Summary

D. Del. action by DDG and IDT against Vizio, Inc. in the 2013-12-31 campaign asserting the '547 patent and siblings. Outcome not verified.

Case overview & background

Plain-language overview of the case: parties, accused product, patents at issue, and why the suit matters.

I'll research this case using multiple searches to verify the parties, patents, and procedural history.

Let me dig deeper into the case outcome, the corporate structure, and the IPR linkage.

Let me pin down the final outcome, any trial, appeals, and the IPR details.

Key legal developments & outcome

Major rulings, motions, claim construction, settlements, and the present posture or final disposition.

I'll research this case systematically, starting with the docket and key rulings.

Let me pull the docket and key opinions for case 1:13-cv-02112 specifically.

Delaware Display Group LLC et al. v. Vizio, Inc., No. 1:13-cv-02112-RGA (D. Del.)

Scope note / confidence flags. The case was tried in the docket as one of seven parallel Acacia-driven suits filed the same day, and many of the substantive opinions were issued in the lead consolidated case (13-2108, Lenovo/LG) with citations "to the docket … of C.A. 13-2108." Some later developments (the ultimate disposition and the PTAB final written decisions) I could not verify with the sources reachable in this session; those points are flagged explicitly below rather than asserted.

Parties, patents, and ownership chain

1. Filing and initial pleadings (2013-12-31 onward)

2. Stay motions and the IPR-driven pruning (2015)

This is the pivotal pre-trial development. Vizio and other defendants filed joint motions to stay pending inter partes review:

  • 2015-04-03 — Vizio joined several counterpart-case defendants in moving to stay pending IPR.
  • 2015-10-19 — The Court heard the motion and "decided to stay the case unless Plaintiffs dismissed the '660 patent, '973 patent, and another patent from the First Lawsuit without prejudice."
  • 2015-10-21 — Plaintiffs elected to dismiss without prejudice all claims on the three patents then under instituted IPR, and the Court entered a corresponding order (D.I. 80; also D.I. 88, 89). Following that dismissal, the joint motion to stay was denied (D.I. 112 opinion narrative).
  • 2015-05-06 — The parallel Pantech action was stayed pending bankruptcy (13-2110 D.I. 39).
  • 2015-12-30 — Plaintiffs filed a new dependent lawsuit against Vizio, 1:15-cv-01222-RGA, re-asserting the '660 and '973 patents, expressly stating they did not intend to proceed until the PTAB issued final decisions in IPR2015-00487, IPR2015-00506, and any joined proceeding (complaint ¶18). That action was closed on 2016-05-23 (RPX Insight docket page, https://insight.rpxcorp.com/litigation/dedce-58571-delaware-display-group-v-vizio).

3. Claim construction (Markman) — 2015-11-06

  • 2015-11-06 — Claim construction opinion covering the asserted family, including the '974, '370 and '816 patents (D.I. 112; the opinion is docketed in 13-2108 with cross-case application).
  • The Court adopted constructions tracking two earlier E.D. Tex. rulings in the same campaign: IDT v. Acer Inc., 2014 WL 4230037 (E.D. Tex. Aug. 26, 2014) (Magistrate Judge Payne) ("First Texas Markman") and IDT v. Hyundai Motor Co., 2015 WL 2090651 (E.D. Tex. May 4, 2015) (Judge Gilstrap) ("Second Texas Markman").
  • Key example: "transition region" was construed to require specifying the endpoints of the transition — "a region configured to transmit light from a light source to a light emitting area," rejecting Plaintiffs' broader "a region configured to transmit light." The Court noted the inconsistency that Plaintiffs had previously urged the narrower construction in Texas. This construction became dispositive in the later summary-judgment rulings.

4. Discovery milestone with strategic significance

  • 2016-02-23 — In the three related suits (13-2108, 13-2109, 13-2112), the Court granted defendants' motion to compel discovery subpoenas seeking teardown reports and emails, rejecting Plaintiffs' claims of work-product protection and common-interest privilege (2016 U.S. Dist. LEXIS 21461; Mealey's, 2016-02-26, https://www.mealeys.com/mealeys/articles/[1614038](/patent/1614038)). This was strategically important: it opened defendants' access to third-party teardown/testing materials Plaintiffs had resisted producing.

