Board of Trustees of University of Illinois Assigned Patent

The Board of Trustees of the University of Illinois, Urbana, IL, has been assigned a patent (10,566,077) developed by Milenkovic, Olgica, Yazdi, S. M. 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 selecting address representations of m nucleotide sequences of n bases each. Each of the address representations of m nucleotide sequences, (i) consists of approximately 50% guanine and cytosine content and, (ii) is self-uncorrelated. The address representations are mutually uncorrelated with one another. All of the address representations end with a particular base. The embodiment also includes selecting, for a particular address representation from the address representations of the m nucleotide sequences, a corresponding data representation of a nucleotide sequence of L bases. The embodiment further includes concatenating the particular address representation with the data representation to form a representation of a target nucleotide sequence of n+L bases. In addition, the embodiment includes synthesizing the target nucleotide sequence.”

The patent application was filed on November 18, 2016 (15/356,118).
