  • US 5,293,857 "Hydrogen gas fuel and management system for an internal combustion engine utilizing hydrogen gas fuel". Filed 2 Nov 1990, granted 15 Mar 1994. It is the US member of the WO 92/08046 family. The PDF was downloaded to research/files/US5293857.pdf (17 pp.). The Birth brief lists it, but the folder lacks it. Needs a deep read.
  • JPH03500042A: Japanese member of the US 5,149,407 / WO 89/12704 family, priority 16 Jun 1988.
  • AU3862389A: Australian member of the same family (abandoned).

  • AU6887091A: Australian member of the WO 92/08046 family.
  • EP0333854A1 (the folder holds only the A4 search report). Withdrawn: "deemed to be withdrawn" 2 Mar 1993.
  • DE3280356D1 and DE3280143D1: German members of the EP 0 111 574 / EP 0 101 761 families.
  • These are NOT Meyer patents, despite appearing in the "family/related" lists: EP0558592B1 (C.P. Moore), DE68915764T2 (Dijkhuis, cold fusion), DE69124882T2 (Kaufman).
  • US 5,293,857, US 5,149,407 and US 4,936,961 each record the same assignment, dated 22 Mar 2001: from "MEYER, STANLEY A., ESTATE; CINCIONE, ALPHONSE P., ADMINISTRATOR OF THE ESTATE OF" to MEYER, MARILYN, OHIO.
  • US 4,936,961: fees paid 1993, 1998 (late) and 2002 (late); expired at the end of its term (anticipated expiry 2007-08-05).
  • US 5,149,407 lapsed for non-payment on 22 Sep 2004.
  • US 5,293,857 lapsed on 15 Mar 2006.
  • CA 2,067,735 (Water Fuel Injection System): examination request on 15 May 1998, eight weeks after Meyer's death. That fits the probate entry of 8 May 1998 approving maintenance of "the patents in Canada" (see the stanslegacy note). Status "Dead" on 28 Nov 2003.
  • Pattern: the estate and the widow kept some patents in force until 2002 and then let them lapse. Marilyn Meyer died on 29 Jul 2003 (per stanslegacy).
  • US 5,632,870 (Yan R. Kucherov, "Energy generation apparatus", priority 13 May 1994, granted 27 May 1997) cites Meyer's patents. The abstract describes an electrolytic cell that captures environmental heat at the anode "transferring thermal energy from the anode to the ions". It is a later patent claiming that ambient heat supplies part of the energy needed to split water. Not read in full.
  • Citation counts on Google Patents: US 4,936,961 is cited by 59 later documents, US 5,293,857 by 51, US 5,149,407 by 25. These later documents are a pool of related work.
