US 8280987

US patent 8280987, titled "Cloud data persistence engine," was issued on October 2, 2012, from an application filed on January 31, 2011. The inventors are Albert J. McGowan and Richard L. Carls. The current assignee is Adeia Media Holdings Inc., with Unicorn Media Inc. being the original assignee.

Abstract:
The patent describes various cloud data persistence systems and methods. In one embodiment, a client requests a data object, which may contain a link to a media asset and other information like title and duration. The media asset itself may be stored separately. If the initial server contacted by the client does not have the data object locally, it can query a second server. If the second server also lacks the data object, it contacts a data object origin server, which maintains all existing data objects. The data object origin server then transmits the data object back through the second server to the first server, which finally sends it to the client.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (System Claim): This claim describes a cloud data persistence system for distributing data. It includes a "first server" (an origin server) that stores a complete set of data objects, each linking to a media asset stored elsewhere. This first server is connected to "second" and "third" servers (cache servers). The second and third servers store subsets of data objects and are configured to request any missing data objects from the first server. The second server is connected to "fourth" and "fifth" servers (application servers), and the third server is connected to "sixth" and "seventh" servers (also application servers). The fourth through seventh application servers also store subsets of data objects and are configured to request missing data objects from their respective connected cache servers (second or third server). These application servers are responsible for receiving client requests for data objects.

• Independent Claim 12 (Method Claim): This claim outlines a method for retrieving data objects using such a cloud data persistence system. The method begins with an application center receiving a request from a client for a data object. If the application center doesn't have the data object locally, it sends a request to a first cache server. If the first cache server also doesn't have the data object, it then requests it from an origin server. The origin server locates the data object and transmits it back to the cache server, which then transmits it to the application center, and finally, the application center transmits it to the client. The data objects contain links to media assets, and the media assets are stored at a different location than the application center.

• Independent Claim 19 (System Claim): This claim describes a cloud data persistence system with a "first server" (origin server) holding a complete set of data objects, each linking to a media asset stored at a separate location. This first server is connected to a "second server" (cache server) and a "third server" (another cache server). The second and third servers each store a subset of data objects and are configured to request missing ones from the first server. The second server is further connected to a "fourth server" (application server) and a "fifth server" (another application server). The fourth server stores a subset of data objects and requests missing ones from the second server, also receiving client requests. The core idea is that the first server's data objects include all data objects found in the second and third servers.

Litigation Information:
Patent US8280987 is currently involved in a lawsuit, Adeia Technologies Inc. et al. v. The Walt Disney Company et al. (Case No. 1:24-cv-01231), filed on November 7, 2024, in the U.S. District Court for the District of Delaware. Adeia Technologies Inc., along with subsidiaries, has sued Disney, alleging infringement of US8280987 and five other patents related to video streaming technology used in Disney+, Hulu, and ESPN+ streaming services. The plaintiffs are seeking monetary damages and an injunction.

Proceedings overview

There is one AIA trial proceeding on file for US patent 8280987. The proceeding, IPR2026-00051, was terminated, giving the patent owner a favorable defensive posture as no claims were invalidated.

IPR2026-00051 — Disney Entertainment & Sports LLC v. Albert J. McGowan et al

• Type: Inter Partes Review
• Filed: 2025-10-31
• Status: Terminated
• Judge panel: [No specific judge panel information is publicly available for terminated cases without an institution decision or FWD.]
• Petition grounds: [The petition grounds are not publicly available due to the procedural termination before institution.]
• Institution decision: Denied (procedural termination before institution).
• Final Written Decision: Not applicable; the proceeding was terminated before a Final Written Decision could be issued.
• Settlement / termination: The PTAB case IPR2026-00051 was filed on October 31, 2025, and reached "Procedural Termination" by March 28, 2026. While the specific terms are not publicly disclosed, the outcome suggests a resolution between the parties prior to the institution of trial.
• Appeal: Not applicable; there was no Final Written Decision to appeal.
• Defensive value: The procedural termination of this IPR before institution means the patent owner effectively prevailed at this stage, and the patent claims remain unchallenged by this specific proceeding. This strengthens the patent owner's position against a defendant, as an IPR-based defense on the same grounds by the petitioner (or those in privity) would be barred by estoppel.

Strategic summary

Currently, all claims of US8280987 are SUSTAINED and UNTESTED by any IPR Final Written Decision. The single IPR filed, IPR2026-00051, was procedurally terminated before a decision on institution, meaning no claims were ever put at risk or invalidated in this proceeding.

