US 8615815

I'll run the requested searches first, then summarize against the authoritative full text I already have.

Let me run a few more targeted checks on litigation/docket history and the inventor name discrepancy.

Search-execution note (important)

I ran the searches you asked for. I do not have direct, authenticated query access to USPTO PatentCenter/EFS or the CAFC docket (PACER/CM-ECF); web_search is a general web index. Results:

• "8615815" patent infringement lawsuit CAFC 2026 → zero results.
• "8615815" patent PTAB IPR litigation docket → returned only the Google Patents page, not a docket.
• Searches pairing "8615815"/"8,615,815" with "Federal Circuit" → no CAFC opinion, appeal, or docket entry surfaced.
• What did surface was the USPTO-hosted full-text PDF (patentimages.storage.googleapis.com/…/US8615815.pdf), FreePatentsOnline, Google Patents, and aggregators.

Conclusion on litigation: I found no evidence of any litigation, PTAB proceeding, or CAFC 2026 docket activity involving US 8,615,815. I cannot affirmatively certify the absence of a proceeding — treat that as "no public trace found," not as a verified negative. Aggregators show zero lifetime renewal fees paid.

US 8,615,815 B2 — bibliographic data

Abstract (verbatim substance): A brief-style elastic spandex undergarment for a portly person with an enlarged abdomen, with a high-cut back and low-cut front so the waistband crosses the small of the back and passes under the abdomen. It adds an auxiliary elastic waistband to hold abdominal hernias in and an attached supporting undershirt; the briefs' and auxiliary band's elasticity press small hernias back into the abdominal cavity. For males, a hole lets the penis and scrotum project to avoid compression while allowing a snug pressure fit across the front. Usable as sleepwear and athletic wear.

Independent claims in plain language

Claim 1 — brief + ovoid hole + rear-attached belly band

1. A brief-style undergarment of interconnected spandex elastic panels covering the pubic, hip-side, perineal and buttock areas.
2. The panels have a circular top edge to which an elastic waistband is sewn, worn so it passes over the small of the back and downward under the abdomen (high-back/low-front, not horizontal).
3. An ovoid (egg-shaped) hole in the pubic panel receives the penis and scrotum. Its long axis is vertical, and its upper arc has a larger radius than its lower arc.
4. Functional limitation: the panels + waistband + hole must cooperate to apply "strongly palpable pressure" to the pubic and perineal surfaces, and no pressure to the penis or scrotum.
5. A second elastic band (the "belly band") wide enough to cover an abdominal hernia, positioned directly above the waistband, sewn to the waistband at the back only — so the front and side portions can be moved up or down over a hernia.

Claim 3 — same core as claim 1, plus continuous-loop waistband and sewn-on undershirt

• Frames the article as a close-fitting brief for a human male.
• Adds that the elastic panels extend up to the waistband, and the waistband is a continuous unbroken loop sewn to the upper edges of the panels (claim 1 says only "circular top edge").
• Requires the ovoid hole be vertically oriented with the upper arc larger than the lower arc, and the lower arc oriented downward toward the perineal panel.
• Repeats the "strongly palpable pressure / no pressure to penis or scrotum" limitation.
• Adds the belly band as "pivotally attached by being sewn to said waistband at the back only," with front and side portions movable up and down.
• Adds an undershirt with shoulder straps, its torso-surrounding portion's lower edge sewn to the waistband continuously along the entire top edge of the waistband.

Dependent claim 2 (on claim 1) adds just the undershirt element: shoulder straps plus a torso portion whose lower edge is sewn to the waistband, continuous along the entire top edge.

Accuracy flags for a diligence review

• Claim-numbering gap: independent claim 3 uses sub-parts (a)–(f) then jumps to (h); there is no sub-part (g). That is literal in the text — it should not be "fixed" when quoting the claim.
• Reference-numeral drift across the family: in the 2013 patent index, 8 = "the hernia belly band in place" and elements 9 and 14 = "Not used." In the earlier published application (US 2009/0178182 A1), 8 = the usual waistband position, 9 = the preferred waistband position, and 14 = upper waistband. Element (10) is listed as "Not used" in the 2013 index yet is used in the specification prose ("the back 2 to 5 inches higher (10) than the front"). Anyone mapping numerals to parts must use each document's own index.
• Third-party aggregator metadata is unreliable here. Unified Patents' page for US 2012/0253256 A1 lists "Priority Date 2004-06-15," "Application Date 2012-04-01," "Grant Date 2012-10-03," and a blank grant number. All four contradict the authoritative front-page/Google Patents data (2004-06-16; 2012-04-02; 2013-12-31). Do not rely on that record.
• Closest cited art (44 references cited): Nelkin US 4,416,272 (combination underpant and hernial truss — the specification's main distinguisher, on grounds of where the secondary band attaches, front vs. back, and pot-belly fit); Lerman US 2,684,673 (non-elastic surgical dressing support with a penis/scrotum hole); Linneros US 1,263,576 (buttoned-on undershirt over non-elastic shorts); Thrower US 5,875,495 (male undergarment, knit cotton, symmetrical oval hole).
• What I am not asserting: I have no authoritative confirmation of any 2026 CAFC appeal, IPR, or district-court case for this patent, and no confirmation of current ownership/chain-of-title beyond "Individual." Those points should be verified in USPTO PatentCenter, the USPTO Assignment database, and PACER/CM-ECF if they matter to your analysis.

Let me try a few more targeted searches to be thorough.

Findings: Litigation involving U.S. Patent No. 8,615,815

No litigation is known to involve U.S. Patent No. 8,615,815.

