Untitled case

This case, USITC Investigation No. 337-TA-1489, centers on allegations of patent infringement concerning "certain laptops, routers and gateways, and components thereof." The Complainant, AX Wireless, LLC, based in Austin, Texas, is identified as a Non-Practicing Entity (NPE) and an entity of IdeaHub. The Respondents initially included ASUSTeK Computer Inc. and ASUS Computer International, Inc. (Taiwan and California, respectively), TP-Link Systems Inc. (California), D-Link Corporation and D-Link Systems, Inc. (Taiwan and California, respectively), and Ubiquiti Inc. (New York). However, the investigation was recently terminated as to D-Link Corporation and D-Link Systems, Inc. based on consent orders, a decision the Commission opted not to review as of May 19, 2026.

The litigation asserts infringement of several U.S. Patents, including 11,777,776, 10,079,707, 10,917,272, 11,646,927, and 12,063,134. Specifically, U.S. Patent 11,777,776, titled "Partitioning of wiring for capacitance extraction without loss in accuracy," broadly describes methods for analyzing integrated circuit designs by partitioning an overall shape into sub-shapes, performing capacitance extraction for each sub-shape (including adjacent portions), and then combining these individual capacitance amounts to determine a total capacitance for the entire design.

The case is being heard before the U.S. International Trade Commission (USITC), which instituted the investigation on March 6, 2026, following a complaint filed by AX Wireless, LLC on February 2, 2026. The procedural posture involves an Administrative Law Judge (ALJ) being assigned to conduct an evidentiary hearing and issue an initial determination, which is then subject to review by the full Commission for a final decision. The USITC is a critical venue for patent holders due to its in rem jurisdiction over imported goods, which can lead to powerful exclusion orders preventing infringing products from entering the United States. Furthermore, ITC investigations are known for their expedited timelines, typically aiming for completion within 16 months, offering a faster resolution compared to traditional district court litigation.

This case is notable due to the Complainant, AX Wireless, LLC, being an NPE, a common characteristic of Section 337 investigations. The assertion of these patents against major electronics manufacturers in the laptop, router, and gateway markets highlights the ongoing trend of NPEs leveraging the ITC's unique remedial powers. A significant development affecting this case is a parallel ex parte reexamination proceeding initiated by Unified Patents against U.S. Patent 11,777,776. On April 24, 2026, the Central Reexamination Unit (CRU) granted Unified Patents' request, finding substantial new questions of patentability on all challenged claims of the patent, which could potentially impact the outcome of the ITC investigation.

This outlines the key legal developments and outcomes in the USITC Investigation No. 337-TA-1489, along with parallel PTAB proceedings.

Filing & Initial Pleadings

• Complaint Filing: AX Wireless, LLC filed the initial complaint with the U.S. International Trade Commission (USITC) on February 2, 2026. Supplements to the complaint were filed on February 10, 2026. The complaint alleges violations of Section 337 of the Tariff Act of 1930 due to the importation and sale of certain laptops, routers, gateways, and components infringing U.S. Patent Nos. 10,079,707, 10,917,272, 11,646,927, 11,777,776, and 12,063,134.
• Institution of Investigation: The USITC voted to institute the investigation on March 4, 2026, and a notice of institution was published in the Federal Register on March 6, 2026.
• Parallel District Court Filings: AX Wireless, LLC also filed parallel patent infringement lawsuits against ASUSTeK Computer Inc., ASUS Computer International, Inc. in the Eastern District of Texas (2:26-cv-00086) on February 2, 2026, and against TP-Link Systems Inc. in the Central District of California (8:26-cv-00251) on February 2, 2026. The case against TP-Link Systems Inc. was subsequently stayed pending resolution of the ITC proceedings.
• Respondents' Answers: Respondents were required to submit responses to the complaint and notice of investigation within 20 days of service.

Pre-Trial Motions of Substance

• Motion to Terminate (D-Link): On April 3, 2026, D-Link Corporation and D-Link Systems, Inc. filed a motion to terminate their involvement in the investigation based on a consent order stipulation and proposed consent orders. Complainant AX Wireless, LLC did not oppose the motion, and the Office of Unfair Import Investigations (OUII) supported it.
• ALJ Initial Determination (D-Link Termination): On April 30, 2026, the Administrative Law Judge (ALJ) issued an Initial Determination (Order No. 13) granting D-Link's motion to terminate.
• Commission Determination Not to Review (D-Link Termination): On May 19, 2026, the USITC determined not to review the ALJ's Initial Determination, thereby officially terminating the investigation as to D-Link Corporation and D-Link Systems, Inc. based on the consent orders.

