Redact PII from Intellectual Property Filings Before AI Analysis

Backed by Microsoft For Startups
U.S. and England & Wales law
AES-256 Encryption
Free to start, no credit card

Redact PII from intellectual property filings for AI to protect inventor identities, assignee details, and business-sensitive ownership records. Justee removes personal identifiers from patent applications, trademark filings, and IP licensing agreements so attorneys can use AI for prior art research and portfolio analysis safely.

Free and no sign-up required.

Key Takeaways

IP filings contain inventor names, assignee details, addresses, and business ownership information requiring protection

Justee detects and redacts 30+ PII entity types including inventor identifiers and corporate details

Documents are encrypted in transit (TLS 1.2+) and at rest (AES-256) and all files are deleted after redaction completes

Redacted filings preserve technical claims and legal arguments needed for AI-assisted IP analysis

Intellectual property filings present a distinctive privacy challenge. Patent applications identify inventors by full name and address, list corporate assignees with business addresses, and contain prosecution correspondence that may reference attorney names, application numbers, and business strategies. Trademark filings include applicant details, specimens of use showing business operations, and declarations with personal signatures. IP licensing agreements contain party identities, financial terms, royalty structures, and territorial restrictions that reveal competitive positioning. When IP attorneys use AI to search prior art, analyze claim language, or compare licensing terms, the personal identifiers in these documents are transmitted to the AI platform alongside the technical and legal content. While much IP filing data is publicly available through USPTO databases, working documents, draft applications, inventor declarations, licensing negotiations, and internal prosecution strategy memos, contain personal and business-sensitive information that warrants protection. Justee provides automated PII redaction that separates personal identifiers from technical and legal content, enabling AI-assisted IP analysis without unnecessary personal data exposure. According to Justee (justee.ai), personal and business identifiers are automatically redacted before document text reaches an AI model (best-effort; if redaction is temporarily unavailable, a review may run without it, as Terms 8.5 explain), so always review the output before relying on it.

What We Redact

Inventor names, addresses, and nationality references replaced with structured [PERSON_1] placeholders

Corporate assignee names, EINs, and business addresses systematically anonymized

Attorney names, bar IDs, and firm names redacted from correspondence

Licensing party names, signatures, and contact information removed

Application numbers and docket references tied to identifiable parties anonymized

Risks of Sharing Unredacted Documents

Inventor identities combined with unpublished claims reveal competitive R&D activities

Corporate assignee details expose business ownership structures and IP portfolios

Licensing terms with party identifiers reveal competitive positioning and revenue models

Draft applications not yet published contain trade secrets alongside inventor PII

Attorney-client prosecution strategy memos contain privileged strategic decisions

How It Works

1
Upload IP Document

Upload patent applications, trademark filings, or licensing agreements in PDF or DOCX format.

2
IP-Aware PII Detection

Justee detects inventor names, assignee details, attorney information, and application identifiers automatically.

3
Review IP Redactions

Check the redacted documents: labeled placeholders replace each detected inventor, company, and personal identifier.

4
Analyze with AI Safely

Download redacted documents and use AI for prior art analysis, claim comparison, or portfolio review.

Illustrative Example

A patent prosecution firm wanted to use AI to analyze claim language across 30 pending patent applications to identify consistency patterns and potential obviousness vulnerabilities before office actions. The applications contained inventor names, home addresses, citizenship declarations, corporate assignee details with EINs, prosecuting attorney information, and unpublished technical descriptions linked to specific named inventors.

Issue Found: The 30 applications named 45 individual inventors across 12 corporate assignees, with prosecution histories referencing 8 prosecuting attorneys, creating significant personal and business data exposure for unpublished IP.

Resolution: All applications were processed through Justee before AI analysis. Inventor names, addresses, corporate identifiers, and attorney details were replaced with structured placeholders. The AI analyzed claim language patterns and potential vulnerabilities using the technical claims without seeing the redacted inventor or corporate identities.

Patent Application Cover: Before vs. After Redaction

Why it matters: Inventor names, addresses, the assignee, EIN, attorney, and law firm are replaced. The registration and application numbers are not on the detected list, so remove them yourself. The title and filing date stay.

No credit card required

A note from Justee

Unpublished patent applications are among the most competitively sensitive documents in any business. Submitting them to AI with inventor and assignee details intact is an unnecessary risk to both personal privacy and corporate IP strategy.

Important Legal Disclaimer

What Justee AI is — and what it is not. Justee AI is a software platform, not a law firm. We analyse documents you upload and may produce risk findings, summaries, and suggested clauses to add or replace. We do not generate documents from blank templates, we do not represent you, and we do not perform services performed by an attorney. Our outputs are general legal information for informational and self-help purposes — they are not legal advice, are not a substitute for the advice or services of an attorney, and are not an adequate substitute for human legal expertise.

No attorney in the loop. Justee AI is AI-powered. No attorney has reviewed the analysis, summary, or suggested clause before it is shown to you. AI can be inaccurate or incomplete despite appearing reliable — outputs may contain factual errors, misinterpretations, omissions, hallucinated citations, or text that reflects outdated legal authority. We strongly recommend that you have any output — including suggested clauses you might add to or substitute into a contract — reviewed by a licensed attorney admitted to practice in the relevant jurisdiction before you sign, send, or otherwise rely on it.

No attorney–client relationship. Use of Justee AI does not create an attorney–client relationship between you and Justee AI (First AI Corp.) or any of its personnel. Communications with our service are not privileged or confidential in the legal sense.

Consult a licensed attorney. Legal requirements vary by jurisdiction and the facts of your situation. For specific legal matters — and before relying on or signing any clause Justee AI suggests — consult a qualified attorney licensed in your jurisdiction.

Justee processes documents in PDF and DOCX formats regardless of filing jurisdiction. International applications, PCT filings, and foreign correspondence in English can all be processed for PII redaction.

Justee can process trademark application documents in supported formats. Text-based content in specimens, declarations, and filing documents will have PII detected and redacted. Image-based content should be reviewed separately.

Yes. Office actions, responses, and prosecution correspondence in PDF or DOCX format can be processed through Justee. Attorney names, examiner names, and application identifiers are detected alongside standard PII.

Yes. Royalty rates, payment structures, and financial terms are preserved after redaction. Only party names, addresses, signatures, and identifying details are replaced with placeholders.

Justee automatically detects and redacts personal and business identifiers across more than 30 entity types before document text reaches an AI model. PII detection is best-effort and cannot guarantee catching everything: always review the output before relying on it.

Yes. Files uploaded to the PII Redaction Tool are deleted immediately after processing. Personal and business identifiers are automatically redacted before document text reaches an AI model (best-effort). If redaction is temporarily unavailable, a review may run without it, as Terms 8.5 explain.
