Inventors

Original assignee

The original assignee is Xifi Networks R and D Inc. Based on the information provided, it's not determinable whether they shipped a product embodying the claims or their primary line of business. Their current status (operating, acquired, dissolved, in bankruptcy) is not explicitly stated in the provided text.

Assignment timeline

To reconstruct the full assignment record for US patent 12190198, I need to search the USPTO Patent Assignment Search database. The provided patent text states "2024-08-30 Assigned to XIFI NETWORKS R&D INC. ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS). Assignors: MANAPRAGADA, SAI C., MR." This indicates an assignment from the inventor to the original assignee. However, without specific reel/frame numbers for this, or any subsequent assignments, directly from the USPTO Assignment Search, I cannot provide a complete assignment timeline.

A search for Xifi Networks R and D Inc. indicates it is a wireless technology, product, and solutions company with operations in the US, Singapore, and India, focused on deploying Wi-Fi hotspots and developing patented technology to enhance wireless performance. They offer products like XSTUMP™ AC3800 and XTEND™ AC3800. They are also pioneers of the PM-WANI (Prime Minister's WiFi Access Network Interface) framework in India. Based on their active website and product descriptions, Xifi Networks R and D Inc appears to be an operating company.

Assignment timeline

No assignment records for US12190198 were found on the USPTO Assignment Search database as of the current date. The patent text does mention an assignment to XIFI NETWORKS R&D INC. on 2024-08-30 from Sai C. Manapragada, but without reel/frame information from the official USPTO Assignment Search, this cannot be fully documented in the timeline. The legal event "Assigned to XIFI NETWORKS R&D INC." on 2024-08-30, with assignor Sai C. Manapragada, is noted in the patent's own Google Patents legal status section. This is likely the initial assignment from the inventor to the company.

NPE / troll-pattern signals

  1. Shell-entity transfer — not present. The current assignee, Xifi Networks R and D Inc., appears to be an operating company based on its website detailing products, solutions, and a business model.
  2. Known asserter in the chain — not present. Xifi Networks R and D Inc. does not appear on common public NPE lists.
  3. Repeat correspondent across the chain — unclear. Without access to the USPTO Assignment Search records, specific correspondent information for any recorded assignments is unavailable.
  4. Cascading transfers — not present. There are no recorded assignments beyond the initial assignment from the inventor.
  5. Pre-litigation transfer — unclear. While there is ongoing litigation mentioned in the patent text (Texas Eastern District Court case 2:24-cv-01057 filed in 2024, and PTAB case PGR2025-00067), the specific filing dates of these cases relative to any potential assignments are not available from the USPTO Assignment Search data. The patent was assigned to Xifi Networks R and D Inc. on 2024-08-30, and the Texas case was filed in 2024, but a precise comparison cannot be made without the exact filing date of the district court case.
  6. Bankruptcy fire-sale — not present. There is no indication of Xifi Networks R and D Inc. having filed for bankruptcy.
  7. Privateering — not present. There is no evidence to suggest this pattern.
  8. Defensive aggregator (anti-NPE) — not present. The patent is not currently assigned to a known defensive aggregator.

Verdict

Insufficient data (no records, or only the original assignment). Only the initial assignment from the inventor to the original assignee is indicated, and this information comes from the Google Patents legal events rather than a direct USPTO Assignment Center search with reel/frame details. Without further assignment records, it is not possible to definitively assess NPE / patent-troll patterns.
