Employee Invention Assignment in Alabama

Can an Alabama employer require assignment of every invention?

Because there is no statute on point, the limits come from general principles rather than a legislative carve-out. A full-text review of the Code of Alabama 1975 surfaces no employee-invention-, patent-, or intellectual-property-assignment provision; the employment-adjacent statutes in Title 8 are the Restrictive Covenant Act (Ala. Code §§ 8-1-190 to 8-1-197) and the Alabama Trade Secrets Act (Ala. Code §§ 8-27-1 to 8-27-6), and neither addresses what an invention-assignment clause may capture. An Alabama employer therefore starts from contract law, not a § 2870-style statutory ceiling on what an assignment promise may reach.

The closest Alabama Supreme Court authority is Gilley v. Southern Research Institute. The court was not asked to decide who owns an employee invention by default — the case litigated only the employee's compensation under the employer's royalty-sharing policy — but it took the employment contract's broad invention-ownership clause as the operative source of the employer's rights A.1.

“When he was hired by SRI in 1979, Gilley executed a contract acknowledging that any ‘improvements, inventions and discoveries’ made by him during the tenure of his employment would ‘be the sole and exclusive property of [SRI].’”

The substantive default that Alabama contract law operates against is the federal patent premise restated in Stanford v. Roche: absent an effective assignment, rights in an invention belong to the person who conceived it A.2.

“Since 1790, the patent law has operated on the premise that rights in an invention belong to the inventor.”

The practical consequence is that an Alabama employer can, in principle, contract for assignment more broadly than a California or Washington employer, because no statute carves out own-time inventions from the reach of the clause. But that breadth is not unlimited: an assignment clause is still an ordinary contract term, subject to general contract-law defenses, and to the extent it operates as a restraint on the former employee it runs into Alabama's anti-restraint regime discussed below. There is simply no statutory own-time/own-resource safe harbor for the employee to invoke and no statutory ceiling for the drafter to code around.

Must an Alabama employer notify the employee?

There is nothing to give notice of. A notice requirement exists in California and Washington precisely to alert the employee to a statutory own-time carve-out that limits the assignment; Alabama has enacted no such carve-out, so there is no statutory line for a notice to mark. This is why the entry is marked not applicable rather than a bare no: the question presupposes a statutory carve-out that Alabama does not have.

Where an Alabama employee owes invention-ownership obligations, they come from the contract, not a statute. In Gilley v. Southern Research Institute, the Supreme Court of Alabama resolved an employee-invention compensation dispute entirely on the employment contract and the employer's policy documents, treating the contractual ownership clause as the source of the employer's rights B.1.

“When he was hired by SRI in 1979, Gilley executed a contract acknowledging that any ‘improvements, inventions and discoveries’ made by him during the tenure of his employment would ‘be the sole and exclusive property of [SRI].’”

For a multistate employer the takeaway is the inverse of the notice states: an Alabama employer neither has to give a § 2872-style notice nor can rely on one to cure an overbroad clause. The enforceability of the assignment turns entirely on the contract language and the general limits on restraints, not on any statutory notice or disclosure formality.

Who owns an invention by default in Alabama?

Stanford v. Roche anchors the default. The Supreme Court held that even the Bayh-Dole Act did not displace the long-standing rule that an invention belongs to its inventor, treating that premise as the baseline against which any assignment is measured C.1.

“Since 1790, the patent law has operated on the premise that rights in an invention belong to the inventor.”

Because ownership starts with the inventor, an employer's title is derivative — it exists only if and to the extent the employee assigned it. Any third-party interest must trace back to that inventor-grantor C.3.

“Thus, although others may acquire an interest in an invention, any such interest — as a general rule — must trace back to the inventor.”

The principal exception is the employee hired to invent. Under United States v. Dubilier Condenser Corp., an employee engaged to make a particular invention who succeeds during the term of service must assign the resulting patent to the employer C.2.

“One employed to make an invention, who succeeds, during his term of service, in accomplishing that task, is bound to assign to his employer any patent obtained.”

