In re: RAH Color Technologies LLC Patent Litigation

I'll research this case across multiple sources before writing the overview.

Good foundation. Now let me verify the '444 IPR outcome, the claim construction ruling, and the case's termination.

Overview

The parties. The plaintiff is RAH Color Technologies LLC, a Virginia limited liability company based in Alexandria that is wholly owned and managed by Dr. Richard A. Holub, a Ph.D. neurophysiologist and the sole named inventor across the portfolio. RAH is a non-practicing licensing entity, not an operating company: Dr. Holub developed a color-measurement/soft-proofing prototype in the mid-1990s, formed Imagicolor Corp. in 1998 to commercialize it, and — after that venture failed to raise capital — formed RAH in 2005 "as a vehicle for an on-going licensing program" (Am. Compl. ¶¶ 18–20, RAH v. Xerox, reproduced at docketalarm.com; Joint Preliminary Status Report at 1–2). RAH told the court it had signed 27 licenses averaging under $1 million each, which it used to argue the cases were proportionate, low-value disputes. The defendants are the core of the commercial graphic-arts and digital-print supply chain: Adobe Inc., Xerox Corp., Electronics For Imaging (EFI), Eastman Kodak, Dalim Software GmbH, and Heidelberger Druckmaschinen AG. Notably, EFI preempted RAH by filing a declaratory-judgment action of non-infringement in N.D. Cal. on May 7, 2018, which RAH got dismissed for lack of personal jurisdiction and which was then transferred to E.D. Va. and swept into the MDL (Joint Preliminary Status Report, § II.A; EFI v. RAH, No. 3:18-cv-07465-SI).

The technology and the asserted patent. U.S. Patent No. 8,416,444, "System for Distributing and Controlling Color Reproduction at Multiple Sites," issued in 2013 and claims priority to a Feb. 26, 1996 application (IPR2019-00628 Petition at 1). In one line: it claims a networked color-management system/computer-readable medium in which a user interface lets a user select remote "sites" (nodes with color input/output devices), store device-specific tonal transfer functions and color transformations calibrated in device-independent units, and use a gamut descriptor data structure — a two-dimensional array keyed to lightness and hue whose outputs represent saturation at the surface of a color gamut — together with an "interactive conference" capability (see claim 15 text and the PTAB's construction analysis of "sites"/"interactive conference," Dkt. 120 at 2–3). The accused instrumentalities are the defendants' ICC-profile-based color workflows: Xerox's CX Print Server, FreeFlow Core, iGen/Versant presses, MatchAssure and IntegratedPLUS; EFI's Fiery servers, Command WorkStation and Color Profiler Suite; Adobe Photoshop Creative Cloud and Acrobat Pro; Heidelberg's Prinect products (Color Toolbox, Prepress Manager); and Dalim/Kodak workflows (RAH infringement contentions as reproduced in Adobe's invalidity contentions and the Xerox complaint). RAH's theory leaned heavily on ICC v.4 compliance and use of the Perceptual Reference Medium Gamut as the claimed gamut descriptor. Asserted claims varied by defendant — e.g., claims 11, 13, 15, 18, 19, 26, 27 against Adobe; claims 11, 15, 20, 41, 42 against Xerox (claim chart, Ex. 1037, IPR2019-00627).

Procedural posture and venue. The JPML centralized the cases as MDL No. 2874, In re: RAH Color Technologies LLC Patent Litigation, No. 3:18-md-02874-SI, before Senior Judge Susan Illston in the Northern District of California, San Francisco Division (Courtroom 1, 450 Golden Gate Ave.). Pretrial Order No. 1 (Dec. 14, 2018) took in nine related color-management patents and set a Jan. 15, 2019 status conference (govinfo, USCOURTS-cand-3_19-cv-00518). Venue mattered because Adobe and EFI are headquartered in the district, because EFI's declaratory-judgment suit was first-filed there, and because the JPML wanted one judge to manage overlapping Markman and invalidity work across six defendants; Judge Illston also designated defense counsel James F. Valentine as liaison counsel for the MDL "Counterparties" (Dkt. 51). The court held a Markman hearing on Jan. 21, 2021 and issued its claim construction order the next day, construing "sites" ('870/'444), "appear substantially the same" ('870), and "interactive conference" ('444) — terms the PTAB had expressly left untouched (Dkt. 120, 3:18-cv-03277-SI). The MDL wound down by stipulated dismissal of the Adobe and Dalim cases on Sept. 27, 2021 (Dkt. 155); the docket now shows the consolidated action disposed. I could not independently confirm from a PACER pull whether every member case was formally closed, so the "terminated" status should be treated as well-supported but not PACER-verified.

