43IT

Software Analysis for Complex Claims

43IT analyzes software directly at the binary level. We help claimant-side legal teams, patent holders and courts understand what software actually does — and we apply the same capability where source code, documentation or original developers are no longer available.

From bits and bytes to court-ready expert evidence.

Our services

We analyze compiled binaries to determine what software does – no source code required.

Litigation support

Technical evidence for high-stakes software claims.

Finding defeat devices in ECU firmware

Emissions Claims

We identify and explain ECU functions and calibrations relevant to alleged defeat devices and emissions-control strategies.

  • EGR, SCR, LNT, DPF, injection and heating strategies
  • Pre-/post-update comparisons and variant analysis
  • Temperature windows and operating-condition dependencies

Software, calibration and control-strategy disputes

Vehicle Software Claims

We investigate whether the cause for vehicle defects, component damage or systematic behavior lies in ECU code, calibrations or diagnostic data.

  • DPF regeneration strategy and DPF load models
  • Catalyst aging, component protection, and thermal management
  • Oil-quality models, maintenance counters, and service logic

Firmware-level infringement analysis

Patent Claims

We support patent holders and litigation teams in finding, verifying and documenting technical patent claim elements in accused embedded firmware.

  • Firmware binaries, bootloaders, and application code
  • Control logic and state machines
  • Sensor/actuator logic and communication protocols
  • Update packages, firmware versions, and memory content

Software disputes beyond embedded systems

Software Claims

Independent technical investigation in software and platform disputes outside the embedded automotive context – applying the methodology that underpins our embedded litigation work.

  • Application and platform behavior at scale
  • Measurement, test design and statistical evaluation
  • Methodology transferred from our embedded litigation work

Engineering services

Recovering software behavior when source code, documentation or original developers are no longer available.

Reconstructing legacy embedded systems

Embedded Software Reconstruction

We reconstruct what legacy embedded software does – from the binary, surviving documentation and observable behavior – for obsolescence, modernization, audit and re-certification projects.

  • Functional and behavioral specification recovery
  • Protocol, interface and calibration reconstruction
  • Documentation written to the same standard as our court-ready reports

Why 43IT

What sets us apart:

Binary-level evidence

We work directly with software binaries – not only with externally observed system behavior.

Built for litigation

Our findings are documented and reproducible. We present them such that lawyers, experts, and courts can understand and challenge them.

Automotive and embedded depth

We understand ECU firmware, emissions systems, diagnostics, calibrations, communication protocols, and measurement setups – and the embedded architectures behind them.

Lawful reverse engineering at scale

Specialists for PowerPC, SuperH, TriCore, and other embedded architectures. We use Ghidra workflows and internal tooling developed for binary mass analysis.

Our expertise

Technical skill applied to legal cases.

Technical findings usable in legal proceedings

Expert evidence

We support matters from early technical case assessment through written reports, technical exhibits, disclosure questions, expert meetings, and oral evidence.
