Abstract

The Supreme Court’s 2017 decision in TC Heartland LLC v. Kraft Foods Group Brands LLC, 581 U.S. 258 (2017), fundamentally restructured the patent venue landscape, displacing the Eastern District of Texas as the dominant forum for patent infringement litigation and redirecting a substantial volume of filings to the District of Delaware. In the years since, Delaware has absorbed that surge while simultaneously imposing greater procedural rigor, enhanced transparency requirements, and more demanding case management. This Article examines whether the District of Delaware remains a genuinely good forum for patent litigation—for plaintiffs and defendants alike—or whether its evolving practices have eroded the qualities that once made it attractive. The conclusion is that Delaware remains an excellent forum, but for reasons that have shifted considerably since the pre-TC Heartland era: its value today lies in judicial sophistication, docket reliability, and a mature body of patent-specific precedent, rather than in any perceived tilt toward either party.

I. Introduction

For practitioners who have navigated patent disputes over the past two decades, the District of Delaware has occupied a complicated position. It has long been a mandatory venue for suits against Delaware-incorporated defendants—a category that encompasses the majority of major U.S. technology and pharmaceutical companies—and it has developed one of the most experienced patent benches in the federal judiciary. Yet, its reputation has not been uniformly positive. Non-practicing entities have viewed it as procedurally demanding and structurally unfriendly. Operating-company defendants, while appreciating the court’s rigor, have sometimes found its docket pace and discovery obligations burdensome.

The question of whether Delaware is a good forum admits no single answer, because “good” depends entirely on who is asking and for what purpose. A forum that efficiently resolves meritorious disputes, applies the law consistently, and resists manipulation by either side is, by most measures, a good forum. Evaluated against those criteria, Delaware fares well. But that assessment requires honest engagement with both the court’s genuine strengths and the real challenges it presents to litigants.

II. The Post-TC Heartland Venue Landscape

A. The Statutory Framework and the Court’s Ruling

Patent venue is governed exclusively by 28 U.S.C. § 1400(b), which permits civil actions for patent infringement to be brought where the defendant resides or has committed acts of infringement and has a regular and established place of business. For decades, the Federal Circuit construed “resides” broadly, effectively permitting suit in any district where the defendant was subject to personal jurisdiction—a reading that concentrated filings in plaintiff-favorable jurisdictions, most notably the Eastern District of Texas.

TC Heartland reversed that course. Relying on Fourco Glass Co. v. Transmirra Products Corp., 353 U.S. 222 (1957), the Court held that “resides” for a domestic corporation means only its state of incorporation. 581 U.S. at 268–69. The Federal Circuit subsequently clarified the “regular and established place of business” prong in In re Cray Inc., 871 F.3d 1355 (Fed. Cir. 2017), requiring a fixed, geographically stable physical presence actually associated with the defendant.

B. Delaware’s Rise as the Default High-Volume Forum

Because Delaware is the state of incorporation for more than 60 percent of Fortune 500 companies and a substantial proportion of U.S. technology and pharmaceutical firms, TC Heartland effectively designated the District of Delaware as the mandatory forum for a large share of patent infringement suits.

The Western District of Texas briefly emerged as an alternative forum under Judge Alan Albright, whose case management practices attracted substantial plaintiff-side interest. However, Federal Circuit mandamus decisions imposing more rigorous transfer analysis—see, e.g., In re Apple Inc., 979 F.3d 1332 (Fed. Cir. 2020)—together with administrative reassignments within that district, have moderated WDTX’s role. Delaware has remained throughout these fluctuations the most consistent high-volume patent forum in the country.

III. Structural Features of Delaware Practice

A. Judicial Expertise

The most important feature of the District of Delaware as a patent forum is the quality of its bench. The court’s active patent judges—currently Judges Connolly, Andrews, Noreika, and Hall—have collectively presided over hundreds of patent trials and claim construction proceedings. They are conversant with claim construction methodology, patent damages frameworks, and the procedural demands of complex technical litigation in a way that distinguishes them from generalist judges in lower-volume districts.

That expertise matters practically. Parties benefit from Markman rulings that reflect genuine engagement with the technology and the intrinsic record. Damages analysis receives rigorous scrutiny. Experts who advance unsupported or methodologically deficient opinions are challenged. For litigants with strong cases—whether plaintiff or defendant—a sophisticated bench is an asset, not a liability. It is forums where judicial unfamiliarity with patent law creates unpredictability, not expertise, that litigants should fear.

B. Procedural Rigor and Docket Discipline

Delaware’s default scheduling orders impose tight deadlines for infringement contentions, invalidity contentions, claim construction briefing, and expert disclosures. Extensions require demonstrated good cause. The court enforces its schedules.

This disciplinary environment has a sorting function. Litigants with well-developed claim charts, coherent invalidity theories, and organized expert teams navigate the Delaware schedule without significant difficulty. Litigants whose cases depend on strategic delay, discovery abuse, or manufactured complexity encounter a court that has little tolerance for those tactics. For meritorious disputes—cases where the underlying questions of infringement and validity are genuinely contested and deserving of resolution—Delaware’s procedural rigor is a virtue.

