Cedar Lane Technologies Inc. v. Charter Communications, Inc.

I'll research this case thoroughly before writing the overview.

Good foundation. Now let me dig into the patents, the Delaware transfer, and any IPR challenges.

Now let me verify the Delaware outcome, the '194's technical scope and claim, and any IPR activity on the '194 specifically.

Case Overview — Cedar Lane Techs. Inc. v. Charter Commc'ns, Inc., No. 2:19-cv-00368 (E.D. Tex.)

The parties. Cedar Lane Technologies Inc. is not an operating company. It is a Canadian (British Columbia) patent-assertion entity incorporated on April 29, 2019, with attorney Greg Benoit as director and a listed address corresponding to IP licensing firm Pigott & Co.; it has disclosed in court that it has no parent and no publicly held owner of 10% or more. It is one of the most prolific NPEs of the 2019–2023 period — DISH's SEC disclosures describe it as "a non-practicing entity that has filed more than 75 patent infringement lawsuits," and by late 2022 commentators counted hundreds of filings, concentrated in W.D. Tex. before Judge Albright (DISH DBS 10-Q/10-K disclosure; Mondaq, "NPE Showcase – Cedar Lane Technologies," Oct. 6, 2022). Cedar Lane's sole counsel of record here was Isaac Phillip Rabicoff of Rabicoff Law (Dkt. 3). Charter Communications, Inc. is a Fortune 500 cable/broadband operator (Spectrum brand) and a Delaware corporation — a fact that drove the case's procedural fate. The patents themselves are second-generation assets: they were developed by four unrelated startups (Synetix Technologies, Relatable LLC, PhatNoise Inc., and MONKEYmedia Inc.), sold into Intellectual Ventures, packaged into Delaware NPE AVInnov LLC in December 2018, and then assigned in bulk to Cedar Lane by assignment dated October 7, 2019 — roughly one month before suit (RPX, Nov. 9, 2019).

The accused technology and the patents. The accused instrumentalities are Charter's cable set-top boxes and the video/audio streaming and on-screen-navigation features delivered through them; RPX summarizes the campaign as targeting "the defendants' respective cable boxes," and the complaint was filed with ten exhibits (A–J) consisting of claim charts (Dkt. 1). One important caveat on the record: this case's metadata lists only U.S. Patent 6,502,194, but the complaint actually asserted four patents, and I write to both — the '194 appears to be the lead/representative patent in the database record, while the docket and Cedar Lane's subsequent Delaware pleadings confirm all four were pleaded. A one-line sketch of each: 6,502,194 — "System for playback of network audio material on demand" (filed Apr. 16, 1999; issued Dec. 31, 2002; inventors Berman, Radford, Kennedy, Matsumoto; originally Synetix): a set-top-like playback appliance that streams audio from a network server to a conventional home stereo, using a minimal non-user-accessible OS and buffering only portions of a track so the complete composition is never resident in memory, with copy-authorization flags gating digital output (claim text). 6,526,411 — "System and method for creating dynamic playlists" (Relatable LLC; sole inventor Sean Ward; ~1999 priority). 6,721,489 — "Play list manager" (PhatNoise, Inc., the pre-Harman media-manager company; issued Apr. 2004). 7,173,177 — "User interface for simultaneous management of owned and unowned inventory" (MONKEYmedia, Inc.; issued Feb. 2007), i.e., a UI that shows whether playlist items are already owned. Two observations worth flagging: the '194's face-date math (20 years from an April 16, 1999 filing) puts nominal expiry around April 2019 — before this November 2019 complaint — and RPX lists the patent as "expired due to term," which, absent unverified patent term adjustment, would confine recovery to pre-expiration conduct within the § 286 six-year lookback. I have not verified whether the '194 received PTA, so treat that as a defensive theory rather than an established fact. I also could not review the Exhibit A–J charts themselves, so the specific Charter models accused are not verified here.

Procedural posture and why it matters. Cedar Lane filed on November 9, 2019 in E.D. Tex., Marshall Division, assigned to Chief Judge Rodney Gilstrap with referral to Magistrate Judge Roy S. Payne; the complaint sought willful infringement and a jury (Dkts. 1–5). The Texas stay was short: on February 28, 2020 the

I'll research this case systematically, starting with the docket and transfer proceedings.