I searched for the specific number 8615815 (and the comma-formatted 8,615,815) across litigation-oriented sources — Unified Patents' litigation resources, CourtListener/RECAP, Docket Alarm, Justia, and general PACER/CAFC-style queries — plus inventor-name searches (Dahlquist). The results returned no district-court complaint, no CAFC appeal, and no PTAB proceeding (IPR/PGR/CBM) naming this patent.

Why that result is consistent with the patent's record

The authoritative patent data supplied shows a profile typical of a never-litigated, individual-owner patent:

Legal-status events of note:

• 2013-10-08 — PA: "Patent available for licence or sale." (A signal the owner was seeking licensees rather than, apparently, asserting in court.)
• 2017-08-11 — REMI: Maintenance fee reminder mailed.
• 2018-01-29 — LAPS: Lapse for failure to pay maintenance fees.
• 2018-01-29 / 2018-02-20 — EXP/FP: Patent expired for nonpayment under 37 C.F.R. § 1.362, effective 2017-12-31 (i.e., at the 3.5-year maintenance-fee window).
• Google Patents lists status as "Expired – Fee Related."
• The "Cited By" list shows only later patents/publications citing it as prior art — not litigation.

Important caveats

1. Search limitation. I was able to reach patent-text and general sources but did not obtain direct database confirmation from every paywalled docket system (e.g., full PACER, Docket Navigator, Lex Machina) before my searches were cut off. My conclusion rests on the public sources above plus the absence of any litigation references in the patent's own Google Patents/FreePatentsOnline records.
2. A "no litigation found" answer is a negative finding, not a certified negative. Small individual-inventor suits, state-court actions, or very recent filings could exist without appearing in the sources searched. A definitive check would require querying PACER's full docket index and a commercial service (Lex Machina / Docket Navigator / Unified Patents litigation portal) by patent number.
3. Note on identifiers. Per the strict rule, I have not "corrected" any identifiers. One point worth flagging literally: the granted patent's own claim text and the earlier applications use slightly different identifiers for the band (e.g., the older publication used element 14 for "upper waist band," while the granted patent's index redefines element 8 as "the hernia belly band in place" and marks 9, 10, 14 as "not used"). This is an internal inconsistency in the documents, not a litigation matter.

Bottom line

• Plaintiff(s): None identified
• Defendant(s): None identified
• Jurisdiction: None identified
• Case number: None identified
• Filing date: None identified
• Outcome/status: Not applicable — no litigation known

If you need a certified-negative confirmation, the next step would be a direct Docket Navigator / Lex Machina query on patent number 8,615,815 plus a PACER "patent" nature-of-suit search, which the sources I could reach do not expose for free.

I'll verify the structured data's "no proceedings" finding against the public record before writing up.

Proceedings overview

Zero AIA trial proceedings are on file for US 8,615,815. The structured USPTO ODP block reports no IPR, PGR, or CBM involving this patent, and my independent web checks returned no petition, institution decision, Final Written Decision, or Federal Circuit appeal tied to the patent or to its owner (Daryl Lervy Dahlquist) — so the breakdown is 0 active / 0 invalidated / 0 sustained / 0 settled / 0 institution-denied, and there is no proceeding section to write below. The defensive significance is therefore not "the patent has been hardened by surviving IPRs" — it is that the patent was never tested at the PTAB because it was never worth testing: it lapsed for non-payment of maintenance fees effective 2017-12-31 and is off the fee-paid register, so a demand letter citing it is asserting a patent with no remaining enforceable life.

No proceeding sections generated

I will not manufacture entries. To be explicit about what I searched and what I found:

• ODP / structured data (canonical): no AIA trial proceedings for US 8,615,815 as of the most recent ingest.
• Google Patents "Cited By" and litigation-linked listings for the patent: only patent citations (e.g., US 2012/0172780 A1, USD838931S1, EP3569203A1, US11304455B1, US11491041B2) — no PTAB trial numbers, no Board decisions.
• Targeted searches for "8615815" IPR, 8615815 PTAB, and Dahlquist infringement litigation: no hits to a Board proceeding or to a district court docket.
• I did not find any Unified Patents (or other defensive aggregator) challenge in the chain; the patent does appear in Unified's public patent portal page (https://portal.unifiedpatents.com/patents/patent/US-20120253256-A1), but that is a catalog entry, not a filed proceeding. Treat that as a signal of monitoring, not of challenge.

If a proceeding exists that post-dates the ODP ingest, I could not surface it, and I am flagging that as an open verification item rather than asserting it exists.

Strategic summary

Claim status. Because there is no IPR, no claim of US 8,615,815 has been canceled and none has been sustained by the Board. All three issued claims — independent claim 1, dependent claim 2, and independent claim 3 — are untested at the PTAB. That is a two-edged fact: a defendant cannot point to a cancellation, but also faces no adverse FWD or appeal decision that would constrain claim construction. Claim 1 covers the brief with the high-back/low-front spandex waistband plus the ovoid pubic hole and the back-only-sewn second elastic band; claim 2 adds the sewn undershirt with continuous attachment along the entire top edge of the waistband; claim 3 restates claim 1/2 elements in independent form (note the drafting defect: the limitations run "e … f … h", with no "g" — a § 112(b) hooks for indefiniteness that no tribunal has yet addressed).

Estoppel landscape. There is no § 315(e)(2) estoppel against anyone, because no petitioner ever instituted an IPR. Practically, this means every prior-art ground remains fully available to a defendant: the references already of record (Nelkin US 4,416,272; Lerman US 2,684,673; Linneros US 1,263,576; Thrower US 5,875,495, all discussed at length in the specification itself), the broader 44-reference citation set (including Glaper US 4,059,103, Heron US 5,870,779, Brill US 6,047,408, and the Fla Orthopedics hernia briefs US 6,622,719 / USD482,512), and any art a defendant locates independently. There is no prior IPR that would let a plaintiff argue a defendant "reasonably could have raised" anything before. The absence of estoppel is the mirror image of the absence of a free invalidity roadmap — a defendant must build the § 102/§ 103 case from scratch.

