Check A Patent™ Vulnerability Analysis

The Service
What Check A Patent™ Delivers
A written Vulnerability Analysis Report identifying exploitable weaknesses in a patent you are evaluating, asserting, licensing, or defending against. Flat fee. Governed by a limited-scope engagement agreement.
Vulnerability Analysis Report
Check A Patent™
Patent Vulnerability Analysis
You provide a U.S. patent number. John Ogilvie reviews the patent and returns a written analysis of exploitable vulnerabilities — gaps in claim scope, enablement weaknesses, claim construction risk, indefiniteness, and other structural weaknesses detectable from the patent itself — so you can use that analysis to evaluate the patent, support a licensing position, or prepare a defense.
This analysis is not a validity search or freedom-to-operate opinion. It is a structural vulnerability analysis based on the patent document itself.
Who This Is For
Three Situations Where Check A Patent™ Is Useful
Accused Infringer
You Received a Demand Letter
Understand the structural weaknesses in the asserted patent before deciding whether to license, challenge, or defend.
Potential Acquirer or Licensee
You Are Evaluating a Patent
Know the exploitable vulnerabilities in a patent you are considering acquiring, licensing, or investing in before you commit.
Patent Owner
You Are Preparing to Assert
Understand the weaknesses in your own patent before licensing negotiations or litigation, so you know what a sophisticated defendant will find.
Before You Buy
Key Terms of the Engagement
These are the most important limitations of this service. Full terms are in the engagement agreement. By clicking BUY you confirm you have read and understood these terms.
Check A Patent™ Vulnerability Analysis
- The report is a structural vulnerability analysis based on the patent document itself — not a prior art search, not a freedom-to-operate opinion, and not a patentability or validity opinion.
- The report does not include prosecution history analysis. It identifies vulnerabilities detectable from the patent document.
- Issued patents cannot be routinely amended. Findings are oriented toward exploitation, evaluation, and defense — not remediation.
- The vulnerability list identifies exploitable weaknesses found. It is not a guarantee that no other vulnerabilities exist.
- This service does not include freedom-to-operate analysis, claim charting, or infringement analysis.
- After delivery, an optional 30-minute follow-up meeting is available via Calendly within a 60-day scheduling window. The meeting is optional, not required.
- Mark all emails to John Ogilvie “PRIVILEGED” to preserve attorney-client privilege.
- You are responsible for all legal deadlines — Ogilvie Law Firm does not determine or monitor deadlines.

Vulnerability Categories
What the Report Looks For
The Check A Patent™ analysis evaluates the submitted patent across multiple structural vulnerability categories, using a proprietary Vulnerability Assessment Table developed and maintained by Attorney Ogilvie. Categories include:
- Claim scope and construction vulnerabilities
- Indefiniteness and claim language ambiguity
- Enablement and written description weaknesses
- Means-plus-function claim risks
- Abstract idea and patent eligibility exposure
- Dependent claim architecture and fallback position gaps
- Specification-to-claim misalignment
- Drawing deficiencies and support gaps
- Priority claim and incorporation-by-reference issues
- Divided infringement vulnerability in method claims
- Fee structure and claim count issues
- Object-of-the-invention and result-guarantee language
Not In Scope
- Prior art search or novelty analysis
- Freedom-to-operate analysis
- Infringement claim charting
- Ownership and chain of title
- Foreign prosecution analysis
- Conduct-based inequitable conduct (absent from the patent file)
