Peter Henrik Pedersen v. Mailgun Technologies, Inc.

Case Overview: Pedersen v. Mailgun Technologies, Inc. (6:21-cv-01153-ADA)

Parties. Plaintiff Peter Henrik Pedersen is an individual inventor and sole owner of U.S. Patent No. 6,965,920 (the "'920 Patent"), titled "Profile Responsive Electronic Message Management System." Unified Patents describes Pedersen as "believed to be associated with AiPi Solutions," and he has pursued a broad, serial enforcement campaign against tech companies — functionally an individual-inventor/NPE-style assertion program run through Ramey LLP (William P. Ramey III, with Kyril Talanov) in W.D. Tex. (Ramey LLP has publicly touted its Pedersen suits against Blackbaud, Constant Contact, Monday.com, Wix, and Zendesk; Unified Patents' portal classifies Pedersen's entity type as "NPE (Individual)"). Defendant Mailgun Technologies, Inc. is an operating company in the email infrastructure space: a transactional-email API and delivery platform (SMTP relay, cloud message routing, and email APIs) used by developers and SaaS businesses — precisely the class of product implicated by a message-management patent. Mailgun was represented by Goodwin Procter LLP (Brett Schuman, Natasha Daughtrey) and Slayden Grubert Beard PLLC (Darryl Adams).

Asserted patent and accused technology. The sole patent in suit is U.S. Patent No. 6,965,920, issued November 15, 2005 from Application No. 09/904,270 (filed July 12, 2001), claiming priority to Provisional Application 60/217,719 (July 12, 2000). The patent is directed to a system and method for centrally specifying and managing how electronic messages from a plurality of "messengers" (senders) are distributed to individual recipients: recipients enter profile data specifying delivery parameters — "where, when and how specific types of messages from specific messengers" are delivered — while messengers enter profile data and message files via a global network, and an "individual message generator" combines the data to generate recipient-specific messages ('920 patent, col. 2, ll. 46–50; col. 11, ll. 26–50). Pedersen alleged that Mailgun's email API and message-delivery platform directly and/or indirectly infringed at least claim 1 (and dependent claims) of the '920 Patent. The parties litigated claim construction through a full Markman cycle — Mailgun's opening brief (Dkt. 22), Pedersen's response (Dkt. 23, filed 9/12/2022), reply (Dkt. 26), sur-reply (Dkt. 29), and Joint Claim Construction Statement (Dkt. 30) — with a Markman hearing on October 19, 2022, before the court issued its Claim Construction Order that same day. Mailgun contested terms including "message files," and asserted indefiniteness of method claims 8–11 and claim 12 (Pedersen countered that "message file" appears nowhere in the claims and that Mailgun was improperly importing a single specification embodiment).

Procedural posture and venue. The case was filed November 9, 2021, in the Western District of Texas, Waco Division, assigned to Judge Alan D. Albright (Case No. 6:21-cv-01153-ADA), with a jury demand. Judge Albright's Waco docket was, at the time, the most patentee-friendly venue in the country — famed for aggressive scheduling (the June 14, 2022 Scheduling Order, Dkt. 20) and a "rocket docket" that pressured early settlement. Pedersen filed a companion case against Google the same day (6:21-cv-01152-ADA, dismissed 4/25/2022) and later a wave of '920 cases against Microsoft, Yahoo/Verizon, Oracle, Adobe, Salesforce, Zoho, Intuit, Ziff Davis, Blackbaud, Constant Contact, Monday.com, Wix, Zendesk, Aurea, Upland, and others — all before Judge Albright. The case is now resolved: per PatSnap's PACER-based analysis, the parties filed a Rule 41(a)(1)(A)(ii) joint stipulation of dismissal expressly referencing a settlement agreement — Pedersen's infringement claims dismissed with prejudice, Mailgun's counterclaims dismissed without prejudice, and each side bearing its own fees. Caveat: the case metadata provided here lists the case as "Active" and the Oracle IPR mandatory-notice (June 2, 2023) still listed it "Pending," so the dismissal appears to post-date June 2023; the exact dismissal date was not independently confirmed in my sources.

