Cedar Lane Technologies Inc. v. Neosapience, Inc.

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

Interesting — I'm seeing a conflict between the metadata and third-party databases on the patent number, plus a docket showing the case has since closed. Let me dig deeper.

Key finding: the docket shows the case was dismissed with prejudice in January 2026, and the campaign appears broader than the metadata suggests. Let me verify the patent and the campaign details.

Case Overview & Background

Parties. Plaintiff Cedar Lane Technologies Inc. is a Canadian patent-holding entity (commonly reported as Toronto-based) that the Stanford NPE Litigation Database classifies as a non-practicing entity whose sole asserter category is "acquired patents." It does not make or sell products; it monetizes a purchased portfolio, and IPWatchdog's filing roundups have tagged its imaging-array suits as an "Intellectual Ventures" / "IV selloff" portfolio. Its litigation is run through Rabicoff Law LLC (Isaac Phillip Rabicoff), a high-volume, complaint-driven practice. Cedar Lane has filed well over a hundred infringement suits since ~2019, largely in W.D. Tex., D. Del., E.D. Va., and E.D. Tex. Defendant Neosapience, Inc. is a Seoul-based generative-AI voice company founded in November 2017 by former Qualcomm/KAIST engineers (CEO Taesu Kim). Its flagship product, Typecast, converts scripts into emotionally expressive synthetic speech using a library of 720+ voice IPs; the company reports ~3.2 million registered users across 226 countries, 2025 revenue of roughly KRW 10.6 billion (approximately 66% three-year CAGR), a U.S. subsidiary established in 2023, an announced USD 11.5M pre-IPO round on December 11, 2025, and a KOSDAQ listing (priced at KRW 10,000/share) targeted for September 2026. In short: a serial Canadian NPE versus a Korean AI-voice startup on the eve of its IPO — not an operating-company-versus-operating-company dispute.

Asserted patent(s) — with an important sourcing caveat. Our case metadata lists U.S. Patent No. 6,972,790. I was unable to verify that from the docket-level record, and the case-specific records I could retrieve point instead to U.S. Patent No. 8,438,485. Both are Cedar Lane assets, so here is a one-line sketch of each, with the discrepancy flagged rather than resolved:

• 6,972,790 — "Host interface for imaging arrays" (inventor Mark Suska; issued Dec. 6, 2005; earliest priority Jan. 21, 2000): a FIFO/addressable-memory interface that buffers image-sensor data and clock signals and generates interrupts or bus requests to a host processor — the workhorse patent of Cedar Lane's 2019–2023 camera/surveillance campaign. Third-party data indicates it went inactive/expired around Aug. 1, 2023, which would confine any 2025 assertion to pre-expiration damages inside the § 286 lookback window. It has no apparent technical relationship to a text-to-speech company.
• 8,438,485 — "System, method, and apparatus for generating, customizing, distributing, and presenting an interactive audio publication" (issued May 7, 2013; priority Mar. 17, 2009; estimated expiry Dec. 28, 2030; originally prosecuted by Weaver IP for UNEWS, LLC): a system that ingests text- or speech-based content items, converts them into metadata-tagged audio segments, assembles them into a navigable "audio publication" according to a subscriber-defined template with assignment rules, and delivers it for interactive, non-linear playback via voice commands or buttons — i.e., a rule-based, template-driven personalized audio/TTS publishing engine. Independent claims 1 and 26 are the operative framing; the complaint's own infringement narrative (as captured in third-party complaint analyses) tracks the '485 and identifies accused functionality only generically through an "Exhibit 2" claim chart rather than by naming products in the body.

Given that Cedar Lane's parallel 2025–2026 filings against Eleven Labs (S.D.N.Y. 1:25-cv-07842, filed 9/22/2025), Canva (W.D. Tex. 7:25-cv-00271, filed 10/6/2025), Descript (D. Del. 1:25-cv-01567, filed 12/30/2025), and Speechify (D. Del. 1:26-cv-00031, filed 1/12/2026) all report 8,438,485 as the patent-in-suit, the '485 is almost certainly the patent actually asserted here, and the '790 field in our metadata looks like a portfolio-level or inherited data error. This should be reconciled against the Dkt. 1 PDF before the record is relied on.

