Patent 7826350

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 owned by Chelsio Communications, Inc., an operating company. The recorded transfers are all security agreements and their subsequent releases with financial institutions, not transfers of title to shell entities.
  2. Known asserter in the chain — Not present. The assignees involved in security agreements (East West Bank, Silicon Valley Bank, Novirian Capital, Western Alliance Bank) are all financial institutions, not known patent assertion entities.
  3. Repeat correspondent across the chain — Present. K&L Gates LLP, through attorneys Michael T. Novirian and Dennis K. Chung, is listed as the correspondent for several security agreements and releases (Reel 033333/0859, Reel 033333/0861, Reel 037989/0984, Reel 038096/0200, Reel 040715/0746). This indicates consistent legal representation for Chelsio Communications, Inc.'s financing activities.
  4. Cascading transfers — Not present. While there are multiple security agreements, they do not represent transfers of ownership between chained LLCs in quick succession.
  5. Pre-litigation transfer — Not present. No litigation involving US 7,826,350 has been found as of May 27, 2026.
  6. Bankruptcy fire-sale — Not present. Chelsio Communications, Inc. remains an active operating company.
  7. Privateering — Not present. There is no evidence in the assignment records or public information suggesting Chelsio Communications, Inc. has transferred the patent to an NPE to assert on its behalf.
  8. Defensive aggregator (anti-NPE) — Not present. The ownership chain does not terminate at a defensive aggregator.

Verdict

Operating-company assertion.

The patent US 7,826,350 is currently owned by its original assignee, Chelsio Communications Inc., which is an active operating company that manufactures products directly embodying the claimed invention. The recorded assignments solely reflect security interests granted to financial institutions and their subsequent releases (e.g., Reel 030068/0805 executed 2013-04-29, Reel 033333/0861 executed 2014-10-14, Reel 046340/0396 executed 2019-08-14). While the definition of "Operating-company assertion" includes "and is suing actual competitors," no litigation involving this patent has been identified in publicly available records, presenting a minor contradiction with the strict definition; however, the ownership pattern strongly indicates an operating company holds the patent for its core business rather than for assertion by an NPE.
