What is the forum for the conduct of patent litigation?
In the United States, patent suits are often initiated in a federal district court. There are 94 federal district courts in the United States. Each patent suit is assigned to a single judge and, except in abbreviated new drug application (“ANDA”) litigation (a proceeding specific to pharmaceutical patents), a party to the litigation may request a trial by jury. While some jurisdictions have specified judges to handle patent suits, most judges are generalists and handle any cause of action that can be filed in a federal court, including civil and criminal filings. In addition to the federal district courts, there are three specialty forums for certain types of patent disputes. The Court of Federal Claims (“CFC”) hears patent infringement actions against the federal government. The International Trade Commission (“ITC”) is an administrative agency through which a patent owner may request an exclusion order blocking imports of infringing products. The Patent Trial and Appeal Board (“PTAB”), which is part of the United States Patent and Trademark Office (“USPTO”), hears post-grant validity challenges like inter partes review (“IPR”). Unlike the federal district courts, CFC, and ITC, the PTAB does not decide issues of infringement.
What is the typical timeline and form of first instance patent litigation proceedings?
For a patent litigation in a federal district court, the time from filing a complaint to a trial decision varies across the 94 district courts. Typically, the time to a decision by trial is 15-36 months, including in the most active courts, such as the Western District of Texas, District of Delaware, Eastern District of Texas, Central District of California, and Northern District of California. In some courts, such as the Eastern District of Virginia, the time to a decision by trial is shorter and can be reached in 14-18 months. In the United States, the trial decision usually includes a single verdict covering infringement, validity, and damages. Many district courts have patent-specific “local rules,” which set deadlines before a trial for each side to disclose their infringement and invalidity contentions, and their positions on claim construction. Claim construction is usually decided through a specific briefing and hearing process (known as a “Markman hearing”) during the litigation. However, judges are afforded deference in managing their own dockets, and so the process for claim construction in each case may vary. Proceedings in the ITC are fast-paced and typically take 12-15 months to reach an initial determination. No damages are available at the ITC. Instead, the main remedy is an exclusion of the importation of the infringing goods. PTAB proceedings are limited to rulings on validity and must be completed within 12 months of the date the PTAB institutes a proceeding. The institution of a PTAB proceeding is based on a number of factors and institution may be denied if, for example, there are overlapping issues in a parallel or prior proceeding.
Litigants should keep in mind that the COVID-19 pandemic has impacted trial schedules in most district court actions. Stipulating to a trial before a judge only, also known as a bench trial, can help prevent delays in the case timetable.
Can interim and final decisions in patent cases be appealed?
Appeals based on substantive patent law from the district courts, CFC, ITC, and PTAB are all heard exclusively by the United States Court of Appeals for the Federal Circuit (“CAFC”), which is located in Washington, D.C. Typically, a decision must be part of final judgment in order to be appealable. If a party does not preserve their rights on an issue in the court of first instance, an appeal of that issue may be waived. While a final judgment is usually required for an appeal to be ripe, exceptions are made by statute for particular issues, such as decisions on injunctive relief. With respect to the PTAB, it is notable that a decision on whether to institute or deny a petition for IPR is not appealable to the CAFC.
Which acts constitute direct patent infringement?
Direct infringement occurs when a single actor performs all of the actions needed to establish infringement of a patent claim. Those acts can include making, using, offering for sale, or selling the invention protected by the patent in the United States, or importing the invention protected by the patent into the United States. Direct infringement may also be committed by more than one actor or party, but only when that party directs or controls another’s performance, such as when there is a principal-agent relationship, in a contractual arrangement, or in a joint enterprise.
Do the concepts of indirect patent infringement or contributory infringement exist? If, so what are the elements of such forms of infringement?
Yes, indirect infringement may take the form of either inducement to infringe or contributory infringement. A party may be liable for inducing infringement if they knowingly induce another to directly infringe a patent. For example, providing instructions on how to use a product which, when performed, will infringe the patent can be an element of inducement. A party may be liable for contributory infringement if they provide a component or material especially made or adapted to be used in an infringing manner. For example, if a party provides a part that is not infringing by itself but is especially made to be combined with a different part to form an infringing device, that can be an element of contributory infringement. It is important to note that, for both inducement and contributory infringement, an underlying instance of direct infringement by someone is a prerequisite.
