Following on Yesterday's post where we noted the odd and pleasing use of "Kludgy," I would like to use today's post to bring attention to another recent Delaware opinion which contains what I can only assume is the only use of the phrase "[y]ou can work with legal but at the end you will have your face burried [sic, obviously] in s***!" in a legal opinion.

The case is Citrix Systems, Inc. v. Workspot, Inc., C.A. No. 18-588, D.I. 411 (D. Del. Sept. 25, 2020), and it is a true ray of light in these dark days.

The opinion describes …

In ruling on § 101 motions to dismiss, the Court typically adopts plaintiff's constructions outright, if plaintiff offers any. Those constructions may or may not be enough to avoid dismissal, but I can't recall any instance where the District of Delaware actually had to reject a construction as implausible under the FRCP 12(b)(6) standard.

Until now. In Synkloud Tech. v. HP, Inc., C.A. No. 19-1360-RGA (D. Del. Sep. 28, 2020), plaintiff tried to bake the § 101 "non-conventional" standard into the proposed claim construction. Clever! But Judge Andrews described the problems with that approach as "self-evident":

Plaintiff states that a person of ordinary skill …

This blog could be nothing but disputes about claim narrowing. We'd have 72,000 posts a year and we'd never get to the bottom of all the little sub-disputes, and how each judge prefers to handle them. I'm sure it would be quite popular.

This week in IPA Technologies Inc. v. Amazon.com, Inc., Judge Andrews clarified his position on one of the more common disputes -- how exactly to count "references" for the purposes of narrowing.

The defendant, Amazon, had been ordered to reduce the number of references in its invalidity contentions and had responded by limiting itself to 4 prior art "systems." …

Today the Federal Circuit held that a party joining an existing IPR is not subject to estoppel on any grounds other than those that were actually raised. See the opinion below.

Before this, a plaintiff could argue that a defendant who joined an in-progress IPR was estopped on any anticipation or obviousness arguments that "reasonably could have [been] raised" in the IPR.

The Court here held, in short, that because a defendant joining an existing IPR is not allowed to add new grounds at all, it cannot be estopped except on those grounds actually raised.

It relied on the Facebook decision we talked about …

It's interesting that the Court is now regularly offering public access information for remote hearings. I can't recall it doing that before the coronavirus.

The only pre-coronavirus remote hearings I can think of were for scheduling and discovery dispute conferences, where public access is not usually a concern. Scheduling conferences often took place privately in chambers even when they were in-person, and discovery dispute conferences often involve confidential information anyway. It looks like they judges are still handling these how they always have.

These days, however, the Court regularly holds all kinds of other, more substantive hearings remotely, and most of the judges have been taking steps to allow the public to attend. Here is what the judges have been …

In an opinion today, Judge Andrews laid out his updated thoughts on transfer motions, particularly in light of COVID-19 travel restrictions and the related difficulties.

Here are some interesting points re: his views:

  • In granting transfer, he focused on the fact that the Plaintiff's principal place of business was not Delaware
  • He held that convenience of counsel is irrelevant, because parties can choose their counsel.
  • As far as court congestion, he noted that "[o]ne other Delaware judge and I each individually had more old cases than the entire Western District [of Washington]," and that the Judicial Conference has recommended …

Judge Bryon issued an interesting stay opinion last Friday.

The plaintiff had initially asserted six patents. Of those, four were dismissed under § 101, and the claims as to one of the remaining patents were severed and stayed pending IPR.

The case was set to go to trial on the last remaining patent on November 30, just over 11 weeks from the date of the order. But, last month, the PTO granted a request for ex parte reexamination of the sole asserted claim of that patent.

Shortly after that, Judge Bryson issued his opinion granting a motion to stay pending re-exam. A couple of interesting points:

  • What a turnaround! Defendant first indicated it intended to request a stay …

Judge Noreika had a rare holding estopping a plaintiff from asserting the lone patent-in-suit patent due to collateral estoppel after trial.

The Court held a five-day bench trial in Biogen Int'l GmbH v. Amneal Pharms. LLC, C.A. No 17-823-MN in December 2019, dealing with a host on invalidity issues, including obviousness, enablement, and written description. The parties completed post-trial briefing in March 2020, and and a final opinion was thus expected in the not-too-distant future.

Unfortunately for Biogen, they also sued a different defendant, Mylan, in the Northern District of West Virginia on the same patent. That case went to trial in February 2020, on the sole …

Judge Andrews yesterday issued his opinion denying all post-trial motions in TQ Delta, LLC v. 2Wire, Inc., C.A. No. 13-1835-RGA (D. Del.). The jury had returned a verdict of infringement and no invalidity after a trial in January 2020.

One part of the opinion stands out—Judge Andrews discusses his decision to preclude the defendant from discussing the full prosecution history of the patent before the jury as prejudicial under FRE 403:

I ruled that 2Wire could elicit testimony about what prior art was in front of the patent examiner, but that testimony about a “lengthy history of cancelling claims, adding claims, rejecting claims, [and] rejecting new claims” was inadmissible under Federal Rule of Evidence 403 because …
