Jeffrey A. Roberts — the houseboat hull. U.S. Patent 3,870,005, "Houseboat hull," filed December 12, 1973, granted 1975, assignee not stated on the face as reached. The face prints the residence this section requires: "Jeffrey A. Roberts, 55135 Belair, Osceola, Ind. 46561," co-inventor with Richard E. Klingler of Elkhart — Klingler's share is Elkhart's and is not claimed here. What the patent claimed: a houseboat hull of "reverse cathedral" configuration — two spaced, substantially similar V-shaped outer bottom members and a central V-shaped bottom member between them, the central member's draft less than the outer members'. It is the ground's one recreational-industry patent and its earliest face-proven grant of the modern record.
Sham Yuen Chan — the Miles biochemist. Two granted European patents carry his residence on their faces: "Chan, Sham Y. — 11435 Birchtree Drive, Osceola Indiana 46561 (US)," proprietor Miles Inc. of Elkhart. EP 0 158 958 B1, "Method and cell line for obtaining plasminogen activators" (U.S. priority application 601,868, filed April 19, 1984; European grant published April 24, 1991) — a method of increasing the yield of plasminogen activator, the clot-dissolving protein class behind tPA therapeutics, from a producing cell line, and the cell line itself. EP 0 254 076 B1, "Improved recombinant protein production" (U.S. priority filed July 11, 1986; grant published May 8, 1991) — improvements to recombinant protein manufacture in cultured cells. Chan's later Bayer patents in the factor VIII line (U.S. 5,952,198; 6,180,108; 6,358,703, 1999–2002) are not claimed for this ground: no Osceola residence for him was found on their faces as reached, and by that era his published addresses stand elsewhere. The claim here is exactly two patents deep and face-proven.
Steven C. Charlton — the ion assay, claimed at application strength. EP 0 475 045 A1, "Method and device for the assay of ions" (U.S. priority application 564,050, filed August 6, 1990; European application published March 18, 1992), applicant Miles Inc., prints "Inventor: Charlton, Steven C. — 10275 Douglas Road, Osceola, IN 46561 (US)": a test device for determining the presence or concentration of a medically interesting ion — sodium, potassium, calcium, magnesium, lithium — in an aqueous sample. The discipline prints with the entry: the document reached is an application publication, not a granted face, and Charlton's granted ion-test patent, U.S. 4,649,123, "Ion test means having a hydrophilic carrier matrix" (March 10, 1987, Miles Laboratories), does not seat him at Osceola on the face as reached. The same man's test-device patents of 1986–87 print an Elkhart address for him. Residence is taken patent by patent, so this ground claims the 1990 application face and no more of Charlton.
Mary Ellen Warchal, later Warchal-Windham — the test-device chemist. Her fuller article stands at row #303; the patent-by-patent line belongs here. The European faces print "Warchal, Mary Ellen — 10272 Jefferson Road, Osceola Indiana 46561 (US)" as co-inventor, with James P. Albarella, Steven C. Charlton, and James W. Reinsch of Elkhart, proprietor Miles Inc., on EP 0 239 926 B1, "Rainbow test device" (granted June 23, 1993), and EP 0 240 849 B1, "Controlled hue test device" (granted November 24, 1993) — test compositions that generate different, controlled hues at different analyte concentrations, the rainbow device producing the hues of a full spectrum for glucose in body fluid. The family's U.S. grant is U.S. 4,898,813, "Catalytic test composition intended to produce a range of colors" (Albarella et al., February 6, 1990, filed April 4, 1986). A decade and a half later her granted U.S. face still seats her here: U.S. 7,163,616 B2 (January 16, 2007, Bayer Corporation) prints "Mary Ellen Warchal-Windham, Osceola, IN (US)" among the inventors of reagent and electrochemical-sensor technology for detecting analytes.
Ralph Hernicz — the reflectance standard, at application strength. EP 0 184 097 A2, "Reflectance standard" (U.S. priority application 678,120, filed December 4, 1984; European application published June 11, 1986), applicant Miles Laboratories, Inc., prints "Inventor: Hernicz, Ralph — 54427 Faye Drive, Osceola Indiana 46561 (US)": a reflectance standard for the optical instruments that read test devices, made by incorporating at least 40 percent by weight of barium sulphate into an acrylate polymer, achieving about 90 percent or better reflectance across the near-UV and visible range. Application-stage in the record reached; no granted face for it was found, and it is carried at that strength.
Joseph E. Perry — the centrifuge power supply. EP 0 320 737 B1, "Slow start power supply" (U.S. priority application 141,065, filed December 18, 1987; European grant published September 29, 1993), proprietor Miles Inc., prints "Inventor: Perry, Joseph E. — 58075 Potawatomi Drive, Osceola Indiana 46561 (US)": a motor-control circuit that brings a centrifuge — in context, a blood-component separator — up to speed gradually and holds its rotational speed and spin time precisely, so cellular components separate from plasma without disruption. Granted in Europe; the U.S. grant of the priority application was not separately verified and is not separately claimed.
Gerald R. Stanley — the amplifier engineer. Carried whole at row #299; the face line here: U.S. 6,504,348 B2, "Remote sensing by high-order filtering" (January 7, 2003), and U.S. 8,401,207 B2, "Motional feedback system" (March 19, 2013), both print "(75) Inventor: Gerald R. Stanley, Osceola, IN (US)," assignee Harman International; the European face of his high-efficiency amplifier family, EP 2 395 656 B1, prints "Stanley, Gerald R. — Osceola, Indiana 46561 (US)" (the family's U.S. member is U.S. 7,557,622, 2009).
The names tested and not entered: James Oliver's forty-five plow patents are South Bend's (Notable People's ground and the South Bend build's); James B. Jarmin's automatic corn-planter (U.S. 640,205, 1900) belongs to Osceola, Nebraska, and is the search's standing wrong-state trap; the five patents of the late Craig Reske are a Niles, Michigan man's, surfaced only because an aunt lives here; and no nineteenth-century patent face naming an inventor "of Osceola" in St. Joseph County was returned by any search — the early ground's inventive record is Young's unpatented one, at row #301. Closure: DUG — seven inventors carried patent by patent with dates, claims, and face-printed residences; application-stage documents and cross-residence cases labelled as such, never promoted.
