A Blog About Intellectual Property Litigation and the District of Delaware

We wrote last month about the "mansplaining brief," which caught some eyes around town when it (and the declaration attached to it) accused the Court of "gender harassment and discrimination."

We set out the full background in our post, but generally the Court ordered the sole member of a Mavexar-related LLC to attend a hearing here in Delaware.

She then filed a motion for reconsideration offering numerous objections, including among other things that (1) the Court had no power under FRCP 45 to compel her attendance, since she lives in Texas; and (2) that she is a working mother and therefore unable to travel to Delaware.

(She also said that she "feels harassed" by …

Here's one you don't see every day. Back in March, Judge Burke granted a § 101 motion to dismiss as to the claims of two of the six asserted patents in Topia Technology, Inc. v. Egnyte, Inc., C.A. No. 21-1821-CJB (D. Del. Mar. 31, 2023).

In that opinion, the patentee did not dispute that the claims were directed to the abstract idea of synchronizing a file across a network:

Plaintiff, for its part, does[ not] dispute that synchronizing multiple versions of a file across network computers is an abstract idea, and the Court agrees that it is. Again, …

We've written a lot about the common D. Del. practice of limiting parties to 10 claim terms per case (at least for the Markman hearing).

We talked about a similar order from Judge Andrews earlier this month, and previous orders by Judges Connolly, Noreika, and Burke. Now, Judge Williams has set the same limit, in at least one action:

ORAL ORDER: Having reviewed the parties' Joint Claim Construction Brief (D.I. 96), IT IS HEREBY ORDERED that the Court will construe a maximum of ten (10) terms/term sets during the August 1, 2023 Claim Construction Hearing. The parties shall meet and confer and, no later than July 17, 2023, the parties shall file …

At this point, all of the D. Del. judges have adopted a joint claim construction brief procedure invented by Judge Andrews, where the parties serve opening, answering, reply, and surreply briefs, and then file a single combined joint claim construction brief that presents the arguments term-by-term. This means that the parties and the Court can work from a final, combined joint brief where all of the arguments match up.

This is a great procedure and everyone seems to like it. Certain questions tend to come up about it, though.

Common Questions on the Joint Claim Construction Brief

"Sure, I had my LLC sue a bunch of people in Delaware, but I didn't think the Court would actually make me GO there." Andrew Russell, CC BY 2.0

I guess our post about the Mavexar hearing last week was remiss in failing to talk about the "mansplaining brief." I've had a couple of people ask me about it. Here is the background and some quick thoughts.

Chief Judge Connolly Orders Mavexar-LLC's Sole Member to Testify In Person

The short version of the leadup: Mavexar is an entity that creates LLCs to assert patents against tech companies for quick settlements, often in Delaware. The LLCs take all of the risk, and Mavexar keeps 90-95% of the profits while hiding its …

Backertop's—or Mavexar's—Two Attorneys
Backertop's—or Mavexar's—Two Attorneys AI Generated

The Court held a lengthy hearing in the Backertop cases today. These are Mavexar-related actions and, if you recall, they involve a Mavexar attorney and his wife, who he appointed as the sole member of a Mavexar patent assertion entity.

How a Patent Assertion Entity is Born

Some of the Court's questions focused on exactly what Mavexar does, and confirmed that they operate basically as set out in the earlier hearings.

Here, from the lawyer's perspective, Mavexar attorneys reached out and said that Mavexar wanted to start several litigation campaigns, and asked whether the attorney was interested. They said that they would figure out what entity would actually assert the patents later.

Judge Andrews issued an interesting order on Friday. Based on the docket, it looks like the parties had fully completed the Markman process (disclosures, meet-and-confer, joint claim chart, and joint brief), and had briefed a total of 16 terms. Judge Andrews then canceled the Markman and "dismissed" the briefing:

ORAL ORDER: The parties have submitted a joint claim construction with the request that I construe at least 16 terms including, for example, comprising and patient. I think that if I postpone the Markman hearing, some of these disputes may fall away. Therefore, the Markman hearing scheduled for June 23 is cancelled. The Markman briefing is dismissed. The …

Chief Judge Connolly issued a memorandum order in the Backertop case today. We talked previously about how the plaintiff in Backertop is an LLC whose sole member is a paralegal who is married to an attorney who works at Mavexar, who gets just 5% of the proceeds of litigating the patents owned by the LLC (the rest goes to Mavexar).

Following a hearing last year, the Court ordered production of various documents, and ordered the owner of the LLC to appear again for a hearing on June 8. She asked to attend remotely due to other obligations.

Today, Chief Judge Connolly denied her request, but rescheduled her appearance for July (the June 8 hearing will still …

Stick Figure Bonk

We talked early last year about how Judge Noreika praised Chief Judge Connolly SJ ranking procedures, and applied them in a case where the parties had filed 11 SJ motions.

As a reminder, under Chief Judge Connolly's procedures, the parties rank their SJ and Daubert motions. The Court addresses them in order, and if it denies one, it then denies the remainder.

Needless to say, it can lead to some significant strategizing prior to filing, where parties try to balance the importance of each motion with its likelihood of success.

This week, Judge Noreika did it again, and I thought it was a good time to remind everyone that this can happen. In VB Assets, LLC v. Amazon.com, Inc. …

On Wednesday, Judge Andrews issued an order in Salix Pharmaceuticals, Ltd. v. Norwich Pharmaceuticals, Inc., C.A. No. 20-430-RGA (D. Del. May 17, 2023) rejecting an attempt to evade judgment in an ANDA action based on the filing of an amended ANDA.

The defendant in the case had won on one method of treatment, and lost on the other. It filed an amended ANDA seeking to remove the infringing treatment from the label:

Defendant filed an ANDA seeking to make and market a drug for two different methods of treatment-the IBS-D indication and the HE indication. I had a bench trial. After trial, I ruled in Defendant's favor on the IBS-D indication (as …
