AI IP Assignment Agreement Generator with Blockchain Verification

Why IP Assignment Is the Most Overlooked Startup Legal Step

When a developer writes code for a startup, the default legal rule in most US states is that the developer owns that code — not the company — unless a written IP assignment exists. This is true even if the developer was paid. It is true even if the developer is a co-founder. It is true even if the agreement to assign was verbal.

Venture capital due diligence teams review IP ownership as a condition of investment. If the company cannot prove that all intellectual property used in the business has been legally assigned from every founder, employee, and contractor who touched it, a VC will either require a retroactive assignment negotiation — expensive and time-consuming — or walk away from the deal entirely.

Legal Chain generates IP assignment agreements for every relationship type: founder-to-company assignments that close the gap before fundraising, contractor agreements that assign work product upon payment, and employee IP agreements that cover inventions created during employment. Every completed document is anchored to Ethereum through the Trust Layer. Legal Chain is software, not a law firm. Every IP assignment should be reviewed by a licensed attorney before execution. Legal Chain's Global Lawyer Finder connects you with vetted IP counsel in your jurisdiction at no referral cost.

IP Assignment vs. Work-for-Hire: What Is the Difference

A work-for-hire clause establishes that a work created within the scope of employment or under a specific statutory commission is owned by the employer or commissioning party from the moment of creation — no separate assignment is needed. An IP assignment transfers ownership of already-created IP from the creator to the assignee.

In practice, both provisions should be used together. A contractor agreement should include a work-for-hire clause for all work created under the agreement, and an IP assignment clause as a fallback for any work that does not qualify as work-for-hire under the Copyright Act's enumerated categories. Legal Chain's AI drafts both provisions in a single integrated agreement.

California Exception — Labor Code Section 2870

California Labor Code Section 2870 limits the IP that an employer can require an employee to assign. Inventions developed entirely on the employee's own time, without using company equipment or resources, and unrelated to the company's business, cannot be required to be assigned. Legal Chain's AI surfaces this limitation for California-governed IP agreements so the assignment scope is properly defined. For contractor agreements in California, AB5 classifications affect how the contractor relationship is characterized. Always consult a licensed California IP attorney before executing these agreements.
