Is the RRFB Dead?

From the rumor mills:

The patent holder is digging in his/their heels on the situation  [/li][/list]

Gotta wonder if he's trying to go out with a bang. If he digs his heels any farther, no one's going to make any money selling RRFBs stateside.

It appears WSDOT was ready to go with a solution -

I know of at least one other agency that is moving forward with the WSDOT solution as a stopgap measure until the RRFB comes back (or doesn't come back).

Looks good. Basically the same setup, except with circular flashing LED amber bulbs (8 inches below 40 mph, 12 inches above) placed over the W11-2 signs, instead of below. Seems like a good stop-gap measure until the RRFB mess is sorted (if at all).

That's basically what I was suggesting in a previous post. I like it. Looking at the links there, it appears WSDOT is also using a rapid flash pattern but it is different from the RRFB patterns I've seen. Still curious if this set up could be used with a flash pattern used on RRFBs (I like the original 2-3/2-5 pattern or the wig wag+simultaneous patterns I've seen around Nevada).