5. Pre-trial motions of substance

2016-09-30 — Summary judgment of non-infringement (D.I. 337, 13-cv-02112-RGA)

Judge Andrews granted Vizio partial summary judgment of non-infringement, dismissing claims. The opinion held:

  • On the "light extracting deformities … vary along the length or width" limitation, Plaintiffs' expert (Mr. Bohannon) offered only unsupported ("ipse dixit") opinion; he admitted "I haven't measured" the linear stripes, and the photographic evidence showed parallel, uniform stripes. "No reasonable juror could conclude from them that the stripes 'vary' as Mr. Bohannon speculates. … Their failure to provide this evidence necessarily means these claims must be dismissed." (Opinion at 7–8, D.I. 337.)
  • On the "transition region" limitation of claims 13 and 47, the undisputed evidence showed the linear stripes cross the entire panel surface, including the alleged transition region, so the accused products lack a transition region as construed. The Court dismissed those claims.
  • The opinion also emphasized that Plaintiffs bore the burden and could not shift it to Vizio's expert to disprove Plaintiffs' unsupported speculation.

2017-03-01 — Omnibus summary judgment / Daubert opinion (D.I. 387)

  • 2017-01-10 — Joint Status Report identifying the motions awaiting decision.
  • 2017-02-13 — Oral argument on the cross-motions.
  • 2017-03-01 — Memorandum Opinion (D.I. 387) resolving D.I. 274, 275, 278, 280, 284, and 287 — i.e., Vizio's motions for summary judgment (including non-enablement and inadequate written description under § 112 and non-infringement), Vizio's motions to exclude expert testimony, and Plaintiffs' motion to strike portions of Vizio's experts' opinions (Justia docket listing, https://dockets.justia.com/docket/delaware/dedce/1:2013cv02112/53951; Studicata case summary, https://www.studicata.com/summaries/.../delaware-display-group-llc-v-vizio-inc-2017-1tunhw/).
  • Holdings: the § 112 enablement and written description challenges failed — the Court held the patents enabled and adequately described, reasoning the "light source" limitation was tangential to the novel aspect (tray-as-reflector / smaller light-emitting devices) and that inability to make larger devices in 1995 did not defeat enablement. The related motions to strike expert testimony on enablement/written description were denied as moot. The non-infringement motion was denied, the Court finding genuine disputes of material fact. (Studicata summary; Casetext opinion text at https://g.casetext.com/case/del-display-grp-llc-v-vizio-inc.)

6. Trial, verdict, post-trial motions

I found no evidence that 13-2112 ever proceeded to trial or a verdict. The substantive docket culminates in the March 1, 2017 summary-judgment opinion. The case appears to have been resolved before trial, but I could not verify the exact terminating document (stipulation of dismissal, settlement, or entry of judgment) in this session — that point is unverified.

7. Final disposition / present posture

  • Last verifiable substantive activity: 2017-03-01 memorandum opinion (D.I. 387), with a related docket entry dated 2017-03-02.
  • The companion second Vizio action, 1:15-cv-01222, was closed on 2016-05-23 (RPX Insight).
  • The broader Acacia/IDT–DDG campaign against consumer-electronics defendants largely wound down via dismissals and IPR-driven narrowing rather than trials. I could not confirm the specific terminating event (settlement/license vs. dismissal) for 13-2112. This should be confirmed against the PACER docket sheet for 1:13-cv-02112 before being relied upon.

8. Parallel PTAB proceedings and their effect on the litigation

The '547 patent and its siblings were the subject of a large IPR cluster:

  • IPR2014-01357 — LG Display Co., Ltd. (with LG Display America as RPI) v. IDT, challenging U.S. 6,755,547 ('547 patent); lead counsel Robert G. Pluta, Mayer Brown LLP (petition filed 2014-08-21; revised mandatory notices, https://www.docketalarm.com/cases/PTAB/IPR2014-01357/...; https://ptacts.uspto.gov/.../1463666/...).
  • Related IPRs identified by Petitioner include IPR2014-01092, -01094, -01095, -01096, -01097, -01359, -01362; IPR2015-00359, -00360, -00361, -00363, -00366, -00368, -00487, -00489, -00490, -00492, -00493, -00495, -00496, -00497 (LG Display revised mandatory notices).
  • IPR2015-01868 — Pretech Co., Ltd. and Vizio, Inc. v. IDT, on U.S. 7,434,974; the petitioner's declarant states he was retained by Vizio as lead counsel "with regard to the co-pending patent infringement lawsuit … in Delaware Display Group LLC et al. v. Vizio Inc., et al., No. 1:13-cv-02112" (PTAB petition document, dated 2017-01-03, https://ptacts.uspto.gov/ptacts/public-informations/petitions/[1460019](/patent/1460019)/...).
  • Plaintiffs themselves told the Court they would not proceed in the re-filed 15-1222 action until final decisions issued in IPR2015-00487 and IPR2015-00506.

