CommWorks Solutions, LLC v. AVM GmbH

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

Let me verify party details, counsel, IPR linkage, and the dismissal.

Case Overview & Background — CommWorks Solutions, LLC v. AVM GmbH, No. 2:25-cv-00026 (E.D. Tex.)

The parties. CommWorks Solutions, LLC is a Georgia limited liability company (principal place of business in Alpharetta, GA) and a classic non-practicing entity/patent-assertion vehicle: it does not make or sell products, and it monetizes a patent portfolio it acquired rather than developed. Its Rule 7.1 disclosure identifies Brainbox Innovations, LLC as its corporate parent (see the parallel CommWorks v. EarthLink docket, 2:25-cv-00716, Dkt. 2/3), and it is widely reported as an affiliate of Georgia-based monetization firm IPInvestments Group LLC. RPX, IPWatchdog, and Mondaq have traced CommWorks' patents to Intellectual Ventures LLC (IV)—one of several Georgia LLCs that received thousands of IV assets in late 2019/2020—and IPWatchdog reported allegations (in Altice USA's 2021 declaratory-judgment filings) that IV retained a security interest and a "backend" on licensing revenue, i.e., an economic-interest linkage to IV (https://ipwatchdog.com/2021/09/22/patent-filings-roundup-trio-actions-accuse-ip-investments-coordinated-campaign-intellectual-ventures-backend-judge-albright-cancels-one-141-wsou-asserted-patents-new-magnetar-entity-s/; https://www.mondaq.com/unitedstates/patent/[950472](/patent/950472)/ipinvestments-kicks-off-multiple-campaigns-asserting-patents-among-thousands-received-from-intellectual-ventures). AVM GmbH is the opposite kind of party: a privately held German networking-hardware manufacturer headquartered in Berlin, founded in 1986 and best known for its FRITZ!Box line of consumer DSL/fiber/cable routers, mesh repeaters, and WLAN adapters—the dominant consumer router brand in Germany. (Note: the docket is captioned "AVM Corp" on some aggregators, e.g., Unified Patents, while the complaint names AVM GmbH; the First Amended Complaint filed 2025-02-06 names AVM GmbH.)

The accused technology and the patents. The complaint targets AVM's Wi-Fi networking gear—FRITZ!Box routers, FRITZ!Repeater, and FRITZ!WLAN Stick products—specifically their implementation of two standardized Wi-Fi features: Wi-Fi Multimedia (WMM), the IEEE 802.11e-derived QoS/priority-traffic mechanism, and Wi-Fi Protected Setup (WPS), the push-button provisioning standard (see the first amended complaint analysis at https://ai-lab.exparte.com/case/dct/txed/2:25-cv-00026/doc/8). Two asserted patents are the focus of the case metadata and the prior summary: U.S. 7,027,465, "Method for Contention Free Traffic Detection" (issued Apr. 11, 2006), which claims extracting a bit pattern from a predetermined position/offset in a data frame and comparing it against a search pattern to classify the frame as priority traffic without parsing upper-layer protocols; and RE44,904, a reissue bearing the same title and directed to the same contention-free/priority-frame-detection functionality tied to WMM. In plain terms, both are MAC-layer QoS detection patents that CommWorks maps onto WMM's traffic-prioritization behavior. Important caveat: although the case metadata and prior summary list only the '465 and '904 patents, the original complaint (Dkt. 1) attached evidence-of-use exhibits for six patents—7,177,285; 7,463,596; 7,911,979; RE44,904; 7,027,465; and 6,891,807—covering WMM/QoS and WPS provisioning. The two-patent framing in the case metadata is therefore incomplete relative to the pleaded case; I have not found a public narrowing stipulation, so the reduction may simply reflect how the case was summarized.