How is the scope of protection of patent claims construed?
Literal infringement occurs when the accused product or process falls within the scope of a properly construed claim. Claim construction is determined by the court, usually through a briefing schedule and specific hearing (known as a “Markman hearing”) before trial. Where there is no literal infringement, infringement can still be found under the doctrine of equivalents. According to this doctrine, infringement occurs if a product or process does not fall within the literal scope of the properly construed claim but is the substantial equivalent of the patented invention. To determine equivalence, a judge or jury analyses whether the differences between the two are insubstantial to one of ordinary skill in the art. Prior art and prosecution history estoppel can limit or block the application of the doctrine of equivalents.
What are the key defences to patent infringement?
The primary defenses to patent infringement claims are noninfringement and invalidity. The burden rests on the patent owner to prove infringement, while the burden rests on the accused infringer to prove invalidity. Infringement and validity are usually contested in most actions. Examples of other defenses include laches (based on delay bringing suit), equitable estoppel (based on misleading conduct by the patent owner toward the defendant), inequitable conduct (based on misleading conduct by the patent owner toward the USPTO), and exhaustion (based on an “upstream” license or sale by the patent owner).
What are the key grounds of patent invalidity?
Issued patents are presumed valid by statute. In order to show a patent is invalid, the accused infringer needs to prove by clear and convincing evidence that the patent fails one of the requirements for patentability found in 35 U.S.C. §§ 101, 102, 103, and 112. Section 101 deals with subject matter eligibility. A patent must claim a new and useful process, machine, manufacture, or composition of matter, or an improvement thereof, and may not be directed solely to an abstract idea, natural phenomenon, or law of nature. Section 102 addresses whether the claimed invention is novel, or more specifically whether all the claimed elements are disclosed in a single piece of prior art. Section 103 deals with obviousness. If no one piece of prior art discloses the claim elements, the claim may still be invalid if it would have been obvious before the effective filing date in light of the teachings of a single reference or a combination of references. And finally, Section 112 deals with the patent’s disclosure and requires that the elements claimed by the patent must be enabled and sufficiently described in the patent’s specification. Section 112 also requires the disclosure of the best mode contemplated by the inventor. While the Patent Office may reject an application for failing to meet this requirement, under the America Invents Act (“AIA”), the failure to disclose the best mode cannot be used to invalidate a claim of a patent in actions filed on or after September 16, 2011.
How is prior art considered in the context of an invalidity action?
The scope and content of prior art is defined in 35 U.S.C. § 102. This section was amended by the AIA, and the new definition of prior art applies to applications containing at least one claim with an effective filing date after March 15, 2013. For applications containing claims only with effective filing dates before March 16, 2013, the old law applies. The principal difference is that the AIA moved the United States from a first-to-invent system to a first-inventor-to-file system. It also removed geographic and language restrictions from the previous definition of prior art. Disclosures outside of the United States before the effective filing date may now serve as invalidating prior art. There are exceptions, however, such as the one-year grace period for an inventor’s own work, which remains an exception under the AIA. This is in contrast to the absolute novelty standard mandated by the patent laws of other countries.
Can a patentee seek to amend a patent that is in the midst of patent litigation?
A patent owner cannot amend a patent claim through a litigation proceeding in a district court, with the exception of limited corrections for obvious errors. Nevertheless, a patent challenged at the PTAB may be amended during the PTAB proceeding. However, any amendments must be made by motion, which are not frequently granted by the Board. Also, because PTAB proceedings are adversarial, proposed amendments may be challenged by the party that commenced the proceeding. Claim amendments at the PTAB may only narrow claims and may not broaden claims in any respect. When amendments are permitted, it is important to note that the patent owner may potentially forfeit past damages that may otherwise have been available for the original claims.
Is some form of patent term extension available?
Patent term extensions may be granted because of delays in prosecution which are the fault of the USPTO. These extensions will be granted at issuance and are not typically subject to challenge without a civil action. Patent owners can also apply for term extensions due to delays by other government agencies. A typical example is a patent for a drug which needs FDA approval to be sold. These extensions are governed by 35 U.S.C. § 156.