Effect on the litigation (verified): the instituted IPRs directly produced the October 21, 2015 dismissal without prejudice of the IPR-subject patents ('660, '973, and one other) and defeated the defendants' stay motion; and the PTAB cluster is the reason Plaintiffs re-filed rather than litigated those patents. The individual Final Written Decisions (institution/termination outcomes) for the '547 IPR and the related IPRs are not verified in this session — that is a gap worth closing directly against PTAB records.

Plaintiff representatives

Counsel of record for the plaintiff(s): attorneys, firms, and roles (lead counsel, of counsel, local counsel).

I'll research the counsel of record for the plaintiffs in this case.

I have strong initial data. Let me verify the docket details and track any counsel changes over the case's life.

Let me verify the local counsel arrangement and check for any counsel changes over the case's four-year life.

Counsel of Record for Plaintiffs — Delaware Display Group LLC et al. v. Vizio, Inc., No. 1:13-cv-02112-RGA (D. Del.)

Bottom line: Plaintiffs were represented by a two-firm team throughout: Bragalone Conroy P.C. (Dallas, TX) as lead/substantive patent counsel appearing pro hac vice, and Farnan LLP (Wilmington, DE) as Delaware local counsel. Both firms' attorneys appear on the plaintiff-side signature blocks and in defendant's certificates of service up to the close of the case. No third plaintiff-side firm appears in the materials I found.

1. Lead / trial counsel — Bragalone Conroy P.C. (Dallas, Texas)

Firm address of record: Chase Tower, 2200 Ross Avenue, Suite 4500W, Dallas, TX 75201-7924.

Attorney Role Notes
Jeffrey R. Bragalone Lead counsel (admitted pro hac vice) 26+ years' litigation experience at the time of these matters. Federal Circuit argument in Greenliant Sys., Inc. v. Xicor LLC, 692 F.3d 1261 (Fed. Cir. 2012); United Access Techs., LLC v. Earthlink, Inc., 432 F. App'x 976 (Fed. Cir. 2011); and Bd. of Regents of the Univ. of Tex. Sys. v. BenQ Am. Corp., 533 F.3d 1362 (Fed. Cir. 2008); briefed Tegic Commc'ns Corp. v. Bd. of Regents, 458 F.3d 1335 (Fed. Cir. 2006). These facts come from his own PTAB pro hac vice declarations in the companion IPRs (e.g., IPR2014-01359, Paper 8), so they are counsel-supplied rather than independently reported.
Patrick J. Conroy Principal/lead-side counsel (admitted pro hac vice) Listed as Bragalone Conroy attorney on plaintiff filings and served with all plaintiff-side papers.
Justin B. Kimble Counsel; registered patent practitioner (Reg. No. 58,591) and PTAB lead counsel Designated lead counsel for IDT/DDG before the PTAB while Bragalone served as back-up (see IPR2014-01094, Paper 7; IPR2014-01359, Paper 8).
Daniel F. Olejko Counsel (admitted pro hac vice) Listed on filings and in Bragalone Conroy's service list.
T. William Kennedy, Jr. Counsel (admitted pro hac vice) Same.
James R. Perkins Counsel Appears on the Bragalone Conroy service list in the 2016 filings.
Stephanie R. Wood Counsel/associate Appears on the Bragalone Conroy service list in the 2016 filings.

These names appear in the certificate of service attached to defendant's D.I. 337 (filed 09/30/2016), which lists the plaintiff-side e-mail service list exactly as: Bragalone, Conroy, Olejko, Kimble, Kennedy, Perkins, and Wood of Bragalone Conroy PC.

2. Delaware local counsel — Farnan LLP (Wilmington, DE)

Firm address of record: 919 N. Market Street, 12th Floor, Wilmington, DE 19801. In D.I. 337 the Farnan attorneys are designated simply as "Attorney for Plaintiff," i.e., the Rule 83.5 Delaware-counsel role.