Posture, venue, and why it matters. Filed January 12, 2025 (Dkt. 1 entered 1/13/2025) in the Marshall Division of the Eastern District of Texas before Judge Rodney Gilstrap—historically the nation's premier plaintiff-side patent venue—the case was amended (First Amended Complaint, 2025-02-06) and then dismissed without prejudice by Judge Gilstrap's order of June 19, 2025 (entered 6/20/2025), with the AO-120 termination notice emailed to the USPTO (Unified Patents docket: https://portal.unifiedpatents.com/litigation/Texas%20Eastern%20District%20Court/case/2:25-cv-00026). The roughly five-month life means there was no claim construction, no dispositive ruling, and no merits adjudication, and the public docket does not disclose the reason for dismissal—so any characterization of it as a settlement, license, or venue/service-driven withdrawal would be speculation. The case is notable for several reasons: (1) it is a mass-filing NPE campaign—CommWorks filed against DrayTek (2:25-cv-00024) the same week and has sued a long list of router/switch/chipset makers (Comcast, RCN, D-Link, Charter, Extreme Networks, CommScope/ARRIS, Hon Hai/Belkin/Linksys, Technicolor, NXP, STMicroelectronics, TI, u-blox, Microchip, EarthLink, Grandstream), seeking portfolio-wide licenses; (2) it asserts standardized, near-universal Wi-Fi functionality (WMM/QoS and WPS) against a foreign, largely non-U.S.-facing defendant, which raises obvious TC Heartland venue and service-of-process questions for a German company that sells the accused FRITZ!Box gear primarily in Europe—an issue that frequently drives early dismissal; and (3) it sits in the IPR/reexam shadow—Unified Patents has run an active campaign challenging the CommWorks portfolio through ex parte reexamination (Lexology, July 2022: https://www.lexology.com/library/detail.aspx?g=14c49056-81e4-4ee1-a4a7-1ec58aee6400), which is the kind of defensive-patent-fund pressure that often precedes quick NPE exit. What I could not verify: a specific IPR or ex parte reexamination challenging the '465 or RE44,904 patents, and the precise reason for the without-prejudice dismissal. Both should be treated as open questions rather than established facts.

I'll research this case across multiple sources, working through the docket, rulings, PTAB proceedings, and disposition.

Let me dig into the docket specifics and any PTAB proceedings on the asserted patents.

Key Legal Developments — CommWorks Solutions, LLC v. AVM GmbH, No. 2:25-cv-00026 (E.D. Tex.)

Research caveat up front: The public record for this case is thin. What is available consists of the PACER/RECAP docket entries surfaced through Unified Patents' litigation portal and CourtListener, plus AI-generated summaries of the complaint hosted by Ex Parte. I was able to verify the filing, amendment, and dismissal entries, but I could not retrieve the complete PACER docket for the window between the amended complaint (February 2025) and the dismissal (June 2025). Statements below about the absence of answers, motions, or Markman proceedings reflect what appears in the available record, not a certainty that nothing was filed. Negative findings on PTAB activity carry the same caveat. I have flagged each item accordingly.

1. Filing and initial pleadings

2025-01-12 (entered 01/13/2025) — Original Complaint. CommWorks Solutions, LLC (an Alpharetta, Georgia LLC) filed a six-patent infringement complaint against AVM GmbH, identified as a German corporation with its principal place of business at Alt-Moabit 95, 10559 Berlin, Germany. The complaint attached six "Evidence of Use" exhibits:

This matters for framing the case: the complaint asserted six patents across two Wi-Fi standard functionalities — WPS (the '285/'596/'979/'807 time-based provisioning family) and WMM/802.11e QoS (the '465 and '904 "contention-free traffic detection" pair). Your case metadata lists only 7,027,465 and RE44,904 as the patents at issue, which corresponds to the WMM half of the complaint and to Exhibit E specifically. The narrowing to two patents is consistent with the campaign-level framing in the summary you provided, but the operative pleading on the public record pleaded all six.

Venue and jurisdiction theory. Because AVM is a foreign (alien) defendant, the complaint pleaded venue under the alien-venue rule, 28 U.S.C. § 1391(c)(3), expressly citing In re HTC Corp., 889 F.3d 1349, 1357 (Fed. Cir. 2018), for the proposition that TC Heartland does not disturb the rule that a non-resident alien may be sued in any district. Subject-matter jurisdiction was pleaded under 28 U.S.C. §§ 1331, 1338(a); personal jurisdiction on a specific-and-general-jurisdiction theory plus the Texas long-arm statute. This is a notable strategic feature: CommWorks could not rely on AVM's U.S. presence, so it rested venue on AVM's status as a foreign entity.

