Business Law
Intellectual property law covers four distinct systems: patents, trademarks, copyrights, and trade secrets. Each protects something different, works through a different legal mechanism, costs a different amount to obtain and maintain, and requires different behavior from you to stay effective.
Most entrepreneurs interact with all four — often without realizing it. This article explains what each one covers, what it actually costs, and how founders typically prioritize them in the early stages of building a company.
They are not interchangeable. You cannot patent a logo, trademark a novel, copyright a manufacturing process, or trade-secret a publicly disclosed invention. Understanding what each covers determines which one applies to what you have built.
A utility patent protects a novel, non-obvious, and useful invention — the how and what of making something work. A design patent protects the ornamental appearance of a functional item. A plant patent is narrow and covers asexually reproduced plant varieties.
A patent gives you the right to exclude others from making, using, selling, or importing your invention in the United States for the patent's term. It does not give you the right to practice the invention yourself — your invention might still infringe someone else's patent. What it gives you is exclusionary power against competitors.
The patent process runs through the United States Patent and Trademark Office (USPTO). A full utility patent application takes two to four years to prosecute and, with attorney fees and USPTO fees, typically costs $10,000 to $30,000 or more for a moderately complex invention. Highly complex technologies (biotech, semiconductors) run higher.
A provisional patent application is a lower-cost first step — typically $2,000–$5,000 with an attorney — that establishes your priority date and lets you use "Patent Pending" for 12 months. During that year you need to file the full non-provisional application or lose your priority date.
"Patent Pending" has real commercial value: it signals to competitors and investors that you have filed, and it deters copying while your application is under review. The term expires when the patent issues or the application is abandoned.
Utility patents have a 20-year term from the filing date of the non-provisional application. After that, the invention enters the public domain. USPTO also requires maintenance fees at 3.5, 7.5, and 11.5 years after issuance — failing to pay them abandons the patent.
In the United States, you have a one-year grace period from the date of first public disclosure to file a patent application. Outside the U.S., most countries operate on absolute novelty — any public disclosure before filing destroys patentability. If you plan to pursue international protection, file before you publish, present, or sell.
A trademark identifies the source of goods or services and distinguishes them from competitors. It can be a word (your company name), a logo, a slogan, a color, a sound, or a combination. The stronger the mark — fanciful or arbitrary marks like made-up words — the stronger the protection. Descriptive marks are harder to protect and generic terms cannot be trademarked at all.
Federal trademark registration through the USPTO gives you nationwide priority, the right to use the ® symbol, and a presumption of ownership that strengthens enforcement. Common law trademark rights (unregistered) arise from use in commerce but are limited geographically to where you actually operate.
A federal trademark application costs $250–$350 per class of goods/services in USPTO filing fees, plus attorney fees of $1,500–$3,000 for a straightforward application. The process takes 8–12 months on average. You should conduct a clearance search before filing — filing on a mark that conflicts with an existing registration wastes money and creates infringement exposure.
Federal trademarks require renewal filings between years 5–6 and again between years 9–10, then every 10 years after that. They can last indefinitely as long as you continue using the mark in commerce and file the required renewals. Abandonment — stopping commercial use — can invalidate the registration.
Copyright protects original works of authorship fixed in a tangible medium. This includes written content, software code, website design, photographs, artwork, music, and video. Copyright does not protect ideas, facts, systems, or methods — only the specific creative expression of them.
Copyright attaches automatically when you create an original work — you do not need to register or use a © symbol. However, registration with the U.S. Copyright Office significantly strengthens your enforcement position. Without registration, you can only recover actual damages (often difficult to prove) in an infringement lawsuit. With registration made before infringement or within three months of publication, you can seek statutory damages (up to $150,000 per willful infringement) and attorney's fees.
Copyright registration costs $45–$65 per work filed online. For a small business with significant creative output — a blog, a software product, a design portfolio — registration is a low-cost way to preserve enforcement rights.
If you hire contractors to create content, code, or design work for your business, copyright in that work does not automatically belong to you. You need a written work-for-hire agreement or an assignment of copyright rights. Without it, the contractor may own the copyright to work you paid for.
For works created by individuals, copyright lasts for the author's life plus 70 years. For works made for hire (created by employees within the scope of employment, or by contractors under a qualifying work-for-hire agreement), the term is 95 years from publication or 120 years from creation, whichever expires first.
A trade secret is any business information that derives economic value from not being publicly known and that you take reasonable steps to keep confidential. The Coca-Cola formula is the textbook example. For entrepreneurs, trade secrets typically include: proprietary algorithms or processes, customer and pricing data, supplier relationships, business methods, and any information that gives you competitive advantage because competitors do not have it.
Unlike patents, trade secrets have no registration process and no government involvement. Protection is indefinite as long as the information remains secret. That is both the advantage and the vulnerability.
Trade secret protection requires active effort. Courts look at whether you took "reasonable measures" to maintain secrecy. At minimum, this means:
If you do not take these steps and someone discloses or uses the information, you may have no recourse. Trade secret protection is forfeited by the owner's failure to protect — not just by the misappropriator's act.
For some inventions, trade secret protection is preferable to a patent. A patent requires public disclosure of the invention (the specification becomes public upon publication of the application). A trade secret can last forever — but only if it stays secret. If a competitor independently discovers or reverse-engineers your process, you have no recourse. If a competitor steals it, the Defend Trade Secrets Act (DTSA) gives you a federal cause of action.
The trade secret vs. patent question turns on: How long will your competitive advantage last? If it is likely to be obsolete before a patent issues or expires, trade secret protection may be more practical. If it is foundational and defensible for 20 years, a patent gives you exclusionary power that trade secret law does not.
Most early-stage founders prioritize in this order:
Every founder should sign an IP assignment agreement before the company is formally organized — or immediately after. This document assigns to the company all IP created by the founder in connection with the business, including work done before the company was incorporated. Without it, IP that a co-founder created personally may belong to them, not the company — a catastrophic problem when investors conduct due diligence or when co-founders part ways.
The same principle applies to employees and contractors from day one. IP assignment language should be in every offer letter and every contractor agreement.