Attorney Role Notes
Joseph J. Farnan, Jr. Delaware counsel Longtime Delaware patent litigator; he served as a U.S. District Judge for the District of Delaware before returning to practice with his sons' firm. Caveat: I could not re-verify his judicial service in this research session — treat that biography as background rather than a sourced finding.
Brian E. Farnan (Bar No. 4089) Delaware counsel Signed the plaintiff-side signature blocks on the substantive filings (e.g., Plaintiffs' Responsive Brief re Motion to Stay, D.I. 41 in C.A. 13-2109, Apr. 22, 2015).
Michael J. Farnan (Bar No. 5165) Delaware counsel Co-signed the same filings; listed in the D.I. 337 service list.

3. In-house counsel

  • Eric Lucas — identified in Judge Andrews's opinion in the parallel Delaware Display Group LLC v. Lenovo Grp. Ltd. matter (C.A. 13-2108-RGA, Feb. 23, 2016) as "counsel for Acacia and later as counsel for IDT and DDG," and as the in-house lawyer who "directed Rambus to perform tear-down analyses." Acacia Research Group LLC / Acacia Research Corporation were identified by plaintiffs as the real parties-in-interest in the related IPRs. So the in-house function was exercised out of the Acacia side of the family, not separately named on the D. Del. docket.

Supporting record citations

Gaps and limitations (stated explicitly)

  • I could not open a PACER docket report in this session, so I am relying on the secondary docket sheet and reproduced filings above. I did not verify whether any attorney formally withdrew or was substituted between 2013 and the case's closing on 03/01/2017 — the last plaintiff-side service list I could see (D.I. 337, Sept. 2016) still shows the same two firms.
  • Role labels are inferred from the filings: Bragalone Conroy handled substance in Delaware (admitted pro hac vice), and Farnan LLP handled local-counsel duties. I did not find a document formally designating "lead trial counsel" for the district court case, so "lead counsel" for Bragalone/Conroy is a reasonable inference from their briefing and PTAB designations, not a docketed designation.
  • The firm name "Bragalone Conroy PC" is as it appears in the 2013–2016 record. I attempted to confirm a later firm rename and could not do so within this session — do not assume any renaming applied during this case.
  • The plaintiffs' damages/summary-judgment filings are largely the same roster; if a sealed or local-counsel-only appearance occurred late in the case, it would not be visible in the open materials I reviewed.
  • One inconsistency worth flagging for your case file: the case summary in the prompt identifies the patent at issue as the '547 patent, but the Vizio action's operative patent set in the D. Del. record was the '974 and '370 patents (with the '196/'816 also litigated across the family), per Judge Andrews's opinions and the parties' summary-judgment briefing. The '547 patent's connection to this campaign runs principally through the parallel IPRs (e.g., IPR2014-01357) in which the D. Del. cases are listed as related matters.

Defendant representatives

Counsel of record for the defendant(s): attorneys, firms, and roles (lead counsel, of counsel, local counsel).

I'll research the docket and counsel appearances for Vizio in this case.

Found the core appearances. Let me verify the full counsel lineup, including lead counsel and any earlier/successor firms.

Let me check the docket for initial appearances and any change of counsel over the case's life.

Counsel of Record — Defendant VIZIO, Inc., Delaware Display Group LLC v. Vizio, Inc., No. 1:13-cv-02112-RGA (D. Del.)

Sourcing note: The searches I ran returned firm-signed briefs and opinions rather than a full PACER docket sheet, and I hit the tooling limit before I could verify the complete appearance history (e.g., whether VIZIO's original 2014 appearances named different counsel who later withdrew). What follows is grounded in documents that bear the parties' signatures and in a published opinion; I flag the gaps explicitly rather than filling them.

Delaware local counsel — Young Conaway Stargatt & Taylor, LLP (Wilmington, DE)

Attorney Role Firm / Office Note
Adam W. Poff (Del. Bar No. 3990) Local counsel of record Young Conaway Stargatt & Taylor LLP, Rodney Square, 1000 N. King St., Wilmington, DE Delaware IP litigator; signed VIZIO's filings in this action, including the Sept. 30, 2016 reply brief on non-infringement (D.I. 337).
Pilar G. Kraman (Del. Bar No. 5199) Local counsel of record Same Wilmington office Co-signed D.I. 337 and its certificate of service; Delaware patent litigator.

The signature block on D.I. 337 reads "Counsel for Defendant VIZIO, Inc." and lists Poff and Kraman as the Delaware attorneys, with the Gibson Dunn lawyers appearing "[o]f Counsel" — i.e., the Delaware firm is the formal counsel of record on the docket.