Why it is notable. Three things. First, IPR linkage and a split PTAB outcome: Adobe filed four petitions on Feb. 1, 2019 — IPR2019-00627 ('008), -00628 ('444), -00629 ('897), and -00646 ('761) — and the Board divided sharply. In IPR2019-00628 the PTAB found that Adobe had not proven any of claims 11, 13, 15, 18, 19, 26, or 27 unpatentable (Final Written Decision, Aug. 31, 2020, Paper 125), while in IPR2019-00646 it invalidated claims 7, 8, 10, 11, and 13 of the '761 patent (leaving claim 15) and in IPR2019-00629 it invalidated all challenged '897 claims; Adobe then appealed the '008 and '444 decisions and RAH dropped the '897 patent from the litigation (Dkt. 120 at 2). The '444 patent thus survived a full merits attack on the very claims RAH was asserting. Second, the case is a study in NPE assertion economics against an entire industry: RAH's small, sub-$1M licensing model collided with a six-defendant MDL, and the defense's coordinated posture generated a contested real-party-in-interest discovery fight in the PTAB, where RAH won a narrowed interrogatory into Adobe's joint-defense arrangements with the other MDL defendants under the Garmin factors (PTAB Order, Dec. 12, 2019). Third, timing and damages: the patents-in-suit are expired (the '444 patent's term runs from the 1996 priority filing), which drove RAH's § 287 marking/notice arguments and EFI's successful-in-part attacks on DJ jurisdiction over non-method claims (In re RAH Color Techs., 2019 WL 2358643 (N.D. Cal. June 3, 2019)). The net result — a decade-old, expired patent family generating a multi-district, multi-IPR campaign that ended in stipulated dismissals after the marquee '444 claims survived — is a useful data point on how PTAB outcomes and patent expiry, rather than trial verdicts, set settlement leverage in PAE color-imaging litigation.

Sourcing caveat: the specific claim constructions adopted in Dkt. 120, the precise final disposition of the '008 IPR, and the Federal Circuit's disposition of Adobe's '008/'444 appeals are not confirmed in the sources I could reach; the statements above about those items are either drawn from the district court's own recital or flagged as unverified.

I'll research this multidistrict litigation thoroughly, starting with broad searches on the MDL and the asserted patents.

I have the core docket. Now let me pin down the claim construction holdings, the Federal Circuit appeals, and the various pre-trial motions.

Now the Federal Circuit outcome on the '008 and '444 appeals, plus the earlier dispositive motions.

Key Legal Developments — In re: RAH Color Technologies LLC Patent Litigation, No. 3:18-md-02874-SI (N.D. Cal., Illston, J.)

Bottom line up front: This MDL never reached trial. It was a licensing/patent-monetization campaign by a one-inventor NPE (RAH Color Technologies LLC, owned by Dr. Richard A. Holub of Rochester, N.Y.) against a coordinated group of graphic-arts and imaging vendors. The case was effectively decided in the PTAB, not the district court: Adobe's four IPRs killed the '897 and most of the '761, but the '444 patent survived intact — and the '444 was then the subject of the MDL's only contested Markman ruling before the entire MDL was dismissed by stipulation on 2021-09-27. No verdict, no damages award, no injunction, no summary-judgment ruling on the merits. The MDL was formally closed 2022-07-26.

Note on sourcing and scope: docket-level detail below is drawn from the JPML docket, the N.D. Cal. ECF entries surfaced in public aggregators, the court's claim-construction opinion, and the PTAB final written decisions. I flag explicitly the points I could not verify (principally the Federal Circuit disposition of Adobe's appeals and the individual exit dates/terms for Xerox, EFI, Kodak, and Heidelberger).

