Patent & Trademark Management platforms manage the lifecycle of intellectual property portfolios — tracking patent and trademark prosecution, maintenance deadlines, annuity payments, and portfolio-level analytics across jurisdictions. Core capabilities include patent and trademark docketing, prosecution workflow management, annuity and maintenance fee tracking with payment automation, portfolio dashboards and reporting, inventor and assignee management, jurisdiction-specific deadline calendaring, and integration with patent offices (USPTO, EPO, WIPO) and outside counsel. The category spans enterprise IP management platforms (Anaqua, CPA Global/Clarivate, Dennemeyer, IPfolio) and mid-market tools (Alt Legal, TM Cloud) focusing on trademark docketing.