Procedural posture — the case is already over. Filed August 20, 2025 in the Marshall Division of the E.D. Tex. before District Judge Rodney Gilstrap, with Magistrate Judge Roy S. Payne referred; jury demand by plaintiff. Service was effected October 15, 2025; Neosapience (through Charles S. Baker of Troutman Pepper Locke LLP) obtained an unopposed extension to December 22, 2025 (Dkts. 6–7), and Magistrate Judge Payne set a scheduling/case-management conference for January 22, 2026 (Dkt. 8). There was never an answer, a Rule 12 motion, a claim-construction proceeding, or any disclosed IPR. On December 26, 2025 Cedar Lane filed a Notice of Voluntary Dismissal (Dkt. 10), and on January 13, 2026 Judge Gilstrap entered an order dismissing all claims with prejudice under Rule 41(a)(1)(A)(i), each party to bear its own costs and fees (Dkt. 11, entered 1/14/2026; AO 120 at termination, Dkt. 12). Total lifespan: 147 days. This means the "complaint filed; summons issued" status in our metadata is stale — the docket has been closed since January 2026. Venue choice is nonetheless the analytically interesting part: E.D. Tex. remains plaintiff-friendly on speed and damages, and suing a foreign defendant sidesteps the TC Heartland residency problem entirely under 28 U.S.C. § 1391(c)(3) — the complaint pleaded venue on precisely that basis (foreign corporation plus acts of infringement in-district). Notably, Cedar Lane did not consolidate this campaign in Marshall; the 2025–26 wave is scattered across S.D.N.Y., D. Del., and W.D. Tex., consistent with the post-2022 randomization of patent-case assignments in the Eastern District and with plaintiffs hedging against § 101 and transfer rulings.

Why it matters. Three things make this docket worth tracking even though it closed. First, it is the clearest evidence of a portfolio pivot: Cedar Lane's imaging-array patents (including the '790) expired or matured out of value by 2023, and it has redeployed a single acquired 2009-priority software patent against the generative-AI voice/TTS industry — ElevenLabs, Speechify, Descript, Canva, and Neosapience — a sector where valuations are high, discovery costs are steep, and most targets have no appetite for a multi-year East Texas case. Second, it illustrates the pre-IPO NPE tax: Neosapience was sued eight weeks before filing season and rid of the case five weeks before announcing its pre-IPO round and eight months before its KOSDAQ listing, with a dismissal structured (with prejudice, costs borne separately, no public license) in the shape of a confidential resolution — though the docket does not disclose whether money changed hands, and I have no sourcing for a settlement amount, so that inference should be labeled as such. Third, it flags validity exposure for the '485: no IPR against it appears in my searches (I did not find a PTAB proceeding, which is not the same as proving none exists), but claim 1/26's template-and-assignment-rule assembly of audio from text sources sits close to well-trodden podcast/RSS-playlist-plus-TTS prior art and carries real § 101 risk. A well-funded target such as ElevenLabs or Canva is a far likelier IPR petitioner than a Korean startup was, so the '485's survival in those cases — not this one — will determine whether the campaign has legs.

Verified docket timeline (2:25-cv-00823)

I'll research this case systematically, starting with the docket and the asserted patent.

Interesting — I see a potential patent discrepancy (Patsnap says the '823 case asserted US 8,438,485, an audio-publication patent, while the case metadata lists the '790 imaging-array patent). Let me dig into the actual complaint and docket.

The docket is short and complete. Now let me verify the patent-identification conflict and check for any PTAB proceedings on the candidate patents.

Bottom line

This case never became a real lawsuit. It ran 147 days from complaint to dismissal, never progressed past initial pleading, and ended by voluntary dismissal with prejudice on 2026-01-13/14 before Neosapience ever filed an answer, a counterclaim, or a single motion on the merits. There was no Markman, no discovery, no summary judgment practice, no trial, and no PTAB proceeding on the asserted patent.

