Examples of successful US manufacturer IPRs
Below are examples of large and small manufacturers successfully using the inter partes review (IPR) to defend themselves from patent infringement lawsuits based around bad patents the US Patent and Trademark Office (USPTO) should have never issued.
Unlike a trial in federal court, which could have taken these manufacturing companies over five years and cost over $3 million to litigate, an IPR takes no more than 18 months and on average costs between $300,000 and $1 million.
In each short example below, the patents used to sue the manufacturing company were invalidated as a result of the IPR. This is essentially a legal finding that they should have never been granted by the USPTO. Though very few bad patents slip through the system, they can be used to do immense harm to manufacturers.
