• Woojin AHN (Wilus Institute of Standards and Technology Inc.)

All inventors appear to be employed by the original assignee at the time of filing.

Original assignee

The entity named on the issued patent is Wilus Institute of Standards and Technology Inc. Based on the patent's focus on wireless communication methods and terminals, their primary line of business likely involves research, development, and standardization in wireless communication technologies, particularly within the wireless LAN domain (e.g., IEEE 802.11 standards). It is unclear from the provided text whether they directly ship products embodying the claims. Their current status appears to be operating, as they are listed as the current assignee.

Assignment timeline

I'm sorry, but I am unable to access the USPTO Patent Assignment Search to pull the full assignment record for US patent 12167415. The provided search results contain snippets about USPTO Assignment Search in general, but not specific records for this patent.

Therefore, I cannot reconstruct the full assignment record or determine any NPE/patent troll patterns based on assignment data.

NPE / troll-pattern signals

Without access to the USPTO Assignment Center records for US patent 12167415, I cannot definitively determine the presence or absence of specific NPE/troll-pattern signals. However, based on the Google Patents legal events and the general information found:

1. Shell-entity transfer — unclear. There's no assignment data to confirm or deny this.
2. Known asserter in the chain — unclear. While Wilus Institute of Standards and Technology Inc. has initiated litigation against companies like Samsung and HP for other Wi-Fi 6 patents, this specific patent (US12167415) is not mentioned in those complaints in the provided snippets. Wilus is described as an R&D company actively involved in standards development and patent licensing through pools and bilateral agreements, which does not inherently label them as a "known asserter" in the traditional NPE sense, but rather a company that licenses its standard essential patents (SEPs).
3. Repeat correspondent across the chain — unclear. There's no assignment data to confirm or deny this.
4. Cascading transfers — unclear. There's no assignment data to confirm or deny this.
5. Pre-litigation transfer — unclear. While Wilus has engaged in litigation, there's no assignment data for this specific patent to link to litigation filings.
6. Bankruptcy fire-sale — not present. No information suggests Wilus Institute of Standards and Technology Inc. has filed for bankruptcy.
7. Privateering — unclear. There's no assignment data or external reporting on privateering activities specifically for this patent.
8. Defensive aggregator (anti-NPE) — not present. The patent is currently held by Wilus Institute of Standards and Technology Inc., not a defensive aggregator.

Verdict

Insufficient data
I cannot render a definitive verdict on NPE status due to the lack of access to the full assignment record from the USPTO Assignment Center. While Wilus Institute of Standards and Technology Inc. has been identified as an R&D company actively involved in patent licensing and litigation for other patents, the absence of specific assignment data for US patent 12167415 prevents a full analysis of the ownership chain.
