Can pricing be copyrighted? Say a service is offered with pricing for 1 hour, 2 hours ... 12 hours. Assume there is some sort of custom calculation used to determine discounts after the first hour (e.g. if the first hour is $100, the second hour isn't necessarily $200 -- it would be less, and subsequent hours would be progressively less). If a competitor copies the exact pricing structure -- could that possibly considered copyright infringement?
No. The "pricing structure" here is essentially an algorithm. It can be patented but not copyrighted.
Algorithms are not subject to copyright. A particular implementation can be copyrighted, but an algorithm itself can't be copyrighted. Someone re-implementing the algorithm with their own code has done nothing to give you copyright claims against their work, and is not bound by any software license you use. That's what patents are for.
All your work is yours. They've made it very clear it wasn't a work for hire, so it's yours. They can't copyright any of their ideas. You can't copyright an idea. Only specific creative elements authored by them and present in your work could be covered by copyright. You didn't use their block diagrams. I don't see how references to other sites to look at would constitute a creative element they authored. That said, you probably want to talk to a lawyer and get a written legal opinion that you can rely on.
You seem to assume that copyrights require paperwork such as registration. This is wrong, copyright is automatic. And it prevents the downloader from making the sort of change that you suggest. In fact, it prevents the downloader from using your template at all. The only reason the downloader can use that template is because you've granted him a specific license to ignore some copyright rules, but the default remains. And you did not grant the right to alter the template to free users.
I would argue that no, there is no copyright for the restored work. Independent copyright is only possible for any original material added, as previously discussed on this site. In this case, the added work was a technical process rather than a creative process, and technical processes cannot be protected by copyright. Copyright licenses would therefore be ineffective. However, I believe one could still impose a license based on owning the copy as opposed to the copyright (contract might be a better term in this case). However, if a third party managed to obtain a copy through some other avenue, any such contract would not be binding on them and nothing could be enforced against them unlike with copyright laws. Another way a license might be imposed is through patent protections, as technical processes can be protected via patents. However, I'm not as familiar with patent law, and this doesn't appear to be the claim being made.
Titles can't be copyrighted. Meta-data like #2 aren't copyrighted. Not sure if the MPAA could protect its ratings, but I can't find anywhere that it has asserted restrictions on the use of those. If the list of "Similar works" is not somebody else's intellectual property then there's no problem. (If it is I'm not certain what protection it could be eligible for.)
I think the law there is quite clear - you have 14 days to return the goods for a full refund, except for digital content, which you can't return once you started downloading it. That's what it says. The arguments that you try to give were quite obvious to the law makers. I think you can assume they were aware that "digital content does not have a physical form". Now if you purchased, but haven't downloaded or started downloading yet, then obviously you can get your money back. You came up with some theory that this is a "visual vanity item". You can't see it unless you download it. Once you download it, that's it. If you don't download it, you can return it. Let me repeat this: Your fancy analogies mean nothing. There are in the EU laws about being allowed to return goods for a refund. There's the general rule for buying in a store (no right other what the store offers voluntarily), online purchases (some days to return), and online purchases of digital goods (no return once you started downloading). That's the law. Your attempts at redefining the situation are totally pointless. The law says what it says. What you try to redefine doesn't mean one thing. The law clearly distinguishes several situations, and analogies don't count. What happens counts. You bought from a digital item from an online store that needs to be downloaded. And as soon as you start downloading, there is your right to return it gone. And your reasons for wanting to return the goods are completely irrelevant. You don't need any reasons, and having reasons doesn't help you.
In the abstract, two businesses that cooperate in violating a third party's copyright could both face liability. Applying that information to the facts you gave would amount to legal counsel. If you don't want to tell the client 'no,' you should speak to a lawyer about your potential liability. Beyond the legalities, do you really want your portfolio to advertise that you design sites by ripping other sites off?