1. Filing and initial pleadings (2017-09 → 2019-04)

RAH's campaign began as a set of separate, parallel suits rather than a single action:

Two initial-pleading developments mattered strategically:

• EFI's preemptive declaratory-judgment action (2018-05-07). Rather than wait to be sued, EFI — whose products RAH was attacking through EFI's customers (Ricoh, Quad, Xerox) — filed a DJ action in N.D. Cal. seeking declarations of non-infringement of the '870, '008, '444, and '704 patents. RAH moved to dismiss for lack of personal jurisdiction and won on 2018-10-24; the case was transferred to E.D. Va. on 2018-11-14 and then swept into the MDL. This jurisdictional ruling is the reason the MDL contains a defendant-initiated DJ case rather than only RAH's affirmative suits. (Order, 3:18-cv-01612; Joint Preliminary Status Report, MDL Dkt. via Ex. 2012)
• The JPML proceeding was defendant-driven. Quad/Graphics filed the initial MDL motion on 2018-10-01 (MDL No. 2874, Pending No. 87), with argument set for 2018-11-29. The Panel issued its transfer order on 2018-12-06; Judge Illston entered Pretrial Order No. 1 on 2018-12-14 and set the initial status conference for 2019-01-15. Conditional transfer orders pulled in Dalim and Heidelberger (2019-01-17, finalized 2019-01-25) and Kodak (2019-02-13, finalized 2019-02-21). (JPML docket, MDL 2874)

Answers/counterclaims: The counterclaim posture was inverted from the start. Adobe, Xerox, EFI, Dalim, Kodak, and Heidelberger formed a common-interest/joint-defense group (verbal agreements among outside counsel dating to May 2018) and coordinated invalidity defenses. RAH later used this as the hook for its real-party-in-interest attack in the IPRs. (Adobe privilege log / interrogatory responses, 2019-05-21)

EFI's operative pleading and RAH's 12(b)(1) motion. EFI filed a second amended complaint on 2019-04-11 (MDL Dkt. 63) seeking DJ of non-infringement of the '870, '008, '444, and '704 patents. RAH moved to dismiss for lack of declaratory-judgment jurisdiction on 2019-04-18 (Dkt. 64), arguing (i) as to the '444 and '704, that EFI challenged only non-method claims on which RAH could not recover damages because RAH never marked or gave pre-expiration notice, and (ii) that EFI had not pleaded a sufficiently immediate controversy. The court applied MedImmune/Prasco and analyzed whether RAH's customer-directed enforcement (suits against Ricoh, Quad, and Xer

I'll research plaintiff's counsel across the docket, the IPR record (which often mirrors the district-court team), and firm/press sources.

Strong initial hits. Now let me confirm the local counsel role, the MDL-era team, and any changes (withdrawals/substitutions).

Plaintiff's Counsel of Record — RAH Color Technologies LLC

RAH was represented throughout by one outside firm — Global IP Law Group, LLC of Chicago (55 W. Monroe St., Suite 3400), a patent-monetization/licensing boutique — with a single Bay Area firm appearing on the N.D. Cal. docket. There is no in-house counsel of record: RAH is a one-person NPE managed by its sole inventor/owner, Dr. Richard A. Holub, who is not an attorney of record in any filing I reviewed.

Summary table

Detail

1. David Powers Berten — lead counsel (district court). The N.D. Cal. docket for the lead member case, RAH Color Techs. LLC v. Adobe Inc., No. 3:18-cv-03277-SI, lists Berten as "LEAD ATTORNEY," assigned 01/31/2018 — i.e., he was counsel from the filing of the original complaint, not just after consolidation. (docket sheet excerpt, IPR2019-00628 Ex. 2024) He appeared at the April 4, 2019 MDL case-management conference "in all cases" and personally explained the "R-A-H" pronunciation to Judge Illston. (MDL CMC transcript, 4/4/2019, IPR2019-00646 Ex. 1038) His own pro hac vice declaration states: "I am lead counsel for RAH Color Technologies LLC in six related matters," expressly including "In re: RAH Color Technologies LLC Patent Litigation, Case No. 3:18-md-02874-SI." (Declaration, 3/11/2019) He reports 28+ years of patent litigation and 25+ patent cases, and is admitted in N.D. Cal., N.D. Ill., W.D.N.Y., D. Colo., E.D./W.D. Mich., E.D. Wis., the Third, Seventh and Federal Circuits, and the Supreme Court. He has been RAH's/Dr. Holub's outside lawyer since at least 2009, when he was at Competition Law Group — the predecessor name of Global IP Law Group (the Kodak complaint describes "David Berten, then of Competition Law Group").

