Patent Overview — US11069926B1
Title: "Controlling ongoing battery system usage via parametric linear approximation"
Patent number: US11069926B1
Application number: US16/276,545
Inventor(s): Wolf Kohn; Yanfang Shen
Assignee history (as listed): Originally assigned to Vcritonc Alpha Inc; reassigned to VERITONE ALPHA, INC. (2019-02-14, per the assignment record noted); current assignee listed as GRIDBEYOND LIMITED, with "Vcritonc Alpha Inc" also appearing in the current-assignee field. A 2023-10-26 reassignment to GRIDBEYOND LIMITED from VERITONE ALPHA, INC. is recorded.
Key dates: Priority/filing date 2019-02-14; publication/grant date 2021-07-20; adjusted expiration 2040-01-04. Legal status listed as Active (the source notes legal status and assignee listings are assumptions, not legal conclusions).
Purpose and plain-language scope (from the supplied text): The patent concerns controlling ongoing usage of a battery system. Its distinguishing mechanism, per the title and classification metadata, is a "parametric linear approximation" approach. The classifications place it in battery monitoring and control contexts: monitoring/controlling batteries in electric vehicles (B60L58/10), battery monitoring/control circuits (H02J7/80, H02J7/90), charge/discharge regulation responsive to non-electrical parameters such as temperature (H02J7/971, H02J7/975), and smart-battery/condition-measurement arrangements (H01M10/4257, H01M10/48, H01M10/486). Prior-art keywords listed are battery, control, operations, time period, and model.
What the excerpt does not establish:
- No claim language is reproduced, so the actual metes and bounds of the claimed invention are not shown.
- No abstract, detailed description, or drawing content is included; the specific mathematical form of the "parametric linear approximation" is not described.
- No prior-art references are identified, and nothing about validity, infringement, or litigation is established.
- No foreign counterparts, continuation data, or inventor affiliations are provided.
- The excerpt alone does not confirm which assignee entry is operative or explain the "Vcritonc Alpha Inc" listing alongside GRIDBEYOND LIMITED.

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.
