  • Doesn’t look like a number from any patent system I’m familiar with. Do you have any other information?

I do not think that number leads to anything, but the company that is mentioned in the article that attributed that number to them does have a published US patent application. It is Methods And Apparatuses For Harvesting Water From Air 2020/0298174. https://patents.google.com/patent/US20200298174A1/en

  • Good idea to search on the company name. Might also want to link to their website.

  • The number of OP looks like an internal reference of the IP firm handling the case, which cannot lead to anything as you said. Commented Jun 22, 2021 at 8:14