How are technical matters considered in patent litigation proceedings?
In addition to documents and factual testimony, which are collected during fact discovery, patent litigation in the U.S. often involves expert witnesses to address issues such as infringement and validity. Competing expert witnesses will usually be retained by the patent owner and accused infringer. During expert discovery, these witnesses are required to submit a report describing their opinions and the facts which support them, may optionally submit a rebuttal report addressing the opinions of the opposing side’s experts, and must be offered for deposition to the opposing side. While expert witnesses are retained by the parties and tend to advance the parties’ respective positions, ultimately their duty is to provide opinion testimony that is based on sufficient facts or data and the product of reliable principles and methods.
Is some form of discovery/disclosure and/or court-mandated evidence seizure/protection (e.g. saisie-contrefaçon) available, either before the commencement of or during patent litigation proceedings?
The United States does not have a saisie-contrefaçon procedure. Nor do federal district courts allow for compulsory pre-complaint discovery. Patent owners have a duty to make a reasonable investigation on their own into the facts underlying their claims before bringing a patent suit. After a complaint is filed, fact discovery in the United States is broad and more intensive than in other countries. Parties may serve on each other requests for documents, requests for admission, requests to inspect property or other items, interrogatories, and requests for deposition. Parties may also serve subpoenas on third parties, requiring the production of documents, inspection of premises, or witness testimony. For a litigation or proceeding in a foreign or international tribunal, 28 U.S.C. § 1782 permits a U.S. district court to order a United States resident to give testimony or produce documents for use in that litigation or proceeding. The district court will consider factors such as the nature of the proceedings and laws of the foreign jurisdiction before deciding whether to issue the order.
Are there procedures available which would assist a patentee to determine infringement of a process patent?
As the scope of fact discovery in the United States is broad, the use of a patented process can be established through discovery tools, such as requests for admissions, requests for production of documents, depositions and live witness testimony, inspection of premises or things, and interrogatory responses. Expert testimony may also be helpful where practice of a patented process can be shown through inspection of the accused products and analysis of the accused infringer’s documents.
Are there established mechanisms to protect confidential information required to be disclosed/exchanged in the course of patent litigation (e.g. confidentiality clubs)?
Confidential documents are typically produced pursuant to a “protective order” entered by the court. The protective order regulates who may access such documents and under what conditions. Most courts have a standard protective order, but these orders can be modified through negotiation between the parties and to address the particular needs of a case. Typically, the party seeking to protect their material must ensure that it is appropriately marked, and the party receiving the material must ensure access is limited as described in the protective order. Different levels of protection are usually available for different levels of confidential material. In addition, aligned parties (e.g., multiple co-defendants) may enter common interest agreements, which can provide protections for confidential and/or privileged information shared with each other. Confidential documents are also typically redacted or sealed from the public when relied upon for public filings like motions or briefs. But there is a competing public interest in knowing the justification for judicial decisions and sometimes previously sealed material will be disclosed at trial or in a final judgment.
Is there a system of post-grant opposition proceedings? If so, how does this system interact with the patent litigation system?
There are two main types of post-grant challenges. First, parties may seek review in adversarial proceedings at the PTAB. These proceedings include post-grant review (“PGR”), IPR, and derivations. Second, parties may file ex parte re-examination requests, which are not adversarial and essentially place the challenged patent back in examination at the USPTO. Accused infringers often try to stay litigation proceedings pending the outcome of a post-grant validity challenge. Courts are reluctant to grant stays unless and until the PTAB or reexamination branch of the USPTO decides to institute a review proceeding. Courts also look at other factors such as how soon the litigation will reach a trial, potential prejudice to the patent owner, and the accused infringer’s diligence in seeking the post-grant challenge.
To what extent are decisions from other fora/jurisdictions relevant or influential, and if so, are there any particularly influential fora/jurisdictions?
