Advanced Patent Reverse Engineering & Litigation-Ready Claim Charts
We don't just provide standard Evidence of Use. TAEUS delivers litigation-ready claim charts backed by advanced software, hardware, and semiconductor reverse engineering.
Litigation-Ready Evidence to Secure Your Market Advantage
In modern intellectual property litigation and assertive licensing, generic claims get thrown out of court. Many offshore firms provide basic, lightweight "Evidence of Use" (EoU) charts—which might be enough to justify a patent purchase, but will never hold up in a high-stakes courtroom dispute.
At TAEUS, we do much more than basic Evidence of Use. We deliver deeply technical, litigation-ready claim charts backed by objective, empirical data. Furthermore, we don't just hand you a report and walk away; we defend our findings by providing expert witness services directly from the engineers who performed the hands-on reverse engineering.
Our approach is strictly goal-oriented. We thoroughly dissect your target patent claims and industry standards to understand the technical minutiae before we begin testing, ensuring you get the most cost-effective, precise data required to win.
Specialized Reverse Engineering Across High-Tech Industries
With well over 100 combined years of high-technology expertise, our engineering teams are equipped to Take Apart Everything Under the Sun—delivering exact data from simple briefings to complex, color-coded claim charts.

Hardware & PCB Teardowns
From printed circuit boards (PCBs) to consumer electronics and touchscreen displays, our hardware reverse engineering team maps component architecture and functionality directly back to your patent claims.
Software & Firmware Code Analysis
Uncover hidden software features buried in binary code. Standard discovery rarely uncovers deep software infringement. Our team specializes in complex code analysis, utilizing static/dynamic testing to move from compiled object code (the ones and zeros that make electronics work) back into readable source code to document infringement in proprietary algorithms and operating systems.


Semiconductor & Integrated Circuit (IC) Analysis
Navigate the complexities of microelectronics. We provide advanced semiconductor reverse engineering, including chip package teardowns, layer-by-layer deprocessing, and circuit extraction to identify patent infringement at the nanometer level.
Case Study 1
When the European Commission needed to verify if Microsoft's instructions for writing compatible code for the Windows OS actually worked, they hired TAEUS Europe Limited (our UK subsidiary) to conduct a massive antitrust investigation. Our team successfully reverse-engineered the entire Microsoft Windows operating system to test the compatibility instructions. We proved beyond a shadow of a doubt that the instructions were faulty, resulting in the European Commission levying a historic fine of over 1 billion EUR against Microsoft.
Case Study 2
In a major dispute over wireless garage door opener technology, we were hired by Lear to prove that a competitor was infringing on their patents. The target technology had scrambled its code using extreme, NSA-level security to prevent access. TAEUS successfully overcame the security matrix, took the compiled object code, and analyzed it back into source code. This allowed us to map the code directly to the patents and definitively prove infringement—a feat nobody else in the industry could achieve.
Frequently Asked Questions About Patent Reverse Engineering
What is reverse engineering?
In the context of intellectual property, reverse engineering is the process of disassembling, analyzing, and testing a commercially available product to understand exactly how it works, how it was constructed, and what technology is inside.
At TAEUS, we use advanced hardware teardowns, semiconductor circuit extraction, and software decompilation (to name a few) to map a product's actual functionality back to specific patent claims. This provides companies and legal teams with the objective, empirical data needed to definitively prove patent infringement and build rock-solid Evidence of Use (EoU) for licensing or litigation.
How does reverse engineering support a patent infringement lawsuit?
Reverse engineering provides the empirical, technical data required to bridge the gap between a patent's claims and a competitor's actual product functionality. It turns suspicion into documented Evidence of Use (EoU).
What is the difference between standard Evidence of Use (EoU) and a litigation-ready claim chart?
Standard Evidence of Use charts are often lightweight overviews used to gauge if a patent has general commercial value. They typically do not go deep enough to prove infringement in a court of law. A TAEUS litigation-ready claim chart is an exhaustive, bulletproof mapping of engineering data, source code, or semiconductor circuitry directly to patent claims, designed to withstand intense cross-examination.
Can you reverse engineer proprietary or compiled software?
Yes. Our software reverse engineering team specializes in extracting and analyzing compiled object code (binary code), black-box testing, and system behavior tracking. We take compiled object code and analyze it back into a readable format to compare directly with patent claims, even when protected by advanced encryption or security protocols.
What industries benefit most from semiconductor reverse engineering?
Companies involved in telecommunications, automotive electronics, computing hardware, and IoT devices rely on semiconductor reverse engineering to protect their microchip architectures and proprietary IC designs.
