'US Patent D0974555 Endoscope operating unit' → 'Date of Patent' → 'September 13, 2019' is incorrect because it is the Filed Date. The Date of Patent is almost always listed in the top right corner of the first page of the patent document underneath the Patent Number.

'US Patent 20210007540 Capsules, Beverage Brewing Systems And Fabrics With Optimum Filtration Characteristics' → 'Date of Patent' → 'January 14, 2021' is incorrect.
