What he built on, and who built on him
Every citation recorded on Meyer’s filings, in both directions. The left column is what the patent offices held his claims against. The right is the one worth reading: it is not who agreed with him, it is who had to say his work came first.
4 of the citing records are not patents — they are documents already in the archive, such as the Energy of the Future newsletters, that cite his filings. They carry no patent number, so there is no office record to link them to.
Who built on him
Assignees named on the most filings that cite Meyer, counted in filings rather than citations — a patent naming six of his is one company working the same ground, not six.

A citation is a claim made on a patent-office record, not an endorsement — most of the filings on the right cite Meyer because an examiner made them. Numbers link to the office’s own record; titles link to what this archive holds.