Claim Construction (Markman) Outcomes

• No information on specific claim construction (Markman) outcomes is publicly available at this early stage of the ITC investigation. Typically, a Markman hearing would occur later in the expedited ITC timeline, after initial discovery.

Discovery Milestones with Strategic Significance

• Protective Order: The ALJ issues a protective order governing discovery and the handling of "confidential business information" (CBI), which includes provisions for "attorneys' eyes only" access.

Trial Events, Verdict, and Post-Trial Motions

• The case is still in its early stages before the USITC, so no trial events, verdicts, or post-trial motions have occurred yet. The ALJ will schedule and hold an evidentiary hearing and issue an initial determination on violation.

Settlement, Dismissal, Judgment, or Appeal

• Partial Dismissal via Consent Order: The investigation has been terminated as to D-Link Corporation and D-Link Systems, Inc. due to consent orders, effective May 19, 2026. The investigation remains active against ASUSTeK Computer Inc., ASUS Computer International, Inc., TP-Link Systems Inc., and Ubiquiti Inc.

Parallel PTAB IPR/PGR Proceedings

• Ex Parte Reexamination of U.S. Patent 11,777,776: Unified Patents initiated an ex parte reexamination proceeding against U.S. Patent 11,777,776, owned by AX Wireless, LLC.
• Substantial New Question of Patentability Found: On April 24, 2026, the Central Reexamination Unit (CRU) granted Unified Patents' request, finding substantial new questions of patentability on all challenged claims of U.S. Patent 11,777,776. This development could significantly impact the ITC investigation as it raises questions about the validity of a key asserted patent.

Counsel of Record for the Complainant — AX Wireless, LLC

Sourcing caveat (read first). The ITC does not maintain attorney "appearances" the way district courts do; complainant's counsel of record in a § 337 investigation is established by (a) the counsel block on the complaint and (b) the Rule 201.16(c)/210.4 service list in each filing. I was not able to pull the EDIS docket entries for 337-TA-1489 itself through open-web search (EDIS requires interactive access and its documents are not indexed by search engines). The identification below is therefore grounded in three correlated sources, which I flag by confidence:

1. High confidence — the same firm and near-identical attorney team appear in AX Wireless's co-filed district court complaints (filed February 2, 2026, the same day as the ITC complaint), in AX Wireless's prior ITC investigation 337-TA-1445 (Certain Video Game Consoles, Routers and Gateways), and in AX Wireless's PTAB filings for the same patent family.
2. Moderate confidence — individual attorney roles (lead vs. backup vs. local) in 1489 specifically.
3. Not verified — any 1489-specific pro hac vice or notice-of-appearance filing, and the firm of local counsel Alex H. Chan.

Principal counsel: Devlin Law Firm LLC (Wilmington, Delaware)

AX Wireless is a repeat player represented by Devlin Law Firm LLC, 1526 Gilpin Avenue, Wilmington, DE 19806 (with a Texas office; historically 1411 North Trail Drive, Carrollton, TX). The firm's ITC signature block for AX Wireless in 337-TA-1445 reads: "/s/ Christopher May, Timothy Devlin, Christopher May, Lowell D. Jacobson, Joel Glazer, Srikant Cheruvu, Andrew Sherman, Tracey Starck, Leland Marcus, Hayden Corrales — DEVLIN LAW FIRM LLC … Attorneys for Complainant AX Wireless, LLC." (Joint submission in Inv. No. 337-TA-1445, Ex. 2013 filing available via USPTO PTAB, IPR2025-00960.)

Local / other counsel

• Alex H. Chan — designated local counsel for AX Wireless in the C.D. Cal. D-Link action (per the order granting Lowell Jacobson's pro hac vice application, AX Wireless v. D-Link, 8:26-cv-00252). Firm affiliation not confirmed by the sources I could access; I decline to guess.
• In-house contact: the 337-TA-1445 complaint lists AX Wireless at 2025 Guadalupe Street, Suite 260, Austin, TX 78705, with contact "jgisone@axwireless.net." The name suggests an in-house contact, but I found no confirmation of title or scope, and no evidence of an in-house attorney appearing of record in 1489.

