Purpose. The patent addresses substitutes for gelatin in oral delivery capsules—i.e., capsule compositions and manufacturing processes that avoid gelatin while still forming capsules.

Plain-language scope (from the supplied text). The excerpt identifies the invention in terms of a composition and a manufacturing process. Recurring components named in the supplied classification/term data include carrageenan, a plasticizer, water, and gel; other substances listed include dextrin, maltodextrin, glycerine/glycerol, sorbitol, gum arabic (acacia), xanthan gum, locust bean gum, gellan gum, mannan, starch, maltitol, lactitol, xylitol, polyvinylpyrrolidone, and various salts, colorants, antioxidants, and diluents. Processing terms appearing include cooling, heat treatment, casting, and sealing—consistent with forming and closing capsule films. The terms "gelatin" (and "gel," "gelatine") recur, reflecting that the disclosed subject matter is defined by its relationship to gelatin-containing capsules.

What the excerpt does not establish. The supplied text omits the actual claim language, the abstract, the written description, and the examples. Therefore this overview cannot state claim limitations, ingredient weight percentages or ratios, the number and scope of claims, the specific manufacturing steps or their order, or the technical advantages asserted over gelatin capsules. It also does not establish validity, enforceability, or the accuracy of any listed assignee or legal-status entry; the source itself notes the legal status and assignee listings are assumptions, not legal conclusions. No litigation, prior-art, or ownership-transfer analysis is provided here.

Assignment history

Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
