Cambrios Files Inter Partes Review Seeking to Invalidate C3Nano Inc.’s Core US Patent in Silver Nanowire (SNW) Film Technology

World News: . []

SUNNYVALE, Calif., Feb. 11, 2019 (GLOBE NEWSWIRE) -- Cambrios Film Solutions Corporation, the world leader in SNW technology and owner of the most comprehensive portfolio of SNW related patents, filed a petition requesting an inter partes review (IPR) of C3Nano’s core US Patent 9,183,968 with the US Patent Trial and Appeal Board on February 1, 2019.

The petition alleges that the claims in C3Nano’s ‘968 patent are invalid and challenges C3Nano’s assertion that its “fusion technology” is not covered by existing prior art. Cambrios argues in its petition that SNW transparent conductive films exceeding the electrical and optical performance described in the ‘968 were reduced to practice, commercially available, and integrated into display products sold worldwide years prior to the C3Nano filing of the ‘968 patent. This proceeding is part of an ongoing global effort in China and the United States by Cambrios to defend its portfolio of SNW related patents and to challenge the validity of patents owned by other market participants that claim old and previously known technology.

Cambrios uses its SNW technology to deliver unique transparent conductive film products to the market for the next generation of displays and touch screens. Cambrios provides total product solutions to its customers seeking to replace indium tin oxide (ITO) based touch sensors with a lower cost and higher performing alternative. The ultra-low sheet resistance of SNW film makes it the material of choice for ultra-large area touch applications such as interactive whiteboards, public signage, and touch TVs. In addition, the unique mechanical properties of SNW film enable the commercial reality of rapidly emerging display devices such as flexible, foldable, and stretchable phones and tablets.

Cambrios strives to continuously provide its customers with the most innovative materials and solutions for their products. As the pioneer in the development and commercialization of SNW technology, Cambrios’ seminal patents broadly cover SNW synthesis methods, ink formulations, films, and devices. “Cambrios is committed to protect its investment of more than a decade of R&D innovation in SNW technology and will vigorously defend its intellectual property rights if infringed,” said Dr. Michael Spaid, Chief Technology Officer at Cambrios.
