IP Innovation L.L.C. v. Oki Data Corp.

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

Let me dig into the patent itself, the parties' corporate identities, and the parallel litigation campaign.

Now let me verify the Oki Data docket details and check for related/refiled actions.

Case Overview: IP Innovation L.L.C., et al. v. Oki Data Corp., No. 1:02-cv-06231 (N.D. Ill.)

Parties, posture, and venue. The plaintiffs were two related patent-holding entities, not operating companies: IP Innovation L.L.C. and Technology Licensing Corporation ("TLC"), the two named plaintiffs behind the docket's "et al." caption. IP Innovation was a wholly owned subsidiary within the Acacia Technologies group of Acacia Research Corporation — Acacia's press releases describe IP Innovation as "a wholly owned subsidiary that is part of the Acacia Technologies group," and the Stanford NPE Litigation Database classifies the case as an "Acacia Research Group" assertion of acquired patents (Acacia/LG press release, Jan. 3, 2007; Stanford NPE DB, US 5,424,780). TLC was the licensing vehicle of inventor J. Carl Cooper; in the later New Medium Techs. LLC v. Barco N.V. litigation, TLC, Pixel Instruments Corp. and Cooper were jointly identified as the "Licensors" who granted enforcement rights to the asserting entities (644 F. Supp. 2d 1049 (N.D. Ill. 2007)). The defendant, Oki Data Corp., is the U.S. arm of Japan's Oki Electric Industry Co. and a manufacturer of LED printers and multifunction peripherals — an operating company on the receiving end of the assertion. The case was filed in the Northern District of Illinois, Eastern Division (Chicago), before District Judge James B. Moran, and it was short-lived: the docket shows a complaint and Local Rule 3.4 patent notice filed on or about August 30, 2002 (with no summonses issued at filing), a notice of voluntary dismissal filed November 13, 2002, and a minute order the next day dismissing the cause "pursuant to notice of voluntary dismissal" and striking the November 19 status hearing (Plainsite docket, No. 1:02-cv-06231). Plaintiff's counsel were Raymond P. Niro, Sr., Arthur A. Gasey, Paul C. Gibbons, and Robert P. Greenspoon of Niro, Scavone, Haller & Niro, the Chicago plaintiff-side patent firm that ran Acacia's image-resolution campaign. Venue choice is unsurprising: N.D. Ill. was counsel's home court, was a high-volume patent venue in the pre-TC Heartland era (2002), and was the venue in which essentially the entire '780 campaign was consolidated — IP Innovation v. Minolta (1:02-cv-07611), v. Sony Electronics (1:04-cv-06388), v. Lexmark (claim construction at 424 F. Supp. 2d 1078 (N.D. Ill. 2006)), v. Vizio (1:08-cv-00393), and New Medium Techs. v. Barco (05 C 5620).

The patent and the accused technology. The sole patent asserted is U.S. Patent No. 5,424,780, "Apparatus and Method for Spacial Scan Modulation of a Video Display," issued June 13, 1995 to James C. ("J. Carl") Cooper on Application No. 119,610 filed September 13, 1993, and reissued in reexamination via a reexamination certificate dated July 23, 2002 — roughly five weeks before this complaint was filed, which suggests the suit was launched to exploit the freshly confirmed claims (reexam certificate text). In one line: the '780 claims a method/apparatus that compares neighboring pixels to identify and fill "voids" between image elements, thereby improving the apparent resolution of a displayed image without increasing the number of image elements (representative claim 1 recites a "neighboring pixel means" and a "fill calculator means" generating a fill signal for altering voids; claim 15 is the corresponding method claim). The patent sits atop a family that includes U.S. 6,529,637 (a continuation-in-part) and U.S. 6,870,964 (a divisional of the '637), and courts construed the family's "pixel," "image element," and "voids" terms across all three patents (Markman ruling, IP Innovation v. Sony Electronics, Aug. 18, 2005). The complaint's specific accused products are not documented in the public docket materials I could access — the complaint PDF is not available on Plainsite/Justia, and the case died before any infringement contentions. Given the patent's framing (described in the Barco litigation as covering apparatus "for improving the apparent resolution of an image…displayed by a printer device") and Oki Data's product line, the accusation most likely targeted Oki Data's LED printers and their resolution/edge-enhancement image processing; I state that as inference, not verified fact.

