Summary Judgment Non-Infringement

Today, in Personal Audio v. Google, C.A. No. 17-1751-CFC-CJB (D. Del.), Judge Burke addressed an apparent request for the Court to find non-infringement based on a claim construction issue, which came up for the first time in the context of a Daubert motion to exclude expert testimony.

The Court expressed some initial sympathy for the non-infringement argument, suggesting it may have had some merit:

[T]he Court notes more generally that the issue underlying Defendant’s Motion is Defendant’s assertion that the claim construction for “sequencing file,” . . . requires that “you can’t use a copy of the sequencing file to control playback and respon[d] to …

What Does It Take for "Unclean Hands" and "Prosecution Laches" Affirmative Defenses to Actually Survive a Motion to Strike?

Motion to Strike Affirmative Defenses

Defendants in patent cases often seem to throw in somewhat obscure affirmative defenses with little or no factual support. "Unclean hands" is a classic example. Defendants will sometimes seem to include defenses like unclean hands and prosecution latches with no real factual support (and, I suspect, not always the best grasp on what those defenses really mean).

Judge Stark issued an opinion today on a motion to strike "unclean hands" and "prosecution laches" defenses offers an example of what happens when a defendant actually does adequately support these defenses.

First, the standard: to succeed on a motion to strike affirmative defenses, the insufficiency must be "clearly apparent":

Stay Motion Denial Results in Guidance for the Parties—and for the PTAB

Motion to Stay IPR

Stay!

Pre-institution stays can be tough to achieve, but they are sometimes granted. Even when denied, though, a pre-institution stay may have other benefits, including that the Court may be willing to offer guidance on what to do—and what may happen—if the IPR is instituted.

An order from Magistrate Judge Burke on Friday is a good example. In eBuddy Technologies B.V. v. LinkedIn Corporation, C.A. No. 20-1501-RGA-CJB (D. Del.), the defendant moved for a pre-institution stay pending IPR. Judge Buke denied it:

ORAL ORDER: The Court, having reviewed Defendant's motion to stay the case pending resolution of [un-instituted] inter partes review ("IPR") proceedings . . . , hereby ORDERS that the Motion is DENIED without prejudice to renew in light of the following: (1) For reasons it has previously expressed, the Court is not typically inclined to grant a stay in favor of IPR proceedings when a case has been moving forward for a while and when the PTAB has not yet determined whether to initiate review of any of the patents-in-suit. . . . .; (2) That outcome seems particularly ...

What Are Technology Tutorials in Patent Cases, and Are They Worth It?

Technology Tutorial Summary Judgment

In the District of Delaware, five of our eight judges use form scheduling orders that provide a deadline for the submission of a "Technology Tutorial" around the time of claim construction.

Former Judge Stark required the parties to submit a tech tutorial in patent cases with the opening claim construction brief. Judge Stark's form order, for example, provided that:

Tutorial Describing the Technology and Matters in Issue. Unless otherwise ordered by the Court, the parties shall provide the Court, no later than the date on which their opening claim construction briefs are due, a tutorial on the technology at issue. In that regard, the parties may separately …

Chief Judge Connolly Bifurcates Patent Trial: Infringement First, then Invalidity, Damages, and Willfulness

Trial Trial Procedure

Bifurcation into liability and damages phases used to be common, with former Judge Robinson often splitting liability and damages, at one point saying that “bifurcation is appropriate, if not necessary, in all but exceptional patent cases.” Dutch Branch of Streamserve Dev. AB v. Exstream Software, LLC, C.A. No. 08-343-SLR, 2009 U.S. Dist. LEXIS 76006, at *2 (D. Del. Aug. 26, 2009).

These days, bifurcation still happens here, but it is a bit less common than it was back then.

Earlier this month, though, Chief Judge Connolly raised bifurcation in a way I hadn't heard of, suggesting that the parties split infringement from invalidity and other issues, with jury deliberations in between:

Likelihood of Stay Pending IPR in W.D. Texas vs. Delaware

Emily DiBenedetto, Feb. 23, 2022
IPR Stay

Today, we analyze the District of Delaware's propensity to grant stays pending IPR decisions, as compared to the Western District of Texas. Here are the big takeaways:

  • Prior to IPR institution, motions to stay are almost always denied in D. Del.;
  • Judge Albright of W.D. Tex. has denied 40% of motions (i.e. two motions) to stay pending instituted IPRs, but there is not much data available yet;
  • D. Del. has denied about 28% of motions (i.e. 16 out of 58) to stay pending instituted IPRs in the last four years;
  • D. Del. receives far more motions to stay pending IPR than W.D. Tex., and grants them just over half the time (~60% in the last 4 years, …

Chief Judge Connolly Limits Parties to 10 Claim Terms (Or, Why It's Helpful to Pay Attention to Seemingly-Obscure Precedent)

Andrew E. Russell, Feb. 23, 2022
10 Terms Stipulation

As frequent readers of this blog already know, some judges in Delaware have limited parties to a total of 10 terms for construction across all asserted patents.

We've noted at least one previous instance where Chief Judge Connolly seemed to limit the parties to 10 claim construction disputes. Last week, the Court made an even clearer statement on the issue.

The parties in MG FreeSites Ltd v. ScorpCast, LLC, C.A. No. 20-1012-CFC-JLH (D. Del.) filed their joint claim chart in advance of claim construction, and listed 15 terms in dispute. They also included a footnote smartly noting Chief Judge Connolly's practice not to permit argument on indefiniteness at the claim construction stage.

They then filed a stipulation …

Your IPR Succeeded? Congrats! Now Go to Trial on Infringement, But You're Estopped from Claiming Invalidity

Collateral Estoppel IPR

During some research the other day, I came across the below order that Judge Noreika issued last summer.

A defendant had moved in limine to exclude three of the four asserted claims of a patent from trial, after it prevailed on those claims in an IPR. Easy motion, right?

No. Judge Noreika held that, under Federal Circuit precedent, collateral estoppel does not prevent plaintiff from asserting those claims at trial until the decision is final. And the decision is not final until the appeal is exhausted:

Federal Circuit case law suggests that an IPR decision does not have preclusive effect until that decision is either affirmed or the parties waive their appeal …

Court Declines to Adopt Report & Recommendation, Grants Early Summary Judgment of Non-Infringement

Andrew E. Russell, Feb. 1, 2022
SJ Summary Judgment

Clients and co-counsel often ask whether it makes sense to object to an R&R issued by a Magistrate Judge. The answer depends on many factors. For example, why was motion denied? What are the chances it will be reversed? What is the client's commitment level to the case? What is the impact of the motion on the case? Etc.

Sometimes, though, what people really want to know is "would the district judge ever decline to adopt an R&R?" The answer to that is that yes, the court will sometimes declines to adopt an R&R, but it is definitely the less common outcome.

Yesterday, Judge Andrews did just that: he declined to adopt an R&R on a motion …

Section 284 Does Not Actually Say "Willfulness": Court Dismisses Willfulness Claim, Allows § 284 Treble Damages Claim to Proceed

Willfulness § 285

Triple Damages

We've written a lot on the developing case law in Delaware around willfulness and motions to dismiss. Willfulness requires knowledge of the infringement, and some of our judges have dismissed willfulness claims because the filing of a complaint for patent infringement cannot serve as the basis of knowledge of infringement.

Today, Judge Andrews followed that case law, and dismissed a willfulness claim in an amended complaint, stating that the original complaint cannot serve as a basis for establishing knowledge:

iFIT also alleges that Peloton knew of the '407 patent as of the filing of its original complaint. . . . I think this is irrelevant. My view is that an amended complaint cannot rely upon the …
