Assignment history

Inventors

• Andrei Golman: Likely Intone Inc. (assigned patent to Intone Inc. on filing date)
• Dmitrii Sadykov: Likely Intone Inc. (assigned patent to Intone Inc. on filing date)

Both inventors assigned their interest to Intone Inc. on the filing date of the application (December 19, 2022), which is a common practice for employees assigning intellectual property to their employer.

Original assignee

The original assignee named on the patent application filing was Intone Inc.

It is unclear whether Intone Inc. shipped a product embodying the claims. The patent details a technology for real-time accent correction in speech audio signals. Intone Inc. later assigned the patent to Sanas.ai Inc., which is active in this field. This suggests Intone Inc. may have been a startup or entity that developed the core technology.

Intone Inc.'s primary line of business, as inferred from the patent, was related to speech audio processing technology, particularly real-time accent correction.

Intone Inc. is no longer the assignee of record, having assigned the patent to Sanas.ai Inc. Its current operational status (operating, dissolved, acquired, etc.) is not determinable from the patent text alone, but the assignments suggest a transfer of assets.

Assignment timeline

Due to the inability to access the live USPTO Patent Assignment Search database at assignmentcenter.uspto.gov, the following assignment timeline is constructed using the "Legal status" -> "reassignment" events listed on Google Patents for US11715457. This means critical information such as specific reel/frame numbers and the correspondent of record (attorney/firm who filed the recording), which are essential for identifying NPE patterns, cannot be provided.

NPE / troll-pattern signals

1. Shell-entity transfer — Unclear. Without correspondent addresses and more detailed corporate information for Intone Inc., it's not possible to determine if it was a shell entity. Sanas.ai Inc. appears to be an operating company based on its public profile.
2. Known asserter in the chain — Not present. Neither Intone Inc. nor Sanas.ai Inc. appear on common public NPE lists.
3. Repeat correspondent across the chain — Unclear. This information is not available from the Google Patents legal events. Access to the USPTO Assignment Center records is required to identify correspondents.
4. Cascading transfers — Not present. There are two assignments from Intone Inc. to Sanas.ai Inc. in 2025, but they are spaced several months apart, and without correspondent information, it's not possible to determine if they are "cascading" in a way indicative of an NPE pattern.
5. Pre-litigation transfer — Unclear. The first district court litigation (3:25-cv-05666) was filed in 2025. The patent was assigned to Sanas.ai Inc. on 2025-01-16 and 2025-06-06. If the litigation was filed later in 2025, it could indicate a pre-litigation transfer. However, without a precise litigation filing date, it is unclear if the transfer dates fall within 6 months before the first infringement suit.
6. Bankruptcy fire-sale — Not present. There is no indication in the patent records or available information that Intone Inc. or Sanas.ai Inc. underwent bankruptcy proceedings leading to the patent transfer.
7. Privateering — Not present. No evidence suggests an operating company transferred the patent to an NPE for assertion on its behalf. Sanas.ai Inc. is the current assignee and appears to be an operating company.
8. Defensive aggregator (anti-NPE) — Not present. The chain does not terminate at a known defensive aggregator like RPX or AST.

Verdict

Insufficient data

The lack of access to the USPTO Assignment Center records means critical information, particularly correspondent details and precise recording dates, is missing. This prevents a thorough analysis of NPE signals such as shell-entity transfers and repeat correspondents. While the current assignee, Sanas.ai Inc., appears to be an operating company, the absence of full assignment data makes a confident determination of NPE patterns impossible at this time.