Now let me dig into the Delaware case docket and any IPRs on the other asserted patents.

Let me find the Delaware docket and the ultimate disposition.

Case Snapshot

1. Chronology

*2019-02-22 — Pre-history: AVInnov LLC v. Charter Communications, Inc., 1:19-cv-00373 (D. Del.).* The same four patents were first asserted against Charter in Delaware by AVInnov LLC, the prior NPE owner. AVInnov voluntarily dismissed before the answer deadline, in early August 2019. (RPX, In a Matter of Months, Former IV Portfolio Bounces Off One NPE to Land in New Cedar Lane Complaints, 2019-11-09.)

2019-10-03 — Parallel PTAB petition. Unified Patents, LLC (a defensive aggregator, not a party to the litigation) filed IPR2020-00006 against U.S. Patent 7,173,177. This petition predates the complaint by five weeks — i.e., the invalidity challenge was already in motion when Cedar Lane sued.

2019-10-07 — Assignment. AVInnov assigned its portfolio to Cedar Lane Technologies Inc., a British Columbia entity formed 2019-04-29 (director: attorney Greg Benoit). Cedar Lane acquired the patents roughly one month before filing.

2019-11-09 — Complaint (Dkt. 1). Cedar Lane sued Charter in E.D. Tex. on all four patents, with ten exhibits (A–J, presumably claim charts and prosecution documents), jury demand, and a willfulness theory. Counsel for plaintiff: Isaac Phillip Rabicoff (Rabicoff Law LLC), who signed the complaint and the Rule 7.1 disclosure (Dkts. 3–4). Cedar Lane simultaneously sued Frontier (2:19-cv-00369, E.D. Tex., '194/'411/'489) and Starz Entertainment (1:19-cv-03189, D. Colo., '411/'489/'529) on the same day.

2019-11-12 / 2019-11-27 — Assignment and referral. Case assigned to Judge Gilstrap; referred to Mag. J. Payne (2019-11-27).

2019-12 to 2020-01 — Service problems. The first summons (2019-11-12, c/o The Corporation Trust Company) evidently did not take; a second summons issued 2020-01-07 c/o Corporation Service Company. This ~60-day gap is the only real "discovery milestone" of the Texas phase, and it is a service issue, not a merits development.

2020-02-28 — Joint stipulated motion to transfer and stay (Dkt. 7). Charter, through counsel Thomas Duston, moved — jointly with Cedar Lane — to transfer the case to the District of Delaware and to stay all deadlines. Note the strategic posture: this was a stipulated § 1404 motion, not a contested TC Heartland or § 1406 fight. Cedar Lane did not resist returning to the forum it had abandoned via AVInnov. (Unified Patents litigation portal, 2:19-cv-00368 docket.)

2020-03-08 (entered 2020-03-09) — Transfer order. Mag. J. Payne granted Dkt. 7, transferring the case and staying deadlines.

2020-03-18 — IPR2020-00006 instituted against the '177 patent (panel: Kaiser, Beamer, Howard). Ten days after the transfer order. (Patexia, IPR2020-00006 docket summary.)

2020-04-03 — Case opened in D. Del. as 1:20-cv-00473; E.D. Tex. case closed the same day (RPX Insight; docket acknowledgment of receipt).

2021-02-12 — PTAB final written decision in IPR2020-00006. The Board (opinion by Chief/APJ Christopher M. Kaiser) held the asserted independent claim of the '177 patent unpatentable, on Unified Patents' challenge to claims 1–26. (Unified Patents, Cedar Lane patent held unpatentable, 2021-02-12.)

Post-transfer disposition. The D. Del. case ended in dismissal of Cedar Lane's claims rather than judgment. The Korea IP Protection Center's litigation database (drawing on U.S. docket data) records the outcome of 1:20-cv-00473 as 소취하 ("voluntary dismissal/withdrawal"). I was not able to retrieve the D. Del. docket itself to confirm the docket number of the dismissal, its date, or whether it was with or without prejudice — see § 6 below.

