Applied DNA Sciences is on track to be issued with a new US patent that protects its methods of DNA tagging cotton fibres during the ginning process. 

The company has received a Notice of Allowance for US patent application, US 2016/0168781 A1, entitled 'Method and Device for Marking Fibrous Materials,' and expects the patent to be issued in the next few months.

It covers methods of DNA-tagging cotton fibres while they travel through the forced air systems found at cotton gins, and later authenticating the DNA-tagged cotton fibres to prove their provenance and/or authenticity all the way to finished goods. DTS units have tagged more than 300m pounds of cotton to-date.

The allowed claims extend the company's patent protection for its proprietary DNA Transfer System (DTS), a key component of its CertainT platform for cotton, and pave the way for large-scale cotton tagging. 

"Despite the downturn in global economic activity that has impacted the global textile supply chains we serve, supply chain certainty and social responsibility remain fundamental to the textile industry's long-term strategy," says Dr James Hayward, president and CEO of Applied DNA.

"We believe the Covid-19 pandemic has increased consumer awareness of the need for authenticity in such textiles as those used in personal protective equipment. When economic activity within the industry ramps, we believe that our CertainT platform is well-positioned to address the critical issues of traceability and authenticity in our traditional home textiles base, as well as new apparel opportunities currently being explored."

MeiLin Wan, vice president of textiles Sales at Applied DNA, adds: "The key to the CertainT platform for cotton is the ability to cost-effectively tag cotton in very large quantities while concurrently collecting data that informs the supply chain down to each individual bale – the date, time, location of tagging, the type of cotton being tagged, among others – through the use of our DTS to give brand owners the assurance that their cotton, their brand, and their supply chains are secure through to their end-customers."

The DTS can be permanently or temporarily installed in essentially any gin, allowing the company to tag cotton worldwide, with DTS units already installed in the US, Egypt and Australia.
