Employee Invention Assignment in New Jersey

Can a New Jersey employer require assignment of every invention?

Subsection a.(1) frames the carve-out as a limit on what an assignment promise can do. However broadly the contract is written, it does not reach an invention the employee made on their own time and with their own resources unless one of two statutory exceptions applies A.1.

“Any provision in an employment contract between an employee and employer, which provides that the employee shall assign or offer to assign any of the employee's rights to an invention to that employer, shall not apply to an invention that the employee develops entirely on the employee's own time, and without using the employer's equipment, supplies, facilities or information, including any trade secret information, except for those inventions that:”

The two exceptions are joined disjunctively. An own-time invention falls back within the employer's reach if it either relates to the employer's business or anticipated research or development, or results from the employee's work A.1.

“(a) relate to the employer's business or actual or demonstrably anticipated research or development; or (b) result from any work performed by the employee on behalf of the employer.”

Subsection a.(2) supplies the teeth. A provision that tries to require assignment of an invention the statute excludes is not merely unenforceable as written but declared against the public policy of the state A.2.

“To the extent any provision in an employment contract applies, or intends to apply, to an employee invention subject to this subsection, the provision shall be deemed against the public policy of this State and shall be unenforceable.”

Section 34:1B-265 closely tracks California Labor Code § 2870 and New York Labor Law § 203-f — the own-time, own-resource carve-out and the same two business-or-work exceptions. New Jersey's operative remedy is to render the offending provision unenforceable to the extent it overreaches, and the statute speaks only of unenforceability rather than of any judicial blue-pencil or reformation. A New Jersey drafter should not assume a court will rewrite an overbroad provision into a compliant one rather than simply declining to enforce it, so the assignment language should be confined to what the statute allows on its face.

Must a New Jersey employer notify the employee?

The statute is short and self-contained. Subsection a. defines which inventions an assignment clause cannot reach and declares an overreaching provision unenforceable, and subsection b. bars an employer from requiring a void provision as a condition of employment or continued employment. Nowhere does § 34:1B-265 condition the carve-out, or the validity of a permissible assignment clause, on the employer giving the employee any notice B.1.

“No employer shall require a provision made void and unenforceable by this act as a condition of employment or continued employment.”

The contrast with the two notice states is worth flagging, because a multistate employer that built its form around the California § 2872 or Washington RCW 49.44.140(3) notice may carry that language into New Jersey and assume it is required here. It is not. The absence of a notice requirement cuts the other way too: a New Jersey employer cannot cure an overbroad assignment clause by giving notice of the carve-out, because § 34:1B-265 makes the offending provision unenforceable regardless of what the employee was told. The statute's silence on notice means the work is done entirely by the scope of the assignment language itself.

Who owns an invention by default in New Jersey?

Stanford v. Roche anchors the default. The Court held that 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 must be 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 in the invention 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.”

New Jersey's own law follows the same path. In Kinkade, the Supreme Court confirmed that an invention conceived during employment does not, by that fact alone, pass to the employer C.2.

“the mere fact that an invention was conceived and developed while the inventor was employed by another does not give to the employer any right in or title to the invention.”

The narrow exception is the hired-to-invent situation, drawn from the same federal common law New Jersey applies. Where the employee was engaged specifically to make the invention and succeeds during the term of service, the resulting patent is owed to the employer C.4.

“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.”

Where the employee is not hired to invent, the employer is not necessarily empty-handed. Kinkade recognizes the equitable shop right: when the employee developed the invention during working hours with the aid of fellow employees and the use of the employer's machinery and materials, the employer obtains an irrevocable but non-exclusive right to the invention C.5.

“in the second instance, and this is the ‘shop right rule,’ the employer has an irrevocable but non-exclusive right to the invention.”

But a shop right is only a non-exclusive right to use, not ownership, and the hired-to-invent doctrine is fact-intensive and narrow. Neither is a substitute for a written clause. The dependable path for a New Jersey employer is a written present-assignment (hereby assigns) clause — present-tense language that transfers legal title automatically on conception, rather than a future promise to assign — operating within the boundaries § 34:1B-265 imposes.

Are trailing-assignment (holdover) clauses enforceable in New Jersey?

Start with the governing standard. Ciavatta holds that a holdover clause is enforceable only when reasonable, and that reasonableness is measured by the three-prong test New Jersey applies to noncompetition covenants D.1.

“we conclude that holdover agreements are enforceable when reasonable, and that in determining if the post-termination restriction is reasonable, we will apply the three-prong test of Solari/Whitmyer.”

The three prongs come from New Jersey's restrictive-covenant law. A restraint is reasonable only if it protects the employer's legitimate interests, imposes no undue hardship on the employee, and is not injurious to the public D.2.

“simply protects the legitimate interests of the employer, imposes no undue hardship on the employee and is not injurious to the public.”

Because a holdover clause reaches an employee's post-employment work, Ciavatta also directs courts to read such provisions narrowly. A contractual provision requiring assignment of post-employment inventions is strictly construed and must be fair, reasonable, and just D.3.

“courts strictly construe contractual provisions that require assignment of post-employment inventions; they must be fair, reasonable, and just.”

So the New Jersey limit on holdover clauses is reasonableness, applied through a settled three-prong test rather than a statutory ceiling as in California or an open void as in a state with no statute at all. A trailer clause narrowly tied to inventions conceived during employment, or to a short and defined trailing period for inventions derived from the employer's confidential information, stands on far firmer ground than an aggressive provision that sweeps in an ex-employee's independent post-employment inventions and thereby functions as a disguised noncompete. Ciavatta itself refused to enforce the holdover clause on its facts, an outcome that underscores how far short of an assign-everything tail the reasonable line falls.
