naming - On copyright laws and plots

I was pondering a lot on the issue with copyrights on plots. Is having an identical plot infringing someone else's copyrighted work?

I am fully aware that the character names are copyrighted and cannot be copied. I am also fully aware that the representation of the idea (the words themselves, in substantial amounts) are copyrighted.

But what I'm curious about is the play, the plot points, the storyline, in other words, the idea behind which the words convey.

Let's assume I hold the copyrights of the Harry Potter books.

1. 
   

   If someone took all the pages of a Harry Potter book and rewrote each of them in his own words (when I say in his own words, I mean no simple task of rewriting. Paragraphs are removed, changed, added, dialogues changed, added, removed, even the chapters are different, the entire expression is different beyond recognition), plus he had renamed all the characters (e.g. Harry Potter to Gary Potter and so on). Although the entire expression of the idea is beyond different, the entire idea is identical. could I charge him for infringement by the copyright law? Could he publish his plagiarised work and claim copyrights for it?

   
   


2. 
   

   I see that the Harry Potter movies do not use words copyrighted by the Harry Potter book (spoken words, or written words which are shown on screen). Does it mean that if the movie were to rename all its characters (while having exactly the same plot), it is fully original by the copyright law, and the publishers (or movie makers etc) do not have to pay a single cent to me (the copyright holder of the Harry Potter books)?

   
   

Now let's take another example, this time on the web.

1. 
   

   If someone rewrote every single post in my blog in his own words and publish it, could I charge him for infringement by the copyright law? Could he publish his plagiarised work and claim copyrights for it?

   
   


2. 
   

   If someone rewrote all the content of my website (keep in mind that I'm not talking about programming code/design of the webpage) in his own words and publish it, could I charge him for infringement by the copyright law? Could he publish his plagiarised work and claim copyrights for it?

   
   

Answer

Technically you cannot copyright a plot. However, you can copyright a particular instance of that plot as long as it is not based on an older work in the public domain.

In your Harry Potter example if every chapter had exactly the same incidents and more or less the same dialogue with slightly altered character names you would probably lose in court trying to insist that yours is not just a rip-off. It's an area where the discretion of the court would come into play and you would probably be on the losing end of that discretion.

If, on the other hand, you wrote a story about a guy called Peter Thompson who, it turned out, was the son of the Greek god Mercury and went to "hero school" where it turned out there was some underlying plot to overthrow Zeus and incite war on Olympus and only Peter had the power to stop the plot with help from his two friends, a male and a female, on a jaunty magic schoolboy type quest JK Rowling's lawyers couldn't touch you.

Unfortunately Rick Riordan's lawyers would nail you to the wall for ripping off his "Percy Jackson" series.

However JK Rowling can't sue Riordan for his thinly disguised Potter rip-off. He's made Jackson sufficiently different that he's safe from the courts of civil law. The court of popular opinion, however, has branded him an unoriginal hack and his stories have not impinged on the public consciousness to anywhere near the degree of the Harry Potter series.

So, basically it's a matter of degree, and there are more ways for your work to be a failure than to be deemed infringing intellectual property in a court of law. On the other hand Riordan's ploy did get him a publisher... make of that what you will.

EDIT:

On your second point. In the electronic arena it matters whether the blog or website presented a work of fiction in which case, see above, or if what it produced was considered "news". In the latter case, well, just look at daily newspapers, they are all in the business of writing up the same source material in their own words. They call it bias. So if what you have on your website is "news" or "information" then it can be copied by someone else in their own words without issue. See also textbooks for examples of the same information rendered by different people in different words. If the work is creative, imaginative and "original" (such that it is not based on information in the public domain) then the rules apply as above.

Finally, to clarify one point I've now made twice. If you decide to write your own version of Snow White someone else may also write theirs with the same sequence of events and even the same character names as long as they don't steal any original elements that you added to the story (like Red Riding Hood's utility belt and addition of her sidekick "Sparrow" the girl wonder). Even then it gets a bit complicated and nothing is certain no matter what Disney's legal team will tell you.

And while I was writing that paragraph I remembered one other thing. Technically if what you have written is deemed "satire" in some areas that gives it special protection under "freedom of speech" a court ruling once set a precedent that zombies were a satirical device therefore adding zombies to anything instantly protects it as satire. This is, of course, a broad interpretation but it does serve as an example that all I have written is suspect and you never can be sure.

SECOND EDIT: And on your point about a movie that was very similar but sufficiently different not to occasion a lawsuit see National Treasure. The story goes that Disney wanted to buy the rights to The Da Vinci Code and lost the bid, so they made National Treasure. As you may note National Treasure is so sufficiently different from TDVC that it exists now as a thing in its own right having features not shared by the original work (e.g. IMO "fun"). Therein lies the problem in such a ploy. People who love "Lord of the Rings" want to see "Lord of the Rings" they don't want to see "Halfling and Elfboy's Bogus Questathon", so essentially by making your product sufficiently different you have also ensured it will have its own audience leaving the audience for the original pristine and unsullied.
