Patent Approval


Getting a patent is a pivotal step for inventors aiming to protect their creations. However, a frequently asked question is, “how long does it take to get a patent?” This article delves into the nuances of the patent application process, offering insight into the duration, and patent approval time as well as the intricacies involved.

The Patent Application Journey

The journey to patent protection starts with submitting a patent application to the patent office. In the United States, this responsibility falls on the United States Patent and Trademark Office (USPTO). The filing of an application establishes your invention’s filing date, a critical timestamp in the world of intellectual property.

There are primarily two types of patent applications that you can file: a provisional patent application and a non-provisional patent application. The provisional one serves as a placeholder, granting a “patent pending status” for your invention for up to a year. Inventors often choose this route to secure an early filing date while refining their invention or seeking funding. However, to obtain a patent grant, they’ll need to follow up with a non-provisional application.

The Examination Process

Once your non-provisional application is submitted, it enters the examination process. A patent examiner reviews the application, comparing the invention against prior art to determine its uniqueness. This phase can be lengthy, sometimes taking several years. The complexity of your invention, the field it’s in, and the workload of the patent office all contribute to this duration.

Moreover, the examiner’s approach and experience can play a role. Some examiners are more thorough or meticulous, which can either be a boon—ensuring your patent withstands future challenges—or a source of delay if they’re especially nitpicky.

During this period, you might encounter an office action, where the examiner poses questions or raises objections to your application. Responding timely to these office actions, ideally with the guidance of a patent attorney or a patent agent beforehand, is crucial to avoid delays.

Factors Influencing the Duration

Several factors can influence how long it takes to get a patent:

  1. Complexity of the Invention: Naturally, more complex inventions require a more detailed analysis, leading to extended examination periods. For instance, computer software or intricate business methods might undergo more scrutiny than a simple mechanical device.
  2. Quality of the Patent Application: A well-drafted application, complete with clear claims, detailed drawings, and a thorough written description, can speed up the process. Employing a reputable patent attorney can be beneficial here.
  3. The Backlog of the Patent Office: The USPTO, like many patent offices worldwide, often has a backlog of applications. The wait time before an examiner begins reviewing your application contributes significantly to the overall duration.
  4. Office Actions: If an application initially gets rejected or requires clarification, the subsequent back-and-forth can prolong the approval time.

Provisional Patent Application: A Temporary Shield

Before diving into the full-fledged patent application process, many inventors opt for a provisional patent application. This offers a 12-month window where inventors can claim “patent pending” status. What does this mean? Essentially, it allows inventors to safeguard their invention while not yet committing to the full patent process.

This interim period can be invaluable, giving them time to refine their invention, test the market, gather investor interest, or even see if any unforeseen challenges arise. Plus, it can serve as a placeholder, ensuring that while the invention is under “patent pending” status, no one else can claim the same innovation. However, it’s crucial to remember that during the 12-month period, one must file a non-provisional application to maintain the initial filing date.

Patent Types and Their Durations

Different patents have varied durations:

  • Utility Patents: Protect functional aspects of inventions and last for 20 years from the original filing date. This category includes most inventions, from machines to computer software.
  • Design Patents: Guard the unique appearance of products and have a 15-year term from the date of grant.
  • Plant Patents: These protect new plant varieties and last for 20 years from the filing date.

The Examination Process: A Deep Dive by the Patent Office

Once your non-provisional application is submitted, it doesn’t mean you’re immediately granted a patent. Instead, the patent office, be it the USPTO or any other national office, embarks on an extensive review. This is where patent examiners come into the picture. These are professionals skilled in various technological domains, and their job is to thoroughly scrutinize your application.

They compare the invention against prior art, which includes any existing patents, publications, or public disclosures, to establish its distinctiveness. But why can this phase stretch on for years? Several reasons contribute to this duration: the invention’s complexity, the technological sector it resides in, the clarity and quality of your application, and the patent office’s current workload and backlog. Inventors need to brace for this duration and be ready to respond to any queries or objections the office may raise.

Filing Date: Marking the Beginning

When you hear about the “filing date,” it’s easy to dismiss it as just another administrative detail. But in the world of patents, it’s much more than that. The day you submit your patent application, be it provisional or non-provisional, becomes its official filing date. But why is this date so pivotal? It acts as a marker, establishing the priority of your invention.

Timing can be everything. If two inventors come up with a similar innovation, the one with the earlier filing date usually has the upper hand. This priority becomes especially crucial when contesting the originality of your creation against other inventors or when defending your patent rights in potential legal disputes. In essence, this date can be the line between owning a groundbreaking innovation and just missing out.

Final Thoughts

After enduring the examination process and possibly multiple office actions, receiving the patent grant is a triumphant moment. But, it’s essential to note that there are maintenance fees to keep the patent active. Depending on your patent type and the duration since the grant, these fees can vary.

In conclusion, the time it takes to secure a patent hinges on numerous factors, ranging from the type of patent to the quality of the application and the intricacies of the invention. While it’s a demanding journey fraught with legal requirements and potential obstacles, the protection a patent offers makes the endeavor worthwhile. For those embarking on this path, persistence, a well-drafted application, and the guidance of experienced patent professionals can prove invaluable.
