Not quite a year ago, I posted an article about the term, “patent pending” and its sufficiency towards protecting your invention. Since that time, I’ve had a good number of people ask me just what the term means. I’ve also had people ask me, “so now that my patent is pending, I can sue people?” It seems the demand for these answers is high, so a refresher on “patent pending” seems appropriate.
Let’s start with the basics. What exactly does “patent pending” mean? The term “patent pending,” or something similar such as “patent applied for,” is used by a manufacturer or seller of an article to inform the public that an application for patent on that article is on file in the United States Patent and Trademark Office. Use of these terms should not be abused, for example by printing “patent pending” on a product for which no patent application has been filed. The law imposes a fine on those who use these terms falsely to deceive the public.
However, just because a searching party cannot locate a patent application on the invention through popular searches, such as Google Patents or the USPTO website, does not mean that no patent application is pending. Most patent applications filed on or after November 29, 2000, will be published 18 months after the filing date of the application, or any earlier filing date relied upon under Title 35, United States Code. Otherwise, all patent applications are maintained in the strictest confidence until the patent is issued or the application is published.
Once a patent application has been filed with the US Patent and Trademark Office, the disclosed invention may be considered “patent pending.” This holds true for both provisional and non-provisional patent applications. Provisional patent applications are not examined by the USPTO for patentability, but provide a disclosure of the invention with enough sufficiency to receive a filing date.
Non-provisional applications are examined by the USPTO, and may result in the issuance of a patent. In order to have any patent protection, an inventor is required to file a non-provisional application. To keep the filing date of a provisional patent application, an applicant is required to convert the provisional patent application into a non-provisional patent application within one year of filing the provisional.
So, can you sue if you believe someone is infringing on your patent pending invention? Not just yet. In short, the USPTO states, “These phrases have no legal effect, but only give information that an application for patent has been filed in the Patent and Trademark Office. The protection afforded by a patent does not start until the actual grant of the patent. False use of these phrases or their equivalent is prohibited.”
The term “patent pending” describes the period between the filing of a patent application with the USPTO and the final disposition on the application, which may include abandonment, rejection, or allowance of the application. Having a “patent pending” status does not afford an applicant any patent protection, it simply puts would-be infringers on notice that they may be subject to a lawsuit if the application issues into a U.S. patent.
Furthermore, 35 U.S.C. 287 provides the notice requirements for issued patents, stating, “In the event of failure so to mark, no damages shall be recovered by the patentee in any action for infringement, except on proof that the infringer was notified of the infringement and continued to infringe thereafter, in which event damages may be recovered only for infringement occurring after such notice.”
By providing notice to the public that your invention is in the process of potentially receiving patent protection, you are providing notice that continued potentially infringing conduct related to the applied-for invention may result in patent infringement. Although patent protection may not begin until the date a patent is issued, including a notice that such date is pending may help allow an inventor claim satisfaction of the notice requirement being met close to the actual date issue date of the patent, so long as the inventor promptly complies with the patent marking requirements of 35 U.S.C. 287.
However, the courts have routinely decided that “patent pending” alone is insufficient to support a finding of willful infringement. The Federal Circuit has stated, “A patent pending notice gives one no knowledge whatsoever. It is not even a guarantee that an application has been filed. Filing an application is no guarantee any patent will issue and a very substantial percentage of applications never result in patents. What the scope of claims in patents that do issue will be is something totally unforeseeable.” Conopco, Inc. v. May Dep’t Stores Co., 46 F.3d 1556, 1562.
