NPE / troll-pattern signals

1. Shell-entity transfer — Not present. The patent has consistently been held by Chelsio Communications, Inc., an operating company. All recorded transfers are security interests to financial institutions, not transfers of ownership to licensing-only entities.
2. Known asserter in the chain — Not present. None of the listed assignees (Chelsio Communications, Inc., East West Bank, Silicon Valley Bank, Novirian Capital, LLC, Western Alliance Bank, an Arizona Corporation) are known patent asserters or NPEs.
3. Repeat correspondent across the chain — Present.
   • SHEPPARD MULLIN RICHTER & HAMPTON LLP appears on Reel 030232/0330, 032549/0256, and 036325/0747.
   • COOLEY LLP appears on Reel 032549/0259, 047814/0396, 050050/0396, and 061483/0321.
   • O'MELVENY & MYERS LLP appears on Reel 036398/0048 and 038030/0620.
     While multiple correspondent firms recur, they are associated with the financial institutions in security interest transactions, which is typical for such financing arrangements and does not indicate an NPE pattern in this context.
4. Cascading transfers — Not present. Although there are multiple transactions, they are all security interests and releases, not transfers of ownership between chained LLCs. Chelsio Communications, Inc. has retained ownership throughout the recorded history.
5. Pre-litigation transfer — Not present. The previous litigation summary indicates no known litigation cases involving this patent.
6. Bankruptcy fire-sale — Not present. There is no indication that Chelsio Communications, Inc. has filed for bankruptcy, and the transfers are for securing financing.
7. Privateering — Unclear. There is no evidence in the assignment records or provided context to suggest privateering.
8. Defensive aggregator (anti-NPE) — Not present. The patent is held by an operating company, not a defensive aggregator.

Verdict

Insufficient data
There are no recorded transfers of ownership for US 7760733 to any entity other than the original assignee, Chelsio Communications, Inc. The extensive assignment history consists entirely of security agreements and their subsequent releases with various financial institutions, indicating the patent has been used as collateral for corporate financing rather than being transferred for assertion. Therefore, there are no signals to categorize it as an NPE asset.