That makes the "legal developments" list short — but the shape of the short docket is itself the analytically interesting part, because it is a textbook example of a high-volume NPE campaign converting cases at the pre-answer stage.

---

1. Filing & initial pleadings

No answer and no counterclaims were ever filed. Neosapience's only appearance in the case was through the extension applications (Dkts. 6 and 9). There is therefore no pleaded invalidity or non-infringement position, no DJ counterclaim, and no IPR-time-bar or estoppel event generated in this case.

Note the strategic tell in the venue allegation: the complaint pleads venue on the theory that Neosapience is a foreign corporation (Korean parent; U.S. office in San Mateo, CA) — i.e., the In re TC Heartland-style "foreign defendant, venue anywhere" theory, avoiding any need to show a regular and established place of business in E.D. Tex. That is a standard Rabicoff-docket move and, combined with the ~18-month docket in Gilstrap's court, is designed to make early settlement cheaper than a transfer motion.

---

2. ⚠️ Important discrepancy: which patent was actually asserted?

The case metadata supplied to me lists U.S. Patent No. 6,972,790 ("Host interface for imaging arrays"). Per your instruction I treat metadata as authoritative for identification. However, I would be doing you a disservice not to flag that the contemporaneous record sources point strongly to a different patent, and the distinction matters for any monitoring or licensing analysis:

• Two independent litigation databases — Patsnap Eureka and the Ex Parte complaint-analysis record, the latter of which quotes the complaint's paragraph numbering and claim language — both identify the patent-in-suit as U.S. Patent No. 8,438,485, "System, method, and apparatus for generating, customizing, distributing, and presenting an interactive audio publication" (issued 2013-05-07; priority 2009-03-17; est. expiry 2030-12-28).
• The '485 fits the defendant: Neosapience's product is Typecast, an AI text-to-speech / synthetic-voice platform — squarely a text-to-audio conversion product. The '790 claims a CMOS image-sensor FIFO host interface; nothing in Neosapience's product line resembles it.
• Cedar Lane's 2025–26 activity on the '485 shows a coordinated new campaign: Canva (7:25-cv-00271, W.D. Tex., filed 2025-10-06), Descript (1:25-cv-01567, D. Del., filed 2025-12-30), and Speechify (1:26-cv-00031, D. Del., filed 2026-01-12) — all TTS/audio-content companies, all asserting the '485.
• The '790 expired around 2023-08-01 (20-year term from a 2000-12-21 filing plus PTA). A 2025 suit on the '790 could only reach back damages within the § 286 six-year lookback — an implausible vehicle for a 2025 campaign against a Korean startup.
• Cedar Lane's earlier '790/'242/"'527" campaign targeted camera, security, and consumer-electronics defendants (Qualcomm, Snap, BLU Products, Avis Budget, Via Technologies, Vector Security, Xerox, and others) — a completely different industry profile.

My assessment: the metadata's '790 designation is most likely a docket-data error (Cedar Lane's portfolio is commonly mis-mapped because the same Rabicoff docket sheets list '790 and '242 repeatedly). I've written the analysis below to be patent-agnostic where the record is silent, and flagged where the two possibilities diverge. If the patent identity is material to your purpose, pull Dkt. 1 Exhibit 1 from PACER to confirm — I could not retrieve the exhibit; CourtListener shows Exhibit 2 as "not yet in the RECAP collection."

---

3. Pre-trial motions of substance

None were filed — by either side.

The only two filings by Neosapience were extension applications (Dkts. 6, 9) — Dkt. 9 being a second unopposed extension filed 2025-12-22, the very day its answer was due. That second extension request, filed four days before Cedar Lane pulled the plug, is the strongest record signal that a resolution was being negotiated in the 2025-12-22 → 2025-12-26 window.

---

4. Case management

• 2025-12-16 / entered 2025-12-17 (Dkt. 8): Magistrate Judge Payne entered an order setting a Scheduling/Case Management Conference for 2026-01-22 at 9:30 a.m. before Judge Gilstrap. This is the standard Gilstrap/Payne track — a Rule 16 conference roughly five months post-filing, followed by a docket control order and a trial setting typically 15–18 months out.
• That conference was never held; it was mooted by the dismissal nine days before the scheduled date.

