Monitor Patent Filings by a Specific Company or Technology Area

Patent filings are a leading indicator of R&D investment. A company that files 15 patents covering a specific technology area has made a decision to invest in that area — typically 12–24 months before a product ships. For competitive intelligence, investment research, and M&A due diligence, patent monitoring provides signals that don't appear in any other public data source.

The Free Option: USPTO Patent Full-Text Database

The USPTO provides free public access to patent applications and grants via their patent full-text database and PatentsView. Google Patents aggregates USPTO and international patent data in a searchable interface. Both are free and comprehensive, but neither offers email alerts or continuous monitoring — you have to check manually.

Patent Alert Services

Lens.org: A free, open-source patent database covering USPTO, EPO, and WIPO filings. Offers email alerts for searches covering specific assignees, inventors, or technology classifications (CPC/IPC codes). Free and surprisingly comprehensive — a good starting point before committing to paid tools.

Google Patents email alerts: Set up via Google Scholar alerts targeting the patent database. Less reliable than dedicated tools but costs nothing.

Derwent Innovation, Clarivate, PatSnap: Enterprise patent analytics platforms with robust monitoring, categorisation, and competitive landscaping features. Priced for IP teams and law firms — typically thousands per year.

AI Topic Monitoring for Patent Landscape Coverage

AyeWatch topic monitoring adds coverage of the reported patent landscape: trade press coverage of significant filings, patent litigation news, USPTO policy changes, and technology area analysis. A topic like "[Company] new patent filings and IP strategy developments" catches patent news as it's covered by IP law publications, tech press, and analyst reports — the contextual layer that raw patent databases don't provide.
