Well.... I'm guessing my 5 yr old son knows about as much about patent law as I do but in much more simplistic terms, that would be pretty unwise of Mr. Bush to go on record in support of them then, huh?
Another novice (3rd yr) beekeeper here.. - I was skeptical too but I can also envision a few ways to go about something like this.
This looks like their method & patent.
The other methods I envision would require the frame to be removed & cleaned before reuse by the bees.
