Vixel Corporation v. Brocade Communications Systems, Inc.

I'll research this case to ground the overview in verifiable sources.

Let me dig into the settlement, the Emulex acquisition, and the parallel QLogic case.

Case Overview & Background

The parties — two operating companies, not an NPE assertion. Vixel Corporation was a Bothell, Washington storage-networking hardware maker founded in 1991 as an optical transceiver manufacturer, which later built Fibre Channel SAN fabric switches and, after a 2002 restructuring, refocused on embedded Fibre Channel switch ASICs sold under the InSpeed brand to OEMs including HP, NetApp, Fujitsu, NEC, Apple, and Xyratex (Network Computing; StorageNewsletter). It was never profitable and carried roughly $141 million in accumulated losses when Emulex Corp. of Costa Mesa, California agreed to acquire it for about $310 million in cash ($10/share, announced October 8, 2003, closed November 2003), taking over the litigation (LA Times; GlobeNewswire). Defendant Brocade Communications Systems was the dominant Fibre Channel fabric-switch vendor, based in San Jose, selling the SilkWorm switch family (Network Computing). The commercial dispute was thus a direct competitor-on-competitor fight in the SAN switch market, though by 2003 Vixel had largely exited fabric switching — giving the assertion a monetization flavor after Emulex acquired the portfolio.

Accused technology and asserted patents. Vixel alleged that Brocade's manufacture and sale of SilkWorm switches incorporating the QuickLoop and Fabric Assist features infringed three patents (Network Computing; Silicon.de). All three share a February 18, 1997 priority date and list Vixel CTO Stuart Berman as inventor, and they are family members directed to attaching arbitrated-loop ("private loop") devices to a switched fabric: (1) U.S. 6,118,776, "Methods and Apparatus for Fibre Channel Interconnection of Private Loop Devices" (granted 2000) — interconnecting private loop devices through a fabric; (2) U.S. 6,185,203, "Fibre Channel Switching Fabric" (granted 2001) — the switch-fabric architecture that carries that loop traffic; and (3) U.S. 6,470,007, "Interconnection System for Fibre Channel Arbitrated Loop Including Private Loop Devices" (granted 2002) — the system-level counterpart covering loop-and-fabric interconnection (Network Computing; Google Patents). The '776 patent was the portfolio's lead asset: Vixel asserted it (and, per one report, all three patents) against QLogic in the District of Delaware in February/March 2003 over QLogic SANbox switches (Network Computing; OCBJ).

Procedural posture and why it matters. Vixel filed in the U.S. District Court for the Northern District of California on May 23, 2003 — the Northern District being the natural home court for San Jose–based Brocade but, as commentators noted at the time (Vixel being a Washington company suing QLogic in Delaware), an arguably unusual forum choice for a plaintiff; attorney David Garrod of Patterson Belknap was quoted calling the split filing strategy "a bit strange" and observing that filing in N.D. Cal. carried disadvantages for plaintiffs (Network Computing). I could not verify the assigned judge, division, or civil docket number from public sources, so I do not state them. Brocade answered and asserted counterclaims (the resolution references dismissal of "claims and counterclaims against each other"), and on September 28–30, 2004, Emulex and Brocade announced an expanded SMB/SAN partnership coupled with a three-year litigation standstill, dismissing the Vixel action without prejudice; both companies filed 8-Ks on the standstill (HPCwire; InternetNews; Brocade 10-Q excerpt). The case is notable on three counts: it was part of a downturn-era wave of patent assertions in Fibre Channel switching, characterized by one attorney as "not at all uncommon when sales slow"; it shows a patent portfolio converted into both royalty revenue and deal leverage — Emulex's June 2004 settlement of the parallel QLogic disputes produced a license under which QLogic paid royalties and acknowledged the validity of the three patents, while Brocade bought peace by becoming a partner; and it is an early example of a fixed-term litigation standstill used as a commercial deal term rather than a conventional license. No PTAB/IPR linkage exists or was found — the IPR regime postdates this suit and the patents (1997 priority, so nominally expiring around 2017) were never subject to any identified AIA proceeding; that negative finding is based on search results rather than an exhaustive PTAB docket check, so treat it as unverified.

I'll research this case across dockets, court opinions, and news sources.

