Union Water-Meter Company v. Henry A. Desper

I'll research this case thoroughly. Let me start with several searches.

Let me get the full opinion text and details on the patents involved.

Let me verify the procedural history, counsel, and doctrinal significance.

Case Overview and Background

Parties. The plaintiff/appellant, the Union Water-Meter Company, was the assignee and operating owner of the Ball & Fitts water-meter patent portfolio; it took the reissue at issue (granted March 24, 1874) as assignee and used it to protect its meter business — i.e., a classic nineteenth-century operating company that made and sold the patented device, not a non-practicing entity (the NPE/PAE, IPR, RPX-type framework simply did not exist in 1879). The defendant, Henry A. Desper, was a competitor inventor and meter manufacturer who held his own U.S. Patent No. 144,747 (Nov. 18, 1873, "improvement in fluid meters"), and the answer alleged that "all water-meters made by the defendants are constructed according to letters-patent No. 144,747 … except in the omission of a certain adjusting screw" (the opinion refers to "defendants" plural, with Desper "one of the defendants"). So this is direct, competitor-versus-competitor infringement litigation. Counsel were Mr. Andrew McCallum for the appellant and Mr. J. E. Maynadier for Desper. (101 U.S. 332 opinion text, Justia; CourtListener)

Patents and accused technology. The asserted right is Reissue No. 5,806 (opinion text; some syllabi misprint "5808"), reissuing U.S. Patent No. 109,372, granted Nov. 22, 1870 to Phinehas Ball and Benaiah Fitts for "improvements in water-meters." The patent covers no separate part of the meter — only a combination, claimed in reissue Claim 4, whose five elements are: (1) a rotary valve g with ports; (2) two cylinders b, b′; (3) double-acting pistons c, c′ on rods d with a single cam-slot e; (4) adjusting stops o for setting stroke length; and (5) a crank-shaft i, with pinion and cranks, transmitting motion from the pistons to the valve. The patent's own backdrop included an earlier Ball & Fitts patent (July 20, 1869) and an 1851 Ericsson water-meter patent. The accused meter used a rotary valve (without the bevel-gear), two cylinders (set at right angles rather than parallel), double-acting pistons, and fixed (not adjustable) Ericsson-type stops — but it had no crank-shaft at all: the valve was driven directly by a single crank keyed to the valve stem whose pin rode in the slots of the crossed piston-rods. (U.S. Reports, 101 U.S. 332, LOC PDF; Justia)

Posture, venue, and holding. The suit was a bill in equity in the U.S. Circuit Court for the District of Massachusetts (the federal trial court of that era), which ruled for Desper; the Union Water-Meter Company appealed to the Supreme Court, which decided at October Term 1879 (decision dated Oct. 1, 1879), 101 U.S. 332, 25 L.Ed. 1024, opinion by Justice Bradley. The Court reversed the circuit court's decree and directed dismissal of the bill with costs — i.e., no infringement. The venue was the natural one: it was the parties' commercial situs and the place of Desper's manufacture. No judge, division, or PACER-style docket detail is reported in the published opinion, and PTAB/IPR, Law360, and RPX concepts are anachronistic here. (vlex citation data, 25 L.Ed. 1024; Justia)

Why it is notable, and a sourcing caveat. Water-Meter Co. v. Desper is a foundational statement of the "all-elements" rule for combination claims: the Court held that a combination claim "is not infringed if any of the material parts of the combination are omitted," and that infringement lies only where an omitted part is "only formally omitted[] and is supplied by a mechanical equivalent, performing the same office and producing the same result." Critically, it held that "the courts in this country cannot declare that any one of the elements entering into such a combination is immaterial" — they may only ask whether the omitted element was replaced by an equivalent. Applying that rule, the accused meter's elimination of the crank-shaft assembly (and its substitution of fixed stops for the claimed adjusting stops) defeated infringement. The case remains cited in the modern equivalents/all-elements line of authority flowing through Warner-Jenkinson Co. v. Hilton Davis Chemical Co., 520 U.S. 17 (1997), and it reflects the era's market context — rapid build-out of

I'll research this 19th-century case carefully. Note at the outset that most of the modern procedural categories requested (IPR/PGR, Markman, JMOL, PACER) did not exist in 1879 — I'll map them to their historical analogs and flag the anachronisms explicitly.

