Patent Overview — US8595717B2
Title: Memory controller that includes support for autorun of software or data
Patent number / application: US8595717B2; Application US12/891,594, filed 2010-09-27; granted 2013-11-26; publication US20110138378A1 published 2011-06-09.
Priority: Priority date listed as 2002-12-12 (stated as an assumption); priority claimed from US10/734,481 with a 2003-12-12 date. Legal status: Expired – Fee Related, adjusted expiration 2024-05-09.
Assignee: Original assignee Flexiworld Technologies, Inc.; current assignee listed as Flexijet Technologies Inc. Later reassignment entries name FLEXIJET TECHNOLOGIES, INC. and FLEXIWORLD TECHNOLOGIES, INC., with assignors William Ho Chang and Christina Ying Liu. Inventors: William Ho Chang and Vinaynathan Viswanathan.
Purpose: The invention "relates to a system and method for utilizing storage media such as flash memory for achieving autorun of an application executable or installer stored on the storage media." It provides autorun functionality to any IC memory device, such as a USB peripheral, having a memory component interfaced to a computing-device interface microcontroller — providing autorun of executables or application installers "without an intermediate hardware-based autorun feature." The interface could be USB; the computing device could be a personal computer. Autorun firmware is embedded into the USB microcontroller and "acts as bridge component translating all commands and interactions between a host PC and the memory component."
Plain-language scope: An IC memory device (e.g., USB memory device, compact flash card, smart card) whose controller firmware automatically runs an executable or installer stored on the device when connected to a host, rather than relying on a separate autorun-equipped drive/dock/reader as in the prior-art CD-ROM arrangement of FIG. 2. Figures describe autorun method flows (FIG. 3), alternative USB configurations (FIGS. 4A–4B), multi-functionality USB peripherals and hubs (FIGS. 5–6), a person-operable slide switch (FIG. 7), and a software-implemented copy protection method (FIG. 8). Classifications span G06F (13/38, 9/445, 12/14, 21/60, 21/78–79) and H04L/H04W security and authentication.
Not established by the excerpt: The full claims are not included, so precise claim scope cannot be stated; omitted text is expressly noted, and details of embodiments, drawings, and any examiner citations are unavailable here. Priority and legal-status entries are flagged as assumptions, not conclusions.

Proceedings on file (0)
All PTAB activity →AIA trial proceedings (IPR / PGR / CBM) filed at the USPTO Patent Trial and Appeal Board against this patent. Sourced from the USPTO Open Data Portal and refreshed every six hours; each proceeding number deep-links to the PTAB E2E docket.
No PTAB proceedings on file. This patent has not been challenged via IPR, PGR, or CBM. The absence is itself a signal — well-asserted patents eventually attract IPRs. The LLM analysis below may surface filings the ODP feed hasn’t indexed yet.
PTAB challenges
AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
Extensions
Patent term adjustments, term extensions, continuations, divisionals, family members, and expiration dates.
Derivative works
Defensive disclosure: derivative variations of each claim designed to render future incremental improvements obvious or non-novel.
