Patent search

A patent search is a systematic review of published patents and related technical literature to determine whether an invention is new, unique and patentable. It identifies prior art that could affect patent filing, prosecution or enforcement.

Description

Patent searching is a critical first step in the innovation lifecycle. By analyzing existing patents, applications and scientific publications, organizations can gauge whether an idea meets the requirements of novelty and inventive step.

Searches are typically carried out by trained analysts using global patent databases, classification systems and specialized software. They help inventors, corporations and legal teams make informed decisions about filing strategy, freedom to operate and R&D investment. There are several common types of searches – novelty searches, freedom-to-operate searches, invalidity searches and state-of-the-art studies – each designed to answer a different strategic question.

Example use cases

  • Filing: Confirm that an invention is patentable before submitting an application.
  • Development: Identify existing technologies to refine design or avoid infringement.
  • Licensing: Assess the strength and scope of target portfolios.
  • Enforcement: Locate prior art to support or challenge patent validity.
  • Intelligence: Track competitor innovation trends and technology landscapes.