Now let me find the lower court (Circuit Court) proceedings, counsel details, and the patent's prosecution/reissue history.

Let me look for the circuit court proceedings, the reissue history, counsel, and any related litigation.

Important framing caveat (read first)

This is an 1879 equity case from the U.S. Circuit Court for the District of Massachusetts, affirmed by the Supreme Court at the October Term 1879. Several of the procedural categories you asked about did not exist and cannot be sourced:

• No PACER / no docket number. Federal dockets and PACER begin in 1988–1990. No CM/ECF docket, and no modern-style docket number, exists for this case. (One aggregator renders the "Docket Number" as "WATER-METER," which is simply the reporter's shorthand, not a real docket entry.)
• No PTAB, no IPR/PGR/CBM. The Patent Trial and Appeal Board and AIA post-grant proceedings date from 2012. In 1879, the only administrative patent challenges were ex parte reissue and interference practice in the Patent Office.
• No Markman hearing, no JMOL, no Rule 12/56 motions, no Rule 54(d)/§285 fee practice. The Federal Rules of Civil Procedure date from 1938; Markman from 1996; the Federal Circuit from 1982. In 1879 patent cases were bills in equity tried to the judge, with appeals going directly to the Supreme Court.

Below I map your requested categories onto their 19th-century analogs, and I flag where the record is not well sourced.

Chronological development

1. The patents and reissue (pre-suit): 1869 → 1874

• 1869-07-20 — Ball & Fitts obtain an earlier patent covering the rotary valve and the combination of cylinders, piston rods, crank-shaft and rotary valve. This earlier patent becomes central to the defense.
• 1870-11-22 — Original US Patent 109,372 issued to Phinehas Ball and Benaiah Fitts for "certain improvements in water-meters."
• 1873-11-18 — US Patent 144,747 issued to Henry A. Desper (defendant) for "an improvement in fluid meters" — the basis on which Desper claimed his meters were built.
• 1874-03-24 — Reissue RE 5,806 granted to the Union Water-Meter Company as assignee of Ball & Fitts. Claim 4 of the reissue is the asserted claim. (Note: the printed Syllabus in some reprints misstates the reissue as "No. 5808"; the opinion text and the case metadata both say 5806 — a known reporter's misprint.)
• Counsel of record: Andrew McCallum for the appellant (Union Water-Meter Co.); J. E. Maynadier for Desper. (Sourced to the reporter's headnote; I could not independently verify their full firm affiliations.)

2. Filing & initial pleadings (Circuit Court, D. Mass.) — ca. 1874–1877

• Complaint (bill in equity): Union Water-Meter filed a bill in equity against Henry A. Desper and others to restrain infringement of RE 5,806 and for an account of profits and damages. (Not a "complaint" with numbered counts in the modern sense.)
• Answer (the pleading analog to an answer/counterclaim): Per the Supreme Court's recitation, the defendants' answer:
  • denied that the reissue was for the same invention as the original;
  • averred the invention was already covered by Ball & Fitts' 1869-07-20 patent;
  • denied the patentees were the first and original inventors, citing older patents and prior public knowledge/use;
  • denied infringement; and
  • averred that all their meters were made under Desper's US 144,747, "except in the omission of a certain adjusting screw."
• There were multiple defendants ("Henry A. Desper, one of the defendants"), though the case is captioned against Desper alone.
• No counterclaim in the modern sense — inequitable-conduct/invalidity contentions were raised as equitable defenses within the answer, not as separate affirmative claims for relief.
• Not sourced: the exact filing date of the bill, the names of the co-defendants, and the ad damnum.

3. Pre-trial motions of substance

• No Rule 12 motion to dismiss, no transfer motion, no stay pending IPR, and no summary judgment are documented — none of these mechanisms existed in equity practice. The functional equivalents (a demurrer or a plea to the bill, or a motion to dismiss for want of equity) may have been used, but I found no record of any such filing, and I will not fabricate one.
• The substantive pre-trial battleground was evidently the scope and validity of the reissue and claim construction of Claim 4, resolved by the court rather than by dispositive motion.

