In specific cases, patent applicants and holders may claim copyright in portions of those documents. In those specific cases, applicants are required to identify the portions that are protected under copyright, and are additionally required to state the following within the body of the application and patent (see 37 CFR 1.71(d) & (e) and 37 CFR 1.84(s), and MPEP § 608.01(e) & (w) and MPEP § 1512):
A portion of the disclosure of this patent document contains material which is subject to (copyright or mask work) protection. The (copyright or mask work) owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all (copyright or mask work) rights whatsoever.
The original patent should be checked for the presence of such language before an assumption is made that the contents are in the public domain. (This template can be replaced by {{PD-US-patent-no notice}} in such cases.)
If necessary or requested, other licencing terms can get discussed.

Additional information:
The mentioned licence on my media is exclusively valid for the version and resolution up to the shown on Wikimedia Commons. Any other version of the shown media or higher resolution optionally available on another website is not included in this licencing and not allowed for free use.
The values of focal length and aperture in the metadata need to be read with precaution!
I'm still using older manual focused lenses therefore lens data has to be changed on the camera manually when changing the lens. This may be forgotten sometimes. The 28 mm shift lens aperture is not assigned – by 3.5 is always displayed the largest aperture.
