With the rapid advancement of software-driven technologies, understanding the internal behaviour of applications, firmware, and embedded systems has become increasingly important in patent infringement analysis and technical litigation. Modern products such as smartphones, IoT devices, automotive systems, communication equipment, and semiconductor devices rely heavily on complex software and firmware implementations.
In many intellectual property investigations, the original source code or technical documentation of an accused product is often unavailable, making reverse engineering an essential approach for understanding product functionality and identifying potential implementation of patented technologies.
AI-assisted reverse engineering combines traditional reverse engineering techniques with artificial intelligence to analyze source code, compiled binaries, firmware images, and embedded software more efficiently. In practice, reverse engineering technology helps analysts reconstruct program logic, identify software behavior, and detect similarities across implementations when source code is not directly available.
The integration of Artificial Intelligence (AI) into reverse engineering workflows is transforming the way source code analysis is performed. AI-assisted reverse engineering enables faster identification of software functionalities, code similarities, protocol behaviour, and architectural patterns through intelligent automation and machine learning-based analysis.
These advancements are becoming highly valuable in patent investigations, claim chart preparation, infringement analysis, and technical litigation support, where efficient and accurate technical evaluation is critical.

These reverse engineering challenges are becoming more pronounced as software systems grow in size, complexity, and obfuscation. Modern targets may include packed binaries, firmware with layered dependencies, encrypted modules, and AI-driven components, all of which increase the difficulty of source code analysis and make automated support more valuable.
AI in Reverse Engineering: How It Works
Artificial Intelligence is significantly improving the efficiency and scalability of reverse engineering workflows. AI-assisted reverse engineering combines traditional software analysis methodologies with machine learning, deep learning, natural language processing (NLP), and intelligent automation techniques to analyze compiled binaries, firmware images, and software architectures more efficiently.
Instead of relying entirely on manual interpretation of assembly instructions and execution flows, AI-driven systems can learn patterns from large datasets of source code, malware samples, firmware structures, and software behaviours to identify functionalities and generate meaningful technical insights automatically. One of the most important advantages of AI-assisted reverse engineering is intelligent pattern recognition, including:
- Recognizing code patterns
- Identifying software functions
- Detecting similarities between binaries
- Recovering symbols
- Generating pseudocode summaries
- Analyzing firmware structures
- Detecting suspicious behavior
Since the AI deals with most of the labour work, analysts can utilize their time to focus more on technical interpretation, instead of repetitive manual tasks.
Core AI Technologies Used in Reverse Engineering
Modern reverse engineering workflows increasingly rely on AI technologies to automate software analysis, identify complex code patterns, and improve the scalability of source code investigations. The following AI technologies play a major role in AI-assisted reverse engineering for source code review and patent analysis.
- Machine Learning
Machine Learning (ML) is one of the core AI technologies used in AI-assisted reverse engineering. ML models are trained on large datasets of source code, binaries, firmware images, and software libraries to recognize software patterns and functionalities automatically. In source code review, ML helps analysts classify binaries, identify software components, detect reused libraries, recognize communication protocols, and analyze similarities between software implementations. This improves the speed and efficiency of reverse engineering investigations and supports patent infringement analysis by helping identify functionalities relevant to patent claim elements. - Deep Learning
Deep Learning is an advanced AI technique that uses neural networks to analyze complex software structures, instruction patterns, and execution workflows within binaries and firmware images. In source code review, deep learning assists in opcode sequence analysis, firmware classification, software architecture reconstruction, identification of embedded functionalities, and detection of equivalent implementations. It helps analysts understand complex binaries more efficiently and improves software functionality analysis during reverse engineering and patent infringement.
- Natural Language Processing (NLP)
NLP helps AI systems understand and interpret software code similarly to human language. In source code review, NLP assists in generating pseudocode, explaining assembly instructions, summarizing functions, and identifying logical relationships between code segments. It improves software readability and helps analysts understand decompiled binaries more efficiently during reverse engineering investigations.
- Graph Neural Networks (GNNs)
GNNs analyze graph-based representations of software, such as Control Flow Graphs (CFGs), Data Flow Graphs (DFGs), and Call Graphs, to identify relationships between software components and execution paths. In source code review, GNNs assist in detecting code similarity, reconstructing software architecture, identifying software reuse, and analysing functional dependencies. It helps analysts identify structurally similar implementations and understand complex software interactions more efficiently during reverse engineering investigations.
- Explainable Artificial Intelligence (XAI)
Explainable Artificial Intelligence (XAI) focuses on improving the transparency and interpretability of AI-generated results during reverse engineering investigations. Since many AI models, particularly deep learning systems, operate as complex “black-box” models, understanding how a conclusion was generated is critical in technical litigation and patent analysis environments.
XAI techniques help analysts:
- Understand AI-generated conclusions
- Trace software similarity decisions
- Interpret function classification results
- Validate software behavior analysis
- Improve reliability of technical findings
- Provide explainable technical evidence
In patent infringement investigations, explainability is particularly important because technical findings may be used in claim charts, expert reports, and litigation documentation. Analysts and legal teams must be able to understand and justify how AI-assisted systems identified specific functionalities or similarities within a software implementation. XAI therefore improves confidence, reliability, and defensibility of AI-assisted reverse engineering results during technical investigations and litigation support activities.
AI in reverse engineering does not replace core reverse engineering techniques such as disassembly, decompilation, static analysis, and dynamic analysis. Instead, it strengthens them by speeding up function identification, reducing manual review time, and helping analysts focus on the highest-value technical questions.
