pr1or.art Inc., “Advanced Adjustable Fish Hook Apparatus Innovation,” Published Technical Disclosure No. 24-11856919_0006_PTD, Published October 26, 2025, available at https://archive.pr1or.art/24-11856919_0006_PTD
This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,856,919.

Background and Problem Solved

Conventional fish hooks often have fixed designs that limit their versatility and effectiveness in different fishing conditions. The original patent, 'Fish hook apparatus', disclosed a fish hook apparatus with a weighted head member and soft bait securing elements. However, this design has inherent limitations, such as the fixed channel size and shank stiffness, which can restrict its use with various fishing lines and baits. The present invention solves these problems by introducing adjustable features that improve the overall performance and adaptability of the fish hook apparatus.

Novelty and Inventive Step

The adjustable channel, variable stiffness shank, curved bend section, and retractable point element are novel features that distinguish the present invention from the original patent. These features provide a significant improvement in the controllability, efficiency, and safety of the fishing experience, thereby constituting an inventive step over the prior art.

Alternative Embodiments and Variations

Alternative embodiments of the invention may include different mechanisms for adjusting the channel size, such as a screw-based or lever-based system. The shank stiffness could be adjusted using materials with varying degrees of flexibility or by incorporating adjustable inserts. The curved bend section could be replaced with a tapered or angled design, and the retractable point element could be implemented using a spring-loaded or hinged mechanism.

Potential Commercial Applications and Market

The enhanced fish hook apparatus has significant commercial potential in the fishing industry, particularly among recreational and professional anglers seeking improved performance and safety. The invention could be marketed as a premium product, targeting high-end fishing gear manufacturers and retailers. Additionally, the adjustable features of the invention could be licensed to other companies, providing a revenue stream through royalties.

Field of Art

Fishing equipment design, specifically fish hook apparatus and bait systems, involving mechanical design, materials engineering, and fishing tackle optimization

Person of Ordinary Skill (PHOSITA) Profile

A mechanical engineer or fishing tackle designer with expertise in hook design, materials selection, and understanding of fishing equipment performance characteristics, typically with 3-5 years of professional experience in marine or sporting equipment design

Obviousness Rationale

A PHOSITA would recognize that the PTD's variations represent predictable design modifications to the source patent's fish hook apparatus. The proposed adjustable channel, variable stiffness shank, and retractable point elements are logical extensions of known fishing hook design principles that address common user needs for adaptability and safety. These modifications represent standard engineering problem-solving approaches within the fishing tackle design domain.

Obvious Combinations & Variations

A PHOSITA would find it obvious to modify channel dimensions as a predictable design variation to improve line compatibility, using standard mechanical adjustment techniques
Source Patent Element
Soft bait securing elements with fastener options
PTD Variation
Variable stiffness shank to accommodate different bait types
Obviousness Reasoning
Adapting hook shank flexibility is a known design technique for optimizing bait presentation, representing a routine engineering solution to improve fishing performance
Source Patent Element
Basic fish hook geometry with straight configuration
PTD Variation
Curved bend section designed to reduce fish escape probability
Obviousness Reasoning
Modifying hook geometry to improve fish retention is a well-understood design approach in fishing tackle engineering, involving predictable geometric variations
Source Patent Element
Standard fixed-point fish hook design
PTD Variation
Retractable point element to reduce handling injury risks
Obviousness Reasoning
Implementing safety mechanisms through point retraction represents a standard engineering solution to known user safety concerns in fishing equipment
35 U.S.C. § 103 Summary: Based on the teachings of US Patent 11856919, a Person Having Ordinary Skill In The Art would find the claimed variations in the present technical disclosure to be obvious extensions of the prior art. The proposed modifications represent predictable design alternatives that would be readily conceived by a skilled practitioner without requiring inventive insight, thus rendering potential corresponding patent claims obvious under 35 U.S.C. Section 103.
