The IP mistakes that hurt early-stage companies are almost never exotic. They are the same handful of omissions, made in the first eighteen months when nobody has time, that surface two or three years later during a financing, an acquisition, or a dispute with a former co-founder. Each one has a cheap fix if caught early and an expensive one if caught late. Our intellectual property practice sees the same list often enough that it is worth publishing with the repair for each item.

Ownership mistakes

No founder IP assignment

Code, designs, and plans created before the company was formed belong to the individuals who created them. If a co-founder leaves without having assigned that work to the company, they can later claim rights in the product. The fix at formation is a founder IP assignment signed alongside the stock purchase agreement. The fix later is a confirmatory assignment, which depends on the departed founder’s cooperation and may cost something to obtain. Our post on who owns IP created by employees and contractors covers the default rules that apply when nothing was signed.

Contractors without assignment clauses

An agency or freelancer who builds your app, logo, or website owns the copyright unless a written agreement transfers it. A purchase order and an invoice do not transfer anything. Every contractor agreement needs a present-tense assignment of deliverables plus a confidentiality clause. For past work, ask the contractor to sign a short confirmatory assignment while the relationship is still friendly.

Brand mistakes

Choosing a name without a clearance search

Founders pick a name, buy the domain, print the merchandise, and only then learn that a company in an adjacent field has a federal registration for something confusingly similar. The result is a forced rebrand after the brand has started to mean something. A clearance search before commitment costs a fraction of that. The trademark search and clearance page describes what a proper search covers beyond a quick USPTO database check.

Waiting to file

Trademark rights in the United States come from use, but a federal application sets a nationwide priority date and is the document buyers and investors ask for. An intent-to-use application can be filed before launch. Companies that wait until after launch risk being beaten to the filing by someone who saw the product announcement.

Filing in the wrong name

Applications filed in a founder’s personal name, a predecessor entity, or an overseas parent create ownership questions that diligence will flag. The operating company should be the applicant, and any transfer should be recorded at the USPTO with an assignment of the goodwill.

Software and content mistakes

Open-source license contamination

Developers pull in libraries without checking the license. Permissive licenses are usually fine. Copyleft licenses such as the GPL and AGPL can require the company to release its own source code if the library is combined with proprietary code in certain ways, and a buyer’s code scan will find them. Adopt an open-source policy early, keep a bill of materials for each product, and review any copyleft component with counsel before it ships. Replacing a library is simple at month three and painful at month thirty.

Skipping copyright registration for core assets

Copyright is automatic, but registration is required before suing on a U.S. work and is the gateway to statutory damages and attorney’s fees. Registering the core codebase, the website, and key content around launch is inexpensive and keeps the enforcement option open. For software, the deposit rules allow trade secret portions to be redacted, as our post on copyright registration for software explains.

Maintenance and enforcement mistakes

Letting registrations lapse

A U.S. trademark registration requires a Section 8 declaration of continued use between the fifth and sixth anniversary, and a combined Section 8 and 9 renewal every ten years. Miss the window and the registration is cancelled. Calendar every deadline the day the registration issues, and assign someone to own the calendar. Our IP portfolio management page describes how that docket is maintained.

Ignoring a cease and desist letter

A demand letter in the inbox is easy to dismiss as a bluff. Some are. Many are the last step before a complaint is filed, and silence removes any chance of a negotiated outcome. Read our post on what to do when you receive a cease and desist letter before deciding to do nothing.

Treating confidential information casually

Trade secret protection depends on reasonable measures. Sharing the roadmap with a partner without an NDA, giving every employee access to every repository, and letting departing staff keep their laptops for a few weeks each chip away at the claim that the information was ever treated as secret. The fixes are policy-level: NDAs as a precondition to any sensitive conversation, role-based access, and an offboarding checklist that revokes access on the last day.

An annual review that catches these IP mistakes

None of these items takes long to check. Once a year, confirm that every person who has touched the product has signed an assignment, that every registration is in the operating company’s name and its deadlines are calendared, that the open-source inventory is current, and that NDAs are on file for every outside party who has seen confidential material. Doing that review before a raise or a sale, rather than during it, is the difference between a clean schedule and a list of closing conditions.