2. Dr. Irwin I. Park — lead counsel in the PTAB. Leadership was split by forum: Berten held the district-court "LEAD ATTORNEY" flag, while Park was Patent Owner's designated Lead Counsel in IPR2019-00627, -00628, -00629 and -00646. His amended mandatory notices in the '444 and '761 IPRs list him as "Lead Counsel," USPTO Reg. No. 68,865, ipark@giplg.com, with Ragnar Olson as back-up. (Amended Mandatory Notice, IPR2019-00646, 4/11/2019) He is also an attorney of record on the N.D. Cal. docket (assigned 01/31/2018) and appeared at the MDL conference, and he executed the declaration supporting RAH's '444 preliminary response ("I am counsel for Plaintiff RAH Color Technologies LLC"). He holds a doctorate and is a registered patent attorney — relevant here because RAH's IPR strategy (the RPI/joint-defense discovery motion under Garmin) was run out of the Chicago office, with Park as the face of it.

3. Alison Aubry Richards — trial team / of counsel. Docket-listed as "PRO HAC VICE" in the Adobe case (assigned 01/31/2018) and listed as counsel "Admitted Pro Hac Vice" in the PTAB notices. She was the examiner on the record in at least one high-stakes IPR deposition, cross-examining Adobe's declarant Christopher Kelley on his lack of ICC-specification experience. (IPR2019-00629 deposition transcript) She also appeared at the April 2019 MDL conference, announcing "Alison Richards for RAH Color Technologies." Title: the filings I located do not state a firm title (partner vs. of counsel), so I would not characterize her seniority beyond "member of the core trial team."

4. Ragnar Olson. USPTO Reg. No. 58,684, rolsan@giplg.com. Listed as back-up counsel in every Patent Owner mandatory notice and copied on all Patent Owner service correspondence in the four Adobe IPRs. I did not locate a separate N.D. Cal. appearance by him; treat his district-court role as unconfirmed.

5. Meagan C. Leslie. Filed "ATTORNEY Appearance for Plaintiff RAH Color Technologies LLC" in the N.D. Ill. member cases, e.g. RAH v. Dalim Software GmbH, No. 1:19-cv-00275 (Dkt. 11, 1/16/2019), and RAH v. Heidelberger — cases that were then pulled into the MDL by conditional transfer order. (Justia docket) She also appears in the aggregated MDL attorney list. She has since left the firm and is now Counsel, Legal and Licensing at Sisvel U.S. in Chicago, described as "previously … a patent litigation attorney at Global IP Law Group." (IAM speaker bio)

6. Randall G. Block — local counsel. Burke, Williams & Sorensen, LLP, 101 Howard Street, Suite 400, San Francisco; rblock@bwslaw.com; assigned 08/13/2018 in RAH v. Adobe, No. 3:18-cv-03277-SI. (docket excerpt, Ex. 2024) He is the only Northern California firm appearing for RAH, and the timing (three months after the case was filed in San Francisco) fits a local-counsel designation. Worth noting for accuracy: MDL Pretrial Order No. 1 expressly waived the L.R. 11-3 requirement that pro hac vice counsel retain local counsel (Pretrial Order #1, ¶ 9) — so Block's appearance predates and is independent of any local-counsel mandate, and I could not confirm whether he withdrew later.

Caveats and gaps (please read before relying)

• No live appearances exist. The MDL was dismissed by stipulation on 2021-09-27 (Dkt. 155) and closed 2022-07-26, so all of the above are historical appearances. The unicourt/aggregator entry for 3:18-md-02874 still lists the plaintiff-side attorneys as Berten, Richards, Park, Leslie and Block.
• I could not pull the MDL master docket (3:18-md-02874-SI) directly from PACER. The attorney designations above come from three independent sources that corroborate each other: (i) the N.D. Cal. docket sheet for member case 3:18-cv-03277-SI as captured in PTAB Exhibit 2024 (May 2019); (ii) the sworn 4/4/2019 MDL conference transcript; and (iii) the Patent Owner mandatory notices/powers of attorney filed in the four Adobe IPRs. Because the master-docket pull failed, I cannot rule out additional pro hac vice appearances for Xerox, EFI, Kodak or Heidelberger that were never mirrored on the Adobe docket.
• Not counsel of record, but relevant background: Dr. Holub's earlier representatives in the pre-suit licensing campaign were Niro, Scavone, Haller & Niro (

I'll research the counsel of record for each defendant group across the MDL and member cases.

