Patents by Inventor Paul ROTHWELL

Paul ROTHWELL has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20230272461
    Abstract: The present invention relates to improved processes for production of closed linear deoxyribonucleic acid (DNA), in particular cell-free enzymatic production of closed linear DNA molecules, preferable using a closed linear DNA as a template for DNA synthesis. The invention further relates to a novel closed linear DNA species, suitable for use as a template in the improved processes for production of closed linear DNA. Further, the invention pertains to the intermediate products of the processes, since this enables the production of larger quantities of closed linear DNA from the template than with methods known in the art.

  • Publication number: 20230091493
    Abstract: The present invention relates to an improved process for synthesis of deoxyribonucleic acid (DNA), in particular cell-free enzymatic synthesis of DNA, preferably on a large or industrial scale, with an improved yield and/or with an improved efficiency. The invention requires the use of nucleotide complexes wherein the nucleotide is associated with a mixture of divalent and monovalent cations. Preferably, the divalent cation may be magnesium or manganese.

  • Publication number: 20220333129
    Abstract: The invention relates to a delivery vector for the delivery of a single-stranded nucleic acid. Said vector is a closed circular polynucleotide comprised of at least three sections, two of which have sufficient complementarity to form a duplex, and an intervening sequence containing the single-stranded nucleic acid to be delivered. Said duplex includes a recognition sequence for a targeted nuclease such that under appropriate conditions the single-stranded nucleic acid is released.

  • Patent number: 10501782
    Abstract: The present invention relates to an improved process for synthesis of DNA, RNA, proteins and like molecules, in particular cell-free enzymatic synthesis of DNA, preferably in large scale. The present invention relates to the synthesis of DNA using strand-displacement replication and the addition of nucleotides to the reaction mixture is controlled, thus controlling yield. The reaction mixture contains a starting amount of nucleotides, polymerase and DNA template, to which further nucleotides are supplied in a controlled manner.