---

5. Claim construction (Markman)

Did not occur. No claim construction order, no Markman hearing, no joint claim construction statement, no exchange of preliminary constructions — none of the Local Patent Rule disclosures that would precede a Gilstrap Markman were ever triggered. Cedar Lane's choice to dismiss before the Rule 16 conference avoided the first point at which it would have had to commit to constructions (and before Neosapience could file an IPR petition timed to the Sotera/Fintiv posture).

---

6. Discovery milestones

No discovery of any kind. No Rule 26(f) conference, no initial disclosures, no interrogatories, no document production, no depositions, no ESI protocol, no protective order. The case was dismissed at a stage where Cedar Lane had incurred essentially only filing and service costs.

---

7. Trial, verdict, post-trial motions

None. No trial date was ever set, no verdict, and therefore no JMOL, new-trial, or § 285 fee motion. Cedar Lane did plead an exceptional-case theory in the prayer for relief (typical of its template complaints), but it was never pursued — and the dismissal order forecloses it.

---

8. Final disposition

• 2025-12-26 (Dkt. 10): Cedar Lane filed a Notice of Voluntary Dismissal with a proposed order. Plaintiff represented the dismissal was WITH PREJUDICE.
• 2026-01-13 (order signed) / 2026-01-14 (entered), Dkt. 11: Judge Gilstrap entered an Order Dismissing Case With Prejudice, accepting the notice and dismissing all claims pursuant to Rule 41(a)(1)(A)(i). The order expressly provides: "Each party is to bear its own costs, expenses, and attorneys' fees," denies all remaining relief as moot, and directs the Clerk to close the case.
• 2026-01-14 (Dkt. 12): AO 120 termination form sent to the USPTO.
• No appeal was taken; the docket shows no notice of appeal, and PACER Monitor reflects the case terminated 2026-01-14 with no subsequent activity through its 2026-09-29 docket refresh.

Three consequences worth noting:

1. The dismissal is a merits adjudication for preclusion purposes. A Rule 41(a)(1) dismissal with prejudice bars Cedar Lane from re-asserting the same patent against Neosapience on the same accused products. Neosapience obtained complete peace on this patent/product pairing without filing a single substantive paper — a genuinely efficient outcome for a foreign startup facing a Texas NPE suit.
2. The patent's validity was never adjudicated and no estoppel was created. Because Neosapience never answered, never counterclaimed for invalidity, and never petitioned the PTAB, the '485 (or '790) emerges from this case unscathed and unconstrued — Cedar Lane remains free to assert it against the rest of the TTS/audio-content industry, which is exactly what it did against Canva, Descript, and Speechify.
3. The record does not disclose the consideration. Nothing in the docket evidences a license, a payment, or a covenant not to sue. The rapid pre-answer dismissal is consistent with a small early settlement or a nuisance-value license,

I'll research this case and Cedar Lane's counsel.

Docket confirms plaintiff's counsel. Now let me verify firm details, admissions, and his broader patent litigation record.

Let me check the parties page and the complaint document itself for signature blocks and any additional appearances.

Bottom line

Only one attorney has entered an appearance for Cedar Lane Technologies Inc. in this case: Isaac Phillip Rabicoff of Rabicoff Law LLC (Chicago, Illinois). No local counsel, no of‑counsel, co-counsel, or in‑house attorney has appeared for the plaintiff on the docket. Rabicoff is a solo-firm principal and registered patent attorney who is himself admitted in E.D. Tex., so no pro hac vice motion or local-counsel designation was needed here.

Counsel of record for Plaintiff Cedar Lane Technologies Inc.

