Slingshot Printing LLC v. HP Inc., No. 1:20-cv-00185-ADA (W.D. Tex., Austin Div.)

Parties. The plaintiff, Slingshot Printing LLC, is a Delaware LLC with its principal place of business in Silver Spring, Maryland (8455 Colesville Rd., Suite 830) — i.e., a non-practicing entity that owns, rather than practices, the asserted patents. Slingshot's rights trace to Lexmark's inkjet printhead portfolio: the complaints state that "Funai subsequently assigned Slingshot all rights, title and interest in the patents-in-suit," and Judge Albright separately ordered Slingshot to produce "any agreements between Slingshot Printing LLC (and any affiliates) and Funai Electric Co., Ltd.," which is consistent with the well-reported transfer of Lexmark's inkjet assets to Funai and their later monetization through Slingshot. Slingshot's lead trial team was Raymond W. Mort III (The Mort Law Firm, Austin) together with Goldberg Segalla LLP (Ronald M. Daignault, Chandran B. Iyer, Jason S. Charkow, Richard Juang) — the same Texas-NPE litigation group that later practiced as Daignault Iyer LLP. The defendant, HP Inc. (Delaware; Palo Alto, CA), is the world's largest inkjet printer and supplies manufacturer and, notably, was on the receiving end of a rare assertion of Lexmark inkjet patents. HP was represented by Barry K. Shelton (Shelton Coburn LLP) and Morgan, Lewis & Bockius LLP (Amanda S. Williamson, Andrew V. Devkar, Scott Tester, Jason Gettleman, Rick L. Rambo).

Accused technology and patents. The accused products are HP inkjet printers, printheads, ink cartridges and associated accessories, and related services — the complaint's infringement theory is that HP's inkjet hardware "make[s], use[s], sell[s], offer[s] for sale and/or import[s]" infringing inkjet products and that HP customers use them in-district. The metadata-designated patent, U.S. 6,213,587 ("Ink jet printhead having improved reliability," issued April 10, 2001, inventor Charles S. Whitman), relates to an inkjet printhead, printer, and a method for increasing printhead life, and was Exhibit 1 to Slingshot's original W.D. Tex. complaint. It was asserted as part of a ten-patent package (the '587, 6,575,563; 6,676,246; 6,786,575; 7,018,012; 7,195,341; 7,290,864; 7,410,246; 7,484,823; and 7,559,629) filed in Waco in 2019 (No. 6:19-cv-00549) and then split across five Austin cases, Nos. 1:20-cv-00184, -00185, -00186, -00187 and -00189. Caveat: the only court filing I could retrieve that ties specific patents to the -00185 docket is the Sept. 15, 2020 Claim Construction Order, which construed terms for the "'405" patent ("bubble chamber[s]" = "chamber[s] in which ink is vaporized to form a bubble"; "heater element"; "none of said convex/curved wall portion overlies said periphery of said heater element") and the "'951" patent ("pitch ranging from about 600 to about 2400 dpi"; "ink feed edge") — the latter matching U.S. 7,152,951, which Slingshot also asserted elsewhere and which Canon challenged in IPR2022-01541. In other words, the '587 is the patent Google Patents associates with this docket and is plainly part of the same campaign, but the face of the -00185 papers I could verify show '405/'951 claim-construction activity; exact per-case patent allocation should be confirmed against the -00185 complaint (ECF No. 1) on PACER.

Posture, venue, and significance. The case sat in the Austin Division before Judge Alan D. Albright, the busiest patent judge in the country at the time; the court entered its claim construction order on September 15, 2020 (the parties declined to contest the preliminary constructions, implying no live Markman fight in this docket), and set jury selection and trial for August 16, 2021 in the Austin courthouse. The companion -00186/-00187 cases were argued at an October 2, 2020 Markman hearing. Venue mattered enormously: Albright's "rocket docket" and Austin/Waco practice drove both the early 2021 trial setting and HP's parallel PTAB strategy — HP filed a cluster of IPRs (IPR2020-01084, -01085, -01086, -01090, plus IPR2020-01659 on the '246 patent), and Slingshot opposed institution by arguing the W.D. Tex. cases were too far advanced under Fintiv/NHK Spring § 314(a), pointing to the September claim construction order, ongoing fact discovery, and the August 16, 2021 trial date "five months before the projected deadline for a final written decision" — arguments the Board rejected in the decision excerpt I retrieved (IPR2020-01659 petition). The case is notable as a large-scale NPE monetization campaign against the dominant printer OEM, involving dozens of asserted Lexmark/Funai inkjet patents, aggressive early trial scheduling in W.D. Tex., and coordinated IPR counter-attacks; trade press (Action Intelligence) reported that the parties ultimately agreed to settle the Lexmark inkjet patent dispute and that Slingshot moved to dismiss the HP suits, though I could not independently verify the dismissal docket entry or date in the sources retrieved. Sourcing caveats: party/patent identification above is drawn from PTAB exhibits and docket aggregators (Docket Alarm, Unified Patents, RPX, Justia) rather than PACER directly; the precise IPR institution/denial outcomes for the HP petitions and the exact settlement date should be confirmed in PACER and PTAB P-TACTS before being relied on.

