Section 103 Obviousness Analysis (PHOSITA)

▼

Field of Art

Hair cutting appliance design and precision grooming tools, specifically focusing on spacing combs and trimming attachments with specialized geometric configurations for controlled hair cutting

Person of Ordinary Skill (PHOSITA) Profile

A mechanical engineer or product designer with expertise in personal grooming equipment, familiar with precision cutting tool design, manufacturing tolerances, and ergonomic considerations for hair trimming devices

Obviousness Rationale

A person skilled in the art would recognize that the PTD's variations represent predictable engineering extensions of the source patent's core technical concept of a specialized spacing comb. The disclosed enhancements follow standard design iteration approaches by modifying geometric configurations, component relationships, and functional parameters within the established technical framework of the original hair cutting appliance design.

Obvious Combinations & Variations

Source Patent Element

Support frame with side bars and multiple series of comb teeth

PTD Variation

Enhanced component geometry with modified tooth spacing and alignment configurations

Obviousness Reasoning

Routine design optimization through geometric reconfiguration of known structural elements, representing a predictable variation within established design parameters

Source Patent Element

Frontal and rear connector bars defining comb tooth arrangement

PTD Variation

Alternative connector bar shapes and curvature profiles to enable specialized trimming approaches

Obviousness Reasoning

Finite design solutions for modifying connector bar geometry represent standard engineering problem-solving within known technical constraints

Source Patent Element

Skin contact surface with defined offset between skin and blade set

PTD Variation

Refined surface topography and precision contact zone modifications

Obviousness Reasoning

Incremental improvements to contact surface design represent expected evolutionary development by a skilled practitioner seeking enhanced performance characteristics

Source Patent Element

Linear and curved tooth arrangement configurations

PTD Variation

Extended geometric variations exploring alternative tooth positioning strategies

Obviousness Reasoning

Systematic exploration of known geometric possibilities using standard design variation techniques

Source Patent Element

Comb tooth series with frontal and rear portions

PTD Variation

Enhanced tooth profile designs with specialized sectional configurations

Obviousness Reasoning

Predictable engineering adaptation applying known design modification principles to existing technical foundation

35 U.S.C. § 103 Summary: Based on a comprehensive analysis of US Patent 11858153, the present technical disclosure demonstrates that the claimed variations represent obvious extensions of the prior art through routine engineering modifications. A person having ordinary skill in the art would find the disclosed technical solutions to be straightforward implementations of known design principles, thereby rendering potential derivative claims non-patentable under standard obviousness criteria.
