Not having seen the JS patent application, but cockpit air extractors have been in the public domain for a while now. Unless JS has something unique (perhaps the little airfoil in the middle), and unless they filed their patent before selling the first JS1 with an air extractor, JS is not likely to be granted a patent for the air extractor on the JS1c. The JS-3 extracts air out the underside of the fuselage. The JS-3 air extractor is new and I suspect that is what their patent is for.

JS mention of patent application as mentioned on their web site was for the incorporation of airfoil shaped additional element in the outlet area.
