Actually, the Copyright Act was replaced entirely in 1976 (becoming effective in 1978), and has been amended some, yet in substantial ways, since then. Noises are being made about a new Copyright Act coming along in the near future.

The person who wrote the summary is a bit confused. What happened is that the Warner claim was based on a copy published in 1935. Evidence was discovered of a copy that was published in 1927. That's not terribly interesting, but a copy published in 1922 has also come to light. That is interesting, because the cutoff for copyright on published works is 1923. (Due to the duration of copyright prior to the effective date of the 1976 Act, which retroactively lengthened the term of copyrights that were still in force)

No, that part of the trademark will lapse when the copyright terminates. A trademark can't function as a substitute for a copyright. The remainder of the trademark might prevent people from selling MICKEY MOUSE brand breakfast cereal, but it would not stop them from using the character in their own works.

This is really the main reason that Disney is concerned about copyright terms; they know what would happen to the trademark.

Piffle.

Copyright is utilitarian from top to bottom.

Copyright is only tolerable if it is better for society than not having it. One specific implementation of copyright is better than another if it provides a greater benefit for the public than the alternative.

It's no more based on fairness than a zoning regulation requiring a certain setback from the street.

A small nit here:

An exclusive right isn't a right that is held only by one party (and in fact, copyrights can be held by many parties), but is literally a right to exclude others.

So copyright isn't a right to make copies (that's free speech, and it applies even to works that aren't eligible for copyright). It is instead a right to exclude other people from making copies, and from doing certain other things with regard to the protected work.

Letter shapes are not copyrightable in the US. They may be eligible for a design patent, but that's relatively short-lived. Usually the only protectable thing, especially over a decent timeframe, is the name, as a trademark. That's why Apple's version of Helvetica from way back was called Geneva, and Microsoft's was called Arial.

We do.

We impose taxes on inheritances, because inheritance of substantial wealth is harmful to society. We impose taxes on property, because ownership of large, unproductive estates is harmful to society. We abolish property rights like the fee tail because inalienable property rights are harmful to society.

All property rights, beyond what an individual person can defend from others by force, relies entirely on the willing cooperation of others. The only reason I don't own the Brooklyn Bridge is because I can't convince enough people that I do. But if I were more convincing (or could overcome the force that would be mustered against me if I just tried to block others' access to it), my right of ownership would be perfectly legitimate.

Copyright operates similarly; no author has a right to tell others that they can't make copies, etc. of a work, merely because the author created it. All the author can do is keep the work a secret, if he's worried about that. Or he can convince others to respect his wishes. Just as you might not like to recognize my right of ownership of the Brooklyn Bridge merely because I really, really want you to, so too are third parties unlikely to honor a claim of copyright unless it provides some benefit to them that would not be enjoyed otherwise.

And so the deal with copyright is that we're willing to recognize an author's claim of copyright for a little while, because it seems to be useful to society, but eventually we're going to stop, and instead treat the work as being in the public domain, for the same reason. Authors can't stop that from happening, and there's too little benefit for the public in a perpetual copyright to bother recognizing them. It's a one-sided deal in favor of the public, but thems the breaks.

No, the whole point of copyright was to promote the progress of science (which is an archaic term for knowledge) and to thus serve the public interest.

Half of that involves encouraging authors to create and publish works which they would not have created and published but for copyright. But the other half is to grant the least amount of protection, for the least amount of time, that is necessary to accomplish that.

And the success of any copyright law is measured in how much of a benefit it provides for the public (in terms of the number of works created and published), less how much harm it causes the public (by restricting the free use of the works).

No. First, copyright doesn't guarantee any reward for the author or publisher; that's left to the market. All copyright does is funnel some of the profits available for the work toward the copyright holder. If a work is a flop, the copyright holder doesn't make any money.

Second, copyright doesn't care about quality. A brilliant work gets as much protection as a crappy one, (and again, the market may reward crappy works over 'quality works). This is necessary because artistic value is a matter of subjective judgment that the government should not be involved in. Quantity is the only permissible metric, and since a larger number of works will tend to result in a larger number of 'quality' works (see Sturgeon's Law) it's all okay in the end.

"Relatively recently?" What are you, a highlander?

The 14+14 term you describe lasted from 1790 to 1831. Then it became 28+14. And in 1909, it became 28+28. That's the term that changed relatively recently, in 1978, to life + 70, etc.

Still, kudos on the general thrust of your argument.

Well, it's a little more complicated than that.

The sine qua non of a trademark is that all goods with the same mark originate from the same source. If this is true, the mark can be protected. If not, the mark cannot be protected. This is why trademark holders are always concerned with infringers; if the infringer is not stopped, there will be identically marked goods originating from different sources, and the protected status of the mark is jeopardized and can be lost.

Trademarks and copyrights only sometimes overlap with regard to the subject matter that they protect (e.g. a very artistic trademark could be protected by copyright as a work of art; a mere word used as a trademark could not be copyrighted, however). However, copyright is considered the superior right; a trademark is not allowed to function as a substitute for a copyright, nor to interfere with copyright policy.

This means that if the trademark is a character from a creative work, and the work is in the public domain, copyright law allows everyone to make copies and use the work and thus the character from the work, as they see fit. Trademark rights in the character can't interfere with this, so to the extent that there is a conflict, the trademark loses.

So the MICKEY MOUSE trademark might survive with regard to products unrelated to creative works, like those ice cream bars that looked like a Mickey Mouse head. But it would not survive with regard to movies, books, comics, television shows, etc. And I wouldn't want to bet money on whether it would survive with regard to things like t-shirts or hats that might feature Mickey Mouse in an ornamental capacity, rather than as a trademark. So a lot of the merchandising gravy train would derail.

"I really don't give a crap though..."

The people around you are being abused, in my opinion. Everyone should care.

Another example of abuse: Bill allows government to revoke Americans' passports without charges or trial.

Yes, you know how to do that. VERY few PC computer users would know how. So, the practice is abusive toward most users.

Windows 10 is not "free". Windows 10 is apparently intended to take more control. For example, now Microsoft says it can take and make use of your data: Windows 10: Here are the privacy issues you should know about.

Microsoft will now have full control over Windows Home users with "updates". Microsoft often publishes buggy updates. Judging from the way things are moving, that is just one step to increasing control. Microsoft will apparently arrange even more domination later.
