A Blog About Intellectual Property Litigation and the District of Delaware

Whenever collateral estoppel comes up in a patent case, it usually generates some interesting discussion. Yesterday's decision from Judge Andrews in TQ Delta v. 2Wire is no different.

After the Federal Circuit reversed a PTAB determination of unpatentability on an unasserted claim, the plaintiff moved to estop the defendant from challenging the validity of two related claims in the district court litigation.

Judge Andrews concluded that summary judgment was inappropriate because the defendant adequately "explained how the differences between the [asserted claims] and [the adjudicated claim] alter the invalidity analysis[,]" but he also addressed an interesting question: Is a petitioner "fully represented" in an IPR when another petitioner is taking the laboring oar before the PTAB?

District of Delaware

The Delaware FBA held its annual meeting virtually today. It included really wonderful speeches by the judges, passing along the Chief Judge gavel in both the district court and the bankruptcy court.

The FBA also did a great job presenting the event via Zoom (did anyone else clap while sitting alone in their offices, or was it just me?!).

I won’t try to summarize everything that was said, consistent with our ongoing attempts—and failures—to keep our posts short. But here are some quick highlights that may be particularly relevant to IP/DE readers:

  • Chief Judge Stark passed the gavel of Chief Judge to Judge Connolly, who will be new Chief Judge following the end of Judge Stark’s term …

Industry standards can be helpful for a patentee tasked with proving infringement of standard-compliant products. Standards often lay out mandatory features, such that a patentee may be able to use infringement of the standard itself as a shortcut to establish infringement of a standard-compliant product (although there are limits on that type of proof, including that the patent must cover all possible implementations of the standard).

The question of whether infringement by a standard can be used to shortcut infringement proofs for a product recently came up before Judge Andrews on a summary judgment motion by the plaintiff in TQ Delta, LLC v. 2Wire, Inc., C.A. No. 13-1835-RGA.

The defendant's products in TQ Delta were accused of implementing an infringing functionality . . .

The parties in Progressive Sterilization, LLC v. Turbett Surgical LLC, C.A. No. 19-637 (D. Del.) brought a dispute about "excessive" redactions to certain production in their patent action.

The defendant sought information from third parties who were under contract with the plaintiff, including various consultants and a former business partner.

Plaintiff apparently has confidentiality agreements with these people, and tried to filter their document production in the case, redacting information it thought should not be produced to the defendant. According to defendant's letter brief:

[Plaintiff] insisted on reviewing [the] third-party subpoena recipients’ responsive documents and redacting certain non-privileged content . . . prior to their production to Defendants

Here's a new one: A defendant in Natera, Inc. v. ArcherDX, Inc., C.A. No. 20-125-LPS (D. Del.) wanted to delay the trial to coordinate the schedule with another case involving an overlapping patent. So it filed a letter asking for leave to file a 3-page letter briefs, or to have a teleconference:

Given the parties have been unable to agree on an appropriate approach for coordination of both cases, we respectfully request leave to submit the competing views to Your Honor during a status conference or 3-page letter briefs.

Chief Judge Stark denied the request, directing the parties to file a motion instead:

ORAL ORDER: Having reviewed the parties' letters . . . relating to [the …

We at IPDE have chronicled the Court's efforts to limit the number of terms it construes pretty extensively. Just last month, we discussed Judge Noreika's opinion in Sentient Sensors, LLC v. Cypress Semiconductor Corp., C.A. No. 19-1868-MN (D. Del. May 17, 2021) where she shot down the plaintiff's motion to reconsider one of her claim construction rulings, citing O2 Micro.

This week, there are some further claim construction developments worth talking about—but we'll start first with some interesting history that we overlooked last time around.

A Difficult Claim Construction Journey

Although we didn't discuss it in our previous post, this case had already had a tempestuous claim construction process. The parties had initially submitted 8 disputed …

Judge Hall today issued an R&R on attorneys fees in In Re Kerydin (Tavaborole) Topical Solution 5% Patent Litigation, MDL No. 19-md-2884-RGA (D. Del. June 23, 2021), an ANDA case.

There, the plaintiff filed suit on four patents even though the PTAB had previously found an earlier patent in the family invalid in an IPR, and even though IPRs were pending on each of the four patents-in-suit.

Filing suit triggered the 30-month stay of FDA approval. Shortly after the suit was filed, one of the defendants moved to stay; plaintiff did not oppose, and actually filed a cross-motion to stay its own action against the other defendants (who opposed).

The Court granted the …

Last month we wrote about Judge Andrews' order that a plaintiff who won a default judgment against Aston Martin, LLC must file any settlement agreements from seven other patent suits, in order to help the Court determine the proper damages award.

Plaintiff has now responded.

We wondered in our last post whether the Court would permit plaintiff to file under seal. The answer is yes: the Court found the following short paragraph from the briefing to be sufficient to permit filing the settlement agreements and settlement amounts under seal:

Good cause exists to seal these Settlement and License Agreements. The Agreements contain confidentiality clauses such that if the documents were not filed under seal, Plaintiff might be in breach …

As we mentioned in our last post, Judge Bibas of the Third Circuit has taken two D. Del. patent cases by designation, along with a number of other cases.

I've seen a number of his opinions in other cases come through over the course of the year. They are easy to identify, as his writing style differs from any other judge we've had, in a way that is interesting to see.

One particularly notable opinion of his issued back in March, and apparently slipped our notice at the time. In it, he denies an FRCP 12(b)(6) motion, holding that a defendant's own patents can serve as circumstantial evidence that its products practice the claims, if those patents describe an infringing configuration. ...

For the first time, Judge Stephanos Bibas of the Court of Appeals for the Third Circuit has taken at least two patent cases by designation in the District of Delaware this year (along with a number of non-patent cases):

  • TexasLDPC Inc. v. Broadcom Inc., C.A. No. 18-1966-SB (D. Del.)
  • Boston Scientific Corporation et al v. Micro-Tech Endoscopy USA Inc., C.A. No. 18-1869-SB (D. Del.)

We mentioned Boston Scientific earlier this week; it was set to go to a jury trial July 12, 2021.

On Wednesday Judge Bibas entered the following order on the docket, staying the case one day before the pretrial conference:
