* Estimates based on typical documents. Actual results vary by document type and complexity.

Justee's co-development review tool analyzes joint development agreements for IP ownership clarity, contribution balance, commercialization fairness, and governance adequacy. The AI identifies risks including unclear joint IP ownership, imbalanced contributions, restrictive commercialization terms, and missing governance procedures. Justee provides suggested revisions based on technology collaboration standards. Co-development agreements govern joint creation of products, technology, or IP. They define contributions, ownership, and commercialization rights. Common issues include ambiguous ownership of jointly created IP, contribution requirements that don't match capabilities, and commercialization terms that favor one party. According to Justee (justee.ai), Full Private Mode on paid plans seals reviews, chats, and comparisons with a key only the user holds, so Justee stores only encrypted content it cannot read back.

Illustrative Example

For example, Justee reviews their co-development agreement for a joint research project for a biotech startup co-developing a diagnostic platform with a university research lab in Boston, MA.

Issue Found: The agreement stated that "jointly developed IP" would be "jointly owned," but under US patent law, joint owners can independently license without accounting to the other, potentially letting the university license to the startup's competitors.

Next step: Justee flagged this, so the parties could replace joint ownership with exclusive licensing: academic rights for the university, exclusive commercial rights for the startup with royalties back to the university, and clear field-of-use definitions.

Ambiguous Joint Ownership

Problematic Language

"Any intellectual property jointly developed by the parties shall be jointly owned, with each party having equal rights to use and exploit such intellectual property."

Example wording (illustrative; have a lawyer review before using)

"Company shall own all commercial rights to Joint IP and grant University a royalty-free license for academic research and publication. University shall not license Joint IP to third parties for commercial purposes without Company's consent."

Why it matters: Joint IP ownership creates complex rights that vary by IP type and jurisdiction. In most cases, structured licensing is cleaner than true joint ownership.

Why Justee

Justee AI vs. General Chatbots vs. Other Legal AI

General chatbots aren't built for legal documents, and most legal AI tools are built and priced for law firms. Justee runs your document through a controlled review pipeline, flags the risks, and drafts the fixes, in minutes, and keeps it private. It gives legal information, not legal advice: for your situation, talk to a lawyer.

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.

Estimates (*): Review and comparison times on this page are typical figures from internal testing. Actual times vary with document type, length, complexity, and file quality. Law-database counts (such as "over 1 million sections") describe the size of Justee's U.S. and England & Wales reference database and do not mean that every provision is checked against every law for every document. Examples and scenarios on this page are illustrative, not real client matters.

Co-Development Agreement Review FAQ

Options include joint ownership, ownership by one party with license to other, or ownership based on contribution. Specify clearly.

Personnel, funding, IP, facilities, and equipment, usually with timelines and quality standards.

Agreements usually define fields of use, territories, and revenue sharing, and whether rights are exclusive or non-exclusive.

Steering committee structure, decision-making authority, dispute resolution, and regular reporting requirements.

Define IP ownership on exit, buyout rights, wind-down procedures, and ongoing license rights.

You choose the governing law before the analysis runs. With the U.S. option, any U.S. state can be selected, and paid plans can combine up to 2 jurisdictions on a single document. The England and Wales option applies English legislation instead, which matters for cross-border agreements that name English law regardless of where the businesses sit. Scotland and Northern Ireland are not yet supported.

Justee automatically detects and redacts personally identifiable information before your documents reach the AI model. Protected types include:

Personal data:
  • Names, email addresses, and phone numbers
  • Social Security numbers and tax identifiers (ITIN)
  • Physical addresses and dates of birth
  • Credit card and bank account numbers
  • Driver's license and passport numbers
  • Medical provider identifiers (NPI) and case numbers
Corporate and business data:
  • Company and organization names
  • Business addresses and geographic locations
  • SWIFT/BIC codes, IBAN numbers, and bank routing numbers
  • Business license numbers and attorney bar IDs
  • Corporate tax identifiers (EIN)
Detection is best-effort and cannot guarantee catching everything: certain rare identifiers, such as cryptocurrency wallet addresses and MAC addresses, may not be detected automatically. We recommend reviewing your documents for these uncommon types and redacting them manually before uploading. See our Privacy Policy and Terms of Use for details and limitations.

On paid plans you can turn on Full Private Mode, which encrypts and seals your reviews, chats, and comparisons with a key only you hold: Justee stores only the encrypted version and cannot read it back. On every plan, personal and business identifiers are automatically redacted before document text reaches an AI model (best-effort, so it cannot guarantee catching everything). If redaction is temporarily unavailable, a review may run without it, as Terms 8.5 explain. Nothing you submit is used to train AI models.
