Patent Applications and Infringement from Soup to Nuts
An ideal patent document follows the rules in the Code of Federal Regulations (CFR) volume 37 because the application becomes the text of the patent. The first page of the document is the title page. It includes the name of the country issuing the patent, the patent number, the last name(s) of the inventor(s) and the date of the issuance of the patent. Internationally accepted codes called International Numbers for Identification of Data (INID) identify the bibliographic information. The title of the invention is found on the second page.
The following parts of a patent application (also known as a specification) work together to provide a full and clear understanding of the invention and its novelty, scope, and application.
- Title: The title of the invention, which should be concise and descriptive.
- Abstract: A brief summary of the invention, usually about 150 words, describing the invention’s nature, purpose, and benefits.
- Background of the Invention: This section provides context, explaining the problem or need the invention addresses and the prior art (existing technologies or solutions) that it improves upon.
- Summary of the Invention: A more detailed description of the invention, outlining its key features and advantages over existing technologies.
- Brief Description of the Drawings: An overview of the drawings included in the patent application, explaining what each drawing represents.
- Detailed Description of the Invention: A comprehensive explanation of the invention, including its components, operation, and use, often with reference to the accompanying drawings.
- Claims: The legal definitions of the invention’s scope, detailing the aspects of the invention that are considered novel and for which protection is sought.
- Drawings: Visual representations of the invention, such as diagrams or flowcharts, which are referred to in the detailed description and claims to help clarify and illustrate the invention.
The Claims section is often considered the most important portion of a patent application because it defines the scope and boundaries of an invention. Claims use highly technical language that are usually written by qualified registrants of the patent office with much experience crafting claims.
There are two types of claims:
1) Independent claims stand on their own and do not rely on language incorporated from any other claim.
2) Dependent claims incorporate the features of one or more of the preceding claims by reference, and they add a further limitation or condition.
Claims identify the “metes and bounds” of a patent and are typically the focus of most infringement litigation. When a patent is granted, infringement is based on the wording of the claims.
If an inventor believes his or her invention is an improvement or a different way to accomplish the same thing that is described in a patent, a new patent may be obtained. But if the improvement is too close or of a person with “ordinary skill in the art” only sees a marginal or obvious improvement, a claim of infringement may be made.
Patent infringement consists of “unauthorized making, using, offering for sale, or selling any patented invention within the United States, or importing into the United States any patented invention during its term.” You the patent owner may sue in federal court to stop the infringement and ask for financial damages.
Accused infringers may argue that their actions do not constitute infringement. Determining infringement primarily involves comparing the language of the patent claims to an accused product or process. The parties might hire expert witnesses to help the court understand the issues.
Although U.S. patents are presumed valid, a common defense to an accusation of infringement is to argue that the patent in question is invalid. A federal court makes the final decision.
The United States Patent and Trademark Office (USPTO) has no jurisdiction over infringement questions. In examining patent applications, the USPTO does not determine whether the invention sought to be patented may infringe a product or process. An invention may be able to be patented, but might also be covered by a prior unexpired patent, since a patent does not grant the right to use an invention.
The U.S. government may use any patented invention without permission of the patent owner, but the owner is entitled to compensation for such use.
Global competition in the pharmaceutical business and medical device industry is intense because many companies rely on patents to expand their proprietary product line so that profits may continue to flow into the organization. Leaders in science and industry watch for new inventions of promise and often capitalize on these products to maintain their perception as an innovator. But the key source of gratification for many successful patents is that they have improved the life of people in need of a solution.
