Entries for tag: Claim Construction

Andrew E. Russell

Just last week, we wrote about Judge Noreika ordering an in-person meet-and-confer to occur between lead trial counsel regarding claim terms, in the courtroom in Delaware, and "continuing until excused by the Court." In ordering the in-person meet-and-confer, Judge Noreika noted that the parties had "spoke[n] for just 20 minutes about 10 disputed terms" during their meet-and-confer.

Yesterday, Chief Judge Connolly issued an order along similar lines—but outright canceling the Markman hearing. Like Judge Noreika did, the Court noted that the parties had failed to adequately meet-and-confer about a disputed term:

Plaintiffs first made their new proposal [to construe "tangent"] during the "meet and confer" discussion required by paragraph 13 of the Revised Scheduling Order. . . …

Judge Noreika is well known at this point for requiring real, substantive meet-and-confers on claim construction. In multiple cases, she has directed parties to further meet-and-confer after finding their initial efforts insufficient.

She issued another such order this week, this time directing the parties to have what appears to be a supervised meet-and-confer, in person in the courtroom:

ORDER . . . The parties did not comply with the Court's February 13, 2023 Oral Order requiring a good-faith meet and confer. Instead, the parties spoke for just 20 minutes about 10 disputed terms, as well as "hearing logistics" and a proposal by MarkForged to request deferral of certain claim constructions until dispositive motions. There is no breakdown indicating …

Yesterday, Judge Williams issued a claim construction opinion in Persawvere, Inc. v. Milwaukee Electric Tool Corporation, C.A. No. 21-400-GBW (D. Del. Feb. 21, 2023).

In the joint claim construction brief, plaintiff asserted that defendant had waived its indefiniteness arguments because it did not include them in its invalidity contentions:

Given that Defendant failed to raise an indefiniteness argument in its Invalidity Contentions concerning terms 3 and 4, see Ex. 8, Defendant has waived this defense.

D.I. 47 at 30. In the case, the scheduling order required both initial and final invalidity contentions; defendant did not mention indefiniteness in its initial contentions, and the deadline for final contentions had not yet passed.

The defendant …

No Construction

In Charles Smith Enterprises, LLC v. Catapult Sports, Inc., C.A. No. 21-1278-CFC (D. Del.), the parties filed a 60-page joint claim construction brief that included disputes on a number of terms where one party or the other proposed "plain and ordinary meaning" or "no construction necessary" while the other side proposed a specific definition for the terms.

By my count, for every single one of the parties' 15 disputed terms, one side or the other proposed "plain and ordinary meaning" or "no construction necessary" with no alternative construction—before Chief Judge Connolly, no less. These counsel clearly don't read this blog.

In some instances, the parties just briefed the terms in an odd way. …

We've talked before about a common question in patent cases: whether parties can (or have to) address indefiniteness during the Markman claim construction process. The answer varies greatly by judge.

The Markman process sometimes occurs early in the case, and parties have to make a call fairly early-on about whether they want to address indefiniteness early in the case, or wait until later.

Plaintiffs usually want to defer indefiniteness for later to keep the case going as long as possible. Defendants, on the other hand, can go either way: Often they want to address indefiniteness early to resolve the action, but sometimes they aren't quite ready and prefer to wait as …

This is an interesting order from earlier this month that we never had a chance to post about.

In Ecobee, Inc. v. EcoFactor, Inc., C.A. No. 21-323-MN (D. Del.), the parties had a Markman hearing scheduled for December 8. As she often does, in the leadup to the hearing, Judge Noreika issued an order directing lead counsel for the parties to meet-and-confer to reduce the number of disputes:

ORAL ORDER . . . IT IS HEREBY ORDERED that, on or before 12/1/2022, local and lead counsel (i.e., those attorneys that will be leading trial) for the parties shall meet and confer and file an amended joint claim construction chart that sets forth the …

The Court has said in the past that "winning summary judgment in a patent case is like hitting a hole in one." Well, yesterday DePuy Synthes scored a hole in one, invalidating all asserted claims of one patent on SJ in RSB Spine, LLC v. DePuy Synthes Sales, Inc., C.A. No. 19-1515-RGA (D. Del. Nov. 22, 2022).

How Did They Do It?

Basically, they won it at claim construction, but couldn't end the case until summary judgment.

The patent at issue, U.S. Patent No. 6,984,234, covers a "base plate" that a surgeon can screw into two bones in a person's spinal cord to stabilize them.

The base plate screws into the bones (blue, below), and a …

We got another good data point on Judge William's practices this wekk. In Board of Regents, The University of Texas System v. Boston Scientific Co., C.A. No. 18-392-GBW (D. Del.), Judge Williams denied a non-infringement summary judgment motion—but also scheduled a "mini-Markman" to resolve the underlying claim construction issue.

The defendant moved for summary judgment of non-infringment, arguing that the Court's prior construction of a particular term was incorrect, but that regardless, it would not infringe under either the purportedly incorrect construction or what it alleges is the correct construction.

The Court found factual disputes as to both, and easily disposed of the non-infringement motion.

The …

Defendants often want to import limitations from the specification to the claims. It only takes one missing claim element per claim to defeat an allegation of patent infringement (setting aside DOE). And the language of patent specifications is often narrower than the claims themselves, providing ample opportunities to find limitations.

Federal Circuit precedent, of course, says that the Court should avoid importing limitations from the specification into the claims—but using the specification to interpret the meaning of a claim is OK. Phillips v. AWH Corp., 415 F.3d 1303, 1323 (Fed. Cir. 2005). As countless courts have recognized, that is a fine line.

As a result, defendants' early-case strategy often …

In an opinion today, visiting Judge Kennelly (N.D. Ill.) rejected the idea that an accused infringer could bring an IPR, receive a claim construction in that IPR, and then argue that that construction is "intrinsic evidence" that, by itself, merits adopting the construction in the district court case.

In XMTT, Inc. v. Intel Corp., C.A. No. 18-1810-MFK, D.I. 293 (D. Del. July 22, 2022), the PTAB had proposed and applied its own constructions for the claims, and accused infringer Intel ultimately lost the IPR. Intel then appealed, and the Federal Circuit affirmed without reaching the merits of the claim constructions.

While the IPR was pending, Intel argued that the …
