"Did you know, for example, that content optimization on your device’s screen when switching between portrait and landscape video is a Nokia invention? And fast forwarding or rewinding a video by scrolling through it, while simultaneously displaying the current scene"

That is actually a direct quote lol

Sheesh, I should patent urinating after drinking a beverage, that’s about as novel of an invention.

As for fast forward and rewind while seeing the current scene, we did this back in the days of the VCR. Are they claiming to have invented that?

  A VCR would simply display the frames that happened to pass by the read heads while rewinding. When doing that digitally, your codec decides if that is even feasible. If the codec optimizes for disk space, generating any frame requires going through all previous frames. If the codec optimizes for fast scrubbing, the file must contain redundant information and thus be larger. Nokia is claiming that h264's checkpointing mechanisms allow for that (empirically, this is indeed a feature of h264) and it is therefore their invention. I'm unaware if previous codecs had similar mechanisms. It would be wierd of none had, but it wouldn't surprise me that much.

    MPEG2 has I, P, and B, frames, so unless they "refreshed" the patent is somehow old, someone at Nokia just came up with the scrubbing idea using the existing implementation. ...But video players have had scrubbing bars for a long time? I'm not sure how long, my memory on Windows on XP and older is fuzzy.

    > generating any frame requires going through all previous frames No it doesn't; that would be crazy. There are keyframes that can be decoded independently of any other frame. They're usually every few seconds at most, which is fine for scrubbing.

So afaik Nokia did not patent and enforce that. Meanwhile e.g. Apple has very strongly enforced similarly silly UX patents. (E.g. rubberband/inertial scrolling and quite a few more.) They have also very strongly enforced silly design patents - e.g. for rounded corners on physical devices.
