Untitled case

I'll research the remaining open questions — especially the identity of the 1:02-cv-20609 defendant and the S.D. Fla. 2002 filing wave — before drafting the overview.

The Stanford NPE database appears to index this patent's litigation. Let me pull that listing and probe for 2002 S.D. Fla. defendants.

Case overview and background

The parties. The two plaintiffs occupy different rungs of the same corporate and licensing structure. Contour Optik, Inc. is the record owner of the asserted patent — the Chao brothers (Richard, the sole named inventor, and David) assigned their eyewear patents to Contour in July 1999. Aspex Eyewear, Inc. is a Delaware corporation with its principal place of business at 2755 S.W. 32nd Avenue, Pembroke Park, Florida, and it is the operating commercial entity: a distributor/supplier of eyewear that sued as the patent's "exclusive licensee" with the right to enforce. Both Aspex and its Canadian affiliate Chic Optic, Inc. (Montreal) are owned and operated by the Ifergan family, and the March 1998 Chic–Aspex license agreement — which the Federal Circuit read as conveying only then-owned patents, not future-acquired ones — is the document that generated years of standing litigation across this family of cases. So this is not a university or a classic shell NPE: the plaintiff side is a practicing eyewear business plus a related patent-holding company, suing through an exclusive-license arrangement whose scope was itself contested. (See Aspex Eyewear v. Zenni Optical, No. 09-61468 (S.D. Fla.) First Amended Complaint ¶¶ 4–10; Aspex Eyewear v. E'Lite Optik, No. 04-1292 (Fed. Cir.) (Chic–Aspex and Chao–Chic agreements).)

The patents and the accused technology. The asserted patent is U.S. Patent No. 5,737,054 ("Auxiliary Lenses for Eyeglasses"), issued April 7, 1998 to Richard Chao on Application No. 08/766,327. In one line: it claims an eyeglass device in which a magnet is secured in the middle bridge of a primary spectacle frame, and the auxiliary (clip-on sunglass) frame carries a projection extending over that bridge with a second magnet, so the two frames couple magnetically and the clip-on can be attached with one hand. The '054 sits at the head of a family the plaintiffs asserted together — U.S. Patent No. 6,012,811 (a continuation-in-part, naming David and Richard Chao, claiming two "retaining mechanisms," i.e., lens rims, joined by a bridge with a bridge magnet) and U.S. Patent No. 6,092,896 (adding a bridge cavity that receives a protrusion on the mating frame), plus the reissued RE37,545. The accused technology across the enforcement campaign was consistently the same: magnetic clip-on/snap-on sunglasses and auxiliary frames that attach at the bridge by magnets — and, critically, rimless versions of that product. The defendants in the broader 2002–2013 campaign were a cross-section of the eyewear trade, from brand licensees (Altair Eyewear, distributor of Tommy Bahama sunglasses), to licensed manufacturers (Marchon, Revolution), to retailers and online sellers (Zenni Optical, Eyeglass World, Cohen's Fashion Optical). Notably, the obviousness references that eventually killed claim 1 of the '054 on remand were Japanese Utility Model No. 3031881 (Miki) and German Patent No. 3933310 (Stemme) — i.e., the prior art was foreign magnetic clip-on eyewear.

Posture, venue, and why it matters. The case as docketed is a 2002 patent infringement action in the U.S. District Court for the Southern District of Florida, Miami Division (the "1:" prefix). Venue is unsurprising and, for the plaintiffs, deliberate: Aspex's principal place of business in Broward County sits inside the district, making S.D. Fla. the licensee's home forum and a natural companion to the 2002 filings in S.D.N.Y., C.D. Cal., and D. Nev. The S.D. Fla. docket also became the plaintiffs' preferred venue in the later enforcement waves — Judge William Zloch handled Zenni Optical (09-61468), Judge Marcia Cooke handled the Hardy Life/Marchon/Nike case (09-61515), and Magistrate Judge Robert Dubé handled Concepts in Optics (00-7067) — although no judge assignment, pleading, motion, or termination date can be confirmed for 1:02-cv-20609 itself. The case is notable for three reasons: (1) the '054 was the one patent in the family that survived Federal Circuit review on claim construction — the 2008 panel held that "frame" in the '054 is not limited to frames with rims, reversing the ruling that had defeated infringement — only for claim 1 to be held invalid for obviousness on remand (D. Mass. 2011, aff'd 484 F. App'x 565 (Fed. Cir. 2012)); (2) the S.D. Fla. progeny produced the two decisions that finally shut the campaign down — collateral estoppel in Zenni (713 F.3d 1377 (Fed. Cir. 2013), cert. denied) and the reexamination/claim-preclusion holding in Aspex Eyewear v. Marchon Eyewear, 672 F.3d 1335 (Fed. Cir. 2012); and (3) it is a pre-AIA case, so there is no IPR/PGR linkage — the parallel USPTO attack was ex parte reexamination (Altair requested reexam of the '054, with the PTO confirming the original claims; a third party's reexam of the '545 concluded in April 2008). The market context is the 1990s–2000s boom in magnetic clip-on eyewear, where a single patent family let a mid-sized Florida distributor extract a >$4 million jury verdict against Revolution and then pursue much of the rest of the industry.

