Frequently asked questions.
What is Patent Litigation?
Patent litigation is a process through which the patent holder sues another party for making unlawful and unauthorised claims on their patented invention. Generally, a patent gives you exclusive rights to produce, sell, licence, and use your invention. Therefore, as a patent holder, you can take legal action against another party that infringes on these rights. This could include seeking an injunction, sending a cease or desist letter, claiming monetary damages, or negotiating a licensing agreement. Ultimately, the goal is to stop the infringement or seek compensation for damages.
Taking a patent infringement case to court is a serious decision you shouldn’t take lightly. While some cases could be quickly resolved through negotiations, others might require you to pursue litigation. Such cases include:
Unauthorised use: This is a situation in which a third party uses your patented technology or product without your permission.
Unauthorised sale occurs when competitors or other businesses are selling your patented product without proper consent.
Unauthorised production is when a third party engages in small or large-scale production of your patented product without a licence or agreement.
The Patent Litigation Process
Defending a patent in court becomes less complex when you understand how to go about it. Here are the legal steps in a patent litigation process:
Pre-Litigation Steps
Before filing a lawsuit, patent holders usually explore several pre-litigation steps to resolve the issue without involving the court. These steps include:
Sending a cease and desist letter: This letter lets you inform the other party about your patent rights, explain how those rights have been infringed, and demand that the infringement stop.
Negotiation: After receiving the cease and desist letter, the other party may choose to negotiate a licensing deal with the patent holder.
Potential settlements: The cease and desist letter could also lead to a settlement agreement between the parties, which could involve financial or licensing agreements.
Filing a Lawsuit
If these pre-litigation attempts fail, the next step is to file a patent infringement lawsuit. This process typically begins with submitting a complaint to the appropriate court. This complaint should contain the details of the alleged infringement, identify the patent in question, and specify the legal basis for the infringement claims. Once the complaint is filed, the next step is to formally notify the defendant of the lawsuit through a service of process. This involves delivering a copy of the complaint and a summons, which compels the defendant to respond and appear in court.
After receiving a copy, the defendant must respond to the complaint by denying the infringement, challenging the patent's validity, or raising other defences. Furthermore, the lawsuit must be filed in a court with the jurisdiction to hear the case. In the UK, patent litigation falls under the jurisdiction of the Patent Courts, a specialised division of the High Court.
Discovery Phase
This is the phase where both parties gather evidence to build their case. It includes:
Document production: Both parties exchange relevant documents such as patent records, product designs, and correspondence.
Expert testimony: Experts are often brought in to explain any technicalities involved in the case.
Deposition: This involves questioning witnesses and experts from both sides under oath.
Interrogatories: Written questions are exchanged between parties and they are required to respond under oath.
Trial and Judgment
If the case isn’t settled during the discovery phase, it proceeds to trial. The trial process typically begins with both parties presenting their opening statements to the judge. This usually contains a brief overview of their case. After this, the plaintiff presents evidence of the alleged infringement, while the defendant also brings their defence.
In most cases, expert witnesses are brought in to give their opinions on the patent's validity and the alleged infringement. Once this is over, both parties give their closing arguments by highlighting the key points of their case. In the end, the judge issues a ruling based on the evidence presented by the parties.
Post-Trial Considerations
Once a judgement is made, there are several important factors to consider moving forward.
Enforcement of the court’s decision: If you win the case, the next step is to seek a way to enforce the court’s decision. This could be by collecting monetary damages or securing an injunction to stop the infringement.
Appeals: If you’re dissatisfied with the court’s decision, you can appeal to a higher court. This could lead to a case review and potentially a new ruling.
Settlement: Even after the trial, both parties can decide to reach a settlement to prevent the case from being prolonged through further appeals.
Key Legal Concepts in Patent Litigation
One vital way to navigate a patent litigation process is to understand its key legal concepts. These concepts cover aspects such as the types of infringement, validity, enforcement, damages, and remedies.
Infringement Types
A patent infringement lawsuit is usually based on either of these two claims:
Direct infringement is a straightforward type of infringement that occurs when a party uses, manufactures, or sells a patented invention or service without the patent holder’s permission.
Indirect infringement occurs when a party doesn’t directly commit a patent infringement but induces or aids another person to do so.
Contributory infringement is a subset of indirect infringement in which a party aids another party in infringing a patent by supplying them with a component of the patented invention.
Validity and Enforcement
Another key concept to consider is validity and enforcement. Challenging the validity of a patent is one of the common defences of defendants during litigation. This could be due to a lack of novelty, non-obviousness, or issues with patent specification. Furthermore, a court could deem your patent invalid if it has expired or doesn’t meet statutory requirements.
Validity and enforcement are like two sides of a coin because you can’t enforce a patent without proving its validity. You also need to prove that the defendant’s actions constituted an infringement.
Damages and Remedies
The damages and remedies available to a patent holder include:
Compensatory Damages: These are awarded to replace what the patent holder has lost. They can include lost profits or reasonable royalties based on what the infringer would have paid if they licensed the patent.
Injunctions: These remedies are granted to stop the infringing activity. Injunctions can be preliminary (issued during litigation) or permanent (after the case is concluded).
Punitive Damages: In cases where the defendant knowingly infringes a patent, the court may award triple what the compensatory damages would have been.
Risks and Benefits of Patent Litigation
Although patent litigation is a crucial means of protecting intellectual property, it poses some significant risks. Therefore, weighing the benefits and risks before deciding that litigation is the way you want to go is essential.
Benefits
Deters future infringement: Taking legal action sends a clear message to the public that you’re prepared to enforce your rights. This could help deter others from infringing on your patent in the future.
Secures market share: Patent litigation is a good way to protect your market impact. It prevents competitors from producing or selling your patent without permission, allowing you, the patent holder, to capitalise on your invention and maintain its exclusivity fully.
Risks
Costs of Litigation: One of the major concerns of litigation is its financial impact. The process is often expensive as it involves legal fees, court costs, and the costs of bringing in expert witnesses. Most litigation processes also tend to be prolonged, especially if the case involves complex technical issues. This could lead to even more substantial costs that make the financial strain outweigh the potential benefits.
Risk of Invalidity: Another major concern is that the defendant may dispute the patent's validity. If the court eventually determines the patent invalid, the holder might lose their exclusive rights to the invention. This is usually more devastating in cases where the patent is central to a company’s market strategy.
Alternatives to Patent Litigation
After considering the benefits and risks, you might find that litigation could cause more harm than good. In that situation, exploring alternative methods for resolving intellectual property disputes can be a better option. These alternatives are typically faster, less costly, and can help you address the infringement while preserving important business relationships.
Mediation and Arbitration
Mediation and arbitration are two alternative methods of resolving intellectual property disputes. Mediation involves a neutral third party who helps the disputing parties reach a mutually beneficial agreement, while arbitration involves an arbitrator who listens to both sides and makes a binding decision. Both methods are fast, flexible, and private, making them the best option for business relationships.
Licensing Agreements
This is a method through which the patent holder permits the infringer to use their invention in exchange for royalties and compensation. It allows for a win-win situation where both parties get significant benefits from the agreement.
FAQs
How long does patent litigation typically take?