C. Early Resolution of Patent Eligibility

Delaware’s bench has demonstrated meaningful willingness to resolve patent eligibility challenges under 35 U.S.C. § 101 at the pleading stage in appropriate cases. For defendants facing asserted patents of questionable eligibility—particularly software and business-method patents susceptible to challenge under Alice Corp. v. CLS Bank International, 573 U.S. 208 (2014)—early § 101 adjudication offers an efficient path to resolution before substantial discovery costs accumulate.

The court is not uniform on this point, and individual judges exercise varying degrees of receptivity to pre-claim-construction § 101 motions.[1] But the availability of early eligibility adjudication, in a court that will engage the question seriously rather than reflexively deferring it, is a meaningful feature for defendants asserting strong eligibility defenses.

D. Transparency and Disclosure Requirements

Judge Connolly’s standing orders requiring disclosure of third-party litigation funding arrangements, corporate ownership structures, and real-party-in-interest information represent the most consequential recent development in Delaware patent practice. These orders require plaintiffs to identify any entity with a financial interest in the litigation and to disclose the existence and terms of any litigation funding agreement.

From a systemic perspective, these requirements reflect a sound policy judgment: courts and parties should know who is actually prosecuting and financing a lawsuit. Defendants are entitled to assess whether conflicts of interest exist, whether adverse cost awards can be collected, and whether the nominal plaintiff is the real decision-maker. The practical effect of these disclosure orders—including the voluntary dismissal of cases by plaintiffs unwilling to comply—illustrates both their reach and their legitimacy. Whether they will be adopted more broadly within the district or survive any appellate challenge remains to be seen.

E. Jury Pool and Trial Dynamics

Delaware’s jury pool, drawn primarily from Wilmington and surrounding New Castle County, tends to be sophisticated and experienced with commercial and corporate litigation. Jurors are not predisposed to either plaintiff or defendant; they bring an orientation toward evidence and logical argument that rewards well-prepared trial counsel on both sides.

Delaware does not offer the probabilistic plaintiff-side advantage at trial that the Eastern District of Texas historically provided. But a neutral, sophisticated jury is, for most litigants with meritorious positions, exactly what the trial process should produce. The question for any litigant should be whether their case is strong enough to win before an attentive, unbiased jury—and if it is not, that is information worth having before trial.

IV. Why Delaware Remains a Good Forum

A. For Plaintiffs with Strong Cases

Delaware is an excellent forum for patent plaintiffs who have invested seriously in their cases. The court will apply the law faithfully, enforce scheduling obligations that keep defendants from running out the clock, and provide a sophisticated jury capable of understanding complex technology. Plaintiffs with valid patents, clear infringement theories, and sound damages analyses have every reason to expect a fair hearing.

The forum is less hospitable to plaintiffs whose strategy depends on leveraging discovery burden and litigation uncertainty to extract nuisance-value settlements.

B. For Defendants

Delaware’s procedural tools—early § 101 motions, rigorous claim construction, disclosure requirements, and judicial willingness to impose sanctions for litigation misconduct—give defendants meaningful opportunities for early case resolution and cost containment. Operating companies facing infringement suits, particularly from non-practicing entities, benefit from a court that takes gamesmanship seriously and does not permit plaintiffs to use the litigation process as a pure pressure mechanism.

C. Predictability as an Institutional Value

Whatever its demands, Delaware offers something no litigant should take for granted: predictability. The court’s experienced bench, well-developed local rules, and substantial body of patent-specific precedent allow practitioners to forecast scheduling, anticipate judicial tendencies, and manage litigation budgets with reasonable accuracy. In a landscape where many districts handle patent cases infrequently and inconsistently, Delaware’s reliability has significant institutional value for practitioners and clients on both sides of the docket.

D. Docket Velocity

Delaware cases typically reach claim construction within twelve to eighteen months of filing and proceed to trial within two to three years. That pace reflects a court that takes its docket seriously and does not allow cases to languish. For plaintiffs holding patents with limited remaining term, and for defendants seeking resolution rather than perpetual uncertainty, a court that moves cases to resolution is intrinsically valuable.

V. Conclusion

The District of Delaware is still a good forum for patent litigation. It may not be the forum it once was for litigants whose strategy depended on exploiting procedural asymmetries, favorable jury dynamics, or judicial unfamiliarity with patent law. But measured against the criteria that should matter—judicial sophistication, procedural fairness, docket efficiency, and resistance to manipulation—Delaware performs well by any serious standard.

Practitioners advising plaintiffs should approach Delaware with a disciplined, well-resourced litigation strategy. Cases built on strong patents, coherent claim charts, and defensible damages theories will receive a fair and efficient hearing. Cases built on leverage and opacity will encounter a court that has specifically adapted to address those tactics.

Practitioners advising defendants should recognize that Delaware’s procedural environment provides genuine tools for early case resolution. Early § 101 motions, disclosure requirements, and a bench experienced enough to identify weak cases quickly all serve defendants’ legitimate interests.

The District of Delaware is not a forum that rewards weakness on either side. For litigants with meritorious positions and the resources to prosecute them, that is precisely the point.

[1] Judge Stark had a procedure when he sat on the bench known as “101 day.” On 101 Day, the court heard 101 arguments for multiple cases and decided them early in the case. This did not bode well for patent holders, especially trolls who usually enforce tech patents.