4. Claim construction (the Markman-analog) — the core legal development

The Supreme Court's opinion (by Justice Bradley) is, in substance, a claim-construction ruling, and it produced the case's enduring holdings:

• The Court parsed Claim 4 as a five-element combination claim:
  1. the rotary valve;
  2. the two cylinders;
  3. the double-acting pistons connected by a rod with a cam-slot at right angles to the rod;
  4. the adjusting stops; and
  5. the crank-shaft with its pinion and cranks transmitting motion from pistons to valve.
• The only elements arguably new over the 1869 Ball & Fitts patent were the adjusting stops and the rectangular slot orientation — so the reissue "occupies very narrow ground."
• Two settled rules applied: a combination claim is not infringed if a material part is omitted; but it is infringed if the omitted part is supplied by a mechanical equivalent performing the same office and producing the same result.
• Critically, the Court held that U.S. courts cannot declare any claimed element "immaterial" where the patentee has claimed a specific combination: "The patentee makes them all material by the restricted form of his claim." The Court expressly declined to follow the broader English practice of treating elements as immaterial. This is the ancestor of the modern all-elements rule.

5. Discovery milestones

• Not well sourced. Equity practice in 1874–1879 permitted interrogatories, discovery, and testimony taken before an examiner or master, but I found no record of specific discovery events, depositions, exhibits, or a master's report. I will not invent them. The accused structure is described in enough mechanical detail in the opinion that an inspection/comparison of the meters plainly occurred, but the procedural vehicle is undocumented in what I retrieved.

6. Trial / decision in the Circuit Court

• Patent equity cases of this era were tried to the court without a jury; there was no verdict.
• The Circuit Court dismissed the bill / entered decree for the defendants on the merits. Union Water-Meter appealed.
• Not sourced: the Circuit Judge's name, the hearing dates, and any written opinion. I could not retrieve a separate reported Circuit Court opinion in the Federal Cases reporter. If one exists, I have not verified it.

7. Supreme Court appeal — the decisive ruling

• Posture: Appeal from the Circuit Court for the District of Massachusetts (equity appeals went directly to the Supreme Court; there was no intermediate appellate court for patent cases in 1879).
• Argued by: Andrew McCallum (appellant) and J. E. Maynadier (appellee).
• Decision: Opinion by Justice Bradley, October Term 1879, reported at 101 U.S. 332, 25 L.Ed. 1024, conventionally cited as 1879 (some databases render it 1880; the exact day of decision is not reliably sourced — the case metadata lists a termination date of 1879-10-01).
• Substance of the ruling on infringement (rejecting the patentee's theory):
  • Desper's meter used a rotary valve (without bevel gear), two cylinders (at right angles rather than parallel), double-acting pistons, and Ericsson's stops — but fixed, not adjustable.
  • Decisively, Desper's meter had no crank-shaft and no semblance of one; the rotary valve was driven directly by a single crank keyed to the valve stem, engaging slots in the piston rods. The crank-shaft "with all its appurtenances, is thrown out of their machine." The "crank" used was part of the valve itself, and the crank as a motion-converting device was old (steam engines a century earlier).
  • Because the crank-shaft was a material element of the claimed combination and no equivalent was substituted, there was no infringement.
• Disposition: "Decree affirmed" — judgment for the defendants, i.e., for Desper.

8. Post-trial motions (JMOL / new trial / fees)

• Not applicable. No jury meant no JMOL and no motion for new trial in the modern sense, and there was no Rule 54(d)/§285 fee practice. Whatever costs the decree carried are not sourced in what I retrieved. The case ended with the Supreme Court's affirmance.

9. Settlement / dismissal / final disposition / posture

• No settlement is reported.
• Final disposition: Supreme Court affirmed the Circuit Court's decree for the defendants; the reissue was held not infringed. There was no holding of invalidity — the Court assumed the reissue's validity arguendo and decided the case on non-infringement.
• The case is terminated (metadata termination date 1879-10-01), with no further appellate or administrative activity.

10. Parallel post-grant / administrative proceedings

• No PTAB IPR/PGR (mechanism did not exist until 2012).
• The only administrative dimension was the ex parte reissue itself (RE 5,806, granted 1874-03-24), which reshaped the original US 109,372 claims — including the addition of the adjusting stops element that the defense later argued was not supported for the reissue, and, more importantly, the restricted combination form that lost the case. The defendants also invoked the same inventors' prior 1869-07-20 patent as anticipating/covering the invention.
• The case law of this era was cited for the proposition that a reissue cannot broaden a claim beyond the original invention — a doctrine the Court's "narrow ground" reasoning reinforced without squarely deciding.

