Patent Trolls Explained: The Abuse of the US Patent System

The United States Patent and Trademark Office (USPTO), a federal agency within the Department of Commerce, promotes innovation and economic growth by examining and granting patents to qualifying inventions (which must be novel, useful, and non-obvious) and registering trademarks to protect business brand identities; it maintains public databases for patent and trademark searches, provides educational resources on intellectual property rights, advises government officials on IP policy, resolves disputes through specialized boards, collaborates internationally under treaties like the Patent Cooperation Treaty, and operates as a self-sustaining entity funded entirely by user fees rather than taxpayer dollars.

The US patent system, established under the Constitution's intellectual property clause, has been fundamental to American innovation and economic growth by democratizing invention, providing incentives for innovation through property rights, enabling technology transfer through licensing, and serving as a gold standard due to its technology-neutral, owner-neutral approach with low barriers to entry and strong enforcement mechanisms.

The U.S. Patent and Trademark Office (USPTO) promotes innovation by protecting intellectual property through patents and trademarks, which incentivizes investment and prevents theft; the agency actively expands access to innovation resources through initiatives like the Women Entrepreneurship Initiative, pro bono legal services, and educational programs like Camp Invention, recognizing that broadening participation in the innovation ecosystem—particularly among underrepresented groups such as women and military veterans—can significantly boost economic growth, with research suggesting that quadrupling female inventor participation could increase GDP by one trillion dollars.

The United States Patent and Trademark Office (USPTO) is America's foremost innovation agency dedicated to fostering innovation and driving economic growth while maintaining a reliable, predictable, and high-quality intellectual property system. The USPTO accomplishes this mission by issuing patents that grant holders exclusive rights to their inventions and by registering trademarks and service marks for products and services. In fiscal year 2023, the USPTO had over 13,000 employees, including approximately 8,000 patent examiners, 700+ trademark examining attorneys, 225 administrative patent judges, and 28 administrative trademark judges. The office received over 650,000 patent applications, with about 340,000 issued as patents, and over 700,000 trademark applications, with more than 400,000 certificates of registration issued.

The United States Patent and Trademark Office (USPTO) serves as America's Innovation Agency, fostering innovation that changes the world over 200 years. Its mission is to drive U.S. innovation and global competitiveness for American benefit, with a vision to unleash America's potential by helping inventors protect their ideas. Goals include promoting efficient IP rights delivery, protecting IP against threats, bringing innovation to public good, and maximizing operational effectiveness. Patent examiners, skilled engineers and scientists, work with entrepreneurs to process applications and grant patents, creating jobs and expanding commerce while protecting intellectual property.

In US civil litigation, discovery—the process where parties obtain and disclose evidence before trial—encourages settlement through two mechanisms: first, by revealing the strengths and weaknesses of each party's case, enabling rational risk assessment (as demonstrated when Patty evaluates her 60% chance of losing $100,000 versus paying $50,000 to settle); second, by creating substantial time and monetary costs that incentivize parties to resolve disputes before completing discovery, thereby avoiding further expenses while achieving a mutually acceptable outcome.

Civil cases can be filed by anyone without government approval or evidence, requiring only a legal theory with basis in fact and law. A defendant is not officially a defendant until served with the complaint and summons, and they don't have to answer or appear until then. Civil cases lack constitutional rights like criminal cases: no speedy trial rule, no Fifth Amendment protection against self-incrimination (which can be used against you), and no Sixth Amendment right to counsel. To file a civil case, you only need to allege in good faith that a contract existed, a provision was violated, and that caused injury. A complaint is not evidence—it's just allegations. Civil cases can include counterclaims by defendants and third-party claims. Dollar amounts in complaints usually mean nothing legally. Most of a civil case is discovery, where parties exchange information. Once a case is filed, both parties have subpoena power for third parties without approval. Discovery disputes show up on the docket but don't indicate who will win. Civil cases can be resolved at any time through settlement, similar to plea bargains in criminal cases. Settlement discussions are mandated by courts because judges are busy and trials are expensive. Before a civil trial in the United States, parties must have a formal mediation with an impartial third-party mediator. Settlement discussions and offers are highly confidential, with lawyers, clients, and mediators signing non-disclosure agreements.

