\nData in this report is sourced from IP Pilot and is accurate as of May 2026 and is based on the number of patent filings first published between 2021 and 2025. Because patent data may be subject to reporting delays in public databases, figures may fluctuate over time.<\/i><\/p>\n<\/blockquote>\n
Patent filings in the United States demonstrated robust, if gradually declining, activity between 2021 and 2025, reflecting both the enduring strength of the world’s largest IP market and broader macroeconomic pressures that reshaped filing volumes across the period. Over these five years, the USPTO received hundreds of thousands of applications handled by more than a thousand law firms. The top 25 firms alone accounted for a substantial share of all filings (498,451 or 22%)<\/b>, underscoring the concentration of patent prosecution activity among a relatively small group of specialist and full-service IP practices.<\/p>\n
The data used in this report was sourced from IP Pilot, an IP intelligence platform for law firms that analyzes agents, clients, and their relationships.
