Patents by Inventor Jonathan Buchanan

Jonathan Buchanan 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: 20240192221
    Abstract: The invention describes methods and reagents useful for sequencing polypeptide molecules. The method comprises affixing a polypeptide to a substrate and contacting the polypeptide with a plurality of probes that selectively bind to a terminal amino acid or a terminal amino acid derivative. Probes bound to the polypeptide molecule are then identified before cleaving the terminal amino acid or terminal amino acid derivative of the polypeptide. Also provided are probe compositions comprising (a) a ClpS variant comprising at least 80% sequence identity to SEQ ID NO: 1, wherein the ClpS variant binds to an N-terminal amino acid or a N-terminal amino acid derivative with a different selectivity than a wild-type ClpS; and (b) a detectable label.

  • Patent number: 11802878
    Abstract: The invention describes methods and reagents useful for sequencing polypeptide molecules. The method comprises affixing a polypeptide to a substrate and contacting the polypeptide with a plurality of probes. Each probe selectively binds to an N-terminal amino acid or an N-terminal amino acid derivative. Probes bound to the polypeptide molecule are then identified before cleaving the N-terminal amino acid or N-terminal amino acid derivative of the polypeptide. Also provided are methods for the sequencing a plurality of polypeptide molecules in a sample and probes specific for N-terminal amino acids or N-terminal amino acid derivatives.

  • Patent number: 10109266
    Abstract: In the present invention, a user is capable of choosing manually or automatically a point on a chosen keyboard where a division will occur. For musical/artistic reasons, this point must regularly change. To accommodate this need, the user can store that location in an existing preset/restore system and recall it upon demand with other settings.

  • Publication number: 20070143200
    Abstract: A preferred embodiment of the subject invention is directed to creation and pricing of an option related to a target zone in a time-price plot. If the price curve against time enters this zone (in a preferred embodiment, a “box”), a fixed amount of money is paid to the owner of the option; if the curve misses the box, there is no payout to the option owner, who also forfeits the premium paid for the option. Software is described that enables an option buyer to easily create and set the parameters of such an option, that computes a premium for the option, and that manages payout and other functions related to the option. The above-described embodiment is a buy-to-hit option. Other embodiments are directed to sell-to-hit, buy-to-miss, and sell-to-miss options.
