For the 1st patent, based on the images, it seems that they have added a small analog stick which has been requested heavily by the community I might add. Surrounding the analog stick would be several buttons and at the bottom lies a trigger. There is also a handstrap at the side which is different from where normal handstraps on controllers are usually placed.
The other patent filed in 2017 is for finger placement tracking. This one specifically mentions the controller being tracked by the head-mounted display, which might suggest that a new head-mounted display will be introduced alongside the controller if it ever ends up being released in the market.
It is important to note that these are only patents for now and there is never a guarantee that they will ever be fully realized and released on the market but it is good to see that the company is looking for ways to improve on its ever expanding platforms, especially those which have just sold more than 2 million units worldwide.
