Unfortunately tech companies (etc) regularly patent things not because they are possible or because they are working on them but for other reasons (eg: to profit if someone works it out, to block others from developing things, as wild "just in case we need it in 30 years", etc). Just registering a patent means almost nothing about the future chance of things happening. Because the patent system is broken.
