Invention Assignment Agreement Template

In plain language: Establishes precise meanings for key terms — 'Invention,' 'Confidential Information,' 'Company Business,' and 'Related Fields' — to set the boundaries of what is and is not assigned.

Common mistake: Defining 'Invention' so broadly it sweeps in work the employee did entirely outside work hours, unrelated to the company's business — courts in several jurisdictions void overbroad assignments and may void the entire clause.

In plain language: The core operative clause: transfers all right, title, and interest in covered inventions to the company, including patent rights, copyright, trade secrets, and all related IP, effective at the moment of creation.

Common mistake: Omitting the phrase 'and all related worldwide patent rights, copyrights, trade secrets, and other intellectual property rights.' Without this language, the assignment may not transfer foreign IP rights, leaving gaps for internationally active companies.

In plain language: Requires the signer to list all inventions they conceived before the engagement and want excluded from the assignment — anything not listed is presumed assigned to the company.

Common mistake: Leaving Schedule A blank rather than explicitly listing 'None.' A blank schedule creates ambiguity — the employee may later claim they intended to list prior inventions but forgot, creating a disputed carve-out.

In plain language: Requires the employee or contractor to promptly report all inventions covered by the agreement to a designated company representative, enabling the company to assess ownership and file patents before public disclosure.

Common mistake: Setting a disclosure window of 30 days but not specifying the recipient or format. Vague disclosure obligations go unfulfilled — name a specific role (e.g., General Counsel or CTO) and require a written summary.

In plain language: Acknowledges that all copyrightable works created within the scope of employment are 'works made for hire' under the Copyright Act, owned by the company from creation — and adds an assignment as a fallback in jurisdictions or situations where the doctrine does not apply automatically.

Common mistake: Relying solely on the work-made-for-hire doctrine without a backup assignment clause. Independent contractors do not create works made for hire under US law for most categories of work — explicit assignment is required.

In plain language: Requires the signer to cooperate in executing patent applications and IP transfer documents after termination, and grants the company a limited power of attorney to act on their behalf if they are unavailable or uncooperative.

Common mistake: Omitting the power of attorney entirely. If a former employee is unreachable or hostile, the company cannot execute a patent assignment without this clause, which can delay or block a patent prosecution.

In plain language: Prohibits the signer from disclosing or using the company's confidential information — trade secrets, product roadmaps, customer data, financials — during and after the engagement.

Common mistake: Setting the same survival period for trade secrets and general confidential information. Trade secret protection has no expiration under the Defend Trade Secrets Act and most state laws — a fixed expiration for trade secrets can inadvertently limit protection.

In plain language: In jurisdictions that recognize moral rights (Canada, UK, EU), the signer waives the right to be identified as creator and to object to modifications — enabling the company to freely commercialize and adapt the IP.

Common mistake: Omitting the moral rights waiver from agreements with employees or contractors in Canada, the UK, or the EU. Moral rights survive assignment in those jurisdictions and can prevent the company from modifying or sublicensing the work without the creator's consent.

In plain language: Limits the assignment to comply with state and provincial statutes that protect employees' rights to inventions made entirely on their own time, with their own resources, and unrelated to the company's business.

Common mistake: Omitting the statutory carve-out language for California, Delaware, Illinois, Minnesota, North Carolina, or Washington employees. Assignments that violate these statutes are void in those states — not narrowed, void — potentially eliminating the entire clause.

In plain language: Specifies the jurisdiction whose law governs the agreement and the forum for resolving disputes — typically the company's home state or province, with arbitration for efficiency.

Common mistake: Choosing a governing law state that has no employment connection to where the employee works. California courts, for example, apply California law to protect California employees regardless of a contrary choice-of-law clause.

An invention assignment agreement is a contract in which an employee, contractor, or founder transfers ownership of any inventions, patents, software, and related intellectual property they create in connection with their work to the company. It ensures the company — not the individual — holds clear legal title to all IP that underpins the business, which is essential for raising investment, prosecuting patents, and commercializing products.

No federal US law requires a standalone invention assignment agreement, but without one the company may not automatically own IP created by employees — and almost certainly does not own IP created by independent contractors. Investors and acquirers treat a missing or unsigned agreement as a material title defect that must be remedied before closing. Many employment contracts include invention assignment clauses, but a standalone agreement provides stronger, cleaner documentation.

An NDA (non-disclosure agreement) prohibits a party from sharing confidential information — it protects secrecy but does not transfer IP ownership. An invention assignment agreement transfers ownership of inventions and IP to the company. The two obligations are complementary and often appear in the same document or in companion agreements signed at onboarding. An NDA alone does not give the company ownership of anything the employee creates.

Yes. A properly drafted agreement covers software, source code, algorithms, database schemas, and related documentation as both copyrightable works and potentially patentable inventions. The work-made-for-hire doctrine provides a copyright basis for employee-written code, but an explicit assignment clause is required for contractor-written code and as a fallback for employee code where the doctrine is disputed.

Yes — the statutory carve-out in California, Delaware, Illinois, Minnesota, North Carolina, and Washington protects inventions made entirely on the employee's own time, using no company resources, and unrelated to the company's business or anticipated R&D. Employees in those states retain rights to qualifying personal inventions regardless of what the contract says. Outside those states, employees typically retain only inventions they explicitly list on the prior inventions schedule before signing.

The agreement must be signed before or on the employee's or contractor's first day of work. In common-law jurisdictions — including the US, Canada, and the UK — a contract signed after the start of employment may lack fresh consideration, which can render the IP assignment and any restrictive covenants unenforceable. If a company discovers unsigned agreements after onboarding, it should provide documented additional consideration when obtaining the late signature.

No — prior inventions are carved out and listed on a Schedule A attached to the agreement. The employee or contractor discloses inventions they conceived before the engagement that they want to retain. Anything not listed on Schedule A is generally presumed to fall within the assignment scope, which is why it is critical for the signer to complete Schedule A carefully and for the company to review it for potential conflicts with its core technology.

An IP assignment clause embedded in an employment contract provides substantial protection, but a standalone invention assignment agreement has advantages: it is more detailed, it includes the prior inventions schedule as an integrated exhibit, it covers contractors and founders who are not employees, and it survives termination of the employment relationship as an independent document. For companies with significant IP value, a standalone agreement is the more defensible approach.

Properly executed invention assignment agreements run with the IP — meaning ownership transfers automatically to the acquirer as part of the acquisition. The acquiring company will conduct IP due diligence to confirm that every employee and contractor who worked on core technology has a signed agreement on file. Missing agreements are one of the most common issues that delay or reprice M&A transactions, sometimes requiring the target to obtain retroactive signatures before closing.
