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.
Inventors
The sole inventor is Mary Anne Fletcher. No employer at the time of filing is listed in the provided documents. The patent was assigned by the inventor to Weple IP Holdings LLC on the same day the application was filed, which is a common practice.
Original assignee
The original and current assignee of record is Weple IP Holdings LLC. The name "IP Holdings LLC" suggests a non-practicing entity (NPE) created for the purpose of holding and monetizing intellectual property rather than producing goods or services. Public records indicate Weple IP Holdings LLC is actively involved in patent litigation, asserting patents from this family against operating companies. There is no evidence that the assignee has ever shipped a product embodying the claims.

NPE / troll-pattern signals
Shell-entity transfer — Present. The patent was transferred on the day of its filing from the inventor directly to Weple IP Holdings LLC. The assignee name, a "Holdings LLC," is characteristic of a non-practicing entity established for licensing or litigation rather than product development (Reel 069635/0670).
Known asserter in the chain — Present. The assignee, Weple IP Holdings LLC, is a known patent asserter. It is listed as the plaintiff in litigation against T-Mobile (case 2:24-cv-01316, Western District of Washington) involving a related patent from the same family, as documented by Unified Patents.
Repeat correspondent across the chain — Not present. Only one assignment is on record, so there is no recurrence of the correspondent, Robert P. Lord.
Cascading transfers — Not present. There is only a single recorded assignment from the inventor to the current assignee.
Pre-litigation transfer — Present. The assignment to Weple IP Holdings LLC was executed on 2024-01-25. While this patent (issued 2024-10-08) has not yet been asserted, a sibling patent from the same family was asserted in litigation filed on 2024-09-11. The initial transfer to the holding company was a foundational step taken in the same year that litigation began, indicating a strategy of monetization through assertion from the outset.
Bankruptcy fire-sale — Not present. There is no indication of bankruptcy proceedings.
Privateering — Not present. There is no evidence of an operating company transferring the patent to be asserted on its behalf.
Defensive aggregator (anti-NPE) — Not present. The chain does not involve any known defensive aggregators.
Verdict
NPE — high confidence
The assignee, Weple IP Holdings LLC, is a non-practicing entity with "IP Holdings" in its name, and it received the patent directly from the inventor at the time of filing (Reel 069635/0670). This same entity is confirmed by Unified Patents to be actively litigating other patents from the same family within months of this patent's application, establishing a clear pattern of assertion. The combination of a shell-like holding company structure and active litigation provides high confidence in its status as an NPE.
