Patent litigation involves one party initiating legal action against another for allegedly unauthorized use of their patented invention. The process begins with a patent, which the United States Patent and Trademark Office (USPTO) issues. Patent holders are entitled to prevent others from manufacturing, using, selling, or importing their patented product, process, or service. Patents generally remain valid for 20 years from the filing date, although some may only last for 15 years. Importantly, the federal government does not enforce patent rights; enforcement is the responsibility of the patent holder. If a patent is believed to be infringed, the holder may file a civil lawsuit in a U.S. district court to resolve the matter.
There are three primary types of patents: utility, design, and plant patents. Utility patents, which comprise about 90% of all issued patents, cover inventions of new and useful processes, machines, manufactures, or compositions of matter, or improvements thereof, providing protection for up to 20 years from the filing date. Design patents cover new, original, and ornamental designs applied to articles of manufacture and last for 15 years. Plant patents protect new or uniquely discovered asexually reproducing plants for 20 years.
When it comes to patent infringement complaints, they generally fall into two distinct categories: direct infringement and indirect infringement. Understanding these can help in navigating the complexities of patent law.
Direct patent infringement occurs when an entity or individual engages in the unauthorized manufacturing, usage, sale, offer to sell, or importation of a patented invention, method, or service. This form of infringement is straightforward: the infringer directly engages in activities that violate the patent holder’s exclusive rights.
Indirect patent infringement involves cases where the defendant may not have directly infringed the patent themselves but has contributed to or induced another party to commit an infringement. This category is further divided into:
By distinguishing between these types of infringements, stakeholders can better understand their legal positions and potential defenses in patent litigation.
Before a patent trial begins, the judge conducts a Markman hearing, an essential pre-trial stage where the meanings of specific terms within the patent are determined. This hearing involves the examination of intrinsic evidence, including patent claims and prosecution history, as well as extrinsic evidence like legal dictionaries and expert testimony. The outcome of the Markman hearing is crucial as it can significantly influence the verdict, especially if the case hinges on the interpretation of a particular patent claim.
A patent infringement trial typically proceeds before a jury that assesses factual issues and determines damages if the defendant is found to have infringed upon the patent. Given that most juries are not familiar with technical details of patents, plaintiff attorneys begin by explaining how the patent works. This stage often includes testimonies from the patent owner, inventor, and key clients who may have lost business due to the infringement.
Plaintiff attorneys also present expert testimony regarding the alleged infringement and the suggested amount of damages. Conversely, the defense will cross-examine these witnesses and introduce their own to contest the patent's validity and argue against the claims made by the plaintiff.
If infringement is proven, the patent owner can seek several remedies:
Following the trial, the losing party may file post-trial motions to overturn the verdict due to various issues, such as errors during the trial or attorney misconduct. Appeals are typically directed to the Federal Circuit, where the case must be docketed within ten working days. Decisions at this level generally take about a year.
