When the patent expires?
If I'm not wrong Industrial Patents restrictions applies for 10 or 20 years, but no more. —Preceding unsigned comment added by 95.19.4.62 (talk) 10:08, 7 November 2010 (UTC)
- Well presumably the EV market will be flooded with NiMH battery cars, as all the people who have been prevented from using them will be able to. Or not. Greglocock (talk) 06:35, 10 November 2010 (UTC)
- FWIW I have a note to myself that the patent/s expire sometime in 2015 -- less than 5 yrs from now. But this really doesn't matter since auto manufacturers are already working around those patents w/Li ion. Toyota-Panasonic-Sanyo have entered into an agreement re long-term NiMH manufacturing for auto use. When 2015 rolls around, the patent/s expiring may help lower the cost of NiMH for autos which will force down the cost of Li ion to compete. And if Eestor finally offers an ultracap that lives up to the hype, who cares about batteries. Phantom in ca (talk) 01:31, 14 January 2011 (UTC)
What patent? It doesn't even make sense to ask when "the patent" expires, given that no patent is identified as "the patent". — Preceding unsigned comment added by 204.227.241.38 (talk) 18:57, 5 December 2011 (UTC)
The Wiki article on NiHM list the patent as: 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)
- In that case, according to the USPTO Maintenance Fee search function, that patent has lapsed for failure to pay maintenance fees during the 8 year window, in 2010. 204.227.241.38 (talk) 16:06, 5 February 2014 (UTC)
- I found the patent on the website you mentioned, but no notice of when it will expire or when it has lapsed. Care to enlighten us? 2A02:120B:2C11:2F80:98C6:C44D:72E:D09B (talk) 17:35, 1 February 2015 (UTC)
Out of Date
As of Feb 2015, this article is badly out of date and needs a total re-write. The magical 2014 date that we've been waiting for years for has passed and so what. You still can't seem to get large format NiMH cells. What's the real story here? Where are these large format cells, who can make them, who is going to use them and why? What's happening with Nickel-Iron batteries or other derivatives which don't use Lithium? — Preceding unsigned comment added by 210.86.93.147 (talk) 00:05, 9 March 2015 (UTC)
The patent nominated above expired in 2010
I suggest that in the ensuing 5 years nobody has flooded the market with large format NiMH powered EVs because there are better technologies. As to other battery chemistries, look them up, they don't belong on this page. Greglocock (talk) 08:23, 9 March 2015 (UTC)