Pattern signals. No same-petitioner pattern exists (no petitioner at all). No PTAB appeals by the patent owner exist. No aggregator is in the chain. The patent's family history shows a prosecution pattern rather than a litigation pattern: original application 11/147,693 ("Garment for Enhancing Male Sexual Performance," 2005) abandoned; continuation 12/322,648 (2009) abandoned; continuation 13/506,184 (2012) granted 2013-12-31. The grant came nine years after the 2004-06-16 priority date, and the owner (an individual) never commercialized or asserted it at scale. Legal events show a 2013-10-08 "Patent available for licence or sale" filing and then a 2017-08-11 maintenance-fee reminder and 2018-01-29 lapse.

Recommended next steps

1. For a defendant receiving a demand citing US 8,615,815: check enforceability before invalidity. USPTO legal events show LAPS / EXP — "PATENT EXPIRED DUE TO NONPAYMENT OF MAINTENANCE FEES UNDER 37 CFR 1.362," effective 2017-12-31, with a later "Lapsed due to failure to pay maintenance fee" entry. Google Patents lists the anticipated expiration as 2025-06-08 (20 years from the 2005-06-08 filing of parent 11/147,693). Either way, the patent is not in force today (2026-09-28). An expired patent cannot support injunctive relief, and pre-suit damages are limited by the 6-year lookback of 35 U.S.C. § 286 — a lookback that now reaches only conduct after roughly 2020-09-28, i.e., after the patent lapsed. Confirm the fee history directly at USPTO Patent Center for application 13/506,184 before responding.
2. Because there is no PTAB record, there is no FWD to link to and no Board disposition to quote. Do not represent to a court or opposing counsel that claims have been canceled — they have not. Any invalidity position must be built as a fresh § 282 defense (anticipation/obviousness), and the specification's own admissions about Nelkin, Lerman, Linneros, and Thrower are the natural starting point for a § 103 narrative.
3. Verify the "no proceedings" finding at the source before relying on it. Run the patent number and the owner name through PTAB E2E (https://ptab.uspto.gov) and the PTAB Decisions database (https://developer.uspto.gov/ptab-web/), and CourtListener (https://www.courtlistener.com) for any Federal Circuit appeal. If any older or recently-filed proceeding surfaces that the ODP ingest missed, it should be added to this file with the proceeding number, panel, grounds, and outcome — but on the evidence available now, the correct statement is that there is no PTAB activity on file.
4. Treat the absence of IPRs as an information signal, not a comfort. A 2013 patent with a narrow, individual-owner family that lapses in 2018 never attracted an IPR because there was no commercial assertion to defend against. If a new plaintiff has acquired or revived an interest in this family, expect the assertion to be tested for standing and for the fee/expiration status first. Also check whether any continuation or reissue in the family carries a live term — the 13/506,184 chain is what matters, and the family listing shows no later live member.

Constraint note: I found no proceeding numbers, no judge panels, no institution decisions, no FWDs, no settlements, and no CAFC docket numbers for this patent, and I have not invented any. The only hard citations I can stand behind are the patent's own text and legal-events record (https://patents.google.com/patent/US8615815/en) and the source listings cited above.

I'll research the assignment/ownership record for US 8615815.

Ownership & Assignment Analysis — US 8,615,815 B2

Verification links: USPTO Assignment Center · Assignment Search (legacy UI) · Google Patents record · FreePatentsOnline record

Inventors

I am reporting these three renderings literally, per the operating rules; I am not treating them as a correction of one another. Whether they are the same natural person is not something the record in front of me establishes, though the shared priority lineage (see below) strongly suggests it.

Patterns worth noting:

• Solo inventor, pro-se prosecution. The FreePatentsOnline bibliographic data lists the "Attorney, Agent or Firm" as "DARYL DAHLQUIST" — i.e., the inventor prosecuted his own application. There is no outside counsel of record on the patent. This is a material fact for the assignment analysis below: with no patent attorney involved at filing, there is also no obvious correspondent who would later file NPE-style recordings.
• No employer relationship surfaced. An earlier, unrelated patent naming "Dahlquist, Daryl Leroy" appears in the family citation list — US 6,027,464, "Sleeping and therapy system with a person hydraulically supported by immersion in water." An inventor holding patents in water-immersion therapy and in hernia undergarments, with no corporate assignee on either, is consistent with a lone independent inventor rather than an employee of a garment or medical-device manufacturer. I could not determine an employer with confidence, and I will not guess one.
• The premise's "all inventors departing within 12 months" pattern is not applicable — there is a single inventor who retained ownership (see below), so there was no co-inventor group to fragment.

Original assignee

Original assignee (as listed): Individual — Daryl Dahlquist.

• Google Patents lists Original Assignee: "Individual" and Current Assignee: "Individual."
• The Chinese agricultural patent index likewise records the 专利权人 (patentee) as Daryl Dahlquist.
• Primary line of business: none — this is an unassigned individual holding, not a company asset.
• Product embodying the claims: I found no evidence of a commercial product shipping under this patent. The inventor's own 2013 legal event "Patent available for licence or sale" (see below) suggests he was seeking a manufacturer/licensee, not operating a business around it. There is no brand, no retail listing, and no DBA surfaced.
• Current status: Individual owner; the patent is Expired – Fee Related. Maintenance fees lapsed and the patent expired effective 2017-12-31 (the 3.5-year window). No successor entity acquired it before or after lapse.

Assignment timeline

There are no recorded assignments for US 8,615,815.

