Claim Text:
1. A gutter cover mountable on a rain gutter, the gutter cover comprising: a porous fiber mat comprising randomly disposed fibers held together by a binding agent; a nonfibrous coating different from and in addition to the binding agent and separate from the binding agent, and overlying and disposed on and between at least a portion of the fibers within the mat adhering to at least a portion of the fibers and the binding agent holding the fibers together, the coating including a stiffening agent, which coats the randomly disposed fibers forming the porous fiber mat, adding rigidity to the randomly disposed fibers and to the porous fiber mat so that the porous fiber mat can be disposed along the top of the rain gutter and spaced from a lower surface of the rain gutter, without a supporting structure joined to the porous fiber mat, the stiffening agent adding sufficient rigidity to the porous fiber mat so that the porous fiber mat is supportable primarily adjacent opposite edges of the porous fiber mat and not primarily along a lower surface of the porous fiber mat between the opposite edges; the porous fiber mat remaining sufficiently porous despite the presence of the stiffening agent within the fiber mat to allow passage of rainwater therethrough into the rain gutter, but preventing passage of solid debris into the rain gutter.