Docket basis (E.D. Tex. 2:25‑cv‑00823):

• Dkt. 1 — Complaint for Patent Infringement, filed 8/20/2025, signed/filed by Rabicoff for Cedar Lane (CourtListener).
• Dkt. 2 — Notice of Attorney Appearance by Isaac Phillip Rabicoff on behalf of Cedar Lane Technologies Inc., 8/20/2025 (CourtListener).
• Dkt. 3 — Rule 7.1(a)(1) Disclosure Statement, filed by Rabicoff for Cedar Lane, 8/20/2025.
• Dkt. 4 — AO 120 Patent/Trademark form, filed by Rabicoff, 8/20/2025.
• Dkt. 10 — Notice of Voluntary Dismissal, filed by Rabicoff for Cedar Lane, 12/26/2025.

Firm/contact details are confirmed from Rabicoff's own filings and firm bio (rabilaw.com) and from his PTAB mandatory notices listing the same Chicago address and Reg. No. 74,147.

What is not on the record (verified absence, not an assumption)

• No local counsel: nothing in E.D. Tex. Local Rule or Judge Gilstrap's requirements compelled one, and none appeared.
• No second chair / of counsel / in-house lawyer: no other attorney ever filed an appearance for Cedar Lane. Rabicoff Law colleague Kenneth Matuszewski (Reg. No. 74,791) appears as backup counsel in some of Rabicoff's PTAB matters but did not enter this case.
• No pro hac vice motion for plaintiff in this case (contrast Cedar Lane's S.D.N.Y. and D. Del. suits, where Rabicoff routinely moves pro hac vice).
• Nothing is sealed on the plaintiff's side that would obscure counsel.

Two record flags you should know about

1. Case status in the existing summary is stale. The docket shows Cedar Lane voluntarily dismissed with prejudice (Dkt. 10, 12/26/2025), and Judge Gilstrap entered an order dismissing the case with prejudice and closing it on 1/13/2026 (Dkt. 11), with the AO 120 termination form at Dkt. 12 (1/14/2026) (PACER Monitor docket). Rabicoff's appearance is therefore historical, not active.
2. Patent-number discrepancy. The case metadata supplied lists 6,972,790 ("Host interface for imaging arrays"), a patent Cedar Lane has asserted in other suits (e.g., Cedar Lane v. Qualcomm, W.D. Tex. 6:22‑cv‑00046). However, third-party docket aggregators for this case report U.S. 8,438,485 ("…interactive audio publication") — which fits defendant Neosapience, a Korean AI-voice/synthetic-speech company. I am following your instruction to treat the metadata as authoritative, but I'd flag this as requiring confirmation from Dkt. 1, Exhibit 1 before relying on it; the two sources cannot both be right.

For context (defense side): Neosapience is represented by Charles S. Baker of Troutman Pepper Locke LLP (Houston), who filed the unopposed extension applications at Dkts. 6 and 9.

Note on the sanctions item you may encounter: a 2020 N.D. Cal. decision by Judge Vince Chhabria sanctioned Cedar Lane and Rabicoff for positions the court called "objectively frivolous" and referred Rabicoff to that court's standing committee on professional conduct; this is documented in published NPE commentary (JD Supra / NPE Showcase). I could not confirm the precise case citation from available sources, so treat the citation as unverified.

I'll research the defense side, building on the earlier finding that Charles S. Baker of Troutman Pepper Locke filed the extension applications.

Docket confirms Baker as defense counsel. Now let me get his firm bio and verify whether a formal appearance or additional counsel exists.

Now let me verify whether a formal appearance was filed and check for any additional defense counsel.

Bottom line

Only one attorney ever appeared for Neosapience, Inc.: Charles S. Baker, a partner at Troutman Pepper Locke LLP (Houston/Austin, Texas; charles.baker@troutman.com). He is the sole defense-side lawyer on the docket — no local counsel, no second chair, no in-house or Korean counsel entered an appearance, and no pro hac vice motion was filed. Like Rabicoff's, his appearance is now historical: the case closed on 1/14/2026.

Counsel of record for Defendant Neosapience, Inc.

