Patent 12412561

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

  • Andrei Golman: Likely employed by Sanas Ai Inc. at the time of filing. The application was filed by Sanas Ai Inc. on July 31, 2023, and the inventors assigned their interest to Intone Inc. on the same day. The patent was subsequently assigned back to Sanas.ai Inc.
  • Dmitrii Sadykov: Likely employed by Sanas Ai Inc. at the time of filing. The application was filed by Sanas Ai Inc. on July 31, 2023, and the inventors assigned their interest to Intone Inc. on the same day. The patent was subsequently assigned back to Sanas.ai Inc.

No unusual patterns suggesting inventor departure or fire-sale are apparent. The transfers appear to be corporate reassignments.

Original assignee

The "Original Assignee" on the Google Patents record is listed as Sanas Ai Inc. Sanas Ai Inc. develops and provides real-time accent correction technology, which directly embodies the claims of US12412561. The company is currently operating and actively engaged in its primary line of business.

NPE / troll-pattern signals

  1. Shell-entity transfer — unclear. While Intone Inc. briefly held the patent, the lack of correspondent details and product information for Intone Inc. prevents a definitive assessment. However, the subsequent transfer back to Sanas.ai Inc., an operating company, suggests it was not a typical shell transfer for assertion.
  2. Known asserter in the chain — not present. Neither Intone Inc. nor Sanas.ai Inc. are identified as known patent assertion entities (NPEs) based on public lists or the provided information.
  3. Repeat correspondent across the chain — unclear. Correspondent information is not provided in the source text, precluding an assessment.
  4. Cascading transfers — not present. There are only two transfers within the timeline (inventors to Intone, then Intone to Sanas.ai Inc.), which does not constitute cascading transfers indicative of an NPE scheme. Both transfers appear to be part of an initial corporate setup or restructuring.
  5. Pre-litigation transfer — not present. The patent was granted on September 9, 2025. The latest assignment to Sanas.ai Inc. occurred on January 23, 2025, well before the patent was granted. There is no indication of litigation filed against this patent in the provided text.
  6. Bankruptcy fire-sale — not present. There is no information to suggest any assignor in the chain underwent bankruptcy proceedings.
  7. Privateering — not present. No evidence suggests an operating company transferred the patent to an NPE to assert on its behalf.
  8. Defensive aggregator (anti-NPE) — not present. The chain terminates with Sanas.ai Inc., an operating company, not a defensive aggregator.

Verdict

Operating-company assertion

The patent originated from inventors associated with Sanas Ai Inc., an operating company actively developing and commercializing real-time accent correction technology, which directly embodies the claims. The two assignments documented (inventors to Intone Inc., then Intone Inc. to Sanas.ai Inc.) appear to be internal corporate transfers or restructuring events, especially since Sanas.ai Inc. is the ultimate assignee listed as the "Current Assignee" and the technology aligns with their product offerings. There are no clear signals of NPE involvement.
