I've no idea as to the validity of said rumor...

i remember there was a post probably about a year talking about the srm patent expiring and to the best of my knowledge i think it has 2 more years.Roadie_scum said:There are so many good contributors on this forum now, and I check in less, but finally something I can contribute on.

No way can you renew a Patent after the expiry of its term. You have to pay a small fee to keep it registered over the term (could be considered a renewal), but when it's over it's over. I think the SRM is now about 20 plus years old? That would mean its patent has expired in all jurisdictions...
Interesting. What do you see as the needed improvements on existing PM's that are not blocked by patents?Squint said:I thought it expired last December. No matter, since it's not measuring at the chainwheel spider that's holding back most other powermeter manufacturers. The improvements they need to make are not blocked by patents.
Did SRM ever have a US patent? What's the patent number?Roadie_scum said:There are so many good contributors on this forum now, and I check in less, but finally something I can contribute on. Patent law! Brilliant...