Party on the Commission's side (not complainant's counsel)

• Pathenia M. Proctor, Office of Unfair Import Investigations (OUII), USITC — the investigating attorney named in the Federal Register notice for 1489 (91 FR 11086, Mar. 6, 2026). OUII is a full party but does not represent AX Wireless.

Flags: contradictions and newer developments vs. the prior sections

1. Patent title error in the existing overview. The prior section describes the '776 patent as "Partitioning of wiring for capacitance extraction without loss in accuracy." That is incorrect for this family. Per AX Wireless's own complaint allegations as reported in the Ubiquiti action, U.S. Patent No. 11,777,776 is titled "Header repetition in packet-based OFDM systems" (issued Oct. 3, 2023) and claims a receiver apparatus supporting basic and extended packet formats — consistent with the 802.11ax/Wi-Fi 6 accused products. The capacitance-extraction title should be corrected.
2. TP-Link is no longer a respondent. The prior sections treat TP-Link Systems Inc. as active. According to USITC notice 337_1489_notice07222026 (91 FR, July 2026), the ALJ granted AX Wireless's unopposed motion to terminate as to TP-Link based on a settlement agreement (Order No. 17, June 25, 2026), and the Commission did not review it. Only ASUSTeK/ASUS and Ubiquiti remain as respondents.
3. Target date. Order No. 9 (Mar. 26, 2026) set a 21-month target date of December 6, 2027, with any final ID by August 6, 2027; the Commission declined review on April 15, 2026.
4. Complaint amended. Order No. 14 (May 19, 2026), unreviewed (91 FR 36615, June 17, 2026), added dependent claims 7, 9, 10, and 20 of the '272 patent to the investigation.

Bottom line: AX Wireless's counsel of record is Devlin Law Firm LLC (Wilmington, DE), with Timothy Devlin and Christopher May as the ITC-facing leads and Jason M. Shapiro as the designated lead for the parallel PTAB proceedings. If you need the exact 1489 attorney list as filed, the authoritative source is the EDIS docket (Inv. No. 337-TA-1489) — specifically the complaint's counsel block and the Rule 201.16(c) service lists in Complainant's filings — which I could not retrieve here.

I'll research respondents' counsel across the ITC docket and the parallel district court actions.

Respondents' counsel in Inv. No. 337-TA-1489 ("Certain Laptops, Routers and Gateways, and Components Thereof")

Threshold correction to the task framing. This is a § 337 investigation, not a district court case, so the operative concept is "respondents," not "defendants," and there is no single "docket sheet" for counsel. Also — consistent with Flag #2 in the prior section — the respondent set has shrunk. Per the Commission's July 2026 notice (337_1489_notice07222026sgl.pdf) and the June 17, 2026 Federal Register notice (91 FR 36615), the only remaining respondents are ASUSTeK Computer Inc. / ASUS Computer International, Inc. and Ubiquiti Inc. D-Link (Order No. 13, May 19, 2026) and TP-Link (Order No. 17, June 25, 2026, settlement) are out.

Sourcing caveat, stated up front. I was able to verify counsel for exactly one respondent group. EDIS (the ITC's Electronic Document Information System) is not indexed by search engines, and the Federal Register notices in this investigation list only the OUII investigating attorney (Houda Morad) — never respondents' counsel. Unlike a district court, the ITC does not publish a party-by-party counsel roster in the Federal Register. Everything below is therefore a mix of (a) verified district-court and PTAB appearances in the co-filed cases, and (b) explicit non-findings. I have not invented any attorney for any respondent I could not verify.

Verified: Ubiquiti Inc.

Confidence: high that Fish & Richardson (Conrad) is Ubiquiti's litigation counsel of record in the parallel N.D. Ill. case; moderate that the same team is Ubiquiti's ITC counsel in 1489. ITC respondents frequently use separate ITC-focused counsel, and ITC practice requires a Rule 210.13(a)/201.16(c) service designation that is not in the public record I could reach.

Not verified — ASUSTeK Computer Inc. / ASUS Computer International, Inc.

