Cambrios Film Solutions reports that it has more than 15 years of fundamental research and development of silver nanowires for mass production, with a strong commitment to IP protection from the beginning.
According to Cambrios CTO Dr. Mike Spaid, Cambrios is now well-positioned with a global patent portfolio of more than 170 issued patents, representing the majority of patent issuances in the space. Cambrios patents cover innovations from silver nanowire synthesis and ink formulation to coated transparent conductors and sensor films. Key US patents in the portfolio have undergone rigorous validity verification by a top-tier US law firm, the company added.
Silver nanowire technology, noted Spaid, has wide applicability for use in projected capacitive touch sensors for consumer and commercial applications. Silver nanowire conductive films are available for use in curved and flat sensors for mobile platforms, and personal computing. The technology is also applicable for large format touch sensors for electronic displays and digital whiteboards.
Two of the newly issued patents are of particular significance: US Patent No. 10026518 titled “Low-haze transparent conductors” issued on July 17, 2018; and Japanese Patent No. 6389856 titled “Ink composition, and a method for manufacturing a transparent conductor” issued on Sept. 12, 2018.
These patents cover new generations of Cambrios’ ClearOhm inks and transparent conductors having an ultra-low added haze of less than 0.5%, a key performance metric affecting display contrast ratio and color performance.
“These recently issued patents cover a key application of our core technology and strengthen our intellectual property protection,” said Spaid. “We have consistently sought to protect, expand and improve uses of our silver nanowire technology in the US and globally. Cambrios Film Solutions invests substantially in research and development to provide the highest quality, most reliable silver nanowire solutions to its customers. Cambrios Film Solutions will defend its intellectual property against unauthorized use by silver nanowire ink manufacturers, silver nanowire film manufacturers, sensor makers or original equipment manufacturers.”
