For anyone unfamiliar with patents - companies like Sony file a shitload of patents every year that they never end up using. Until more info comes out, the patent itself means little.

For context, Microsoft has a total of 124462 patents globally, not all of which have been granted. These days it files about 3000 new patents every year. A lot of them are very vague, some don’t make any sense at all, and many are never put to any use.

Apparently Sony has even more patents than Microsoft, currently sitting at nearly quarter million. However, only a third of them have been granted so far.
