Queries / pages: US20060163971A1; US7830065B2; US8093869B1; inventor:(Graham Gunderson). Result: positive.

Findings

  • US 2006/0163971 A1 was granted as US 7,830,065 B2 on 9 Nov 2010 (same application 11/336,337) [web] https://patents.google.com/patent/US7830065B2/en. facts.json said the grant status was unknown, so this fills that gap.
  • CPC classification shown for both A1 and B2: H02K53/00 "Alleged dynamo-electric perpetua mobilia" [web]. This is the classification office's label, not the applicant's.
  • Assignment chain (USPTO legal events via IFI CLAIMS) [web]: Gunderson to Magnetic Power, Inc. (CA), reel 017488/0430, effective 20 Jan 2006; Magnetic Power, Inc. to Chava LLC (FL), 025082/0405, effective 27 Sep 2010; Chava LLC to Chava Energy LLC (FL), 036144/0136, effective 9 Jul 2015; Chava Energy LLC (Nevada) to Chava Energy LLC (FL), 047878/0130, effective 20 Dec 2018. The 4th- and 8th-year fees were paid (the 8th late, with surcharge). The patent lapsed for non-payment of the 12th-year fee (effective 9 Nov 2022).
  • Granted text differs from the A1 publication. These are wording changes made during prosecution. In the B2 description:
  • "without the necessity of consuming limited natural resources" became "with far greater economy ... reduce the size and weight", with uses listed in aviation, automotive and handheld devices.
  • "The present invention synthesizes virtual motion" became "is believed to synthesize virtual motion ... thereby providing highly efficient energy conversion".
  • "requiring only a small electric force to operate" became "a highly efficient energy conversion apparatus".
  • The [0036] "addition, and resulting acceleration ... does not require consumption of natural resources" became "not cause opposition, resulting in efficient magnetic field motion".
  • The [0048] sentence "This situation persists until the magnets are no longer magnetized" was deleted.
  • In [0049], "advantageous re-generating effects" and "a reduction of required input power as loads are applied" were deleted.
  • Retained unchanged: para [0044] ("absence of electrical loading at the input and/or an overall amplification of the input signal ... as increasing amounts of energy are withdrawn ... decreasing amounts of energy are generally required ... until they are demagnetized") and para [0040] ("Experiments show that high-quality permanent magnets can be 'pushed against' ... for very long periods").

  • The granted claims differ from the published claims (11 claims, not 10) [web]:
  • Claim 1 now requires "a resonant circuit, having a square wave energy input source, in direct electrical connection with said wire coils".
  • Claim 8 (Earth's field) changed from "in substitution of" to "supplemented by".
  • New independent claim 11 recites the full geometry: a cylindrical core with radial holes, N pole above and S pole below, a toroidal input winding, and an output wire woven through consecutive holes. It ends: "whereby the interaction ... improves the efficiency of the conversion device".
  • No claim recites over-unity.

  • US 8,093,869 B1 [web] https://patents.google.com/patent/US8093869B1/en:
  • Status "Active", adjusted expiration 29 Aug 2029. Fees were paid through the 8th year, late with surcharge in Oct 2019.
  • Gunderson assigned it to Chava Energy LLC, reel 027338/0270, effective 23 Nov 2011, followed by the 2018 Nevada-to-Florida Chava transfer.
  • CPC H02K35/06.

"Sound wave resonance generator" US20110233941A1, priority 3 Dec 2008, the same day Gunderson's non-provisional was filed; Sumitomo Riko (Tokai Rubber) WO2014119202A1 magnetostrictive vibration power generation; Mitsumi WO2015002069A1; Oscilla Power WO2015116275A3; Qualcomm US9601267B2; Gilstad US9879507B2; US DOE US9960341B1 high-frequency magnetostrictive transducers.
  • Inventor search "Graham Gunderson" finds only these two families [web]. No foreign family members are listed under "Worldwide applications"; both are US only. No later published application from the 2016 provisional (see energeticforum notes) was found under his name.

Bearing on the claims

  • Claims 1-2 (solid-state generator, Lenz "aiding"): the granted text keeps the central [0044] energy statement. It softens or removes the resource-free and "persists until demagnetised" language and adds "believed to".
  • The Patent Office classed the family under H02K53/00 "alleged perpetua mobilia" yet granted the structural claims. That is the office's characterization.
  • Claims 3-6 (the acoustic patent): a large body of mainstream magnetostrictive energy-harvesting work cites it (DOE, Oscilla, Tokai Rubber, Mitsumi). That is related work in priority 3.
