" Patent filings should never be taken as truth " ?

From within the post New Patent Gives Us A Better Idea Of What's Behind Google's Mysterious 'Cinematic Reality' Investment

Of course, patent filings should never be taken as truth. Companies will patent a bunch of ideas that they might not end up using, just in case.

The post relates to work by Magic Leap.

Refer to published US application 20150016777, first inventor Rony Abovitz.

The first claim states:

A waveguide apparatus, comprising: a planar waveguide having at least a first end, a second end, a first face, and a second face, the second end opposed to the first end along a length of the waveguide, at least the first and the second faces forming an at least partially internally reflective optical path along at least a portion of the length of the planar waveguide, and at least one optically diffractive element that interprets the internally reflective optical path to provide a plurality of optical paths between an exterior and an interior of the planar waveguide via the first face thereof at respective positions along at least a portion of the length of the planar waveguide.
