43IT
43IT analyzes ECU and embedded-system firmware for litigation. We help claimant-side legal teams, patent holders, and courts understand what software actually does.
From bits and bytes to court-ready expert evidence.
Our work starts where source code is unavailable but the binary implementation matters.
Finding defeat devices in ECU firmware
We identify and explain ECU functions and calibrations relevant to alleged defeat devices and emissions-control strategies.
Software, calibration and control-strategy disputes
We investigate whether ECU software, calibrations, updates or diagnostic data explain vehicle defects, component damage or systematic behavior.
Firmware-level infringement analysis
We analyze embedded firmware at the binary level and apply lawful reverse engineering to map implementation details to specific elements of technical patent claims.
Our Diesel Scandal work built a rare combination of lawful software reverse engineering, automotive firmware expertise and litigation experience.
We work directly with ECU and embedded firmware binaries, not only externally observed vehicle behavior.
Our findings are documented, reproducible and written so lawyers, experts and courts can use them.
We understand emissions systems, diagnostics, calibrations, communication protocols and measurement setups.
Specialists for PowerPC, SuperH, TriCore, Ghidra workflows and internal tooling for binary mass analysis.
Expert Evidence
We support matters from early technical case assessment through written reports, technical exhibits, disclosure questions, expert meetings and oral evidence.