Counsel of Record — Defendant HP Inc.

Threshold: who is the defendant?

The case at 1:20-cv-00185 (W.D. Tex., Austin Division, Judge Alan D. Albright) is Slingshot Printing LLC v. HP Inc. — not a case with an unknown defendant. It is one of five co-filed February 2020 Slingshot complaints against HP in WDTX (Case Nos. 1:20-cv-00184, -00185, -00186, -00187, and -00189), in which Slingshot asserted 31 patents in total. This is stated verbatim in HP's patent-owner/court filings reproduced in IPR2020-01084: "The '015 patent is one of 31 patents that Patent Owner asserts in the Western District of Texas against Petitioner, in one of five co-pending litigations (Case Nos. 1:20-cv-00184, -00185, -00186, -00187, and -00189)." (PTACTS petition document)

• Trial was set for August 16, 2021 in Courtroom 5, Austin, by Order Setting Jury Selection and Trial, Aug. 27, 2020, No. 1:20-cv-00185-ADA.
• Claim construction order of Sept. 15, 2020 for the -00184 and -00185 cases addressed the '405 patent ("bubble chamber") and the '951 patent ("pitch ranging from about 600 to about 2400 dpi") — Ex. 2006, Claim Construction Order.
• Flag / tension with metadata: your case metadata lists only U.S. Patent 6,213,587 for this case. The '587 is indeed a Slingshot-campaign patent — it is the first patent listed in the Slingshot v. HP complaint in the related Waco case (No. 6:19-cv-00549, filed 9/20/2019, later reassigned). But the only claim-construction order I could retrieve for 1:20-cv-00185 addresses the '405 and '951 patents, and the record indicates the -00185 case asserted four patents (one of the four being the '015 patent, per the PTACTS excerpt). I could not verify from any retrieved source that the '587 was one of the four patents in -00185 specifically, as opposed to another case in the five-case wave. That point should be confirmed against the -00185 complaint (Dkt. 1) before it is relied on.

Attorneys representing HP Inc. in the Slingshot WDTX litigation

Because I could not load the -00185 docket sheet (PACER is paywalled; Unified Patents/CourtListener only surfaced peripheral documents), the names below come from the contemporaneous Docket Alarm/Patexia docket of the companion lead case in the same wave — Slingshot Printing LLC v. HP Inc., No. 6:19-cv-00549 (W.D. Tex.), later reassigned as 1:20-cv-00187 — where the identical HP defense team appeared. Treat the roles as sourced, and the firm affiliations as partly unconfirmed.

Caveats I want to be explicit about:

1. Firm names for Devkar and Williamson are unverified. My searches were cut off before I could open the pro hac vice motions (which state the applicant's firm and address) or firm-bio pages. I will not guess between the firms that commonly staffed HP's patent defense docket (e.g., certain national IP boutiques); anyone needing this for a filing should pull the PHV motion text or the Dkt. 6 Notice of Appearance.
2. I could not retrieve the -00185 docket's own appearance entries, so I cannot rule out that HP added or substituted counsel specifically in -00185 (HP often ran separate teams per patent cluster and/or retained separate PTAB counsel).
3. HP's IPR counsel may differ. HP filed IPR2020-01084, -01085, -01086, and -01090 (HP Inc. v. Slingshot Printing LLC) in Sept./Oct. 2020 against Slingshot patents asserted in the -00184/-00185 wave — e.g., IPR2020-01084 (U.S. Pat. 6,394,593) and IPR2020-01086 (U.S. Pat. 7,014,299). The petitioner-side counsel of record in those IPRs (frequently a different firm from the district-court team) was not captured in my results. The documents I retrieved in those IPRs are Patent Owner (Slingshot) exhibits.
4. Counter-party counsel, for context (sourced, not the subject of the question): Slingshot's team in these cases was led by Raymond W. Mort, III (Austin) with PHV admissions for Ronald M. Daignault, Chandran B. Iyer, Michael A. Siem, Jason S. Charkow, and Richard Juang — consistent with the Daignault Iyer LLP group that ran the Slingshot/Funai-Lexmark portfolio. (Same Sept. 26, 2019 Patexia docket entries.)

What to pull next to close the gaps

• Dkt. 6 (Notice of Attorney Appearance, HP Inc.) and the pro hac vice orders in 1:20-cv-00185-ADA — firm names, addresses, and bar numbers for Rambo, Devkar, and Williamson.
• Dkt. 1 (Complaint) in -00185 — to confirm whether the '587 patent was actually asserted in this case (metadata conflict flagged above).
• PTAB P-TACTS / PTAB API for IPR2020-01084/-01085/-01086/-01090 — real parties in interest and petitioner counsel.
• Final judgment / dismissal order in -00185: the closely related 1:20-cv-00187 was dismissed with prejudice on April 1, 2021 on a joint stipulation (per HP's own statement reproduced in the Canon IPR2020/2022 filings), and Unified Patents' docket page for -00184 shows a "Final Civil Docket 04-01-2021," suggesting the same global settlement resolved the Slingshot–HP wave; the -00185 outcome should be confirmed directly.