Bottom line

I'll research this 19th-century case. Note upfront that PACER, Law360, and Reuters Legal have no coverage of an 1879 case, so I'll work from the U.S. Reports, the Lawyers' Edition, and historical sources.

I have the core answer from the U.S. Reports. Now let me research the attorneys and the lower court proceedings.

Bottom line

For this 1879 case there is no PACER docket, no Law360 or Reuters coverage, and no firm-website trail — the case predates all of it, and the Supreme Court did not publish attorneyFirm or "of counsel" designations in that era. What exists is the official reporter's counsel line.

The only plaintiff-side counsel named anywhere in the official record is Andrew McCallum. The full counsel entry in the case is two lines:

"Mr. Andrew McCallum for the appellant. — Mr. J. E. Maynadier, contra."
— Water–Meter Co. v. Desper, 101 U.S. 332 (Oct. Term 1879); also reported at 25 L.Ed. 1024.

Sources: U.S. Reports text (Library of Congress / law.resource.org); CourtListener 90131; Cornell LII. The reporter text (including the counsel line) is identical across all three — the U.S. Reports "headmatter" is the authoritative source here.

Counsel for the plaintiff (Union Water-Meter Company, appellant)

Confidence note on the identification: the obituary/biographical sketch matches the right person on time, place, and profession (Boston patent lawyer, 1878–1880). It is a strong but circumstantial identification — I found no document that expressly ties this McCallum to the Union Water-Meter appeal, and no middle initial is given in the reporter, so I cannot rule out a namesake. I did not find a Supreme Court bar admission record or a counsel-of-record filing for him in this case.

Explicit gaps — do not assume these exist

• No firm affiliation, office address, or "lead/of counsel/local counsel/in-house" label for McCallum is recoverable. The 1870s U.S. Reports format simply states "for the appellant." Any such label would be inference, not record.
• No additional plaintiff-side counsel appear in the reported case. In 19th-century Supreme Court practice, out-of-town counsel frequently associated a Washington attorney, but no such name appears in this report, and I could not verify one. I will not invent one.
• The Circuit Court stage is not documented in what I could retrieve. I could not locate the C.C.D. Mass. opinion or its appearance/order sheet to confirm who signed the bill and who tried the case below. The Supreme Court opinion (via Bradley, J.) recites only that it was a bill in equity by the Union Water-Meter Company as assignee of Reissue No. 5,806 (reissue of No. 109,372, granted to Phinehas Ball and Benaiah Fitts, reissued to complainant 24 March 1874), against Henry A. Desper and others, who answered that their meters practiced Desper's own Patent No. 144,747 (18 Nov. 1873) "except in the omission of a certain adjusting screw."
• Nothing is sealed. This is a public 1879 equity case; the absence of counsel detail is an artifact of era and record-keeping, not sealing.

Defense side (context only)

J. E. Maynadier appeared "contra" for Desper. I could not confirm his given names, firm, or office from a reliable source; a "Maynadier" appears in Maryland reports (Maynadier v. Armstrong, 98 Md. 175), but I found no basis to connect that family to this Boston patent case, so I am not attributing it.

Where the "docket sheet" analog lives

If you need a counsel-of-record roster beyond the reporter's line, the archival equivalents are at the National Archives (Record Group 267): the Supreme Court's Engrossed Dockets and Journal for the October Term 1879 (which record the filing of the transcript of record and the appearance of counsel), and the original appellate case file for Water-Meter Co. v. Desper containing the parties' printed briefs — the briefs, not the opinion, are where additional associated counsel would be named. The transcript of record would also carry the Circuit Court appearance entries. These are not online, so any such names would have to be confirmed by a pull from NARA or a visit to the Supreme Court library.

Net answer to your question: one attorney — Andrew McCallum — for the Union Water-Meter Company, as appellant; Boston-based patent lawyer and (from 1878) general counsel of the Eastern Railroad Association; no firm name or formal role designation is of record.

I'll research this 19th-century case. Let me start with searches on the Supreme Court opinion and its reported counsel.

Key finding: the reported counsel on the defense side was Mr. J. E. Maynadier. Let me dig into who he was and search for the lower-court (Massachusetts Circuit) counsel.

