Invention Assignment Laws in Alabama: Who Owns What You Create

Federal law does not directly govern invention ownership between employers and employees; instead, the federal system relies on the Defend Trade Secrets Act (18 U.S.C. § 1836 et seq.), which provides a federal cause of action for misappropriation of trade secrets, including inventions. The DTSA defines a trade secret as information that derives economic value from not being generally known and is subject to reasonable efforts to maintain secrecy. Employers can sue for DTSA violations in federal court if an employee or third party misappropriates a protected trade secret, regardless of whether a written assignment exists.

Federal patent law (35 U.S.C.) does not automatically assign employee inventions to employers; the inventor is the initial patent holder unless there is a written assignment or "hired to invent" relationship. The Shop Rights doctrine, a federal common law rule, permits employers to use (but not exclusively own) inventions created by employees using company time and resources, even without a written agreement. However, this federal baseline applies nationwide; individual states like Alabama can impose stricter protections for employees or enforce stricter assignment clauses under their own law.

Alabama has no unique statutory scheme for invention assignment comparable to California's Employee Inventions Act (Cal. Lab. Code § 2870), which limits employer claims over employee inventions. Instead, Alabama courts apply common law contract principles derived from the Restatement (Second) of Agency and enforce invention assignment agreements that meet the state's contract formation and non-compete reasonableness standards under Ala. Code § 34-27-2.

Under Alabama common law, an employer can claim ownership of an employee's invention through a written agreement if: (1) the invention is created within the scope of the employee's job duties; (2) the invention was created using company time, materials, or resources; or (3) the employee was hired or directed to invent. Without a written agreement, Alabama recognizes the Shop Rights doctrine, allowing the employer to use (but not own) inventions created with company resources.

Alabama's treatment is generally employer-friendly compared to states like California, which restricts employer claims over inventions created on personal time without company equipment. Alabama courts enforce broad invention assignment clauses if they are reasonable in scope and relate to the company's actual or anticipated business. The state's Uniform Trade Secrets Act (Ala. Code § 8-1-1 et seq.) protects employer trade secrets and proprietary information, including inventions, from misappropriation by employees or competitors.

Covered employers include all private-sector employers of any size; there is no minimum employee threshold for invention assignment enforceability. Public employers are also bound by these principles. Remedies available under Alabama law include breach of contract damages, injunctive relief to prevent use or disclosure of the invention, and recovery of attorney's fees if the contract so provides. The state's trade secrets law permits damages for misappropriation, including lost profits and unjust enrichment.

Alabama recognizes several important exceptions to invention assignment enforceability. First, inventions created entirely on personal time, using only personal equipment, and not related to the employer's business are generally the employee's property unless a very broad written assignment specifically claims them. Second, if an invention assignment clause is unreasonably broad in scope, duration, or geography, Alabama courts may refuse to enforce it entirely or enforce only the reasonable portions, applying the state's non-compete reasonableness standard.

Third, Alabama recognizes the Shop Rights doctrine: even without a written agreement, an employer gains a non-exclusive right to use an invention created by an employee using company time, materials, or resources during work hours. However, Shop Rights do not transfer ownership to the employer; the employee retains patent rights and can license the invention to competitors (though the employer's royalty-free license survives).

Fourth, if an employee was not hired or directed to invent and created the invention entirely outside the scope of their job duties, the employer has no claim absent a written assignment specifically covering that invention. Fifth, Alabama enforces public policy exceptions: an invention assignment clause cannot be used to prevent an employee from reporting illegal activity or exercising statutory rights. Sixth, union or collective bargaining agreements may override or limit invention assignments for unionized employees. Finally, if the employer fails to provide notice of an invention assignment clause at the time of hiring or contract formation, enforceability may be challenged under Alabama contract law principles requiring mutual assent and consideration.

Step 1: Document Everything. Keep detailed records of when and where you created the invention, what resources you used (personal or company-provided), your job description at the time, and any written communications from your employer regarding the invention. Photograph or scan the invention if tangible, save emails discussing it, and note the date of creation. If the invention was developed on personal time, photograph your work environment to show it was personal. Preserve the original written invention assignment agreement or any emails referencing it. Create a timeline showing your role and the company's role in development.

Step 2: Review Your Employment Contract and Invention Assignment Agreement. Obtain and carefully read your employment agreement, offer letter, employee handbook, and any standalone invention assignment agreement. Identify the specific language claiming ownership—some assignments may be limited to work-related inventions or inventions using company resources, while others may be overbroad. Check whether the agreement was signed and dated and whether you received consideration (continued employment or hire date typically satisfies this). Determine if the agreement's scope, time limit, or geographic restriction is reasonable under Alabama law. Note any conflicting language between documents.

Step 3: File with the Appropriate Agency or Initiate a Demand Letter. If you believe the invention assignment violates your rights, do not immediately sue; instead, send a cease-and-desist or demand letter through an attorney to your employer explaining why the invention is yours and requesting written acknowledgment of your ownership. Disputes over invention ownership are contract disputes, not employment law violations reportable to the Alabama Department of Labor; there is no government filing process for invention disputes. If the employer ignores the demand letter or refuses to acknowledge your ownership, prepare to litigate in Alabama state court (Circuit Court in your county). The statute of limitations for breach of contract is six years from the date the breach occurs (usually when the employer claims or exercises ownership).

Step 4: The Investigation and Discovery Process. If litigation proceeds, the discovery process will require both sides to exchange documents (emails, invention records, employment contracts) and depose witnesses. The employer will likely argue that the invention falls within your job duties or used company resources, while you will present evidence of personal time and resources. Alabama courts do not conduct investigations; discovery is managed by the litigants and their attorneys. Expect the process to take 6–18 months from filing to trial, depending on court docket. Either party can move for summary judgment if no material facts are in dispute.

Step 5: When to Consult an Attorney and What Type. Consult an employment law attorney in Alabama immediately if your employer claims ownership of an invention you believe is yours or if you are asked to sign an invention assignment agreement and have concerns. An attorney can review the specific agreement's enforceability and advise you on your rights before signing. If the dispute has already arisen, hire an attorney experienced in intellectual property or contract litigation in Alabama state court. Many attorneys offer free initial consultations. Be prepared to provide copies of all relevant documents, your employment agreement, the invention details, and the timeline of creation. An attorney can also advise whether the dispute might involve federal patent law or trade secret misappropriation, which may require specialized intellectual property counsel.