I could find no reel/frame entry for this patent in either the USPTO Assignment Center or the Google Patents legal-events table. Consistent with that: the Google Patents legal-events log for this patent contains only the following entry types, none of which is an assignment:

Important distinction: the 2013-10-08 "PA – Patent available for licence or sale" entry is a public notice of availability, not a recorded transfer. It is not evidence that a license or sale was executed, and it is not an "Assignment" conveyance. I am flagging it because it is the closest thing to a commercialization signal in the record and is easily mistaken for one.

Consequence under your instructions: because the Assignment Center shows no records beyond the original (never-assigned) filing, the chain-of-title reduces to a single link — inventor → inventor — and per the conditional instruction I stop the formal assignment analysis here. Two things follow directly from that:

1. No post-issuance ownership change ever occurred. The "Original Assignee: Individual" and "Current Assignee: Individual" fields agreeing confirms this.
2. No correspondent/attorney of record for any recording exists, because no recording was ever filed. There is therefore nothing to cross-match against a Unified Patents / RPX NPE-counsel list.

(I did not obtain a machine-confirmed zero-result screenshot from assignmentcenter.uspto.gov — my query budget was exhausted before a direct database query completed. The negative finding rests on the absence of any assignment event in the Google Patents legal-events table plus the "Individual/Individual" assignee fields. Treat this as a high-confidence but not certified negative.)

NPE / troll-pattern signals

(Assessed notwithstanding the no-records finding, because a null result against these signals is itself the answer.)

Verdict

Insufficient data — effectively an unasserted individual holding that has now lapsed.

The record contains no recorded assignment at all: Google Patents shows Original Assignee and Current Assignee both as "Individual" with a legal-events log limited to a 2013-10-08 "Patent available for licence or sale" notice and the 2017–2018 maintenance-fee lapse (expiry effective 2017-12-31), and the patent was prosecuted pro se by the named inventor. With zero transfers, zero NPE-chain links, and zero litigation, none of the eight troll-pattern signals is present — the patent simply expired in the hands of its original individual owner. Because the governing condition of "no Assignment Center records beyond the original filing" is met, I have stopped after the assignment timeline as instructed; the sections above are included only so the null result is auditable rather than merely asserted.

Contradictions flagged: none with the prior litigation section. That section's rendering of the inventor name ("Daryl Lervy / Daryl Leroy") and its note about element-numbering drift (element 14 = "Upper waist band" in parent publication US 2009/0178182 A1, versus "14. Not used" in the granted patent's index while element 8 is redefined as "the hernia belly band") are both confirmed by the FreePatentsOnline and Google Patents records. That numbering drift is a document-drafting artifact of the continuation chain — it is not an ownership issue and should not be read as evidence of any assignment.

I'll verify the key prior-art references against live sources before mapping them to the claims. Let me run several targeted searches.

Prior-Art Analysis — U.S. Patent No. 8,615,815 B2

0. Record identification (exact-number check)

I construed the search strictly on the number 8615815 (no fuzzy/near-number matching). The record located is:

The application chain is: 60/580,115 (2004-06-16) → 11/147,693 (2005-06-08) → 12/322,648 (2009-02-05, abandoned) → 13/506,184 (2012-04-02).

Caveat on the search: I reached the patent-text record (Google Patents, FreePatentsOnline, Justia, patentimages) but did not obtain a direct USPTO PatentCenter/Global-Dossier screen for every one of the 44 cited references. The citation list below is taken from the authoritative granted-patent text supplied, which is the correct pre-AIA "References Cited" list for this patent.

Internal inconsistency flagged (not auto-corrected): the granted patent's element index states "9. Not used. 10. Not used. 14. Not used.", yet the specification body uses "(10)" for "the back 2 to 5 inches higher (10)." The earlier sibling publication (US 2009/0178182 A1) used element 14 for the "upper waist band." These identifiers are reproduced literally here; they do not affect the anticipation analysis below.

1. Applicable § 102 framework

The patent carries a 2004-06-16 priority date and was granted under the pre-AIA statute (the post-AIA first-inventor-to-file provisions apply only to applications filed on/after 2013-03-16). The controlling subsections are therefore:

• § 102(a) — known/used by others, or patented/published, before the invention date (≈ priority date, 2004-06-16).
• § 102(b) — patented/published more than one year before the effective U.S. filing (critical date ≈ 2003-06-16).
• § 102(e) — U.S. patent granted on an application filed before the applicant's invention date (e.g., US 7,028,703; US 7,788,739).

Legal standard applied: a single reference anticipates only if it discloses every element and limitation of the claim, arranged as claimed. A reference that discloses some elements is not anticipating; it is at best § 103 material. I note this explicitly because the user's framing ("which claim(s) it potentially anticipates") invites element-mapping, and I do not want the mapping to be read as a finding of anticipation.

Claim 1 — element decomposition

Claim 3 — adds to Claim 1

• 3(b) waistband is a continuous unbroken loop sewn to the upper edges of the panels; plus 3(h) an undershirt with shoulder straps whose torso portion lower edge is sewn continuously along the entire top edge of the waistband.

Claim 2

• Undershirt with shoulder straps; torso-surrounding portion lower edge sewn to the waistband continuously along the entire top edge.

2. Element-by-element mapping — the four references the patentee itself discusses

These are the only four references the specification argues against, and they are the correct starting point.

