Idaho Patent of the Month – January 2025
RxFiber has revolutionized the biomedical textile industry with its groundbreaking high-tenacity polyethylene terephthalate (HT PET) fiber. This innovation addresses a critical challenge in the medical field—ensuring long-term stability and durability of implantable bio-textile devices. Traditional polyester fibers, while approved for medical applications, have been found to degrade over time, leading to loss of strength and potential surgical complications. RxFiber’s advanced HT PET fiber significantly improves the longevity and reliability of these essential medical materials.
By refining the PET extrusion process, RxFiber has developed a fiber with unmatched mechanical properties. The fiber boasts a denier per filament of less than 1.5 dpf and a tenacity of 7.0 to 9.0 gram-force per denier, making it considerably stronger than conventional options. The manufacturing method ensures purity by eliminating colorants and titanium dioxide, which could compromise biocompatibility. Additionally, the selection of PET polymers with precise viscosity control enhances the fiber’s resilience in biological environments.
This innovation has direct applications in life-saving medical devices such as sutures, vascular grafts, and implantable meshes. The enhanced strength of the HT PET fiber translates into improved surgical outcomes by maintaining stitch density and structural integrity over extended periods. As patient lifespans increase, the need for more durable biomaterials becomes imperative, and RxFiber’s invention marks a significant step forward in medical textile technology. With its high-performance properties, this fiber is set to redefine the standards of durability and reliability in the biomedical sector.

What is the R&D Tax Credit?
The Research & Experimentation Tax Credit (or R&D Tax Credit), is a general business tax credit under Internal Revenue Code section 41 for companies that incur research and development (R&D) costs in the United States. The credits are a tax incentive for performing qualified research in the United States, resulting in a credit to a tax return. For the first three years of R&D claims, 6% of the total qualified research expenses (QRE) form the gross credit. In the 4th year of claims and beyond, a base amount is calculated, and an adjusted expense line is multiplied times 14%. Click here to learn more.