Why the case is notable. This suit is a representative data point in one of the largest single-patent assertion campaigns in W.D. Tex.: a 2005-era email-messaging patent enforced against essentially every major email-marketing, CRM, and SaaS communication platform, generating systemic exposure for the email API/delivery industry. Its significance is amplified by the parallel PTAB record: Unified Patents filed IPR2023-00029, and the Board's May 10, 2024 Final Written Decision held claims 1 and 14–17 of the '920 Patent unpatentable as obvious — a decision the Federal Circuit affirmed on March 26, 2026 in Pedersen v. Unified Patents (Appeal No. 2024-2090), with the PTAB's finding of obviousness supported by substantial evidence. Additional IPRs were filed by Oracle (IPR2023-00867) and Adobe (IPR2023-00986), and the '920 litigation wave subsequently stalled through stays and dismissals (e.g., Monday.com's stay order, W.D. Tex. 6:22-cv-00923, noting the parallel Intuit/Upland/Ziff Davis cases were stayed or dismissed). The Mailgun settlement — with its asymmetric dismissal (plaintiff with prejudice, defendant's counterclaims without prejudice) and no fee award — is characteristic of the resolution pattern this campaign produced, and the case remains a cautionary example for email-infrastructure vendors of the cost of defending legacy-message-routing patents in Judge Albright's Waco division.

Based on the search results available, here is the chronological record. I flag where specific docket dates could not be confirmed from public sources.

1. Filing & Initial Pleadings

• 2021-11-09 — Complaint filed. Pedersen sued Mailgun Technologies, Inc. in the W.D. Tex. Waco Division (Case No. 6:21-cv-01153-ADA), alleging infringement of U.S. Patent No. 6,965,920 (the "'920 patent"), which covers an electronic message management system that routes/filters messages per recipient-defined delivery preferences. A jury trial was demanded. (Source: PTACTS petition exhibit — Joint Claim Construction Statement; Unified Patents Fed. Cir. briefing; Docket Navigator exhibit cited in IPR2023-00029 EX1012.)
• Counsel of record: Plaintiff was represented by William P. Ramey III (Ramey LLP) and Kyril Vladimir Talanov; Mailgun by Goodwin Procter LLP (Brett Schuman, Natasha Daughtrey) and Slayden Grubert Beard PLLC (Darryl Adams, Jesse Cheng, Kline Moore). (Source: Joint Claim Construction Statement signature block, Oct. 12, 2022; PatSnap litigation summary.)
• Answer and counterclaims. Mailgun answered and asserted counterclaims (the later dismissal stipulation expressly extinguishes "all counterclaims"), but I could not confirm the exact answer/counterclaim filing date from available sources.
• Related wave of cases: Pedersen filed a large batch of parallel WDTX actions on the same day (e.g., 6:21-cv-01152, dismissed 2022-04-25; 6:21-cv-01155 against J2 Global). The '920 patent was also asserted against Zoho, Intuit, Salesforce, Blackbaud, Constant Contact, Monday.com, Zendesk, Google, Microsoft, Yahoo, Oracle, Adobe, Wix.com, and others. (Sources: Oracle IPR2023-00867 Mandatory Notices, June 2, 2023; Unified Patents insight, Mar. 26, 2026.)

2. Pre-Trial Motions of Substance

• 2022-06-14 — Scheduling Order (Dkt. 20). Issued by Judge Albright; the claim-construction schedule flowed from it. (Source: Scheduling Order cited as EX1016 in IPR2023-00029; Joint Claim Construction Statement, ¶1.)
• Motions to dismiss / transfer / stay. I found no evidence in the available record of a Rule 12(b)(6) motion to dismiss, § 1404(a) transfer motion, or stay pending IPR in this case. The docket proceeded directly into claim construction, which is consistent with no dispositive pre-trial motion having been granted. (This is a "not confirmed in available sources" point, not a negative finding on the docket.)

