They describe the procedure in Science.

Did they patent the method? I can't find anything on Kaners Google Scholar page, but maybe somebody knows more.

Essentially, can we start a business and sell graphene based on their method?

  • didn't know it exists. And yes, I found it on a coauthors page.

Yes they did: United States Patent Application 61/606,637

  • That is the number of a provisional application. If that is all there is it is not patented yet and there is no way to tell if a patent will ever issue.

  • Can this provisional application be viewed? I tried to search for patents, but I'm unable to figure out where to enter what.

  • Should work on Public PAIR portal.uspto.gov/pair/PublicPair however it is typically Government-issued-bureaucratically finicky and requires numbers to be entered by some incomprehensible logic for commas, slashes, etc - I couldn't find it by this application number.

  • I confirm it's not findable... How demotivating.

  • As I said, it is a provisional application. They are not ever technically "published" but do become viewable if a non-provisional application associated with them is published or results in a granted patent. The 61/ series is what lets you know it is a provisional application. Even a non-provisional application might not be published for 18 months from its earliest priority date.
