6 IP Mistakes That Kill Your Startup’s Valuation When Investors Come Looking

Key Takeaways IP issues are among the most common reasons investment deals slow down, restructure, or collapse entirely. Every mistake on this list is preventable, but only if it is identified and corrected before due diligence begins. ●     A startup without a registered trademark does not legally own its brand name at the national level, which is a direct red flag for investors ●     IP created by founders before the company was legally formed must be formally assigned to the company through a written agreement ●     Paying a contractor for work does not transfer ownership of what they created without a specific written IP assignment or work-for-hire agreement ●     Prior employment contracts may give a founder’s previous employer a legal claim over IP developed during that employment ●     Trade secrets lose legal protection the moment a company fails to take documented steps to maintain their confidentiality

 

A Chicago startup had strong revenues, a solid product, and a team with real experience. A Series A investor’s due diligence process took three weeks. At the end of it, the deal was restructured at a significantly reduced valuation because of what the IP review uncovered.

No federal trademark registration. No formal IP assignment agreement between the co-founders and the company entity. Three contractors who had built core product features and never signed an IP agreement. A prior employment contract that one founder had never reviewed with an attorney.

None of these problems were unfixable. But fixing all of them under the time pressure of an active investment process is far more expensive than addressing them before fundraising conversations begin.

Here are the six IP mistakes investors find most consistently in early-stage startups, and what you need to do about each one before someone starts writing a check.

Mistake 1: Not Registering the Trademark Before Raising Capital

A startup without a registered federal trademark does not legally own its brand name at the national level. Any competitor could file a similar name with the USPTO and establish priority over the startup in states where it has not yet operated. From an investor’s perspective, that is an unquantified risk sitting directly inside the asset they are considering funding.

Why Investors Care About Trademark Registration

Investors funding a consumer brand, a SaaS product, or any business with meaningful brand equity need to know that brand is legally protected. If the trademark is unregistered, the investor’s capital may go toward building recognition for a name the company does not legally own nationally. A subsequent infringement claim or forced rebrand post-investment depletes the very capital the investor just committed.

For startups heading toward acquisition, the issue is even more direct. Acquirers conducting IP due diligence treat an unregistered trademark as a valuation discount item. The acquiring company’s legal team flags it, the negotiation reopens, and the founder loses leverage at exactly the wrong moment.

We cover what the trademark registration process involves and the timelines to expect in our post on how long trademark registration takes, which is worth reviewing before planning your fundraising calendar.

What to Do Before Your First Investor Conversation

File your federal trademark application before your first substantive investor meeting. The filing date establishes your nationwide priority even before the registration certificate arrives, which typically takes 10 to 14 months. An application in progress is meaningfully better than no application at all from an investor’s standpoint, because it demonstrates that the founding team treats IP as a business asset.

If you are concerned your mark might face a refusal during examination, a professional clearance search before filing identifies conflicts early and gives you time to address them. Our post on why trademark applications get rejected covers the most common refusal grounds and how they are resolved.

Mistake 2: IP Was Never Formally Assigned to the Company

This is the mistake that surprises most founders, because it seems impossible. Of course the company owns what the founders built. They are the company. But under U.S. law, intellectual property belongs to the individual who created it unless it is formally transferred to another entity in writing. The fact that the individual is also the company’s founder does not change this.

The Founder IP Gap

If a co-founder wrote the original code, designed the brand, or developed the core methodology before the company was legally incorporated, that IP legally belongs to them as an individual, not to the company. If that founder later leaves, or if the relationship between co-founders deteriorates, the IP they created can become the subject of a legal dispute that directly affects the company’s ability to operate and the validity of investor ownership stakes.

Investors reviewing a startup during due diligence look specifically for signed IP assignment agreements from every founder. If those agreements do not exist, the investor’s legal team flags the company as having uncertain ownership over its own core assets.

Why This Problem Is Bigger Than It Looks

The IP assignment gap is not limited to code or brand assets. It extends to any invention, design, written content, or proprietary methodology that a founder developed in connection with the business, whether before or after its formation. A co-founder who contributed to product design without signing an IP assignment agreement may retain personal ownership over those contributions.

The fix is an IP assignment agreement that clearly transfers all relevant intellectual property from each founder to the company, signed at or before the formation of the company entity. For startups that have already passed formation without these agreements in place, retroactive IP assignments are legally possible but more complex, and they should be reviewed by an attorney before signing.

Mistake 3: No IP Agreements With Contractors or Freelancers

Startups in their early stages rely heavily on contractors and freelancers. A designer built the brand identity. A developer built the MVP. A writer created the marketing content. In many cases, none of these people signed a proper IP agreement before starting work.

