Invention Assignment Agreement
Texas
Can an Invention Assignment Agreement require employees to assign ownership of inventions created outside of work hours?
I recently signed an employment contract that includes an Invention Assignment Agreement, which states that I must assign ownership of any inventions I create during or outside of work hours. While I understand the need for the agreement in relation to work-related inventions, I am concerned about its implications for inventions I create on my own time and using my own resources. Can an employer legally require me to assign ownership of inventions created outside of work hours?
Randy M.
Invention Assignment Agreements usually require employees to hand over rights to any inventions they come up with during their employment. But things can get tricky when the agreement tries to claim ownership of something you created on your own time using your own resources. What’s Generally Enforceable Employers often write these agreements in broad terms, sometimes trying to cover anything you invent while you're employed, even if it’s unrelated to your job. Courts usually uphold fair agreements, but they’ll look closely at anything that seems to overreach. Most states try to strike a balance. If an invention is directly tied to your work or the company’s business, the employer may have a valid claim. But if it’s something truly independent that you built on your own time without company tools or knowledge, you’re more likely to keep it. State Laws That Protect Employees Some states have gone further and passed laws that give employees more protection. California’s Labor Code § 2870 is probably the most well-known. It says employers can’t force you to assign inventions that were developed entirely on your own time without using any company resources. The exception is if the invention is connected to the company’s business, research, or your actual job duties. Other states like Washington, Illinois, Delaware, Minnesota, and North Carolina have similar laws. New York passed its own version in 2023, called Labor Law § 203-f, which follows California’s lead. Most of these laws also require employers to give written notice to employees about their rights. In states without specific laws, courts typically rely on general contract principles and public policy. If a contract tries to claim every idea you’ll ever have, that language probably won’t hold up. But if the invention overlaps with your employer’s field, even if you built it at home, the company could still have a real claim. When Employers Still Have Rights Even with legal protections, there are a few situations where the company can still argue ownership: 1. If the invention is related to the business or current projects. 2. If you used any company tools, software, workspace, or confidential info. 3. If the invention came out of your assigned job duties, even if you worked on it after hours. These carve-outs are broader than most people realize. For example, if you’re a software engineer and your side project uses the same coding language or solves a similar problem as your employer’s product, that could raise red flags, even if you used your own laptop at home. How to Protect Your Own Inventions If you want to make sure you keep the rights to something you’ve created, documentation is key. Keep records of when you worked on it, what tools you used, and how it relates (or doesn’t relate) to your job. Don’t use your work email, computer, or cloud storage. And read your agreement carefully. Some contracts require you to disclose all inventions, even personal ones. Disclosure doesn’t always mean you have to assign it, but it can start a conversation you’d rather avoid. The Shop Right Rule Even if you own your invention, your employer might still be able to use it under what’s called the “shop right” doctrine. This means that if you used company time, tools, or resources, the company may have a free, nonexclusive license to use your invention in its operations. You’d still own it, but you couldn’t stop them from using it. Why Jurisdiction Matters The state where you work usually controls which laws apply to your agreement, not the state where your company is based. That can make a big difference. For example, engineers in California have strong statutory protections. Employees in Texas may need to rely on general contract law instead. The Final Analysis Your best move is to have an employment attorney review your agreement. The details matter, and so does your state's law. A good attorney can explain what's enforceable, help you negotiate better terms (like explicit carve-outs for personal projects), and show you how to protect your own work without violating your contract. If you're looking for this type of guidance, the attorneys on Contracts Counsel are available to help. Whether you need a quick contract review or full representation, you can connect with experienced employment lawyers who understand the nuances of invention assignment agreements in your state.

Technology Transfer Agreement
Arizona
What are the key provisions and considerations to include in a Technology Transfer Agreement?
I am a software developer who has recently developed a proprietary technology and I am considering entering into a Technology Transfer Agreement with a company interested in licensing and commercializing my technology. I want to ensure that the agreement protects my intellectual property rights and outlines the terms and conditions for the transfer of technology, but I am unsure about the key provisions and considerations that should be included in such an agreement.
Randy M.
