NPE / troll-pattern signals

1. Shell-entity transfer — Unclear. While Adeia Guides Inc (formerly Rovi Guides Inc) is heavily involved in patent licensing, it is also associated with active product lines (e.g., TiVo, DTS audio, Xperi automotive solutions) under its broader corporate structure. It operates as an IP monetization entity rather than a pure shell LLC with no other business. The security interest taken by Bank of America also suggests a broader corporate entity.
2. Known asserter in the chain — Present. The current assignee, Adeia Guides Inc (and its predecessor Rovi Guides Inc), is widely recognized in the intellectual property industry for its extensive patent licensing and assertion activities, often being identified by organizations tracking high-frequency plaintiffs.
3. Repeat correspondent across the chain — Unclear. Due to the inability to access live USPTO Assignment Center search results, the names of the correspondents involved in recording these transactions are not available.
4. Cascading transfers — Not present. The ownership chain shows an initial assignment from the inventor, followed by a corporate name change, and a security interest, but no rapid successive transfers between distinct LLCs.
5. Pre-litigation transfer — Not present. As stated in the litigation summary, no litigation involving US11632413 has been found as of April 26, 2026.
6. Bankruptcy fire-sale — Not present. There is no indication that Rovi Guides Inc or Adeia Guides Inc has filed for bankruptcy.
7. Privateering — Unclear. While Adeia engages in aggressive patent licensing, it typically asserts patents directly or through its own subsidiaries, rather than acting as a separate NPE entity hired by another operating company for assertion.
8. Defensive aggregator (anti-NPE) — Not present. The patent is currently held by Adeia Guides Inc, which is not a defensive aggregator.

Verdict

NPE — high confidence

The high confidence verdict is driven primarily by the presence of a known patent asserter, Adeia Guides Inc (formerly Rovi Guides Inc), as the current owner of the patent. This entity has a well-established business model centered on intellectual property licensing and enforcement, fitting the definition of an NPE, even if it has some product divisions. The initial assignment from the inventor to Rovi Guides Inc (event recorded on 2022-07-19) and the subsequent name change to Adeia Guides Inc (event recorded on 2024-10-04) confirm this lineage.

Original assignee

The entity named as the original assignee on the issued patent is Rovi Guides Inc.

Rovi Guides Inc (and its successor, Adeia Guides Inc) is a prominent company known for its intellectual property licensing and media guidance technology. Its business model heavily involves the monetization of a large patent portfolio through licensing agreements with major players in the entertainment and semiconductor industries. While Adeia maintains some product-related operations through its broader corporate structure (e.g., DTS audio and Xperi automotive solutions), a substantial portion of its revenue is generated from IP licensing. Rovi Guides Inc formally changed its corporate name to Adeia Guides Inc, as detailed below. Therefore, the original assignee is operating under a new name and maintains an active business in IP licensing and technology.

NPE / troll-pattern signals

1. Shell-entity transfer — Unclear. While Adeia Guides Inc operates as a pure-play intellectual property licensing company, monetizing patent rights primarily in semiconductors and media entertainment, it is also part of a larger corporate structure that includes other technology brands (e.g., DTS, Xperi automotive solutions). Its focus on IP licensing and enforcement, with high-margin recurring revenue, aligns with how many NPEs operate. However, it is not a simple, single-purpose shell LLC with no other business presence, making a definitive "Present" for "shell-entity" less clear than for pure shell entities.
2. Known asserter in the chain — Present. The current assignee, Adeia Guides Inc (formerly Rovi Guides Inc), is a prominent entity in the intellectual property landscape with a long history of patent assertion and licensing. Adeia and its predecessors (like Rovi and TiVo) are frequently involved in patent litigation against major technology and media companies, as evidenced by numerous legal actions, including against Comcast, Bell Canada, Videotron, and Disney. This strong and consistent pattern of enforcement aligns with the characteristics of a known patent asserter.
3. Repeat correspondent across the chain — Unclear. Due to the inability to access live USPTO Assignment Center search results, the names and firms of the correspondents involved in recording these transactions are not available.
4. Cascading transfers — Not present. The ownership chain includes an initial assignment from the inventor, a corporate name change, and a security interest, but does not show multiple consecutive assignments through chained LLCs within a short period.
5. Pre-litigation transfer — Not present. As stated in the previously generated litigation summary, no litigation naming US11632413 has been found as of April 26, 2026.
6. Bankruptcy fire-sale — Not present. There is no indication from the provided information that Rovi Guides Inc or Adeia Guides Inc has filed for bankruptcy.
7. Privateering — Unclear. Adeia's business model is primarily direct IP licensing and enforcement. While its actions can benefit certain operating companies by enforcing patents they might also hold, it typically operates as the primary asserting entity rather than being a "privateer" acting on behalf of a specific operating company against its competitors.
8. Defensive aggregator (anti-NPE) — Not present. The patent is currently held by Adeia Guides Inc, which is an active patent licensor and enforcer, not a defensive aggregator like RPX or AST.

Verdict

NPE — high confidence

This verdict is based on the strong signal that Adeia Guides Inc (formerly Rovi Guides Inc) is a well-known and active patent assertion entity, whose business model is heavily centered on licensing and enforcing its extensive patent portfolio. Their history includes frequent litigation against major companies to secure licensing revenues. The patent transferred from the inventor to Rovi Guides Inc (recorded 2022-07-19) and later underwent a name change to Adeia Guides Inc (recorded 2024-10-04), maintaining ownership within this established IP monetization framework.
