Is a trademark the same as a copyright ?
No, it's not. The owner of PUSH had a trademark on "PUSH" -- a robotic trashcan. So they were basically the only ones that could have a robotic trashcan named "PUSH". However, I'm pretty sure that Disney owns the copyright on the coloring and logo for the actual shell of the trashcan. There was nothing stopping Disney from creating their own robotic trashcan, they just couldn't call it PUSH. However, the owner allowed the trademark to expire and there doesn't seem to have been any effort to revive it.
Abandonment
Trademark rights must be maintained through active, lawful use of the trademark in the regular course of business. If the trademark owner does not respond to the USPTO to maintain the trademark within the six-month grace period, the trademark may be considered abandoned; however, the office does not officially post the trademark as abandoned for at least two months following the expiration of the grace period. Extension requests are granted in six-month increments; five extensions may be filed.
Reviving the Trademark
The abandoned trademark may be reregistered if the previous owner reestablishes its use, pays the fee and files a new registration before another interested party tries to register the mark. If there is no incidence of a similar trademark, and the previous owner meets the use standard, any other person who attempts to register the trademark as his own will be denied. A petition to revive a trademark registration is allowable only if the applicant has unintentionally failed to respond to the USPTO request.
Some additional differences between a copyright and a trademark are as follows:
1. The purpose of a copyright is to protect works of authorship as fixed in a tangible form of expression. Thus, copyright covers: a) works of art (2 or 3 dimensional), b) photos, pictures, graphic designs, drawings and other forms of images; c) songs, music and sound recordings of all kinds; d) books, manuscripts, publications and other written works; and e) plays, movies, shows, and other performance arts.
2. The purpose of a trademark is to protect words, phrases and logos used in federally regulated commerce to identify the source of goods and/or services.
3. There may be occasions when both copyright and trademark protection are desired with respect to the same business endeavor. For example, a marketing campaign for a new product may introduce a new slogan for use with the product, which also appears in advertisements for the product. However, copyright and trademark protection will cover different things. The advertisement's text and graphics, as published in a particular vehicle, will be covered by copyright - but this will not protect the slogan as such. The slogan may be protected by trademark law, but this will not cover the rest of the advertisement. If you want both forms of protection, you will have to perform both types of registration.
4. If you are interested in protecting a title, slogan, or other short word phrase, generally you want a trademark. Copyright law does not protect a bare phrase, slogan, or trade name.
5. Whether an image should be protected by trademark or copyright law depends on whether its use is intended to identify the source of goods or services. If an image is used temporarily in an ad campaign, it generally is not the type of thing intended to be protected as a logo.
6. The registration processes of copyright and trademark are entirely different. For copyright, the filing fee is small, the time to obtain registration is relatively short, and examination by the Copyright Office is limited to ensuring that the registration application is properly completed and suitable copies are attached. For trademark, the filing fee is more substantial, the time to obtain registration is much longer, and examination by the Trademark Office includes a substantive review of potentially conflicting marks which are found to be confusingly similar. While copyright registration is primarily an administrative process, trademark registration is very much an adversarial process.
7. Copyright law provides for compulsory licensing and royalty payments - there is no analogous concept in trademark law. Plus, the tests and definition of infringement are considerably different under copyright law and trademark law.
