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 …

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 …

The Federal Circuit's decision is below.

It found that even though the defendant did not receive an identification of asserted claims from the plaintiff until after the statutory IPR deadline, and even though the patents included a total of 830 claims, the statute did not allow the defendant to file a new IPR petition and then join it to its previous IPR proceeding as a way to add claims after the statutory filing deadline.

The Court recognized that the decision would result in wasted efforts by defendants in challenging claims unnecessarily:

We . . . recognize that our analysis here may lead defendants, in some circumstances, to expend effort and expense in challenging claims that may ultimately never be asserted …

In an appeal from a Judge Battalion case in the District of Delaware, the Federal Circuit today held that—unsurprisingly—a jury may answer the fact question of whether a patent is standards essential.

It held that the argument to the contrary, that the Court must determine whether a patent is standards-essential during claim construction, was based on a misreading of precedent.

The Federal Circuit today reissued its March 2020 opinion in Illumina, Inc. v. Ariosa Diagnostics, Inc., which held a "method of preparation" claim relating to a natural phenomenon was patent eligible.

The reissue follows a petition for rehearing.

The patents involve a method for preparing a fetal DNA sample using a blood sample from a pregnant mother, by sorting the DNA fragments and removing the smaller ones using a size threshold.

The Original Bucket-Based Analysis

The Court originally described how it has consistently rejected "natural phenomenon"-related claims that fall into a "diagnostic" bucket, but has permitted method of treatment claims:

This is not a diagnostic case. And it is not a method of …

This morning, Docket Navigator covered Judge Bryson's D. Del. discovery opinion that was made public this week, focusing on his denial of a motion to strike errata to a 30(b)(6) deposition transcript.

But there are (at least) three other interesting points about the errata in the opinion:

  • COVID issues make deposition errata more necessary:
Mr. Rothrock had to prepare for his deposition under difficult circumstances, including having to consult remotely with others in the company. Mr. Rothrock understandably could have made a mistake during his deposition in light of the numerous topics and challenging circumstances in which he was forced to prepare. Given those circumstances, I will not disregard Mr. Rothrock’s errata.
  • The Court noted that, as usual, …

A few weeks ago, I suggested that, despite Berkheimer, courts are still taking § 101 motions to dismiss seriously when the facts warrant it. The Federal Circuit just affirmed the grant of one such motion in Data Scape Ltd. v. W. Dig. Corp., No. 2019-2161, 2020 U.S. App. LEXIS 20630 (Fed. Cir. July 1, 2020).

Reading Data Scape, it is interesting that the Court was able to shortcut the Alice Step 1 analysis by simply citing a 2016 Federal Circuit decision holding that the exact idea at issue—"the concept of delivering user-selected media content to portable devices"—was abstract.

In my view, this is one way that, over time, § 101 motions are …