This section covers the practical aspects of civil litigation. Key topics include: (1) Initiating lawsuits - the notice of civil claim is the first document filed, outlining claims and parties; (2) Court parties - the defendant files the response to civil claim, while the plaintiff initiates the action; (3) Adversarial trial process - parties present opposing viewpoints to an impartial trier of fact; (4) Discovery process - allows parties to assess strengths and weaknesses of their positions, explaining why most claims settle out of court; (5) Stare decisis - the doctrine that courts follow precedent for consistency and predictability.

The cost of litigation in the United States is prohibitively high for most individuals. Initial attorney consultations require a $5,000 upfront payment, with hourly rates averaging $600 or more. Initial court proceedings typically cost between $20,000 and $50,000. Expert witnesses add another $20,000 or more. Filing a lawsuit costs approximately $100,000 per party. Even small claims cases (such as neighborhood disputes or workplace issues) can cost $250,000 or more. Divorce cases can cost up to $1 million or more. These costs explain why most Americans avoid litigation for minor matters.

Civil trials involve private parties suing each other, unlike criminal trials where the state prosecutes. The parties differ: criminal trials are 'state versus defendant,' while civil trials are 'plaintiff versus defendant.' Settlement is common in civil trials, especially for famous individuals who cannot afford prolonged litigation. If a trial would be too costly or time-consuming, parties may negotiate settlements to avoid court proceedings. The threat of legal costs influences settlement negotiations, as losing parties must pay the winner's legal fees. This creates financial incentives to settle rather than risk trial, even when the outcome might favor the plaintiff.

There is a distinction between NPEs and legitimate idea shops like Dolby Labs that create tangible innovations. The intent of the patent system is innovation resulting in new products with demand that drives the economy forward—not pure isolation. When practicing entities fight with each other, they are incited to innovate and patent to compete. However, when a practicing entity disputes with an NPE, the NPE is not competing for product space and has no liabilities, creating an incentive for the practicing entity to make itself smaller rather than innovate more. This dynamic could discourage innovation.

A non-practicing entity (NPE) is a company that derives a large proportion or most of its revenue from patent licensing rather than manufacturing products. This differs from the term 'patent troll,' which is used more narrowly to describe entities that acquire patents solely to sue others for infringement without contributing to innovation. Not all NPEs are negative; universities and major corporations like IBM and HP also license technology as their primary revenue source without being classified as patent trolls.

A patent troll, also known as a non-practicing entity (NPE), is someone who buys up patents not to build anything new, but purely to sue companies that are actually innovating. These entities weaponize the patent system by demanding settlements for alleged infringement, often using broad or vaguely worded patents. Their business model is built on litigation rather than innovation.

A patent troll is a person or company enforcing patent rights to collect licensing fees without manufacturing products or supplying services, engaging in economic rent-seeking. The term originated in 1993 and gained prominence in the late 1990s. Related terms include patent holding company and non-practicing entity. Patent trolling differs from legitimate NPEs like individual inventors and university labs. Patent trolling has been less prevalent in Europe due to its loser-pays costs regime, while the U.S. traditionally used the American rule where each party pays its own attorney's fees. In 2012, patent trolls filed over 2,900 infringement lawsuits nationwide. The Obama administration responded by directing the USPTO to require more specific patent disclosures, tighten scrutiny of overly broad claims, and curb lawsuits against consumers and small businesses. Vermont enacted the Consumer Protection Act prohibiting bad-faith threats with excessive fees. Minnesota obtained a settlement prohibiting MPHJ Technology Investments from continuing its licensing campaign. In 2011, U.S. business entities incurred $29 billion in direct costs from patent trolls, with NPE lawsuits comprising 61% of all patent cases by 2012.

Patent trolls are non-practicing entities (NPEs) who hold patents but don't make products covered by those patents. They extort payments from companies that do make such products, costing the US economy approximately $500 billion in the last 10 years. While annoying, patent trolls are less harmful than competitors using patents to maintain monopolies. Patent trolls want ongoing royalty payments, so they don't destroy their victims. Competitors seeking injunctions pose more existential threats to small companies.
