What is the process of patent examination?

In California, the process of patent examination is a complex one that starts when an application for a patent is submitted to the United States Patent and Trademark Office (USPTO). When the application is submitted, it is reviewed to make sure it meets the requirements of the Patent Act. This includes ensuring that the invention is new, useful, and non-obvious. If the application meets these criteria, it is then assigned to a patent examiner for review. The patent examiner then conducts a thorough examination of the patent application, such as by searching for prior art, to ensure that the invention meets the criteria of the Patent Act. The patent examiner will review the claims of the invention to see if they are properly supported by the description and drawings included in the application. The examiner will also analyze the prior art to ensure that the invention is not already known or obvious. Once the review process is complete, the patent examiner will issue an "office action" which states whether the patent can be granted or not. If the patent is granted, it is published by the USPTO and the inventor will receive a patent certificate. However, if the patent is rejected, the inventor has the option to file a response and argument against the decision. The patent examiner will then review the response and may still decide to grant the patent.
