PATENT INTELLIGENCE
Patent Intelligence & IP Tracking Software
Patent analysts waste hours every week checking USPTO Patent Center, Google Patents, and competitor filings by hand. Changeflow watches every patent office, competitor IP page, and docket in parallel and filters to only the filings that matter to your portfolio.
Trusted by IP teams at regulated-industry companies
The patent intelligence layer Anaqua and PatSnap don't give you
Legacy patent platforms cost $30K-150K/year and still leave analysts manually checking competitor IP pages, licensing announcements, and examiner docket updates. Changeflow plugs those gaps with AI-filtered tracking across USPTO, EPO, WIPO, and any competitor page you define. From $99/mo. Works alongside your existing IP suite.
- ✓ Track USPTO Patent Center dockets, EPO register, and WIPO PCT filings in one feed
- ✓ AI filters to your technology areas and key competitors. Skip the irrelevant grants
- ✓ Catch competitor announcements the patent databases miss: newsroom posts, R&D blog updates, product specs
- ✓ From $99/mo billed annually. Not $30K+/year like PatSnap or Anaqua
- ✓ 60-second setup. Paste a URL, describe what you care about. Done
The Changeflow advantage for IP research
IP-aware AI
Our AI understands patent claim language, continuation families, reassignments, and prosecution status. It filters by CPC code, assignee, technology area, or plain-English brief.
Natural language setup
No CSS selectors. Tell us: 'Track USPTO grants assigned to Moderna in mRNA delivery CPC codes'. We handle the rest.
Claim-level summaries
Don't read full specifications. Get AI-generated summaries of what a new grant covers, how it differs from related filings, and why it matters to your portfolio.
Global office coverage
Track USPTO, EPO, WIPO, JPO, KIPO, CNIPA, and UKIPO in one feed. Works with PDFs, XML registers, and HTML dockets alike.
Self-healing monitoring
When a patent office redesigns Patent Center or an EPO register page, Changeflow adapts automatically. No broken alerts. No missed grants.
Advanced anti-blocking
Patent office sites are notoriously aggressive about scraping. Our anti-blocking stack keeps tracking reliable where Distill and Visualping get locked out.
Optimized for the patent sources you need to track
Changeflow has been tested on the patent offices and competitor IP pages analysts check most. Our AI understands the structure and terminology of these sources, so alerts are accurate and rarely trigger on noise.

How IP teams use Changeflow
Competitor patent surveillance
IP counsel & patent analysts at pharma, biotech, and tech companies
Challenge: Checking 30+ competitor assignees across USPTO, EPO, and WIPO by hand costs analysts 8-10 hours a week and still misses continuations filed under subsidiaries
Solution: Set one prompt per competitor family: 'Track USPTO and EPO filings assigned to AstraZeneca subsidiaries in oncology CPC A61K'. AI catches reassignments and continuations automatically.
Outcome: Cut weekly surveillance time from 10 hours to 30 minutes. Spot competitor pivots weeks earlier.
A biotech IP team tracking 42 competitor assignees reduced analyst hours by 85% while catching 3 high-priority continuations the prior tool missed.
Freedom-to-operate monitoring
R&D teams & patent attorneys at product companies
Challenge: Freedom-to-operate searches go stale within weeks. New grants and continuations in your technology space can surface AFTER product launch if nobody's watching
Solution: Define your product's technology area with a plain-English brief. Changeflow watches USPTO, EPO, and WIPO for new filings that touch your FTO scope and sends claim-level summaries.
Outcome: Catch FTO-relevant grants within days of publication, not months. Reduce launch risk without hiring another analyst.
A medical device company avoided a potential infringement claim by catching a competitor's continuation within 48 hours of USPTO grant.
Licensing & M&A due diligence
IP strategy teams & transactional attorneys
Challenge: Tracking patent status, oppositions, and examiner actions across a diligence target's global portfolio is slow and error-prone with PAIR lookups
Solution: Point Changeflow at the target's assignee dockets across USPTO, EPO, and JPO. Get a live feed of office actions, oppositions, and reassignments during diligence.
Outcome: Stay current on portfolio health throughout a 60-90 day diligence window without daily manual docket checks.
An M&A team ran parallel tracks on 7 target companies' USPTO and EPO dockets, catching an EPO opposition filed mid-diligence that shifted deal terms.

Frequently asked questions
If you can't find what you're looking for, email our support team and we'll get back to you with answers quickly.
-
Which patent offices does Changeflow track?
USPTO (Patent Center, PAIR, PTAB, Patent Gazette), EPO Register, WIPO PCT Patentscope, JPO, KIPO, CNIPA, and UKIPO are all optimized. We've also tracked Canadian Intellectual Property Office, IP Australia, and Rospatent for clients. If a patent office is online, Changeflow can track it.
-
Can I filter by CPC code or assignee?
Yes. Write a plain-English brief like 'Track USPTO grants in CPC A61K assigned to Moderna or its subsidiaries' and the AI handles CPC matching, assignee families, and reassignments. No Boolean query writing required.
-
How is this different from PatSnap or Anaqua?
Three things. Price: $99/mo vs $30K-150K/year. Coverage: we track any competitor web page alongside patent offices, not just patent databases. Setup: 60 seconds vs weeks of onboarding. Changeflow is built for teams who want useful alerts now, not an enterprise platform rollout.
-
Does Changeflow replace my existing patent platform?
Often it sits alongside. Teams keep PatSnap or Derwent for deep analytics and use Changeflow for daily surveillance, competitor page tracking, and custom sources the big platforms don't ingest. Some mid-market teams replace their enterprise tool entirely.
-
Can I track competitor IP pages, not just patent offices?
Yes. That's one of the biggest gaps in traditional patent tools. Paste any competitor's press release page, investor relations site, or R&D blog and Changeflow watches for licensing announcements, litigation news, and new product IP disclosures.
-
How does Changeflow handle PDF patent documents?
Our AI extracts and analyzes text from patent PDFs including grants, published applications, office actions, and opposition filings. It detects substantive changes in claims, specifications, and examiner actions.
-
What about continuations and reassignments?
The AI tracks assignee families and continuation relationships. If a subsidiary files a continuation or a patent gets reassigned to a new entity, it flags the change with context.
-
How quickly are new USPTO grants detected?
Set check frequency as often as hourly. Most clients run daily checks on USPTO and catch new grants within hours of publication in the weekly Patent Gazette.
-
Can I use this for FTO searching?
Yes, but as a continuous layer on top of your initial FTO search, not a replacement for it. Run a proper FTO search at launch, then use Changeflow to track new filings in your technology space so the FTO doesn't go stale.
-
Does it work for international patents?
Yes. EPO, WIPO PCT, JPO, KIPO, CNIPA, UKIPO, IP Australia, and Canadian IPO are all supported. The AI handles multi-language patent content where translations are available.