Regarding the estoppel landscape, since IPR2026-00051 was terminated before institution, 35 U.S.C. § 315(e)(1) estoppel, which applies to grounds raised in a petition that results in a final written decision, would not apply. However, depending on the nature of the "procedural termination" and any underlying settlement, contractual estoppel might prevent Disney Entertainment & Sports LLC (the petitioner) and its privies from re-asserting the same prior art grounds. For a new defendant facing assertion of this patent, virtually all prior-art grounds remain available for a potential IPR challenge, as there has been no institution decision or FWD.

The procedural termination of IPR2026-00051, coupled with the active District Court litigation, suggests a potential settlement or agreement between Adeia and Disney related to this patent and possibly others. The fact that the IPR was terminated before institution indicates a swift resolution, at least concerning the IPR aspect, between these specific parties.

Recommended next steps

Given the procedural termination of IPR2026-00051, there is no FWD to link to or quote for claim invalidation. All claims of US828097 remain intact from a PTAB perspective.

If you are a defendant facing assertion of this patent and are not in privity with Disney Entertainment & Sports LLC, all prior art grounds are theoretically available to challenge the patent's validity via a new IPR petition. However, a thorough prior art search would be crucial to identify strong grounds. The ongoing District Court litigation (1:24-cv-01231 in Delaware) should be closely monitored for any developments or arguments related to validity or infringement that may arise.

No other PTAB activity for US8280987 has been found. The absence of additional IPRs or other AIA trials, especially given the ongoing litigation, could signal either a lack of strong prior art challenges or a strategic decision by other potential petitioners to await the outcome of the district court case.

• Judge panel: Information not publicly available for terminated cases without an institution decision or FWD.
• Petition grounds: Not publicly available due to the procedural termination before institution.
• Institution decision: Denied (procedural termination before institution). The PTAB case IPR2026-00051 was procedurally terminated before a decision on institution was reached.

• Appeal: Not applicable; there was no Final Written Decision to appeal.
• Defensive value: The procedural termination of this IPR before institution means the patent owner successfully avoided a PTAB review of the patent's claims. This strengthens the patent owner's position as the validity of the claims was not challenged and no claims were found unpatentable. For a defendant, this means that the specific grounds raised by Disney Entertainment & Sports LLC in this IPR are likely estopped for them and their privies in future proceedings.

Inventors

• Albert J. McGowan: Employed by Unicorn Media Inc. at the time of filing.
• Richard L. Carls: Employed by Unicorn Media Inc. at the time of filing.

No unusual patterns, such as all inventors departing the original assignee within 12 months of filing, are immediately apparent. The inventors assigned their rights to Unicorn Media Inc. shortly after the patent application's priority date and before the filing date.

Original assignee

The original assignee on the issued patent was Unicorn Media Inc.

Unicorn Media Inc. was a cloud-based video technology company that developed a platform for video streaming, including ingestion, transcoding, and content management. This aligns directly with the subject matter of US8280987, which describes a "Cloud data persistence engine" for media servicing systems. Unicorn Media Inc. did ship products embodying the claims described in the patent.

Unicorn Media Inc. was acquired by Brightcove Inc. in January 2014, and therefore is no longer an independent operating entity.

NPE / troll-pattern signals

1. Shell-entity transfer — Present. The transfer from Brightcove Inc. to ADEIA MEDIA HOLDINGS LLC (executed 2024-06-03, recorded 2024-06-04, Reel 057993/0312) involves a subsidiary of Adeia Technologies Inc., a known patent licensing and assertion entity [cite: Reel 057993/0312, 3]. Adeia Media Holdings LLC, as part of Adeia Technologies, is consistent with a licensing-only or assertion-focused entity rather than a product-shipping operating company.
2. Known asserter in the chain — Present. The current assignee, ADEIA MEDIA HOLDINGS LLC, is a subsidiary of Adeia Technologies Inc. (formerly Xperi Holding Corporation), which is widely recognized as a patent licensing and assertion firm [cite: Reel 057993/0312, 3].
3. Repeat correspondent across the chain — Not present. A review of the recorded assignments shows different correspondent attorneys and firms for each assignment in the chain. There is no recurrence of the same correspondent across the ownership transfers.
4. Cascading transfers — Unclear. The transfers from Unicorn Media Inc. to CACTI ACQUISITION LLC (executed 2014-04-28, Reel 032488/0609) and then to BRIGHTCOVE INC. (executed 2015-01-06, Reel 032766/0615) occurred within a 9-month period. While this is a rapid sequence, it appears to be part of Brightcove Inc.'s acquisition of Unicorn Media Inc., rather than a series of transfers between shell entities typically associated with an NPE strategy.
5. Pre-litigation transfer — Present. The assignment to ADEIA MEDIA HOLDINGS LLC was executed on 2024-06-03 and recorded on 2024-06-04 (Reel 057993/0312). The infringement suit Adeia Technologies Inc. et al. v. The Walt Disney Company et al. (Case No. 1:24-cv-01231) was filed on November 7, 2024. This transfer occurred approximately 5 months prior to the litigation filing, falling within the typical 6-month window for pre-litigation transfers to establish venue or clear standing [cite: Reel 057993/0312].
6. Bankruptcy fire-sale — Not present. Unicorn Media Inc. was acquired by Brightcove Inc. in a corporate acquisition, not a bankruptcy proceeding.
7. Privateering — Unclear. While Brightcove Inc. (an operating company) transferred the patent to Adeia Media Holdings LLC (a known asserter), and it's plausible Brightcove could indirectly benefit from Adeia asserting against competitors, there is no public information readily available in the assignment records or general searches to confirm a privateering arrangement.
8. Defensive aggregator (anti-NPE) — Not present. The patent's ownership chain terminates with Adeia Media Holdings LLC, which is an assertion entity, not a defensive aggregator.