I hit the tool-call ceiling mid-research, so the below reflects what I was able to source directly. I've flagged clearly where the record is thin rather than filling gaps.

Vixel Corp. v. Brocade Communications Systems, Inc. (N.D. Cal., filed 2003‑05‑23)

1. Filing and initial pleadings

2003‑05‑23 — Complaint filed. Vixel filed in the Northern District of California asserting three Fibre Channel patents:

All three trace to applications filed by Vixel CTO Stuart Berman in 1997 (common priority date 1997‑02‑18 for the '776/'203 family). The accused products were Brocade's SilkWorm switch line, specifically the QuickLoop and Fabric Assist features — i.e., Vixel's private‑loop interconnect patents aimed squarely at Brocade's loop‑support firmware.

Sources: Network Computing/Byte and Switch, "Vixel Slings Suit at Brocade" (2003‑05‑28); Brocade SEC Form 10‑Q ("On May 23, 2003, a suit captioned Vixel Corporation v. Brocade Communications Systems…"), indexed at getfilings.com (accession 0000891618‑04‑000679).

Answer / counterclaims. I could not retrieve docket entries for Brocade's answer or counterclaims. That Brocade asserted counterclaims is confirmed only indirectly: the September 2004 standstill announcement states the parties "dismissed without prejudice claims and counterclaims against each other" in this case (HPCwire/Emulex–Brocade press release, 2004‑10‑01). So counterclaims existed by the time of dismissal, but I have no verified filing date, count list, or grounds (invalidity/non‑infringement/inequitable conduct are all plausible; none is sourced).

Contemporaneous context. Brocade's public position at filing was that it "cannot yet comment on whether or not the lawsuit has any merit" (spokeswoman, 2003‑05‑28) — no preliminary injunction motion appears to have been reported.

2. Pre‑trial motions, Markman, discovery, trial

I found no reported opinion, Markman order, summary judgment ruling, transfer/stay order, discovery order, or trial event in this case. That is a substantively meaningful negative, not just a research gap: the case ran roughly 16 months from filing to a no‑prejudice dismissal, and it terminated in a commercial standstill rather than on the merits. The absence of any Federal Circuit or N.D. Cal. published opinion captioned Vixel v. Brocade is consistent with a case that never reached claim construction or dispositive-motion practice in a reported way.

Caveats you should treat as open:

• I could not pull the PACER docket (case number not verified; my docket-targeted searches returned nothing before I ran out of calls). Individual docket entries — e.g., a Rule 12(b)(6) motion, a § 1404(a) transfer motion (unlikely, both parties in‑district), or a case-management/stay stipulation pending the Delaware action — may exist unrecorded in publicly indexed sources.
• No JMOL, new‑trial, or fee motion is possible in any event given the disposition below.

3. Parallel Delaware action (strategically significant)

~2003‑02‑28 / 2003‑03‑03 — Vixel v. QLogic (D. Del.). Vixel filed a companion suit against QLogic Corp. asserting the same patent family, targeting QLogic's SANbox product line. This matters because it framed the Brocade case as part of a two-front licensing campaign by a financially distressed patent holder, and because the Northern California venue for the Brocade case was noted by press at the time as "odd" for a plaintiff in this posture. The QLogic action later passed to Emulex along with Vixel. I did not verify the disposition of the QLogic case, and I am not going to guess at it.

4. Change of control: Emulex acquires Vixel (the pivot point)

2003‑10‑09 — Emulex announced agreement to acquire Vixel for ~$310 million in cash ($10.00/share, a ~17% premium to the $8.54 close). Emulex was the HBA market leader and Vixel's InSpeed embedded switch business (13 OEM design‑wins incl. HP, NetApp, Apple, Fujitsu, NEC) was complementary.

November 2003 — deal closed / tender completed. Emulex succeeded to Vixel's patent portfolio and to the Brocade suit. (Sources conflict: Emulex/Brocade's own 2004 release says "Emulex acquired Vixel in November 2003"; some contemporaneous Chinese and German trade coverage says December 2003. The announcement is firmly 2003‑10‑09.)

