Iridia Assigned Patent

Iridia, Inc., Carlsbad, CA, has been assigned a patent (11923004) developed by Predki, Paul F., Carlsbad, CA, and Foster, John Stuart, New Orleans, LA, for “systems and methods for writing and reading data stored in a polymer.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A system and method of storing and reading digital data, including providing a nanopore polymer memory (NPM) device having at least one memory cell comprising at least two addition chambers each arranged to add a unique chemical construct (or codes) to a polymer (or DNA) string when the polymer enters the respective addition chamber, the data comprising a series of codes, successively steering the polymer from deblock chambers through the nanopore into the addition chambers to add codes to the polymer to create the digital data pattern on the polymer, and accurately controlling the bit rate of the polymer using a servo controller. The device may have loading chamber(s) to load (or remove) the polymer into/from the deblock chambers through at least one “micro-hole”. The cell may be part of a memory system that stores and retrieves “raw” data and allows for remote retrieval and conversion. The cell may store multi-bit data having a plurality of states for the codes.”

The patent application was filed on 2023-02-17 (18/171106).
