Infringement analysis

Infringement proven, or disproven, down to the component.

When a specific product is at the centre of a licence or a dispute, the question is no longer who might infringe, but whether this product does, element by element. Our patent attorneys and engineers analyse the product itself, from documentation and teardown to software and testing, and deliver evidence-of-use charts that hold up with licensees, opponents and courts.

  • Technical analysis of hardware, software, processes and materials
  • Claim-to-product mapping with evidence of use for every element
  • Reverse engineering insight, from teardown to firmware
20+Years in patent practice

What it is

You know the product. We show exactly how it reads on the claims.

Infringement analysis is the detailed technical and legal comparison of one patent against one product, process or system. It starts where a search ends: the target is known, and the task is to prove, or disprove, that every element of a claim is present.

That takes more than reading a product page. We construe the claims, study the product in depth, and where public documents fall short, use teardown, software analysis and testing to find the evidence. The result is an opinion and a set of evidence-of-use charts your licensing team or counsel can rely on.

Our analysis services

From the product in your hand to evidence a court can use.

Patent attorneys and engineers work side by side, so the technical findings and the legal reading always agree.

01

Product and technical analysis

We take the product apart, on paper and in practice, to understand exactly how it works and which features matter for the claims.

  • Architecture, block diagrams and feature breakdown
  • Manuals, datasheets, SDKs, API docs and release notes reviewed
  • Regulatory filings (FCC, FDA 510(k), CE) mined for internals
  • Open-source code and firmware repositories examined
  • Versions, variants and regional models compared
  • Sales, launch and availability dates recorded for the damages period
02

Claim-to-product mapping

Claims construed with care, then mapped element by element to the product, so every limitation is accounted for.

  • Claim construction from the specification, file history and case law
  • Means-plus-function and functional language analysed
  • Element-by-element mapping to product features
  • Literal infringement and doctrine of equivalents assessed
  • Independent and dependent claims ranked by strength
  • Claim families and continuations screened for better-fitting claims
03

Evidence of use (EoU)

Charts that show, with cited and preserved evidence, how the product meets each element of the claim.

  • EoU charts with annotated figures, screenshots and test data
  • Every source dated, linked, archived and hashed
  • Pin cites to page, figure, timestamp or line of code
  • Gaps flagged, with ways to close them
  • Separate charts for each product, version and claim
  • Formatted for licensing decks, notices or pleadings
04

Reverse engineering insight

When public documents are not enough, we look inside the product to find the evidence that settles the question.

  • Hardware teardown and component identification
  • Board tracing and, through partners, die-level imaging
  • Software, firmware and app behaviour analysis
  • Network traffic capture and protocol decoding
  • Materials and chemical analysis through accredited laboratories
  • Chain of custody kept for every purchased sample
05

Non-infringement and design-around

For accused infringers, the same rigour applied to show what the product does not do, or how it can avoid the claims.

  • Missing-element and non-infringement charts
  • Claim construction positions that narrow the asserted claims
  • Prior art squeeze: if it reads on us, it reads on the art
  • Design-around options assessed against every claim
  • Engineering change review before release
  • Freedom to operate input for new versions
06

What we assess

Every route to infringement, tested on the facts.

Infringement is not one question but several. We test each theory that could apply to your patent and product, and tell you which are strong.

Literal infringement

Every element of the claim is present in the product exactly as claimed. The baseline test in every jurisdiction.

Doctrine of equivalents

An element is met by an equivalent that performs substantially the same function, in the same way, with the same result.

Indirect infringement

Induced and contributory infringement, where a supplier enables or encourages others, such as customers, to infringe.

Divided and joint infringement

Method steps performed by more than one party, such as a device maker, a cloud service and an end user.

Process and product-by-process

Manufacturing methods and products defined by how they are made, including imports made abroad by a patented process.

Software and system claims

Method, system and computer-readable medium claims mapped across devices, apps and servers.

Means-plus-function claims

Functional claim language construed against the structure disclosed in the specification, and its equivalents.

Standard essential patents

Claims mapped to the standard to show essentiality, then to products that implement the standard.

Territorial acts

Making, using, selling, offering and importing assessed country by country where the patent is in force.

Technologies we analyse

Specialists for every kind of product.