3. Claim Construction (Markman) — Reached and Resolved

The case did reach claim construction, with a full briefing cycle and a Markman hearing:

• Dkt. 22 — Mailgun's Opening Claim Construction Brief (arguing "message file[s]" should be construed as "a file that contains a composed message and its recipients," and that claims 8–11 and 12 were indefinite).
• 2022-09-12 — Dkt. 23 — Pedersen's Response, arguing "message file" appears nowhere in the claims (only "message files"), that Mailgun was improperly importing a specification embodiment, and that the indefiniteness challenges failed. (Source: Docket Alarm PDF of Dkt. 23, filed 09/12/22, exhibit in Adobe IPR2023-00986.)
• Dkt. 26 (reply) and Dkt. 29 (sur-reply) — filed per the Claim Construction Order's recitation.
• 2022-10-12 — Dkt. 30 — Joint Claim Construction Statement listing four disputed terms: "message file[s]" (claim 1), "a method of inputting data into the message management system of claim 1…" (claims 8–11), "accepting…[and entering…]" (claim 8), and "wherein the messenger profile application receives and stores messenger profile data…" (claim 12) — with Mailgun pressing indefiniteness on the method/means terms. (Source: PTACTS exhibit, Joint Claim Construction Statement.)
• 2022-10-18/19 — Markman proceedings. The Court provided Preliminary Claim Constructions on Oct. 18 and held the Markman hearing on Oct. 19, 2022.
• 2022-10-19 — Claim Construction Order. Judge Albright signed a claim construction order memorializing final constructions, with a more detailed explanatory order to follow (objection deadlines stayed until that fuller order issued). (Source: Docket Alarm PDF, "Claim Construction Order," Oct. 19, 2022, exhibit in Adobe IPR2023-00986.) I could not confirm whether the fuller explanatory order ever issued before dismissal.

4. Discovery Milestones

• No specific discovery milestones (document production, depositions, expert reports, privilege disputes) were identified in the available public sources. The case appears to have been litigated through the claim-construction phase and then settled before completing fact/expert discovery or trial. I cannot verify any particular discovery event dates.

5. Trial / Post-Trial

• No trial occurred. There was no jury verdict, and therefore no JMOL, new-trial motion, or fee petition. The case was resolved by settlement and stipulated dismissal (below).

6. Final Disposition — Settlement & Stipulated Dismissal

• Joint stipulation of dismissal under Rule 41(a)(1)(A)(ii), referencing a settlement agreement. Per the docket analysis of Case 6:21-cv-01153:
  • Pedersen's infringement claims dismissed WITH prejudice (all claims raised or raisable against Mailgun extinguished; cannot re-file).
  • Mailgun's counterclaims dismissed WITHOUT prejudice (preserved for potential re-assertion).
  • Each party to bear its own costs, expenses, and attorneys' fees; no prevailing party declared.
  • The court's recorded termination basis is "Case Dismissed."
    (Source: PatSnap litigation summary, "Pedersen v. Mailgun Technologies – US6965920B2 Patent Dismissed," citing PACER records for 6:21-cv-01153.)
• Timing: The exact dismissal date is not confirmed in my sources. The case was still listed as "Pending" in Oracle's IPR Mandatory Notices dated 2023-06-02, so dismissal occurred after that date and before the case record was closed. I note that a sibling case (6:21-cv-01155, J2 Global) had a joint stipulation of dismissal filed 2023-05-08, but I did not find an equivalent docket entry date for this case.
• No appeal of the district court case (dismissal was by stipulation, not an appealable merits ruling).

7. Parallel PTAB Proceedings — and Their Effect

The '920 patent was challenged in at least three IPRs, which materially affected (and ultimately determined) the patent's fate:

