Temporary patent application is a simple and cheap method, which can start to protect your invention when you fully enrich its invention, decide whether to apply for a complete patent or not, and conduct any market tests you may need. Both temporary patent applications and non-temporary patent applications are applicable to inventions that may eventually become the subject of utility model patents. If a non-provisional patent application for the same invention is filed within 12 months, the provisional application can guarantee the priority application date. Once the provisional application is submitted, the inventor has exactly one year (if the invention has not been published before) to submit a non-provisional application for the same invention. If the inventor fails to file a non-provisional application within the time limit, the provisional patent application will be deemed to have been abandoned. This means that the inventor lost the right of filing date, even lost the ownership when the invention was made public to the public more than a year ago. Submitting a temporary application can save inventors' upfront expenses and give them time to evaluate the commercial value of their inventions. They can also conduct research and seek funds, and then bear the cost and process of preparing non-temporary applications.
