Here is a concise summary of US patent 12110089:

US Patent Number: 12110089

Title: Sail structure

Assignee: Team New Zealand Ltd

Inventors: Stephen James COLLIE

Filing Date: 2023-06-16

Issue Date: 2024-10-08

Abstract:
Disclosed is a sail comprising a head, a tack, and a luff extending between the head and the tack; a luff region extending along the luff; wherein the luff region has a significantly higher degree of elasticity compared to the average elasticity of a remainder of the sail. Also disclosed is a method of making a sail comprising laying out material to form the sail; arranging material in a luff region of the sail and in the remainder of the sail such that in the direction of the luff, the luff region has a higher degree of elasticity compared to the remainder of the sail; curing or sewing the sail to form a cohesive structure.

Plain-Language Overview of Independent Claims:

• Claim 1: This claim describes a sail with a head, tack, and a luff (leading edge). A "luff region" runs along this leading edge and is significantly more elastic than the rest of the sail ("remainder"). Specifically, the luff region uses a "first material," and the rest of the sail uses at least a "second material," where these materials are different. The key characteristic is that the average stiffness of the second material (in the remainder of the sail) is 2 to 20 times higher than the average stiffness of the first material (in the luff region).

• Claim 23: This claim also describes a sail with a head, tack, luff, and a luff region that is more elastic than the remainder of the sail. It specifies that in the direction of the luff, the stiffness of the regions outside the luff region (i.e., the remainder of the sail) is 2 to 25 times greater than the stiffness of the l luff region.

CAFC 2026 Dockets:
A review of the U.S. Court of Appeals for the Federal Circuit's scheduled cases for April, May, and June 2026 does not explicitly list US patent 12110089. While the CAFC website provides access to case information, filings, records, opinions, and orders, a detailed search of all docket entries or a PACER database search was not conducted within the scope of this request. Therefore, there is no authoritative information to confirm or deny active litigation or other proceedings involving US12110089 in CAFC dockets for 2026 beyond the publicly scheduled argument lists. It is noted that a PTAB case (PGR2025-00062) was filed related to this patent on 2025-08-19, initiated by North Sails Group, LLC, North Technology Group, LLC, and Oakley Capital Investments, but this is a PTAB (Patent Trial and Appeal Board) action, not a CAFC docket entry.
