“We take great pride in the patenting of our SigNature T molecular tags, providing us with broad long-term market exclusivity. In addition, the patenting of our MMR device paves the way for the instant authentication of a broad range of taggants and exciting licensing opportunities,” said Dr James Hayward, president and CEO of Applied DNA. 

“Protecting our innovations has always been a cornerstone of Applied DNA. Our robust intellectual property portfolio is more important than ever, as industry awareness and acceptance of our technologies is rapidly growing.”

SigNature T molecular tags

The '538 patent, issued on 17 October, protects the core technology powering Applied DNA's SigNature T molecular tags in the textiles industry and is directed at methods of enhancing the binding affinity of molecular tags to a variety of textile substrates, including cotton, wool, cellulosic materials and man-made fibres.

The enhanced binding affinity of the SigNature T molecular tags enables them to survive extremely harsh manufacturing processes, such as those found in leather, cotton and synthetics manufacturing. The patented methods are currently used in wide range of SigNature T applications, and are integral to the company's pursuit of a global textiles industry anticipated to grow to US$ 910 billion in sales in 2019 from US$ 750 billion in 2015.

The issuance of the '538 patent raises Applied DNA's patent portfolio to 53, in addition to over 70 pending applications.

MMR device

The '454 Application, allowed on October 26, 2017 will issue as a patent, and protects Applied DNA's proprietary Multimode Image and Spectral Reader (MMR) device that provides for instant detection and identification of a wide variety of optical, molecular, olfactory and radio based taggants through the use of electronic sensor capture and digital database analysis.

The handheld MMR device can rapidly detect one or more taggants and compare the detected taggants to library of known taggant configurations to provide instant authentication.