• IPR2023-00029 — Unified Patents, LLC v. Peter Henrik Pedersen (the lead proceeding):
  • Unified challenged claims 1 and 14–17 on obviousness over Funk + Law and Funk + Kamakura (instituted grounds).
  • The PTAB issued a Final Written Decision holding claims 1 and 14–17 unpatentable as obvious, locating the messenger-specific delivery-parameter limitation in Funk. (Sources: PTACTS Final Written Decision excerpts; Fed. Cir. opinion.)
  • Pedersen appealed to the Federal Circuit (No. 2024-2090).
  • 2026-03-26 — Federal Circuit AFFIRMED (nonprecedential; Lourie & Hughes, C.JJ., and Kleeh, C.D.J.). The court held the Board's obviousness findings were supported by substantial evidence, including Funk's disclosures and expert testimony on recipient-specified delivery preferences keyed to specific messengers. (Sources: Fed. Cir. opinion, 24-2090 (Mar. 26, 2026); Patterson Sheridan Fed. Cir. summary; Unified Patents insight; IP Law Daily/Vital Law.)
  • This affirmance invalidates the asserted claims of the patent-in-suit, a post-dismissal development that forecloses any future re-assertion of claims 1 and 14–17 against Mailgun or anyone else.
• IPR2023-00867 — Oracle Corp. v. Pedersen and IPR2023-00986 — Adobe Inc. v. Pedersen: parallel petitions on the same '920 patent (mandatory notices/petitions dated June 2023). The district court filings from this very case (the Markman briefs, the Claim Construction Order, and the June 14, 2022 Scheduling Order) were submitted as exhibits in these IPRs, showing the district case fed directly into the PTAB record. (Sources: Oracle Mandatory Notices, June 2, 2023; Adobe petition exhibits, June 1, 2023; Unified Patents exhibit list, Feb. 9, 2024.)
• Effect on the litigation: No stay pending IPR is documented in this case; the parties settled and dismissed before the PTAB decisions matured. The practical effect of the IPR chain was to render the asserted patent claims invalid after the case settled — meaning the settlement's "with prejudice" bar against Mailgun is now reinforced by the fact that the asserted claims themselves have been cancelled/held unpatentable.

---

Bottom Line / Present Posture

The case is closed. It was filed 2021-11-09, litigated through claim construction (Markman hearing and Order on 2022-10-19), and then settled and dismissed by joint stipulation under Rule 41(a)(1)(A)(ii) — Pedersen's claims with prejudice, Mailgun's counterclaims without prejudice, no fee-shifting. No trial or post-trial motions occurred. Separately, the asserted patent's claims 1 and 14–17 were found unpatentable in IPR2023-00029, affirmed by the Federal Circuit on 2026-03-26, so the '920 patent is no longer enforceable as to those claims.

Confidence notes: The complaint date, scheduling order, claim-construction filings/hearing/order, IPR numbers, and Federal Circuit affirmance are well-sourced (court filings exhibited in PTAB records; the Fed. Cir. opinion; secondary litigation-intelligence summaries). The exact answer/counterclaim filing date, the precise stipulation-of-dismissal filing date, and any discovery milestones could not be verified from the available search results and are flagged as unconfirmed rather than asserted.

I'll research the counsel of record for plaintiff Peter Henrik Pedersen in this case using multiple sources.

I have initial results. Let me dig deeper into the district court docket to verify the exact counsel of record and any local counsel appearances.

Let me verify with the actual docket filings and check for any additional counsel (local counsel, pro hac vice).

Based on my research across PACER-derived docket databases, PTAB filings, and firm sources, here is the counsel-of-record picture for plaintiff Peter Henrik Pedersen in Pedersen v. Mailgun Technologies, Inc., No. 6:21-cv-01153-ADA (W.D. Tex., Waco Div., Judge Alan D. Albright):

Plaintiff's Counsel of Record

1. William P. Ramey III

• Role: Lead district court counsel (signs pleadings as "Attorneys for Plaintiff Peter Pedersen"); managing partner of Ramey LLP
• Firm & Office: Ramey LLP, 5020 Montrose Blvd., Suite 800, Houston, Texas 77006
• Experience: High-volume patent plaintiff litigator before Judge Albright's W.D. Tex. docket; represents Pedersen's nationwide enforcement campaign over U.S. Patent No. 6,965,920 (including suits against Blackbaud, Constant Contact, Monday.com, Wix.com, Zendesk, Intuit, Salesforce, and others). PTAB registration No. 44,295; signed the October 12, 2022 Joint Claim Construction Statement in this case.

2. Kyril Vladimir Talanov

• Role: Plaintiff's counsel (Ramey LLP), listed alongside Ramey III in the litigation databases derived from the PACER docket for this case
• Firm & Office: Ramey LLP, Houston, Texas (same office)
• Experience: Member of Ramey LLP's Pedersen/’920-patent litigation team; identified as litigation counsel on the patent owner's courtesy-copy service list in parallel PTAB proceedings (IPR2023-00986, Adobe v. Pedersen), where he was listed with the Ramey LLP litigation email (ktalanov@rameyfirm.com).

