Example of Proper Usage:

  • 'US Patent D0974555 Endoscope operating unit' → 'Patent Number' → 'D0974555' is correct. Note that the Patent Number may be labeled as "Patent No." and is almost always in the top right corner of the first page of the patent document. The Patent Number should be listed without the preceding "US" and without the commas that often appear in the patent document.

Example of Improper Usage:

  • 'US Patent D0974555 Endoscope operating unit' → 'Patent Number' → '29705600' is incorrect because it is the Patent Application Number. The Patent Number may be labeled as "Patent No." and is almost always in the top right corner of the first page of the patent document. The Patent Number should be listed without the preceding "US" and without the commas that often appear in the patent document.

  • 'US Patent 20210007540 Capsules, Beverage Brewing Systems And Fabrics With Optimum Filtration Characteristics' → 'Patent Number' → '20210007540' is incorrect. The citation document does not contain a Patent Number. The document contains a publication number instead. Unlike patent numbers, publication numbers are preceded by Pub. No. And unlike patent numbers, publication numbers' first four characters typically indicate a year from the past century.