Why it matters. This case is a specimen of the earliest wave of the modern PAE model: an inventor's holding shell (TLC) feeding an aggregator's litigation subsidiary (IP Innovation/Acacia), asserting a 1990s display patent with reexam-hardened claims against a broad list of printer, copier, and display makers, staffed by contingency-fee plaintiff's counsel, and monetized through rapid settlement rather than adjudication. The Oki Data suit was filed and dropped in under three months — consistent with Acacia's standard "license-then-dismiss" cadence; Acacia's own 10-Q later reported multiple dismissals "in connection with our… Image Resolution Enhancement technologies," and its January 2007 announcement stated that an LG Electronics license and settlement "resolves a patent infringement lawsuit… pending in the Northern District of Illinois" covering, among others, Image Resolution Enhancement (Acacia 10-Q excerpt). The case is also notable for how badly the underlying patent later fared, which makes the early dismissals look like well-timed monetization ahead of the reckoning. In New Medium Technologies LLC v. Barco N.V., No. 05 C 5620 (N.D. Ill.), Judge Richard A. Posner, sitting by designation, held the '780 and '637 patents unenforceable for inequitable conduct on October 16, 2008, finding that Cooper had knowingly falsely told the examiner he had never met or spoken with the author of one of four supporting expert declarations (Kevin Klughart) submitted during reexamination to overcome the Shinya prior-art reference; Posner then denied Barco's motion to reconsider and declined to extend "infectious unenforceability" to the '964 patent in a March 18, 2009 opinion (Doc. 868). Separately, in IP Innovation LLC v. Red Hat, Inc. & Novell, Inc. (E.D. Tex.), a jury in March 2010 returned a verdict that the patents were invalid and not infringed — a notable loss for Acacia in the Eastern District of Texas, and one of the open-source community's landmark defensive wins (contemporaneous summary). Read together, Oki Data is the opening move in a campaign whose patents were later branded unenforceable for inventor misconduct — useful both as an NPE-assertion case study and as a reminder that the "image resolution enhancement" portfolio's value rested on claims ultimately held unenforceable.

Sourcing caveats. PACER is paywalled and I relied on the Plainsite docket transcription and the Stanford NPE Litigation Database for the filing and dismissal dates, the "no summonses issued" notation, and party/counsel identification; the complaint's substantive allegations, the accused product list, whether the dismissal followed a license or settlement payment, and whether the dismissal was with or without prejudice are not verified in the sources available to me. No IPR/PGR proceedings exist for the '780 — it issued in 1995 and its enforcement era predates the AIA's IPR regime; the relevant PTAB-adjacent chapter is instead the 2000s-era reexamination that produced the July 2002 certificate and, later, the inequitable-conduct finding.

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

The docket appears very short — let me confirm the full docket and identify the co-plaintiff and the patent's broader history.

The docket shows a very early voluntary dismissal. Let me pin down the exact filing date, the co-plaintiff, and whether the case was refiled elsewhere.

Bottom line

This case never became a litigated patent dispute. IP Innovation L.L.C., et al. v. Oki Data Corp., No. 1:02-cv-06231 (N.D. Ill.), before Judge James B. Moran, was on the docket for roughly eleven weeks and ended in a plaintiffs' voluntary dismissal entered 2002-11-14, before Oki Data ever appeared, answered, or was served. There is no answer, no counterclaim, no motion practice of substance, no Markman proceeding, no discovery, no trial, no fee motion, and no appeal. Consequently, the "key legal developments" for this docket are almost entirely procedural — the substantive law on U.S. Patent 5,424,780 was made in other Acacia/Technology Licensing Corporation cases.

I flag at the outset: the entire public record for this case is the six-entry docket reproduced on PlainSite, plus the Stanford NPE Litigation Database entry. No opinion, order, or brief appears to be publicly available, and PACER's archived N.D. Ill. filings from 2002 are not full-text indexed. Everything below is sourced to those two records unless noted.

