Love your screen name btw. Do you really see infringement on Apple's part? Apple's tech is not just a button that rewinds a stored movie or show back 5 to 30 seconds, but actually uses context to replay what was said on screen (regardless of how long the statement onscreen was), and it shows you on-screen textually while re-playing.
It's not programmable to just go back 5 to 30 seconds. The only possible infringement I would see is when you ask Siri to rewind the show 5 to 30 seconds back, but even then I think they're making a pretty long reach that it's anything close to their very static rewind button. I'd be curious to know whether they've successfully challenged other tech companies, given a similar rewind feature has been around with things like Youtube (although not programmable, that I know of).
I was feeling a little dorky and self-indulgent on my "LawJolla" name day.
Thanks for your reply and good points.
I haven't done a through claim analysis, and I'm only loosely familiar with Apple's implimentation, so this is a little uninformed and off the cuff.
To infringe a patent, the alleged infringement must practice each claimed element. Practicing more than the claimed elements doesn't matter. Here's how I interpret it from a neutral observer.
A method of replaying a portion of a video comprising the steps of:
receiving, during a playing of a video, a replay request to replay a portion of a video;
While Apple TV is playing, a user somehow communicates a request to replay video, e.g. a button press followed by a spoken command
storing a request position of the playing of the video responsive to the replay request;
The Apple TV marks the video position where the request was made and stores it in memory.
skipping, responsive to the replay request, the video to a replay position that is responsive a preestablished replay preference;
Apple TV's video playback skips back to a previous frame. A lot could hinge on "preestablished replay preference." I suspect it'll be interpreted as any preference, including the one Apple hard coded at the factory, but "Pre-established replay preference" is odd wording. I also suspect when they were prosecuting this patent, they had to amend this claim here to overcome an examiner objection. That prosecution history is admissible to interpret the claim(s).
enabling a playing of subtitles;
This one is obvious.
playing the video and the subtitles from the replay position; and
This one too.
discontinuing the playing of subtitles responsive to the request position.
I don't know if this is true, but there's little ambiguous about this element. If Apple extended or shortened the subtitles about the "request position", it would not infringe.
That was the infringement analysis. Apple will also have an invalidity defense. They will attack the patent as invalid because it is either not novel and/or obvious given the prior art at the time (essentially that the patent office was wrong to ever issue it).