Good initial list. Now let me map each attorney to a specific defendant.

Now the remaining defendants — Kodak, Heidelberg, Dalim — plus the local-counsel picture.

Counsel of Record — Defendants in MDL No. 2874

Bottom line: Because the MDL was structured as one consolidated pretrial proceeding with six defendant groups, each defendant retained its own firm; there was no single joint defense firm, but Perkins Coie (for Adobe/Dalim) functioned as the coordination hub and its partner James F. Valentine was appointed liaison counsel by the court. The defense bench was lean: roughly one lead firm per defendant, with out-of-state counsel appearing pro hac vice — the docket expressly notes that in this district "Parties are not required to obtain local counsel" (Dkt. 3, Pro Hac Vice notice, RAH v. Adobe, 3:18-cv-03277), so there is no separate "local counsel" tier for most defendants.

Adobe Inc. — Perkins Coie LLP (Palo Alto, CA)

Xerox Corporation — Ward Greenberg Heller & Reidy LLP (Rochester, NY)

Electronics For Imaging, Inc. — Jeffer Mangels Butler & Mitchell LLP (Irvine, CA)

Caveat on posture: EFI was the plaintiff in its own declaratory-judgment action (EFI v. RAH, 3:18-cv-07465-SI), so its counsel of record is technically plaintiff-side in that member case, though EFI is a defendant/counterparty within the MDL.

Heidelberger Druckmaschinen AG — Duane Morris LLP (Philadelphia, PA)

Dalim Software GmbH — Perkins Coie LLP (Palo Alto, CA)

Eastman Kodak Co. — NOT VERIFIED

I could not confirm Kodak's litigation counsel of record from any source I could reach. Kodak's case (RAH v. Eastman Kodak, W.D.N.Y. 6:19-cv-06112, filed 2/8/2019, then tagged into the MDL via conditional transfer order of 2/13/2019, finalized 2/21/2019) is the one member case for which no appearance, transcript, privilege log, or firm press release surfaced identifying defense counsel. Kodak's named contacts in RAH's complaint — Charles E. Snee III, Peter Cody (AGC), David Woods, and Dr. Chris Edge — were licensing/in-house correspondents, not counsel of record, and should not be described as such.

Docket names I could not map to a party (be careful with these)

The consolidated docket's attorney list (as reflected in public aggregators) also includes Randall G. Block, Thomas Mansfield Dunlap, David Eiseman IV, Tyler Robert Marandola, Patrick Shaw Salceda, and Erika N. D. Stanat — plus an aggregated note of "9 More Attorneys Available." At least one of this group very likely constitutes Kodak's defense team (and one may be in-house counsel for a corporate defendant), but I found no public filing that ties any of these names to a specific defendant or firm, so I am deliberately not assigning them. The aggregated lists on third-party sites (UniCourt and similar) also mix plaintiff counsel (Global IP Law Group: Berten, Richards, Park, Olson) and defense counsel in a single undifferentiated block — that is the main trap in this docket and is why I verified each name against a primary document (CMC transcript, complaint signature block, docket caption, or privilege log) before listing it above.

Other sourcing caveats:

• Nothing here suggests any defense appearance was sealed; the MDL's filings were public through the 9/27/2021 dismissal.
• The 4/4/2019 case-management transcript (Ex. 1038 to IPR2019-00646) is the single best primary source for defense appearances and is the backbone of the table above.
• Role characterizations ("lead" vs. "co-counsel") for Hanewicz, Liang, Harradine, and Mellema are my inferences from who signed and who was copied on filings and client correspondence, not from a formal docket "LEAD ATTORNEY" designation except where noted (Valentine and Berten are the only two carrying that docket flag in the RAH v. Adobe docket excerpt).
• Recommended confirmation step: a PACER pull of the MDL docket sheet (3:18-md-02874-SI) filtered for "Notice of Appearance" and "Pro Hac Vice" entries, plus the Kodak member case (6:19-cv-06112), would close the Kodak gap and resolve the unmapped names in under ten minutes.
