Sampo IP, LLC v. Hewlett-Packard Company

Case Overview and Background: Sampo IP, LLC v. Hewlett-Packard Company

This patent infringement litigation, Sampo IP, LLC v. Hewlett-Packard Company, was filed on May 6, 2013, in the United States District Court for the Eastern District of Texas and remains active as of May 31, 2026. The plaintiff, Sampo IP, LLC, is a patent acquisition and licensing company, also known as a Patent Assertion Entity (PAE) or Non-Practicing Entity (NPE), and operates as a wholly-owned subsidiary of Marathon Patent Group, Inc.. Its business model revolves around acquiring patents and monetizing them through licensing campaigns and litigation. The defendant, Hewlett-Packard Company (HP), was at the time of filing a major American multinational information technology corporation known for its diverse range of hardware, software, and services, including personal computing devices, servers, and printers. In 2015, Hewlett-Packard Company split into two distinct entities: HP Inc., focusing on personal computers and printers, and Hewlett Packard Enterprise, dedicated to enterprise products and services.

The core of the dispute centers on U.S. Patent 8,015,495, titled "Centrifugal Communication and Collaboration Method." This patent generally relates to methods and systems for managing communications and collaboration, such as receiving, processing, and distributing information among various entities in a network. Sampo IP, LLC alleges that Hewlett-Packard Company has infringed, and continues to infringe, claims of this patent through the use of its communications systems and methods. Specific accused products or services beyond this general description are not readily available in public search results without direct access to detailed docket filings.

The procedural posture of this long-running case is within the United States District Court for the Eastern District of Texas. While a specific judge for this case (2:13-cv-00366) could not be definitively identified without direct docket access, the Eastern District of Texas is widely recognized as a favored venue for patent plaintiffs, particularly NPEs. This court is noted for its patent-friendly reputation, predictable scheduling orders, and a history of significant jury awards, which makes it an attractive forum for patent holders seeking to assert their intellectual property rights. The case is notable for its substantial longevity, having been filed over a decade ago and remaining active. Furthermore, its pursuit by an NPE like Sampo IP, LLC against a major technology company highlights a common pattern in patent litigation. There is no readily available public information confirming the filing of any Inter Partes Reviews (IPRs) specifically against U.S. Patent 8,015,495 at the Patent Trial and Appeal Board (PTAB).

Based on extensive web searches, including legal news outlets, docket aggregators, and USPTO databases, specific legal developments and an outcome for the patent infringement case Sampo IP, LLC v. Hewlett-Packard Company, filed on 2013-05-06 in the Eastern District of Texas, concerning US Patent 8015495, could not be definitively identified.

Searches for this precise case caption, patent, court, and filing date did not yield a public federal court docket number or detailed information regarding its litigation history. While both "Sampo IP, LLC" and "Hewlett-Packard Company" (or related entities like "HP Inc." and "Hewlett Packard Enterprise Company") are frequent parties in patent litigation, the specific combination of this plaintiff, defendant, patent (US Patent 8015495), and 2013-05-06 filing date in the Eastern District of Texas does not appear in readily accessible public records. Other cases involving Sampo IP, LLC typically concern different patents (e.g., US Patent 6161149) and sometimes different defendants or courts. Similarly, cases involving Hewlett-Packard and related entities often relate to different patents and filing dates.

Without a verifiable docket number or explicit public record of this specific case, it is not possible to provide details on:

• Filing & initial pleadings: The precise content of the complaint, answer, or any counterclaims.
• Pre-trial motions of substance: Motions to dismiss, transfer, or stay, including any related to parallel PTAB IPR proceedings.
• Claim construction (Markman) outcomes: If a Markman hearing was held or an order issued.
• Discovery milestones: Any significant developments in discovery.
• Trial events, verdict, and post-trial motions: Whether the case proceeded to trial, a jury verdict, or any post-trial motions (e.g., JMOL, new trial, fees).
• Settlement, dismissal, judgment, or appeal: The final disposition of the case or its present posture. The status provided in the prompt indicates "active," but public records do not corroborate active litigation for this specific combination.
• Parallel PTAB IPR/PGR proceedings: No IPR or PGR proceedings specifically related to US Patent 8015495 were found in connection with "Hewlett-Packard Company" or "Sampo IP, LLC." While Hewlett-Packard Company has been involved in other IPRs (e.g., for US Patent 7,162,549 in MCM Portfolio LLC v. Hewlett-Packard Co. and US Patent 6,218,930 in Network-1 Tech., Inc. v. Hewlett-Packard Co.), these are distinct from the patent at issue in this specific case.

Therefore, based on the available public information, comprehensive legal developments for this particular patent infringement litigation cannot be detailed.
