I'm not sure how much you follow patent law, but there are a number of 'corporations' that have formed just to create patents. They have no intention whatsoever of using them to create anything, but exist solely to play 'gotcha' when a company creates a product that also creates a similar method of going about a product. The patent troll then says 'hey, we have a patent on that' and sues them. It's created a big booming business that seems to only recently been getting some backlash from the courts. Tresona is in fact an identical 'business model' in my opinion.
They formed by going to the copyright holders and saying, 'hey, we'll help police your infractions if you tell people to license through us.' When they first came on the scene there was even some potential benefit in them becoming a one-stop company to do your licensing. Unfortunately one of the first things they seem to have done is raised the price of doing legal arranging. I've heard your minimum rights have gone up to at least $500/copyrighted work right now. (Personally I have avoided anything with this by sticking to public domain melodies/works)
Two years ago Tresona began venturing into litigation with DCI, then BOA and USBands. I think DCI was the easiest first target and you watched them clear out their old DVDs of performances quickly. As a high-profile target I believe they fought back some, but they have no education backup law there and I believe they eventually settled. I know BOA and USBands were sued going into last marching season. USBands provided a service last season where you could go into a clinic with the film of your band and the judges. They had already guaranteed the service but ended up spending $30,000 to honor their agreement with bands for those contests. They stated no more video would be done at their contests as part of their settlement. It was also a race to get bands to show they did in fact have permission to arrange any and all shows. Anyone who didn't was contacted by Tresona and strong armed into doing it or being sued and paying the much higher civil penalties.
I know of at least one band director who then had to pay out of her own pocket to get 'right' with the devil there. BOA last season also washed their hands on recording their competitions. I find it ironic that I almost think the count of YouTube videos is going up now with this and I personally think this is a horse out of the barn scenario.
More interestingly to me is that Tresona is also going after cheer, dance, and show choirs. UIL had State Cheer issues last year from what I understand. Tresona also sued the Show Choir that was the inspiration for 'Glee,' Burbank High School. This is one of the few cases where the school has said 'we'll see you in court' and Tresona got their legal rears handed to them. (You can search the case online Tresona vs Burbank)
It sounds like Tresona's next step is going to be 'We'll let you record for '$X.' Personally I believe the educational exemption for many things including 'archives' should come into play here for at least UIL. BOA and USBands don't really have an educational protection, but UIL is sponsored for schools by the state. I suspect that in court - especially a Texas court of a judge who grew up in Texas - you would see UIL prevail. On the chance they would lose though they seem to have caved.