The Work-For-Hire Misconception

The most common assumption founders make is that paying someone for work means the company owns what they produced. Under U.S. copyright law, that assumption is wrong. The legal default is that the creator of a work owns the copyright in it. Payment for the work does not transfer ownership unless one of two conditions is met: either the work qualifies as a “work made for hire” under the Copyright Act, or the creator has signed a written agreement explicitly assigning the rights to the company.

For freelancers and independent contractors, the “work made for hire” category is narrow and applies only in specific circumstances defined by the statute. In most standard freelance situations, the creator retains copyright ownership unless a written assignment is signed.

Did You Know? Under 17 U.S.C. § 101 of the Copyright Act, a “work made for hire” includes a work prepared by an employee within the scope of employment, and in certain specified categories, a work specially ordered or commissioned if the parties expressly agree in a written instrument signed by them that the work shall be considered a work made for hire. For independent contractors, this category is limited to specific types of commissioned works listed in the statute. Work falling outside these categories does not qualify as work made for hire regardless of any payment made.

What These Agreements Must Include

Every contractor, freelancer, agency, or consultant who created anything connected to your business should have signed an IP assignment agreement at the start of the engagement. This agreement should clearly identify the work being performed, assign all intellectual property rights in that work to the company upon creation, cover any derivative works or improvements developed during the engagement, and include a waiver of moral rights where applicable.

For startups that have already worked with contractors without these agreements in place, the same individuals may need to be approached to sign retroactive assignments. Some will cooperate readily. Others may require negotiation or compensation. Either way, this is significantly easier to address before a due diligence review than during one, when the investor’s legal team has already identified the problem and is factoring it into their valuation.

Mistake 4: Prior Employer IP Obligations Were Never Reviewed

This is the mistake with the most serious potential consequences, because it can put a cloud of third-party ownership over the startup’s most valuable assets. If a founder built the company’s core technology or methodology while still employed elsewhere, or using resources from a previous employer, that employer may have a legitimate legal claim over what was created.

When a Previous Employer Can Make a Claim

Most employment contracts in technology companies, law firms, financial institutions, and any innovation-driven industry contain IP assignment clauses. These clauses assign to the employer all intellectual property developed by the employee during the course of employment, and in many contracts, all IP developed using the employer’s resources, on the employer’s time, or related to the employer’s business, regardless of when or where it was created.

A founder who left a corporate role and began developing a product in the same technology space, using knowledge and methods developed during that employment, may be in a position where the previous employer has a colorable legal claim over some or all of what was created. This risk does not have to be certain to be damaging during due diligence. The investor’s legal team only needs to identify it as a plausible risk to pause or restructure the deal.

How to Audit Founder IP Obligations Before Raising

Every co-founder should have their previous employment agreements reviewed by an IP attorney before the startup begins fundraising conversations. The review should identify any IP assignment clauses, non-compete provisions, non-solicitation obligations, and confidentiality requirements that could affect the startup’s ownership or operation.

If a risk is identified, there are several approaches available depending on the specific language of the agreement and the nature of the technology involved. In some cases, the relevant IP can be ring-fenced or redesigned to remove the prior employer connection. In others, the prior employer may be willing to provide a written waiver. Acting on these issues before investors are in the picture gives the founder far more options than addressing them during an active deal negotiation.

This kind of IP ownership complexity is also a central concern when evaluating a business for acquisition. Our post on how to verify the IP you are actually getting when buying a business covers the same analysis from the acquirer’s side, which is useful context for any founder preparing their own IP for scrutiny.

Mistake 5: No Legal Framework Protecting Trade Secrets

Not every valuable business asset can be trademarked or patented. Customer lists, pricing models, proprietary algorithms, sales playbooks, manufacturing processes, and internal business methodologies may all constitute trade secrets. But trade secrets only receive legal protection when the company has actively taken steps to keep them confidential.

What Qualifies as a Trade Secret Under Illinois Law

Under the Illinois Trade Secrets Act (ITSA), a trade secret is information, including a formula, pattern, compilation, program, device, method, technique, or process, that derives independent economic value from not being generally known, and that is subject to reasonable efforts to maintain its secrecy.

Two elements are both required: the information must have commercial value from being secret, and the company must have taken reasonable measures to protect that secrecy. If either element is missing, trade secret protection does not apply under Illinois law.

For startups in Illinois and for those operating across multiple states, federal protection under the Defend Trade Secrets Act (DTSA) adds a federal civil remedy for trade secret misappropriation that operates alongside state law.

