Can a Texas employer require assignment of every invention?
There is no Texas statute on the subject either way. Unlike California (Labor Code section 2870) or Washington (RCW 49.44.140), Texas has no employee-invention-assignment statute and therefore no protected category of own-time inventions that a clause is forbidden to reach. Scope is set entirely by the assignment contract, against a federal-law backdrop in which the inventor owns the invention unless and until it is assigned — so what the employer can require is a matter of contract drafting and the ordinary limits on restraints of trade, not a statutory carve-out.
Watch for a false friend in the Texas code. The one Texas statute with invention in its title — Chapter 52 of the Business and Commerce Code, captioned Invention Development Services — does not limit employee-assignment clauses at all. It is consumer-protection law regulating invention-promotion businesses that solicit inventors, and it has nothing to say about who owns an employee's invention or how broadly an employer may draft an assignment. There is no Texas analogue to section 2870; the only outer bound on an assignment clause's reach is the common law of contracts and, for any post-employment reach, the restraint-of-trade reasonableness rules in Business and Commerce Code chapter 15.
Because no statute supplies a default, the federal patent-law baseline controls. Stanford v. Roche restates the premise that, absent an effective assignment, rights in an invention belong to the inventor .
That baseline is what makes the contract language do all the work. Because ownership begins with the inventor, an employer acquires rights only by assignment; any interest the employer claims must trace back to the inventor-grantor .

A.1 Bd. of Trustees of the Leland Stanford Junior Univ. v. Roche Molecular SystemsStanford v. Roche confirms the long-standing premise of U.S. patent law that rights in an invention belong to the inventor — the federal default that governs in a state, like Texas, with no invention-assignment statute.
Since 1790, the patent law has operated on the premise that rights in an invention belong to the inventor.

A.2 Bd. of Trustees of the Leland Stanford Junior Univ. v. Roche Molecular SystemsStanford 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 a Texas 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.

Must a Texas employer notify the employee?
No. Texas 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. There is no own-time carve-out to disclose and nothing for the employer to warn the employee about — the only question is whether the assignment language is effective to transfer the inventor's default title .
This is the structural contrast with the notice states. California requires a written notice under Labor Code section 2872 and Washington under RCW 49.44.140(3), each tied to a statutory own-time carve-out. Texas has neither the carve-out nor the notice. A multistate employer that built its form around the California or Washington notice may carry that language into Texas, but here it is surplusage rather than a validity requirement: a compliant Texas assignment clause works whether or not the employee was given any notice, because the work is done entirely by the scope and tense of the assignment language itself .

B.1 Bd. of Trustees of the Leland Stanford Junior Univ. v. Roche Molecular SystemsStanford v. Roche confirms that rights in an invention belong to the inventor absent an effective assignment — so in Texas, with no notice statute, a clause's validity turns on the assignment language transferring the inventor's default title, not on any notice to the employee.

Who owns an invention by default in Texas?
The inventor. Absent a written assignment, the baseline rule under federal patent law — which governs who holds title to a patentable invention in Texas as elsewhere — is that rights belong to the employee who conceived it. The U.S. Supreme Court restated that premise in Stanford v. Roche, and although others may acquire an interest, that interest must trace back to the inventor. Texas recognizes two narrow common-law overlays that can give an employer rights without an express assignment — the hired-to-invent doctrine and the shop right — but neither is a substitute for a precise present-tense assignment clause.
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 .
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 .
The first overlay is the hired-to-invent doctrine. Where an employee is engaged specifically to make an invention or to solve the particular problem the invention solves and succeeds during the term of service, the employee is bound to assign the resulting patent to the employer — equitable title follows the inventive assignment even without an express clause .
The second overlay is the shop right, which Texas courts apply as a matter of federal common law. Where an employee uses the employer's time, tools, and the services of other employees to make and reduce an invention to practice, the employer does not take ownership but does receive a license to use it. The Fifth Circuit, in a Texas dispute, framed the doctrine in just those terms .
“the employer is the recipient of an implied nonexclusive, royalty-free license”
Both overlays are narrow and fact-intensive, which is why a Texas employer relies instead on a written present-assignment clause. The tense matters in Texas as a question of federal patent law: a clause that says the employee does hereby assign transfers legal title automatically by operation of law, whereas a mere promise to assign in the future leaves the employer with only an equitable claim until a further act of assignment. In DDB Techs. v. MLB Advanced Media, the Federal Circuit held that inventions within the scope of such a present-assignment clause passed to the company automatically, with no further act required .

Are trailing-assignment (holdover) clauses enforceable in Texas?
Only to the extent they are reasonable. No Texas statute caps invention-assignment holdovers as such, but a post-employment trailing clause that forces an employee to hand over inventions made after they leave restrains future work, and a restraint on future work is analyzed as a covenant not to compete under Business and Commerce Code section 15.50: it is enforceable only to the extent its limitations on time, geographic area, and scope of activity are reasonable and impose no greater restraint than necessary to protect the employer's legitimate interest. And when a Texas restraint sweeps too broadly, the court reforms it to reasonable limits rather than voiding it. No Texas appellate decision found in our review squarely decides the precise post-employment reach a holdover invention-assignment clause may have.
Start with the governing standard. Section 15.50(a) makes a covenant not to compete enforceable only on conditions of reasonableness, and a holdover clause reaching post-employment inventions is functionally a restraint on the departing employee's ability to work .
The consequence of overbreadth in Texas is reformation, not invalidation. Where a restraint is broader than reasonable, Marsh USA Inc. v. Cook confirms that the trial court has the authority to reform the agreement and enforce it within reasonable limits rather than strike it down .
Two cautions follow for a drafter. First, the reasonableness analysis under section 15.50 is the operative ceiling on any aggressive post-employment trailing clause, so the question is not whether the clause is enforceable as written but how far a court will pare it back. Second, because no Texas appellate decision found in our review squarely decides the precise bound for an invention-assignment holdover specifically — the cases apply the section 15.50 framework to non-competes and non-solicits — a Texas employer should treat a long trailing-assignment tail as a clause that will be reformed to a reasonable scope, not enforced verbatim.

D.2 Marsh USA Inc. v. CookMarsh USA Inc. v. Cook confirms that a Texas court confronted with an unreasonable or overbroad restraint reforms the agreement and enforces it within reasonable limits rather than voiding it.

See Marsh USA Inc. v. Cook, 354 S.W.3d 764 (Tex. 2011).
Do not assume an out-of-state assign-everything form is automatically enforceable in Texas. Because Texas has no invention-assignment statute, title passes only if the clause is drafted to pass it: present-tense does hereby assign language transfers legal title automatically, while a bare promise to assign leaves the employer with only an equitable claim. And an aggressive post-employment holdover tail will not be enforced as written — under section 15.50 it must be reasonable, and a Texas court will reform an overbroad restraint to a reasonable scope rather than void it.