When you're dealing with a technology transfer agreement, it's important to understand that you're not selling your software. You're licensing it. That might seem like a small difference, but it really isn't. Licensing means you're keeping ownership of your intellectual property while letting someone else use it under clearly defined terms. If you're based in Arizona, you've got a legal system that takes written contracts seriously and generally holds both parties to exactly what’s spelled out. So clarity matters—a lot. Be Specific About What's Being Licensed Don't just say you're licensing "software." Spell out what that includes. Are you talking about the source code? Object code? Documentation? APIs? Maybe there's configuration data, algorithms, or some embedded proprietary know-how. Lay it all out. Also, be clear on whether things like updates, bug fixes, or patches are part of the deal or if those require separate terms. Courts in Arizona won't guess what you meant. They’ll go by what’s in the document. Keep Your IP Rights Locked Down Make sure the agreement says you're not transferring ownership. You're only granting the rights specifically listed in the license. Anything not spelled out stays with you. Without that language, you could run into disputes later—especially if the licensee makes improvements. Want to avoid headaches? Clearly state that you own any enhancements unless you decide otherwise. Be Intentional About the License Structure Think through how you’re structuring the license. Is it exclusive, non-exclusive, or somewhere in between? An exclusive license can be powerful, but it limits your flexibility. If you're giving up other opportunities, it's reasonable to ask for higher compensation and make sure the licensee meets clear performance targets. On the flip side, a non-exclusive license gives you room to work with others. You can also narrow the license by geography, industry, or even specific use cases. And don’t forget to address sublicensing. If it’s allowed, include approval rights and make sure you’re compensated fairly if they sublicense to others. Choose a Payment Model That Reflects Value There’s no one-size-fits-all way to get paid. You might go with an upfront fee for past development work, ongoing royalties based on sales, or milestone payments tied to things like product launches or regulatory approval. Each has its pros and cons. Whatever you choose, protect yourself with audit rights. You want access to the licensee’s records if something seems off. That usually means giving them notice, checking things during business hours, and shifting the audit costs if the discrepancies are significant. Protect Your Work from Unintended Use If you’ve used open-source components, you need to disclose that—and understand how those licenses impact what you can legally offer. GPL code, for example, can bring in obligations that might not work with your business model. Copyright registration isn’t mandatory, but it gives you the ability to sue in federal court and can unlock statutory damages and legal fees. If you've developed novel algorithms, you might consider a patent—but only if the innovation meets the standards. It's not always worth the cost, so weigh that carefully. Make Sure the Licensee Does Something with Your Tech If you’re giving someone exclusive rights, set performance expectations. What does commercialization look like to you? It might mean releasing a product by a certain date, hitting minimum sales, or committing to a marketing budget. If those things don’t happen, you need a remedy—like converting the license to non-exclusive or ending the agreement altogether. The goal is to make sure your technology doesn’t sit unused. Clarify Support and Ongoing Involvement Are you expected to provide support? If so, spell out exactly what that means. Documentation, training, installation help, bug fixes, future updates—whatever it is, define it. Also decide whether that’s included in the license or billed separately. If you’re providing source code, put strict confidentiality and usage terms in place. In some cases, a source code escrow might be appropriate, with release conditions like your bankruptcy or failure to maintain the code. Limit Your Liability Arizona has adopted the Uniform Commercial Code, so if you don’t include specific disclaimers, you might be stuck with certain implied warranties. That includes things like fitness for a particular purpose. You’ll want to limit that while still affirming that you own the software and that it generally works as described. Also, set a cap on liability. Most developers limit it to the total fees paid under the agreement and exclude indirect or punitive damages. You don’t want to be held responsible for how someone else uses your tech. Mutual Indemnification Matters If someone accuses your software of infringing their intellectual property, you might agree to cover the licensee’s costs. But it needs to go both ways. They should indemnify you too—especially if they modify your code or use it in a regulated environment where compliance issues could come up. You don’t want to be liable for something outside your control. Don’t Skip Export Control Compliance Yes, export control rules apply even to downloadable software. If your product includes encryption or certain types of AI or analytics, it may fall under specific federal regulations. Many tools qualify for License Exception ENC, but that’s not automatic. Misclassification can lead to serious fines. If you're licensing internationally—or even just to a foreign-owned company based in the U.S.—you need to get this right before moving forward. Understand How Arizona Law Will Handle Your Agreement Arizona courts usually enforce what’s written. If it’s not in the contract, don’t expect the court to fill in the gaps. That makes detailed drafting essential. Arizona also supports reasonable non-competes and confidentiality terms, which isn’t true in every state. Just make sure any restrictions are tied to legitimate business interests and kept within reasonable limits for time and geography. Spell Out What Happens at the End Termination clauses are your safety net. Cover scenarios like breach, bankruptcy, missed milestones, or even changes in company control. Include cure periods where appropriate. Be specific about what happens when the agreement ends—does the licensee have to stop using the software immediately? Can they finish selling what’s already been produced? Make that clear. Also, specify which obligations survive termination. Usually, confidentiality and IP rights continue, even after the main agreement ends. Plan Ahead for Disputes Choose Arizona law to govern the agreement. If your licensee is in another state or country, decide where and how disputes will be handled. Arbitration can be quicker and cheaper, but it might limit your access to things like injunctive relief. Consider requiring mediation first to give both sides a shot at resolving issues early. And don’t forget a prevailing party clause—Arizona courts do enforce them, and it could help you recover attorneys’ fees if you end up in a legal fight. The Final Analysis Technology licensing isn't just about protecting your IP. It's about setting clear, enforceable expectations from the start. Arizona law gives you the tools to do that, but it only works if your agreement is well-drafted and forward looking. Define what you're licensing, retain ownership, protect your downside, and make sure the deal drives results, not just risk. If you're a software developer navigating a tech transfer deal or reviewing an agreement someone else drafted, don’t go it alone. Having the right legal language in place from day one can prevent years of headaches down the road.