Quick Insight! The Illinois Trade Secrets Act (765 ILCS 1065/2) defines a trade secret as information that derives independent economic value from not being generally known or readily ascertainable by proper means, and is subject to reasonable efforts to maintain its misappropriation of qualifying trade secrets. Failure to take reasonable secrecy measures disqualifies the information from protection regardless of its commercial value. The Act provides civil remedies including injunctive relief and damages for

 

What Protection Actually Requires

Taking reasonable measures to protect trade secrets means more than simply treating information as confidential internally. Investors reviewing a startup’s trade secret framework look for documented, systematic practices including non-disclosure agreements with all employees, contractors, and business partners who have access to sensitive information; restricted access controls limiting who within the organization can view specific proprietary data; documented internal policies identifying what information is classified as confidential; and physical or digital security measures appropriate to the nature of the information.

A startup with genuinely valuable trade secrets but no documented protection measures faces a serious due diligence problem. The investor cannot rely on trade secret law to protect those assets if the company has not established the practices that law requires.

Mistake 6: Leaving Every IP Problem for Due Diligence to Uncover

The most expensive version of every mistake above is discovering it during an investor’s due diligence review. This is where the financial cost multiplies and where the founder loses negotiating leverage at the most critical stage of the deal.

Why This Is the Most Damaging Timing

When an IP problem is identified during due diligence, the founder is in the weakest possible negotiating position. The investor has already committed legal resources, financial modeling, and often significant time and management attention to the deal. They have leverage. They use IP problems identified in due diligence in one of three ways: to reduce the valuation, to impose more restrictive deal terms including additional founder representations and warranties, or in serious cases, to walk away from the deal entirely.

Fixing IP problems under active time pressure from an investor also costs more in legal fees than fixing them proactively. An attorney working against a deal timeline is billing for urgency as well as expertise.

What a Pre-Investment IP Audit Covers

A pre-investment IP audit is a structured review of everything the company owns, how it is protected, where the gaps are, and what needs to be addressed before the company presents its IP portfolio to investors or an acquirer.

For startups in Chicago, across Illinois, and in Washington D.C., a pre-investment IP audit with Drishti Law covers trademark registration status and clearance, IP assignment agreements for all founders and key contractors, prior employment IP obligation review, trade secret protection framework assessment, and copyright ownership verification across all key company assets.

The startups that command the strongest valuations in Chicago’s investment community treat IP as infrastructure built in advance, not as a checklist to work through under pressure when a deal is already in motion. Addressing these six mistakes before fundraising begins is one of the highest-return legal investments a founder can make.

For startups that are also building toward a public market, these same IP foundations directly affect the strength of the disclosures required in the initial public offering process and the level of comfort an underwriter will have with the company’s IP position.

Frequently Asked Questions

Q1: Do I need a patent to have strong IP for investor due diligence purposes?

Not necessarily. Investors in most startup categories care far more about clear IP ownership documentation than about patents specifically. A startup with a registered trademark, proper IP assignment agreements, enforceable trade secret protections, and clean contractor agreements presents a stronger IP position than one with a filed patent but unclear ownership documentation across the rest of its IP portfolio.

Q2: At what stage should a startup start thinking about IP protection?

Before the first product launch and ideally at company formation. IP problems almost always originate in the earliest stage of a startup when founders are moving quickly and legal paperwork feels like a distraction. The longer these issues go unaddressed, the more difficult and expensive they become to correct, particularly as the company adds employees, contractors, investors, and commercial relationships that complicate retroactive fixes.

Q3: Can a startup fix IP problems after receiving a term sheet from an investor?

Fixes are possible after a term sheet is issued, but the leverage dynamic is unfavorable. The investor knows about the problems, their legal team is actively tracking them, and any correction made under that timeline is visible to the investor and factors into their negotiating position. Addressing IP problems before any investor engagement begins means the startup never has to explain them at all.

Q4: What is the difference between an IP assignment agreement and a non-disclosure agreement?

An IP assignment agreement transfers ownership of intellectual property from a creator to the company. It determines who legally owns what was built. A non-disclosure agreement creates a confidentiality obligation that prevents the other party from sharing or misusing proprietary information. Both are necessary but serve different legal purposes. A contractor can sign an NDA and still retain copyright in their work if no IP assignment was included.

Q5: What happens to IP if a co-founder leaves the company before an investment round closes?

A departing co-founder retains ownership of any IP they created that was not formally assigned to the company before departure. If IP assignments were not in place, the departing founder may own legally significant portions of the company’s core assets. This is one of the most serious due diligence problems investors encounter.
