I'm not so sure that Apple has ANY patents on their user interface. Software alone is EXTREMELY difficult to patent; what Apple did is copyright the "Audio-visual work" which is their screen display; this prohibits unauthorized copying (no one else can produce a display like that without Apple's consent.) That doesn't prohibit anyone from having an interface that WORKS like Apple's, so long as it doesn't LOOK like Apple's. > >I don't know if you've ever looked at the patents for the Telebit >Trailblazer modems, but they are worded in such a way that they could >almost be applied to *any* modem.

If a patent like that is ever challenged in court, say because the patent holder trys to enforce it, the defendant can show that the method was not original to the patent holder, and the patent can be invalidated. Patents can be invalidated for other reasons, too, such as the invention being "obvious" -- i.e. ANYONE could have thought of it, if they had the need. You can't patent simply anything you want; it must be worthy of the law's protection. Otherwise things would get out of hand with everyone trying to make a quick buck by patenting anything and everything, in order to charge other people for the privledge of using it. Patent law exists to protect ORIGINAL, NON-OBVIOUS, and USEFUL devices, methods and processes. The Patent Office examines a patent when it is filed, to insure that it conforms to these requirements. Sometimes, they make mistakes; the patent can be challenged and the question is decided in court. Copyright exists to protect works of authorship, such as books, music, software, and visual arts including video displays. When someone, such as a composer, believes that someone has infringed on his copyright, he takes them to court. For music, the courts have set up some pretty clear guidelines on what constitutes an infringement. If an average person (they don't have to be any sort of musical expert, or have any special qualifications) can detect a substantial similarity, and there is a reasonable chance that the alleged infringing author had prior exposure to the other work, then the work will be considered infringing. A recent example of this was the John Lennon tune "My Sweet Lord", which was found to infringe on the copyright of the song, "He's So Fine". It doesn't matter that there is or isn't INTENT to copy. The court determined that there was a reasonable chance that Lennon had had exposure to the tune, and the jury could hear a substantial similarity in the music. On the other hand, if two composers who could not have had exposure to the other's work produce similar tunes, they would not be found infringing, because they were produced independently. If similary criteria are applied in this case, then a substantial similarity in appearance to the copyrighted Apple screens could result in a determination of infringement. There can be no question of prior exposure, because one of the defendants had a limited license to the Apple technology. It's a matter of what criteria the court uses to determine substantial similarity. Please note: The above is in no way to be construed as legal advice. These are my opinions. If you want legal advice, you should consult a lawyer. I am just a programmer who has an interest in protecting his work.
