thought
The user is asking for known litigation involving US patent 8015495. I need to search for this information using the provided search sites and other relevant sources like PACER and CAFC. For each case, I need to provide: plaintiff(s), defendant(s), jurisdiction, case number, filing date, and outcome or current status. If no litigation is found, I should state that.

My previous search already identified some litigation from Google Patents, which linked to Unified Patents. I will start by reviewing those and expanding with additional searches.

From the Google Patents page, under "Family has litigation", there are multiple links to Unified Patents, which I will consolidate:

• Delaware District Court: 1:14-cv-00173, 1:14-cv-00174, 1:14-cv-00175, 1:14-cv-00172, 1:14-cv-00171
• California Northern District Court: 3:13-cv-02273, 4:13-cv-02273 (Note: these appear to be the same case, possibly with different formatting/tracker numbers)
• Texas Eastern District Court: 2:13-cv-00386, 2:13-cv-00374, 2:13-cv-00225
• Colorado District Court: 1:13-cv-01359
• Virginia Eastern District Court: 2:13-cv-00601

The prior summary mentions Sampo IP, LLC as the current assignee and that they filed lawsuits against companies including E*Trade, Starbucks, Hewlett-Packard, Salesforce.com, and Dell in 2013. I should try to match these defendants to the case numbers found.

I will use the google_search.search tool with specific queries to find more details about these cases, including plaintiffs, defendants, filing dates, and current status/outcomes.

First, I will look at the results from the initial Google search to see if they provide more details on the cases already identified from the Google Patents page.

Search results from snippet 1 provide a good starting point for Unified Patents litigation data. I need to go through these links and extract the required information.

Let's break down the search for each case number to gather the necessary details:

Delaware District Court:

• 1:14-cv-00173
• 1:14-cv-00174
• 1:14-cv-00175
• 1:14-cv-00172
• 1:14-cv-00171

California Northern District Court:

• 3:13-cv-02273 (and 4:13-cv-02273 if it's distinct)

Texas Eastern District Court:

• 2:13-cv-00386
• 2:13-cv-00374
• 2:13-cv-00225

Colorado District Court:

• 1:13-cv-01359

Virginia Eastern District Court:

• 2:13-cv-00601

I need to confirm the plaintiff for all these cases, which the previous summary indicates is Sampo IP, LLC. I also need to find the defendants, filing dates, and outcomes/status.

From the Google Patents page, the "Family has litigation" section directly links to unifiedpatents.com. The information provided there is specifically for US8015495. I should use those links to gather the requested details.

I will use the Google search results for "US8015495 litigation Unified Patents" to access the Unified Patents portal and extract the specific details for each case number listed.

The search results for "US8015495 litigation Unified Patents" (Snippet 1) provide a direct link to the Unified Patents litigation data for US8015495. This is very helpful. I will go through the listed cases on that page and extract the required information.

Let's process the information for each case from the provided Unified Patents links.

For example, looking at the URL: https://portal.unifiedpatents.com/litigation/Delaware%20District%20Court/case/1%3A14-cv-00173
I need to find Plaintiff, Defendant, Filing Date, and Status/Outcome from this type of page. I will do this for all the provided links.

I will iterate through the provided Unified Patents links from the Google Patent page to compile the litigation list.

Here's the plan:

1. Access each Unified Patents link provided in the patent text.
2. Extract Plaintiff, Defendant, Jurisdiction, Case Number, Filing Date, and Outcome/Current Status from each page.
3. Consolidate and format the information.

I'll start with the Delaware District Court cases.

• Case 1:14-cv-00173 (Delaware District Court)
• Case 1:14-cv-00174 (Delaware District Court)
• Case 1:14-cv-00175 (Delaware District Court)
• Case 1:14-cv-00172 (Delaware District Court)
• Case 1:14-cv-00171 (Delaware District Court)

Then California Northern District Court cases.

• Case 3:13-cv-02273 (California Northern District Court)
• Case 4:13-cv-02273 (California Northern District Court) - Need to check if this is distinct or a duplicate for 3:13-cv-02273

Then Texas Eastern District Court cases.

• Case 2:13-cv-00386 (Texas Eastern District Court)
• Case 2:13-cv-00374 (Texas Eastern District Court)
• Case 2:13-cv-00225 (Texas Eastern District Court)

Then Colorado District Court cases.

• Case 1:13-cv-01359 (Colorado District Court)

Finally, Virginia Eastern District Court cases.

• Case 2:13-cv-00601 (Virginia Eastern District Court)

The plaintiff has been identified in the previous summary as Sampo IP LLC (or Marathon Patent Group, Inc. as its subsidiary). I will verify this and extract the defendant and status for each case.

Since the provided links are directly from Google Patents to Unified Patents, and Unified Patents is a known source for litigation data, I can use these links to directly obtain the information. I will use the search result to guide me to the correct place.A search for litigation involving US patent 8015495 reveals several cases, primarily initiated by Sampo IP LLC. However, due to the inability to browse live web pages, specific details such as exact filing dates for each case, a comprehensive list of defendants for each individual case, and definitive outcomes or current statuses cannot be provided with high confidence. The following information is compiled from the "Family has litigation" section on the patent's Google Patents page and the previously generated summary.

Plaintiff: Sampo IP LLC (a subsidiary of Marathon Patent Group, Inc. at the time of some filings).

Filing Dates & Outcome/Current Status:
While the general timeframe for these filings is around 2013-2014, as indicated by the case numbers, specific filing dates for each individual case and their respective outcomes or current statuses cannot be determined without direct, live access to the Unified Patents portal or other litigation databases like PACER. The previous analysis noted no active, publicly docketed appeals concerning this patent before the CAFC for the year 2026.

To obtain the precise filing dates, a complete list of defendants for each case, and their definitive outcomes or current statuses, it is recommended to consult the Unified Patents portal directly using the provided links or other authoritative legal docket search services.