Strategic significance: the plaintiff that had sued Brocade in 2003 was now inside Emulex. But Emulex and Brocade were also deep commercial partners (Emulex HBAs + Brocade SilkWorm switches, co‑marketing to the same channel). Acquiring a plaintiff whose only real asset was litigation leverage against your primary go‑to‑market partner set up the 2004 resolution.

5. Settlement, standstill, and dismissal

2004‑09‑28/29 — announced. Emulex and Brocade announced an expanded SAN go‑to‑market partnership (co‑developed multi‑vendor SAN management wizard; joint channel bundling of LightPulse HBAs with SilkWorm switches) — and, packaged with it, a three‑year litigation standstill:

• Emulex and Brocade dismissed without prejudice all claims and counterclaims in Vixel Corp. v. Brocade Communications Systems (HPCwire/Emulex–Brocade release, 2004‑10‑01).
• Both parties preserved their respective rights, and neither may initiate litigation against the other with respect to their respective patents for three years (Brocade SEC filing language, as indexed: "Both parties preserved their respective rights and agreed to a three‑year standstill during which neither party may initiate litigation against the other party with respect to their respective patents").
• No license was granted and no money changed hands on the patent side — the consideration was the dismissal/standstill plus the commercial alliance. (Note: the "no license / no funds" language appears in the same Brocade excerpt in connection with the separate Brocade–McDATA settlement of 2004‑03‑05 over U.S. Pat. 6,233,236 — I could not cleanly isolate which transaction each sentence attaches to. Treat the "no payment, no license" characterization as likely but not fully verified for the Vixel/Emulex deal.)
• Both companies filed Form 8‑K disclosures with the SEC regarding the standstill.

Final disposition: dismissal without prejudice, no judgment, no verdict, no injunction, no license, no damages. The patents were not adjudicated valid or infringed.

6. Present posture / after‑effects

• The three‑year standstill ran through roughly September 2007. Emulex and Brocade (later Broadcom) remained commercial partners; no renewed assertion of the '776/'203/'007 patents against Brocade by Emulex was reported.
• The asserted patents have since lapsed. Google Patents records a "patent expired for failure to pay maintenance fees" event for the '203 patent (and the family assets are shown as expired). I verified the '203 lapse; I did not individually verify the '776 and '007 maintenance‑fee status.
• No appeal — nothing to appeal from a voluntary no‑prejudice dismissal.

7. Parallel PTAB (IPR/PGR) proceedings

None, and none could have existed at the time. The asserted patents were litigated in 2003–2004; the PTAB and the AIA trial proceedings (IPR/PGR) did not exist until the America Invents Act, effective 2012‑09‑16. The case was dismissed in 2004, eight years earlier. I found no later IPR, PGR, or CBM petition against U.S. Pat. Nos. 6,118,776, 6,185,203, or 6,470,007 — by Brocade, Broadcom, or anyone else. Any such petition would in any event have been moot as to this litigation, and the patents' apparent maintenance‑fee lapse makes later challenges uneconomic. (By contrast, pre‑AIA reexamination is theoretically possible but I found no reexamination certificate or proceeding for these patents.)

8. What remains unverified — flag before relying

1. Case number and assigned judge — not retrieved; PACER docket not pulled.
2. Docket entries 1–N (Brocade's answer/counterclaims, any motion practice, ADR/case‑management orders, the actual stipulation of dismissal and its entry date).
3. Whether any Markman/claim‑construction activity occurred — nothing found; strongly suggests none.
4. Disposition of the parallel Vixel v. QLogic (D. Del.) action.
5. Allocation of the "no license/no funds" language between the Vixel settlement and the McDATA settlement in the Brocade SEC excerpt.

Bottom line: this is a filed‑and‑settled patent case — a distressed patentee's 2003 assertion against the SAN switch market leader over QuickLoop/Fabric Assist, inherited by Emulex via the November 2003 acquisition, and extinguished in September 2004 by a no‑prejudice dismissal wrapped inside a broader Emulex–Brocade commercial alliance and a three‑year mutual litigation standstill. No merits ruling, no Markman, no trial, no verdict, no appeal, no PTAB involvement.

I'll research this case across docket sources, court opinions, and firm/litigation databases.

Bottom line up front

I was unable to confirm any attorney as counsel of record for Vixel Corporation in this case from the sources I could reach. I will not supply names that aren't grounded in a docket entry, opinion, or firm/litigation report. Here is what I verified, what I could not verify, and exactly where the answer is likely to be found.

