Patents by Inventor Justin Whitfield

Justin Whitfield has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11525080
    Abstract: Compounds are identified that act as crystallization suppressants when added to clear brine fluids, significantly lowering the true crystallization temperatures of the brines, and allowing for higher salt content in clear brine fluids. The crystallization suppressants of the invention also allow for the preparation of higher density zinc free brines. Crystallization suppressant blends are also identified that allow for the preparation of high density clear brine fluids with lower viscosities.

  • Patent number: 11427673
    Abstract: The present invention provides compositions comprising the reaction product of an aliphatic diisocyanate, and a reactive intermediate made from one selected from the group consisting of oxazolidinones, benzoic sulfimides (saccharins), 1H-indole-2,3-diones (isatins), succinamides, N-hydroxysuccinamides, 4-hydroxy-3-methoxybenzaldehydes (vanillins), ?-ketoamides, piperazines, benzofuranones, 3,4-dihydroxycyclobut-3-ene-1,2-diones (squaric acids), squaric acid esters, ?-ketoamides, anilines, and ?-ketoamide, phenols. The aliphatic diisocyanate comprises one selected from the group consisting of isocyanurates, biurets, iminooxadiazine diones, urethanes, uretdiones, carbodiimides, and allophanates. The resulting compositions may be useful in producing coatings, adhesives, sealants, castings, composites and films having durability, color stability, high gloss, and chemical resistance properties similar to those made from polyurethane.

  • Publication number: 20210015121
    Abstract: Provided herein is a composition comprising a deliverable substance in a matrix for controlled delivery. The composition comprises cellulose micro fibers (“CMF”), an inert particle substance, and a deliverable substance. This general formula may be applied to a wide range of products, as discussed in detail below. For example, described herein are dog treat compositions comprising cellulose micro fibers which are a substitute for rawhide dog chews. Dog treats made as described herein are very durable and have a wide spectrum of possible sizes, flavors and properties.
