Court Refuses to Allow Expert to Evade Adverse Construction Via Doctrine of Equivalents

Andrew E. Russell, July 21, 2021
DOE Daubert

Yesterday, visiting Judge Bataillon excluded a patentee's expert opinion where the expert tried to use the doctrine of equivalents to skirt the Court's construction of a term.

The Court had initially rejected a preliminary injunction motion by the patentee, holding that it had failed to show a likelihood of success on infringement based on its proposed claim construction.

The patentee then proposed the same construction during claim construction before the magistrate judge, who issued an R&R rejecting it.

The patentee then objected to the R&R, but the Court adopted the construction in the R&R and again rejected the patentee's proposed construction.

Specifically, the Court held that the claims required two elements that each have a different thickness and composition: …

Arbitrability Goes to the Arbitrator, Judge Andrews Rules

Jeff Castellano, July 20, 2021
Arbitration Covenant

When parties seek to dismiss or stay a patent dispute in federal court in favor of arbitration pursuant to an agreement, someone needs to decide whether the parties' dispute falls within the scope of the agreement's arbitration provision (and is thus arbitrable). Whether that question is decided by the court or the arbitrator depends on the language of the agreement. So, in essence, the court must interpret the agreement for the limited purpose of divining the parties' intent (or lack thereof) to shunt arbitrability to the arbitrator.

In a recent order in Nidec Corp. v. Seagate Technology LLC, C.A. No. 21-52-RGA, Judge Andrews found...

Judge Bibas: "Deadlines are not suggestions. Litigants must respect them."

Substantial Completion FRCP 26

As we've discussed, parties sometimes treat the deadline for "substantial completion of document production" as a soft deadline, doing a "rolling production" afterwards that can be quite voluminous. An opinion from Judge Bibas today shows the risk of not taking that deadline seriously.

In the opinion, Judge Bibas excluded over 60,000 rows of spreadsheet sales data that were produced by a defendant in an Fair Labor Standards Act class action, after the defendant waited until six months after the deadline for substantial completion of document production to produce the data.

As usual for Judge Bibas, his opinion is an interesting read and a bit different from what we typically see from other judges in Delaware. …

Judge Fallon Pushes Back on Excessive Sealing

David M. Fry, July 16, 2021
Sealing

We've written about the strong presumption of public access in the Third Circuit, which has led the D. Del. judges to push back on sealing requests in recent years. Judges frequently deny requests to seal judicial records (like hearing transcripts and opinions), and some have taken a more active role in monitoring sealed filings on their dockets.

On Tuesday, for example, Magistrate Judge Fallon ordered a party to provide "a factually detailed explanation" for why the exhibits to the redacted version of a sealed letter brief met the Third Circuit standard for sealing:

ORAL ORDER TO SHOW CAUSE re: D.I. 161 : On or before close of business on July 14, 2021, Defendants shall submit a letter …

Failing to Sue Other Competitors Weighs Against Permanent Injunction

Injunction

Judge Stark issued an interesting opinion last week, deciding not to grant a permanent injunction. Although these requests are denied more often than not, this particular opinion was interesting because it rested, in part, on the plaintiff's conduct in failing to pursue third-party (alleged) infringers.

When it came time to rule on the permanent injunction issue, the Court had already determined that the parties in AO Smith Corp. v. Bradford White Corp., C.A. No. 18-412-LPS, D.I. 244 (D. Del. July 9, 2021) were direct competitors. AO Smith, D.I. 220 at 13 (D. Del Mar. 31, 2020). The relevant market also had two other substantial players not involved in the suit.

On Monday, Judge Noreika sanctioned a patentee plaintiff for not following the protective order regarding source code.

Here is what the plaintiff did:

Plaintiff violated the Protective Order at least six times over a period of almost one year by: 1) creating an electronic copy of the source code on July 6, 2020; 2) sending that electronic copy to a vendor that had not signed the Acknowledgement and Agreement to Be Bound by Stipulated Protective Order (which actually violated two provisions of the Protective Order); 3) failing to maintain a log of all copies; 4) storing an electronic and apparently unencrypted copy of the source code …

Some Notable Points from Magistrate Judge Hall's § 101 Denial in RSDI v. Lyft

Andrew E. Russell, July 12, 2021
§ 101 Days 12(b)(6)

Magistrate Judge Hall issued a § 101 R&R today in Rideshare Displays, Inc. v. Lyft, Inc., C.A. No. 20-1629-RGA-JLH (D. Del.), recommending denial of defendant Lyft's motion to dismiss based on § 101.

The Court found that the patent was not directed to an abstract idea—though it noted that it was a close call—and that, regardless, the invention contained an inventive concept under Step 2 of Alice.

We've all read about dozens (or more) of § 101 opinions over the last few years, but here are a few points of interest from Judge Hall's opinion:

  • Judge Hall closely examined the representativeness of the alleged representative claim, and rejected it as unrepresentative. Choose …

Claim Construction: Quasi-Intrinsic Evidence and Carryover Disclaimers

Jeff Castellano, July 9, 2021
Claim Construction

Judge Stark issued a claim construction ruling in a large multi-district ANDA case last week, touching on interesting questions regarding the nature of intrinsic evidence and the impact of disclaimers on child applications.

The parties to In re Entresto (SacubitriWalsartan) Patent Litigation, C.A. No. 20-2930-LPS presented the Court with just a few issues for resolution.

First, the Court considered whether independent claims of two of the patents-in-suit directed to administration of a "combination" of active ingredients should be limited to administering those ingredients as "two separate components“…

Daubert Time

ANDA Scheduling

Time

Judge Noreika issued an interesting order last week that allows us to pinpoint precisely how much time she requires to consider Daubert motions.

Naturally, we already had some insight into this issue from the Judge's form scheduling orders. For non-ANDA cases (i.e. cases where the parties may file summary judgment motions), Daubert motions are due at the same time as SJ motions—at least 4 months before the pretrial conference. See Form Scheduling Order [Patent, Non-ANDA], ¶ 8(f)(iii) (D. Del. Apr. 5, 2021) (Noreika, J.).

The form scheduling order for ANDA cases, on the other hand, gives the parties considerably more leeway, simply requiring that any Daubert motion be brought "no later …
