What is the difference of trademark (TM), registered (庐), and copyrighted (漏)???

Copyright is where someone is the author of a work or the artist/photographer. It applies to all written work and art works unless the originator knowingly and willingly assigns it to another. It means that what has been created cannot be reproduced without the express permission of the copyright owner. Otherwise, they're breaking the law. Copyright in the UK lasts for the lifetime of the originator plus 70 years. Sometimes the copyright is passed on to the estate of the originator.

TM is applied to products, slogos, logos, company names etc by the owner. I think I'm correct in saying that it's not really enforceable in law.

What protects it is by registering it and it becoming a registered trade mark. Anyone copying it - the McDonalds golden arches, for example - would be liable for prosecution.

Hope this helps

Trademark:

Trademark is a work, name or symbol used in trade goods to distinguish them from the goods of others. Trademark rights may be used to prevent others from using a comfusingly similar mark.

Registered:

All trading organisations that issue australian qualifications framework and statements of attainment must be registered by a state of Territory recognition authority. The Vocational Education and Training Accreditation Board (VETAB) is the recognition authority for NSW, and it grants registration for up to five years.

1. Only Registered Training Organisations (RTOs):

2. can issue qualifications and statements of attainment that are recognised nationally
3. can use the VETAB and Nationally Recognised Training logos
4. are listed on the National Training Information Service (NTIS) database
5. can be approved to provide courses to overseas students studying in Australia and listed on the Commonwealth Register of Institutions and Courses for Overseas Students (CRICOS)
6. are eligible to tender for public funding for vocational education and training.
An organisation that is not registered may offer training or assessment services, but cannot issue nationally recognised qualifications.

Copyrighted:

Copyright is a set of exclusive rights that regulate the use of a particular expression of an idea or information. At its most general, it is literally "the rights to copy" an original creation. In most cases, these rights are of limited duration.

The symbol for copyright is "漏". The letter C inside parentheses ("(c)"), although a common practice, has never been a legally recognized designator.

Copyright may subsist in a wide range of creative, intellectual, or artistic forms or "works". These include poems, theses, plays, and other literary works, movies, choreographic works (dances, ballets, etc.), musical compositions, audio recordings, paintings, drawings, sculptures, photographs, software, radio and television broadcasts of live and other performances, and, in some jurisdictions, industrial designs. Designs or industrial designs may have separate or overlapping laws applied to them in some jurisdictions. Copyright is one of the laws covered by the umbrella term intellectual property.

Copyright law covers only the form or manner in which ideas or information have been manifested, the "form of material expression." It is not designed or intended to cover the actual idea, concepts, facts, styles, or techniques which may be embodied in or represented by the copyright work. For example, the copyright which subsists in relation to a Mickey Mouse cartoon prohibits unauthorized parties from distributing copies of the cartoon or creating derivative works which copy or mimic Disney's particular anthropomorphic mouse, but does not prohibit the creation of artistic works about anthropomorphic mice in general, so long as they are sufficiently different to not be deemed imitative of the original. In many jurisdictions, copyright law provides scope for satirical or interpretive works which themselves may be copyrighted (See Fair Use). Other laws may impose legal restrictions on reproduction or use where copyright does not - such as trademarks and patents.

Copyright laws are standardized through international conventions such as the Berne Convention in some countries and are required by international organizations such as European Union or World Trade Organization from their member states.