The United States follows the common law tradition of applying precedent. This means that the federal district courts, CFC, and ITC are bound by decisions of appellate courts, primarily the CAFC. They also generally follow prior decisions within their own jurisdiction. Decisions from other domestic jurisdictions (e.g., federal courts in other states) have persuasive authority but are not mandatory precedent. Decisions from outside the United States can also be noted, but tend to not be influential. Exceptions include doctrines such as collateral estoppel and res judicata. These doctrines may bind particular parties to findings of law or fact in one jurisdiction to the same findings if the parties try to re-litigate the issues in the same or another jurisdiction. The interplay between litigation and PTAB rulings on validity is also important. In general, courts are not required to adhere to PTAB rulings that a patent is invalid unless and until the PTAB ruling is final and all appeal rights have been exhausted.
How does a court determine whether it has jurisdiction to hear a patent action?
Jurisdiction for patent suits is established under 28 U.S.C. § 1338. Under this statute, a patent owner may file suit in any federal district court where the defendant is subject to personal jurisdiction and venue is proper. In 2017, the principles for patent venue were significantly curtailed by the Supreme Court’s decision in TC Heartland v. Kraft Foods, 137 S. Ct. 1514 (2017). Under that decision, patent venue is only proper in judicial districts where the defendant is incorporated, or has some physical, established business presence and has committed the alleged infringement. However, for foreign defendants having no place of business in the U.S., venue is generally appropriate wherever the defendants are subject to personal jurisdiction. While courts are sometimes willing to transfer cases from one judicial district to another, based on convenience and/or other factors, anti-suit injunctions are exceptionally rare and very difficult to obtain.
What are the options for alternative dispute resolution (ADR) in patent cases? Are they commonly used? Are there any mandatory ADR provisions in patent cases?
Many courts require parties to engage in non-binding mediation at least once before a patent case goes to trial. Binding arbitration is an alternative to mediation, and is utilized in situations where, for example, the parties’ contracts require arbitration as a mechanism to resolve disputes.
What are the key procedural steps that must be satisfied before a patent action can be commenced? Are there any limitation periods for commencing an action?
Plaintiffs must perform a reasonable and good-faith pre-suit investigation into the facts and law underlying their claims, the standards for which are set by the Federal Rules of Civil Procedure, most specifically Rule 11. Failure to do so may result in sanctions. Plaintiffs also must file their suit in a court that has subject matter jurisdiction, has personal jurisdiction over the defendant, and has proper venue. There is no formal statute of limitations for patent suits. Nevertheless, under 35 U.S.C. § 286 patent owners are unable to recover damages based on infringement occurring more than six years before they file suit. There are also equitable defenses which may bar a party from bringing suit, like estoppel.
Which parties have standing to bring a patent infringement action? Under which circumstances will a patent licensee have standing to bring an action?
Two categories of rights holders may file a patent suit: the patent owner or an exclusive licensee with all substantial rights under the patent. A patent owner is an entity owning all rights and title in a patent. An exclusive licensee is generally an entity that, while not receiving legal ownership of a patent, receives all substantial rights (e.g., the rights to enforce and collect damages). By contrast, a bare licensee (i.e., an entity merely holding the right to practice a patent) has no standing to bring a lawsuit to enforce a patent. In addition, a patent owner may restrict the rights of an exclusive licensee, precluding its ability to sue independently or requiring the joinder of the patent owner to the action.
Who has standing to bring an invalidity action against a patent? Is any particular connection to the patentee or patent required?
To initiate a patent lawsuit in a federal district court on the basis of invalidity, the plaintiff needs to demonstrate that it faces a definite and concrete allegation of infringement by the patent owner. Without this, the court may dismiss the case for lack of declaratory judgment jurisdiction and lack of subject matter jurisdiction. Any entity (other than the patent owner) may initiate a PGR, IPR, or derivation proceeding at the USPTO. An IPR petition must be filed after nine months of the challenge patent’s grant date, and a PGR petition must be filed within that nine-month period. An ex parte re-examination proceeding may be filed any time by any entity, including the patent owner.
Are interim injunctions available in patent litigation proceedings?
Federal district courts can grant preliminary injunctions, but such injunctions are regarded as an extraordinary remedy. In order to obtain a preliminary injunction, a patent owner must demonstrate a substantial likelihood of success on the merits, the prospect of irreparable harm absent an injunction, that the balance of harms from an injunction supports granting the injunction, monetary damages would be inadequate, and the public interest favors the injunction. Preliminary injunctions are thus difficult to obtain and are generally only granted in suits involving direct competitors. Ex parte preliminary injunctions are even more rare and would arise if the accused infringer failed to make an appearance or defend the proceeding. When a court issues a preliminary injunction, it requires the patent owner (unless indigent) to post a bond covering the economic harm that would befall the accused infringer if the injunction is later found to be erroneous.
