Patent 8621627

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.

NPE / troll-pattern signals

  1. Shell-entity transfer — not present. The patent has consistently been assigned to and from Chelsio Communications Inc. and various banks for security interests. Chelsio is an operating company.
  2. Known asserter in the chain — not present. Neither Chelsio Communications Inc. nor any of the banks appear on public NPE lists.
  3. Repeat correspondent across the chain — present. David J. Pierre of Rutan & Tucker LLP is the correspondent on multiple security interest and release filings from 2014 to 2025 (Reel 032479/0089, Reel 033989/0930, Reel 033990/0451, Reel 039360/0596, Reel 039296/0550, Reel 042142/0232, Reel 050050/0396, Reel 050112/0234, Reel 073264/0525). This recurrence is a strong indicator of a consistent legal representative for Chelsio's patent-related financial transactions.
  4. Cascading transfers — not present. The transfers primarily involve Chelsio Communications Inc. and various banks in a securitization context, not rapid transfers between shell entities.
  5. Pre-litigation transfer — unclear. The latest assignment (a release back to Chelsio) was recorded on 2025-12-18 (executed 2024-01-22), while Speednic LLC v. Nvidia Corp et al. was filed on April 16, 2026. This is a period of roughly 4 months between the last recorded transfer and the litigation filing. However, the last actual transfer of ownership was the release back to Chelsio, which means Chelsio owned the patent leading up to the Speednic litigation. If Speednic LLC is an NPE, then the patent could have been transferred to Speednic shortly before the litigation, but this transfer is not yet publicly recorded.
  6. Bankruptcy fire-sale — not present. There is no indication in the assignment records or general knowledge that Chelsio Communications Inc. has undergone bankruptcy proceedings that resulted in a patent sale.
  7. Privateering — not present. There is no evidence to suggest Chelsio Communications Inc. transferred this patent to an NPE to assert on their behalf.
  8. Defensive aggregator (anti-NPE) — not present. The chain does not terminate at a known defensive aggregator.

Verdict

Insufficient data to definitively declare NPE status. While there is current litigation in Speednic LLC v. Nvidia Corp et al., the assignment records available via USPTO Assignment Center (as of 2026-05-30) do not show a transfer from Chelsio Communications Inc. to Speednic LLC. All recorded assignments reflect security interests and releases, with Chelsio Communications Inc. consistently remaining the assignee. Without a recorded transfer to Speednic LLC or further evidence regarding Speednic LLC's nature, a high-confidence NPE verdict is not warranted based solely on the assignment chain.