What I verified (with sources)

The case and its posture.

• Vixel filed suit against Brocade in the U.S. District Court for the Northern District of California on Friday, May 23, 2003, asserting U.S. Patent Nos. 6,118,776 ("Methods and Apparatus for Fibre Channel Interconnection of Private Loop Devices"), 6,185,203 ("Fibre Channel Switching Fabric"), and 6,470,007 ("Interconnection System for Fibre Channel Arbitrated Loop Including Private Loop Devices"), all tracing to applications filed by Vixel CTO Stuart Berman in 1997. Accused products included Brocade's SilkWorm features QuickLoop and Fabric Assist. (Network Computing, "Vixel Slings Suit at Brocade," May 28, 2003; matching contemporaneous German coverage at silicon.de.)
• A parallel Vixel suit against QLogic was filed roughly March 3, 2003 in the same district, against the SANbox 2 line. Both were part of the same assertion campaign over the private-loop patents.
• Termination: Brocade's SEC filings confirm the matter ended in a settlement under which "[b]oth parties preserved their respective rights and agreed to a three-year standstill during which neither party may initiate litigation against the other party with respect to their respective patents." (Brocade 10-Q, via getfilings.com.) The standstill was publicly announced in 2004, after Emulex acquired Vixel in December 2003. (Chinese-language trade coverage, Sept. 29, 2004.)

Important disambiguation — these are not counsel: Two attorneys' names surfaced in my searches and neither should be mistaken for Vixel's litigation team:

• David Garrod (Patterson Belknap Webb & Tyler LLP) was quoted by Network Computing as a neutral outside commentator on the unusual choice of the N.D. Cal. as a patent venue. He had no involvement in the case.
• Vicki S. Veenker (then a founding partner of Shearman & Sterling's Silicon Valley IP group; previously Fish & Neave) appears in the N.D. Cal.'s ADR-neutral directory and her bio references lead-counsel work in patent cases in this district in that era. Her name matched a broad search, but nothing ties her to Vixel or Brocade, and she should not be listed as counsel here.

What I could not verify

• No docket sheet or opinion text was retrievable through the searches available to me. Neither CourtListener/RECAP nor free docket aggregators returned a docket for this specific caption, and I obtained no ECF/PACER entry listing appearances.
• Consequently I cannot state any of the following, and I am explicitly declining to guess: lead counsel; of counsel; local counsel; any in-house counsel for Vixel; firm names; office locations; or pro hac vice admissions. I have no name, firm, or bar number for plaintiff-side counsel that I can attribute to this case.

Why this is likely a gap, not an oversight on my part: This is a 2003 filing that settled in 2004. N.D. Cal. dockets from that period are frequently paper-era or only partially indexed in free databases, and the complaint, appearances, and settlement papers here were never the subject of a published opinion that would have named counsel. In a 2004-era standstill settlement, the dismissal filings themselves may also have been minimal.

How to close this out definitively

1. PACER / N.D. Cal. CM-ECF: Pull the full docket sheet for the case (the case number should be confirmed from the docket index rather than assumed; if the number is hard to locate, search the N.D. Cal. index by party name "Vixel" for May 2003 filings). The "Attorneys" / "Parties" tab in the docket report is the single authoritative source for counsel of record and typically shows firm, address, and the lead-vs.-local designation.
2. The parallel QLogic case (same district, March 2003) is the highest-value cross-check — the same plaintiff-side firm almost certainly represented Vixel in both, and the QLogic matter may have generated more accessible filings (e.g., a preliminary injunction motion or claim-construction papers).
3. Run a combined name search in RECAP/CourtListener for "Vixel" as a party across all years; even if this particular docket wasn't scraped, later Emulex-era filings over the same three patents may name the same counsel and confirm a continuation of representation.
4. Emulex's and Brocade's SEC filings (10-K/10-Q and proxy statements) around 2003–2004 sometimes name litigation counsel; Brocade's 10-Q, already located, discusses the settlement substance but not the firms.
5. Trade press archives (Byte and Switch, SearchStorage, eWeek, Network Computing) from May 2003 and 2004 may name the firms in longer versions of the articles; the accessible version names only the neutral commentator.

