How Long Do Patent Infringement Cases Take?

When a party files a patent infringement case, they are generally concerned about establishing liability. This may require preserving evidence of infringement. Electronic and tangible evidence may decay over time. The earlier the suit is filed, the sooner the witness memories will be fresh. The longer the case takes, the more complex it will be and the more complicated the arguments will be. In a typical case, the process will take a year or so.




A court will often first issue a Markman opinion to determine whether the patent holder infringes upon another party's patent. If the latter is found liable, the court will issue a permanent injunction that prevents them from producing the infringing products. This stage is also a critical one. During this phase, the court will also address any lingering disputes.


The next step in the process is a trial. If a patent holder wins, the lawsuit will involve the courts weighing the potential exposure against the chance of success. In a typical case, a judge will decide whether a patent holder will prevail after proving that the accused product is infringed. An infringement case will typically take a year or more, but can take up to three years.


The trial itself can take many months. A case will be settled after the Markman opinion is written. A court's decision on whether a patent is valid or infringed will determine whether a settlement will be reached. A patent infringement case can also prevent a company from selling its products in the market. A judge can also order the defendant to pay its customers in damages. This can be very expensive.


During a trial, the parties may agree to an out-of-court settlement. Depending on the outcome of the trial, the defendant may settle and seek immediate relief from the courts. Usually, the case will be resolved through a zex parte interim injunction. The parties involved in a patent infringement lawsuit often opt for mediation. A zex parte injunction will be issued before the trial. The judges have the discretion to issue a Markman opinion. If the two sides fail to reach an agreement, the court will then issue a summary judgment.


In patent infringement cases, the defendant must pay reasonable royalties, which may include actual damages. Depending on the circumstances, royalties can range from a few thousand to tens of thousands of dollars. If the parties cannot reach a settlement, they will typically file a motion for summary judgment. A ruling will likely be made within a year. Infringing a patent case requires time and effort.


Patent owners are often able to stop the infringement of their patents. In such cases, the court will issue a permanent injunction, which prevents the defendant from manufacturing the infringing product. In such cases, the patent owner can also seek damages if the infringing product is made by competitors. Once the defendants have been held liable, the parties can move for summary judgment.


The cost of a patent infringement case is based on several factors. A successful lawsuit will typically require the infringer to pay damages. A fair and reasonable royalty is a proportion of the profits that an infringer makes. This can range from a few thousand to millions of dollars. The amount of damages awarded in a patent infringement case will depend on the product and the length of the patent.




While most patent infringement cases are resolved in the courts through settlement, a patent holder must file a lawsuit within six years of the alleged infringement. This period can be extended only in extreme circumstances, such as fraud or concealment. In such situations, the patent holder must file a motion for summary judgment if he wants to get a fair outcome. However, a defendant must show that he or she has not made any attempt to avoid liability in the first place.


Patent infringement cases take a year or two. During this time, the parties can file an appeal against the judgment. This is a relatively simple process, and a jury decision is usually rendered within about a year. Depending on the court's rules, the court can order the parties to exchange claim construction contentions at the outset or put them off until the end of discovery. It is during this phase that most of the action in a patent infringement case occurs. During this phase, the parties exchange documents, answer interrogatories and conduct depositions.