Sourcing flags

• The defendant and outcome in 1:02-cv-20609 remain unverified. No PACER/RECAP docket, complaint, or order for that number surfaced. The accused-product description above is confirmed for the campaign, not for this docket.
• Counsel, judge assignment, and disposition for this docket are likewise unconfirmed (see the plaintiff- and defendant-representative sections above).
• Database inconsistency is a live risk here: the Stanford NPE litigation database indexes this patent's suits across S.D.N.Y., S.D. Fla., D. Nev., and elsewhere but does not show a 2002 S.D. Fla. entry matching 20609; the closest S.D. Fla. entries it lists are Eyeglass World (0:00-cv-07070) and Cadore Moda (1:06-cv-22210). A 2002 filing that was quickly dismissed, transferred, or consolidated is a plausible explanation, but I could not confirm it.

I'll research this specific docket aggressively, starting with attempts to identify the defendant and any docket/opinion tied to 1:02-cv-20609.

Key legal developments and outcome

1. Threshold finding on this docket (new since the prior sections)

A further round of targeted searching (case-number variants "02-20609," "02-20609-CIV," "20609-CIV," combined with party and patent terms) again produced no docket sheet, complaint, order, or opinion for S.D. Fla. No. 1:02-cv-20609. The only hit for the number string was an unrelated 2026 S.D. Fla. case (26-20609-CV-WILLIAMS, Trump v. IRS), which is a different matter entirely and confirms nothing about the 2002 filing.

Accordingly, this section cannot report the complaint, answer, Markman ruling, trial, or disposition of 1:02-cv-20609 itself. What it can do, and does below, is (a) state what the patent's litigation record establishes about the 2002 filing, (b) trace the documented chronology of the '054 enforcement campaign from 2000 to 2016 — which is where every substantive legal development on this patent actually occurred — and (c) address the PTAB/reexamination question, which for a 2002 case has a definite and documented answer.

One new documentary lead worth flagging (unverified). The S.D. Fla. Markman ruling in Aspex Eyewear, Inc. v. Designers Eyewear Studio is dated 2006-12-22 and cites docket entries in the 60s and 100s (D.E. 61, D.E. 111), which is consistent with a multi-year-old case, not a 2006 filing. If any 2002-filed S.D. Fla. Aspex matter matured to claim construction, this is the most promising candidate for matching to No. 1:02-cv-20609. Corroborating detail: Designer's Eyewear Studio appeared as amicus curiae in the Altair appeal through Richard M. Saccocio, P.A. (Plantation, FL) — an unusual posture for a stranger to the litigation. Source: https://ipmall.info/sites/default/files/hosted_resources/Markman/pdfFiles/2006.12.22_ASPEX_EYEWEAR_INC_v._DESIGNERS_EYEWEAR_STUDIO.pdf

I'll research plaintiff-side counsel for this docket. Given the prior sections' finding that the docket itself is unverified, I'll try to either confirm the docket or establish the plaintiffs' counsel pattern for the contemporaneous '054-family cases.

The 2026 hit is unrelated. Let me look for the '054 patent's litigation record and any 2002 S.D. Fla. Aspex docket.

Let me check the Designers Eyewear Studio opinion (S.D. Fla., '054/'811/'896) for its docket number and counsel, and try to locate a docket index for 1:02-cv-20609.

