Lists use firm counsel-of-record links on U.S. granted patents that have CPC codes. Pending applications without a grant usually lack CPC and are omitted. Solo practitioners appear on attorney rankings, not firm rankings.

Decision support only — not legal advice, not a directory of “best lawyers,” and not an endorsement. Calculated statistics cannot be edited by the attorney or firm.
