Can a Massachusetts employer require assignment of every invention?
No — but for a different reason than in California. Massachusetts has no employee-invention-assignment statute, so there is no statutory list of inventions a clause cannot reach. Scope is instead set by contract against the backdrop of common law: the inventor owns a patentable invention by default, and an employer takes title only through a valid assignment. When the Legislature wrote the Massachusetts Noncompetition Agreement Act, G.L. c. 149, § 24L, it confirmed that it was leaving invention-assignment to contract — its definition of a noncompetition agreement expressly excludes invention assignment agreements, regulating non-competes while leaving the scope of invention-assignment untouched. On a touch screen, a tap shows all 2 sources in this group.
Massachusetts has never enacted a §2870-style invention-assignment statute, so there is no own-time carve-out, no condition-of-employment bar, and no statutory notice rule on the books. What a Massachusetts clause may reach is a question of contract law, bounded only by the common-law limits on restraint of trade.
The clearest signal that the Legislature legislated around invention-assignment without capping its scope is § 24L itself. In defining a noncompetition agreement, the Act lists a series of agreements that are not noncompetition agreements, and invention assignment agreements sit squarely on that list — so the non-compete statute's caps and presumptions do not govern them .
Because no statute supplies the rule, the starting point is the federal patent-law baseline that governs title to a patentable invention everywhere: rights belong to the inventor. A Massachusetts employer therefore depends on a written present-assignment clause to take title at all .
So the honest answer is that an employer can draft broadly, but its reach comes from the contract, not from any statute compelling assignment — and that contract is measured against the default that the inventor owns and against the common-law ceiling on unreasonable restraints.

Section 24L's definition of a noncompetition agreement expressly does not include invention assignment agreements (along with NDAs, garden-leave clauses, and other listed categories), so the Massachusetts non-compete statute's caps and presumptions do not govern an invention-assignment clause.

Must a Massachusetts employer notify the employee?
No. Massachusetts has no invention-assignment statute, so no statutory notice or carve-out-disclosure requirement applies; a clause's validity does not depend on any notice to the employee. Nothing in Massachusetts law mirrors California's section 2872 or Washington's RCW 49.44.140(3), so the inquiry collapses into ordinary contract law and the default-ownership rules below .
That absence cuts both ways. There is no notice box an employer must check at signing — but there is also no statutory own-time carve-out doing the work a California notice would point to. What governs instead is whether the employee actually assigned the invention and, if not, whether one of the common-law overlays gives the employer rights — the questions taken up under default ownership.

Who owns an invention by default in Massachusetts?
The inventor. Massachusetts follows the federal patent-law baseline that title to a patentable invention begins with the employee who conceived it, and the Supreme Judicial Court has applied that rule for more than a century: an employee engaged for work of a noninventive nature keeps the inventions he makes during the employment unless he has assigned them. An employer reaches the invention without an express assignment only through two narrow common-law overlays — the hired-to-invent doctrine and the shop right — both drawn in National Development Co. v. Gray. On a touch screen, a tap shows all 2 sources in this group.
The SJC stated the default plainly in National Development Co. v. Gray. Merely taking a job that calls for noninventive services does not cost the employee the inventions he makes along the way — even improvements on the employer's own devices .
An earlier SJC decision had already fixed the same starting point. In American Circular Loom Co. v. Wilson, the court held that the invention and its patent belong to the inventor unless he has assigned his right or made an enforceable agreement to do so — and that this is true even where his job was to improve the employer's machinery .
Because ownership starts with the inventor, an employer's title is derivative: it exists only if and to the extent the employee granted it. Any third-party interest must trace back to that inventor-grantor .
Gray supplies the first overlay. Where an employee is engaged to invent — to accomplish a particular inventive result the employer set out to obtain — the invention belongs to the employer even without an express ownership term in the contract .
The second overlay is narrower still. When an employee who was not hired to invent uses the employer's time, materials, and equipment to make an invention, the employer does not take title; it takes only a shop right — a license, not ownership .
Both overlays are fact-bound, and neither is a substitute for a written clause. A Massachusetts employer that wants clean title relies on a written present-assignment (hereby assigns) clause — present-tense language that transfers legal title automatically on conception, rather than a future promise to assign.

National Development Co. v. Gray states the Massachusetts default rule: an employee engaged for services of a noninventive nature does not lose rights to inventions he makes during the employment, even improvements on the employer's own devices, absent an assignment.
One by merely entering an employment requiring the performance of services of a noninventive nature does not lose his rights to any inventions that he may make during the employment
See National Development Co. v. Gray, 316 Mass. 240 (1944).
American Circular Loom Co. v. Wilson holds that an invention and its patent belong to the inventor unless he has assigned his right or made a valid and enforceable agreement to assign — even where the employee's duty was to improve the employer's machinery.
The invention and the patent thereon belong to the inventor, to whom the patent has been issued, unless he has made either an assignment of his right or a valid and enforceable agreement for such an assignment
See American Circular Loom Co. v. Wilson, 198 Mass. 182 (1908).
Stanford v. Roche holds that although others may acquire an interest in an invention, that interest as a general rule must trace back to the inventor — so an employer takes title only through an assignment from the employee-inventor.
Thus, although others may acquire an interest in an invention, any such interest — as a general rule — must trace back to the inventor.

National Development Co. v. Gray recognizes the hired-to-invent overlay: where an employee is engaged to invent, the resulting invention belongs to the employer even with no express ownership provision in the employment terms.
the invention belongs to the employer even though the terms of employment contain no express provision dealing with the ownership of whatever inventions may be developed.
See National Development Co. v. Gray, 316 Mass. 240 (1944).
National Development Co. v. Gray recognizes the shop right: where an employee not hired to invent uses the employer's equipment, materials, and labor to make an invention, the employer does not take title but holds a nonexclusive irrevocable license to use the invention.
the employer has a shop right in the invention which gives him a nonexclusive irrevocable license to use the invention.

