Section 103 Obviousness Analysis (PHOSITA)

▼

Field of Art

Hair cutting appliance design and precision trimming technologies, specifically focusing on spacing combs and blade-skin interface mechanisms in personal grooming equipment

Person of Ordinary Skill (PHOSITA) Profile

A mechanical engineer or product designer with expertise in precision cutting tools, familiarity with ergonomic design principles, and understanding of hair cutting appliance component interactions

Obviousness Rationale

A skilled practitioner would recognize that the PTD's synergistic combination approach represents predictable engineering variations on the source patent's fundamental spacing comb architecture. The disclosed enhancements leverage known design modification techniques within hair cutting appliance technologies. These variations demonstrate incremental improvements that would be apparent to someone with ordinary skill in precision grooming equipment design.

Obvious Combinations & Variations

Source Patent Element

Support frame with side bars and multiple comb teeth series

PTD Variation

Enhanced component configuration with modified tooth arrangement and interaction mechanisms

Obviousness Reasoning

Predictable design optimization using known geometric reconfiguration techniques that a PHOSITA would recognize as routine engineering variation

Source Patent Element

Frontal and rear comb tooth portions with connector bars

PTD Variation

Synergistic combination of tooth geometry with alternative connector plate implementations

Obviousness Reasoning

Finite design solution space that allows systematic exploration of tooth interface configurations using standard mechanical design principles

Source Patent Element

Skin contact surface with defined offset between skin and blade set

PTD Variation

Advanced surface interaction models that refine blade-skin proximity and cutting precision

Obviousness Reasoning

Incremental improvement using known ergonomic design techniques that would be obvious to a skilled practitioner seeking enhanced cutting performance

Source Patent Element

Linear and curved tooth arrangement configurations

PTD Variation

Extended geometric variation strategies for tooth positioning and interaction

Obviousness Reasoning

Systematic exploration of known geometric design parameters that represent standard engineering problem-solving approaches

Source Patent Element

Connector bar and plate structural configurations

PTD Variation

Modified structural implementations maintaining core functional principles

Obviousness Reasoning

Routine design variation using known mechanical engineering techniques for component optimization

35 U.S.C. § 103 Summary: Based on the teachings of US Patent 11858153, the present technical disclosure demonstrates that the claimed variations represent obvious extensions of prior art, rendering subsequent claims involving similar spacing comb and hair cutting appliance configurations unpatentable under 35 U.S.C. Section 103. A person having ordinary skill in the art would find the disclosed synergistic combinations to be predictable variations within the established design space of precision cutting equipment.