Developer Agreement
Washington
Can a developer agreement restrict me from sharing my own code with others?
Can a developer agreement legally restrict me from sharing my own code with other developers or open-source communities? I am a software developer who has recently been offered a contract to work on a project for a company, and they have presented me with a developer agreement that includes a clause stating that I cannot disclose or share any of the code I develop during the project. However, I am passionate about collaborating with other developers and contributing to open-source projects, so I am concerned about the implications of this restriction on my ability to share my code and participate in the development community. I want to understand the legal implications and potential consequences of signing such an agreement.
Randy M.
You might think that because you wrote the code, you have the right to share it, but that’s not how developer agreements usually work. In Washington State, these contracts are enforceable, and they can absolutely stop you from sharing or reusing code you created during a project. It really comes down to ownership, and under most contracts, that ownership belongs to the company, not you. Let’s Talk About Who Owns the Code When you sign a developer agreement, you’re usually agreeing to one of two things: either it’s a “work-for-hire” deal or you're assigning your intellectual property rights. Either way, the result is the same. The company owns whatever you build for them. Since they own it, they get to decide what happens to it. Even if you’re the one who wrote every line, that doesn’t mean you have the right to reuse or share it if you’ve already signed those rights away. This kind of setup is standard in the tech world. Companies need to protect their IP, especially when it includes competitive advantages or trade secrets. That’s why they ask developers to assign rights and agree to keep things confidential. What About Washington State Law? Washington does offer some protection to developers, but it’s limited. There’s a statute, RCW 49.44.140, that says employers can’t claim ownership of inventions you created entirely on your own time, using your own resources, and completely unrelated to their business. That sounds helpful, but here’s the catch. It only applies if you’re an employee, not an independent contractor. And even then, the second your work overlaps with their business or involves any company resources, the protection probably doesn’t apply. So if the code you’re writing is part of a contract, or even just loosely connected to the company’s business, then the company likely owns it. Why This Matters If you violate the agreement, you’re not just risking a slap on the wrist. The company could send a takedown notice to GitHub, file for an injunction, or even sue for breach of contract or copyright infringement. If the code includes anything proprietary, like business logic or algorithms, they might also go after you for trade secret misappropriation. And beyond the legal problems, there’s your reputation to think about. Word travels fast in development circles, especially in local communities. Getting labeled as someone who mishandles IP can make future contracts harder to land. How to Protect Yourself The good news is that you still have leverage before you sign. A lot of companies start with broad IP assignment language, but they’re often open to carving out exceptions. You can ask to include a “prior inventions” schedule that lists tools, frameworks, or libraries you already created. That way, you can keep using your own work in other projects. If open-source contribution is important to you, say so upfront. Some companies will allow developers to contribute non-proprietary or generic components to open-source projects, especially if those contributions don’t compete with their business. Just make sure it’s all clearly spelled out in writing and approved in advance. You might also negotiate a time limit on confidentiality terms. The company will likely want to own the core project code permanently. That doesn’t mean you can’t eventually talk about general techniques or patterns you used, especially after some time has passed. Smart Moves Before You Sign Before you agree to anything, take a moment to list any existing code or tools you plan to use. Try to get those explicitly excluded from the IP assignment, or at least confirm that you’ll retain the right to use them elsewhere. And again, if open-source is part of your career plan, be upfront. Get language in the contract that allows you to publish select components with written approval. If you develop a useful utility during the project and think it might have broader uses, talk to the company before the contract ends. See if they’d be open to letting you open-source it or license it back to yourself for use in future projects. When It’s Time to Bring in a Lawyer If all this feels high-stakes, and it often is, consider having a tech-savvy attorney take a look. A good lawyer can help spot overly aggressive clauses, suggest better language, and help you protect both your rights and your long-term goals. This is especially important if you’re actively contributing to open-source or if you’ve built up your own libraries over time. A little legal help now can save you a lot of trouble later.

