Most founders discover what they own at the worst possible moment — during due diligence, when a contractor who wrote core code never signed anything.
A founder I know discovered during due diligence that her company did not own its own product. A contractor had written the core engine in year one, been paid, and never signed anything assigning the intellectual property. Under default copyright rules, he still owned it.
He was reasonable about it. It still cost six figures and delayed the round by four months.
That is the recurring shape of business legal problems: they are cheap to prevent, expensive to fix, and they surface at the exact moment you can least afford them.
What actually needs a business lawyer
Entity formation and structure. LLC, S-corp, C-corp, partnership — each with different liability, tax and investment consequences. A C-corp in Delaware is standard for companies planning venture funding and needless overhead for a two-person consultancy.
Founder agreements. Before anything else. Equity split, vesting, what happens when someone leaves, who decides what. Companies fail over this more often than over product.
IP assignment. Every founder, employee and contractor signs an agreement assigning work product to the company. This is the failure in the story above and it is universal.
Employment documents. Offer letters, handbooks, contractor agreements, confidentiality terms.
Customer and supplier contracts. Terms of service, master service agreements, statements of work, licensing.
Financing documents. SAFEs, convertible notes, priced rounds, loan agreements.
Vesting protects you from your co-founder, and them from you
Standard founder vesting is four years with a one-year cliff. Without it, a co-founder who leaves after five months keeps their full equity stake permanently, and every future investor sees a large block owned by someone who does nothing. This clause has saved more companies than any other single document.
The four kinds of intellectual property
| Type | Protects | Duration | Registration |
|---|---|---|---|
| Patent | Inventions, processes, designs | Limited term from filing | Required — and expensive |
| Trademark | Brand names, logos, slogans | Indefinite while used and defended | Optional but strongly advisable |
| Copyright | Creative works, software code, content | Long — life plus decades | Automatic; registration adds remedies |
| Trade secret | Confidential business information | As long as it stays secret | None — protected by conduct |
Patents
A patent lawyer — or patent agent — must be registered with the patent office and typically holds a technical degree. This is one of the few areas of law with a formal admission requirement beyond a law licence.
Utility patents cover how something works, design patents how it looks. To be patentable an invention must generally be novel, non-obvious and useful.
Two things people get wrong. First, the claims are the patent. The description is context; the claims define what you own. A poorly drafted patent issues with claims so narrow that competitors design around them trivially — you paid full price for a certificate that protects nothing. This is why DIY filing is a false economy.
Second, public disclosure starts a clock. The US allows a limited grace period after your own disclosure; most other countries do not. Presenting at a conference or launching publicly before filing can permanently destroy international patent rights.
Cost is the honest constraint. A properly drafted utility patent application runs well into five figures with attorney fees, and international protection multiplies that. Provisional applications are cheaper and establish a filing date for twelve months, which buys time to assess commercial viability before committing.
Trademarks
A trademark attorney handles brand protection, and this is where most businesses should start — it is far cheaper than patenting and protects the asset customers actually recognise.
Rights arise from use in commerce in the US, but federal registration provides nationwide priority, the presumption of validity, and access to federal court.
The mistake that costs most: skipping the clearance search. Businesses build a brand, print signage, buy the domain, and then receive a cease and desist from someone with prior rights. Rebranding an established business costs vastly more than a search would have.
Choose a distinctive mark. Arbitrary and fanciful marks — invented words, or ordinary words unrelated to the product — are strongest. Descriptive marks are weak and may be unregistrable without proving acquired distinctiveness. A trademark lawyer will steer you away from the name you like toward the one you can actually own.
Registration is not the end. Trademarks require ongoing use, periodic maintenance filings, and active policing. Rights can be lost through abandonment or through becoming generic.
Copyright and trade secrets
Copyright attaches automatically to original works including software code, and lasts a long time. In the US, registration is required before suing for infringement and unlocks statutory damages and attorney fees — worth doing for core assets.
The critical rule for businesses is the one from the opening story. Work created by an employee within their role generally belongs to the employer automatically. Work created by an independent contractor generally does not, unless there is a written assignment. Every contractor agreement needs one.
Trade secrets protect confidential information with commercial value — customer lists, formulas, algorithms, pricing. Protection depends entirely on reasonable measures to keep it secret: NDAs, access controls, marking, exit procedures. Fail to take those measures and the protection evaporates.
The three documents every business should have from day one
1. An IP assignment signed by every founder, employee and contractor. 2. A confidentiality agreement covering anyone with access to sensitive information. 3. Written contractor agreements — not verbal arrangements with people you like and trust. The people you trust are exactly the ones you will not have documentation for.
Contracts that matter more than founders expect
Limitation of liability. Caps your exposure, typically at fees paid. Without it, a small contract can carry unlimited liability.
Indemnification. Who covers whom for third-party claims. Read the direction carefully — mutual indemnity is fair; one-way indemnity in the customer's favour is common in enterprise contracts and negotiable.
IP ownership. In service agreements, who owns deliverables and who retains pre-existing tools and libraries. Get this explicit.
Termination. How either party exits, with what notice, and what survives.