I found no verifiable attorney appearance for ASUS in either 337-TA-1489 or the co-filed E.D. Tex. action, AX Wireless, LLC v. ASUSTeK Computer Inc., No. 2:26-cv-00086 (E.D. Tex., filed Feb. 2, 2026). The aggregator pages for that docket (Ex Parte, RPX, Stanford NPE) show the complaint and the five asserted patents ('707, '272, '927, '776, '134) but no appearance entries in the records I could access; one secondary source (ANZONE, Feb. 2026) likewise states that as of its writing "no public response yet from the four defendants." I decline to guess at ASUS's ITC or district-court counsel.

One negative data point worth flagging: AX Wireless's prior ITC case, 337-TA-1445, does not help here. Its respondents were Sony Interactive Entertainment and Vantiva — not ASUS. So there is no ASUS-side ITC team from 1445 to carry forward by inference.

Not verified — terminated respondents (for completeness only)

• TP-Link Systems Inc. — terminated June 25, 2026 on settlement (Order No. 17), so any counsel of record is now moot for the investigation. Its C.D. Cal. case, No. 8:26-cv-00251, is the surviving venue of interest. Counsel not verified.
• D-Link Corporation / D-Link Systems, Inc. — terminated May 19, 2026 by consent order (Order No. 13). In the co-filed C.D. Cal. action, No. 8:26-cv-00252, the docket reflects AX Wireless's own pro hac vice motion for Lowell D. Jacobson with Alex H. Chan as local counsel (Dkt. 12–13), but I could not verify D-Link's defense counsel.

Cross-reference (not repeated here)

The prior section already identifies Pathenia M. Proctor (OUII) as the Commission-side investigating attorney from 91 FR 11086 (Mar. 6, 2026). OUII is a party but not respondents' counsel; I note it only so the reader doesn't mistake OUII's participation for defense representation.

Where the authoritative answer actually lives

If you need the filed list, these are the specific EDIS artifacts for 337-TA-1489 that carry counsel names, in order of usefulness:

1. Respondents' verified responses to the complaint and NOI (due ~20 days post-service under 19 C.F.R. § 210.13) — the signature block names lead and backup counsel.
2. Notice of Appearance / Designation of Lead Counsel filings by each respondent (the analogue of the Devlin filing in 1445, EDIS doc. 847141, which is how we know AX Wireless's own lead is Christopher May).
3. The Joint Claim Construction Chart and Joint Stipulation — these list every party's full counsel block.
4. "Agreement to Be Bound by the Protective Order" filings by individual attorneys — these generate a name-by-name list.
5. Rule 201.16(c)/210.4 service lists on any respondent filing; and the transcript caption from the Markman/hearing, which the ALJ requires to list all counsel.

Flags

1. A stale secondary identifier is circulating. RPX's Feb. 7, 2026 write-up refers to the ITC complaint as "337-TA-3882." That is the pre-institution complaint docket number, not the investigation number; the investigation is 337-TA-1489 (instituted Mar. 4, 2026; 91 FR 11086, Mar. 6, 2026). Cite 1489.
2. Independent corroboration of prior Flag #1. The Unified Patents write-up (Mar. 6, 2026) confirms the '272 and '776 patents "generally relate to header field configurations (e.g., header repetition) in Orthogonal Frequency Division Multiplexing (OFDM) communication systems," and the E.D. Tex. complaint analysis confirms the '776 title as "Header repetition in packet-based OFDM systems" (issued Oct. 3, 2023; claims 1–6 asserted against ASUS). The "capacitance extraction" title in the original case overview remains wrong and should be corrected.
3. One gap I cannot close from open sources: whether ASUS and Ubiquiti are using ITC-specialist counsel distinct from their district-court teams. Given that both district cases are now stayed under § 1659 pending 1489, the ITC team is the operative one, and it is not publicly identifiable without EDIS access.

Bottom line: The only respondent-side counsel I can verify is David Brandon Conrad of Fish & Richardson P.C. (Dallas), with Rishi Gupta (Fish, Minneapolis) on the PTAB side, for Ubiquiti Inc. — established from his March 9, 2026 appearance and § 1659 stay motion in AX Wireless v. Ubiquiti, N.D. Ill. No. 1:26-cv-01174 (Dkts. 10–12). ASUS's counsel is unverified, and I have found no public source naming it in either the ITC investigation or E.D. Tex. 2:26-cv-00086.