If you can provide the docket number or a PACER docket-sheet export, I can populate the requested fields — name, role, firm, office, and experience notes — directly from the appearances of record.

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

Short answer

I could not verify any counsel of record for Brocade in this case from the sources available to me, and I will not guess at names. Nothing in the public materials I retrieved (contemporaneous trade press, Brocade/Emulex SEC filings, and case-follow-up coverage of the settlement) identifies the attorneys who appeared for Brocade in Vixel Corp. v. Brocade Communications Systems, Inc. I am therefore reporting the verified case facts, flagging the counsel gap explicitly, and setting out the specific docket steps needed to fill it.

Why the counsel record is hard to pin down here

• Age of the case. Filed 2003-05-23 and resolved by a dismissal-without-prejudice roughly 17 months later (see below). This predates N.D. Cal.'s mandatory electronic filing regime, so appearance entries sit in the legacy PACER docket rather than in the modern CM/ECF HTML dockets that are indexed by CourtListener/RECAP, Justia, and similar aggregators. My searches of those aggregators returned no docket sheet for this matter.
• Thin press coverage of counsel. The 2003 trade-press coverage of the filing ("Vixel Slings Suit at Brocade," Network Computing/Light Reading, May 28, 2003) quotes only neutral commentators — e.g., David Garrod of Patterson Belknap Webb & Tyler LLP, commenting on the odd choice of N.D. Cal. and on Vixel's parallel suit against QLogic. Mr. Garrod was not counsel in the case and should not be listed as such.
• Settlement filings are deal-related, not counsel-related. The public SEC filings connected to this case describe the commercial terms, not who litigated it.

What is verified about the case and its disposition

Note: the March 5, 2004 Brocade 8-K standstill described in the search results is the McDATA standstill, not the Vixel one — a common conflation. The Vixel standstill is the September/October 2004 Emulex–Brocade one.

Counsel: status and verification path

Counsel of record for Brocade Communications Systems, Inc. — NOT VERIFIED. No attorney name, firm, role, or office location for Brocade's defense can be responsibly stated from the evidence I have. This is a documentation gap, not a sealed-filing situation as far as I can determine; the appearances simply aren't reflected in the publicly indexed sources I could reach.

To complete the record, the following specific steps should be run:

1. PACER legacy docket, N.D. Cal. Pull the full docket for Vixel Corp. v. Brocade Communications Systems, Inc. (2003 filing term). The docket number was not confirmed by my searches; do not assume one. Retrieve it from the N.D. Cal. civil case index by party name and filing date (2003-05-23), then read the caption entries on the complaint and the "Attorneys" section of the docket report, which lists lead counsel and firm/address for each party.
2. Appearance and pro hac vice entries. On the legacy docket, check entries for "Notice of Appearance," "Application for Admission Pro Hac Vice," and "Stipulation and Order" (which frequently name all counsel of record). A patent defense of this era typically shows one Silicon Valley firm plus out-of-state patent specialists admitted pro hac vice.
3. Brocade's corporate disclosure and in-house counsel. The Rule 7.1 disclosure and any corporate-representative designations will name Brocade's in-house legal contact (Brocade's General Counsel in that period) if it appears on the docket; I could not verify who held that office, so I am not naming anyone.
4. Firm-side archives. Search the websites of Brocade's known patent-defense firms of that era for a 2003–2004 case listing under "Vixel" or "Brocade." Again, I have not confirmed which firm held the engagement, so no firm is named here.
5. Confirm via the settlement papers. The Emulex and Brocade 8-Ks relating to the standstill (filed on or about Sept. 29–30, 2004) reference the case caption; they do not, however, list litigation counsel in the excerpts I retrieved.

Bottom line

• Verified: the case identity, filing date, patents, accused features, Emulex's acquisition of Vixel, and the October 2004 dismissal-without-prejudice under a three-year standstill.
• Not verified: every element you actually asked for — Brocade's lead counsel, any of-counsel/local-counsel entries, firm, office location, and experience notes. I am deliberately leaving those blank rather than populate them with plausible-sounding but unsourced names.

If you can supply the PACER docket number or a docket-sheet export, I can name the attorneys with citations to the specific appearance entries.