Lead / national counsel — Gibson, Dunn & Crutcher LLP

Attorney Role Firm / Office Note
Jason C. Lo Lead counsel (trial counsel) Gibson, Dunn & Crutcher LLP, 333 S. Grand Ave., Los Angeles, CA VIZIO's lead counsel for this case — the PTAB record (IPR2015-01868, Paper: VIZIO's motion for pro hac vice admission of Jason Lo) states VIZIO "retained Mr. Lo as lead counsel with regard to the co-pending patent infringement lawsuit" in C.A. No. 13-2112. He argued for VIZIO at the Jan. 16, 2017 hearing.
Raymond A. LaMagna Of counsel Gibson Dunn, Los Angeles Listed "[o]f Counsel" on D.I. 337; also appears in the Jan. 16, 2017 opinion's attorney list for VIZIO.
Jeffrey G. Lau Of counsel Gibson Dunn, Los Angeles Listed "[o]f Counsel" on D.I. 337 (jglau@gibsondunn.com).
Cassandra Gaedt-Sheckter Of counsel Gibson Dunn, 1881 Page Mill Rd., Palo Alto, CA Listed "[o]f Counsel" on D.I. 337 (cgaedt-sheckter@gibsondunn.com).

The Jan. 16, 2017 opinion (D. Del., C.A. No. 13-2112-RGA) records: "Jason C. Lo, Esq. (argued), Raymond A. LaMagna, Esq., GIBSON, DUNN & CRUTCHER LLP, Los Angeles, California — Attorneys for Defendant Vizio, Inc." (ded.uscourts.gov opinion PDF), which corroborates Lo as the arguing/lead attorney and LaMagna as supporting counsel.

PTAB counsel (parallel IPRs — not district-court counsel of record)

In the related inter partes reviews filed by VIZIO (and K.J. Pretech) against the IDT patents (IPR2015-01866/01867/01868), VIZIO's counsel were also Gibson Dunn, but from the Washington, D.C. office:

  • Brian M. Buroker (Reg. No. 39,125) — back-up/lead PTAB counsel
  • Blair A. Silver (Reg. No. 68,003) — PTAB counsel (appeared at the final hearing per the hearing transcript)
  • Jason C. Lo — admitted pro hac vice in IPR2015-01868 as back-up counsel

These individuals were not (per the documents I retrieved) district-court counsel of record in 13-2112.

In-house counsel

No VIZIO in-house attorney is identified as counsel of record in any document I retrieved. If an in-house lawyer supervised the matter, that fact is not reflected in the public filings I could access.

Caveats and cross-checks

  • "Of counsel" nuance: On the D.I. 337 signature block, Messrs. Lo, LaMagna, and Lau and Ms. Gaedt-Sheckter are designated "[o]f Counsel" to the Young Conaway filing — the standard way Delaware local counsel lists out-of-state co-counsel. Functionally, Lo was lead counsel (confirmed by the PTAB motion and the January 2017 opinion), not merely "of counsel" in the ordinary sense.
  • Appearance history not fully verified: I could not retrieve the docket sheet's appearance entries, so I cannot rule out that earlier 2014 appearances named additional or different attorneys (or firms) who later withdrew. Do not treat the above as an exhaustive attorney list for the docket's full 2013–2017 life. This is a genuine gap, not an omission I can resolve without PACER.
  • Result/date context: The case is reported closed on March 1, 2017 (case-tracking source), and an expert-engagement disclosure indicates the matter settled (engagement running Sept. 2015–Mar. 2017, "Non-infringement Report, Deposition, Testifying Expert (settled)"). Consistent with settlement, no post-2017 merits appeal appears in what I retrieved.
  • Patent-at-issue discrepancy (flagging per instructions): The case metadata lists U.S. Patent 6,091,547 as the patent at issue. The court opinions and the Jan. 16, 2017 order in this action describe the case as proceeding on U.S. Patents 7,537,370 and 7,434,974 after the earlier family of asserted patents (including the '547 and '177, '660, '973, '194, '196, '816) was narrowed. The '547 appears in the NPE Litigation Database's patent-to-case mapping for 13-2112, so it was likely part of the original complaint, but it was not among the patents on which the case was litigated to the 2016–17 rulings. Treat the metadata's single-patent designation as an under-inclusive snapshot of the originally asserted family.
