The actual amount of time it will take for your patent application to be examined, and if found allowable, to issue into a patent will vary. If one art unit has more patent applications in the queue than another art unit, then patent applications assigned to the art unit with relatively more patent application will wait longer for examination and ultimate issuance.
If you decide to file a provisional patent application, the patent office will not put your provisional patent application in a queue to be examined. Instead, a non-provisional patent application must be filed within one year of the filing date of the provisional application, in order to claim the benefit of the provisional application filing date. In the case that you file a provisional and then file a provisional on the one year anniversary date of the filing of the provisional, one additional year will be added to the times listed above.
Patent attorneys say you should only talk about your work after it has a patent pending. Many investors, licensees, and potential buyers appreciate the credibility that comes with a patent pending designation. It can help you secure financing and market your product.
When you have a patent pending, you don't have to ask investors or manufacturers to sign a nondisclosure agreement NDA. Once your patent is pending, you can put a notice on your product and any collateral you use to promote it. It's legal to use patent pending in these cases:. There aren't set standards on how to mark your product with a patent pending status.
You can use any of these or similar terms:. The notice you use must be accurate. Don't use "U. Place the notice in a visible spot on your product, website, and other materials. It's illegal to use the patent pending label on your product or promotional assets if you haven't applied for a patent or you've received your patent. The label only applies for the time when you're waiting for the USPTO to approve or deny your application. After the USPTO gives the patent or the inventor abandons the application, the inventor can no longer use the patent pending notice without breaking the law.
Once inventors receive a patent, they replace "patent pending" with the patent number. It can look like this: Pat. Filing an application in the U. An invention must pass the prior art search and be deemed patentable.
There are a few countries that gives a patent to anyone who files an application without examining the application. If you get a patent, it will last for 20 years from the date you submitted your full application. The filing date of a PPA does not count toward the 20 years. Many patents are pending for several years.
Expect a shorter wait for design patents. Whatever invention you describe in your patent application is what gets patented.
If you change your invention after applying, the new version of your product will not be included in the patent. This is an important consideration for anyone who continues tweaking his or her product after applying for a patent.
The USPTO gives prioritized examinations, also known as Track One, for plant and utility patent applications to a specific number of applications each year. Read more. Excellent article John. I repeat a request from before: Has a patentee ever gotten the post-publication, pre-grant reasonable royalties that publication is suppose to provide?
I have never seen a case where they have, but maybe I missed one. Thanks for the informative graph, though a couple of clarifications and corrections are in order here.
It is unclear whether the graph is for the publication date of patents or patent applications. The following corrections should also be noted:.
Those who assume there is such post-AIA grace period do so at their peril. Those studying PTO statistics would find that there are about twice as many continuations filed compared to divisionals and four times as many compared to continuations in part. I dispute the logic of that statement. Since most of the early publication applications are continuations and divisionals, their specification will usually be identical in substance to the original application — which in most cases would have been published 18 months after filing.
Therefore, they are merely a repeat publication and not first publication. I think that there are several more pernicious ramifications of the publication change to patent law than the mere phantom or not timing aspect. Long Answer: There are no guarantees of success in obtaining patent protection with United States Patent and Trademark Office USPTO , the European Patent Office, or any other patent office around the world, regardless of the invention for which patent protection is being sought.
In the United States, the average time to receive a decision about a patent application varies significantly depending on several factors, including the type of patent being sought, the breadth of protection being sought, the quality of the patent application, and the type of technology.
The most common types of patents inventors usually seek are design patents and utility patents. A design patent protects the appearance of an article. This may include its shape or surface ornamentation or other aspects of how it looks. A utility patent protects the function of an article. This may include how it is used or how it works. Generally, design patent applications experience shorter wait times than utility patent applications.
It is not uncommon for a design patent application that is judged worthy of patent protection to receive a notice of allowance from the USPTO in one to two years from the date the application is filed. However, notices of allowance for utility patent applications that are approved can be mailed anywhere from one to five or more years from the date the application is filed.
Patent applications that seek broad coverage generally define invented concepts that are closer, in terms of scope of coverage, to known subject matter i.
