Proof required

Please provide patent numbers to provide credibility to this conspiracy theory. 12.184.83.66 (talk) 08:13, 13 March 2009

Claims in the article are fully referenced. The specific patent number would not add value to the article. Fbagatelleblack (talk) 04:42, 14 March 2009 (UTC)
But a listing of patents awarded to Mr. Ovshinsky for battery technology might be useful anyway. His name is unique enough that a patent search is unlikely to turn up patents from other people.
A search of PatentStorm for the search terms Ovshinsky and battery reveals 249 hits, though some of these may be other people's patents referencing the man's work. I am on a slow connection so I am not going to wade through this right now..

The list is very interesting in that you can see the company has continued to be awarded patents for battery technologies, even if they aren't actually selling much of anything to anyone. Owning the patents for this technology for the next 17 years or so is probably more valuable to Chevron as a controlling interest, than the production of the technology itself.

If you linked to the patents then people could see for themselves when the patents expire. --24.85.247.169 (talk) 15:52, 20 April 2012 (UTC)
It is impossible to evaluate the claim that there are industry blocking patents in the absence of any citation to actual patents. Lots of Ovshinsky's older patents have been expired since the turn of the century. I don't know whether those are the alleged blocking patents because nobody's said which ones were the ones that have supposedly kept the world from getting their electric cars. 204.227.241.38 (talk) 18:39, 17 November 2011 (UTC)
If you feel the article needs to be improved, please edit it. You seem to know something about the subject matter. Your help would be much appreciated. Sincerely, Ebikeguy (talk) 16:38, 20 April 2012 (UTC)
Unfortunately, I only know patents. I don't know anything about which of Ovshinsky's patents are supposed to be the important ones or I would edit. — Preceding unsigned comment added by 204.227.241.38 (talk) 14:19, 1 June 2012 (UTC)

The Wiki article on NiMH batteries links the following as "the patent" in question. I'm going to add it to this article on the assumption it is the correct patent. US patent 6413670, "High power nickel–metal hydride batteries and high power alloys/electrodes for use therein", published July 2, 2002  Phantom in ca (talk) 17:30, 27 December 2013 (UTC)