2.1 US 4,416,272 — Nelkin (H.G. Enterprises) — most relevant reference

• Citation: U.S. Pat. No. 4,416,272, "Combination underpant and hernial truss," Nedwyn R. Nelkin / H.G. Enterprises. Priority 1981-04-24; granted 1983-11-22.
• Disclosure (verified against the PDF/Google Patents): an elastic Spandex brief with front 6, rear 8, side 9/10 and crotch 13 panels defining leg holes 14/15; a waist-encircling elastic top band 18 sewn to the brief; internal hernia pads 3 in pockets; and a second, longitudinally elastic belt 4 that encircles the brief and is "secured to the brief 2 only at the front portion 6", with the rear portion "free to move upwardly and downwardly at the rear portion of the brief." There is also an open-mesh genital pocket 24 with an unsewn central opening for urination.
• § 102 mapping:
  • 1(a): substantially disclosed except the high-back/low-front sloping waistband — Nelkin's waistband 18 is a conventional horizontally worn band. → no anticipation.
  • 1(b): not disclosed — Nelkin has a mesh genital pocket/flap (24/26), not an ovoid hole with a larger upper arc. → no.
  • 1(c): pressure result arguable, but the "no pressure to penis/scrotum" cooperation is not the disclosed mechanism.
  • 1(d): disclosed in inverse — Nelkin has the second belt, but it is sewn at the front and free at the back, whereas claim 1 requires back-only attachment with front/side adjustability. This is exactly the distinction the patentee argues in the Background section ("The Nelkin secondary band (4) is fastened to the garment at the front, not the back…").
• Conclusion: Nelkin is the closest art and is strong § 103 material against claims 1 and 3, but it does not anticipate any claim because it lacks 1(a)'s high-back/low-front waistband, 1(b)'s ovoid hole, and 1(d)'s back-only attachment.

2.2 US 5,875,495 — Thrower

• Citation: U.S. Pat. No. 5,875,495, "Male undergarment," John H. Thrower. Priority 1997-10-07; granted 1999-03-02.
• Disclosure: knit tubular body 12 with front 16, back 18, crotch 20; waistband 25/26; a "vertical oval opening 24" in the front area through which the penis and scrotum pass; an outer genital-covering panel 14 forming pocket 40; a partial waistband 38 at the top of panel 14. The specification expressly concedes the "wider portion being vertical" oval opening and the knit (non-spandex) construction. The patent's Background distinguishes it: Thrower's hole is a symmetrical oval, not ovoid, and the tubular portion is knit cotton with "no spandex content" (only front covering 14 / partial waistband 38 are elastic).
• § 102 mapping:
  • 1(b): partially disclosed — vertical oval genital opening, but symmetrical (upper arc radius = lower arc radius), so it does not meet "upper arc edge having a larger radius than said lower arc edge." → no anticipation of 1(b).
  • 1(a), 1(d), 3: not disclosed (no high/low waistband; no second back-sewn abdominal band; no undershirt sewn to the waistband).
• Conclusion: Relevant § 103 art on the genital-opening concept; does not anticipate any claim.

2.3 US 2,684,673 — Lerman

• Citation: U.S. Pat. No. 2,684,673, "Surgical dressing support," Samuel Lerman. Filed 1951-06-13; granted 1954-07-27.
• Disclosure: a non-elastic binder/support for surgical dressings with a hole admitting the penis and scrotum, drawn as an ovoid with the larger radius on the upper side. The specification itself characterizes it: "There is no elasticity anywhere," and the ovoid shape "was probable that the shape was not selected for function."
• § 102 mapping:
  • 1(b): the ovoid, larger-upper-radius genital hole is disclosed (pictured). → this is the single most on-point disclosure of the shape limitation of 1(b), but it is a drawing-only disclosure in a non-elastic binder.
  • 1(a): fails — no elastic/spandex panels, no elastic waistband.
  • 1(c), 1(d), 2, 3: not disclosed.
• Conclusion: Relevant to 1(b) only; no anticipation of any claim as a whole.

2.4 US 1,263,576 — Linneros

• Citation: U.S. Pat. No. 1,263,576, "Undergarment," Alfred E. Linneros. Filed 1917-06-29; granted 1918-04-23.
• Disclosure: a combination of non-elastic shorts (6) with a hole (10) and a connected undershirt (5). The specification notes the undershirt is buttoned at 4 points, not sewn, to the shorts; the buttoned shoulder straps are the only support; there is no waistband (a selvedged/hemmed edge is not deemed a waistband).
• § 102 mapping:
  • Claim 2 / 3(h): discloses a shorts + undershirt with shoulder straps combination, but the attachment is buttons, not continuous sewing, and there is no elastic waistband to sew to. → no anticipation.
  • 1(a)-(d): not disclosed.
• Conclusion: Relevant to the "attached undershirt" concept behind claim 2; no anticipation.

4. Bottom line

1. Exact record confirmed: the search returned US 8,615,815 B2 only; no near-number record was substituted.
2. No cited reference anticipates claims 1, 2, or 3 as a whole. Every reference fails on at least one limitation:
   • The combination of (i) a high-back/low-front sloping spandex waistband, (ii) an ovoid hole with a larger upper arc, (iii) the pubic/perineal-pressure–no-penis-pressure cooperation, and (iv) a second abdominal band sewn to the waistband at the back only is not disclosed in any single reference.
3. Most relevant prior art, ranked:
   • US 4,416,272 (Nelkin) — closest; anticipates nothing, but is the primary § 103 reference (spandex brief + second belt). Key distinguishing feature: Nelkin attaches its second belt at the front (adjustable at the back); claim 1 requires the reverse.
   • US 5,875,495 (Thrower) and US 4,759,355 (Thrower) — vertical genital opening, but symmetric oval, not ovoid.
   • US 2,684,673 (Lerman) — the ovoid, larger-upper-radius hole, but in a non-elastic binder.
   • US 1,263,576 (Linneros) — undershirt + shorts combination, but buttoned, non-elastic, no waistband (relevant only to claim 2).
   • US 6,622,719 (Fla Orthopedics) — elastic hernia brief that itself distinguishes Nelkin; useful § 103 art on 1(a).
4. Two references warrant a date/eligibility flag: US 7,578,009 is not available as prior art against the 2004-06-16 priority (its 2005-12-12 priority post-dates it), and US 2,684,637 (gear pump) is non-analogous mechanical art with no garment relevance despite appearing in the citation list (and without an examiner-citation asterisk).
5. Caveats: (a) I could not obtain a direct USPTO PatentCenter/Global-Dossier view for every one of the 44 references, so the citation data is taken from the authoritative granted-patent text; (b) "potentially anticipates" in the table is used in the element-disclosure sense — no reference actually anticipates any claim; (c) identifiers are reproduced literally and not auto-corrected (see the "9/10/14 — Not used" inconsistency noted in § 0).

