Title: Shoe having knit wingtip upper

Assignee: Cole Haan LLC

Inventors: Jack Boys, Ann Bono, Aubert Shepherd, Mattias Verfl

Filing Date: May 13, 2019

Issue Date: October 15, 2019

Abstract: A shoe includes a knit upper and a sole secured to the upper. The knit upper has a wingtip pattern knit into the knit upper.

Plain-Language Overview of Independent Claims:

• Claim 1 (Apparatus Claim - Shoe): This claim describes a shoe with a knit upper and a sole. The key feature is the knit upper being a unitary one-piece construction with various seamlessly knitted regions (heel, midfoot, metatarsal, ball, and toe regions). It further specifies that a wingtip pattern is incorporated into the knitted element, and this pattern includes a boundary line formed by two different types of knit structures. This boundary line has converging wing-shaped curved medial and lateral portions.

• Claim 13 (Apparatus Claim - Shoe): Similar to Claim 1, this claim also describes a shoe with a knit upper and a sole. However, it focuses on the knitted element comprising a knitted upper metatarsal region, lateral and medial ball regions, and a toe region. Like Claim 1, it emphasizes the unitary one-piece construction and seamlessly knitted regions, with a wingtip pattern comprising a boundary line made of two different knit structures, where the medial and lateral boundary lines are wing-shaped and curved, with rearwardly converging central portions. This claim appears to be a slightly narrower version of Claim 1 by omitting the heel and midfoot regions from the main list of knitted elements, though they are still implicitly part of an upper.

• Claim 18 (Method Claim - Manufacturing an Upper): This claim outlines a method for manufacturing a shoe upper. The core of the method is knitting with a knitting machine to form a unitary one-piece knitted element. This knitted element includes seamlessly integrated heel, midfoot, metatarsal, ball, and toe regions. A wingtip pattern, defined by a boundary line between two different knit structures, is seamlessly knitted into the element, with the boundary line having converging wing-shaped medial and lateral portions. The first and second knit areas and the wingtip pattern are all seamlessly knitted during the knitting step.

• Claim 21 (Method Claim - Manufacturing an Article of Footwear): This claim details a method for manufacturing an entire article of footwear (shoe with upper and sole). It involves the same knitting process as Claim 18 for creating the unitary one-piece knit upper with seamlessly integrated regions. Specifically, it states that the first knit area is a jersey stitch knit, and the second area is a pointelle stitch knit. The first area is at least in the upper toe region, and the second area is at least in the upper lateral and medial metatarsal regions, with a defined boundary line. After knitting the upper, the method includes attaching the sole to the upper.
