Common Types Of IP Theft

IP theft takes many forms. Identifying the exact nature of a violation is a critical first step in any intellectual property litigation matter. Common violations include:

• Copyright infringement: Copyright protection covers original creative works – including written content, artwork, music and digital media. Infringement occurs when someone reproduces, distributes or displays these works without the rights holder’s permission.
• Trademark infringement: Trademarks protect a business’s name, logo and identifying marks. Infringement occurs when another party uses these marks without authorization in a way that causes consumer confusion or damages brand reputation.
• Patent infringement: Patents protect inventions and proprietary products. Infringement occurs when a party manufactures, sells or uses a patented invention without authorization from the patent holder.
• Trade secret theft and misappropriation: Trade secrets – including formulas, strategies and proprietary processes – represent some of a company’s most valuable assets. Misappropriation occurs when another party acquires or discloses these secrets through improper means.
• Stolen source code, software misuse and licensing violations: Software theft is a growing concern for modern businesses. This includes unauthorized copying of source code, using software beyond its licensed scope and distributing proprietary software without authorization.

Any of these violations can disrupt operations and cause lasting financial harm. Prompt legal action matters.
