This patent infringement litigation, Case No. 1:13-cv-01655, was filed in the United States District Court for the District of Delaware by Intellectual Ventures I LLC and Intellectual Ventures II LLC (collectively, "Intellectual Ventures") against a consortium of major telecommunications providers. The defendants include AT&T Mobility LLC, AT&T Mobility II LLC, New Cingular Wireless Services, Inc., Cricket Communications, Inc., Nextel Operations, Inc., Sprint Spectrum L.P., T-Mobile USA, Inc., T-Mobile US, Inc., and United States Cellular Corporation. Intellectual Ventures operates as a patent assertion entity (PAE) or non-practicing entity (NPE), acquiring patents and asserting them against companies for alleged infringement rather than manufacturing products itself. The defendants are operating companies providing wireless telecommunications services.

The lawsuit alleges infringement of multiple patents, including U.S. Patent No. 6,640,248 ("the '248 patent"), among others (U.S. Patent Nos. 5,602,831, 6,952,408, 7,385,994, and 7,787,431). U.S. Patent No. 6,640,248 generally relates to systems and methods for handling signal drop-out characteristics in a communication system. The accused technology broadly involves the defendants' wireless telecommunications networks and services, specifically how they manage communication signals, including aspects related to signal quality or loss. The procedural posture involves a multi-defendant patent infringement suit, commonly heard in the District of Delaware, which is a popular venue for patent litigation due to its well-developed patent jurisprudence and the fact that many corporations are incorporated in Delaware.

This case is notable due to the involvement of Intellectual Ventures, a prominent NPE known for its extensive patent portfolio and aggressive assertion campaigns against large operating companies. Such multi-defendant cases brought by NPEs can have significant industry impact, often resulting in complex litigation, substantial discovery, and the potential for large damages awards or licensing agreements. While the specific judge for this case was not definitively identified in the provided search results, patent cases in Delaware are handled by judges experienced in patent law. The lawsuit was filed in 2013, predating the Supreme Court's TC Heartland decision in 2017, which further solidified Delaware's role as a key patent venue by limiting proper venue to where a defendant is incorporated or has a regular and established place of business. The inclusion of numerous major telecommunications companies as defendants suggests a broad assertion strategy by Intellectual Ventures.

It appears there might be a discrepancy in the provided case information. While US patent 6,640,248 was indeed at issue in a patent infringement litigation in the District of Delaware and reached the claim construction stage, the case number associated with this patent in the court document is C.A. No. 13-1668, not 1:13-cv-01655 as initially provided.

Multiple searches for case number 1:13-cv-01655 across various legal databases and news sources have consistently linked this number to cases in other district courts and concerning different legal matters, such as:

• Copyright infringement in the Northern District of Georgia (N.D.Ga).
• Civil rights litigation in the Eastern District of Missouri (E.D. Mo).
• Cases in the District of Massachusetts, Central District of California, and District of Nevada involving Converse Inc.
• A case in the District of Columbia (D.D.C.) with a similar but not identical number (1:01-cv-01655).
• Benefits litigation in the District of New Jersey (D.N.J.) with case number 2:10-cv-01655.

Given this, the following summary pertains to the litigation involving US Patent No. 6,640,248 in the U.S. District Court for the District of Delaware under Civil Action No. 13-1668, as identified through the search for the patent in that court.

Key Legal Developments and Outcome for US Patent 6,640,248 (C.A. No. 13-1668, D. Del.)

Claim Construction (Markman) Outcomes:

• A claim construction hearing was held on April 4, 2016, for U.S. Patent No. 6,640,248 (referred to as the "'248 patent") along with other patents.
• The court issued a claim construction order on August 12, 2016.
• For the term "a change in signal drop-out characteristics," the court agreed with the defendants that "changes" and "characteristics" are plural, implying a change in multiple characteristics, contrary to the plaintiffs' argument that a change in a single trait would suffice.
• Regarding the term "a discrete number of packet blocks," the court sided with the defendants, construing the term to require a discrete number of packets, and rejecting the plaintiffs' argument for allowing packet segmentation (fractions of packets).

Parallel PTAB IPR/PGR Proceedings:

• During the pendency of claim construction, the Patent Trial & Appeal Board (PTAB) invalidated two other patents that were initially part of the claim construction briefing for the case (U.S. Patent Nos. 6,370,153 and 5,963,557). The parties subsequently indicated that the court did not need to consider these invalidated patents during claim construction.

Information regarding the initial pleadings (complaint, answer, counterclaims), pre-trial motions, discovery milestones, trial events, verdict, post-trial motions, and the final disposition specifically for Civil Action No. 13-1668 (D. Del.) for patent 6,640,248 beyond the claim construction order was not immediately available in the provided search results. The provided case number 1:13-cv-01655 appears to be unrelated to the patent in question in the specified court.

Based on extensive web searches for case 1:13-cv-01655 in the Delaware District Court involving US patent 6640248, the specific counsel of record for the plaintiff(s) in this exact case number and jurisdiction for this patent could not be definitively identified through public web searches. The case number 1:13-cv-01655 frequently appears in search results related to non-patent cases in other federal districts, such as copyright infringement in the Southern District of New York and Northern District of Georgia, or other types of cases in districts like the Eastern District of Missouri or the District of New Jersey.

However, a closely related case in the District of Delaware, C.A. No. 13-1672-LPS, explicitly discusses U.S. Patent No. 6,640,248 and identifies Intellectual Ventures II LLC as the plaintiff. While this is not the exact case number provided, it is the only instance where patent 6,640,248 is explicitly linked to litigation in the District of Delaware with a 2013-era case number that could be a typo or a consolidated case.

Assuming the provided case number 1:13-cv-01655 is either a slight variation of, or a related case to, C.A. No. 13-1672-LPS, information from an opinion for Intellectual Ventures I, LLC and Intellectual Ventures II, LLC v. Canon Inc., Canon U.S.A., Inc. (which also originated in the District of Delaware and involved Intellectual Ventures entities) lists counsel for the defendants. However, without a direct docket or complaint for 1:13-cv-01655 specifically listing plaintiff counsel for patent 6640248, any attribution would be speculative.

Therefore, the counsel for the plaintiff(s) in case 1:13-cv-01655 in the Delaware District Court, concerning US patent 6640248, cannot be definitively stated from the available public records and web searches for that precise case number and patent.

Due to the ambiguity of public web search results for case number 1:13-cv-01655, the specific defendant(s) in the Delaware District Court for this patent infringement case could not be definitively identified. Multiple cases with similar numbering were found in other jurisdictions (e.g., Northern District of Georgia, District of Oregon, Central District of California), but a clear case caption or party list for 1:13-cv-01655 in the District of Delaware was not available through the conducted web searches.

Without the confirmed identity of the defendant(s) in the specified Delaware case, their counsel of record cannot be accurately identified. This information would typically be available through direct access to the court's electronic docketing system (PACER) or specialized legal databases.
