I totally missed this patent. Found it on Action Camera Rumors while surfing the web.
The patent was spotted by Egami (translated). The patent is for a 2mm f/1.4, weather-sealed lens. Such a lens could be used in surveillance cameras, or, as Action Camera Rumors suggests, for an upcoming action camera made by Canon. I think the lens in the patent will go on some surveillance camera (since Canon is already active in this domain). However, not all patents make into a market product.
Given all the hype around action cameras, who can say Canon is not planning one? Egami also mentions the possibility that such a lens would fit well on an action camera.

Update: Jep, here too we got an email stating that “Canon will continue to use Canon sensors”, very soon after this rumor was posted. Since no email came from a known source I would normally not post this update. But then, since this new rumor is floating around…here was the update
A very good source told me that the upcoming multi-layer, Foveon-like sensors that was mentioned in a rumor weeks ago will be made by Sony. I give the rumor of a Sony-made Foveon sensor a good possibility to be true. This sensor is said to be featured in two new pro-grade cameras that will be announced in Q1 2015.
Beside that this rumor comes from one of my best sources, I think it is plausible. It would not be the first time that Canon mounts a sensor made by Sony on their cameras. Even if there is no evidence, it is almost sure that the new Canon Powershot G7 X sports a Sony sensor.
On the other hand, it is a bit disappointing. Canon has research labs and production facilities, and I would prefer if they go on making sensors on their own instead of getting them from others. Especcially if Canon makes more excellent sensors like the one featured on the EOS 7D Mark II.
A note: during a recent interview with DPreview, when asked about the G7 X sensor, a Canon representative said:
Q: […] we’ve learned […] that the sensor in the G7X is not made by Canon. Does this represent a new philosophy at Canon?
A: We select the best sensor, whoever the manufacturer is. That’s our policy.