I'll pull details on the most claim-relevant prior-art references before building the § 103 analysis.

Glaser US 4,059,103 is a significant find — a rear-attached elastic abdominal band with a genital opening. Let me pull the remaining claim-critical references.

I've hit the search-step limit, so I'll build the analysis on the prior-art section of the patent page itself plus the reference texts I did retrieve (Nelkin '272, FLA '719, Glaser '103, Thrower '495, Lerman '673). Where I rely only on the patent's own characterization of a reference, I say so.

Obviousness Analysis — US 8,615,815 B2 under 35 U.S.C. § 103

1. Governing framework and the applicable statute

US 13/506,184 was filed 2012-04-02, before the AIA first-inventor-to-file provisions took effect (2013-03-16). Pre-AIA § 103(a) therefore governs, and pre-AIA §§ 102(a)/(b)/(e) define the prior-art universe. All of the primary references below are § 102(b) art by decades except FLA '719, which is § 102(a)/(e) art on its 2002-11-12 filing date.

The controlling test is Graham v. John Deere Co., 383 U.S. 1 (1966) — scope and content of the prior art, differences between the claims and the art, level of ordinary skill, and objective indicia — applied as refined by KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398 (2007).

Level of ordinary skill (PHOSITA). A designer of knit/elastic undergarments and soft-goods orthopedic supports with roughly 2–5 years of experience in pattern-making for stretch garments, familiar with spandex (elastane) fabrics, waistband construction, and the design constraints of hernia trusses and support briefs. The art here is mechanical/garment-construction art, not surgery; the specification itself treats the problem as a pattern-cutting and band-placement problem (it even says the "pattern for cutting can be essentially the same as for women's swimwear").

Claim construction assumptions relevant to § 103.

• "Strongly palpable pressure … and no pressure to the penis or scrotum" (§ 1(c), 3(e)) is functional language. Under In re Schreiber, 128 F.3d 1473 (Fed. Cir. 1997) and In re Best, 562 F.2d 1252 (CCPA 1977), a prior-art structure that inherently possesses the recited capability meets the limitation, and the burden shifts to applicant to prove otherwise. A snug spandex brief plus an externalizing genital opening inherently produces this pressure profile.
• "Sufficient width to cover an abdominal hernia" is a relative dimension tied to the intended body region; Nelkin claim 3 uses the near-identical phrase "sufficiently wide to cover substantially all of said truss pad."
• "Sewn to said waistband at the back only" (§ 1(d), 3(f)) is a location-of-attachment limitation — a classic design-choice/mechanical-reversal candidate under In re Harza, 274 F.2d 669 (CCPA 1960) and In re Kuhle, 526 F.2d 553 (CCPA 1975).

2. The prior art of record (the page's "Citations (44)" section), grouped by what it supplies

Group A — Elastic spandex brief with an elastic waistband

Group B — Elastic band anchored at the back only, sweeping the abdomen, endlessly positionable

This is the single most damaging reference in the record, and it appears to have been cited but never substantively applied during prosecution. Every structural element of claim 1(d) — elastic, wide, abdominal, rear-only attachment, front/side portions freely movable up or down — is disclosed there, and Glaser even states the reason (adjustability over the region needing support).

Group C — Ovoid/oval externalizing genital opening

Note the direction of the disclosure: the applicant's own specification concedes that Thrower + Lerman together disclose the claimed ovoid geometry — a vertically oriented opening (Thrower) whose upper arc is larger than its lower arc (Lerman). The applicant's only distinction is why the shape was chosen ("It is probable that the shape was not selected for function"). That is not a patentability distinction: § 103 does not require the reference to recognize the reason its geometry works. In re Kemps, 97 F.3d 1427 (Fed. Cir. 1996).

Group D — Undergarment/shirt combination and shoulder-strap support

Group E — Remaining cited art

Forty-four references are cited, including King US 792,424 (truss), Burnell US 1,992,351 (garment), Ernstorff US 2,842,129 (voiding shorts), Denbo US 2,872,685 (man's undergarment), Atlee US 3,517,666, Lehman US 3,621,846 ("Mack II briefs"), Chung US 4,345,337 and US 6,038,703, Yi US 4,377,008, Nishimura US 4,660,551, Brown US 4,669,130, Maddux US 4,697,592, Webster US 4,870,958, Angheluta US 5,029,345, Pudlo US 5,618,279, Richerson US 5,647,065, Li US 5,651,144, Edenfield US 5,819,323, Heron US 5,870,779 (undergarment with testicle pouch and genital space), Brill US 6,047,408, Lyden US 6,243,880 / US 6,353,940, Takenaga US 6,868,850 ("Hernial truss"), Fla Orthopedics US 6,622,719 / USD482,512, Della Ratta US 7,024,703 / US 7,788,739, and Boston US 7,578,009. Caveat: I retrieved full text for Groups A–D only; the Group E characterizations rest on the patent-office titles/abstracts in the record, with the exception of US 6,868,850 and US 2,593,262, for which my searches were cut off. I flag that rather than assert their contents.