Short of that, where the employee is neither hired to invent nor bound by a written assignment but has used the employer's time, tools, and materials to reach a concrete result, the employer's remedy under Dubilier is only an equitable shop right — a non-exclusive license to use the invention, not ownership of it. One caveat on the Alabama picture deserves emphasis: because our review found no Alabama appellate decision applying either doctrine, the answer here is a prediction of how an Alabama court would rule from the shared federal baseline, not the holding of an Alabama case. That is one more reason the dependable path for an Alabama employer is a written present-assignment (hereby assigns) clause that transfers legal title automatically on conception, rather than a future promise to assign that leaves the employer with a mere equitable claim.

Are trailing-assignment (holdover) clauses enforceable in Alabama?

Two gaps define the Alabama picture. First, there is no statute on invention assignments: nothing caps the duration of a post-employment trailing assignment or otherwise limits what such a clause may reach. Second, our review found no Alabama decision applying the state's restraint-of-trade limits to an invention-holdover clause, so the invention-specific application of those limits is genuinely open rather than settled.

The statutory backdrop is the Restrictive Covenant Act, effective January 1, 2016, which opens with a broad prohibition D.1.

“Every contract by which anyone is restrained from exercising a lawful profession, trade, or business of any kind otherwise than is provided by this section is to that extent void.”

Subsection (b) of § 8-1-190 then allows six enumerated contract types formed to preserve a protectable interest — non-hire agreements, exclusive-dealing arrangements, sale-of-business covenants, employee non-competes (two years or less presumed reasonable), customer non-solicits (18 months presumed reasonable), and dissolution agreements. A trailing invention assignment is not among them. So the threshold question — undecided in Alabama — is whether such a clause restrains the exercise of a lawful profession within the meaning of subsection (a) at all. If it is not, the Act simply does not speak to it; if it is, it does not fit neatly into the exception list, and the Act's duration presumptions, which attach to the enumerated covenant types, have not been extended to invention holdovers by any authority found in our review. The stakes of that classification are written into the Act itself: an overbroad restraint within the exceptions may be reformed, while a restraint outside the exceptions may be voided entirely D.3.

“If a contractually specified restraint is overly broad or unreasonable in its duration, a court may void the restraint in part and reform it to preserve the protectable interest or interests. If a contractually specified restraint does not fall within the limited exceptions set out in subsection (b) of Section 8-1-190, a court may void the restraint in its entirety.”

The common-law framework a court would bring to that analysis comes from DeVoe v. Cheatham: Alabama courts will not enforce a negative covenant arising out of employment unless the employer has a protectable interest, the restriction is reasonably related to that interest, the restriction is reasonable in time and place, and the restriction imposes no undue hardship D.2.

“In order to have a protectable interest, the employer must possess ‘a substantial right in its business sufficiently unique to warrant the type of protection contemplated by [a] noncompetition agreement.’”

A currency note on DeVoe: it construed former Ala. Code § 8-1-1, which the Restrictive Covenant Act repealed and replaced for agreements signed on or after January 1, 2016. The protectable-interest concept at the heart of DeVoe carries forward — the Act itself conditions its exceptions on preserving a protectable interest — so DeVoe remains the canonical Alabama articulation of the framework, but no decision found in our review has re-run that framework, under either the old statute or the Act, for a trailing invention-assignment clause.

Extending these principles to holdover assignments is therefore a prediction, not a holding. An Alabama court asked to enforce a clause sweeping in inventions an ex-employee conceives after leaving would most likely ask whether the clause protects a genuine protectable interest — trade secrets or confidential information the ex-employee carries out the door — and whether its reach is reasonable, rather than applying any invention-specific rule. Out-of-state authority that has voided open-ended post-employment invention assignments applies other states' law and is at most analogous; it is not Alabama law and should not be treated as controlling here. The safe reading is that an overbroad trailer clause is at meaningful risk in Alabama — either as a void restraint outside the Act's exceptions or as an unreasonable one within them — but the precise standard for invention holdovers has not been decided.
