What are the types and parts of a patent

How To Write A Patent.

There are three main types of patents in the United States: utility patents, design patents, and plant patents.

Each type of patent has different requirements, durations, and fees.

  • Utility patents protect the functional aspects of an invention, such as a machine, a process, or a composition of matter. Utility patents last for 20 years from the date of filing, and require payment of filing fees, examination fees, search fees, issue fees, and maintenance fees.
  • Design patents protect the ornamental appearance of an invention, such as the shape, color, or surface features. Design patents last for 15 years from the date of grant, and require payment of filing fees, examination fees, search fees, and issue fees.
  • Plant patents protect new and distinct varieties of plants that are asexually reproduced. Plant patents last for 20 years from the date of filing, and require payment of filing fees, examination fees, search fees, issue fees, and maintenance fees.

Each type of patent consists of several parts that describe and define the invention in detail. The main parts of a patent are:

  • Specification: The specification is the written description of the invention that explains its background, purpose, advantages, embodiments, operation, and best mode. The specification should be clear, concise, and complete.
  • Drawings: The drawings are the visual representations of the invention that show its features and structure. The drawings should be consistent with the specification and comply with the rules and standards of the patent office.
  • Claims: The claims are the legal statements that define the scope and boundaries of the invention. The claims should be clear, concise, and supported by the specification and drawings.
  • Oath or declaration: The oath or declaration is a sworn statement that confirms that you are the original inventor or assignee of the invention.

What are the requirements and criteria for patentability

To obtain a patent for your invention, you need to meet certain requirements and criteria for patentability. These are:

  • Novelty: Your invention must be new and not previously disclosed to the public by you or others.
  • Non-obviousness: Your invention must not be obvious to a person having ordinary skill in the art (PHOSITA) at the time of your invention.
  • Utility: Your invention must have a useful purpose and function.
  • Ornamentality: Your invention must have an aesthetic appeal and not be dictated by function (for design patents only).
  • Enablement: Your invention must be described in sufficient detail to enable a PHOSITA to make and use it without undue burden or experimentation.
  • Written description: Your invention must be described in such a way that it shows that you had possession of it at the time of filing.
  • Definiteness: Your invention must be defined with clarity and precision to avoid ambiguity or confusion.

How to conduct a prior art search and analysis

Before writing your patent application, you should conduct a prior art search and analysis to identify existing patents or publications that are relevant to your invention. A prior art search can help you:

  • Determine if your invention is novel and non-obvious
  • Avoid wasting time and money on pursuing an unpatentable invention
  • Narrow down your claims and avoid unnecessary rejections or objections
  • Learn from previous inventions and improve your own

To conduct a prior art search, you can use various tools and databases to search for patents or publications by keywords, classifications, inventors, assignees, dates, etc. Some examples of tools and databases are:

  • Google Patents
  • USPTO Patent Full-Text and Image Database
  • USPTO Design Search Code Manual
  • Espacenet