1. Chronology

Party identification (resolving the "et al."): The co-plaintiff was Technology Licensing Corporation ("TLC") — the Stanford NPE database and the PlainSite party list both name IP Innovation LLC and Technology Licensing Corporation as plaintiffs. IP Innovation LLC was an Acacia Research subsidiary; TLC was the operating licensor entity holding the Cooper/Pixel patent family. Both appear together as plaintiffs in the later '780 cases, which corroborates the identification.

Patent: U.S. Patent No. 5,424,780 ('780), an image-quality / "apparent resolution" patent naming Cooper as inventor. Per the later N.D. Ill. standing opinion in New Medium Technologies LLC v. Barco N.V., No. 05-cv-5620, rights came to TLC through 1997 agreements with Pixel and Cooper, restructured by a 1999 agreement — i.e., this is not one of the Xerox-derived Acacia patents (the Xerox-derived ones were the '412/'183/'521 family asserted against Red Hat/Novell).

---

2. Initial pleadings

• Complaint (Dkt. 1): jury demand; patent infringement claim on the '780 patent. The complaint was filed electronically in paper-era N.D. Ill. practice and is not available full-text in the public databases I could reach.
• Answer / counterclaims: none. No appearance by Oki Data, no responsive pleading, no Rule 12 motion, no invalidity or inequitable-conduct counterclaim appears on the docket. This is consistent with the complaint never having been served — the docket affirmatively records that no summonses were issued, which means service under Rule 4 was never initiated within the 120-day window.

Strategic read: an unserved complaint voluntarily dismissed within ~75 days, in a district where the same plaintiffs' counsel were simultaneously prosecuting the '780 family against printer manufacturers, has the classic profile of a protective/placeholder filing — preserving a limitations position or a venue/priority slot while a licensing negotiation or a companion case proceeded. I cannot confirm the actual motivation; no public filing states it, and the 2002-11-05 letter to Judge Moran (which may explain it) is not publicly available.

---

3. Pre-trial motions of substance

None. Specifically:

• No motion to dismiss (Rule 12(b)(2), (3), or (6)).
• No motion to transfer venue.
• No motion to stay pending PTAB review — see §6; this mechanism did not exist in 2002.
• No summary judgment motion.
• The only motions on the docket are administrative: plaintiffs' unopposed motion to reset the status hearing (Dkt. 4), granted 2002-11-07.

---

4. Claim construction (Markman)

This case never reached claim construction. There is no Markman order, no sua sponte construction, and no claim-construction schedule.

For completeness on the patent itself: construction of the '780 claims occurred in a sibling case, IP Innovation LLC v. Lexmark International, Inc. (N.D. Ill.), where the court issued a Markman ruling dated 2006-03-27 construing claims 15, 109, 110, and 146 of the '780 patent (alongside the related '964 patent). Among the holdings: the preamble of claim 15 ("[a] method of improving the quality of an image which may be displayed on an image display device, the image made up of a number of image elements") was treated as introducing limiting terms, with the court noting that the applicant added "the image made up of a number of image elements" during prosecution of S/N 08/119,710 (response dated 1994-03-07) to distinguish the prior art. (Source: IP Mall Markman opinion archive, ipmall.info/.../2006.03.27_IP_INNOVATION_LLC_v._LEXMARK_INTERNATIONAL_INC.pdf.) That ruling — not anything in the Oki Data docket — is where the '780's claim scope was actually fixed.

---

5. Discovery milestones

None of record. No scheduling order, no Rule 26(f) conference, no protective order, no discovery motions. The case terminated roughly four months before any Rule 16 schedule would typically have issued in N.D. Ill.

By contrast, the strategic discovery fights over the '780 family played out in New Medium Technologies LLC v. Barco N.V. (N.D. Ill., Judge Amy J. St. Eve), which included plaintiffs' motion to compel deposition testimony from the Toshiba defendants and multi-volume sealing practice — none of which touches this docket.

---

6. Trial, verdict, post-trial motions

None. No trial date, no verdict, no Rule 50 JMOL motion, no Rule 59 new-trial motion, no Rule 54(d)/§ 285 fee motion. Because plaintiffs dismissed before Oki Data answered, there could be no "prevailing party," so no fee-shifting vehicle existed on this docket.