Bottom line

I could not verify docket 1:02-cv-20609 (S.D. Fla.), and I therefore cannot name any attorney as counsel of record for the plaintiffs in this case. Nothing I retrieved — CourtListener/RECAP, Justia, RPX Insight, the Stanford NPE database, IPMall's Markman collection, firm sites, or trade/IP press — ties a complaint, answer, appearance, or order to that case number. Naming plaintiffs' counsel here would require inventing it, which I will not do.

One important caution surfaced in the search: the only case-number hits for "20609" in S.D. Fla. were to a 2026 case, Trump v. Internal Revenue Service, No. 26-20609-CV-WILLIAMS (S.D. Fla.) (order closing case, DE 52). In other words, "20609" is a sequence number that recurs every year in that district, and any secondary-database hit bearing "20609" must be year-checked before it is treated as this 2002 docket. That is a plausible explanation for how a '054-patent litigation-record entry could have been populated with a docket number that does not resolve.

What the record does establish: plaintiffs' counsel in the contemporaneous '054 / '545 family

These are verified from court opinions and docket-derived documents, and they are the correct starting point for identifying who Aspex/Contour used on the plaintiffs' side in this era. They are analogues, not findings about 1:02-cv-20609.

Structural note on local counsel. S.D. Fla. practice in this period paired out-of-state patent firms with Miami local counsel. In Concepts in Optics the defendants did exactly that (Gary E. Lambert, Lambert & Associates, Boston, with Joseph W. Beasley, Josephs Jack, Miami). Expect the same two-firm structure on the plaintiffs' side of any 2002 S.D. Fla. Aspex filing — a lead patent firm plus a Miami notice-of-appearance firm — but I have no document naming the plaintiffs' local counsel for any 2002 S.D. Fla. Aspex docket, including 1:02-cv-20609.

Venue plausibility (already established in the prior sections, not repeated): Aspex's principal place of business in Pembroke Park, FL makes S.D. Fla. its home forum, and the family litigated there repeatedly — Aspex Eyewear v. Eyeglass World, Inc., No. 0:00-cv-07070 (S.D. Fla., per Stanford NPE database), Concepts in Optics (00-7067), Designers Eyewear Studio (Markman Dec. 22, 2006), Zenni (09-61468), Hardy Life/Marchon/Nike (09-61515). So a 2002 S.D. Fla. filing is entirely plausible; it is simply not confirmable as this docket.

Why I cannot close this on the plaintiffs' side

1. No accessible docket. PACER's S.D. Fla. CM/ECF record for 1:02-cv-20609 is the only authoritative source for appearances. No RECAP/CourtListener docket for that number surfaced.
2. Opinions would have been the backstop, and there are none. For every other '054-family case I can name the plaintiffs' counsel, because there is a published opinion or a docket-mirrored complaint with a signature block. No opinion cites 1:02-cv-20609, which is itself weak evidence that the case produced no appeal and no reported ruling.
3. Sealing is not the issue; the docket itself is. I have no indication that filings in this case are sealed — I have no indication of any filings at all.

How to close it (specific, in priority order)

• Pull the S.D. Fla. CM/ECF docket for 1:02-cv-20609 (Miami Division). If the case exists, the plaintiffs' counsel will appear in: DE 1 (Complaint signature block), any Rule 7.1 corporate disclosure statement, and every Notice of Appearance / Designation of Local Counsel.
• If the docket is closed with withdrawn counsel, the motions to withdraw name the firms.
• Cross-check the attorney names above — Nicodema / Greenberg Traurig (2000–2007 era) and Faegenburg / Lerner David (2009+ era) — against the appearance list; one of those firms is the likeliest filer if this really is an Aspex/Contour '054 case.
• If the docket does not exist or resolves to a non-patent matter, treat the metadata entry as a mis-mapped litigation-record entry (the "20609" collision with Trump v. IRS, No. 26-20609, illustrates the risk) and correct the case record rather than the counsel field.

Explicit non-attribution statement: I have not identified any attorney as counsel of record for Aspex Eyewear, Inc. or Contour Optik, Inc. in No. 1:02-cv-20609 (S.D. Fla.). Every name above is sourced to a different case in the same patent family, is labeled as such, and must not be carried over to this docket without confirming it on the docket sheet.

I'll start by trying to pin down the docket itself, since defendant-side counsel can't be named without knowing who the defendant was.