2. Stage-by-Stage Analysis

Pleadings. There was never a merits answer or counterclaim in E.D. Tex. Charter's response to the complaint took the form of a joint transfer motion filed 2020-02-28, roughly 3½ months after filing and after the service reset. That is itself telling: rather than plead invalidity/non-infringement in Marshall, Charter and Cedar Lane jointly relocated to Delaware — the venue where Charter is at home (Delaware corporation) and where the predecessor AVInnov case had been filed. In D. Del., an answer with declaratory-judgment counterclaims of invalidity and non-infringement would have been the ordinary course, but I cannot confirm the filing date or content from available sources.

Pre-trial motions of substance. The only substantive motion in the case file that I can verify is the stipulated transfer/stay motion (Dkt. 7), granted 2020-03-08. There was no motion to dismiss, no contested transfer motion, no motion to stay pending IPR in the district court, and no summary judgment motion — the case simply did not live long enough. Cedar Lane's practice in this campaign was high-volume, short-duration filing followed by early exit, so the absence of contested motion practice is consistent with the portfolio-wide pattern.

Claim construction. None. No Markman hearing, no joint claim construction statement, no Phillips briefing. The case never reached a scheduling order in Delaware that I can verify.

Discovery. None of record. No document production, no depositions, no damages/contentions disclosures surfaced. The only pre-transfer "milestone" with any strategic weight is the service delay (summons reissued 2020-01-07), which effectively bought Charter time and preceded the joint transfer motion by seven weeks.

Trial / verdict / post-trial motions. None. No JMOL, no new-trial motion, no fee motion under § 285.

Final disposition / appeal. Dismissal by Cedar Lane (per the Korean IP-center database entry), i.e., an early voluntary exit rather than a judgment on the '194 or any other patent. No appeal to the Federal Circuit appears in any of the sources reviewed.

3. Parallel PTAB Proceedings and Their Effect

IPR2020-00006 — U.S. Patent 7,173,177 (Unified Patents, LLC v. Cedar Lane Technologies Inc.). Petition 2019-10-03; instituted 2020-03-18; FWD 2021-02-12 holding the asserted independent claim unpatentable. Unified was represented by in-house counsel Michelle Callaghan and Roshan Mansinghani, with Husch Blackwell as outside counsel.

Effects on this litigation:

• The '177 was one of the four patents asserted against Charter, and it was the patent most widely asserted across Cedar Lane's campaign — RPX and Unified both note assertions against Spectrum/Charter, T-Mobile, Disney, Dish, CBS/ViacomCBS, and others. A February 2021 adverse FWD therefore stripped a claim from the Charter case (and from a dozen-plus others) without any district court ruling.
• Timing matters procedurally: institution (2020-03-18) came ten days after the Texas transfer order, so the case arrived in Delaware already carrying an instituted IPR against one of its four patents. That materially reduced Cedar Lane's leverage in Delaware and is the most plausible driver of the eventual dismissal, though no source states the dismissal was IPR-driven.
• I found no IPR, PGR, or ex parte reexamination directed at the '194, '411, or '489 patents in the sources reviewed. The '194 — the patent the case metadata flags — appears never to have been the subject of a PTAB challenge in this period, so the invalidity pressure on this case was concentrated in a single patent.
• No appeal of the '177 FWD to the Federal Circuit appears in the sources reviewed; the 63-day appeal window would have run in mid-April 2021. I cannot confirm affirmatively that no appeal was taken.

Related PTAB activity in the campaign. Cedar Lane's parallel cases attracted additional PTAB attention — e.g., DISH Network's ex parte reexamination requests on other Cedar Lane patents (granted November–December 2020, per DISH's SEC disclosures) — but those concerned different patents ('784, '799, '318, '970) and different defendants, not the Charter case.

4. Why This Case Matters Despite Never Being Adjudicated

1. **It is a pure example of NPE forum-shopping

I'll research press coverage of this case across multiple angles.

Let me dig into the '194 patent specifically and the later Delaware case.

Now let me look for legal-trade coverage and the outcome of the Delaware refiling.