3. Claim 1 — element-by-element mapping

Result: every limitation of claim 1 is disclosed across Nelkin + Glaser + Thrower + Lerman, with the sole arguable gap being the sloped (high-back/low-front) waistband path.

4. Grounds of rejection and the motivation to combine

Ground 1 (primary): Nelkin '272 in view of Glaser '103; further in view of Thrower '495

The combination. Take Nelkin's spandex brief with its sewn elastic waistband (18) and its wide, elastic, hernia-covering belt (4) — but attach belt 4 at the back rather than the front, as Glaser expressly teaches, and provide Glaser's oval penis/scrotum opening in the front panel, oriented as Thrower teaches.

Why the PHOSITA would combine them — articulated rationales (KSR prongs):

1. Same field of endeavor, same problem, same solution family. Nelkin and Glaser are both combination undergarment/hernia supports classified in A61F5/24 (trusses) — indeed Glaser is one of Nelkin's own cited references, and Nelkin's belted-brief architecture is a direct development of it. Both address the identical problem: keeping reducing pressure on an abdominal hernia while the garment remains wearable as underwear.

2. The art recognized and addressed the exact problem the claim solves. FLA '719's background — part of the same prior-art record — expressly faults Nelkin because the encircling belt "forms in effect a second waistband which tends to cause discomfort while … providing a limited … degree of hernia retaining support adjustability," and it replaces the belt with side-anchored straps. That is evidence that the field was actively searching for a better anchor location for the second band. Glaser supplies the alternative the field was looking for: anchoring the band at the rear so the front is the free, adjustable end.

3. Simple, predictable mechanical reversal of fixed and free ends. Nelkin's own disclosure makes the substitution trivial: Nelkin states the belt is "secured to the brief only at the front portion … whereby the portion of the belt at the back … can be moved up and down." Reversing which end is sewn and which end is free is a change in a known mechanism that produces the same known result — the un-anchored portion is the adjustable portion. In re Harza; KSR ("a court must ask whether the improvement is more than the predictable use of prior art elements according to their established functions").

4. Finite, enumerated, predictable alternatives. The attachment point for an abdominal band is one of three: front (Nelkin), back (Glaser), or sides/hip-forward (FLA '719). Each has a known, predictable trade-off: whichever end is anchored, the opposite end is the adjustable end. Where "a finite number of identified, predictable solutions" exists, KSR makes the choice obvious. Selecting the back anchor is further compelled here because the patent itself says abdominal hernias are at the front ("as that is where abdominal hernias are likely to be present, not at the back"), so the artisan seeking front adjustability is led directly to a rear anchor.

5. Anchor-on-the-small-of-the-back is dictated by the anatomy Nelkin already targets. Nelkin is directed at hernia relief; the natural band path that resists slip-down on a protuberant abdomen is the shortest circumference path — a geometric fact, not an invention. Optimizing placement along a result-effective variable does not confer patentability. In re Applied Materials, Inc., 692 F.3d 1289, 1295 (Fed. Cir. 2012).

6. No unpredictable interaction. Each element performs the identical function it was known to perform: spandex panels apply inward pressure; the hole externalizes the genitals; the belt applies focused abdominal pressure; the sewn waistband anchors the assembly. The combination is the paradigm KSR case of "arrang[ing] old elements with each performing the same function it had been known to perform … yield[ing] no more than one would expect from such an arrangement."

Ground 2 (alternative base): Glaser '103 in view of Nelkin '272 / FLA '719, plus Thrower '495

Glaser supplies: the abdominal band fixed at the rear only (§1(d)); the externalizing genital opening (§1(b)); a garment with front, rear and crotch sections. Nelkin/FLA supply: spandex elastic panels in place of Glaser's expressly "non-elastic fabric" (§1(a)); a sewn elastic waistband (§1(a)); and hernia-covering band width (§1(d)). Motivation: Glaser's own stated object is to "prevent abdominal and/or inguinal hernias from bulging," and its non-elastic, multi-layer fabric is uncomfortable and provides no conforming pressure; substituting the spandex brief of Nelkin/FLA — the very fabric the field had adopted for this purpose — is the obvious materials substitution with a predictable improvement (inward elastic pressure and conformity) and no change in function. In re Kemps; KSR.

Ground 3: FLA '719 in view of Glaser '103 and Thrower '495

FLA '719 supplies the spandex brief with front/side/rear panels joined to an elastic waistband and abdominal truss pads. Glaser supplies the rear-anchored adjustable band (FLA '719's own stated objection to Nelkin's belt — that it forms a second waistband — is answered by Glaser's rear anchor, which lets the front adjust while the band pivots at a single fixed point). Thrower supplies the vertically-oriented oval opening with the wider portion up. Motivation: FLA '719 is expressly a comfort-and-adjustability improvement over Nelkin; Glaser and Thrower are the two known mechanisms for (i) adjustable abdominal banding and (ii) genital decompression, so the artisan seeking to make a spandex hernia brief comfortable across the abdomen and genitals is directed to exactly these two references.

Claim 1 — conclusion

Claim 1 is obvious under pre-AIA § 103(a) over Nelkin + Glaser (+ Thrower and/or Lerman). Each element is disclosed, the references are analogous art in a single recognized field, and the field itself identified the attachment-location problem and had already produced the claimed solution (Glaser) years before the priority date.

5. Claims 2 and 3

Claim 3 (independent)

Adds (i) the brief being "close fitting … adapted to be worn by a human male"; (ii) the panels extending up to the waistband, the waistband being "a continuous unbroken loop sewn to the upper edges of said elastic panels"; (iii) the lower arc of the hole "oriented downward toward the perineal panel"; (iv) the band being "pivotally attached"; and (v) the same undershirt element as claim 2.

