Purpose and plain-language scope
The patent is titled "Secure data parser method and system." The supplied text identifies the field through its prior-art keywords—data, authentication, engine, user, and cryptographic—indicating a method and system concerning cryptographic handling, authentication, and parsing of data by an engine in connection with a user.
The text does not include the abstract, claims, or written description, so the specific steps, components, and scope of the invention cannot be stated from this excerpt. What can be said is limited to the bibliographic and procedural record: the application was filed in 2018 claiming priority to 2004-10-25, was granted as US11178116B2 on 2021-11-16, and lists a family continuation relationship to US11968186B2 (priority to US17/111,262, 2020-12-03) and US12381857B2 (priority to US18/131,229, 2023-04-05). An earlier publication, US20180367509A1, published 2018-12-20.
What the excerpt does not establish
This overview relies solely on the supplied Google Patents excerpt and the source URL above. The excerpt contains no claim text, abstract, or detailed description, so it does not establish the actual claimed invention, its limitations, or its plain-language operation beyond the title and keyword fields. It also does not establish validity, enforceability, claim scope, or the accuracy of any assignment or legal-status listing; the source itself notes that legal status and assignee listings are assumptions and not legal conclusions.
Per the operating rules, no litigation, ownership-transfer, validity, or prior-art research has been performed, and no missing facts have been inferred.

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.
