware presence in the area, and they typically need teardown-based claim charts and reverse-engineering evidence. Alongside them sits a steady flow of fintech, life-sciences and clean-tech work from the wider Thames Valley, each with its own evidential demands.
Typical Reading deliverables:
- Essentiality claim charts mapping standard-essential patents against 4G, 5G, Wi-Fi and codec specifications
- Literal and equivalents infringement opinions for telecoms and networking hardware
- Claim charts for computer-implemented inventions performed across distributed systems and borders
- Teardown and reverse-engineering evidence for semiconductor and consumer-electronics claims
- Non-infringement and freedom-to-operate opinions feeding design-around decisions
- FRAND exposure assessments to sit alongside the technical infringement read
Non-infringement, design-arounds and freedom to operate
Infringement analysis is not only for patentees. A great deal of the work that comes out of Reading is defensive: a company that has received a letter of claim, or one that wants to launch a product without walking into someone else’s patent.
A non-infringement opinion runs the same claim-construction and mapping discipline in reverse, looking for the missing integer, the single claimed feature the product does not have, which defeats literal infringement. Where a feature is present but arguably outside the claim’s proper scope, the analysis addresses the equivalents question head-on, because Actavis v Eli Lilly means a narrow literal reading is no longer a complete answer in the UK.
Freedom-to-operate work extends the same method across a whole product and a whole portfolio of third-party rights before launch. For a Thames Valley hardware or software business, an FTO analysis feeding into a design-around, changing the product so it no longer reads onto the claim, is very often cheaper than litigation and far cheaper than an injunction. Pairing an infringement read with a validity view, through a prior art & litigation search, tells a client whether to design around, challenge the patent, or take a licence.
How we work with Reading attorneys and in-house teams
Most instructions arrive in one of two states: a company that wants to enforce a patent and needs to know how strong its position is before spending on litigation, or a company that has been accused and needs a fast, honest read on its exposure. Both are routine, and both start the same way, with the claims, the accused product or standard, and the evidence that can actually be obtained.
We work from patent specifications and file histories, product teardowns and samples, source code under appropriate protection, technical standards and declared-essential lists, and the correspondence that has already passed between the parties. The output is a claim chart and a written opinion built to survive scrutiny, usable in settlement talks, in a licensing negotiation, or as the technical backbone of a pleaded case in the Patents Court or IPEC.
Reading sits inside the London legal and business day, minutes from the capital by rail and close to Heathrow, so work coordinated with London counsel and with in-house teams along the corridor moves inside a single business cycle. Where a deadline is tight, a response to a letter of claim, or a launch decision that cannot wait, we prioritise the analysis needed to make the immediate decision and follow with the full opinion, delivering a patent infringement analysis Reading businesses can act on quickly and defend later.

Frequently Asked Questions
Which court will hear a patent infringement claim brought from Reading?
Not one in Reading. UK patent infringement is tried in London, in the Patents Court in the Rolls Building for substantial or complex cases, or in the Intellectual Property Enterprise Court (IPEC) for lower-value SME claims. The United Kingdom is not in the Unified Patent Court, so even a European patent is enforced as a national right in the English courts.
What is the difference between the Patents Court and IPEC for a Reading business?
IPEC is built for smaller disputes: damages are capped at £500,000, the costs a loser pays are capped at £60,000 for liability and £30,000 for quantum, trials rarely exceed two days, and most cases finish within a year. The Patents Court has no caps, allows full disclosure and expert evidence, and is the right venue for high-value or FRAND cases.
We have been accused of infringing a standard-essential patent — can a UK court really impose a global licence?
Yes. In Unwired Planet v Huawei [2020] UKSC 37 the Supreme Court confirmed that an English court can set the terms of a global FRAND licence and injunct an implementer who refuses to take one. That is why so many SEP disputes affecting Thames Valley telecoms companies are fought in London, and why any infringement analysis of a declared-essential patent must also weigh essentiality and FRAND exposure.
Does the UK’s absence from the Unified Patent Court affect my patent in Reading?
It does. The UK left the UPC project in 2020, so the UPC’s central and local divisions have no jurisdiction over a UK-designated European patent. Infringement of that patent is decided by the English courts in London, entirely separately from any parallel UPC proceedings on the same European patent in participating countries.
What does a patent infringement analysis actually deliver?
A construed set of claims, a feature-by-feature claim chart mapping each claim integer against the accused product, process or standard, and a written opinion covering literal infringement, infringement by equivalents under Actavis v Eli Lilly, and the likely validity counterattack. It is written to be used in settlement, licensing or as the technical spine of a pleaded case.
How is infringement analysis different from an invalidity search?
Infringement analysis asks whether a product reads onto the claims; an invalidity or prior art search asks whether the claims should have been granted at all. In UK litigation the two are inseparable, because a defendant sued for infringement almost always counterclaims that the patent is invalid, so we usually run both reads together.