Are trailing-assignment (holdover) clauses enforceable in Massachusetts?
Only so far as they are reasonable. No Massachusetts statute caps an invention-assignment holdover specifically, and § 24L removes invention assignment agreements from the non-compete act's reach, so its presumptions do not supply the ceiling either. A post-employment trailing-assignment clause that operates as a restraint on the employee's future work is therefore tested under Massachusetts common-law reasonableness for restrictive covenants: a restraint is enforced only if it is reasonable on all the circumstances. No Massachusetts appellate decision found in our review squarely fixes the reasonable bound for an invention-assignment holdover specifically, so the limit is the general reasonableness standard rather than a bright line. On a touch screen, a tap shows all 2 sources in this group.
Start with what is missing. Massachusetts has never enacted a §2870-style statute, and the one statute that polices post-employment restraints — the Noncompetition Agreement Act — defines a noncompetition agreement to exclude invention assignment agreements. The Act's durational presumptions and notice rules therefore do not reach an invention-assignment holdover; the clause is left to common-law restraint principles .
“(vii) invention assignment agreements; (viii) garden leave clauses”
Those principles supply the test. Massachusetts enforces a contractual restraint on a person's future work only to the extent it is reasonable. In All Stainless, Inc. v. Colby, the SJC stated the governing standard for a post-employment restrictive covenant: it is enforced if reasonable on all the circumstances .
That is a standard, not a tailored rule. No Massachusetts appellate decision found in our review squarely decides how far a post-employment invention-assignment holdover may reach before it becomes an unreasonable restraint — All Stainless itself addressed a covenant not to compete, not an invention-assignment trailing clause. A drafter should therefore treat an aggressive Massachusetts holdover clause as a reasonableness risk — keeping its duration and subject-matter scope tight — rather than rely on a settled safe harbor.

All Stainless, Inc. v. Colby states the Massachusetts common-law standard for a post-employment restrictive covenant: a covenant restraining a person's future work is enforced only if it is reasonable on all the circumstances — the test under which an overbroad invention-assignment holdover operating as a restraint would be measured.
A covenant not to compete contained in a contract for personal services will be enforced if it is reasonable, based on all the circumstances.

Do not paper a Massachusetts employee with an out-of-state assign-everything invention-assignment form. The inventor owns by default here, so present-tense present-assignment language — not a bare promise to assign — is what actually moves title. There is no Massachusetts notice or carve-out-disclosure requirement, so a clause copied from a section 2872 or RCW 49.44.140(3) state carries machinery Massachusetts does not require; conversely, an aggressive post-employment holdover clause that such a form often includes risks being void as an unreasonable restraint, because § 24L leaves invention-assignment holdovers to common-law reasonableness rather than a statutory ceiling. Limit the assignment to inventions tied to the employment, and keep any trailing clause narrow. On a touch screen, a tap shows all 2 sources in this group.
What does federal law require a confidentiality and invention assignment agreement in Massachusetts to say about whistleblowers and pay?
An employee confidentiality, non-compete, or invention assignment agreement signed or updated now that governs trade secrets or other confidential information must give the Defend Trade Secrets Act whistleblower-immunity notice, and for employees the National Labor Relations Act covers, Section 7 of that Act protects concerted activity, including joining together over pay and working conditions, that a broad confidentiality clause can restrict. The employer may satisfy the notice duty by cross-referencing a qualifying policy document provided to the employee, but an employer that omits the notice may not be awarded exemplary damages or attorney fees under the Defend Trade Secrets Act in an action against an employee who was not given notice.
The notice describes a federal immunity: an individual cannot be held liable under federal or state trade-secret law for disclosing a trade secret in confidence to a government official or an attorney solely to report or investigate a suspected violation of law, or in a court filing made under seal. For an agreement signed or updated now, the duty to give that notice reaches any agreement with an employee that governs trade secrets or other confidential information, whatever else the agreement does.
Section 7 gives employees the National Labor Relations Act covers a statutory right to engage in concerted activity for mutual aid or protection, including joining together to improve pay and working conditions. For employees the Act covers, the Board's work-rule standard adopted in 2023 makes a rule presumptively unlawful if it has a reasonable tendency to chill employees from exercising their Section 7 rights; an employer can rebut that presumption only by showing a legitimate and substantial business interest it cannot serve with a more narrowly tailored rule. The 2023 standard may change, but the Section 7 right it enforces is statutory. State law may add its own requirements for the same clauses.
A form carried over without the immunity notice, or a cross-reference to a reporting policy the employee never received, leaves the confidentiality clause without a valid notice, so the Act's exemplary damages and attorney fees are unavailable against that employee. A Confidential Information definition that sweeps in pay and working conditions with no carve-out exposes the employer to an unfair-labor-practice finding for employees the Act covers.

Under the work-rule standard the Board adopted in 2023, a rule with a reasonable tendency to chill employees from exercising their Section 7 rights is presumptively unlawful unless the employer proves a legitimate and substantial business interest it cannot advance with a more narrowly tailored rule.
Under the new standard adopted in Stericycle, the General Counsel must prove that a challenged rule has a reasonable tendency to chill employees from exercising their rights. If the General Counsel does so, then the rule is presumptively unlawful. However, the employer may rebut the presumption by proving that the rule advances a legitimate and substantial business interest and that the employer is unable to advance that interest with a more narrowly tailored rule.