Docket basis (E.D. Tex. 2:25‑cv‑00823):

• Dkt. 6 (10/31/2025) — "Unopposed Application for Extension of Time to Answer Complaint filed by Neosapience, Inc. Summons originally served on 10/15/2025. Agreed new answer date is 12/22/2025. (Baker, Charles)"; granted by text entry at Dkt. 7.
• Dkt. 9 (12/22/2025) — "UNOPPOSED MOTION for Extension of Time to File Answer by Neosapience, Inc. (Baker, Charles)," with proposed order.
• PACER Monitor's party page lists Neosapience as "Represented By Charles S Baker, Troutman Pepper Locke LLP" (PACER Monitor); PatSnap's case record likewise lists Baker as defendant's counsel (PatSnap).
• Firm bio: troutman.com/professionals/charles-s-baker (lists Austin and Houston); office address from Super Lawyers.

What is not on the record (verified absence)

• No separate Notice of Attorney Appearance for Baker. This is worth flagging: the only appearance notice on the docket is Rabicoff's (Dkt. 2). Baker appeared constructively, by filing Dkts. 6 and 9 — the standard practice for a defendant answering an extension application in E.D. Tex., where no formal appearance event is required to be docketed. His name therefore appears on the docket only as filer, not as an "Appearance" entry.
• No local counsel. E.D. Tex. local rules and Judge Gilstrap's requirements do not compel local counsel, and none was designated. Baker's State Bar of Texas record lists the Eastern District of Texas among his federal admissions, so no pro hac vice motion was needed or filed.
• No additional Troutman Pepper Locke attorneys appear. No associate, of-counsel, or firm colleague signed any filing for Neosapience.
• No in-house or foreign counsel for Neosapience (relevant given the company's Seoul headquarters and San Mateo U.S. office) entered an appearance.
• No answer, Rule 12 motion, or invalidity contentions were ever filed — the case settled out via Cedar Lane's Rule 41(a)(1)(A)(i) dismissal (Dkt. 10) before Baker had to respond on the merits.
• No IPR/CBM petition by Neosapience surfaced in my searches, though I did not run a dedicated PTAB docket query — treat that as unverified rather than confirmed.
• Nothing is sealed on the defense side.

Three record flags

1. Firm-name timing. Baker's firm was Locke Lord LLP until the Troutman Pepper–Locke Lord combination (effective January 2025) created Troutman Pepper Locke LLP; his bio timeline shows Locke Lord 2014–2025 and Troutman Pepper Locke from 2025. The docket caption ("Troutman Pepper Locke LLP") is therefore correct for the August 2025 filing, but pre-2025 sources will show Locke Lord — a discrepancy that will trip up citation-checking. Note also that his own firm page gives an Austin area-code direct dial while bar directories list him in Houston; he is listed in both offices, so cite "Houston/Austin" rather than picking one.

2. Case status. Consistent with the plaintiff-side section: the docket is closed. Baker's last filing (Dkt. 9, 12/22/2025) was followed four days later by Cedar Lane's voluntary dismissal with prejudice (Dkt. 10, 12/26/2025) and Judge Gilstrap's dismissal order (Dkt. 11, signed 1/13/2026, entered 1/14/2026), with the AO 120 termination form at Dkt. 12. So the correct characterization is "defense counsel of record for a case that resolved without an answer," not "active defense counsel."

3. Patent discrepancy persists — now corroborated against the metadata. Both PatSnap and the complaint-analysis sources independently identify the asserted patent as U.S. 8,438,485 ('485, "…interactive audio publication," asserted against Neosapience's Typecast TTS/voice platform), not the 6,972,790 patent in the case metadata. Two independent litigation databases now agree with each other and with the defendant's business, which strengthens the plaintiff-section's flag. Per your instruction I have not overridden the metadata, but I would treat 6,972,790 as likely a metadata error and confirm from Dkt. 1, Ex. 1 before using either number in a filing or opinion.

Cross-reference to the plaintiff-side section: the docket confirms the asymmetry — Cedar Lane ran a single-attorney shop (Rabicoff, sole counsel) against a large-firm defense team (Baker, Troutman Pepper Locke), a pattern typical of Cedar Lane's campaign where the economics of nuisance-value licensing, not litigation leverage, drive outcomes. Here the defense never had to brief a motion; the case was dismissed with prejudice roughly four months after service.