Dispute resolution. Which law applies, which forum, and whether arbitration is required. A contract enforceable only in a distant jurisdiction is functionally weaker than one enforceable locally.
Payment terms. Net terms, late fees, and the right to suspend service for non-payment.
What it costs, and when to spend
Business legal work ranges from a few hundred dollars for entity formation to five figures for a financing round. Reasonable sequencing for a small company:
- Formation and founder agreement
Before you build anything. The cheapest meaningful legal spend there is. - IP assignments
Immediately, for everyone who touches the product. - Trademark clearance search
Before printing anything or buying signage. - Template customer contract
Once, properly, then reuse. Far cheaper than bespoke drafting each time. - Trademark registration
Once the brand is settled and you have traction. - Patent
Only where there is a genuinely novel technical invention with commercial value justifying the cost.
Many business lawyers offer a fixed-fee startup package covering the first three or four items. Ask — it is usually better value than hourly work for standard documents.
Getting sued, and sending a cease and desist
Both sides of an IP dispute start with a letter, and both are handled badly by people acting on instinct.
If you receive a cease and desist: do not ignore it, do not respond emotionally, and do not immediately comply either. Ignoring it can support a claim of wilful infringement, which multiplies damages. Immediate compliance can concede a claim that was never strong. Send it to a lawyer and ask three questions — do they actually hold the rights they assert, does what we do fall within those rights, and what does compliance cost against fighting?
If you are sending one: a letter that overstates your rights can expose you to a declaratory judgment action filed in the recipient's home court, on their timetable. Have the rights verified first.
Trademark oppositions. Registration applications are published for opposition, and monitoring services alert you when someone files something similar. Opposition is far cheaper than litigation after a mark registers.
Takedown notices. For online copyright infringement, the DMCA process in the US and equivalents elsewhere are fast and cheap compared to court. Counter-notices exist too, and filing a false takedown carries liability.
Insurance covers more than people check
General liability policies frequently include advertising injury coverage, which can cover certain trademark and copyright claims. Specialist IP insurance exists separately. Check your policy before assuming a dispute is entirely self-funded.
The UK and international position
In England and Wales, business legal work is handled by solicitors, with patent attorneys and trade mark attorneys as separately regulated professions. Companies House handles incorporation; the UK Intellectual Property Office handles registrations.
IP is territorial, which is the point people miss most often. A US trademark registration does not protect you in the UK, the EU or anywhere else. International routes exist — the Madrid Protocol for trademarks, the PCT for patents — that streamline multi-country filing, but you still need protection in each market that matters.
If you sell internationally, file in your significant markets early. Trademark squatting in some jurisdictions is a real and expensive problem, and first-to-file systems do not care that you used the name first somewhere else.
Employment documents that prevent disputes
Beyond IP assignment, a few documents do most of the work in preventing employment disputes.
Written offer letters stating role, compensation, and employment status. Verbal promises about equity, bonuses or promotions become disputes with remarkable reliability.
Contractor agreements that reflect reality. Misclassifying employees as contractors creates back taxes, penalties and benefit liability. The label in the contract does not control — the degree of control you exercise does.
Confidentiality agreements covering anyone with access to sensitive information, including advisers and interns.
Restrictive covenants, carefully. Non-compete enforceability varies enormously and has narrowed significantly in several jurisdictions. Overbroad clauses are frequently struck out entirely rather than narrowed, taking the protection with them. Non-solicitation of customers and staff is generally more enforceable than a blanket non-compete.
An employee handbook setting expectations and complaint routes — useful evidence that policies existed and were communicated.
The summary
Get the entity, the founder agreement and the IP assignments done before you build. Search before you brand. Register the trademark once the brand is settled. Treat patents as a commercial decision, not a badge — file only where the claims will actually protect something worth the money.
And write down the arrangements with the people you trust most, because those are the relationships where nothing is ever documented and where the eventual dispute costs the most.
Keep the corporate housekeeping current
Annual filings, registered agent details, minutes of major decisions, an accurate cap table, and separate business banking. These sound like formalities and they are what preserves limited liability. Investors and acquirers examine them in diligence, and a company that cannot produce clean records discounts its own valuation.
When you actually need a lawyer versus a template
Being honest about cost, because legal spend competes with everything else in a small business.
Templates are fine for: a straightforward NDA, a simple contractor agreement for low-risk work, standard website terms and a privacy policy for a business without unusual data practices.
Templates are dangerous for: founder and equity agreements, anything involving investment, IP assignment where the IP is the business, contracts with liability exposure beyond the fee, and anything international.
The test is whether the downside is capped. A bad NDA costs you a confidentiality claim you might have won. A bad founder agreement costs you the company.
Frequently asked questions
What is the difference between a patent and a trademark?
A patent protects an invention or process for a limited term. A trademark protects a brand identifier — name, logo, slogan — and can last indefinitely while it is used and defended.
Do I need a patent attorney or can I file myself?
You can file yourself, and applications drafted without expertise routinely issue with claims so narrow they are commercially worthless. The drafting is the value, not the filing.
When should a startup hire a business lawyer?
Before the first co-founder agreement, the first contractor, and the first customer contract. Fixing ownership problems later costs more than preventing them.