Each analysis is led by an engineer or scientist from the field, so the product is understood the way its designers understand it.

Option 01 of 09

Semiconductors

Chip architecture, process nodes, memory, packaging and power management. We analyse how a chip is designed and made, and where it sits in the end product.

  • Datasheets, reference designs and application notes
  • Die-level imaging and delayering via laboratory partners
  • Process node and packaging analysis
  • Chip-to-device mapping across customers
  • Supply chain tracing from foundry to brand
  • Claim charts for circuit, process and system claims

Reverse engineering

When the evidence is inside the product, we go and find it.

Public documents rarely show everything. We choose the right technique for the technology and the claim, working with specialist laboratories where needed.

Hardware teardown

Products dismantled and documented, with components, layouts and assemblies identified and photographed at every stage.

Circuit and chip analysis

Board-level tracing and, through laboratory partners, delayering and die-level imaging of integrated circuits.

Software and firmware

App and firmware behaviour observed, logged and analysed to show how claimed functions are performed.

Network and protocol testing

Traffic captured and decoded to evidence claimed communication methods and standards features.

Materials and chemistry

Composition and structure analysed through accredited laboratories for chemical, materials and formulation claims.

Process and use observation

Methods of manufacture and use documented through bench testing, demonstrations, video and public records.

Where evidence comes from

Nine sources, every one documented.

Strong charts draw on several independent sources for each element. Every item is dated, archived and preserved, so it can be relied on later.

Product documentation

User manuals, installation guides, datasheets, white papers and service manuals.

Websites, apps and video

Product pages, app stores, help centres, demos and archived web pages with dates.

Regulatory filings

FCC, FDA, CE, EMA and other filings that describe internal design and operation.

Standards and contributions

Standards specifications, change requests and company contributions to standards bodies.

Open-source code

Public repositories, firmware images and licences showing how functions are implemented.

The target's own patents and papers

Patents, publications and conference talks by the target's engineers describing its products.

Litigation and agency records

Court filings, expert reports, ITC records and prior licensing disputes involving the product.

Marketing and investor materials

Earnings calls, investor decks, press releases and trade show materials.

Purchased product testing

Products bought on the open market, then torn down, tested and documented with chain of custody.

What the output looks like

Public documents, teardown and testing, in one chart.

Each element is supported by the strongest available evidence, with a pin cite to its source, so a licensee or a court can check it in seconds.

Request an analysis
01How is infringement analysis different from an infringement search?

An infringement search looks across the market for products that may use your patent. Infringement analysis takes one known product and examines it in depth to prove, or disprove, that every claim element is present.

02What is evidence of use (EoU)?

Evidence showing that a product meets each element of a patent claim, usually presented as a claim chart with cited documents, figures, screenshots or test results. It is the basis of most licensing and enforcement programmes.

03Do you assess the doctrine of equivalents and indirect infringement?

Yes. Where an element is not met literally, we assess equivalents. We also consider induced, contributory and divided infringement where several parties perform the claimed steps.

04When is reverse engineering needed?

When public documents do not show how an element is implemented, for example inside a chip, in firmware or in a manufacturing process. We recommend it only where it adds real value to the case.

05How do you make sure evidence can be relied on later?

Every web source is archived with its date and a hash, documents are kept in full, and purchased products are logged with chain of custody, so the evidence can be verified at any point.

06Do you analyse software and standards-based products?

Yes. We analyse apps, firmware and network behaviour, and map claims to standards such as cellular, Wi-Fi and video codecs, then to products that implement them.

07Can you screen a whole portfolio against competitor products?

Yes. Portfolio screening ranks patent and product pairs by fit and evidence, then charts the strongest in full, which is how most licensing campaigns begin.

08Can you help if we are accused of infringement?

Yes. We apply the same rigour to show missing elements, build non-infringement positions, apply the prior art to the asserted reading, and assess design-around options.

09Is the analysis suitable for litigation?

Our analysis and charts are prepared to support counsel and expert witnesses. Evidence is cited and preserved so it can be relied on, and we work with your counsel on how it is presented.

10How long does an analysis take?

It depends on the number of claims, the complexity of the product and whether testing is needed. We confirm scope, timeline and fee before work starts, and offer rush options.