What final remedies, both monetary and non-monetary, are available for patent infringement? Of these, which are most commonly sought and which are typically ordered?
A prevailing patent owner is entitled to monetary damages and may, if appropriate, also obtain a permanent injunction against future infringement. Where the patentee practices their patent, they may seek monetary damages in the form of lost profits or a reasonable royalty. If the patentee does not practice the patent, only a reasonable royalty may be available. Regardless of which form of monetary damages is recovered, the patentee may also recover prejudgment interest. In a case between competitors, the patentee will usually seek the larger of either lost profits or a reasonable royalty. The patentee may also seek a permanent injunction. Where the patentee is a non-practicing entity (“NPE”), a reasonable royalty is usually the only available recovery, and an injunction is usually unavailable.
On what basis are damages for patent infringement calculated? Is it possible to obtain additional or exemplary damages?
There are two main forms of compensatory damages: a reasonable royalty and lost profits. A reasonable royalty may be based on a variety of rationales, as long as they are economically sound. For example, a reasonable royalty may be based on existing or comparable licenses, profit or revenue increases for the infringer arising from the infringement, cost savings achieved by the infringer through the infringement, the cost for the infringer to implement a non-infringing alternative, or other economic frameworks. Lost profits are based on the proven profits that the patent owner lost due to the infringement by the defendant. In addition, as a form of punitive damages, enhanced damages are available if the infringer engaged in egregiously infringing behaviour. This requires that the infringer knew of the patent, knew of the infringement, and affirmatively decided to proceed with the infringing conduct. If established, enhanced damages may result in the compensatory damages being increased by as much as three times. Also, while attorneys’ fees are usually not recoverable, they may be available for the prevailing party (either the patent owner or accused infringer) if the other side’s conduct during the litigation is egregious.
How readily are final injunctions granted in patent litigation proceedings?
Before the 2006 Supreme Court decision in eBay Inc. v. MercExchange, LLC, 547 U.S. 388 (2006), final injunctions were regularly granted in the United States upon a judgment of infringement and validity. That decision, however, tightened the standard. Courts now consider the following factors in deciding whether to issue a permanent injunction: (1) the patentee’s irreparable injury; (2) remedies at law being inadequate to compensate for the injury; (3) the balance of hardships favouring an injunction; and (4) the public interest not being disserved by the injunction. Under this test, direct competitors in a patent case are sometimes able to obtain a preliminary injunction. NPEs, on the other hand, rarely are able to do so. For NPEs, since monetary damages is usually adequate to compensate for the infringement, an injunction is unwarranted.
Are there provisions for obtaining declaratory relief, and if so, what are the legal and procedural requirements for obtaining such relief?
Parties in patent litigation may seek declaratory relief on the issues of infringement and validity. In practice, accused infringers very often assert counterclaims asking the court to declare that the asserted patent is invalid or not infringed. For an accused infringer to file a first-instance complaint seeking declarations of invalidity or noninfringement, a case or controversy needs to exist. That is, courts will apply a totality-of-the-circumstances test to determine whether there is “a substantial controversy, between parties having adverse legal interests, of sufficient immediacy and reality to warrant relief.”.
What are the costs typically incurred by each party to patent litigation proceedings at first instance? What are the typical costs of an appeal at each appellate level?
Costs in patent litigation include attorneys’ fees and various types of disbursements. Disbursements often include expert witness fees, travel and lodging costs, document processing costs, court reporter and videographer costs, translation or interpretation costs, jury or witness consultants, and others. On appeal, the disbursements are much more limited. Costs for appeals mainly involve document printing and binding, travel, and lodging.
Can the successful party to a patent litigation action recover its costs?
