Canon Patent Application: APS-C Compact Camera lenses

Our assumption with this patent application is that these lenses are for APS-C given the focal lengths of the lenses, however in this patent application, unlike most, the half image width is curiously missing from the patent application.  This could be for a mirrorless EF-M camera, or even a APS-C compact camera.  It's hard to tell without the image half width.  The patent description seems to be talking more about a compact camera.

The lens itself uses an element made of resin which is the basis of the patent application.

The lens embodiments shown in this patent are for two different lens speeds:

15-45 2.8-5.6
15-45 2.0-5.0

Of course with all patent applications, this may or may not end up in a production lens, but shows us some of the things that Canon is actively researching right now.

Update:

we missed an embodiment of a 15-60mm 2.0-5.0

however some sites are claiming this is a mirrorless lens, as we suggested before it's impossible to tell, and with the extremely short back focus, this sounds like a compact camera lens more than a mirrorless ILC lens.
