NPE / troll-pattern signals
- Shell-entity transfer — not present. The transfers are between FedEx entities, which are operating companies.
- Known asserter in the chain — not present. Federal Express Corp is an operating company, not a known NPE.
- Repeat correspondent across the chain — present. Donald L. Baker of Federal Express Corporation, Legal Dept. Intellectual Property, appears as the correspondent for all three recorded assignments (Reel 032231/0724, Reel 064972/0642, and Reel 064972/0644).
- Cascading transfers — not present. The transfers are separated by a significant time period (10 years) and are internal corporate actions.
- Pre-litigation transfer — unclear. While litigation is noted, the exact timing of the first infringement suit relative to the 2014 assignment from inventors is not explicitly detailed in the provided information. However, the 2024 merger events are well after the initial litigation noted in the patent summary (Delaware District Court case filed in 2021).
- Bankruptcy fire-sale — not present. No indication of bankruptcy proceedings for FedEx Corporate Services Inc or Federal Express Corporation.
- Privateering — not present. The patent remains within the FedEx corporate structure.
- Defensive aggregator (anti-NPE) — not present. The current assignee is an operating company, not a defensive aggregator.
Verdict
Operating-company assertion. The patent has remained within the FedEx corporate structure, first with FedEx Corporate Services Inc and then through a merger with Federal Express Corporation (Reel 064972/0642, Reel 064972/0644). Federal Express Corp is a large operating company that develops and utilizes logistics systems, which aligns with the subject matter of the patent. The presence of a repeat correspondent (Donald L. Baker, Federal Express Corporation) across all assignments further supports this being an internal corporate chain.
