There are certain situations that come up over and over in patent cases. One of them is that a plaintiff will bring identical infringement suits against multiple defendants, and one of those defendants will then file an IPR or CBM proceeding before the patent office attacking the validity of the patents.

Under the America Invents Act, the filing party and any real party in interest are subject to estoppel. But unrelated defendants are not. The filing party will often move to stay the district court litigation. Generally speaking, parties with an instituted IPR or CBM review of all patents-in-suit often have pretty good chances of getting a stay.

So what happens when the defendants in …

We've discussed in the past how IPR stays are becoming increasingly common in the district. Judge Burke continued that trend last week in an order granting a stay pending IPR in what he termed a "tough call."

Defendants in Speyside Medical, LLC v. Medtronic CoreValve LLC, C.A. No. 20-361-LPS-CJB, D.I. 155 (D. Del. Sept. 30, 2021), filed IPR petitions against all 5 patents-in-suit, but the PTAB only instituted IPR's against 3 of the patents. Defendant then moved to stay the whole action and the plaintiff opposed. Both sides agreed that a partial stay was inefficient, and so Judge Burke treated the motion as an "all-or-nothing proposition."

Judge Burke began by noting that noting that the decision would be an easy one if the PTAB had instituted as to all of the patents-in-suit. Although this situation presented a closer call, given that the case would ultimately need to proceed as to at least 2 of the patents, Judge Burke granted the stay ...

An interesting fees issue was decided earlier this week in a Report and Recommendation by Judge Hall—can a prevailing defendant recover attorney's fees under § 285 for work done on a successful IPR petition?

The answer, apparently, is no.

Given the prevalence of IPR petitions, I was somewhat surprised to see that there was no authority on the issue from either the Federal Circuit or Delaware. Judge Hall found the text of § 285 decisive:

The text of 35 U.S.C. § 285 says nothing about giving the district court the ability to award fees incurred by a prevailing party in a separate administrative proceeding. The statute simply states that “[t]he …

In a short ruling issued in Deere & Co. v. AGCO Corp., 18-827-CFC, Judge Connolly rejected the defendants' motion for additional claim construction after IPR. The defendants had asked the Court to conduct further claim construction proceedings on three groups of terms, to account for allegedly inconsistent positions taken by the plaintiff during IPR proceedings on 8 of the 11 asserted patents. Judge Connolly explained that he entertained the motion for more claim construction "based on Defendants' repeated and emphatic representations that Plaintiff Deere & Company maintained . . . positions on claim construction [during IPR] that were 'diametrically opposed' to and 'fundamentally inconsistent' with positions Deere took during claim construction before me."

Judge Connolly, however, did not agree . . .

Although the trend in D. Del. is to grant IPR stays post-institution, the inverse is also true: pre-institution have become much more difficult to obtain.

In an oral order denying a pre-institution stay last Thursday, Judge Burke took the opportunity to reiterate why these motions are generally denied:

[W]ith regard to the simplification factor, the Court (absent some unique circumstance not present here) does not see the wisdom in staying a case that is otherwise proceeding forward (with a schedule already in place), in favor of the occurrence of an event (grant of an IPR petition and subsequent institution of an IPR) that has not happened yet. The Court also notes that although, as a statistical …

Yesterday, Chief Judge Stark addressed whether "judicial estoppel" prevents a defendant from taking one position in an uninstituted IPR petition and asserting a contradictory position during claim construction in the district court:

[Plaintiff] Sequoia contends that [defendant] Red Hat is judicially estopped from arguing for a narrower construction than it proposed during the IPR . . . . Judicial estoppel is only appropriate when: (1) the party to be estopped is asserting a position that is irreconcilably inconsistent with one she previously asserted; (2) the party changed her position in bad faith, i.e., with an intent to play fast and loose with the court, and (3) the use of judicial estoppel is tailored to address the affront to the …

In another ruling from the In Re ChanBond litigation as it approaches trial, Judge Andrews today issued an in-depth opinion granting a motion in limine to exclude reference to prior expert testimony from a related IPR proceeding, on the grounds that the testimony is hearsay.

Plaintiff sought to admit the material as former testimony under FRE 804(b)(1), because it is helpful to its infringement case. The rule requires, however, that the former testimony was offered against the parties' predecessor who had "an opportunity and similar motive to develop it."

Here, Judge Andrews found that an IPR petitioner's motive in developing expert testimony to show invalidity is different from a defendant's motive developing its non-infringement position:

We discussed last month how it has, in Judge Andrews' words, become fairly routine for the Court to grant stays following IPR institution. With the recent increase in granted stays, one can see how a litigant might be tempted to fly even closer to the sun, and extend a stay through an appeal to the Federal Circuit.

Judge Connolly gave those gallant dreamers a bit of hope on Tuesday when he granted just such a motion in DDR Holdings, LLC v. Priceline.com LLC, et al., C.A. No. 17-498-CFC, D.I. 101 (D. Del. Jan 19, 2021). In that case, the parties had stipulated to a stay pending resolution of an IPR. When the IPR concluded, some of the asserted claims had been upheld and others had been invalidated, and the plaintiff was appealing the invalidated claims to the Federal Circuit. Plaintiff wanted to move forward with the remaining claims against some of the defendants, while the defendants argued that the stay should continue.

The defendant in M2M Solutions LLC v. Sierra Wireless America, Inc., C.A. No. 14-1102-RGA (D. Del.), argued that the PTAB's previous invalidation of several claims of the plaintiff's patents in an IPR meant that the plaintiffs were collaterally estopped from asserting the validity of the remaining claims—the claims that were not invalidated—at the district court.

Defendant argued that:

  • The Federal Circuit has held that collateral estoppel applies to IPR proceedings generally;
  • The Supreme Court has held that agency decisions may have preclusive effects during later court proceedings; and
  • The Federal Circuit has extended collateral estoppel effects to unajudicated claims when there were no material differences between those and …

Motions to stay pending IPR's have gone through several trends as the IPR landscape has shifted in the years since the AIA created the procedure. In the halcyon days of 2013-2014 when the PTAB was instituting 80+% of all IPR petitions, it was fairly common in Delaware to see stays granted pre-institution. See, e.g., Peschke Map Techs. v. JJ Gumberg Co., C.A. No. 12-1525-SLR (D. Del. Apr. 24, 2014); Princeton Digital Image Corp. v. Konami Digital Entertainment Inc. et al., C.A. No. 12-1461-LPS-CJB (D. Del. Jan. 15, 2014) (mem. order).
