SoftwareLitigationConsulting.com (Andrew Schulman) partners with the following firms, which also work on technical aspects of software- and network-related litigation:

GreyB (https://www.greyb.com/)

GreyB is a technology research and analytics firm that offers IP related search, software solutions and engineering services. For past 15 years they have worked on various search assignments related prior art search, infringement investigations and as needed have reverse engineered many products to prove infringement or existence of prior art. Be it a teardown of a mobile, an OLED display, or if you need to analyse the signals of Fingerprint IC, GreyB has hands-on experience with such reverse engineering studies:

• Product teardown — Identify internal boards, components, ICs, etc. For example, in one of our previous projects we helped our client identify the NFC chip (Make & Model) in flagship smartphone models of various companies.
• Material categorization — To identify material composition. For example, in a project we helped our client identify the shape and structure of a nano-composite material used in protective coating for ceramic containers.
• Thin-film Layer categorization — We can help you identify layer structure or the material of the different layers of thin films (up to nanometer (nm) resolution). For example, in one study, we helped our client study different thin film layers of a magnetic storage layer of a hard disc drive. The objective was to confirm the presence of a ~3 nm thick carbon layer. It further involved studying the electrical and magnetic properties of different layers.
• Circuit and Signal analysis — We can perform chip-level circuit analysis for mobile or similar electronic devices, and signal analysis to analyse different signals of the ICs. For example, in a recent project, we helped a client study the signal communication between a power management IC, a fingerprint reader, and a microprocessor of a smartphone to understand the different signals and their timing during the phone unlocking event.

Products GreyB has efficiently reverse engineered and studied include:

• Mobile Phones,
• LCD/LED Televisions,
• OLED Displays,
• Smart bands,
• RFID Tags,
• Optical Connectors,
• Hard Disc Drives,
• Batteries,
• Coating Materials, etc.

GreyB has access to variety of tools such as:

• Scanning or Transmission Electron Microscopy (SEM/TEM)
• Energy-Dispersive X-ray Spectroscopy (EDX)
• X-ray Photoelectron Spectroscopy (XPS)
• Atomic Force Microscope (AFM)
• Time-of-flight or Dynamics Secondary Ion Mass Spectrometry (TOF/Dynamics SIMS)
• Signal Generators and Mixed Signal Oscilloscope