Press coverage of Cedar Lane Technologies v. Charter Communications (E.D. Tex. 2:19-cv-00368)

Bottom line: this case generated almost no mainstream or national legal-press coverage. I searched the caption, party names, the asserted patent numbers (including the '194 patent in the metadata and the full four-patent family), the Delaware refiling number, and post-transfer outcomes. I found no Reuters, Bloomberg Law, Law360, Ars Technica, The Verge, IPWatchdog, Patently-O, EFF, or JD Supra article about this suit. What exists is one substantive trade write-up at filing, a PTAB-focused blog post from a defense-side organization, and docket-intelligence records. There is no reported verdict, damages figure, or settlement term for this case in any source I located.

The one detailed account is RPX's filing-day report. RPX reported on 2019-11-09 that Cedar Lane — a Canadian NPE formed in British Columbia on April 29, 2019, with attorney Greg Benoit as director and a listed address corresponding to IP licensing firm Pigott & Co. — re-asserted four former Intellectual Ventures patents against Charter in the Eastern District of Texas, accusing Charter's cable boxes. RPX framed the suit's significance as sequencing rather than technology: AVInnov LLC had sued Charter on the same four patents in Delaware in February 2019 and voluntarily dismissed in early August, then assigned its entire portfolio to Cedar Lane by assignment dated October 7, 2019, and Cedar Lane refiled roughly a month later. RPX identified the patents as 6,502,194, 6,526,411, 6,721,489, and 7,173,177, traced the '194 patent to Synetix Technologies (issued December 2002, estimated April 1999 priority, with inventor/CEO Russell T. Berman signing the July 2006 transfer to an IV affiliate), and noted Cedar Lane filed parallel suits that same day against Frontier in E.D. Tex. and Starz in D. Colo. Notably, RPX's account goes beyond what a bare complaint summary would show — it is the source for the corporate-formation details, the chain-of-title history, and the observation that Cedar Lane had already launched three assertion campaigns from the former IV portfolio. No outlet reported a damages demand; the complaint sought willful-infringement remedies, and RPX records the cause of action as willful infringement with no disclosed figure.

The only other substantive item is a PTAB development reported by a defense-side organization — and it concerns a different patent in the same campaign. Unified Patents announced that on March 18, 2020 the PTAB instituted trial on all challenged claims of U.S. Patent 7,173,177 in Unified's IPR2020-00006, describing the '177 patent as "directed to indicating on a user interface whether items in a playlist are owned or unowned" and as having been "asserted against Spectrum (Charter Communications)." That post identifies Unified's counsel (in-house Michelle Callaghan and Roshan Mansinghani, with Husch Blackwell) — an executive/party-adjacent statement rather than neutral reporting, and it does not address the '194 patent that the case metadata lists as the patent at issue. RPX had earlier flagged the same petition as filed in early October 2019 with no institution decision yet. I found no press reporting of any IPR or validity challenge specific to the '194 patent.

Where the record and any "reporting" diverge, and how the case ended. RPX and the complaint describe four patents in suit, whereas the case metadata here lists only the '194 patent — worth flagging as a scope discrepancy rather than a press conflict. The procedural end is documented in docket-intelligence sources, not journalism: Unified Patents' litigation portal records a stipulated joint motion to transfer to D. Del. and stay deadlines filed 2020-02-28 by Charter, granted by Magistrate Judge Roy S. Payne on 2020-03-08, with the case opened in Delaware as 1:20-cv-00473 on 2020-04-03; RPX Insight lists the E.D. Tex. case as closed 2020-04-03 after 147 days. A Korean government IP-dispute database maintained by KOTRA/Korea IP Protection Agency records the Delaware refiling's first-instance result as a withdrawal (소취하) — i.e., voluntary dismissal — but I could not corroborate that against PACER or any news account, so treat the termination mechanism as unconfirmed. For portfolio context only, Bloomberg Law reported on 2026-06-04 that Cedar Lane filed 52 cases in 2025 but only 10 so far in 2026, citing it as Exhibit A for high-volume filers pulling back — but that article does not discuss the Charter matter. Any claim that this case produced a settlement payment, license, or injunction is unsupported by press reporting I could find.

I'll research the docket and counsel records for this case.

I'll research defense counsel in this case, starting with docket-oriented searches.

Key lead: the joint transfer motion was filed by Thomas Duston (Marshall, Gerstein & Borun, Chicago). Let me nail down the full appearance list in both forums.