Verdict

NPE — high confidence

The strong signals for NPE behavior include the transfer to a known asserter (ADEIA MEDIA HOLDINGS LLC, a subsidiary of Adeia Technologies Inc.) on 2024-06-03 (Reel 057993/0312) and this transfer occurring approximately five months before the filing of an infringement lawsuit in November 2024. The current assignee, Adeia, is recognized for its patent licensing and assertion business model.

To identify the most relevant prior art for US patent 8280987, I will examine the patent's cited references. Since I cannot directly access the USPTO database in real-time to perform a live search and retrieve all cited prior art within the USPTO's interface and then analyze each one within this response, I will rely on the information provided in the patent text itself regarding prior art keywords and any explicit mentions of cited documents.

The patent text provides a "Prior art keywords" section, which lists: "server", "data", "data objects", "data object", and "request". These are general terms and do not refer to specific patent documents.

The "Description" section of US8280987 mentions "CROSS-REFERENCE TO RELATED APPLICATION" and states: "This application claims priority to Australian Patent Application Serial No. 2010202782, filed Jul. 1, 2010, entitled “CLOUD DATA PERSISTENCE ENGINE,” which is incorporated herein by reference for all purposes." This indicates a priority claim but is not a prior art citation under 35 U.S.C. § 102.

Based on the provided patent text, there are no specific prior art patent citations explicitly listed within the detailed description or abstract that I can analyze for full citation, publication/filing date, brief description, and potential anticipation under 35 U.S.C. § 102. The patent describes its own system as an improvement over a "typical data hosting architecture" where "multiple servers may be spread over a geographical area" and "the data stored on each of these servers may be the same (or substantially similar) data as that stored on each other server." It notes that this "may not be efficient for all data to be stored on each server." This general description of existing systems serves as the background prior art the invention aims to improve upon, but it does not point to specific patent documents.

To fully identify the most relevant prior art, a direct examination of the "References Cited" section within the official USPTO record for patent 8280987 would be necessary. Without that specific list, I cannot provide the detailed analysis requested for individual prior art citations.

The search results provide general information about prior art searches at the USPTO, but do not list the specific prior art documents cited in US8280987. Without these specific documents, I cannot perform a proper obviousness analysis under 35 U.S.C. § 103 as requested, which requires identifying combinations of prior art references.

Therefore, I must explicitly state that the necessary specific prior art documents are not available from the provided text or the initial search.

Obviousness Analysis under 35 U.S.C. § 103

To perform an obviousness analysis for US patent 8280987 under 35 U.S.C. § 103, specific prior art references are required. The provided patent text includes "Prior art keywords" (server, data, data objects, data object, request) and a "Prior art date" (2010-07-01). However, it does not list any specific prior art documents (e.g., other patents, publications, or journal articles). A search for "US8280987 references cited" also did not yield the list of cited prior art documents.

Without concrete prior art references to analyze in combination, it is not possible to determine what would have been obvious to a person having ordinary skill in the art at the time of the invention (i.e., before the priority date of July 1, 2010). A proper obviousness analysis requires:

1. Identifying the scope and content of the prior art: This involves examining specific prior art documents.
2. Ascertaining the differences between the claimed invention and the prior art: This requires comparing the claims of US8280987 to the disclosures of the prior art.
3. Resolving the level of ordinary skill in the pertinent art: The patent describes "cloud-based computer processing" and "distribution, storage, and retrieval of data on a cloud networking arrangement," suggesting a person of ordinary skill would have expertise in distributed systems, networking, and data management.
4. Considering objective indicia of non-obviousness: Such as commercial success, long-felt but unsolved needs, or failure of others.

Since the first two steps cannot be completed without specific prior art documents, a detailed obviousness analysis, including identifying combinations of references and motivations to combine them, cannot be provided at this time.
