Overview

Returns a paginated list of trademarks an attorney has prosecuted, scoped automatically to the parent attorney. Use this for attorney portfolio views, client roster auditing, or competitive intelligence on prosecution counsel. Results are always sorted by -filing_date (newest first). Every Appendix A filter from the main List Trademarks endpoint is available here. Arrays are comma-separated, date ranges use flat _gte / _lt operators, and booleans must be the literal strings true or false.
