Section 103 Obviousness Analysis (PHOSITA)

▼

Field of Art

Fluid ejection systems, specifically inkjet printing technologies with non-volatile memory customization, requiring expertise in electronic circuit design, memory configuration, and device-specific addressing techniques

Person of Ordinary Skill (PHOSITA) Profile

An electrical engineer with advanced knowledge of semiconductor memory design, fluid ejection device architectures, and embedded system configuration, typically holding a master's degree or equivalent professional experience in microelectronics

Obviousness Rationale

A person skilled in the art would recognize that the PTD's disclosed variations represent predictable extensions of the source patent's core technical approach to device customization through non-volatile memory configuration. The fundamental architecture of using customization bits to modify device addressing and functionality remains consistent, with the PTD merely exploring alternative implementation strategies that would be apparent to a skilled practitioner. The variations demonstrate incremental improvements that leverage the existing technical foundation without introducing fundamentally novel conceptual leaps.

Obvious Combinations & Variations

Source Patent Element

Customization bits stored in first non-volatile memory cells to define unique device characteristics

PTD Variation

Enhanced memory cell configurations with expanded addressing and identification mechanisms

Obviousness Reasoning

Known technique of extending memory-based device identification through predictable architectural modifications that a PHOSITA would recognize as a standard design optimization approach

Source Patent Element

Control logic modifying address inputs based on stored customization bits

PTD Variation

Dynamic address mapping techniques with expanded configuration flexibility

Obviousness Reasoning

Predictable variation using standard circuit design principles to extend the original patent's addressing methodology

Source Patent Element

Disabling write access to customization memory cells after initial configuration

PTD Variation

Advanced security and configuration locking mechanisms for device-specific parameters

Obviousness Reasoning

Finite identified solution for preventing unauthorized modifications, representing an obvious design choice for a skilled practitioner

Source Patent Element

Fluid ejection device with multiple non-volatile memory cell types

PTD Variation

Expanded memory architectures supporting more complex device configuration scenarios

Obviousness Reasoning

Known technique of scaling memory-based device configuration using standard semiconductor design principles

35 U.S.C. § 103 Summary: Based on US Patent 11858265's teachings regarding fluid ejection device customization through non-volatile memory configuration, the present publication demonstrates that any claimed variations representing incremental technical extensions would have been obvious to a person having ordinary skill in the art at the time of invention. The disclosed technical implementations represent predictable variations that would be readily conceived by a skilled practitioner without requiring inventive insight beyond the foundational architectural principles established in the source patent.