Trademark Search
Florida
Is a trademark search necessary before registering my business name?
I am in the process of starting my own business and have chosen a unique name for it, but I am unsure if it is necessary to conduct a trademark search before officially registering the name. I want to ensure that my chosen business name does not infringe upon any existing trademarks and that I can safely use and protect it in the future.
Randy M.
Running a trademark search before registering your business name isn’t legally required, but it’s one of the most important steps you can take to avoid future problems. Registering your name with the state forms your business entity, but it doesn’t give you trademark rights. Trademark rights come from use in commerce and, if you file with the USPTO, registration at the federal level. Why a Trademark Search Matters The central legal test in trademark law is whether a name is likely to cause consumer confusion. That means you don’t need to copy someone else’s name exactly to get into trouble. Even something that looks or sounds similar in the same or related industry could be enough. If you skip the search and move forward, you risk: • Infringement claims: Another company could demand you stop using the name and, if necessary, sue for damages. • Forced rebranding: If you’ve already invested in your logo, website, signage, or marketing materials, being forced to change your name can be expensive and disruptive. • USPTO rejection: If you apply for a federal trademark, the USPTO will run its own search. If they find a confusingly similar mark, your application will be denied and you’ll lose the filing fees. A well-documented example is when small businesses open under a catchy name, only to receive a cease-and-desist letter from a national chain using a similar name in the same space. Even if you’re in a different state, a federal registration gives that company priority rights nationwide. A proper trademark clearance search should cover more than just identical names. You’ll want to check: • Federal database (USPTO TESS): This is the official record of all registered and pending federal trademarks. • State trademark databases: Many businesses register marks only at the state level. • Common law sources: Unregistered marks can still have legal protection. Check Google, industry directories, social media, and domain names. • Similar variations: Look for phonetic equivalents and alternative spellings, such as “Kwik” for “Quick,” or slight wording changes that could still cause confusion. Professional Assistance You can run an initial search yourself at no cost, but these searches have limits. For example, the USPTO database won’t flag marks that are spelled differently but sound alike, or names with similar meanings. Attorneys and specialized search firms use tools that uncover those kinds of risks. While hiring a professional costs more upfront, it’s often far cheaper than litigation or a rebrand. Limitations A search doesn’t guarantee that your name will never be challenged. Trademark law involves judgment calls about how similar marks are and whether they overlap in goods or services. Still, a thorough search puts you in a much stronger position to defend your choice and move toward federal registration if you want nationwide rights.

Trademark Cease And Desist
California
Can I ignore a cease and desist letter for trademark infringement if I believe my use of the mark is fair use?
I recently received a cease and desist letter from a company claiming that my use of their trademark in my blog posts constitutes trademark infringement. However, I am using the mark in a descriptive manner to criticize and comment on their products, which I believe falls under fair use. I am unsure of how to proceed and whether I can ignore the cease and desist letter without facing legal consequences.
Dolan W.
Hello! Thank you for posting this question. In your case, the other party may claim that you are infringing on their trademark, but proving it is a different case. The Lanham Act provides for a cause of action for infringement of both registered and unregistered trademarks. (15 USC Section 1114(1)(a); 15 USC Section 1125(a)(1)A).) The 9th Circuit Court of Appeals has laid out some elements to help determine whether it creates an infringement lawsuit. 1. The complaining party has to prove they have a valid, protectable trademark and that they own that trademark; 2. The complaining party must prove that a mark is similar, and it was used without the consent of the moving party in a manner that is likely to cause confusion among ordinary consumers as to the source, sponsorship, affiliation, or approval of the goods. The likelihood of confusion can occur at the time of the sale, when there is initial interest by a consumer, or even after the sale, if the confusion causes a consumer to no longer buy a service or product connected to the mark. The court considers things like the strength of the original mark, whether you are using it for some fair use purpose, the similarity, the proximity of the products and marketing channels, whether there’s actual confusion, the defendant’s intent, the quality of respective products, and the sophistication of the customers. (Polaroid Corp. v. Polard Elecs. Corp. 287, F.2d. 492, 495 (2d Cir. 1961.) So what this means is that it'd have to be litigated, but you can argue you are not trying to sell products or services using their mark, but rather you are using it for some other purpose, such as to educate people about their business practices. Best of luck!
