Hossein Tabatabaei, Yuan; Yongbo, Ma; Jian, Urbana, IL, and Zhao; Huimin, Champaign, IL, for a “re-writable DNA-based digital storage with random access.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The disclosure relates to a re-writable DNA-based digital storage system with a random access feature. An example embodiment includes reading a physical nucleotide sequence of 2n+L bases to form a digital representation of the physical nucleotide sequence; dividing the digital representation of the physical nucleotide sequence into an address representation of n bases, followed by a data representation of L bases, followed by a further address representation of n bases; decoding the data representation into an integer value less than 3L that is a sum of a first addend and a second addend, wherein the data representation includes a first subsequence of bases encoding the first addend followed by a second subsequence of bases encoding the second addend; and storing, in a computer memory, the integer value.”

The patent application was filed on 2019-10-15 (16/653564).
