Patent number: 11530304Abstract: A biofabricated material comprising a network of crosslinked collagen fibrils produced from recombinant collagen that contains substantially no 3-hydroxyproline residues is disclosed. This material is composed of collagen which is also a major component of natural leather and is produced by a process of fibrillation of collagen molecules into fibrils, crosslinking the fibrils and lubricating the crosslinked fibrils. Unlike natural leathers, this biofabricated material exhibits non-anisotropic (not directionally dependent) physical properties, for example, a sheet of biofabricated material can have substantially the same elasticity or tensile strength when stretched or stressed in different directions. Unlike natural leather, it has a uniform texture that facilitates uniform uptake of dyes and coatings. Aesthetically, it produces a uniform and consistent grain for ease of manufacturability.Type: GrantFiled: February 15, 2017Date of Patent: December 20, 2022Assignee: MODERN MEADOW, INC.Inventors: Brendan Patrick Purcell, David Thomas Williamson, Lixin Dai, Darryl Miles Cassingham, Stephen M.
