Judge Connolly Takes a Stand on Post-Complaint Knowledge

David M. Fry, March 24, 2021
Willfulness Indirect Infringement

As we pointed out last July, Judge Connolly has publicly questioned (several times) whether post-complaint knowledge is enough to state a claim for willfulness or indirect infringement. Today, he answered that question with a resounding no.

In nearly two full pages of footnotes, Judge Connolly collected the conflicting authority across the nation—and within the district—on whether an infringement complaint, by itself, is enough to support the knowledge element of willful and indirect infringement claims.

He went on to explain his own views:

ZapFraud has identified, and I know of, no area of tort law other than patent infringement where courts have allowed a plaintiff to prove an element of a legal claim with evidence that the plaintiff filed …

Physically Impossible = Indefinite

Andrew E. Russell, March 23, 2021
Indefiniteness Summary Judgment

The nailgun at issue.
The nailgun at issue. US Pat. No. 7,156,012

Judge Connolly granted summary judgment of invalidity this week, finding three claims indefinite due to their physical impossibility.

The patent relates to a faster air-powered nail gun, which uses a trigger to control the gun by providing "fluid communication"—i.e., air flow—between air valves.

All of the patent's claims involve triggers and "fluid communication" of various sorts, but defendants picked up on some weird phrasing in one independent claim:

a trigger valve exterior frame to which the main valve control channel is fluidly connected;

Defendants argued that the "exterior frame" is solid and can't be "fluidly connected" to the trigger.

Plaintiffs disagreed, arguing that a person of skill in the art would …

Final Score Card for the March 12th § 101 Day Hearing

Andrew E. Russell, March 22, 2021
§ 101 Days § 101

On Friday, Chief Judge Stark released his opinion summarizing his bench rulings from his most recent Section 101 day. This is how the patents fared:

Content Square v. Quantum Metric, Inc., C.A. No. 20-832-LPS (D. Del.)

In the first case, Content Square, the Court invalidated the claims of 2 of the 5 asserted patents.

The invalidated patents related to "heat map patents," which relate to displaying heat maps of web browsing data. These include U.S. Patent Nos. 10,063,645 and 10,079,737.

The third patent, which was not invalidated, related to "creating multiple versions of a website to determine users' preferences." Interestingly, the Court held …

The District of Delaware's local rules are available on the court's website, but they don't tell the whole story—there are a number of critical rules and practices set forth in other documents that are not as obvious on the site.

These can really trip you up if you're not familiar with D. Del. practice.

This post is geared towards mainly towards out-of-town or in-house counsel. It covers the basics and then lays out where to find some of those other important rules if you have a …

The Rare Daubert Motion That Consistently Succeeds

Nathan R. Hoeschen, March 18, 2021
Damages Daubert

Daubert motions are as tough as they are common. It seems every case spawns at least one on each side, and the vast majority are denied with the Court finding that any deficiencies in the expert's methodologies are merely grounds for exploration on cross-examination.

One type that consistently beats these odds (at least in Delaware) is directed to damages experts that attempt to use the damages figures from prior jury verdicts as starting points for a hypothetical negotiation.

Judge Andrews in particular has held a hard line on this issue as shown in his decision on Wednesday in Sprint Communications Company L.P. v. Charter Communications, Inc, C.A. No. 17-1734-RGA, D.I. 573 (D. Del. Mar. 16, 2021). …

Judge Burke Chides Parties for Time-Wasting Motion to Strike

David M. Fry, March 17, 2021
Motion to Strike Pennypack

We've written several posts about the Pennypack factors and how hard it can be to win a motion to strike in D. Del. The upshot is that it's often better to simply reach agreement on a curative remedy rather than spend time on full-blown motion practice.

Case in point: on Monday, Judge Burke denied a motion to strike a two-page supplemental expert declaration on a patentability issue. Applying the Pennypack factors, he concluded

that having to respond to the supplemental declaration (which, after all, relates to one discrete issue, and is only two pages long) would occasion some great prejudice to Defendants. The issue can be resolved by permitting Defendants to file a supplemental sur-rebuttal expert report on …

I Don't Object, Your Honor!

Jeff Castellano, March 16, 2021
R&R Section 101

Objections to Reports and Recommendations are something like an appeal. The District Judge is tasked with addressing the alleged errors of the Magistrate Judge de novo only to the extent they are "properly objected to." Fed. R. Civ. P. 72(b)(3). Thus, it is the job of the parties to raise objections to an R&R in a procedurally proper way. If they fail to do so, the District Judge is hamstrung to an extent. This outcome was on display in a recent ruling by Judge Andrews, in which both sides failed to properly object to a portion of the Magistrate Judge's R&R, leaving a patent with "serious" validity problems alive (for now).

The Delaware Supreme Court recently announced their expectation that they can safely return to jury trials in June, noting the recent decline in COVID-19 cases. They also announced that the 2021 bar examination for will be administered remotely.

The District of Delaware, however, is still set to restart jury trials on April 5. But there have been a few changes to D. Del.'s April jury trial calendar since our last update:

Judge Andrews: Claim Not Indefinite, Despite Possible Drafting Error

Indefiniteness Claim Construction

Claim construction opinions tend to be highly fact-specific, so even though they can be critically important to the parties in a case, we don't always post about them on this blog.

Judge Andrews issued an interesting claim construction opinion today, however, which addressed indefiniteness due to a potential drafting error in a claim.

The opinion involved claim language for a mechanical device:

. . . wherein the . . . assembly comprises a housing comprising the syringe and the stirring motor . . .

Defendants argued indefiniteness in light of the dual use of "comprising," because a person of skill in the art cannot determine a …

Are Your Citations "(cleaned up)"?

Andrew E. Russell, March 12, 2021
Legal Writing

Law360 published an article yesterday by Carrie Garrison about an "exciting shift in the legal world," after Justice Thomas used the parenthetical "(cleaned up)" in a SCOTUS opinion:

Under that doctrine as it existed in 1946, a judgment is “on the merits” if the underlying decision “actually passes directly on the substance of a particular claim before the court.” Id., at 501–502 (cleaned up).

This parenthetical, as Ms. Garrison points out, was suggested in 2017 as an alternative to longer parentheticals like "(internal quotation marks omitted)" under Bluebook Rules 1.5 and 5.2.

This sounds like a great way to save some space, particularly in light of the ongoing adoption of word limits by the District of Delaware …
