mPhase Technologies, Inc. reported that it has received a Notice of Allowance from the U.S. Patent & Trademark Office of a Key Smart Surface Patent. The invention is a key patent for mPhase Technologies in its continuing efforts to protect the company's intellectual property related to smart surfaces. The invention relates to a single porous substrate formed from a network of filaments wherein the network of filaments is comprised of a first plurality of filaments and a second plurality of filaments is exposed to a surface modification treatment and the second plurality of filaments is covered with a conformal coating.

A wetting region comprised of the first plurality of filaments extends through a first portion of the porous substrate and is permeable to fluid transport and a non-wetting region comprised of the second plurality of filaments which is operable to switch between a wetting and non-wetting state by an electrical source coupled to the second plurality of filaments. The invention protects a porous substrate with integrated wetting and non-wetting regions and is a key patent win for mPhase Technologies.
