Better? It is certainly "different". Copyright lasts for a fixed period. Trademark lasts as long as the owner continues to use it. You can have trademark rights on things that cannot be protected by copyright and vice versa.
If it's a creative work, if would be protected by copyright law automatically.
If it's a mark to be used in trade, such as a business name, slogan, or logo, it would be protected by trademark law automatically.
Products are better protected by trademark than copyright; registration can be done online at the link below.
Products such as the Kinect are protected by trademark and patent rather than copyright (which would protect individual games, for example). Microsoft filed for a US patent January 20, 2009, registered a trademark April 29, 2010, and released the product in November 2010.
Goods and services are protected by trademark rather than copyright; copyright protects original creative works. For the purposes of trademark registration, goods and services are divided into categories ranging from chemicals to personal services.
No, there is no such requirement.
You would want trademark protection rather than copyright protection. The trademark office of the country in which you wish to do business should have information online, and may have an online application process.
Using NFL or team logos requires a license; this is an issue of trademark, rather than copyright.
A trademark is a word, phrase, symbol, and/or design that identifies and distinguishes the source of the goods of one party from those of others. A service mark is a word, phrase, symbol, and/or design that identifies and distinguishes the source of a service rather than goods. Some examples include brand names, slogans, and logos. The term "trademark" is often used in a general sense to refer to both trademarks and service marks.
Typically you would want to protect your product through trademark or (if it's an invention) patent law, rather than copyright. The US Patent and Trademark Office has very clear walkthroughs on its website (link below); outside the US, your country's trademark and/or patent office likely has a similar process.
You can copyright a work, but generally not a story title. In any case, you don't have to go anywhere to copyright. Copyright ownership is automatic, because of the work done. Unless a copyright was sold or gifted you need a proof that you did the work to claim a copyright but nothing more than that.
It is more likely to be a trademark violation than copyright infringement.
Generally mascots and other logos are protected by trademark rather than copyright.
To qualify for a patent, it would need to be innovative and non-obvious, and the patent application process might be more elaborate and expensive than you would like. Copyright might protect designs, say a pattern of intricate piping, but more as a piece of art than a piece of food. You may find that trademark is the most appropriate direction to go in. There are any number of registered baked goods in the world.