A promising new lead: a 2006 Aspex Eyewear v. Designers Eyewear Studio Markman opinion. Let me check its docket and probe whether 20609 corresponds to it or another 2002 S.D. Fla. defendant.

The Designers Eyewear Studio Markman opinion is a new lead. Let me pull its caption and case number, and search separately for any 2002 S.D. Fla. Aspex docket.

Bottom line

I could not identify counsel of record for the defendant in S.D. Fla. No. 1:02-cv-20609, because the threshold fact — who the defendant is — remains unverified. No PACER/RECAP docket sheet, complaint, answer, notice of appearance, or local-counsel designation for that case number surfaced in searching. Accordingly, no attorney can responsibly be named as counsel of record in this case, and I have not named one. What follows is (A) a genuinely new lead on the docket from this research pass, and (B) the documented defense-side counsel bench in the same patent family and, in several instances, the same court — flagged precisely as analogues, not as appearances in 20609.

---

A. New lead on the docket: Aspex Eyewear v. Designer's Eyewear Studio, Inc. (S.D. Fla.)

This is the most promising identification of 1:02-cv-20609 to date, though still unconfirmed:

• The UNH/IPMall Markman Orders Collection indexes a decision dated 12/22/2006 in "Aspex Eyewear, Inc. v. Designer's Eyewear Studio, Inc.," S.D. Florida — see the 2006 index page.
• The opinion itself (hosted at IPMall) construes exactly the three patents in this case's family — the '054, the '811, and the '896 — and addresses the terms "frame," "projection," and "retaining mechanisms." It is a substantial docket: it cites D.E. No. 111 (exhibit) and D.E. No. 61 (exhibit), meaning well over 100 docket entries by December 2006.
• That profile — an S.D. Fla. case on the '054/'811/'896 trio with a 2002-style filing date rippling out to a late-2006 Markman — is consistent with a 2002 S.D. Fla. filing, but I found no document tying the caption "Designer's Eyewear Studio" to docket number 1:02-cv-20609. I am flagging it as a lead, not a finding.

If this is the case, the defendant-side counsel is ascertainable in one step: the caption block and signature blocks of that 12/22/2006 opinion, plus the answer/counterclaim and any pro hac vice motions on that docket, will name defense counsel directly. That is the single highest-yield next pull.

---

B. Documented defense-side counsel in the same patent family (NOT confirmed for 1:02-cv-20609)

These are the attorneys of record for defendants in the Aspex/Contour magnetic-eyewear campaign, drawn from published Federal Circuit opinions and trade press. None is confirmed to have appeared in 1:02-cv-20609, and I am deliberately not asserting any of them as counsel of record here.

Same court (S.D. Fla.)

Other circuits (same patents, same campaign)

Practice-structure note: in these S.D. Fla. matters the defense side followed the same pattern as the plaintiffs — out-of-state patent litigation counsel admitted pro hac vice, paired with a Florida local counsel of record. Any 2002 S.D. Fla. defendant would almost certainly have appeared through that two-tier structure, which is why a bare search for "defendant's counsel" without the docket is unlikely to resolve.

---

C. Why the gap persists, and what would close it

1. I have no PACER/RECAP access to the docket. Free aggregators (CourtListener/RECAP, UniCourt, Justia) did not surface 1:02-cv-20609; 2002-era S.D. Fla. filings are frequently paper-era and only partially digitized. I found no evidence the file is sealed — the gap is a records/coverage problem, not a sealing problem.
2. The caption "Designer's Eyewear Studio" is the live thread (Part A). Pulling that 12/22/2006 opinion's full text and the underlying docket would likely resolve both open questions — defendant identity and defense counsel — simultaneously.
3. If that lead fails: pull the S.D. Fla. docket for 1:02-cv-20609 directly and read (a) the complaint caption, (b) the answer/counterclaim, (c) any notice of appearance or designation of local counsel, and (d) any pro hac vice motions. Those four documents will name every defense attorney of record.

What I did not do

I did not infer, invent, or "most likely" any attorney into the role of counsel of record for the defendant in 1:02-cv-20609. The names in Part B are sourced to specific published opinions and trade coverage for other dockets; attributing any of them to 1:02-cv-20609 without the docket sheet would be fabrication, and I have flagged each as unconfirmed rather than presenting it as an appearance.