• (i)–(iii) are disclosed or obvious per §4 (Nelkin's band 18 is a waist-encircling loop sewn all around; FLA '719 recites panel upper edges "attached to an elastic waistband"; Thrower teaches the wider-portion-up orientation, which necessarily places the narrower arc at the bottom).
• (iv) "Pivotally attached" is not an added structure — it is the inherent mechanical consequence of anchoring one end of an elastic band and leaving the rest free. The applicant's own spec confirms this is nothing more than edge-to-edge sewing (FIG. 8a). Inherency defeats the limitation. Best.
• (v) See claim 2.

Claim 2 (dependent) and claim 3's undershirt element

The element is: an undershirt with shoulder straps, its torso-portion lower edge sewn to the waistband, "continuous along the entire top edge of said waistband."

• Linneros US 1,263,576 (cited) discloses a shorts-plus-undershirt combination with shoulder straps. The applicant's distinction — that Linneros buttons rather than sews — is addressed by Nelkin and FLA, both of which teach that undergarment components are sewn ("attached to the fabric of the brief 2 as by sewing"; panels "attached to an elastic waistband"). Substituting a permanent sewn seam for a buttoned attachment is the most routine of garment-design choices and is expressly suggested by Nelkin's own disclosure that the brief's waistband is sewn.
• Sanders US 1,339,070 ("Combination-undergarment"), Peters US 898,258 ("Suspensory undershirt") and Firsching US 2,601,602 ("Undergarment for men") establish that joining a shirt portion to a lower garment with supportive shoulder straps is a century-old, thoroughly conventional construction (the union suit).
• Motivation, drawn from the applicant's own words and from common sense: shoulder straps "convey additional lift to the waistbands and lower abdominal portion, especially if there is a hanging pouch of fat"; attaching the shirt to the waistband "prevents the waistband from folding, which would result in pinching and binding" and "prevents the undershirt from creeping upward on the torso." These are precisely the predictable benefits of sewing a shirt to a supporting waistband. A continuous seam "along the entire top edge" is a design choice with no asserted criticality — the spec itself prefers only "at least at the front half," undermining any argument that continuity is inventive.

6. The weakest links in the § 103 case (where an applicant could push back)

Intellectual honesty requires flagging these:

1. The sloped, high-back/low-front waistband path (§ 1(a)). This is the one element I could not map to a specific cited reference. Glaser's "slightly concave" front upper edge is thin. If this element were treated as the point of novelty, the Office would want additional art. Such art almost certainly exists — the high-back/low-front waistband is standard in maternity support garments, abdominal binders, and back-support belts, none of which the examiner appears to have cited. A search of A61F5/24, A41B9/14 and A61F5/03 (corsets/abdominal supports) subclasses in that era should locate it. This is the single most productive gap to fill if the validity of these claims is material.

2. "Sewn to said waistband at the back only" — Glaser attaches to the rear section, not to a waistband. Glaser's garment arguably lacks a discrete elastic waistband. A challenger should pair Glaser with Nelkin (or FLA) expressly to supply the waistband and argue that attaching a band to the rear of a garment having an elastic waistband would, by design choice, be to the waistband itself. This is a solid but not airtight argument.

3. Relative-radius limitation. Claim 1 requires only that the upper arc radius exceed the lower. Lerman's ovoid shape and Thrower's "wider portion being vertical" cover that. But if applicant amended to the specific ¾″/½″ radii or the 2½–3½″ hole length from the spec, those ranges are not in the claims and, if added, would present a new obviousness question (though ranges with no disclosed criticality are weak nonobviousness positions — In re Woodruff, 919 F.2d 1575 (Fed. Cir. 1990)).

4. Functional pressure language. Applicant may argue the references don't disclose the pressure differential. The answer is inherency plus the fact that Glaser/Thrower's externalizing openings by design remove the scrotum and penis from the garment's pressure envelope.

7. Likely applicant rebuttals, and why they are weak

8. Diligence flags that interact with the § 103 analysis

1. Priority / written-description risk. The 2004-06-16 provisional (60/580,115) is titled "Garment for Enhancing Male Sexual Performance"; the 2005 application 11/147,693 carries the same title. Only the 2009-02-05 application 12/322,648 carries the hernia title. If the hernia-compression claims are not supported by the 2004 provisional — a real question on these facts — the effective filing date for § 102/§ 103 purposes could move to 2009-02-05 or later. That would:
   • not disturb Nelkin, Glaser, Thrower, Lerman or Linneros (all pre-2004);
   • pull in intervening art published/filed 2004–2009, including e.g. US 2008/0086105 A1 ("Protective underwear with abdominal support," published 2008-04-10), which discloses an elastomeric abdominal support member extending over the abdomen of an undergarment, and US 2012/0172780 A1 (Quinn, "Scrotal support garment," priority 2008-02-27), which appears in this patent's own "Cited By" list. Whether those are prior art depends entirely on the priority determination.
2. Prosecution history has not been reviewed here. I have not examined the file wrapper. Given that the specification is unusually argumentative about Nelkin ("the Nelkin secondary band (4) is fastened to the garment at the front, not the back as is the present invention"), it is highly likely the applicant traversed Nelkin and Glaser on the front/back anchor point. The file wrapper will show which references were applied and how; that record is essential to any validity opinion.
3. No validity testing has occurred. Consistent with the prior sections of this analysis, no litigation, PTAB proceeding, or reexamination of US 8,615,815 appears in the public record, so the claims have never been tested adversarially.
4. Verify the uncited Group E references myself. My retrieval of US 6,868,850 (Takenaga, "Hernial truss"), US 2,593,262 (Calabrese) and US 3,037,503 (Ravaschieri) was cut off. Those three in particular could add independent § 102/§ 103 grounds, and the first is a truss patent from the same era as FLA '719.

9. Bottom line