Counsel of Record for the Defendant — Sourcing and Constraints

Before giving names, one important caveat that the case's age forces on us:

• PACER, Law360, and Reuters Legal cannot help here. They did not exist in 1879 and PACER's electronic docket coverage begins in the late 20th century. There is no modern docket sheet for this case, and no sealed filings to report. The only authentic "counsel of record" source for a case of this vintage is the reported opinion itself (the U.S. Reports headnote/argument line) and contemporaneous reporter volumes (e.g., Banning & Arden's Patent Cases, the Federal Cases series).
• The case was appealed to the Supreme Court from the U.S. Circuit Court for the District of Massachusetts. I located the Supreme Court-side counsel but could not locate a named counsel of record for the circuit-court (trial) stage in the sources searched. I will say so explicitly rather than guess.

Defendant's Counsel of Record

1. J. E. Maynadier — Counsel for the Respondent (Defendant Henry A. Desper) in the Supreme Court

• Name / Role: "Mr. J. E. Maynadier, contra" — i.e., counsel for the appellee/respondent, the defendant Henry A. Desper, on the appeal to the U.S. Supreme Court. This is the only defense-side attorney of record I can authenticate for this case. He is listed directly opposite the plaintiff's counsel in the reported argument line.
• Source: Water-Meter Co. v. Desper, 101 U.S. 332, 25 L.Ed. 1024 (1879) (opinion by Justice Bradley), which carries the headnote line: "Mr. Andrew McCallum for the appellant. Mr. J. E. Maynadier, contra." (Corroborated across Cornell LII, Justia, Wikisource, OpenJurist, and CETIENT reproductions of the official report.)
• Firm and office location: Not established by any source I found. I could not confirm a firm name or office for Maynadier from the searched materials. He appears to have been a patent-law practitioner of the era (see the experience note below), but I will not attribute a specific Washington or Boston firm to him without a source.
• Relevant patent experience (partial, and flagged as uncertain): A "Maynadier" surfaces in contemporaneous patent litigation — e.g., Maynadier v. Tenney, 16 F. Cas. 1258, 2 Ban. & A. 615 (C.C.D. Mass. 1877) (a shoe-sole die-cutter patent case applying the same "omitted element / mechanical equivalent" doctrine later used in Desper; in which "J. E. Maynadier" appears as counsel per a contemporaneous reporter excerpt), and a search snippet shows "J. E. Maynadier, for defendant" in a Patent Office/Supreme Court reporter volume. Note: the case-name pattern in Maynadier v. Tenney and the presence of a "Maynadier" as party in the same district/era creates ambiguity about whether this is the same individual as counsel; treat his broader practice record as unverified. I also could not confirm his full given name or Patent Office service, so I am not asserting it.

That is the entirety of the verifiable defense-side record. For completeness on who is not defense counsel:

• Mr. Andrew McCallum — counsel for the appellant/plaintiff (Union Water-Meter Company), not the defendant. Do not list him for Desper.

---

What I Could Not Establish (stated explicitly, per your instruction)

1. Trial-level (Massachusetts Circuit Court) counsel for Desper. No counsel of record for the lower-court equity proceeding could be located in the sources searched. The reported opinion recites only the Supreme Court argument line.
2. Additional defense counsel. The opinion repeatedly refers to "the defendants" (plural) and describes Desper only as "one of the defendants." If multiple defendants appeared, no separate counsel for co-defendants is recorded in the sources searched.
3. Any firm affiliation, office, or in-house designation for Maynadier — none confirmed.
4. Any "local counsel" (Massachusetts-admitted) vs. Supreme Court bar distinction — the 1870s Supreme Court bar rolls did not distinguish local counsel the way modern practice does in the sources available to me, and no such split is reported.

If you want to try to close the trial-court gap, the productive next sources would be the Circuit Court for the District of Massachusetts equity docket/order books (NARA–Boston, Record Group 21) and Banning & Arden's Patent Cases volumes, which often print the full counsel appearances for the trial court — neither of which is searchable via the tools used here.

Bottom line: The single well-sourced attorney representing the defendant in this case is J. E. Maynadier, counsel for the respondent in the Supreme Court (Water-Meter Co. v. Desper, 101 U.S. 332 (1879)). His firm/office and any trial-court co-counsel are not documented in the sources searched.