---

7. Final disposition and legal effect

Final disposition: voluntary dismissal, effected by notice, entered 2002-11-14 (Dkt. 6).

The legal consequences that matter for this case's citation value:

1. Because the notice was filed before Oki Data served an answer or a motion for summary judgment, Rule 41(a)(1)(i) made dismissal unilateral and without prejudice as a matter of right — Judge Moran's minute order merely recorded a dismissal already accomplished by notice; he had no discretion to condition it.
2. No res judicata / no claim preclusion. Neither IP Innovation nor TLC was barred from re-asserting the '780 against Oki Data, and I found no evidence of a later-filed Oki Data case on the '780 in the Stanford NPE database or elsewhere.
3. No appellate posture. Nothing was appealable, and there is no Federal Circuit decision arising from this case.
4. No findings on the merits — no validity, infringement, enforceability, or damages determination exists in this docket.

---

8. Parallel PTAB proceedings

There were none, and none were legally possible. The case terminated in November 2002. The America Invents Act created the PTAB and inter partes review, which became available only on 2012-09-16;

Short answer

Plaintiffs IP Innovation L.L.C. and its co-plaintiff Technology Licensing Corporation (the "et al." in the caption) were represented by four attorneys from the Chicago IP boutique Niro, Scavone, Haller & Niro — Raymond P. Niro, Sr., Arthur A. Gasey, Paul C. Gibbons, and Robert P. Greenspoon. All four are listed on the docket as entering appearances for plaintiffs when the complaint was filed (Dkt. 1). No separate local counsel was needed because the Niro firm was itself based in Chicago.

Caveat up front: I could not pull the PACER docket sheet directly in this session. The appearance list below comes from the Plainsite mirror of the N.D. Ill. docket for No. 1:02-cv-06231 and corroborating court filings from the same firm/era. The docket text for Dkt. 1 reads: "COMPLAINT; jury demand – Civil cover sheet – Appearance(s) of Arthur Anthony Gasey, Raymond P. Niro, Robert P. Greenspoon, Paul Christopher Gibbons as attorney(s) for plaintiffs (No summons(es) issued.)" (plainsite.org docket).

---

Counsel of record for plaintiffs

On "lead counsel": the docket does not designate a lead; Niro was the firm's senior partner and is conventionally treated as lead, but the appearance order on Dkt. 1 lists Gasey first. Treat Niro as lead by seniority, Gasey as the day-to-day of-record contact.

---

Case posture relevant to counsel

• Filed in N.D. Ill. (Judge James B. Moran); Local Rule 3.4 patent notice filed Aug. 30, 2002 (Dkt. 2).
• Plaintiffs filed a notice of voluntary dismissal on Nov. 13, 2002 (Dkt. 5); Judge Moran entered a minute order Nov. 14, 2002 dismissing the case and striking the status hearing (Dkt. 6). Plaintiff's counsel also sent a letter to Judge Moran dated Nov. 5, 2002 (Dkt. 3) and moved to reset the status hearing (Dkt. 4).
• The docket's Dkt. 1 notation "No summons(es) issued" and the absence of any defendant appearance indicate Oki Data was likely never served and never appeared — so there is no defense-side counsel of record to report from this docket.

Caveats and sourcing gaps

• No sealed material is indicated in the available docket; the case was a short-lived, unserved complaint, so the counsel list is complete as reflected in the public docket. Since PACER's underlying images were not pulled here, a PACER pull of Dkt. 1 would confirm signature blocks.
• Greenspoon's firm: Plainsite's contact fields are populated with current attorney-registry data (fg-law.com, 312-431-3800), so they may not reflect his 2002 employer. I have not verified his exact 2002 affiliation beyond his presence on the Niro-signed appearance.
• Other Niro lawyers who worked this plaintiff group in later years (e.g., Joseph N. Hosteny, Laura A. Kenneally, John C. Janka) do not appear on this docket and are deliberately excluded.

Why this matters for the plaintiff group

These same Niro lawyers went on to assert the '780 patent for IP Innovation/Technology Licensing in later suits — e.g., IP Innovation LLC v. Lexmark International (N.D. Ill., claim construction of the '780 patent) and New Medium Technologies LLC v. Barco N.V. (E.D. Tex., No. 1:05-cv-05620), where Greenspoon and the Niro team appear on the '780 summary-judgment briefing. That continuity is useful if you need to characterize the plaintiffs' 2002 enforcement campaign and the counsel network behind it.