Accused products. AVM SoCs and the FRITZ!Box, FRITZ!Repeater, and FRITZ!WLAN Stick lines, including the FRITZ!Box 7390 (WMM mapping for the '465/'904 pair) and FRITZ!Box 5590 Fiber / 4060 AX / 6890 LTE for the WPS family. The WMM theory is that operation of the IEEE 802.11e QoS feature practices the claimed "extract a bit pattern from a predetermined position in a frame and compare it with a search pattern" method. (Technology mapping details are drawn from an AI-generated complaint analysis; treat the specific paragraph cites as approximate.)

Willfulness / notice allegation. The complaint alleged AVM had knowledge of the '465 patent upon receiving a Notice Letter in April 2023, and further alleged AVM maintained a policy of instructing employees not to review others' patents, rendering it "willfully blind." (An AI-generated analysis of the same complaint references a "February 2, 2022 notice letter" for willfulness purposes; the two dates conflict. The complaint text I could retrieve attributes knowledge of the '465 patent to the April 2023 letter. I could not reconcile these, and the exact notice date should be verified against the pleading.)

2025-02-06 (entered 02/07/2025) — First Amended Complaint. CommWorks filed a First Amended Complaint for patent infringement against AVM GmbH. The docket entry does not on its face disclose which patents were added or dropped; given the June 19 dismissal, this amendment was not tested by any motion practice visible in the record.

Answer / counterclaims. I found no answer, no Rule 12 motion, and no counterclaim in the docket materials available to me. For a foreign defendant, the absence of an answer is plausibly explained by the service timeline: AVM would have required service abroad under the Hague Service Convention, which routinely consumes months, and the case was dismissed roughly four months after the amended complaint. I cannot confirm whether service was ever perfected, whether an extension of time was granted, or whether AVM appeared at all. This is the single largest evidentiary gap in the timeline, and it should be verified on PACER before being characterized definitively.

---

2. Pre-trial motions of substance

None identified. Based on the available docket listing, the case produced no motion to dismiss, no motion to transfer venue, no motion to stay pending IPR, and no dispositive or summary-judgment motion. The visible docket jumps from the February 7, 2025 amended complaint to the June 19, 2025 dismissal order with nothing in between.

Two implications worth noting for a case-assessment memo:

• The absence of any venue-transfer motion is unsurprising given AVM's alien status (§ 1391(c)(3) forecloses the ordinary TC Heartland-based transfer argument), but a German defendant might still have sought dismissal for insufficient service or for lack of personal jurisdiction — none appears.
• The absence of a stay motion is consistent with the absence of any parallel PTAB proceeding (see § 6 below).

---

3. Claim construction (Markman)

The case never reached claim construction. It terminated approximately five months after filing and roughly four months after the amended complaint. No Markman order, no O2 Micro / Phillips briefing, and no claim-construction hearing appear anywhere in the available record. Any claim-scope questions about the "predetermined position"/"search pattern" limitations of the '465 and '904 patents and the "time interval" limitations of the provisioning family remain unadjudicated.

---

4. Discovery milestones

No discovery milestones of record. With termination before the E.D. Tex. scheduling-order machinery could mature — Gilstrap's docket ordinarily sets a scheduling order within a few months of appearance, with an IPR/venue/Markman sequence — the case almost certainly never reached substantive merits discovery. The only step of arguable strategic significance visible in the record is the First Amended Complaint, which functions as a pre-discovery self-correction and sometimes signals a plaintiff that has obtained additional product-teardown or claim-mapping evidence against a target that has not yet appeared.

---

5. Trial, verdict, and post-trial motions

None. There was no trial, no verdict, and therefore no JMOL, new-trial, or fee motion under 35 U.S.C. § 285 or Fed. R. Civ. P. 54(d).

---

6. Parallel PTAB proceedings

I found no IPR, PGR, or CBM proceeding on U.S. Patent 7,027,465 or RE44,904. This is a negative finding and is heavily obscured by search noise: there are several other, unrelated patents styled "'904" that dominate PTAB results — e.g., Orckit's 6,680,904 (IPR2023-00714, Cisco v. Orckit) and an ABT 5G patent also numbered as a '904 patent, both of which generate large document sets. Neither concerns the CommWorks reissue.

