Section 103 Obviousness Analysis (PHOSITA)

▼

Field of Art

Polymer film and laminate packaging technologies, specifically focusing on polyethylene-based multilayer film structures with barrier adhesive layers for flexible packaging applications

Person of Ordinary Skill (PHOSITA) Profile

A materials engineer or packaging specialist with expertise in polymer science, adhesive technologies, and film manufacturing, possessing knowledge of polyethylene compositions, lamination techniques, and barrier layer design

Obviousness Rationale

A person having ordinary skill in the art would recognize that the PTD's disclosed variations represent predictable extensions of the source patent's core technical approach. The fundamental architecture of an all-polyethylene laminate film structure remains consistent, with the PTD introducing incremental modifications that would be apparent to a skilled practitioner. These variations demonstrate standard design optimization techniques within the established technical framework of the original patent.