Defense Counsel of Record — Cedar Lane Techs. v. Charter Commc'ns, No. 2:19-cv-00368 (E.D. Tex.)

Bottom line

Defense-side activity in the E.D. Tex. case was minimal — the case was resolved by a stipulated transfer (Dkt. 7 joint motion, granted 3/8/2020 by Mag. J. Roy S. Payne, case opened in D. Del. as 1:20-cv-00473 on 4/3/2020). Consequently, the docket reflects a very thin defense appearance record. Only one Charter attorney is affirmatively documented in this case:

Evidentiary basis and docket posture

• Dkt. 7 (2/28/2020) is captioned as filed "by Charter Communications, Inc." with the ECF filer signature block attributed to Duston — the only appearance of defense counsel captured in the E.D. Tex. docket as reported by the free aggregators (Justia docket, last retrieved 1/7/2020; Unified Patents litigation portal).
• The docket's pre-transfer entries (Dkts. 1–6) are all plaintiff-side (complaint, AO 120, corporate disclosure, Rabicoff appearance, two summonses) — consistent with the earlier section on plaintiff's representatives. No answer, Rule 12 motion, or invalidity contentions were ever filed in E.D. Tex., because the joint motion also sought to stay all deadlines.
• The Justia snapshot was captured 1/7/2020 — before the transfer motion was filed — so it does not itself show any defense appearance; the Dkt. 7 filing is sourced from the Unified Patents docket mirror and from Marshall Gerstein's own PTAB filings in related matters.

What I could not verify (flagging rather than guessing)

• No local E.D. Tex. counsel is documented. Local Rule AT-2 would ordinarily require local counsel for a Texas case, and a pro hac vice motion would normally be on the docket — but no free source I could access shows a local-counsel appearance or PHV motion in 2:19-cv-00368. Because defense-side activity consisted of a single stipulated motion filed roughly three months after service, it is plausible an appearance was made and simply not surfaced in the aggregator dockets, but I have no filing to cite, so I am not naming anyone.
• Delaware counsel in 1:20-cv-00473 is unverified. The transferred case was terminated by voluntary dismissal (reported outcome "소취하"/voluntary dismissal for 1:20-cv-00473 per the Korean IP-protection agency's WIPO-style case digest, KOTRA dream database). Given Delaware's local-counsel practice, a Delaware firm almost certainly appeared there, but I could not pull the 1:20-cv-00473 docket sheet and will not infer a firm name.
• No in-house Charter attorney appears on either docket. Charter appears to have litigated this matter entirely through outside counsel — a common pattern for it.
• Caution on cross-contamination: several search hits (e.g., IPR2025-00473 petition papers) show Charter's counsel in other cases — Raymond R. Ricordati III as lead IPR counsel for Charter, with Duston as back-up, both at Marshall Gerstein. Those are IPR2025-00473 (Iarnach) and 2:24-cv-00230, not this case. I include them only as evidence of the firm's ongoing Charter relationship, not as appearances here.

Context on counsel's relevant patent experience

Duston is a recurring defense counsel for Charter in patent suits, which supports his identification as lead here: he entered appearances for Charter in SynchView Techs., LLC v. Charter Commc'ns (E.D. Tex., No. 2:18-cv-00437, appearance 10/24/2018), Preferential Networks IP, LLC v. Charter/Spectrum (E.D. Tex., No. 2:17-cv-00626), Oceana Innovations LLC v. Charter (W.D. Tex., No. 6:20-cv-00432, appearance 6/18/2020), and Monarch Networking Sols. LLC v. Charter (E.D. Tex., No. 2:19-cv-00300), where his Charter appearance terminated 7/30/2020 per the docket excerpt reproduced in a PTAB petition exhibit.

Verification recommendation

Because the free dockets for 2:19-cv-00368 stop at the transfer and are partly pre-dated, the definitive counsel list requires a PACER pull of the full E.D. Tex. docket sheet (check for any "Notice of Attorney Appearance" / PHV motion between 2/2020 and 4/2020) and of D. Del. 1:20-cv-00473 for Delaware local counsel and the dismissal papers. I'd rather flag those two gaps than populate them from inference.
