Patent prosecution is a notoriously lengthy process. It often takes more than a year for businesses to successfully prosecute the patent, even with experienced legal representation.
The United States Patent and Trademark Office (USPTO) must assess the patent application on its own merits. Professionals working for the USPTO must also conduct an exhaustive review to ensure that granting the patent does not infringe on the rights of anyone who already holds a similar or related patent. Once the USPTO grants a patent, the applicant theoretically has sole control over and use of the patented process or concept.
Occasionally, patents end up under scrutiny and at risk of early termination due to a reexamination. Who can ask the USPTO to re-examine a patent?
Anyone can question patent validity
A patent reexamination can generate substantial legal fees and disrupt the monetization or licensing of a patented idea. Re-examinations sometimes draw media attention, especially when there is controversy regarding a specific patent. If the USPTO determines that granting the initial patent was a mistake, the consequences of that reexamination can be devastating for patent holders.
Any party with credible information that raises questions about an existing patent’s validity can potentially initiate the ex-parte reexamination process. Frequently, the party requesting the examination is not a USPTO worker or someone associated with the company that holds the patent. They may be a competitor or a business leader in an adjacent field.
Being ready to defend an existing patent is as important as preparing before prosecuting a patent initially. Understanding the basics of the patent reexamination process can help patent holders respond effectively when outside parties raise questions about the validity of their intellectual property protections.
