Can a minor copyright or trademark? Am I allowed as a minor to copyright materials and trademark names in Utah?
Federal law governing copyright, and state and federal law governing trademark, do not make any stipulations about the person enjoying the particular property right. In lieu of a specific restriction, the person may be an alien, a prisoner, a public employee, a corporation, or an astronaut. There are limits on minors and contracts, but no contract is required to write a book, make a sculpture, or create a distinctive business mark. (Those limits potentially raise questions about a minor signing away their author's rights if they create a work for hire, which you didn't ask about. A contract is typically necessary to profit off of such a creation, but not always). The copyright office even says that you can register copyright (important, registration is necessary to get maximal protection). There is a bit of an issue that a minor has limited ability to sue (for infringement), so in Utah Rule 17 you would need a guardian to sue for you, likewise in federal court (same number!).
Some MP3 technologies are still under patent in the US: you can read the wiki page on that matter to see if it is applicable to what you intend to do. This assumes you write your own code – if you use someone else's conversion software, that would depend on the licensing terms for the software.
No. The "pricing structure" here is essentially an algorithm. It can be patented but not copyrighted.
No. The Creative Commons license seeks to promote recognition of the original author's work through attribution, but does not provide the same framework for enforcement that the DMCA would. The proper approach in cases such as the deleted Wikipedia article and subsequent reuse would be to provide a courteous notice to Wikipedia of your original publication and ask to be listed as the original author or be provided attribution. In the absence of relief there, then what rights you have would be determined by the Wikipedia Terms of Service. Since, and I am assuming here, that you are not generating billions of dollars on the original publication in royalties, seeking to bring a DMCA type enforcement on a Wikipedia article dispute would be like trying to swat a fly with a sledgehammer. (or more commonly in divorce, two people having hearing and spending thousands of dollars on attorney's fees fighting over a blender -- they are free to do it, but they would have been much better off buying 500 new blenders...) Keeping perspective and providing a courteous letter is probably your most cost efficient first step in situations like this. And in all areas of law, just remember, you catch more flies with honey than you do with salt. (meaning taking the courteous approach usually affords better results than a scalding letter breathing hell-fire and brimstone) In followup to earlier comment: Presuming you would be covered by the World Intellectual Property Organization Treaty on Copyright of 1996 (as a U.S. Citizen you would be), and your copyright is on file with the United States Copyright Offices (same presumption) as prerequisite to suit, then there is nothing that prevents you from invoking the protections under general copyright law and under the DMCA (inlcuding the Takedown provisions). Note: these are not the only prerequisites to taking action, but instead the minimum critera to qualify, and note this does not pass on the wisdom of doing so (there are often significant consequences to improperly invoking previsions of certain acts).
Copyright in the US is usually a civil matter. Meaning that the copyright owner can sue (typically for money damages or injunctive relief) an infringer. The criminal laws that we have are aimed at the reproducer and/or distributor. In other words, chances are that you won't get in any criminal trouble for accessing academic articles of dubious origin. But never say never. RIP Aaron Schwartz.
It depends on what information you are sharing, how you got it, and what rights the business asserts over the information. For example, if it is content created by the business and they claim copyright protection you can only use it without their permission in accordance with Fair use exceptions. If you obtain the information through some limited/conditional access agreement you would be subject to the terms of that agreement. As always: If you want a legal opinion specific to your use case you need to consult a lawyer in your jurisdiction.
No If they have prior usage then they have the trademark already and are the only ones who can register it. Trademarks arise through use - registration is not required.
Generally, it's illegal. You are creating a derivative work and you are not allowed to do that without the permission of the copyright holder. Some jurisdictions may have exceptions, such as fair use under US law. However, this generally protects uses that are intended to comment on or parody the work. It doesn't sound like that is the purpose of your image modification. NOT including: faceswaps, modifications that would shame or affect negatively the reputation of the actors on the image. That doesn't make it legal. I share it in a way that I don't make any economic profit out of it, and clearly stating that it is a modified image (not sure if inside the image, or in the caption under it) and state who is the legal owner of the original image. That doesn't make it legal, either.
