Iridia Assigned Three Patents

Writing and reading data stored in polymer using nano-channels
Iridia, Inc., Carlsbad, CA, has been assigned a patent (11545213) developed by Predki, Paul F., Carlsbad, CA, for “systems and methods for writing and reading data stored in a polymer using nano-channels.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The disclosure provides a novel system and method of storing multi-bit information, including providing a nano-channel-based polymer memory device, the device having at least one memory cell comprising at least two addition nano-channels, each of the addition nano-channels arranged to add a unique chemical construct (or codes) to the polymer when the polymer enters the respective addition nano-channel, the polymer having a bead or origami on a non-writing end of the polymer, each nano-channel having a nano-port constriction having a port width which allows the polymer to pass through the nano-port, and does not allow the bead or origami to pass through and does not allow addition or deblocking enzymes (or beads attached thereto) to pass through the nano-port, successively steering the polymer through the nanopore into the addition nano-channels to add the codes to the polymer based on a predetermined digital data pattern to create the digital data pattern on the polymer.”

The patent application was filed on 2021-08-06 (17/396439).

Synthesizing DNA
Iridia, Inc., Carlsbad, CA, has been assigned a patent (11505825) developed by Predki, Paul F., Carlsbad, CA, for “Methods of synthesizing DNA.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The disclosure provides methods of synthesizing DNA using topoisomerase-mediated ligation, by adding single nucleotides or oligomers to a DNA strand in the 3′ to 5′ direction.”

The patent application was filed on 2021-04-16 (17/233186).

Writing and reading data stored in polymer
Iridia, Inc., Carlsbad, CA, has been assigned a patent (11152061) 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 2020-05-04 (16/866364).