Two contextual points that bear on the PTAB question:

• The '465/'904 family appears to have been near or past the end of its life. The '465 patent issued April 11, 2006 from an application filed June 11, 2002. A twenty-year term from that 2002 filing date would put expiration in mid-2022 absent significant patent-term adjustment. Related CommWorks pleadings in the companion cases describe indirect-infringement theories running "from March of 2021 until its expiry," which is the language a patentee uses when the asserted right has lapsed. If the asserted claims had already expired (or were about to), (a) prospective relief was off the table and the case was a pure past-damages play, and (b) third-party IPR petitioners — who generally petition only to clear live patent rights — would have had little incentive to file. The expiration status and any PTA are worth confirming against Patent Center; I could not verify them directly.
• CommWorks is a serial, campaign-style filer. The same patents and exhibits recur across suits against Axon Networks (C.D. Cal. 8:24-cv-02250), STMicroelectronics (W.D. Tex. 7:25-cv-00363, voluntarily dismissed Nov. 2025), EarthLink (E.D. Tex. 2:25-cv-00716, voluntarily dismissed Oct. 2025), SIA Mikrotikls (E.D. Tex. 2:25-cv-00252), u-blox America (E.D. Va. 2:25-cv-00842), and others. CommWorks' Rule 7.1 disclosure in the EarthLink matter identifies its corporate parent as Brainbox Innovations, LLC. Campaign-level assertion of the same small patent set against many targets — with a pattern of short-lived suits terminated by voluntary dismissal — is a fact pattern that PTAB petitioners and § 285 fee-motivated defendants look at closely.

Effect on this litigation: none. There was no PTAB proceeding to trigger a stay or to create estoppel or collateral-effects pressure on the district court case.

---

7. Final disposition and present posture

2025-06-19 — Order Dismissing Case Without Prejudice. Signed by District Judge Rodney Gilstrap (entered 06/20/2025). The docket entry reads: "ORDER DISMISSING CASE WITHOUT PREJUDICE. Signed by District Judge Rodney Gilstrap on 06/19/2025."

2025-06-19 — AO 120 Notice. Notice of Filing of Patent/Trademark Form (AO 120) at Termination of the case, emailed to the Director of the USPTO.

The case is closed. The dismissal was without prejudice, which leaves CommWorks free to refile against AVM on the same patents. The order does not, on its face, indicate whether it followed a notice of voluntary dismissal under Rule 41(a)(1) or a joint stipulation, and no settlement amount, license, or fee award appears in the record. Whether this was a litigation-strategy abandonment (e.g., service or personal-jurisdiction problems on a German defendant, or an expired patent), a confidential settlement/license, or a refiling decision cannot be determined from the public docket, and I would not characterize it without pulling the underlying motion or notice.

Appeal: none. The case resolved at the district court by dismissal without prejudice, and no Federal Circuit docket was identified.

Consolidated chronology

---

Analytical takeaways

1. This was an early-stage, unresolved case, not a merits ruling. Nothing here creates claim-construction, validity, or infringement law. Its value is as campaign intelligence, not precedent.
2. The two-patent framing in your metadata reflects the WMM half of a six-patent complaint. If you are assessing the '465/'904 pair specifically, note that the operative pleading also swept in the four-patent WPS/time-based-provisioning family, and that the entire family has been asserted across a national campaign out of a single parent entity (Brainbox Innovations).
3. Defendant characteristics drove the procedural posture. AVM is a German alien defendant; CommWorks pleaded venue under § 1391(c)(3)/In re HTC rather than on U.S. residence, and the foreign-service timeline plausibly explains why the case died before any merits motion.
4. Possible expired-patent dynamics. The '465/'904 pair issued from 2002-era filings, and companion pleadings reference infringement running "until its expiry." If the asserted claims had lapsed, the suit was a past-damages claim only and there was little third-party incentive to file IPRs — which is consistent with the absence of PTAB activity.
5. The without-prejudice dismissal is not res judicata and does not resolve anything. Treat the patents as unresolved and potentially re-assertable.

Recommended verification steps before relying on this timeline: (a) pull the full PACER docket for 2:25-cv-00026 to confirm the absence of an answer, motions, and any service/extensions; (b) pull the Rule 41 dismissal filing or order to determine whether the dismissal was voluntary, stipulated, or settled; (c) confirm the '465 and '904 expiration dates and any patent-term adjustment on USPTO Patent Center; and (d) run a Patent Trial and Appeal Board proceeding search restricted to the two patent numbers rather than the "'904" string.

I'll research the docket and counsel records for this case.

Let me pin down the specific docket appearances and the firm affiliations.

