Patent Overview — US 9,906,500 B2
Title: Secure data parser method and system
Patent number: US9906500B2
Inventors: Mark S. O'Hare, Rick L. Orsini, Roger S. Davenport
Original assignee: Security First Corp. Current assignee (as listed): Security First Innovations LLC
Key dates: Priority date 2004-10-25; application US14/710,528 filed 2015-05-12; publication US20150261973A1 on 2015-09-17; granted and published as US9906500B2 on 2018-02-27. Anticipated expiration listed as 2025-10-25; legal status listed as "Expired - Fee Related."
Purpose and scope (plain language): The title and prior-art keywords ("data," "authentication," "engine," "user," "shares") indicate a method and system for securely handling data by parsing it into multiple shares and applying authentication measures. The classification entries support this reading, placing the patent in network security for confidential data exchange (H04L63/0428 — protecting data content by encrypting or encapsulating the payload), cryptographic facilities or services (G06F21/602), protecting data (G06F21/60, G06F21/606), and access control to files, objects, or distributed/database systems (G06F21/6218), alongside indexing and structured-data file-system classifications (G06F16/20, G06F16/22). In broad terms, the claimed subject matter concerns splitting data into shares with authentication and access-control features, though the excerpt does not include claim language.
What the excerpt does not establish: It omits the claims, written description, and drawings, so the actual claimed scope cannot be determined from it. It provides no information about embodiments, technical implementation details, or the number and content of claims. Because the instructions bar research into litigation, ownership transfers, validity, and prior art, nothing here should be read as an assessment of those matters. Dates and statuses are stated only as they appear in the source and are assumptions, not legal conclusions, per the source's own disclaimer.

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.
