A patented method for systematically defining and verifying computing system software based on fundamental data properties — with direct relevance to safety-critical systems developed under ISO 26262, AUTOSAR, IEC 61508, and related standards.
U.S. Patent 12,197,893 B2 describes a structured method for constructing computing system software based on a foundational concept: software behavior can be systematically defined through a limited set of data types and systematic attributes. This framework provides a consistent basis for software design, verification, and safety analysis across complex systems.
Defines the content of the data — what it represents. Safety considerations include correctness, plausibility, and integrity of the computed or received value.
Defines when data is available or processed. Safety considerations include timing constraints, deadlines, synchronization, and worst-case delay bounds.
This structured approach provides a consistent way to analyze and implement software behavior, particularly in environments where correctness and timing are critical — including systems developed under ISO 26262, AUTOSAR, IEC 61508, and related standards.
The patented framework is relevant to organizations developing safety-critical or real-time software systems. Organizations working within standards such as ISO 26262, AUTOSAR, IEC 61508, and related frameworks may find alignment between their development approaches and the patented methodology.
Electronic Control Units (ECUs), ADAS, braking, steering, and powertrain systems developed under ISO 26262 and AUTOSAR frameworks.

Jin Ming Wen is the sole inventor of U.S. Patent No. 12,197,893 B2 and the founder of DDSE Consulting, LLC, the patent owner; the author of book "Data Driven System Engineering" [DDSE] - ISBN: 9798985624908. With deep expertise in automotive ECU software development, functional safety engineering, and embedded systems architecture, the invention emerged from firsthand experience with the practical challenges of constructing safety-critical software across multiple industries.
The '893 Patent represents a fundamental insight: that the complexity of safety-critical software development can be systematically addressed by reducing all data in a computing system to exactly three types — Input, Middle, and Output — each characterized by exactly two attributes — Data Value and Data Timing. This first-principle approach enables complete, consistent, accurate, and efficient software construction and safety analysis.
