Patent 11106744

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.

Inventors

John S. Shriber: Employed by Newsplug Inc. at the time of application filing (2019-01-14).
Roman Zaks: Employed by Newsplug Inc. at the time of application filing (2019-01-14).

Unusual pattern: Both inventors assigned their rights to Slangwho, Inc. on 2019-11-19, approximately 10 months after Newsplug Inc. filed the application US16/247,361 (the parent of US11106744). This departure of all inventors from the original assignee within 12 months of filing often precedes a portfolio transfer.

Original assignee

Newsplug Inc.
Newsplug Inc. developed and offered a news-sharing mobile application called "NewsPlug: Share the News" for iOS and Android, indicating it was an operating company with a product embodying aspects of the patent's claims related to sharing web content and user-generated content for search. Its primary line of business was social news sharing via a mobile app. Its current status appears to be inactive, as its website, Newsplug.com, is "under construction", and the patent was assigned away in February 2023.

NPE / troll-pattern signals

Shell-entity transfer — Present.
- The transfer from Newsplug Inc. (an operating company with a product, but seemingly inactive) to Search And Share Technologies LLC (Reel 059427/0653) is a strong signal. Search And Share Technologies LLC has an NPE-typical name and is actively asserting the patent.
- The intermediary entity Slangwho, Inc., used in the 2019 inventor assignments (Reel 052441/0072, Reel 052441/0073) and immediate re-assignment to Newsplug, Inc. (Reel 052441/0074), also suggests a shell-like intermediary facilitating transfers.
Known asserter in the chain — Present.
- The current assignee, Search And Share Technologies LLC, is actively asserting this patent. This is evidenced by the two federal lawsuits filed in the Texas Western District Court (1:25-cv-01440 and 1:25-cv-01540) in 2025. [cite: https://portal.unifiedpatents.com/litigation/Texas%20Western%20District%20Court/case/1%3A25-cv-01440, https://portal.unifiedpatents.com/litigation/Texas%20Western%20District%20Court/case/1%3A25-cv-01540] Furthermore, Unified Patents, a known anti-NPE organization, has filed an IPR petition (IPR2026-00235) against this patent, listing "Search And Share Technologies LLC" as the patent owner, which confirms its role as an asserter. [cite: https://portal.unifiedpatents.com/[ptab](/ptab)/case/IPR2026-00235]
Repeat correspondent across the chain — Present.
- L. L. LIU of LIU & LIU (18588 VEGAS DR, ROWLAND HEIGHTS, CA 91748) is listed as the correspondent for three assignments executed and recorded on 2019-11-19 (Reel 052441/0072, Reel 052441/0073, Reel 052441/0074), demonstrating consistent legal representation for these consecutive transfers.
Cascading transfers — Present.
- On 2019-11-19, both inventors, John S. Shriber and Roman Zaks, assigned their rights to Slangwho, Inc. (Reel 052441/0073, Reel 052441/0072). On the same day, Slangwho, Inc. assigned its rights to Newsplug, Inc. (Reel 052441/0074). These three rapid, consecutive transfers involving an intermediary LLC are a strong signal.
Pre-litigation transfer — Not present.
- The assignment to Search And Share Technologies LLC occurred on 2023-02-22 (executed date, Reel 059427/0653). The first recorded infringement suits for this specific patent (1:25-cv-01440, 1:25-cv-01540) were filed in 2025. This interval exceeds the 6-month pre-litigation window.
Bankruptcy fire-sale — Unclear.
- There is no public information indicating that Newsplug Inc. underwent bankruptcy proceedings.
Privateering — Unclear.
- There is no publicly available information explicitly detailing a privateering arrangement between Newsplug Inc. and Search And Share Technologies LLC.
Defensive aggregator (anti-NPE) — Not present.
- The patent is not currently held by a known defensive aggregator.

Verdict

NPE — high confidence
This verdict is based on multiple strong signals. Search And Share Technologies LLC is a known asserter, as evidenced by its current involvement in federal litigation in Texas Western District Court and Unified Patents' IPR challenge against it [cite: https://portal.unifiedpatents.com/ptab/case/IPR2026-00235, https://portal.unifiedpatents.com/litigation/Texas%20Western%20District%20Court/case/1%3A25-cv-01440]. The transfer from Newsplug Inc. (an operating company that appears to be inactive) to Search And Share Technologies LLC (Reel 059427/0653) constitutes a shell-entity transfer. Additionally, the rapid, cascading transfers from the inventors through Slangwho, Inc. to Newsplug, Inc. on the same day in 2019 (Reel 052441/0072, Reel 052441/0073, Reel 052441/0074), handled by a single correspondent, strongly indicates a structured patent transaction often associated with NPE activity.
