Field of Art

Advanced Manufacturing and Photolithographic Fabrication, specifically focused on three-dimensional metallisation techniques involving enamel underlayers and photosensitive resin patterning

Person of Ordinary Skill (PHOSITA) Profile

A skilled practitioner with expertise in materials science, photolithography, additive manufacturing, and precision fabrication techniques, possessing knowledge of resin chemistry, metallisation processes, and substrate preparation methods

Obviousness Rationale

A PHOSITA would recognize that the source patent's core method of creating three-dimensional metallised patterns can be readily adapted to multiple specialized domains by applying standard design translation principles. The fundamental technical approach of substrate preparation, enamel patterning, photosensitive resin deposition, and selective metallisation remains consistent across different applications. The variations disclosed represent predictable extensions of the original manufacturing technique into domain-specific contexts.