In the United States, there is no “loser pays” rule. Instead, attorneys’ fees and other costs are discretionary and not recoverable unless the court finds the case to be “exceptional” (i.e., it stands out with respect to (1) the substantive strength of a party’s litigation position, or (2) the unreasonable manner in which the case was litigated).. The award of attorney’s fees and costs can be limited or significant, but overall such awards are rare. Consequently, litigants in the U.S. usually do not engage in strategic decision-making with a goal of recovering costs in a case.
What are the biggest patent litigation growth areas in your jurisdiction in terms of industry sector?
In recent years, the technological fields with the most patent litigation include biotech/pharmaceutical, computer hardware and electronics, and software. Emerging areas of technology that may see more litigation in the future include biologics, cybersecurity, artificial intelligence/machine learning, autonomous transportation, machine vision, and robotics.
What do you predict will be the most contentious patent litigation issues in your jurisdiction over the next twelve months?
Patent eligibility under 35 U.S.C. § 101 continues to be uncertain and a contentious issue in patent cases. Courts began invalidating business method and financial services patents in 2008. That trend accelerated after the Supreme Court’s Alice decision in 2014 and now impacts various fields of technology. In January of 2019, the USPTO updated its examination guidelines, which help to increase allowances for patent applications including for those that might previously have been rejected under § 101. However, the Federal Circuit has made clear its precedent, and not the USPTO guidance, controls. Many have suggested that legislative action is needed to clarify the boundaries for § 101, but until those efforts are successful the issue will likely remain a hotly contested and litigated issue in the United States.
The rising use of discretionary denials of IPR petitions and legal framework of the PTAB are also highly contentious issues. Recently, in United States v. Arthex Inc., the Supreme Court held that the PTAB’s administrative patent judges were unconstitutionally appointed, and that the remedy for this issue was Director review of all IPR decisions at the USPTO. The exact ramifications of this decision are still in flux, and may lead to further disputes about the constitutionality of IPR proceedings, and the structure of these Director reviews.
Which aspects of patent litigation, either substantive or procedural, are most in need of reform in your jurisdiction?
As stated previously, the boundaries of patent eligibility under 35 U.S.C. § 101 are in need of legislative and policymaking attention in the United States. Congress has proposed legislation to clarify the application of § 101, especially the exclusion for “abstract ideas.” However, nothing has materialized yet and further efforts are needed to provide more clarity around § 101.
Venue, and forum shopping generally, have also been considered for reform. While TC Heartland LLC v. Kraft Foods Group Brands LLC, 137 S. Ct. 1514 (2017) confirmed that patent suits may be brought in districts where the defendant “resides” (i.e., their state of incorporation), there are still venue disputes based on where a defendant has a “regular and established place of business.”
Recently, there has also been attempts to amend Section 337 to limit litigation in the ITC by NPEs. Among other things, these proposals address how an NPE may satisfy the “domestic industry” requirement for an ITC proceeding, especially what would be required in terms of relying on the activities of a licensee to demonstrate a domestic industry.
What are the biggest challenges and opportunities confronting the international patent system?
From a global perspective, there remain differences regarding the perceived adherence to the “rule of law” and the independence of the courts. In countries where these principles are viewed with scepticism, there are fewer patent applications filed and fewer lawsuits commenced. Also, in emerging countries, the body of law concerning patents may be limited or spotty. This results in a lack of predictability and confidence for parties considering patent rights and enforcement in those countries. These issues present challenges for companies that compete domestically and abroad. But opportunities also exist because as the legal systems of the world grow more mature and experienced, patents may play a greater role in a larger number of countries and provide more options to parties and promote global economic activity.
NPE litigation is also a phenomenon affecting more countries today and likely into the future. Ten years ago, NPE lawsuits were principally filed in the United States. Now NPE suits are being filed in Europe and Asia. In countries where the patent laws are well-established and a permanent injunction is the typical remedy for infringement, an NPE can implement a global enforcement strategy that reaches more entities. Consequently, the uptick in NPE litigation has led to policy debates and proposed legislative reforms. NPE litigation has also created tension in the area of standard-essential patents (SEPs), where there are broad classes of alleged infringers (e.g., end-users, resellers, and manufacturers). Damages disputes have also arisen as to the determination of a fair, reasonable, and non-discriminatory (FRAND) royalty rate for SEP patents and whether a national court can decide both a domestic and global FRAND rate.