Related counsel (PTAB context, not district-court docket)

• Jacob B. Henry (Ramey LLP, Houston) was designated lead counsel for Pedersen as patent owner in IPR2023-00867 (Oracle Corp. v. Pedersen) and IPR2023-00029 (Unified Patents v. Pedersen), with Ramey III as back-up counsel. Henry does not appear in the district-court signature blocks I verified for this case, so I would not list him as district-court counsel of record absent a docket confirmation.
• Donald Trey Mahoney (Ramey LLP) appears on the PTAB courtesy-copy email list for Pedersen's litigation team, but I found no district-court filing in this case signed by him, so his appearance status here is unverified.

Caveats

• Source basis: The primary docket-derived sources are (a) PatSnap's litigation database entry for 6:21-cv-01153 (which lists plaintiff counsel as Kyril Vladimir Talanov and William P. Ramey III, firm Ramey LLP) and (b) the filed Joint Claim Construction Statement (signed by William P. Ramey III, State Bar No. 24027643, as "Attorneys for Plaintiff Peter Pedersen"). I could not pull the original complaint's signature block or the full CM/ECF appearance list directly, so the complete universe of attorneys who formally entered appearances (e.g., any additional associates or separately designated local counsel) is not independently verified.
• Local counsel: No separate local counsel for the plaintiff was identified. Ramey LLP is a Texas firm (Houston), and its attorneys have appeared directly in numerous W.D. Tex. patent cases, so no distinct local-counsel designation was apparent from the filings reviewed.
• Case status discrepancy: The case metadata says "Active," but docket-derived analysis indicates the case was terminated via a joint stipulation of dismissal under Rule 41(a)(1)(A)(ii) referencing a settlement—Pedersen's claims dismissed with prejudice, Mailgun's counterclaims without prejudice, each side bearing its own fees. The dismissal does not affect the identification of counsel of record during the litigation.

Defendant's Counsel of Record — Pedersen v. Mailgun Technologies, Inc. (6:21-cv-01153-ADA)

Mailgun Technologies, Inc. was represented by Goodwin Procter LLP (national IP-litigation counsel) and Slayden Grubert Beard PLLC (Texas local counsel). The following five attorneys appear on the public record for Mailgun, per PatSnap's PACER-based docket analysis and a signed defense filing (Oct. 12, 2022) produced in the related PTAB record (Adobe Inc. v. Pedersen, IPR2023-00986, Ex. 1007/1008):

Sourcing notes & caveats

• Confirmed by signature block: Schuman, Daughtrey, and Adams are confirmed counsel of record by a signed Mailgun filing dated October 12, 2022 (W.D. Tex. case no. 6:21-cv-01153-ADA), hosted on the USPTO PTACTS portal in the Adobe IPR record (Dkt. 23-related exhibit; also reproduced on Docket Alarm). That filing identifies Schuman and Daughtrey as pro hac vice and Adams as the Texas-licensed signatory.
• Cheng and "Kline Moore": These names come from PatSnap's PACER-based party-and-counsel table. Cheng's identity is corroborated by Goodwin's attorney bio (patent litigation, complex technologies). "Kline Moore" is not corroborated by any independent source; I flag it explicitly rather than invent details.
• No in-house counsel of record for Mailgun appears in the available sources (Mailgun is a Sinch AB subsidiary, but no in-house appearance was found).
• Posture at dismissal: The case ended by Rule 41(a)(1)(A)(ii) joint stipulation referencing a settlement — Pedersen's claims dismissed with prejudice, Mailgun's counterclaims dismissed without prejudice, each side bearing its own fees — so all appearances above are historical; the docket closed without a merits ruling.

If you need the precise docket numbers for each attorney's notice of appearance (e.g., the pro hac vice motions/orders), those entries are not publicly indexed in the sources I could reach; a PACER lookup on 6:21-cv-01153-ADA (attorney appearances report) would confirm them directly.
