Legal Definitions - Patent Act of 1952

The Patent Act of 1952 is a landmark federal law in the United States that comprehensively governs the granting and enforcement of patents. It significantly revised and codified existing patent statutes, establishing the detailed legal framework for what can be patented, the process for obtaining a patent, the rights conferred by a patent, and the remedies available for patent infringement. This Act introduced key concepts and definitions that remain central to U.S. patent law, including the requirements for novelty, non-obviousness, and utility for an invention to be patentable. It also clarified the different types of patents, such as utility, design, and plant patents.

Here are some examples illustrating the application of the Patent Act of 1952:

• Scenario: An independent inventor develops a novel algorithm that significantly improves the efficiency of data compression for streaming video. She wants to protect her invention from being copied by others.

  Illustration: The inventor would apply for a utility patent under the provisions of the Patent Act of 1952. The U.S. Patent and Trademark Office (USPTO) would examine her application to ensure her algorithm meets the Act's criteria for patentability, such as being new (novel), not obvious to someone skilled in the art (non-obvious), and having a practical use (utility). If granted, the patent would give her exclusive rights to her invention for a set period, as defined by the Act, allowing her to prevent others from making, using, or selling her patented algorithm without permission.

• Scenario: A medical device company holds a patent on a unique surgical instrument that allows for minimally invasive procedures. A competitor company begins manufacturing and selling a very similar instrument, claiming it's different enough to avoid infringement.

  Illustration: The original medical device company could file a lawsuit for patent infringement against the competitor. The legal proceedings would be governed by the Patent Act of 1952, which defines what constitutes infringement and outlines the remedies available to the patent holder, such as an injunction to stop the infringing activity and monetary damages for lost profits due to the competitor's unauthorized sales.

• Scenario: A university botanical research team successfully breeds a new, distinct variety of drought-resistant corn that produces higher yields than existing varieties.

  Illustration: To protect this new plant variety, the university could seek a plant patent, one of the specific types of patents established and defined by the Patent Act of 1952. This would grant the university exclusive rights to reproduce, sell, or authorize others to sell the new corn variety, preventing unauthorized propagation or sale by agricultural competitors for the duration of the patent.
