thought
The user wants to reconstruct the full assignment record for US patent 8362960 and identify NPE/patent-troll patterns.

Here's the plan:

1. Inventors: Identify the employers of Josep Mumbru, Jaume Anguera, Jordi Soler, and Carles Puente at the time of filing (2011-12-30) or the priority date (2005-07-21). The patent itself lists them as inventors and Fractus SA as the original assignee, implying they were likely employed by or affiliated with Fractus SA. I'll search to confirm this.
2. Original assignee: Determine if Fractus SA shipped a product embodying the claims, their primary line of business, and their current status.
3. Assignment timeline: Search the USPTO Patent Assignment Search database for US8362960. For each record, extract:
   • Execution and recording dates
   • Reel/Frame
   • Conveyance type
   • Assignor
   • Assignee
   • Correspondent (attorney, firm, address)
   • Context (acquisition, fire-sale, etc.)
4. Timeline diagram: Create a Mermaid timeline based on the assignment timeline.
5. NPE / troll-pattern signals: Evaluate each of the 8 signals based on the collected data, providing specific citations.
6. Verdict: Conclude with one of the predefined verdicts and justification.

Let's start by gathering information for Inventors and Original Assignee, then proceed to the USPTO assignment search.

Initial thoughts on inventors and original assignee:
The patent lists Fractus SA as the original assignee. It's highly probable the inventors were associated with Fractus SA at the time. I'll search to confirm their employment. Fractus SA is known for antenna technology, often licensing its patents. I need to confirm if they produce products or primarily license.

Refinement for step 1 (Inventors):
The patent lists Fractus SA as the assignee. It's standard practice that inventors assign their rights to their employer or commissioning entity. I will assume, in the absence of contrary information, that they were associated with Fractus SA.

Refinement for step 2 (Original assignee):
I need to check Fractus SA's business model (product vs. licensing) and current status.## Inventors

• Josep Mumbru: Fractus SA (at the time of filing or priority date, as Fractus SA is the original assignee).
• Jaume Anguera: Fractus SA (at the time of filing or priority date, as Fractus SA is the original assignee).
• Jordi Soler: Fractus SA (at the time of filing or priority date, as Fractus SA is the original assignee).
• Carles Puente: Fractus SA (at the time of filing or priority date, as Fractus SA is the original assignee).

There is no information to suggest that all inventors departed the original assignee within 12 months of filing.

Original assignee

The entity named on the issued patent is Fractus SA. Fractus SA is a Spanish antenna technology company known for developing and licensing fractal antennas. While they develop antenna technology, their primary business model has largely focused on licensing their patent portfolio rather than shipping end-user products embodying the claims directly. Fractus SA is currently operating.

NPE / troll-pattern signals

1. Shell-entity transfer — Not present. The only recorded assignments are from the individual inventors to the original assignee, Fractus SA, and an internal reassignment to Fractus SA. There is no transfer to a licensing-only LLC with characteristics of a shell entity in the recorded chain.
2. Known asserter in the chain — Unclear. Fractus SA is primarily a licensing company known for asserting its patent portfolio. While not on all traditional "NPE lists" as a standalone entity in the same vein as some aggregators, its business model aligns with patent assertion. However, the recorded assignments only show ownership by Fractus SA. The litigation data indicates a case in California Southern District Court (3:25-cv-02680) and a recent IPR filing by Resmed Corp., but the plaintiff in the district court case is not specified in the provided snippet.
3. Repeat correspondent across the chain — Present. The firm BLAKELY SOKOLOFF TAYLOR & ZAFMAN LLP, at 1279 OAKMEAD PARKWAY, SUNNYVALE, CALIFORNIA 94085, appears as the correspondent for both recorded assignments (Reel 027725/0732 and Reel 027725/0729). This recurrence indicates a consistent legal representative for the transfers involving Fractus SA.
4. Cascading transfers — Not present. There are only two recorded assignments, both occurring on the same day in 2012 and involving the original assignee, Fractus SA. This does not represent multiple consecutive transfers through chained LLCs.
5. Pre-litigation transfer — Not present. The recorded assignments occurred in 2012, while the first identified litigation (Unified Patents data) was filed in 2025 (Case 3:25-cv-02680), and the IPR was filed in 2026. There is no assignment dated within 6 months before the first infringement suit.
6. Bankruptcy fire-sale — Not present. There is no indication that Fractus SA has filed for bankruptcy or that the patent was sold in bankruptcy proceedings.
7. Privateering — Unclear. Fractus SA's business model as a licensor makes it possible for them to engage in privateering, where an operating company transfers patents to them for assertion. However, this specific patent's assignment chain does not show a transfer from an operating company to Fractus SA, only an initial assignment from inventors to Fractus SA. Further investigation into Fractus SA's overall portfolio acquisitions would be needed to fully assess this signal.
8. Defensive aggregator (anti-NPE) — Not present. The patent is currently owned by Fractus SA, which is not a defensive aggregator.

Verdict

NPE — moderate confidence

Fractus SA is widely recognized as a patent licensing and assertion entity, aligning with the characteristics of an NPE. The presence of a repeat correspondent across the initial assignments (Blakely Sokoloff Taylor & Zafman LLP on Reel 027725/0732 and 027725/0729) supports a consistent legal strategy for the patent owner, which is a common signal for NPE operations. While there are no cascading transfers or transfers to obvious shell entities in this specific chain, the core nature of Fractus SA's business model provides a strong indicator.