Bottom line

For CommWorks Solutions, LLC v. AVM GmbH, No. 2:25-cv-00026 (E.D. Tex.), the only attorney whose appearance is affirmatively documented on this docket is C. Matthew ("Carey") Rozier of Rozier Hardt McDonough PLLC, who filed both the original Complaint (Doc. 1, entered 01/13/2025) and the First Amended Complaint (Doc. 8, entered 02/07/2025). The case was a short-lived, one-defendant German-venue case that was dismissed without prejudice on 06/19/2025 before any substantive motion practice, so the plaintiff-side roster on this specific docket is thin.

CommWorks is a serial filer in the E.D. Tex./W.D. Tex. WPS/WMM campaign using a small, stable in-house-outside team from Rozier Hardt McDonough ("RHD"). That broader roster is well documented in the companion CommWorks complaints filed the same weeks — but I could not verify that each of those attorneys separately entered an appearance in 2:25-cv-00026 itself.

---

Confirmed on the 2:25-cv-00026 docket

Note on the pleadings: the CM/ECF "filing attorney" tag is (Rozier, Carey), and the complaint's Marshall Division caption identifies CommWorks as a Georgia LLC with its registered office in Alpharetta, GA — consistent with the RHD pattern of signing complaints via the Atlanta address (659 Auburn Avenue NE, Unit 254, Atlanta, GA 30312).

No defendant-side counsel inquiry was made here (the question is limited to plaintiff), and no pro hac vice orders, no local-counsel designation, and no default/joint-stipulation dismissal papers were located in the public record for this docket. Those may exist under seal or simply not have been captured by the aggregators.

---

The broader CommWorks plaintiff team at Rozier Hardt McDonough (verified in parallel/companion filings; appearance in 00026 unconfirmed)

CommWorks filed this case in the same wave as several other WPS/WMM suits, and the same small team appears across them. These are the attorneys I can source as CommWorks plaintiff-side counsel; treat the "role" column as the function they perform across the campaign rather than a docket-verified designation in 00026.

Also worth knowing on the IPR side: Kristin M. Whidby (USPTO Reg. No. 71,026, Rozier Hardt McDonough, 1500 K Street NW, 2nd Floor, Washington, D.C.) appears as back-up counsel on RHD's PTAB filings and is the natural #2 on the firm's patent-side team.

---

Caveats and open items

• No separate "local counsel" appears in the CommWorks E.D. Tex. filings I could retrieve. Hardt's Texas bar membership and Austin office appear to fill that function. I found no E.D. Tex. attorney outside RHD appearing for CommWorks in this campaign; if one exists, it is not in the public filings I located.
• Whether Matuszewski, McDonough, Hardt, or any other RHD attorney actually entered an appearance in 2:25-cv-00026 is unverified. The 00026 docket as reported by aggregators shows only the two pleadings filed by Rozier plus the dismissal order and AO 120 notice; appearance notices (Docs. 2–7, etc.) were not captured in those feeds. The case closed ~5 months after filing, which is consistent with a slim appearance record.
• Possible identity confusion — flagged, not resolved: Snell & Wilmer publishes a bio for a "C. Matthew Rozier" in its Denver/Washington, D.C. offices (contact mrozier@swlaw.com) with an employment history at Sterne Kessler, Fish & Richardson, and Hogan Lovells. That history does not match the Rozier Hardt McDonough attorney's trajectory (Williams Simons & Landis → RHD), so these may be two different attorneys with very similar names, or the Snell bio may be stale/mismatched. I would not attribute Snell & Wilmer representation to CommWorks without confirming. Source: Snell & Wilmer bio PDF.
• Dismissal rationale is not documented in the sources retrieved. The 06/19/2025 order dismissing without prejudice (signed by Judge Gilstrap, entered 06/20/2025) is in the record; whether it followed a joint stipulation, a settlement, or a venue/service issue with the German defendant AVM GmbH is not established by the material I could reach. The docket caption also alternates between "AVM GmbH" and "AVM Corp," which is a docketing artifact rather than a second defendant.
• Sourcing method: No PACER account access was used; the docket facts above come from the Unified Patents litigation portal, Justia Dockets, CourtListener/RECAP, and the filed complaint PDFs, cross-checked against the RHD firm's signature blocks in CommWorks complaints in other districts. Recommend a direct PACER pull of the 2:25-cv-00026 docket sheet to confirm the complete appearance list and any pro hac vice orders before relying on this roster in a filing.
