Carmanah Technologies Corporation today announced that it has purchased and disclaimed all patents restricting rectangular rapid flashing beacons (RRFBs) from gaining federal approvals in the US.

The History of the RRFB

Mr. R.D. Jones – Inventor of the RRFB (Rectangular Rapid Flashing Beacon)


In 2018, Mr. Richard D. “Rick” Jones decided to sell his patents to Carmanah Technologies Corp. so that Carmanah could disclaim these patents. By disclaiming the patents, Mr. Jones’ lifesaving RRFB technology was placed in the public domain. Now, all manufacturers of traffic control devices are free to produce the RRFBs without license or fear of patent infringement. This decision will undoubtedly reduce pedestrian and bicycle injuries and deaths as more and more RRFBs are deployed in crosswalks throughout America and around the world.
