Patent filing alerts — USPTO, EPO, and WIPO

Watch any patent office's public filing system for new applications, grants, and assignment changes. Useful for IP attorneys, competitive intelligence teams, and inventors.

Start free trial How it works

WebMonitor.fyi tracks patent office filing portals — USPTO, EPO, WIPO, and national offices — for new applications, grants, abandonments, and assignment changes. The patent filing alerts go to competitive intelligence teams watching competitors' IP activity, IP attorneys monitoring client portfolios and adverse filings, and inventors tracking their own filings through the examination cycle.

What it does

Multi-office coverage

USPTO PAIR, EPO Espacenet, WIPO PatentScope, JPO, KIPO, CNIPA — paste the search URL and the monitor handles the rest.

Competitor and assignee tracking

Watch all filings assigned to a specific company or inventor. Catches new applications, continuations, and reassignments.

IP class and keyword monitoring

Monitor a CPC or IPC class, or a keyword search, to catch any new filings in your technology area regardless of who filed them.

Examination status tracking

Track a specific application through office actions, allowances, and grants — useful for portfolio managers and inventors.

How to set it up

Find the patent office URL

A search-results URL with filters applied, or a specific application's public PAIR / Espacenet page.

Set the criterion

Examples: "Alert me on any new application assigned to [Competitor Inc]." "Notify me when an office action is mailed on this application." "Let me know on any new filings in CPC class H04L 9/0643 from any applicant."

Pick a frequency

Daily checks are usually sufficient; hourly during a competitive product launch window.

Receive alerts

Email or webhook. Webhook into a docketing system is the standard for IP firm workflows.

Common use cases

Track competitor patent filings for competitive intelligence
Monitor a specific inventor's career filings
Watch for adverse filings against client portfolios
Track examination progress on your own pending applications
Catch new filings in a technology area you operate in
Monitor patent reassignments for M&A signal

Honest limits

WebMonitor reads what each patent office publishes publicly. Some pre-publication application data, sealed proceedings, and access-controlled portions of PAIR are outside scope. Publication cycles vary by office — USPTO publishes most applications 18 months after filing, so applications in the first 18 months are not visible to anyone without access to the private record.

Frequently asked questions

Can I monitor USPTO PAIR for a specific application?

Yes. The public PAIR page for an application is a standard URL you can paste into a monitor. Office actions, responses, and examiner correspondence trigger alerts as they post.

Does this work for international filings?

Yes. EPO Espacenet, WIPO PatentScope, JPO, KIPO, and CNIPA are all supported. Each office's public search URL works as a monitor source.

Can I track filings by CPC class?

Yes. Run an EPO Espacenet or USPTO search filtered by class and set the monitor on the search results URL. New filings matching the class trigger alerts.

How does this compare to commercial patent intelligence platforms?

Platforms like Patsnap, Innography, and Derwent add ML-based analytics, family tree visualizations, and curated taxonomies. WebMonitor is a real-time alerting layer on top of the public filing system — cheaper, faster to set up, and complementary to a full IP intelligence platform.
