Microsoft Technology Licensing Assigned Two Patents

Flexible decoding in DNA storage based on redundancy codes
Microsoft Technology Licensing, Inc, Redmond, WA, has been assigned a patent (11495324) developed by Yekhanin, Sergey, and Gopi, Sivakanth, Redmond, WA, for a “flexible decoding in DNA data storage based on redundancy codes.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Data that has been stored according to a DNA data storage method can be decoded using a flexible approach that supports both solitary strand mapping and cluster-based trace reconstruction. Solitary strand mapping can place strings based on integrity verification. Redundancy information can be partitioned to support error correction during the solitary strand mapping while still achieving integrity verification. Clusters with verified strands can be skipped during cluster-based trace reconstruction. Useful for increasing the accuracy of the trace reconstruction procedure.”

The patent application was filed on 2019-10-01 (16/590320).

DNA storage on 2D support material
Microsoft Technology Licensing, lnc., Redmond, WA, has been assigned a patent (11485965) developed by Strauss, Karin, Nguyen, Bichlien Hoang, Seattle, WA, Grass, Robert N., Kohll, Alexander Xavier Christof, and Chen, Weida, Zurich, Switzerland, for a “DNA data storage on two-dimensional support material.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A data storage medium is disclosed comprising a two-dimensional (2D) support structure onto which artificially synthesized DNA molecules encoding digital information are placed and then covered with a protective layer. The 2D support structure is formed from a material such as metal foil, glass, or plastic. The 2D support structure may be functionalized with positively charged molecules to improve DNA adhesion. The DNA is protected from degradation by encapsulation in a protective layer of a non-reactive material such as silica or a thin layer of metal. A process for storing DNA on 2D support structures is also disclosed. Correlation of specific DNA molecules with a physical storage location on a 2D support structure provides geometric addressability for selective access to specific digital information.”

The patent application was filed on 2018-11-02 (16/179330).
