Case Study

IP Ownership Dispute — Large-Scale Corporate Archive to Court-Filed Expert Report

An investment firm needed to establish that their portfolio company — not the customer — owned the intellectual property in a jointly-developed product. The data set included terabytes of corporate archives spanning multiple years. The work evolved from data analysis into a court-filed expert report for a federal IP case.

TB-scale Data analyzed
300+ Git repos reviewed
70+ Reports produced
<100 hrs Total time

What we did:

  • Built a semantic search index across hundreds of thousands of files for full-archive analysis
  • Performed source code forensics across all repositories — millions of commits analyzed for authorship attribution
  • Scanned hundreds of thousands of source files for copyright headers and reconstructed multi-year contract history
  • Reconciled dozens of invoices totaling millions in contract payments
  • Prepared a comprehensive expert report with supporting exhibits, filed with the court under Daubert standards
  • Every deliverable verified by automated quality assurance before shipping

Expert report accepted by the court. This scope of work would typically require a team of analysts working several months.

Case Study

CNC Machine Controller Redesign — Ground-Up Embedded System for Production Manufacturing

A CNC equipment manufacturer needed a complete redesign of their machine controller. The existing design — built around two processors and 29 optoisolators — was expensive to manufacture, difficult to maintain, and couldn’t support the wireless control or expandability the company wanted. Working closely with the client’s lead engineer, the engagement spanned seven years: from initial research and prototyping through multiple PCB revisions, firmware development, and production documentation for volumes of 5,000–10,000 units per year.

7 years Engagement duration
6+ Distinct PCB designs
5 BLDC motor axes
10+ Accessory modules designed

What we did:

  • Replaced the legacy dual-processor architecture with an ESP32-based design (dual-core 240MHz) plus an auxiliary 8-bit microcontroller for the accessory subsystem
  • Evaluated and selected motor driver ICs for 5-axis brushless DC motor control at 48V, including thermal analysis, load testing, and discrete FET evaluation
  • Designed and tested the power delivery system with regulated 48V, 24V, 5V, and 3.3V rails, including PFC research and extensive bench testing with adjustable loads and precision supplies
  • Built the plasma torch interface: 240VAC torch fire control, arc voltage sensing, touch-off detection, and integration with commercial plasma cutting systems
  • Developed embedded firmware (ESP-IDF) with over-the-air update capability, WiFi host communications, and a wireless control interface — after extensive Bluetooth prototyping and latency testing proved WiFi was the better path for Windows compatibility
  • Designed a modular accessory ecosystem with marking laser integration, each module using its own I2C-connected controller board
  • Created full PCB designs (schematic, layout, Gerber files, BOM) across 6+ boards including the main controller, torch interface, evaluation boards, and accessory kit
  • Produced factory test procedures (3-stage: PCB self-check, load test/calibration, full table integration), failure mode analysis, and production manufacturing documentation

Helped deliver a production-ready controller platform that replaced the legacy hardware with a modern, wireless-capable design supporting a full accessory ecosystem — work spanning component research, schematic capture, PCB layout, firmware, power supply testing, and manufacturing documentation.