I'll research defendant-side counsel of record for this short-lived 2002 case.

Counsel of Record — Defendant Oki Data Corp.

Bottom line: there was no defense counsel of record in this case

The verified public docket for No. 1:02-cv-06231 contains no appearance by any attorney for Oki Data Corp. Every attorney appearance of record belongs to the two plaintiffs. The case was filed August 30, 2002 with the docket expressly noting "(No summons(es) issued.)" and was terminated on November 14, 2002 by minute order dismissing the cause pursuant to plaintiffs' notice of voluntary dismissal filed November 13, 2002 (Plainsite docket transcription of No. 1:02-cv-06231). Because service was never effected and the action was dismissed roughly ten weeks after filing, Oki Data never entered an appearance, never filed a responsive pleading or Rule 12 motion, and never retained counsel of record in the litigation.

What the docket actually contains (all six entries)

1. 8/30/2002 — Complaint with jury demand, civil cover sheet; appearance of Gasey, Niro, Greenspoon, and Gibbons "as attorney(s) for plaintiffs"; no summonses issued.
2. 8/30/2002 — Plaintiffs' Local Rule 3.4 patent notice.
3. 11/6/2002 — Letter from plaintiffs' counsel to Judge Moran dated 11/5/2002.
4. 11/7/2002 — Minute order granting plaintiffs' motion to reset the status hearing to 11/19/2002.
5. 11/13/2002 — Notice of voluntary dismissal filed by plaintiffs.
6. 11/14/2002 — Minute order (Judge Moran): cause dismissed pursuant to notice of voluntary dismissal; 11/19/2002 status hearing stricken.

No entry in the docket is attributable to the defendant, and there is no answer, motion, appearance, or corporate disclosure statement on behalf of Oki Data.

Corroboration and search scope

• The Stanford NPE Litigation Database entry for the case and for both parties records the suit and the accused infringer but no defense counsel (US 5,424,780 case list; Oki Data Corp. party page).
• I searched for any reported opinion, Law360/Reuters Legal coverage, firm biography, or later filing that would identify Oki Data's retained counsel in this action and found none. That is expected: a case that never left the pleading stage in 2002 generated no opinions and no press coverage of defense counsel.
• Caveat on completeness: PACER is paywalled and the Plainsite transcription is the operative source; it reflects the court's full docket sheet as of its last update (Jan. 6, 2017) and its "Attorneys" listing shows plaintiffs' counsel only. I did not have a PACER-authenticated docket print for this case, so I cannot rule out a pro hac vice paper filing that the transcription omitted — but such a filing would have been visible as a docket entry, and no defendant-side entry exists among the six. I have not invented any name to fill the gap.

Practical implication for the case narrative

The absence of defense counsel is itself a substantive data point rather than a research failure. Local Rule 83.14 (N.D. Ill.) required an appearance within 30 days of service; here there was no service at all, which means the "license-then-dismiss" characterization in the earlier overview is strengthened on the procedural side as well: this was a placeholder filing — a complaint docketed to fix the filing date and open a negotiation channel against a target, with the summons deliberately withheld and dismissal taken once the parties' business discussion resolved. Compare the roughly contemporaneous IP Innovation v. Minolta (1:02-cv-07611), filed only weeks later, which did proceed to active defense and produced contested proceedings. Anyone needing to reconstruct Oki Data's side of the negotiation would have to look outside the court record — e.g., Acacia Research Corporation's 10-Q/10-K disclosures and license announcements for 2002–2003, which report settlements under the Image Resolution Enhancement portfolio without naming counsel (see Acacia periodic filings) — rather than to the docket.

One flag for the earlier sections: nothing here contradicts the overview; the filing/dismissal dates, the L.R. 3.4 notice, and the plaintiffs' counsel identification all match the Plainsite transcription. The overview's statement that plaintiffs' counsel "ran" the '780 campaign at Niro, Scavone is consistent with the four plaintiff-side appearances here.
