Patent 7007259
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
Shell-entity transfer — present. The transfer from Avago Technologies General IP (Singapore) Pte. Ltd. to BELL SEMICONDUCTOR, LLC (Reel 044887/0109, recorded 2017-12-17) suggests a shell entity. Bell Semiconductor, LLC is the current assignee according to Google Patents and is frequently associated with patent assertion.
Known asserter in the chain — present. Bell Semiconductor LLC is a known patent asserter (often referred to as an NPE).
Repeat correspondent across the chain — unclear. The provided data does not consistently list correspondent information, so it's not possible to definitively identify recurring correspondents or link them to known NPE activities.
Cascading transfers — not present. While there are multiple transfers, they are typically separated by more than 24 months or involve security agreements and releases, rather than a rapid succession of assignments through chained LLCs.
Pre-litigation transfer — unclear. The assignment to Bell Semiconductor, LLC occurred in late 2017. A quick search of the Google Patents litigation section shows many cases filed in 2022-2024 by Bell Semiconductor, LLC (e.g., 2:22-cv-10906, 3:22-cv-01178, 1:22-cv-01096), but without precise filing dates for the first suit naming this specific patent, it is hard to say with high confidence if the transfer was within 6 months of litigation. However, the timing is somewhat suggestive, with litigation appearing several years after the transfer.
Bankruptcy fire-sale — not present. LSI Logic Corp. was acquired by Avago Technologies, not involved in a bankruptcy fire sale for this patent.
Privateering — unclear. While Avago/Broadcom transferred the patent to Bell Semiconductor, LLC, there's no explicit evidence within the provided records to confirm a privateering arrangement where Bell Semiconductor is asserting on Broadcom's behalf against competitors.
Defensive aggregator (anti-NPE) — not present. The chain ends with Bell Semiconductor, LLC, which is a known asserter, not a defensive aggregator.
Verdict
NPE — high confidence
The presence of Bell Semiconductor, LLC, a known patent asserter, as the current assignee (Reel 044887/0109, recorded 2017-12-17) is a strong signal. This transfer from an operating company (Avago Technologies) to an entity with a name indicative of a licensing focus, combined with Bell Semiconductor's documented history of patent litigation, strongly points to an NPE pattern.
